4. Prevent air and water from invading the hydraulic system

To prevent air intrusion into the hydraulic system, at normal pressure and normal temperature, the hydraulic oil contains air with a volume ratio of 6%-8%. When the pressure decreases, the air will be free from the oil. Bubble breakdown causes the hydraulic components to "cavitate" and produces noise.A large amount of air entering the oil will aggravate the phenomenon of "cavitation", increase the compressibility of hydraulic oil, work instability, reduce work efficiency, and have adverse consequences such as "crawling" of the executing elements.In addition, air also oxidizes the hydraulic oil and accelerates its deterioration.The following points should be noted to prevent air intrusion:


(1) Air in the system should be excluded according to the random "Instructions for Use" after maintenance and oil change.


(2) The suction opening of the hydraulic oil pump must not expose oil, and the suction pipeline must be well sealed.


(3) The seal of the drive shaft of the oil pump should be good. When replacing the seal at this place, the genuine "double lip" oil seal should be used instead of the "single lip" oil seal because the "single lip" oil seal can only be used for one-way sealing and does not have the function of sealing.
