Differences between oil suction filter and oil return filter

Many people think that oil suction filter and oil return filter are one kind of the product, and there is no way to distinguish their differences. In fact, oil suction filter and oil return filter are two types of hydraulic filters. Let me talk about their differences here.

The oil suction filter is installed at the oil suction port of the oil pump to protect the oil pump and other hydraulic components and adjust the cleanliness of the hydraulic system. The oil return filter is to filter the pollutants generated in the system on the oil return pipeline before returning to the oil tank.

The difference between oil suction filter and oil return filter also includes the following points:
1. The filtering accuracy is different, and the accuracy of the oil return filter is higher than that of the oil suction filter.
2. The flow rate of the oil suction filter is selected according to the large flow rate due to different flow rates; The selection of oil return filter should be determined according to the peak flow of oil return.
3. The position is different, and the oil suction filter is placed on the upper part of the oil tank; The oil return filter is on the oil return pipeline at the end of the system, and it cannot be set in other places.
4. The functions of the oil suction filter are different. The function of the oil suction filter is to effectively control the pollution of the hydraulic system by avoiding the inhalation of general impurities, prevent the faults caused by larger particles of impurities entering the oil pump, and achieve the function of protecting the oil pump and other hydraulic components.
