< r The installation location and purpose of the Pall filter element. The filter element should be installed at the suction port of the pump. A surface oil filter is generally installed on the suction path of the pump. The purpose is to filter out larger impurity particles to protect the hydraulic pump. In addition, the oil filter The filtration capacity should be more than twice the pump flow rate, and the pressure loss should be less than. The filter element is installed on the outlet oil line of the pump. The purpose of installing the oil filter here is to filter out contaminants that may invade valves and other components. Its filtration accuracy should be ~, and it should be able to withstand the working pressure and impact pressure on the oil line, and the pressure drop should be less than .3. At the same time, a safety valve should be installed to prevent the oil filter from becoming clogged. The filter element is installed on the oil return line of the system: this installation plays an indirect filtering role. Generally, a back pressure valve is installed in parallel with the filter. When the filter is clogged and reaches a certain pressure value, the back pressure valve opens. The filter element is installed on the branch oil line of the system. Separate filtration system for filter elements: Large hydraulic systems can be equipped with a hydraulic pump and oil filter to form an independent filtration circuit. In the filter hydraulic system, in addition to the oil filter required by the entire system, a dedicated fine oil filter is often installed separately in front of some important components (such as servo valves, precision throttle valves, etc.) to ensure their normal operation. It is used to protect specific components in the hydraulic system. It is installed upstream of the components that need to be protected in the medium-pressure pipeline to filter out solid particles and colloidal substances in the working medium, effectively control the pollution of the working medium, and ensure the normal operation of the components. The hydraulic oil filter element is mainly made of stainless steel woven mesh, sintered mesh, iron woven mesh. Since the filter materials it uses are mainly glass fiber filter paper, chemical fiber filter paper, and wood pulp filter paper, it has high concentricity and can withstand large pressures. , good straightness, made of stainless steel, without any burrs, ensuring long service life. Its structure is made of single or multi-layer metal mesh and filter material. In specific use, its number of layers depends on the composition of the mesh. The number of meshes depends on different usage conditions and uses.
