The return oil filter is mainly installed on the return oil pipeline of the hydraulic system. Various pollutants such as abrasive particles generated by various hydraulic components during operation can be intercepted by setting the return oil pipeline oil filter to avoid returning to the oil tank again The allowable pressure difference of the oil filter in the return oil pipeline ranges from 0.3 to 0.5 MPa depending on different pressure levels. The accuracy is determined specifically according to the requirements of oil contamination level.
There are more factors to consider when setting up the return oil filter, and one important factor is hydraulic shock, especially when there are hydraulic cylinders and proportional valves upstream. Under high pressure, the directional change of the hydraulic cylinder and the sudden power failure of the proportional valve will produce a large instantaneous flow shock, which will cause great damage to the filter element of the oil filter. When designing and selecting the return oil pipeline oil filter, it is necessary to have a full understanding and strengthen the structure.
Return oil filters are mainly used in the metallurgical industry, textile industry, mechanical processing equipment industry, etc!
