During the use of the vacuum pump, it is a common phenomenon that the pressure cannot meet the process requirements, or the ultimate vacuum deteriorates.
First, make a preliminary judgment on what caused it based on the on-site equipment configuration, pipeline connection, measurement requirements, etc.
Eliminate external factors (measurement regulation effectiveness, pipeline or cavity leakage, etc.), and then perform further inspections on the pump.
Common faults are
-
Failure of measurement method or regulation
-
External leakage
-
Failure of the anti-return valve
-
Exhaust valve failure
-
Pump oil is not suitable
-
The air inlet is contaminated
-
The pumping speed is too small
