Talk about the daily maintenance of hydraulic cylinders work content

Hydraulic cylinder seals often need to be maintained, overhaul, maintenance to extend their service life and seal performance. Piston is to avoid the main components of the hydraulic oil leakage, in the inspection process can be run in accordance with normal operating specifications of machinery, and then operate the reversing valve so that the piston extends to its position, which is in the ascending state, the pipeline is removed from the oil port, to observe whether there is a leakage of hydraulic oil. If the leakage of hydraulic oil is found, it is necessary to check the wear and tear of the seals and the piston and the piston rod between the seal is intact.

Secondly, if the inspection results show that the seals and guiding bearing ring there are different degrees of damage, it should be based on the original seals or guiding bearing ring structure form, choose the same specification of the material for production and replacement, so as to reduce the seals and the sealing surface of the thickness of the film, so as to avoid the reoccurrence of the leakage of hydraulic cylinders.

Seals sealing can cause oil leakage, which makes the mechanism movement is not stable, reduce the volumetric efficiency, pollution of the environment, the seriousness of the establishment of the pressure, the system can not work. Therefore, in daily life, often on the seals to check and repair is needed. Mechanical hydraulic cylinder structure is simple, with it to realize reciprocating motion, can be eliminated when the deceleration device, and no transmission gap, smooth movement, so in the hydraulic system of the machinery has been applied.
