How long does the standard stipulate the life of wiper?
Generally, there will be a description of the factory time and service life of automobile parts when they leave the factory. It is stipulated in China's standard regulations that after the wiper strip is removed, the wiper must have working ability after passing through the 150*10 fourth power; According to a paper, if we all drive for an hour in rainy days, it will be about 103 hours a year, and if we calculate it at 50 times per minute, it will be about 300,000 times a year. In this case, the life of a pair of wipers is about 5 years, and the wiper strip can be used for about 1 and a half years. But in fact, the wiper doesn't take so long. Generally speaking, the replacement cycle of the wiper is about one year, and the wiper strip needs to be replaced once every six months.
How to judge whether the wiper should be replaced?
When using the wiper, we should observe the scraping effect. If there are a lot of water marks on the wiper, it is not cleaned, and the wiper will make abnormal noise during use, and it will not be smooth when rubbing the windshield. These situations all show the problems of wiper deformation, aging rubber strip and insufficient wiper pressure, so we have to change the wiper. Wipers with slightly better quality can be used for one and a half years or two years if they are well maintained; If the quality is slightly ordinary, it can only be used for about half a year. In short, if it is broken, it will be replaced, which will not affect the driving in rainy days, so as not to threaten life.
Usage of automobile wiper
You can't use the wiper to clean the windshield without water. Dry scraping without water will damage the film on the wiper and the wiper motor. Do not use the wiper when it does not affect driving; You can't use the wiper to scrape the dust on the windshield, because the wiper is designed to scrape rainwater at the beginning. If you scrape dust, it will have the same effect as dry scraping without water, which will damage the wiper motor. Also, when there are foreign objects falling on the windshield, you should not use the wiper to remove them blindly, for fear that there are hard objects in the foreign objects, which may easily cause local injuries to the wiper and affect its service life, which is not worth the candle.
When there is a problem with the wiper, you should go to the repair shop to replace it in time to avoid heavy rain. The wiper is broken and you can't see the road ahead clearly. Driving in rainy days is safety first.
