Maintenance measures For mechanized construction enterp […]
For mechanized construction enterprises, the good condition of engineering machinery technology is a direct factor for the normal production of enterprises. In the case of hydraulically driven construction machinery, the normal operation of the hydraulic system is a major indicator of its good technical condition. Qualified hydraulic oil is the guarantee for the reliable operation of the hydraulic system. Correct maintenance is the basis for the reliable operation of the hydraulic system. According to the work practice, a rough discussion on the maintenance of the hydraulic system of the construction machinery in the general working environment is made.
Hydraulic oil plays the role of transmitting pressure, lubrication, cooling and sealing in the hydraulic system. The improper selection of hydraulic oil is the main reason for the early failure and durability of the hydraulic system. The hydraulic oil should be selected according to the grade specified in the random "Instruction Manual". When the substitute oil is used in special cases, the performance should be the same as the original grade. Different grades of hydraulic oil cannot be mixed to prevent chemical reactions and changes in performance of hydraulic oil. Dark brown, milky white, odorous hydraulic oil is a metamorphic oil and cannot be used.
