A vacuum pump is a device or device that USES mechanical, physical, chemical or physical-chemical methods to pump air out of a container to obtain a vacuum.
Generally speaking, vacuum pump is a device that improves, generates and maintains vacuum in a closed space by various means. In case of automatic tripping of vacuum pump. The reasons for tripping should be understood first, then the vacuum pump tripping fault should be solved, and then the problem of tripping should be eliminated.
The reasons of vacuum pump trip are as follows：
1. Motor load. Vacuum pump motor load current is too high at this time, such as more than one set of current electric control, vacuum pump will be tripped, brake, at this time for the vacuum pump in the normal phenomenon, adjustable high current protection cap to solve tripping phenomenon;
2. The vacuum pump is stopped for a long time. If the vacuum pump is stopped for too long, the motor load will lead to excessive temporary current.
3.on the two phase power vacuum pump motor, is not enabled three-phase power supply, can be connected to vacuum pump three-phase power supply, if the trip again ten hours also, brake, etc., or adjust the over current limit;
4. The exhaust port of the vacuum pump inhales foreign matter or impurities, the motor load, and the vacuum pump can be disassembled to check whether there is any internal fault, etc.
