What are the common faults and maintenance methods of vacuum oil filters?

How to solve the problem that the vacuum degree does not meet the technical standards?

There is too much water in the oil after filtration, and there is too much water vapor in the gas discharged from the vacuum

pump. This is a normal phenomenon and requires multiple filtrations;

Since the altitude of the place of use is different, it does not affect the change of vacuum degree under standard atmospheric 

pressure. Generally, the oil temperature should be increased to allow the water to evaporate;

The vacuum oil level in the vacuum pump is low, and a vacuum pump should be added;

Due to long use time, the vacuum oil needs to be replaced when the moisture content increases;

The seals at each connection are leaking and need to be inspected and repaired;

The consumable parts of the vacuum pump are worn and should be inspected and replaced.

How to solve poor oil control or no temperature?

The oil temperature is inconsistent with the thermometer, and the oil control needs to be adjusted;

If the heater is burned out, has an open circuit, or has mismatched contact arms, the circuit should be repaired and the heater

replaced.
