Hydraulic Maintenance:
For mechanized construction enterprises, whether the technical condition of construction machinery is good or not is a direct factor for the normal production of the enterprise. As far as hydraulically driven construction machinery is concerned, the normal operation of the hydraulic system is a major sign of its good technical condition. Qualified hydraulic oil is the guarantee for the reliable operation of the hydraulic system, and correct maintenance is the foundation for the reliable operation of the hydraulic system. Therefore, according to my work practice, I make a rough discussion on the maintenance of the hydraulic system of construction machinery in the general working environment.

Select hydraulic oil:
Hydraulic oil plays the role of transmitting pressure, lubricating, cooling and sealing in the hydraulic system. Improper selection of hydraulic oil is the main reason for the early failure and durability decline of the hydraulic system. The hydraulic oil should be selected according to the grade specified in the random "Instruction for Use". When the substitute oil needs to be used in special circumstances, the performance should be the same as that of the original grade. Different grades of hydraulic oil cannot be mixed to prevent chemical reaction and performance change of hydraulic oil. Dark brown, milky white, odorous hydraulic oil is deteriorating oil and cannot be used.
