What are the common problems of automotive electronic vacuum pumps?

Automotive electronic vacuum pump is an important part in modern automobiles, its main function is to generate vacuum, so as to provide normal work for the electronic control system, braking system, cooling system and so on. However, due to long-term use or improper maintenance and other reasons, automotive electronic vacuum pumps will also have some common problems. The following details the common problems and solutions of automotive electronic vacuum pumps:

1. Abnormal noise: When starting the car, abnormal noise of the electronic vacuum pump is heard, which may be caused by wear or loosening of the blades, bearings or other parts of the electronic vacuum pump. The solution is to repair or replace damaged parts in time.

2. Insufficient vacuum: When the electronic vacuum pump cannot produce enough vacuum, it will affect the normal operation of the brake system, resulting in brake failure. This may be due to electronic vacuum pump intake pipe blockage, poor seal or vacuum pump seal ring damage caused by other reasons. The solution is to clean the intake pipe or replace the sealing ring.

3. Excessive vibration: When using the automotive electronic vacuum pump, if you feel the obvious vibration is too large, it may be caused by the installation of the electronic vacuum pump is not firm or the parts are damaged. The solution is to check and adjust the installation position of the electronic vacuum pump, and repair or replace the damaged parts.

4. Electronic control failure: electronic vacuum pump is controlled by the vehicle's electronic control system, if the electronic control system fails or the connection line is loose, it will lead to the electronic vacuum pump can not work normally. The solution is to check the electronic control system, repair the fault or reconnect the line.

5. Power supply problem: automotive electronic vacuum pump needs a stable power supply to work normally, if the engine failure, battery voltage is insufficient or the power line is disconnected, it will affect the work of the electronic vacuum pump. The solution is to check the power supply problem and repair it in time.

In general, automotive electronic vacuum pumps may have some common problems in daily use, but as long as they are found and repaired in time, more serious failures or accidents can be avoided. Therefore, it is recommended that car owners regularly check and maintain the automobile electronic vacuum pump to ensure its normal work and ensure driving safety.
