How to Bleed Air When Changing Hydraulic Oil?

When changing hydraulic oil, the air will be discharged through the return line as the oil pump operates. Air enters the hydraulic pump mainly from the suction port, either due to a large amount of air bubbles mixed in the oil inside the tank or because the suction line is not sealed, allowing air to enter. Additional details are as follows: 1. Suction port leakage: If there are a large number of air bubbles in the tank, the suction port of the oil pump needs to be sealed. The selected hydraulic oil pump should meet the pressure and flow requirements of the hydraulic system, while also considering reliability, lifespan, and maintainability to ensure long-term operation in the hydraulic system. 2. Precautions to prevent hydraulic oil leakage during bleeding: If using a hose, ensure there is some slack. When bending the hose, the bending radius should be greater than the minimum bending radius. Avoid twisting during installation. Extend the hose length in areas with bending or vibration. Isolate the hose from nearby heat sources. Try to avoid 90° bends.
