The most important thing for driving when it is raining is that the drivers sight must be clear. The wiper on the car can timely scrape the rainwater on the windshield to ensure that the driver can see the road conditions clearly.This is an important issue related to driving safety.Therefore, the wiper must choose good quality brand products.Generally speaking, the life of the wiper is one year, and the life of the boneless wiper may be extended to a certain extent, but there are few wiper that can be used for more than two years. So how long do you know how long to change the wiper?
Type of wiper
There are many types of wiper. Common wiper, boneless wiper, manual adjustment rainwater, speed sensing rainwater, rainwater brush, etc. The characteristics and applications of various wiper are given. Experts give the following introductions.
Ordinary wiper: It is currently the most common type of wiper. It is mostly equipped with low -end small displacement and old models. The price is cheaper and convenient for replacement.
Boneless wiper: At present, the popular configuration of mid -to -high -end models uses more high -quality rubber materials. It has good scraping effect. At the same time, it also has the characteristics of mute, sunscreen, and corrosion, which has a longer service life.
Manual adjustment rainwater: Traditional intermittent rainwater, you can manually select the wiper speed gear according to the rainfall. It is mainly equipped with old and low -end models. The price is relatively low.
Smooth -sensitive rainwater: It can adjust the rainwater to swing speed at any time according to the speed of the vehicle speed, which has the characteristics of convenient and high safety.
Rainfall sensing rainwater: High -tech products, can automatically induced the amount of rainfall, control the wiper swinging speed, relatively intelligent, simple operation, more expensive cost, mainly equipped with high -end models.
Wiper replacement
Generally speaking, the life of the wiper is one year, and the life of a boneless wiper may be extended, but few wiper can be used for more than two years.After summer exposure and cold in winter, the rainwater bar will be aging and cracking. When using a wiper, it is found that there are residual stains, stripe marks, jitter and abnormal noise on the glass, indicating that you need to change the wiper.
1. If the wiper has been used for 1-2 years, then it is recommended that you replace it in time. At this time, the wiper adhesive strip has been aging after a year or two.
2. Judging the wiper can scrape the rainwater on the front glass, especially after the rainwater wiper is scraped when the rainwater is rained.
3. Gently lift the wiper to observe whether the rainwater strip is cracking. If the cracks or folds occur, you need to replace it
4. Whether the wiper is noisy during the work, if the noise is getting bigger and bigger, you need to replace the new one
5. Due to the high frequency of using a wiper in the rainy area in the south, the replacement cycle can be shortened according to local conditions to ensure that it can be scratched and clean new vision in the rain.
Wiper fault treatment
Subtititive maintenance of wiper action
The main reasons are: wiper scraping slices and dirt on the surface of the glass; the power supply voltage is too low; the wire is poor; the motor bearings and the deceleration are poorly lubricated; the motor carbon brush is poor with the rectifier; the carbon brush spring is soft and so on.Maintenance method: Wash and scrape the scrape and oil pollution of water; appropriately increase the output voltage of the motor; check the connection of the wires; repair the rectifier; maintain the motor bearing and reducer, add lubricating oil, fat, etc.
Sudden maintenance of the wiper
The main reason is caused by the tie rod card in the reducer shell, or the fuse melting.
During the maintenance, the deceleration agency must be disassembled and the cause of the stuck is found to move the lever freely in the shell.It is found to be excluded after the cause of the road break and short circuit.
