What types of liquid filters are there?
High-pressure pipeline filter (A): It is installed on the outlet pipeline of the pump to protect the pollutants from entering the system. Therefore, the pollutant concentration of the system can be controlled. However, because it is a high-pressure main line, it is subject to the pulsation and pressure of the pump, so the material and strength of the filter element should be carefully considered.
1.) Air Filter: It is installed on the fuel tank to prevent pollutants from being mixed into the fuel tank with the air due to the change of the fuel volume of the fuel tank. Therefore, the filtration accuracy should have the same performance as the filter, and the capacity should have enough room to prevent the internal pressure of the fuel tank from becoming negative pressure due to hole blockage, causing the cavitation of the pump. Be especially careful when the surrounding environment is harsh.
2.) High-Pressure Pipeline Filter (A): It is installed on the outlet pipeline of the pump to protect the pollutants from entering the system. Therefore, the pollutant concentration of the system can be controlled. However, because it is a high-pressure main line, it is subject to the pulsation and pressure of the pump, so the material and strength of the filter element should be carefully considered.
3.) Oil Suction Filter: The filter is installed on the suction pipeline of the pump, and it filters out the residual pollutants in the oil tank and the pollutants entering through the air hole, which has the function of protecting the pump. However, in order to avoid cavitation in the pump, the melt blown filter element must pay full attention to the pressure loss, and generally use 100-200 purpose thick metal mesh or notch wire material. Therefore, it is not a filter that controls the contamination concentration of the system
4.) Return Filter: set on the oil return pipeline of the system, its function is to capture the pollutants generated or invaded in the system before returning to the oil tank. Therefore, it is the most effective and important filter to control the pollution concentration of the system. Although it is a low-pressure pipeline, pulsation or pressure shock may also occur according to the operating conditions of the transmission, so the material and strength of the components should be fully considered.
5.) High-Pressure Pipeline Filter (B): In the system, in order to protect the hydraulic parts that are particularly sensitive to pollution, this filter is installed, also known as the terminal filter. Therefore, it tends to have a smaller filtering granularity than other filters. Therefore, when using, choose a large capacity. In addition, the material and strength of the element should also be fully considered as in (A).
6.) Circulation Filter: It is located on the oil return road of the oil tank circulation. The capacity of the system is large, so it is often used when strict cleanliness is required. Even if the system is not working, the pollutants in the oil tank can be captured. Therefore, the efficiency of reducing the pollution concentration is the best. In addition, a cooler is installed, which has the advantages of simultaneous cooling and easy maintenance. However, special pumps and motors are required, and the cost is high.
