Reasonable use of hydraulic oil is the essence of the hydraulic system of engineering machinery      

 

According to the working practice, the author makes a rough discussion on the maintenance of the hydraulic system of the construction machinery in the general working environment.

For mechanized construction enterprises, the technical status of construction machinery is good or not is the direct factor of the normal production of enterprises.

For hydraulic engineering machinery, the normal operation of the hydraulic system is a major symbol of its good technical condition.

Qualified hydraulic oil is the guarantee of reliable operation of hydraulic system, and correct maintenance is the foundation of reliable operation of hydraulic system.

Choose proper hydraulic oil

Hydraulic oil plays a role of transmitting 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.

The hydraulic oil should be selected according to the brand specified in the manual. When special circumstances need to be used, the performance should be the same as that of the original brand.

The different grade mix of hydraulic oil, hydraulic oil to prevent chemical reaction, change in performance. Dark brown, white, and the hydraulic oil is the smell of oil deterioration, can not be used.

Two. Prevent solid impurity from mixing into hydraulic system

The cleanliness of the hydraulic oil hydraulic system is life.

The hydraulic system has a lot of precision parts, some have a damping hole, some gaps. If solid impurities invade, it will result in the damage of the precision couple, the hairpin, the blockage of the oil path, etc., and endanger the safe operation of the hydraulic system. The general solid impurities intrusion into the hydraulic system are: hydraulic oil is not clean; refueling tools unclean; refueling and maintenance, maintenance careless; hydraulic components desquamation.

Only the correct use of hydraulic oil, to try to save cost, improve work efficiency.
