Finding and solving the oil leakage of hydraulic system of vacuum oil filter

Search and solution of oil leakage in hydraulic system of vacuum oil filter

With the high pressure, precision and high performance of hydraulic system, the function of filter is more and more obvious. If the filter can capture the minimum clearance of particles is best, but it is best to set the limit according to the need, otherwise it will cause blockage, resulting in cleaning maintenance management trouble, too long time, cost increase, etc..

One of the most common failures of vacuum oil filter is oil leakage, which usually occurs in motor bearing seal, oil tank gasket and oil window of vacuum pump.

1. There are two oil seals on the motor shaft, which will cause oil leakage if there is aging failure.

2. There is a sealing ring at the junction of the adapter and the tank. Aging will cause leakage of the vacuum pump.

3. Oil leakage of oil window is caused by aging of adhesive between oil window and oil tank, or aging of oil window and rupture of oil window, which causes oil leakage of pump.

4. The felt pad on the adapter, when the oil absorption is full, the vacuum pump will also have oil seepage.

The solution to the leak is to replace shaft seals, aging oil Windows, felt pads and gaskets.
