??Discount car electronics resolve how the sound is generated in the car audio system?
??While many owners like friends immersed in the world of music, but for the sound and how generated presumably few people will know. Like the variety of voices in the air, no matter what form they have, are caused due to the vibration of the object. Next, take a look at the car audio system sound generation. automotive electronics suppliers.
??The sound of car audio sound source must be spread out through the middle of the medium to the people most familiar with the sound transmission medium is air, in addition to the gas, liquid and solid can also carry sound. Barking of the speed of propagation of the vibration in the medium-speed, the speed of sound in the medium of any one, depending on the elasticity and density of the medium, therefore, the velocity of propagation of sound in different media is different: in the propagation velocity of the liquids and solids in general than much faster in air, for example, the sound speed in water as 1450m / s, compared to 5000 m / s in the copper.
??The car stereo, the propagation speed of sound in air is also increased with increasing temperature of the air. The forward air vibrations known as sonic, acoustic wave propagation space grunting field. Acoustic vibrations in the air in the dissemination of space-time the temperament point is not being taken away, it's just back and forth vibration near the original position, so the sound propagation is the transmission of vibration.
??Object leaves the distance of the rest position of said displacement ?, the maximum displacement is called amplitude ?, the the harmonic vibration displacement in relation to time is expressed as the ? = ?Sin (2?ft + ?), where f is the frequency, (2?ft + ?) is called harmonic vibration the phase angle, it is decided the important quantities of the state of motion of the object, determines the size of the intensity of the sound amplitude ?.
??Always, each object in the world when the vibration occurs at the time will produce the sound, the sound emitted object known as the sound source. If the vibration amplitude of the object such as a sine curve, as the change over time then this vibration is called harmonic vibration, an object with a simple harmonic motion when the air around the dot for simple arrangements vibration.

Ibuonline platform Custom printed circuit board manufacturing pointed out three common errors in the PCB

By tingyuya

??Ibuonline platform Custom printed circuit board manufacturing pointed out three common errors in the PCB
??(1) network load report NODE did not find: a schematic diagram of the components used pcb library package; b schematic elements using the the pcb library name inconsistent package;
??The schematic components used pcb library pin number inconsistent package. Such as transistors: SCH in pinnumber e, b, c, the pcb 1,2,3. circuit board manufacturing companies.
??(2) can not print to a piece of paper when printing always:
??Create pcb library is not at the origin;
??b. multiple moving and rotating components hidden characters pcb board sector. Choose to display all hidden characters and narrow pcb, then move the character to the border.
??(3) DRC reporting network is divided into several parts: indicates that the network is not connected to see the report file, use CONNECTEDCOPPER Find. Another reminder friends use WIN2000, as far as possible to reduce the opportunity of a blue screen; export file more than a few times, made new DDB file to reduce the file size and PROTEL dead opportunity. If we make a more complex design, try not to use the automatic routing. PCB design, wiring is an important step in the completion of product design, it can be said that previous preparations are done for it, the entire PCB design process of wiring limited to the highest, finest skills workload. PCB layout sided wiring, double-sided the wiring and multilayer wiring.
??There are also two ways: automatic wiring and interactive routing wiring before the automatic wiring, can be used interactively in advance and more stringent requirements of the line wiring, the input terminal and the output side of the edges should be avoided for the adjacent parallel, so as not to generate the reflection interference. If necessary, add ground isolation, the two adjacent layers of wiring to be perpendicular to each other, parallel prone to parasitic coupling.

??For constant concern Automotive News readers should know that some time ago, Hangzhou-Pudong Expressway on a coupe turned on the cruise control function can not be turned off, eventually unwinding ordered cruise control of the thing can not be lifted. After this incident, the users in the country led collective onlookers. Heard of the event, many car owners will never have dared to use the cruise control?automotive electronics suppliers.
??In response to this event, the next we talk about car electronic equipment should be the selection and maintenance of:
??1, the electronic equipment is more maintenance more important
??Ibuonline many maintenance experts pointed contrast, more models of electronic aids, the more we need to pay attention to maintenance. Ibuonline discount car electronics center pointed out that numerous safety auxiliary system R & D is relatively mature, under the premise of failure, the reliability is high, but has a higher demand on maintenance. Such models need to rely on a large number of sensors or cameras, radar equipment and other work also greatly increased the risk of damage. In the same time, these models put forward higher requirements for maintenance level, it is recommended that these vehicles to select professional maintenance plant maintenance. Need to be reminded that when these sensor or camera failure, these auxiliary equipment will be useless, and may even be misleading motorists.
??2 more electronic equipment failure rate the higher the
??From the point of view of traffic safety, to ensure that electronic aids normal use, its contribution to the security role, such as extensive use of ABS, EBD. Its positive energy, when a fault occurs, the application of electronic equipment, may affect self-help.
??The maintenance staff pointed out that less electronic aids because of the low distribution models, body sensors is also less chance of failure is relatively low. If the owner is not willing to bring for these must facilitate electronic aids to pay additional maintenance costs, the owner is the best choice for a relatively small number of electronic aids low-equipped models. In general, equipped with ABS, EBD models to meet the normal requirements.
??Environment is poor need to shorten the maintenance cycle.
??Extensive use of electronic equipment, will also put forward higher requirements. Waterproof, dustproof Ibuonline platform car electronic maintenance engineer pointed out that the electronic auxiliary equipment most need the the default through sensors, cameras, remote control devices, or trip computer program work may lead to the sensitivity of the device when a vehicle collision or sensor encounter muddy occlusion, or accurate sexual deviation, while the owners to place undue reliance on these auxiliary equipment, may depend. Smart cruise, for example, to maintain a safe distance from the sensing system at the front, such as the front collision or long-term driving on bumpy roads and the vehicle in front, it will be more chance of sensor damage. Therefore, to use these models of electronic equipment in harsh environments, should be appropriate to shorten the maintenance cycle, and frequent trips to the 4S shop maintenance.
??The high-tech smart car electronic equipment for the owners of their day-to-day driving life played a tremendous help to remind the majority of owners friends here, owners should carry out maintenance of vehicles in a timely manner, to ensure the normal use of the electronic devices. In addition, the owner should sober understanding of the electronic device can only play a supporting role, can not be over-reliance on them.

Ibuonline Discount car electronics share nine characteristics of the running-in period of new car

By tingyuya

??Ibuonline Discount car electronics share nine characteristics of the running-in period of new car
??1, running failure: due to improper assembly of parts, car driving more faults in the running-in period;
??2, high oil consumption: to ensure that the new running-in stage operation in low load condition, the carburetor car installed limit, therefore, extremely easy to cause the mixture too thick, so that the fuel consumption increases; automotive electronics suppliers
??3, oil deterioration: the new car in the running-in period, because part of the rough surface and between the two parts of small gap, will make the oil temperature, at the same time, a lot of scrap metal is worn fall into the lubricating oil, easy to make the lubricating oil oxidation and metamorphism.
??Said the following matters needing attention in the running-in period when using the new car:
??1, the initial preheating first: This is for EFI cars, starting before, should first turn the key to the second stop after 5-10 seconds, restart, this is because the key after the door is opened, the gasoline pump starts to work, the oil pressure and injection quantity adjustment, therefore, a few seconds after the start to protect the car engine;
??2, avoid the emergency brake: emergency brake not only make the running in the brake system will increase the impact load impact, the chassis and engine, the first driving 300 kilometers, it is best not to emergency braking;
??3, avoid overload: the new car in the running-in period such as the full-load operation, will cause damage to parts, therefore, in the initial driving 1000 kilometers, homebred car can not exceed the rated load 75%-80%, imported cars can not exceed the rated load of 90%, in addition, in order to reduce body and power system load, road surface should be flat, avoid vibration, crash or emergency braking;
??4, avoid to run long-distance: new car in the running-in period to run long-distance, engine continuous working time will increase, easy to cause the wear of machine parts;
??At 5, not high speed: the new running-in stage within the speed limit, domestic car in general 40-70 km / h, imported cars generally at 100 km / h, when the throttle opening, vehicle speed can not exceed the maximum speed of 80%, and in the running to observe the engine tachometer and speedometer, ensure that the engine speed and the vehicle speed speed in the work, under normal circumstances, the running-in period of engine speed should be in 2000-4000 rpm;
??6, the use of high-quality gasoline: car used in the running-in period of not less than the manufacturer of the gasoline label, should try to add high-quality gasoline, do not add wear resistant oil, so as to avoid the mileage is enough and running-in problems;
??7, avoid early dismantling limit: limit is a throttling device installed on a carburetor and air inlet pipe between the owner cannot advance, it should be removed, such as car 1000 kilometers, in the maintenance of good circumstances and will be removed;
??8, timely shift: shift in time to avoid the high gear and low speed and low gear of high speed driving, not by a long way, but also not in each gear so the speed limit is reached, in general, the gear speed control at top speed in the range of 3/4, specific for: 1 block 25. In 2, retaining 40 km, 60 km, 3 Block 4 block 5 block 90 kilometers, 100 kilometers;
??9, the correct adjustment of ignition and fuel system: this can solve the changes caused by vacuum economizer installed limit occurs, raise economy to adjust period.

Custom printed circuit board manufacturing wastewater treatment methods and process

By tingyuya

??Custom printed circuit board manufacturing wastewater treatment methods and process
??The printed circuit board wastewater commonly used method of sub-quality processing.The complex copper wastewater treatment: because of the complex copper (EDTA copper complex ions or copper ammonia complex ion, its structure is quite stable, dissolved in water, does not precipitate), generally only 1% of the total amount of water to 3%, but because of its The complex is extremely stable, if not get rid of the complex, and the effluent copper ions certainly not standard (0.5 mg / L or less). Complexing copper wastewater are mixed together with other sewage treatment, the dosage to break the complex is very large, the running cost increases. Complex copper wastewater must be pretreated?circuit board manufacturing companies
.
??Ink wastewater treatment: developing, stripping wastewater, its main feature is CODc high concentrations. Up to 15 L, Cu2 approximately 10 mg / L, developing, stripping wastewater organics precipitation have a large impact on the back of coagulation. Its characteristics are easy to precipitate under acidic conditions. Therefore should not be mixed with other wastewater treatment. When larger amount of water under acidic conditions (pH 2-3), all wastewater pumped to the a specialized filter press filter press, filtered water to drain to the total adjustment pool.
??Electroplating wastewater treatment: wastewater containing cyanide and chromium ions in electroplating wastewater can be incorporated into the ordinary copper-containing wastewater. Containing cyanide or chromium at the break cyanide or remove chromium electroplating wastewater treatment process pretreatment, and then processed together with the ordinary copper-containing wastewater.
??Below is a wastewater treatment process
??The figure shows that the circuit board production workshop by water quality, 7 classes wastewater, in addition to the ordinary copper-containing wastewater directly discharged always adjust sump, and the other six kinds of wastewater sump row of six small, during pretreatment row always adjust the sump. Pretreatment:
??Oxidation reaction (1) complex copper containing effluent copper replacement reaction pool a total adjustment sump. The copper replacement reaction is generally conducted with a ferrous salt, and the reaction usually in the pH = 7. Configure the pH value, ORP controller and automatic dosing equipment.
??(2) developing waste water acidification a pH adjusting a total sump. Developing Tuomo (ink) wastewater organics concentration is very high, up to 1.5 L, the wastewater in the pH = 2-3 when chemical reaction occurs, a large number of ink slag floating. The subsequent processing wastewater CODc approximately around 2000. And ink wastewater water is large, to reduce the influence of the subsequent processing step, the ink wastewater acidified deslagging, the need for a biochemical treatment, into the total adjustment sump, but this method involves too many factors, in particular the copper ions the microbial toxic effects should note. The elegant new operation showed that the treatment was not successful. The acidic wastewater dosage savings, reduce operating costs, adjusting the pH value of the ink wastewater For biochemical treatment, whether the other ingredients should be considered acidic wastewater microbial influential.

Automotive electronics suppliers storage of common sense: the Spring Festival holiday auto store need to pay attention to 4 key points

By tingyuya

??Automotive electronics suppliers storage of common sense: the Spring Festival holiday auto store need to pay attention to 4 key points
??The lunar new year will soon be over, we ibuonline to summarize during the Spring Festival car storage knowledge, saying " it, too late ".
??Both the choice of car travel during the long holiday or rest in the home, many netizens or will the private car is stored for a period of time. The car park is not a long time maintenance of the road, in order to ensure the smooth work after ibuonline, discount car electronics wholesalers suggest broad netizen attention to 4 key points of maintenance during storage. automotive electronics suppliers
??The place for a long time, don't forget the tank
??The store a few months gasoline may deteriorate, on the other hand, oxidation and precipitation of gasoline, fuel system and may even block car. Of course you can be discharged from the fuel tank of gasoline, but to do so but may cause fuel tank and fuel lines and rust due to moisture. In order to avoid this situation, in gasoline by adding a stabilizing agent is a good way to.
??Remember to every two to three weeks to start a your car, although cars have been stored up, but still want to keep the cylinder lubrication: the car to run for 20 minutes, or until it reaches the desired operating temperature.
??Check "two solution ", in your heart
??Automobile engine is the heart of winter, long-term placement of automobile, there will be damage to it, the importance of self-evident. "Two solution " ( antifreeze and oil ) on vital engine maintenance.
??Generally speaking, the antifreeze every two years a change, if the repair process or emergency once in the antifreeze added in ordinary water, then the antifreeze even less than two years, or must be replaced. The most important use of antifreeze is according to different regions and different models to determine the freezing point and the amount of antifreeze. Freezing point can check antifreeze antifreeze brand understanding, the freezing point is about 30 degrees below zero, but in general, freezing point of liquid coolant than vehicle minimum temperature region of low 5 to 10 degrees celsius.
??If not promptly replace the oil used in the winter, will cause the car to start when the cold start difficulties, or even tile kilning accident. Therefore, in the winter comes, should be promptly oil pan, air compressor oil into the oil used in the winter; the transmission, sub-actuators, differential, steering gear oil is in gear oil for winter; the hub bearing cleaning, add bearing lubricating oil with low viscosity.
??" Hibernation " to full power
??If the engine at startup or laborious is barely started after the speed gradually decreased the battery voltage is less than, need to recharge. Secondly, attention should be paid to the height of liquid level inspection of electrolyte battery, open the battery cover with water after they saw, in the battery side will be marking, lower level in general, the electrolyte level should be higher than the plate on the margin of 10 to 15 cm. Once the water level is lower than the line, to add distilled water or liquid battery, do not add water, this will result in battery damage.
??The vehicle even if the long-term placement not, remember that often " start ", there is always moving your car, don't let the car tires are always in a position, then is to remove the battery connection, this can prevent the battery discharge, battery power loss prevention, when used with.
??Inside and out, keep clean
??Cleaning and the waxing, ensure the vehicle is dry and keep dry, because the wet auto save the biggest enemy; put a bag of desiccant, in the car such as silica, thereby absorbing excess moisture inside the car, especially in the winter and wet the most serious coast area; at the same time to solve the carpet or bedding material. Stains, lest they never cleaning; also can use silicone spray or glue lubricating all doors, hinges, weather strip.

By tingyuya

??Ibuonline circuit board manufacturing companies examples analysis accurate repair machine three fault solution
??The judgment is accurate, concise and repair method of work time is short, so we must accurately judging the fault position, take the simple repair method for repair, in the shortest possible time to solve the problem. In the replacement of parts, should choose good quality accessories, installation work accurately, avoid to leave behind the future trouble. Here are a few examples of daily repaircircuit board manufacturing companies..
??Fault 1: Feida paper always drive the noodle
??Manufacturers approach: repair Feida valve -- scraping valve shell hole, electroplating valve spool, replacing the paper round.
??Error: after repair of valve leakage is more serious, the replacement of the quality of the paper round as before.
??Right way: the paper skew is the main cause of machine installed at the feeder and host does not parallel, correction feidahong relative to the host parallel degree.
??Fault 2 : printing, appeared " peeling" fault
??The operator approach: regulation of nano-imprint lithography drum teeth on the adjusting screw, attempts to increase the teeth in its paper force.
??Error: Heidelberg printing machine teeth in its paper force by the spring force and the tooth machining precision, the above methods can not adjust the teeth in its paper, and can only change drum tooth row over time, causing the overprint fault.
??The correct method: check radiograph and dental pad wear, replace if necessary; check the teeth on the presence of " dead teeth " and " dead teeth " problem; check the tooth row between the connection, make adjustments if necessary.
??Fault 3: "" and swing angle fault
??The operator approach: regulating the collection of paper drum teeth pedestal beneath the screw, adjust the ink viscosity, regulating the printing pressure.
??Error: regulating the collection of paper drum teeth pedestal beneath the screw, changed the collection of paper drum tooth pad height adjustment datum, so that future correction more cumbersome; the ink viscosity and printing pressure to be printed in accordance with the needs are identified, not because the overprinter problem and change. These methods can not solve the problem of printing "" and swing angle.
Note: the use of necessary for many years and have not been system repair equipment, widespread presence " and swing angle " fault. Cause this kind of fault factors, only in the equipment maintenance, can be thoroughly solved.

By tingyuya

??Ibuonline circuit board manufacturing companies decryption seven measures to solve the mechanical stick dirty
??Is up and down two sheets from sticking together, the sticky dirty essential reason is that the ink is not completely dry, and thus how to make sheets dried quickly solve sticky dirty.
??1 using quick-drying ink. Especially multi-color printing, the ink dried quickly extraordinarily important. Found that the ink drying too slow, you can add a small amount of desiccantcircuit board manufacturing companies.
??2 Use the pH value of close to dampening governance. The pH value is smaller, the longer the drying time of the ink, should reduce the concentration of the fountain solution.
??Increase the the duster amount. Dusting larger the amount of sheets spaced between the greater area, thereby allowing the ink drying time long enough.
??Ensure the right temperature. High temperature, the faster the speed of the ink oxidation conjunctiva.
??5. Improve ventilation performance. Ventilated better, faster ink drying speed. It should be noted that the semi-finished products can not do so. In addition, as when the ink oxidation conjunctiva produce heat and thus ventilation allows for heat dissipation.
??6. The brake roller inspiratory capacity should not be too large. Should enable the sheet between the presence of a certain amount of air, to prevent the sheets of the partial vacuum state.
7 sheets should not be piled too high. Too high due to the weight of the paper is too large, may result in lower paper glued together.

??Ibuonline automotive electronics suppliers to talk about three kinds of alternative fuel economy Raiders
??Recently, a further rise in oil prices. The reporters found that the advertising of all kinds of fuel-efficient products, began to occupy a prominent position in the automotive supplies market. With rising oil prices, a lot of people heard the "fuel-efficient" to immediately shines. Older products in addition to what the fuel economy stickers, fuel economy, additives, some the sound Xuanhu "fuel-efficient Product" and in recent years also constantly broke into the horizon, such as fuel-efficient tire, fuel-efficient explosion-proof film, even navigation Miriam also something to do with fuel-efficient.
??Whether these alternative fuel-efficient products, businesses are grandstanding hype gimmick or practical new concept product, the reporter with industry experts from their fuel-efficient principle analysis, as well as how to objectively look at its "fuel-efficient" function.
??Fuel-efficient tirecar electronic parts
??Fuel-efficient Keywords: reduce rolling resistance
??With the listing of the new generation of fuel-efficient tire, tire manufacturers have once again played the "fuel-efficient" brand.
??Fuel-efficient principle: usually high silicon content of the tires have a relatively excellent grip, less energy loss, can effectively reduce the rolling resistance, more fuel-efficient than ordinary tires.
??Expert analysis: In fact, the tire has been able to fuel economy, relies mainly on reducing tire rolling friction to achieve their goals, in addition to the tire pressure, tread, flat rate are also factors affect whether it is fuel-efficient. Four fuel-efficient car tires, in theory, may drop about 5% of the fuel consumption.
??Blast-proof film
??Fuel-efficient Keywords: reduce consumption of air conditioning and refrigeration
??Some car film brand to attract the consumers of thirst for fuel-efficient, more specialized in the product launch of the "energy-saving series.
??Fuel-efficient principle: hot summer, the exposure sometimes under the temperature inside the vehicle or even up to 60 ° C, turn on the air conditioning can cool, but the use of air conditioning in the summer heat for a long time, the fuel consumption will inevitably increase. Car film has excellent spectral selection effect, can effectively reduce the visible and near-infrared energy into a corresponding reduction in the consumption of air conditioning and refrigeration, as the temperature drops, so as to achieve the energy saving effect.
??Expert analysis: by effectively reducing the visible and near-infrared energy into, and effectively improve the Solar Energy Rejection, from this angle, and allows the air conditioning to maximize the effect, to reduce energy consumption. In general, however, even if it is a very good car film insulation effect, and its energy-saving effect only in 2% to 8%.
??Navigator
??Fuel-efficient Keywords: reduce mileage
??Navigator fuel-efficient, it sounds a little joke taste. Think navigator in an unfamiliar place detours, it seems that we can play the effect of fuel savings.
??Fuel-efficient principle: in fact, this navigator can also fuel-efficient concept is fairly simple. It lies in reducing the mileage, the case does not get lost each trip can rapidly reach their destinations, so in terms of its reduced fuel consumption, principle is simple.
Expert analysis: from theory to reduce the mileage to be more direct and effective than what other lower rolling resistance to reduce the fuel consumption of air conditioning and refrigeration. However, in practical applications, many vehicle owners will have a different experience. First of all, we are more familiar with the place, the navigator will basically be ignored, and in the rush hour, frequent traffic jams is also difficult for static navigator their talents. But in a strange place, it will play, compared to the unnecessary distance to go in the state lost more than it naturally helps to reduce fuel consumption.

??Emergency repair of chassis
??In the far away from the garage, car has broken down, it really is a headache for the people. There is no patient preparation, a car in normal should pay attention to the vehicle maintenance.
??When it comes to automobile maintenance, chassis care most easily driver friend ignored, but in the winter or wet weather chassis maintenance quality importance is obvious. In the winter the chassis maintenance will be done chassis cleaning and rust prevention treatment. First of all to the chassis to thoroughly clean the dirt, if the chassis is excessive, but also with greasy dirt detergent wash again, make the chassis with the original " color ", so rust preventive care before they can begin to. In the professional beauty shop, the car rises to the lifting frame on the chassis cleaning, wipe, and then rust preventive nursing. In the middle of this note, cleaning must wait for the chassis of the water after the dry, can undertake antirust nursing. In nursing, be sure to keep uniform spray coating, to form a layer of retaining enduring uniform antirust coating. Completed after 5-10 minutes to dry naturally, anti-rust chassis processing is not complete.
??Finished professional chassis after care, does not mean that no danger of anything going wrong, in which there is an error, it is often the people to car to car to wash, which often add some cleaning agent, then please do not use alkaline cleaning agent, washing powder, washing the body and chassis, otherwise it will affect the antirust effect shortening and antirust time.
??Suggest you go to a professional beauty shop to do hand care, its quality has a simple method can test out : finish rust preventive nursing in high pressure water jet washing chassis after almost not hanging drops, this effect only represent genuine goods at a fair price nursing, can play a very good antirust protective effect.
??Automobile chassis parts are damaged emergency well
??When the vehicle is in a field or away from the vehicle and chassis parts are damaged when meeting place, according to the different fault conditions, can use the following method of first aid drove up in places where conditions.
??Brake branch pump leakage of brake fluid or branch pump pipeline break, the branch pump pipeline joints with tin, copper skin to make a small cushion, the line closed, screwing the screw, or fracture clamping, crimp plugging, the wheel brake used as. But doing so may cause unilateral brake, driving to safety first.
??Braking general pump for lack of brake fluid, can be used in lieu of alcohol or spirits, special circumstances can be used instead of water. Brake cup made up, will be made up the bowl on the hot water soak 10 minutes -20 minutes, the bowl on the oil removed, so that the leather bowl to restore the original size.
??Clutch friction plate skid ablation, ablation is not very serious on the friction plate, can be used over noodles. Such as ablation of serious, available cotton or canvas layer (the thickness with the original agreement, friction plate ) with wire or wire through the hole on the steel plate, which are fixed. When driving a vehicle should be a smooth start, quickly shifting action.
Tie rod joint is broken, the bumper or other does not influence the driving place, unloaded with a ball joint total length similar screw breakage, replace the fetlock, mounted on the steering knuckle arm and a nut, screw part with a hammer riveting. Three axle vehicle differential gear damage, such as, the rear axle differential damage to any one, can be the bridge and axle shaft removed, continue to run. If the front differential damage, the hub of bond remove rear drive.

??Ibuonline custom printed circuit board manufacturers skillfully avoid rubbing dirty strategy
??Rub dirty sheet surface in the course of the campaign, with some parts of the machine occurred to interfere with each other.
??1 pick roller and the pressure roller pressure is too great. Too much pressure between them, the result is the shape contour of the pressure roller pressure to the front of the sheets, textured lines on the pick roller or cross fold pressure to the back of the sheet. Because they rely on friction drive between them and the sheets there is relative sliding, so that the front or back of the sheets, soiled. Reducing the pressure of the platen roller.
??Too much pressure the the feeding panel grid paper cloth belt and the pressure between the roller. Thus cardboard between the pressure roller, paper, the feeding cloth belt and lose are likely to produce tiny relative slip, so that the printed product front or back rub wins. Tensioning the sheet feeding cloth belt, reducing the pressure of the platen roller. Another feeding brush on the other parts have to adjust the appropriate sheets front so as not to rub dirty.
??3. Ordinance the platen lift is too late. Clapped too late, when the sheets forward movement of prints of the surface and the rules of the board and measured Damper there is friction, so that the surface of India rub wins. Pull the paper time to adjust the side lay it lifted earlier.
??Before want to return a gift with the paper surface. The former regulations timing is incorrect, re-adjust. The former the regulation cap is too high, lower the height of the former regulatory cap.
??The 5. The gripper teeth backhaul and paper surface relative rub. Pressure roller is not installed, the paper upturned too big; the gripper teeth above Tropsch paper feed mechanism running inflexible; paper is too thick not bend easily, replace the paper. PCB manufacture and assembly
??Prequel roller and transfer the supplier surface back dirty.
??(1) anti-rub dirty cloth has not achieve anti rub the role of anti-surface elastic anti-rub win, lose their elasticity would not achieve anti-rub dirty, soiled cloth, then should replace the anti- , soiled cloth.
??(2) anti-rub dirty cloth installed too tight or too loose but there is no anti-rub dirty reinstall.
??(3) anti-rub dirty cloth its the ink surface swim plot and too many impurities and printed materials formed on the surface of tiny relative slip, causing the surface of the printed product, soiled.
??Sheets along the shift drum tooth row. 7 will chase into pro surface road wins. Check tooth row bite force, reducing the viscosity of the ink and to reduce the printing pressure.
??8 sheets in the closing roller surface rub handling stolen goods. Sheet to the closing roller, the thickness of the ink is the largest, and therefore most likely to rub dirty. And should therefore be as far as possible so that the printing pressure of the last group are smaller, thereby reducing the sheet the possibility of relative sliding in the closing Zhang drum.
??9 anti-rub institutions will not achieve anti-gift dirty role. The closing paper part of the anti-rub dirty institutions generally use the anti road wins cloth with wins gas line anti-rub. The anti rub wins cloth with the role of anti-rub dirty cloth similar to the causes of its failure and exclusion is also similar. In theory, it is best to make the site of the collection of paper, the paper has been suspended in the air, thus multi-gas path to achieve anti-rub dirty. Blow to the sheet below using pressure to float the paper, if the gas line work is poor, it will cause back rub dirty.
??10. Plain paper, soiled. Flat paper itself is almost the entire paper tail, but when the flat paper inhale too, so the the sheets back of flat paper close contact, causing the back, soiled, so generally upside down printing plain paper without devices.
??11. The brake rollers induced surface rub to handling stolen goods. Similar to the principles of peace, soiled paper, troubleshooting methods are also similar.
??12 jogger institutions caused the sheet surface, soiled. Jogger institutions neat sheets, the sheets in the collection of paper heap there is a certain amount of sliding, so that the back of the printed product, soiled. Properly adjust the location of the jogger institutions, its impact on the press sheet minimum.
??13. Sheets also cause heap sliding in the collection of paper, soiled surface. So just printed the finished printed product should it remain stationary in the delivery pile, do not hand look through.
14. Other band member causing the possibility of rubbing dirty. Sheets in the printing process through which the various parts of the route should be in normal working condition, but some loose parts or improper installation, deviated from the normal position, then it is possible to cause surface, soiled. Therefore encountered failure, soiled, should take a close look.

??Ibuonline discount car electronics teach you car tire maintenance 7 Great Tips
??The continuous improvement of the car costs, forcing people did not miss any details of the expenditure savings. In fact, quite a percentage of the cost of the car process supplies tire, 4 tires worth thousands of dollars, if used improperly can result in abnormal loss of the owners of the purse, but a huge blow! Coupled with the recent volatility of the international tire market The tire price trend anxiety. We can not control the price of the tires, how to reduce tire wear and maximize the life of the tire is the owners who must master knowledge. Car driving with tire wear have a great relationship. Good, skilled driving techniques can effectively reduce tire wear and extend tire life, while improving driving safety. The following summarizes several tips to reduce tire wear.
??Pressure to compliancediscount car electronics
??Driver in accordance with the provisions of the depot to the tire inflation. When the tire pressure is lower than the standard value, the wear of the tire shoulder increases sharply;, due to the decrease in the ground contact area of the tire when the tire pressure is higher than the standard value, the unit pressure increased, so that the tire tread central increased wear, while increasing the tire rigidity. dynamic load load increases, the wheels are prone carcass burst.
??Tread no cracks
??Regularly check the tire surface cracks, deformation and other defects. Tire groove travel wear faded, the polished will lose drainage non-slip, the car of the performance will be greatly reduced, while seemingly small crack high speed flat tire hazard. Moreover, you should pay attention to the timely removal of the groove in the gravel.
??Parking election plains
??To avoid the vehicle parked in the coarse, sharp or sharp stones on the road. Vehicles do not park close to or in contact with petroleum products, acids, and other places affect the the rubber deterioration of materials. Driver do not turn the steering wheel after parking, this operation will accelerate tire wear.
??Heat do not splashing
??Easily overheated when the tire driving or high speed a long time in summer, while increased pressure. You should stop cooling, the non bleed buck or splashing water cooling, in case of non-normal aging of the tread rubber.
??Avoid braking
??Started can not be too much force to avoid frequent use of the brakes and the emergency brake to avoid accelerated tread wear due to the drag of the tire and the ground; turning the car will overtake when a lot through the intersection, narrow road, railway crossing, should have the appropriate speed and to pay attention to the road, pedestrians, vehicle dynamics, to do brake ready to reduce frequent braking to avoid the emergency brake, thereby reducing tire wear; faced with broken glass or other foreign matter that can not be avoided, to reduce speed by, do Do not slam the brakes because the brakes causing the pressure increases, the glass debris and foreign objects easier to tie into the tire.
??Selecting pavement
??Highway repair and construction sites and driving the application of low-speed amble choose the road of the way through, to avoid tire subjected to excessive crashing even stabbed or scratched; driving on uneven roads, one should choose the road to reduce tire and road crashing, avoid parts and tire damage; Second, to reduce speed to be put on hold to avoid the tire bumps and strong vibrations; through muddy lots, should choose a more solid, does not slip through the place, so as not to tire subsidence situ idling, intense heat caused The tire sidewall serious cuts, scratches.
??Control speed
Vehicle turns should bend the road, turning radius, generally appropriate deceleration to avoid tire wear due to the inertia force and the centrifugal force, acceleration unilateral; downhill should be based on the slope of the size, length and road conditions, to control the appropriate speed avoid little use of the emergency brake, reduce tire wear; parking and vehicles driving on the way to the station parking should develop safe taxiing habits.

??Ibuonline custom printed circuit board manufacturers solve the wear plate 13
??The wear of the printing plate in the printing process is inevitable, but if taken normative operation, causes the speed of wear of the printed version of the greatly reduced. Essentially because of the wear plate relative slip friction plate and other parts in contact with each other parts of the relative contact surface. Therefore reduce the wear on the plate is to reduce friction.
??1 the water roller relative slip between the plates.
??(1) The water roller and the plate with pressure between the water roller string water roller ranging re-adjust to make it equal to the pressure.
??(2) water roller circle with caliper detection. Exceed the requirements should be replaced.
??(3) water roller above Molton too loose, the results of the individual parts to a regulatory creases, resulting in wear plates.
??(4) the surface of the water roll hard points such as ink above, such as cleaning the water roll. PCB manufacture and assembly
??(5) water the roller surface water glue velvet has been largely off replacement Molton.
??2 inking roller plates shift relative along. The causes of its failure and exclusion. "1".
??Uneven surface of the plate. Projecting pressure areas most likely to be worn, to replace the plates, to select the better flatness of the plate (surface roughness ? ± 0.02mm).
??4. The plate following liner uneven or there will be nodes will cause the plate above the corresponding position in accelerated wear. Replace the gasket.
??Above the plate cylinder with dirty or beating exceed requirements can also cause wear plates. Keep the plate clean if off should promptly wipe; check the beating of the plate cylinder meets the requirements, such as the excess of the allowed values should find the reasons in a timely manner, and be excluded.
??6 suppliers and ideal printing plate roller mounted on the printing plate after the printing plate cylinder diameter does not match, so that the tangential speed of the contact surface are not equal, resulting in the wear plates. Re-select a bag lining of the drum, so that their surface speed as uniform as possible.
??7. Rubber caused by the beating of the drum itself plate wear. Check the bushings on both sides of its state of wear, such as to exceed the permissible value should be promptly corrected.
??8. Blanket unflatness plate wear faster. Replace the blanket.
??9. Rubber roll supplier Kanemura diameter does not match the ideal diameter, can also cause wear plates. Solution with "5".
??10. The printing pressure greater than the standard pressure plate will wear faster. Reduce the printing pressure.
??11. The viscosity of the ink can also cause wear plates. Reduce the viscosity of the ink.
??12. Viscous blanket can also cause wear plate. Replace the blanket.
13 machine vibration caused by wear plate. Choose the machine speed, the use of a small printing pressure measures to reduce the vibration of the machine.

??Ibuonline discount car electronics on whether oil better on the car better
??Automotive quality better oil or gasoline, the car will be better? To this, Ibuonline discount car electronics repair professional advice, if necessary, may wish to use a little better quality oil and gasoline.
??Gasoline is better quality on the better car?
??The new owners Miss Mok referred to the car, the 4S shop staff told her, new run-in period, preferably with higher quality grade of gasoline to use, so you can make the engine work better. Miss Mok said read instructions, know your car just add 93 gasoline is suitable, why 4S shop but remind yourself to add 97 gasoline?
??For Miss Mok 's questions, auto repair professional master Wei said, will miss Mok models, plus 93 gasoline is not on car has been damaged, and the car descriptions also shows that the model is suitable for the above number 93 gasoline, i.e. if Miss Mok to add 97 gasoline also won't have any problem.
??" 4S store put forward new plus 97 gasoline or just out of a kind, because of the high grade oil or will be better, the new car, the engine or will be better, if the conditions of the vehicle during use, can also use a higher grade of gasoline. " Wei master point.
??For the automotive repair professionals, Molinaro also have their own ideas, she thinks, current gasoline prices so high, but if we start with high grade benzine, after a run-in period with low grade benzine, whether it will damage the engine? For Mo Xiao 's worry, master Wei said do not have worry, Wei said master, now many luxury car occasionally with 93 gasoline, and two gas exchange, is advantageous for engine. But, must be to the regular gas station to refuel.
??Good oil on the engine.
??Compared Yumo Miss new car to add what grade of gasoline and entangled, Jiang Yan, a headache, because the car to do maintenance. The last maintenance, 4S stores to miss Yan car to replace the imported synthetic motor oil, because the staff said that this oil on the engine of the car is very good. However, Miss Yan friends said to her, her car is seventy thousand or eighty thousand yuan, there is no need to add such a good oil, plus the general oil line.
??For automotive oil change for the better quality will be on whether the better car? Wei Master said, this should be wide open to interpretation. He thinks, oil is consumable, everyone is different. But for the seventy thousand or eighty thousand family car, with five hundred or six hundred yuan of imports of fully synthetic oil with a bit of luxury, but this money well spent, not wronged, good engine oil to engine is still good.
The reporter also from 4S shop after sale service to understand, owner to do maintenance, 4S shop is for the owner of the car in exchange for the original oil, because the factory used by the oil models are standard. However, there are automobile professionals said, some 4S shop to earn more profit, also in the owners to do maintenance, to the owners to sell some similar imported synthetic oil. In fact, the owners as long as we persist in replacement of original oil, then the car's engine is no harm.

Ibuonline custom printed circuit board manufacturers share paper tearing problems in mechanical repair application

By tingyuya

??Ibuonline custom printed circuit board manufacturers share paper tearing problems in mechanical repair application
??Paper tearing mouth is a paper surface parts of torn. The paper raise export essential reason is the mutual interference between moving parts appeared.
??1 side up too late. The paper teeth in its paper from transport board, ritual has not raised, causing the ritual at the paper is torn. Adjustment rules below the cam, so that the rules in advance of lift.
??2 the former syndiospecific down too late. The paper teeth in its paper paperboard from transmission, front gauge is not falling. If it is the former syndiospecific the wrong time, adjusts the control cam to advance a fall. If it is mutual pin mechanism does not work, then carefully check the interlock mechanism.
??3 swing pass all teeth look than before the cap with the distance between the transmission and paperboard. In this case the handover, the paper will be wavy, wave shape to further increase will cause paper break.
??The 4 gripper teeth and the prequel film between the handover is not suitable. Its reason and similar.
??5 the paper teeth in its paper quantity is too big. The paper in the transition process, to its mouth at the paper can not in the plane the handover is completed, thereby tearing paper. So in the circumstances allow, should minimize the paper in its most.
??The handover of the 6 teeth roughness is too big. The handover process appear uneven teeth pad, thereby the paper individual body parts appear the wave form.
??7 foot pressure and nozzle of paper with inappropriate. So the paper after the tear.
??The 8 gripper suction nozzle and the ground level roller transfer between inappropriate. Transpired between them should be in the common speed for long time, but due to mechanical wear, their interaction will change, appear thereby steal phenomenon of paper.
??9 transmission board and other parts of the paper form of mutual interference, thereby allowing the paper tearing performance. Exclude the interference of components.
??10 teeth on-off mechanism of inaccurate time. As a result of gripper opening and closing time, so that the paper could not in the ideal state transition. Readjust the open-close gripper mechanism.
??The 11 paper on the roller sports. Due to the centrifugal force, the rear end of the paper to outwards, especially in the paper collecting roller exhibited the most severe mutual. To these may form the interference components carefully regulated.
??12 delivery chain too easily cause paper tearing mouth. To tension the chain.
??The 13 paper in all parts and other components to form the mutual interference. So that the paper surface scratch.

??Ibuonline discount car electronics teach your automobile repair clever disassembly
??Car repair on difficult the demolition surfaces or refitted, and without the use of special tools or inconvenience removable parts, as long as the proper way, the process is reasonable grasp a "clever" word can do neither damage the parts can successfully disassembly. Here are some very simple and practical method.
??Disassembly of the steering wheel steering wheel fixed firmly improper demolition methods, time-consuming and laborious, but also easy to damage the steering wheel. In this regard, the left hand holding the steering wheel and forced to pull up, right hand hammer the steering wheel of the 180 (ie, the left-handed counterparts) at the mold beam (prior to package some soft material, to prevent injury the steering outer surface) parts, general the next, just a few, you can successfully remove the steering wheel.
??Take transmission bearing outer race transmission shaft front bearing broken bearing outer race to stay in the crank end of the bearing hole, some with gas cutting methods such as the demolition of not only the laborious time-consuming, but it is also easily damage bearing holes. The better approach is: find a wastegate valve head is too big, grinding (grinder should remain a small part) to be able to enter the bearing bore can. The edge of the valve head (no grinding at) are bearing the side of the outer ring, hand hammer the lateral percussion valve stem, the valve edge to the bearing outer ring ejection.
??Take the valve seat First, the welding method, suitable for cast iron cylinder head (puller). Taken a wastegate, processing to its head, so that the diameter slightly smaller than the size of the valve seat solitary. The valve stem in the valve guides and valve seat spot welding lap welding. At this point, after spot shrink force the valve seat ring contraction, as long as the hammer strikes the valve stem end of the valve seat will emerge. The two heating Law applies to the aluminum cylinder head. The cylinder head into the basin, adding waste lubricating oil, heated to boiling quickly removed, gently pick up the seat will emerge. Such to prolapse difficulties leveraging available screwdriver, etc., will successfully emerge.
??4. Inlay valve seat insert valve seat preparation work (the amount of interference, fine roughness should be consistent with the provisions of, cold shrink valve seat or thermal expansion seat bearing hole) after quickly valve seat flat valve seat on the Order of the hole to insert the models wastegate valve guides and valve head can be struck with a hammer. In this way, the valve stem can play a guiding role in the valve guides, valve head and valve seat contact uniform, reliable, and to ensure the smooth seat inserts into.
??5 refitted refitted air pump piston air pump piston, iron clamps, if done well, will appear the phenomenon of damage to the piston rings. In this regard, the desirability of the two rod bearing, with its grip piston rings with a hammer to gently poke piston into the cylinder. This method is applicable to various air pump piston refitted. Selection of tiles, you should pay attention to the The tile inner diameter should be slightly smaller than the piston diameter.
Pump water seal assembly pumps switch to graphite water seal, more and more, such as Dongfeng, liberation car. This water seal rubber ring is slightly larger than the pump impeller housing bore size 1mm - 1.5mm, assembly, the slightest mistake will lead to the rubber ring is pushed bad, even crushed graphite circle. Installation water seal separated from the first thin coat sealant, and then put into rubber circle outside the impeller Order of the hole, then smooth graphite ring pressed into the rubber circle. This method does not appear damaged water seal or leaking problems due to improper assembly

??Notebook batteries sold separately on the market in addition to expensive original battery, as well as sales of the great non-original battery. Non-original battery, compatible with both good quality brand batteries, assembled battery, batteries and counterfeit battery replaced core, the consumer must be a distinction.
??Security original batterybatteries & power supplies
??The biggest advantage of laptop original battery the monitoring protection circuit well, the batteries better quality, the quality is guaranteed. Although lately, some brand notebook series of fire due to battery reasons, but the overall look at the quality of the original battery is quite good. Of course, the drawback is the price of laptop original battery, its prices are generally compatible battery twice to three times or more.
??The most cost-effective high-quality compatible battery
??The laptop's original battery high price to be prohibitive, so many laptop users will look into the compatible battery. There are a variety of notebook compatible battery on the market, both small workshop production, also regular domestic manufacturers, as well as foreign brands of compatible batteries.
??In general, large production compatible battery with original battery performance, quality, security comparable. Compatible batteries are generally larger manufacturers have adopted the brand notebook original IC chip and high-quality batteries manufacturing, some even at the cost of the original laptop battery compatibility testing, such as "Teng Rui laptop battery by the original laptop test. Half or even lower quality compatible batteries generally have all the protection features of the original battery, and stable performance, the use of time is relatively long, there is not much difference in the actual performance of the original battery, the price is typically only original battery.
??Small workshop production of compatible batteries, of course, can not be compared with the large production, the small workshop production of the battery due to cost or technical constraints on battery safety protection design larger factory products a lot less, and will be saved compatibility testing procedure in order to save costs. Security point of view of compatibility, do not suggest that you select such products, although these products more attractive price.
??3. Careful of counterfeit batteries and change cell battery
??Laptop battery market there are two other products: counterfeit batteries and change cell battery. Counterfeit batteries greatest harm is low security, the counterfeit battery generally lack the protection circuit, and the poor quality of such products using the batteries, and some also use a no-name batteries, quality and endurance capacity is far less than the original battery. Therefore, the use of counterfeit batteries ranging from short life time, the problem can not be charged, appears leakage, explosion and other issues.
??Is some counterfeit notebook battery for the core battery, after the failure of the original battery batteries, some businesses through self change batteries for the original battery "new", this change generally have original cell battery protection function of the battery, how the quality depends on the quality of the batteries, of course, if the batteries with old batteries or inconsistent with the original batteries specifications, often there is a great security risk.

??Ibuonline automotive electronics suppliers teaches you how to judge the burning oil
??First said vehicle adding oil more or less will be consumed, but was not obvious problem. Ibuonline automotive electronics suppliers analysis, every 5000 kilometers 1 liters of oil consumption is belong to the normal situation, exceed this level must pay attention, to see if these circumstances appear.
??The exhaust pipe is black
??The first exhaust pipe inner wall wipe clean, wipe again a week time, if found in the exhaust pipe is black, said vehicle with burning oil phenomenon.
??The morning cold start when the blue smoke
??The morning cold start to observe the exhaust outlet, has just started if the exhaust pipe out of the blue smoke, it shows vehicles burning oil, the best two people cooperate to finish, one to start the vehicle, another person is responsible for the observed. Because the blue smoke for a short time, but only when the vehicle is placed for a long time will appear.
??The throttle when the blue smoke
??When the vehicle is in rapid acceleration or autochthonous banging accelerator when blue smoke phenomenon, but idling no, this case illustrates the vehicle burning oil, and has been more serious, should as soon as possible repair.
??The oil injection port blue smoke
??If the vehicle is in addition to the exhaust port, the oil injection port also began to take the blue smoke, the symptoms have arrived late, burning oil, the situation is serious, need to see a doctor as soon as possible, so as not to cause more damage.
??A cylinder seal is caused by the main reason of burning oil. Is mainly the fit clearance between the piston and the cylinder wall is too large, the piston ring sealing the improper installation or worse, on the cylinder wall of the oil into the combustion chamber, the phenomenon caused by burning oil.
??As far as possible the selection of good quality oil, automobiles may be appropriate to increase the viscosity of the oil cylinder piston, the sealing, long time use of mineral oil, synthetic oil was also easy to cause the sealing condition. Ground check oil gauge, regular replacement of oil and oil filter, oil filter replacement of genuine spare parts, choice of raw plant oil, can effectively avoid the phenomenon of burning oil.

??Ibuonline custom pcb manufacturer share appear ink lever solution
??Water, the ink is printed in the direction of the axis ( or transverse ) appear on the line or line. Water is as more water to cause ink not printed on the printed or too little; the ink line is caused due to the ink printing ink too much. Water, ink causes more, but also very complex. The following custom pcb manufacturer from different angles have a simple analysis of the reasons and eliminating methods.
??1 water roller pressure is too large. Because the water roller pressure is too large, in contact with the printing plate impact is big, cause water roller impact position on both sides of the water than the other parts of the surrounding water. Water roller slewing ring, water large parts of contact with the plate, causing the ink of diminished capacity, thereby forming a water bar. This should reduce the water roller pressure.
??2 water roll round. Because the water roll round, some place, some local low. High places is in contact with the printing plate will be generated when the sliding, thereby causing the water to swim product, forming a water bar. Replace the water roller.
??3 roller pressure is too large. The reason analysis of the same 1, is simply the impact on both sides of the ink quantity increases, thereby forming the ink.
??4 roller not round. The analysis of the 2.
??5 printing pressure is too great. As the printing pressure is too great, drum in the gap and a notch when converting the impact is too large, resulting in cylinder vibrating, so water, roller and a printing plate cylinder surface also impact, resulting in water, ink. The solution is to reduce the printing pressure.
??6 roller gear wear or the processing precision is too low. The accuracy of the gear is destroyed, the roller in the rotary process will appear inhomogeneity, so water, inking rollers and plates between the relative sliding, formation water, ink company. This time should replace the freighter or change gears meshing position.
??Water, ink once, the consequences are very serious, and should identify the reasons, and to the exclusion of.

Ibuonline printed circuit board manufacturer, exclude the application of the ghost in the machine malfunctions

By tingyuya

??Ibuonline printed circuit board manufacturer, exclude the application of the ghost in the machine malfunctions
??Ghosting is to appear in the printed products on two or more of the same blot, and its location right near. Automotiveried ghosting troubleshooting is to find the factors blot dislocation printed circuit board manufacturer.
??1 plate loose. Due to loosening of the printing plate, the position of the printing plate in the printing process can not be maintained constant, thereby twice blot transferred to the printed products on the old and the new position is not the same, and thus appears on the printed sheet ghosting. Re-clamping the printing plate, the circumferential direction, steering both sides of the screw to be in a working state, so that the version of the clamp and the relative position of the printing plate cylinder of the printing plate can remain unchanged; the automotived edition gap adjusting EDITION clamp to ensure that the printing process the same plate with the version of the relative position of the clamp; combined pressure of the mounting plate, so that the plate can be closely surrounded on the plate cylinder.
??. Blanket loose. As the blanket loose twice a position in contact with the plate (or impression cylinder) process is not the same, leaving the old and the new imprinted on the blanket, bound to transfer to the sheet ghosting. Clamp automotived mounted rubber blanket position is incorrect, reinstall the automotived, to ensure that in close contact on the plug on the blanket with clips and screws should be tight the middle, after tight on both sides, which prevents the blanket intermediate swim plot; rubber cloth tensioning force is too small, rotating worm agency reported hand blanket tension; blanket under the more uneven pad, caused some local rubber Jacobsson, blanket tight in some places, replace the gasket.
??3 of the paper on the impression cylinder slides. After the completion of the first-color printing in the multicolor printing sheet into the second-color printing, since the imprinted on the sheet is not dried completely in contact with the second color rubber City, again the printing side of the first color is transferred to the second The color on the blanket. If the position of the paper has changed, while the other parts are also in good working condition, the follow-up on the sheet, the first color blot should be the first color with the second color on the blanket blot completely overlap, because no ghosting; otherwise will produce ghosting. Dental films of the pressure on the impression cylinder is too small, increase the pressure of the dental film; severe dental pad wear on the impression cylinder, replacing the dental pad; the impression cylinder instigate paper amount is too little to adjust the rules to increase the amount of bite paper; printing too much pressure, reduce the printing pressure; ink viscosity is too large, plus the varnish or withdrawal viscosity to reduce the viscosity of the ink; thick full version, and replaced with a soft liner.
??4 paper deformation. The paper surface is uneven, the the paper moisture will cause the old and new imprinted do not coincide. Joint pressure (Sheung Shui can use the machine, but not on the ink) take the paper, so the paper after a decision imprint, basically flat state. And because itself has absorbed a certain amount of water, the possibility of re-swelling of much smaller.
??5. Drum string action. The plate cylinder, blanket cylinder, and other transfer cylinder moving string will cause the old and new blot not coincident, thereby generating a ghost. Automotiveefully check these the drum axial eye position device, inappropriate realignment, the general string Momentum controlled within 0.03mm.
Forum layout is unreasonable. Field change and mesh blocks should be properly arranged, the general should make it the axial distributed as evenly as possible, so ink viscous forces along the axial evenly distributed, thereby reducing the possibility of paper sliding.

The Ibuonline automotive electronics to share chassis system maintenance and repair strategy
Away from the repair point, the automotive breaks down, then it is a headache. Prepared no suffering, with the automotive in the normal should pay attention to the maintenance of the automotive automotive electronics.
Away from the repair point, the automotive breaks down, then it is a headache. Prepared no suffering, with the automotive in the normal should pay attention to the maintenance of the automotive.
It comes to automotive maintenance, chassis automotivee most likely drivers have ignored, but the importance of the maintenance of the good and bad in the winter or slippery weather chassis is quite clear. In the winter to the conservation of the chassis is necessary to completely do chassis cleaning and anti-rust treatment. Must first conduct a thorough cleaning of the chassis, the chassis on the dirt too much, but also spent oil cleaning agents to wash it again, so that the chassis exposed highland "Tomorrow", such antirust automotivee can begin. In the professional beauty shop, rose to the automotive the lifting rack chassis cleaning, wipe longer antirust automotivee. In the middle, it should be noted that after cleaning, be sure to wait until the water dry on the chassis can rust automotivee. During automotivee, be sure to maintain a uniform spray deposited coating, anti-rust coating a uniform layer retain lasting. For 5-10 minutes to dry naturally, be completed before chassis rust treatment considered complete.
Professional automotivee of the chassis done, does not mean foolproof, of which there is a misunderstanding, it is often people order the automotive will automotive itself flush, which often add some detergent, do not use alkaline Note cleaning agent? washing powder? washing the body and chassis, otherwise it will affect the anti-corrosion effect and shorten antirust Time.
Recommend that you go to the professional beauty shops do the automotiveds automotivee, a simple way to test out: finish the antirust automotivee chassis in a high pressure water jet rinse after almost not hanging drops its quality, this effect on behalf of genuine automotivee before they can play a very good rust protection effect.
Automotive chassis mechanical damage emergency well-
When the automotive in the field or away from the repair site encounter chassis mechanical damage, for different fault conditions, you can take advantage of the following first aid drive the truck to the repair conditions.
Brake wheel cylinder leak brake or wheel cylinder pipe broken in the slave cylinder pipe joints with iron, copper to be a small cushion the pipe blocked, and then tighten the screw, or the fracture folder flat, curl plugging, the wheel can not afford to brake used as. But to do so may result in unilateral braking, pay attention to safety when driving.
Shortage of brake fluid, brake master cylinder used alcohol or liquor instead of water can be used instead of special circumstances. The brake cup is made up, and will be made up of the cup on the hot water and soak for 10 minutes to 20 minutes, remove the oily ingredient on the cup, so that you can make a cup size to recovery Plateau.
The clutch friction plates ablation skid ablation less severe friction plate, flip. Such as ablation serious, available cotton or canvas several layers, with a wire or wire through the hole in the steel, it is fixed. Driving a vehicle should be started smoothly, the rapid shift action.
A broken tie rod ball joint in the bumper or other place does not affect the running, remove a screw similar to the total length of the ball joint to replace a broken ball joint, knuckle arm fitted with nut, screw exposed part of the rivet with a hammer. The triple axis automobile differential gear damage, such as damage to any one, can be the bridge drive shaft and axle shafts, the rear axle differential remove, continue driving. If the damage to the front differential, hub splice trays remove continue driving.

Ibuonline printed circuit board manufacturing services to summarize 8 recognition method of machine fault

By tingyuya

??Ibuonline printed circuit board manufacturing services to summarize 8 recognition method of machine fault
??On some troubleshooting methods are briefly introduced in the paper. But for machine fault, is more important to use what method to identify it. Machine fault variety, and is often a result of more fruit, a fruit because or multiple causes multiple effects. So how to accurately master the machine fault causes and results on the association between is to machine fault identification purpose.
??1 causal graph. Causality diagram is the cause and result among all possible relationship graphically linked, so look simple and clear.
??Other faults in the short form table may also reference picture, short form table has the advantages that the causes and results of the intersection between the.
??2 reference test method. The machine all parts are at the base in the form of linked, so if we can find the absolute baseline and relative to the baseline, then according to the reference graph can test the correspondences between them, such as with a standard state inconsistent, should be adjusted. A machine base is divided into two general categories: reference position and time reference. Grasp the essence of relationship, many fault will easily excluded.
??3 substitution ( exclusion ). Due to causes and outcomes between complexity, it is difficult to fault identification. In order to accurately identify the fault source, should be required to first rule out the fault source, troubleshooting an effective method is to replace the law. Replace consistent means that its not the fault source, such as change, show that it is probably the fault source ( there are of course not rule out other sources of failure ).
??4 symmetry principle. Symmetry principle is machine installation debugging and troubleshooting of a very important method. Symmetry principle content has been described by several faults, the following examples symmetry principle using method.
??5 visual method. Through visual observation rollers on the surface of the water, if the roll reflective, it indicates that the water in large. There are many faults can be visually eliminate the non fault source.
??6 ear method. Through the analysis of the internal ear machine whether there is abnormal sound, if there is abnormal sound, will be down to check, this method can be used to find no obvious fault.
??7 touch method. Through the touch can check component flexibility or air suction size, the method is particularly applicable to check the force closure mechanism hidden fault.
??The 8 signal analysis method. Through the sensor, picking up machine vibration signals, and then use the computer analysis and processing, find out the fault source. Using this method the best collection of new, old two kinds of signals, so as to compare analysis.
??It describes the troubleshooting the commonly used method, of course, there are other methods, when troubleshooting should take these methods, in order to select a troubleshooting optimal path.

Ibuonline car electronics teach you the techniques of car waxing method

By tingyuya

??Ibuonline car electronics teach you the techniques of car waxing method
??Free passage during the National Day this year, the car, many car owners choose traveling by car travel, returned from vacation, 4S shop after-sales service at waiting in a long queue, many car owners anxiously awaiting maintenance. In fact, some maintenance projects own hands to save the provincecar electronics.
??Tire pressure detection
??Recommended index: ? ? ? ? ?
??Checking tire pressure each time the 4S shop maintenance and long-distance detected before the necessary items, in fact, the operation is very convenient. The lid on the valve core unscrew the docking interface with the valve core air gauge, tire pressure table displays the current pressure for 1-2 seconds, the tire pressure to maintain normal circumstances the most appropriate in the 2.2-2.3.
??Replace the glass of water
??Recommended index: ? ? ? ? ?
??Few believe the friends have to go to the 4S shop to replace the glass of water, if you are unfortunate in this small number of people listed that you had better pay attention, this is a very simple task, when a small glass of water can not be ejected, purchase bottle glass of water, the engine cover is open, one marked with a cover glass and spray logo (often blue or yellow), poured into the glass of water can be found on the left side.
??Change wipers
??Recommended index: ? ? ? ? ?
??Wipers as a consumption accessories, there is no clear replacement time, but according to the situation of conventional vehicles, 2012 will certainly require replacement. Summer and winter, rain and snow erosion and temperature differences on the rubber material, wipers often appear abnormal sound, scraping clean, if so, that we need to replace the wiper.
??Current market wiper replacement is not uniform, but most of the models installed in the form of relatively similar central location with a clamp, press down gently slap wipers on the natural shedding, the operation is very simple. The installation method is the same case, the card slots are aligned with each other outside a pull to.
??Replacing the air filter
??Recommended index: ? ? ? ? ?
??Most car air conditioning filter replacement interval of 1 year, of course, different vehicle car environment need to be adjusted according to their own circumstances. The installation location led replaceable difficult outside except for a few models, many models of air conditioning filter can be replaced.
??Should first understand their own models of air conditioning filter position, we can from the vehicle owner's manual or at 4S shop to get an answer, general vehicle air-conditioning filter in the bottom of the center console (about indefinite). Replacement process is not difficult, is nothing more than open the shell of the filter is removed and replaced with new, different positions of each car air conditioning filter, disassembly methods and different, but it needs to be noted that the demolition of some vehicles to follow fixed order or need some tools and techniques, we can consult the maintenance master, in accordance with the formal way home to try more than once.
??Using this approach the owner can check regularly that accessories, simple clean when the air filter is dirty, but has not yet reached the replacement of the degree, but need to pay attention, avoid washing clean air filter or filter water easily soft rot. Purchase new accessories need to pay attention, try to choose a more formal parts store to make a purchase, otherwise fake not only a waste of money, is a loss of vehicles and car in order to save a few maintenance money to spend.
??Proposal
??The body waxing Mo own
??About waxing is good or bad has been the people debated topic, waxing can be dirty and oxide finish sanding, paint looks more bright. But at the same time from the theory waxing indeed be paint some damage, However, with the development of car beauty industry, now wax products has long been different from the past, also greatly reduced damage to the paint, not the use of substandard the products too frequent waxing, can damage the paintwork negligible.
??Reporters learned that regular waxing method is the first in a relatively enclosed indoor thorough car wash, waxing followed at the same location, and professional staff with professional polishing machine operation, while he waxed effect is necessary much worse, so is recommended for this project to go professional beauty shop or 4S shop owners.
??In addition, the replacement of oil operations in fact very simple replacement vehicle set up to let go of the old oil, there are certain requirements for venues and facilities, therefore not recommended to replace their own.
