Motor grader is one of the more common equipments in road construction. The accessories used in the maintenance process are also various, such as pumps, valve components, the cooperation clearance between the relatively moving parts and the working surface are small, hydraulic There are also many damping holes and slit-type control valve ports in the component. When the oil is polluted, the hydraulic pump will block, even scratch the mating surface, aggravate the leakage, or even jam the valve core, the component will malfunction situation. So how to prevent oil pollution of XCMG grader parts? The following editor will take you to learn together.
Motor grader accessories to prevent oil pollution:
1. The hydraulic oil used must be rigorously screened. When filling the hydraulic oil tank, it should pass through an oil filter of more than 120 mesh.
2. The hydraulic components should not be easily disassembled. If they must be disassembled, the parts should be cleaned with kerosene or diesel and placed in a clean place to avoid mixing of impurities during reassembly.
3. Regularly check the cleanliness of the oil and replace it regularly according to the working conditions. When replacing, the oil in the hydraulic system should be discharged as much as 40L.
Among them, the method using the outside circulation of the system is more operable. The method is to drain the waste oil from the fuel tank and radiator first, and then add new oil. Remove the oil return pipe into the oil tank, start the engine, and let the waste oil flow out completely from the oil return pipe.
Special emphasis is on the timely observation of changes in the oil level in the tank, and the safe height of the oil level should be ensured. When changing to new oil, the filter element of the filter should be replaced at the same time.
