What are the causes of uncleanness of vacuum oil filter

One: vacuum filter oil oil class does not meet the standard

Insulation oil, to achieve a high insulation value through high precision filtration, and most of the vacuum oil filter impurities on the requirements of much more extensive.

Two: viscosity of oil

The high viscosity oil cannot pass through the fine filter screen of the vacuum oil filter, so the vegetable can be filtered if it needs to reduce the precision. However, the operation cost of the vacuum oil filter will be increased if the precision filter screen is used because of the partial emphasis on the cleanliness of oil. Because the filter element is often blocked, it needs frequent cleaning and even replacement of the filter element.

Three: increase or decrease the axial pressure

Increase the axial pressure of the vacuum oil filter, so that the oil can pass through the screen quickly, but often will crush the filter element.

Iv. Oil filter hole is blocked

Vacuum oil filters need to be cleaned frequently in order to keep them clean. The connecting bolts of the motor and bracket of the vacuum oil filter should be checked frequently to avoid looseness. Always add lubricating oil to the compression screw nut.

Five: Oil capacity control

When the vacuum oil filter works, according to the oil filter capacity, after circulating filtration of 2 ~ 3 times of the oil filter amount, open the oil nozzle and take out the oil sample for test until it is qualified.

Six: The oil standard is too much

When the vacuum oil filter works, pay attention to the oil standard. If there is too much oil in the oil pan, open the oil return valve, drain the oil in the oil pan, and then close the oil return valve.
