Equipment Hydraulic Oil Filter requirement

The hydraulic oil often contains particulate impurities, which will cause the wear of the relative moving surface of the hydraulic components, the sticking of the slide valve, and the clogging of the throttle orifice, which greatly reduces the reliability of the system. Installing a certain precision oil filter in the system is a necessary means to ensure the normal operation of the hydraulic system. The filtration accuracy of the oil filter refers to the size of the smallest impurity particles that the filter element can filter out. It is expressed in micrometers and can be divided into coarse oil filters (80 micrometers-250 micrometers) and ordinary oil filters (10 micrometers -40 micrometers) according to the accuracy. Micron), essential oil filter (3 microns-5 microns), special oil filter (1 micron).

Generally, the basic requirements for oil filters are: (1) It can meet the filtration accuracy requirements of the hydraulic system, that is, it can prevent impurities of a certain size from entering the system. (2) The filter element should have sufficient strength and not be damaged by pressure. (3) Large flow capacity and small pressure loss. (4) Easy to clean or replace the filter element.
