The maintenance method of hydraulic oil filter element is as follows:
1. Drain the original hydraulic oil before changing, check the oil return filter element, suction filter element, pilot filter element, to see if there are iron filings, copper filings or other impurities, if there are hydraulic component failures, clean the system after maintenance .
2. When changing the hydraulic oil, all hydraulic oil filter elements (return oil filter element, oil suction filter element, pilot filter element) must be replaced at the same time, otherwise it is equivalent to not changing.
3. Identify the hydraulic oil label. If hydraulic oils of different labels and brands are not mixed, they may react and deteriorate and produce flocs. It is recommended to use the specified oil for the excavator.
4. The oil suction filter element must be installed before refueling. The nozzle covered by the oil suction filter element directly leads to the main pump. The ingress of impurities will accelerate the wear of the main pump, and if it is heavy, the pump will be used.
5. Refuel to the standard position. Generally, there is an oil level gauge on the hydraulic oil tank, please check the level gauge. Pay attention to the parking method, generally all the cylinders are retracted, that is, the forearm and bucket are fully extended and landed.
6. After refueling, pay attention to the main pump to exhaust air, otherwise the whole car will not move temporarily, the main pump will make abnormal noise (air sonic boom), and the main pump will be damaged by cavitation. The method of exhausting air is to directly loosen the pipe joint on the top of the main pump and fill it up directly.
