Structural strength of oil return filter
(1)Axial stiffness: When the filter element is subjected to the axial load standard of the industrial process file, it should not deform and damage.
(2) Flattening rigidity: When the filter element withstands the ultimate pressure drop of the industrial process file standard, it should not deform 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.
