Maintenance of lift hydraulic system

2017 / 02 / 14

Maintenance of lift hydraulic system For mechanized construction enterprises, the technical situation of construction machinery is good or not the direct production of enterprises can be a direct factor. In terms of hydraulic transmission of construction machinery, the normal operation of the hydraulic system is a good sign of its good technical condition. Qualified hydraulic oil is the reliable operation of the hydraulic system protection, the correct maintenance is the fundamental operation of the hydraulic system. To this end, I work according to the practice, the general operating environment in the construction machinery hydraulic system maintenance for a rough discussion. 1. Select the appropriate hydraulic oil Hydraulic oil in the hydraulic system plays a transfer pressure, lubrication, cooling, sealing the role of hydraulic oil selection is not appropriate hydraulic system early failure and the main reason for the decline in durability. The hydraulic oil should be selected according to the grade specified in the random "instruction manual". In case of using the substitute oil, the performance should be the same as that of the original grade. Different grades of hydraulic oil can not be mixed to prevent the hydraulic oil to produce chemical reactions, performance changes. Dark brown, milky white, smell the oil is metamorphic oil, can not be used. 2. Prevent solid impurities from entering the hydraulic system Clean hydraulic oil is the life of the hydraulic system. There are many precision coupling in the hydraulic system, some with damping holes, and some gaps and so on. If the solid impurity invasion will result in precision even pieces of injury, hairpin, oil blockage, etc., endangering the safe operation of the hydraulic system. General solid impurities to invade the hydraulic system
