Method for diagnosing vacuum degree of vacuum pump

Conventional fault diagnosis method for vacuum degree of vacuum pump

The cause of vacuum failure is not unique, and our methods of detection is single, the entire system is only a piece of vacuum table, this table can only reflect the system's final pumping results, but does not reflect at a time on the process of each unit, for troubleshooting to Xu

More inconvenience, but also increases the troubleshooting time.

At present, the use of troubleshooting methods for the exclusion of the basic law, the steps are as follows:

1, to determine the accuracy of the vacuum meter;

2, to ensure that the system off valve without leakage;

3, if the fault is a manifestation of the phenomenon, you need to check out the entire system of external leakage;

4, if the failure form of the phenomenon of two, first check the parameters of steam, water and other energy media value is abnormal, without exception, check the check valve, without exception, as the system performance test, determine the performance of the level to which the pump has a problem, check the nozzle and the steam valve of the pump.
