Prevents air and water intrusion into hydraulic systems
Prevent air from invading the hydraulic system. Under normal pressure and temperature, the hydraulic oil contains air with a volume ratio of 6%-8%. When the pressure drops, the air will free from the oil, and the burst of air bubbles will cause "cavitation" of the hydraulic components and generate noise. A large amount of air entering the oil will intensify the "cavitation" phenomenon, increase the compressibility of the hydraulic oil, cause unstable work, reduce work efficiency, and cause adverse consequences such as "crawling" of the actuator. In addition, the air will oxidize the hydraulic oil and accelerate its deterioration. To prevent air intrusion, the following points should be paid attention to:
(1) After maintenance and oil change, the air in the system should be removed according to the provisions of the accompanying "Instruction Manual".
(2) The oil suction pipe of the hydraulic oil pump must not be exposed to the oil surface, and the oil suction pipe must be well sealed.
(3) The seal of the drive shaft of the oil pump should be good. When replacing the oil seal at this place, the "double lip" genuine oil seal should be used instead of the "single lip" oil seal, because the "single lip" oil seal can only seal oil in one direction and does not have a seal. gas function.
