Lift for mechanized construction enterprises, the technical condition of construction machinery is a direct factor of normal production. As far as hydraulic transmission engineering machinery is concerned, the normal operation of hydraulic system is a major sign of its good technical status. Qualified hydraulic oil is the guarantee of reliable operation of hydraulic system, and correct maintenance is the fundamental of reliable operation of hydraulic system. Therefore, according to the work practice, the maintenance of hydraulic system of construction machinery in general operating environment is roughly discussed.
Selective hydraulic oil
Hydraulic oil plays the role of transferring pressure, lubrication, cooling and sealing in hydraulic system. Improper selection of hydraulic oil is the main reason for early failure and durability decline of hydraulic system.
Prevent impurities from mixing
Clean hydraulic oil is the life of hydraulic system. There are many precision coupling parts in the hydraulic system, some have damping holes, some have gaps and so on. If solid impurities invade will cause precision couple pull, hairpin, oil channel blockage, etc., endanger the safe operation of the hydraulic system, general solid impurities invade the hydraulic system way is: hydraulic oil unclean; Careless refueling, repair and maintenance; Hydraulic components chip removal, etc.
