What are the types and functions of filters? High pressure pipeline filter (A): Located on the outlet pipe of the pump, it has the function of protecting pollutants from entering the system. Therefore, the concentration of pollutants in the system can be controlled. However, because it is a high-pressure supervisor, it must be affected by the pulse and pressure of the pump, so the material and strength of the filter element should be carefully considered.1. air filter: Located on the fuel tank, it has the ability to prevent pollutants from mixing with air due to the change of fuel quantity in the fuel tank. Therefore, the filtering accuracy should have the same performance as the filter, and the capacity should be left with sufficient room to prevent the internal pressure of the tank from becoming negative pressure due to hole blocking, causing the hole phenomenon of the pump. Pay special attention when the surrounding environment is bad.2. high-pressure pipeline filter (A): It is located on the outlet
