AI Technical Summary

Technical Problem

Existing hydraulic actuator oil filling methods consume a large amount of oil, easily contaminate the oil, and are difficult to ensure full filling and air removal, posing safety hazards and being environmentally unfriendly.

Method used

Using an oil injector and pipe fitting, and taking advantage of the density difference between gas and hydraulic oil, the actuator is tilted and the air is expelled by repeatedly pushing and pulling the piston rod, thus achieving rapid and efficient oil injection.

Benefits of technology

It improves oil injection efficiency, saves oil consumption, ensures oil cleanliness, improves the operating environment, reduces costs, and avoids safety hazards.
