Vacuum pump refers to the device or equipment that uses mechanical, physical, chemical or physicochemical methods to extract air from the container to obtain vacuum. Generally speaking, vacuum pump is a device to improve, generate and maintain vacuum in a certain closed space by various methods. Open the water pump reminder, if not used for a long time or failure will cause the vacuum pump can not start normally.

Common faults of pump failure to start normally:

1. Pump sticking

2. Oil pump wear or foreign matter accumulation

3. Blade stuck

4. Rust in pump chamber caused by water inhalation

5. The coupling is damaged (the motor is running normally, but the vacuum pump is not running)

6. Motor voltage discrepancy

7. Connection error

8. Motor error

The vacuum pump can not be started normally. It is considered that the cause of the failure or the location of the failure should be found out. It is also necessary to remove the inner cavity of the pump body for cleaning and inspection in time to prevent secondary damage at the pump outlet. If you don't know much about the inside of the vacuum pump, you should find a professional vacuum pump maintenance manufacturer for professional vacuum pump maintenance.
