(5) Cumulative efficiency test When the life of filter element is measured by grainy analysis method, the test time when the pressure difference at the test end point is reached or the catch amount of pollutants is evaluated.
(6) Hydraulic pulse fatigue test The oil filter is affected by the fluctuating pressure under the engine cooling state during its use. During the test, the specified pulsating oil pressure is used to circulate 1000 times to determine the compressive resistance of the filter shell, sealing ring and filter element with high pressure fluctuation.
(7) Vibration and fatigue test After installing the filter assembly of the machine, add the resonance frequency and amplitude caused by the vibration surface of the modular engine or the installed structure, maintain the specified oil pressure, and cycle 10 million times to determine the performance without small leakage of oil traces or fatigue damage.
