The hydraulic filter element removes iron oxide, dust and other magazines in the hydraulic lubrication system to prevent the hydraulic system from clogging, reduce mechanical wear and ensure the stable operation of the engine.
Under normal circumstances, the replacement cycle of the engine hydraulic filter element is the first 250 hours of work, and thereafter every 500 hours of work. The specific replacement time should be flexibly controlled according to the quality of the lubricant.
When the filter element pressure gauge alarms or indicates that the pressure is abnormal, it is necessary to check whether the filter is abnormal. If so, it must be changed.
When there is leakage or rupture or deformation on the surface of the filter element, it is necessary to check whether the filter is abnormal. If so, it must be replaced.
