How to discharge the air in the hydraulic oil
Measures: wash the hydraulic system regularly, replace the hydraulic oil, prevent the oil filtrator and the dampers, etc. The high point of the system sets the air valve in the system when necessary. The system components shall be sealed to prevent air from entering the system. The backpressure valve is set back to make sure the back pressure is on the back and prevent the oil from being emptied. Self-absorbable pumps (such as plunger pumps) can cause a certain amount of positive pressure on the pump, such as the pump under the tank, etc. It is possible to avoid a sharp diameter change or a right-angle turn to avoid air separation from the system.
The simple method is to move the hydraulic cylinder back and forth in empty space.
Mixed with air in the hydraulic system of hydraulic actuators action will cause instability, with creeping, hydraulic components can cause cavitation, dry friction, shorten the life of hydraulic components, the noise is big. All effective elimination of air is the key to the stable operation of the equipment.
