WU-1000 80-J WU-1000 100-J WU-1000 180- 1) The filter element should be installed at the suction port of the pump: Generally, a surface-type oil filter is installed on the suction line of the pump. The purpose is to filter out larger impurity particles to protect the hydraulic pump. In addition, the filter capacity of the oil filter should be For more than twice the pump flow rate, the pressure loss is less than 0.02MPa.(2) The filter element is installed on the outlet oil circuit of the pump: The purpose of installing the oil filter here is to filter out pollutants that may invade valves and other components.Its filtration accuracy should be 10-15m, and it can withstand the working pressure and impact pressure on the oil circuit, and the pressure drop should be less than 0.35MPa.At the same time, a safety valve should be installed to prevent clogging of the oil filter.(3) The filter element is installed on the oil return line of the system: this installation serves as an indirect filter.Generally, a back pressure valve is installed in parallel with the filter. When the filter is blocked and reaches a certain pressure value, the back pressure valve opens.(4) The filter element is installed on the branch oil circuit of the system.(5) Separate filter system of filter element: Large hydraulic system can be specially equipped with a hydraulic pump and oil filter to form an independent filter circuit.Generally, in addition to the oil filter required by the entire system in the filter element hydraulic system, a special oil filter is often installed in front of some important components (such as servo valves, precision throttle valves, etc.) to ensure their normal work.
