The maintenance of loader accessories hydraulic cylinder is the maintenance of hydraulic medium and hydraulic cylinder. Hydraulic transmission has the advantages of simple structure, stable quality, high mechanical efficiency and easy automation. In order to maintain the hydraulic cylinder and reduce contamination and impurities mixed into the hydraulic oil:
?? during the use of the oil cylinder, the hydraulic oil shall be replaced regularly, and the system filter screen shall be cleaned to increase the service life. Each time the oil cylinder is used, it shall be fully extended and fully retracted for 5 strokes, and then run with load. This can exhaust the air in the system, preheat each system and reduce the air or water in the system, resulting in gas explosion (or charring) in the cylinder block, which will damage the seals and lead to faults such as internal leakage of the oil cylinder.
? temperature of control system. If the oil temperature is too high, the service life of the seal will be reduced. Protect the outer surface of the piston rod, reduce the damage of bumps and scratches to the seals, and often clean the dust ring of the dynamic seal of the oil cylinder and the sediment exposed on the piston rod. Dirt stuck on the surface of the piston rod that is difficult to clean enters the oil cylinder and damages the piston, oil cylinder or seal. Frequently check the connection parts such as threads and bolts, and find that they are loose and fastened. Frequently lubricate the connecting parts to reduce corrosion or abnormal grinding under oil-free conditions.
