The oil return filter in the hydraulic system refers to the filter used in the oil return of the system. After the actuator performs work, particle impurities and rubber impurities may be generated due to wear and tear of the equipment. If you do not want to bring in impurities in the oil, The fuel tank can only be filtered with a filter element or a filter in the oil return system.
The hydraulic oil return filter is installed in the oil circuit of the hydraulic system to remove metal powder and other mechanical impurities from the components of the hydraulic system to keep the oil circuit clean and extend the life of the hydraulic system. The low-pressure series filter also has a bypass valve. . When the filter element is not replaced in time, the bypass valve can automatically open to ensure the normal operation of the system.
Select the characteristics of the filter element:
(1) Axial rigidity: When the filter element is subjected to the axial load standard of the industrial process file, it should not cause deformation and damage.
(2) Flattening rigidity: When the filter element withstands the extreme pressure drop of the industrial process file standard, it should not cause deformation and damage.
(3) Pressure drop flow characteristic: The pressure drop flow characteristic curve of the standard filter element should be used in the industrial process file.
(4) Flow fatigue characteristics: Under standard flow and pressure drop conditions. The number of flow fatigue cycles of disposable filter elements is not less than 10,000 times, and the number of flow fatigue cycles of reusable filter elements is not less than 20,000 times.
