Preventive measures for deterioration of excavator hydraulic oil

Basically, most failures of excavator hydraulic system are caused by hydraulic oil. If the hydraulic oil is not replaced for a long time, there will be blackening and viscosity reduction. It directly leads to abnormal wear of hydraulic system parts such as injection valve, multi-way directional valve and oil seal in the main pump of excavator. After a long time, the clearance between parts is too large and internal leakage occurs, which seriously affects the consistency and weakness of excavator action. This article will summarize some measures to prevent the deterioration of hydraulic oil for reference only.

1) Select appropriate hydraulic oil according to the selection standard of hydraulic oil specified in the operation manual of general excavator. According to the variety, brand and viscosity. When purchasing hydraulic oil, you must buy it in a regular brand store to avoid buying fake and shoddy products.

2) It is normal to control the working temperature of hydraulic oil during the use of excavator, which is generally about 50-80 degrees. If the temperature exceeds 90 ℃, the temperature is too high, and the hydraulic oil will deteriorate rapidly.

3) The hydraulic oil tank must be properly sealed to prevent pollutants from mixing into the hydraulic system.

4) Regularly check the condition of hydraulic oil, clean the filter element and oil tank, and replace the contaminated hydraulic oil in time.

5) Pay more attention to check the sealing of pipeline interface at ordinary times. Check the joints and sealing devices between the hydraulic system pipelines and components. If any damage is found, it shall be replaced in time, and the joints of each pipeline shall be tightened.
