The wiper talks about this component. Many people don't think it doesn't matter. It doesn't make a big difference. If you think so, it's a big mistake. The importance of the wiper is undoubted. It's very important. It is related to the driver's driving in the car. Vision, and the most basic requirement for driving a car is to require the driver to have a good view, which not only reduces the occurrence of vehicle accidents, but also protects the driver's personal safety. Here are some of the relevant knowledge about the maintenance and maintenance of the car wiper that Xiaobian has compiled for the riders. There are two types of wiper, one is the traditional intermittent type. This is the most common type of wiper, which varies from three to four. It is adjusted by the driver according to the rain and line of sight. The other is the raindrop induction. , used in medium and high-end models. Good wiper must have the characteristics of heat resistance, cold resistance, acid and alkali resistance, corrosion resistance, ability to fit the windshield, reduce the burden on the motor, low noise, strong water repellency, soft texture and no scratching of the windshield. Clear. Maintenance personnel recommend that the wiper be replaced once a year to ensure your driving safety. 7. Some people think that the longer the wiper blade is, the larger the brush area and the better the field of view. In fact, the wiper blade is not as long as possible. Although lengthening the length of the wiper blade can increase the range in which the field of view is visible, the burden on the wiper motor and the wiper bar is relatively increased. Of course, it is of course possible to lengthen it, but it must be ensured that it must not interfere with the normal operation of the wiper. 4. When using in winter, the hailstone on the surface of the windshield should be cleaned with an ice shovel to avoid burdening the wiper. Winter maintenance After the angle is set, the disassembly and assembly can be started. First, the rubber blade should be lifted with one hand in order to expose the wiper arm and the fixing hook of the blade. The wiper blade is removed as a whole, the lower hand laterally splits the rubber blade, and the other hand presses down the main bracket to separate the wiper blade from the swing arm. After that, the wiper blade can be taken as a whole. under. The above is some of the maintenance and maintenance of the car wiper that Xiaobian has compiled for the riders, so it is very important for the riders not to ignore the small components of this car.

2. Pay attention to whether the way the pole is connected to the wiper arm is matched. Because some of the arms are screwed to the rocker arm, and some are locked with a male snap.
3. Pull the wiper up and use your fingers to touch the cleaned rubber wiper to check for damage and the elasticity of the rubber blades. If the blade ages, hardens, and cracks appear, the wiper fails.
4. During the test, place the wiper switch at various speed positions to check whether the wiper maintains a certain speed at different speeds. Especially in the intermittent working state, it is also necessary to pay attention to whether the wiper maintains a certain speed during the movement.
5. Check the state of the wiper and whether the wiper strut has uneven swing or slip. If the following three conditions occur, the wiper is unqualified. First, the swing is not smooth, the wiper does not jump normally; the second is that the rubber contact surface and the glass surface cannot be completely adhered to each other, and the wiping residue is generated; the third is that the glass surface is in a state of water film after wiping, and fine streaks and fog are generated on the glass. Linear residue.
6. Pay attention to the abnormal noise of the motor during the test. In particular, it should be noted that when the wiper motor “squeaks†and does not rotate. This indicates that the mechanical transmission part of the wiper has rust or stuck. In this case, the wiper switch should be turned off immediately to prevent the motor from being burnt.
Maintenance guide
1. When using a wiper to remove dust from the surface of the windshield on a sunny day, be sure to spray the glass water and do not dry it.
2. There are other stubborn and hard dirt on the glass, which should be cleaned by hand. These things can easily cause the wiper blade to be injured, resulting in a wiper that is not clean. In severe cases, the motor of the wiper will also be affected.
3, car wash and daily cleaning need to lift the wiper blade, you must take the "back" of the wiper blade, gently put back when you put it, you can not bounce the wiper blade back.
To properly clean the wiper: especially sand, it is the culprit of wiper wear. If you do not pay attention to cleaning, it will cause the wiper to wear out.
Try to avoid high temperature exposure: The strong heat in summer will test the rubber material of the wiper, which will cause deformation or loss of elasticity in the long run.
2. Check your wiper blade for cracks or damage in a timely and diligent manner. If it is, replace it in time. Otherwise, the wiper blade will scratch the glass of your car; check each piece of wiper in time.
3. Avoid parking in the open air when you are not using the car for a long time. If the conditions are not allowed, set the wiper up to avoid freezing when the snow melts, so that the wiper blade is frozen with the glass.
4. After each use of the wiper, clean the icing on the wiper blade in time. And when you leave your car at night, place a towel between the wiper blade and the glass so that the wiper blade and the glass will not stick together when exposed or frosted.
5. If you go out early in the morning and find that the wiper is stuck on the windshield by snow water, do not rinse it directly with hot water. This will easily cause the window to burst due to temperature changes and the wiper deformed. The correct method should be to open the air conditioner to the hot air, and the blowing mode is the front windshield, and the wiper is naturally opened.
6. The wiper should be turned off and then turned off before parking. Some car owners forgot to turn off the wiper, and the wiper will automatically turn on when the car is started the next day. In this case, the wiper that is frozen is easily burned out. If you encounter heavy snow, if necessary, stop at night to lift the wiper blades to avoid freezing. [1]
Disassembly and Assembly Guide First of all, the wiper should be completely erected. In order to avoid damage to the windshield during disassembly and assembly, it is recommended that the owner put a cloth on the windshield when disassembling the wiper. Support the wiper to change the blade angle.
Next, change the wiper blade to an angle of 90 degrees to the wiper arm. Because the wiper blade and the swing arm are caught by the clip, it is easy to disassemble after being angled.
(1) according to the loading material can be divided into: Propane tank truck, propylene tank truck , dimethyl ether tank truck, ammonia tank truck , methylamine tank truck, acetaldehyde tank truck, etc.
(2) according to the process and the role of loading capacity can be divided into: LPG vehicles, liquefied gas transport semi-trailer, liquefied gas storage tanks. the liquefied gas storage tanks can be designed for two kinds there`s underground storage tanks and ground storage tanks.
