In the eyes of many car buyers, wipers are the least technological and most easily overlooked items in auto parts. Unless it’s raining, the wipers are mostly a decorative design that no one pays attention to, but when it rains suddenly, I find many problems: the rain on the windshield can’t be wiped cleanly, or there is always a layer of oil-soluble Chemicals, or a trail of water droplets from the wipers. At this time, I thought of the teacher’s suggestion: there is nothing in the car that is unnecessary!
Once the wipers are dirty, what problems does it pose to safe driving? An old wet machine told the news reporter that the sight of the front windshield of the vehicle is related to safety. Whether the wiper can effectively eliminate the precipitation on the glass in rainy days is very important for the driver to give a bright line of sight.
Under normal circumstances, the wiper that meets the regulations cannot leave water marks on the glass. Because of the water mark reflecting surface, if driving at night, the water mark will reflect the light effect on the opposite side of the surface, affecting the driver’s sight; another situation is , The wiper can clean the water marks normally, but because the glass is usually not paid attention to cleaning, the glass will also cover a layer of oil and chemicals, when the wiper wipes water, the glass turns white and produces fog, and the vision is poor. In the end, the physical performance of the wiper is mainly reflected in two levels, because the wiper motor is damaged, either it is not working, or the speed can be changed, and it is easy to cause inconvenience. Nowadays, many vehicle wipers have a speed-adjusting function. The buyer can choose the speed according to the amount of rain, but once the speed cannot be changed, in case of heavy rain, the speed of the wiper is too slow to wipe the rain immediately, which will also cause the driver’s line of sight. Unclear, leading to safety hazards.
Whether the rubber part of the wiper is well maintained is not so much related to the actual effect in the work. The rubber has embrittlement problems, mainly manifested as brittle deformation, brittle cracking, cracking or deformation. reason. Most of the water marks left by the wiper are caused by the above reasons, so the rubber of the wiper should be carefully maintained.
No need to dry shave. Before driving on the road, some drivers want to remove the dust and dirt on the glass according to the wiper, and wipe dry without spraying water. If you want to remove the dust from the glass, it is best to sprinkle water first. You can gently extend the wiper several times, so that the glass is not scratched, and when the glass is wet enough, it is not easy to dry and damage the wiper rubber. Naturally, it is best to use a duster to remove dust and dirt from the glass first, and then repeat the above posture, because even if the glass is sufficiently wet, the transparent muslin on the glass will destroy the rubber of the wiper.
Prevent high temperature. This specifically refers to the exposure of the vehicle to the scorching sun, with the wipers close to the hot windshield of the vehicle, which in turn scald the rubber of the wipers. Therefore, it is recommended that riders park the car in a cool area on a sunny day. If the outdoor parking is unavoidable and parked under the sun, it is best to raise the wiper. Avoid oil. This problem is very easy to understand, because the oil on the glass is very easy to solidify into water droplets, in addition. In the same way, the windshield or wiper of the vehicle accidentally encounters oil stains, and it is not easy to wipe clean rain. Even though the wipers are placed on the windshield, it’s very easy to ignore them during routine maintenance. If there are oil stains on the glass, it is best to wipe the wiper and glass with glass cleaning fluid.
Regular maintenance. This is called preparation. When checking, put the power switch of the wiper on various speed positions to check whether the wiper guarantees a certain speed at different speeds; check whether the wiper lever shakes unevenly or leaks the wiper. Either of these two common failures can represent a damaged wiper blade. Then run the wiper, pay attention to whether its posture is stable, and whether there is a loud noise. If the noise is relatively loud, it means that the pressure of the wiper on the glass is too large, and appropriate adjustment must be carried out.
When the wiper scanner scans once or twice, check to see if there is any water on the windshield, and at the same time, check to see if there will be some scratches. If you see scratches clearly, it means that the scratches on the wiper are old and should be replaced with a new tape. Finally, check the wiper blade and touch the rubber sheet with your fingers to see if there is damage and the ductility of the rubber blade. If the blade is old, hardened, or cracked, it should be replaced immediately.
