When using hydraulic oil filter elements on a daily basis, be careful to maintain them frequently. How do you do the maintenance work?
1. Before replacing, first empty the original hydraulic oil, check the oil return filter, oil absorption filter, pilot filter to see if there are copper filings or other impurities. If there are impurities, there may be hydraulic components failure. , cleaning system.
2, identify the hydraulic oil label, different brands, different labels of hydraulic oil can not be mixed with each other, may react to produce impurities.
3. When changing hydraulic oil, all hydraulic oil filter elements (return oil filter, oil suction filter, pilot filter) must be replaced at the same time, otherwise it is equivalent to no change.
4, after adding the oil, pay attention to the main pump to discharge air, otherwise the light will temporarily no action, the main pump is abnormal (air blast), and the air pocket damages the main pump. The air exhaust method is to loosen the pipe joint directly on the top of the main pump and fill it up directly.
5, refueling to the standard position, the hydraulic tank generally has an oil level gauge, look at the liquid level gauge. Pay attention to the parking mode. Generally, all the cylinders are fully retracted, that is, the arm and bucket are fully extended and landed.
6. Before the refueling, the oil-absorbing filter element must be installed first. The nozzle of the oil-absorbing filter core is directly connected to the main pump. When the impurities are light, the main pump is accelerated and the pump is pumped.
