How does the air in the hydraulic system affect the work of the system?
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. Preventive 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.
Hydraulic system with air first will certainly affect the system pressure, the oil will be a bubble, the action of actuators is not stable, have crawl phenomenon, pipeline and equipment vibration, and produces air corrosion and dry friction to hydraulic components, affect the service life of the element.
Generally, cleaning of system on a regular basis, if necessary to replace the hydraulic oil, prevent oil filter and damping hole blockage oil separating out the air vent valve is set in the highest point of the system, can be in need of exhaust, systems, components of sealing good, as far as possible to prevent air, what impurities to enter, on the back to oil set back pressure valve, the oil return has a certain pressure, to prevent oil, oil unloading of oil pipeline and avoid excessive right-angle turn, in order to avoid local stress, makes in the oil, air separation. That's about it. Think again.
