Precautions for oil filter operation

Precautions for oil filter operation

1. When the vacuum pump is working, pay attention to the oil displayed on the oil mark (the oil should be on the oil mark line). When the oil and water content of the vacuum pump is large, it should be replaced in time.
2. Always pay attention to the change of pressure gauge value. When the pressure value is ≥ 0.4MPa, clean the filter or replace the filter element.
3. The filter screen of the primary filter shall be removed and cleaned frequently to keep it clean, so as not to block, resulting in insufficient oil inlet or too high pressure.
4. Pay attention to whether the operation noise of vacuum pump, oil pump and corresponding motor is normal at any time during operation. If it is abnormal, it shall be eliminated immediately.
5. When the high-efficiency vacuum oil filter is not in use, drain the vacuum pump oil and inject new oil.
6. Before oil treatment, use a water absorber to suck out open water and impurities from the bottom of the oil barrel to ensure that the pressure resistance is above 10kV.
