The oil cylinder manufacturer explained that the fatigue of hydraulic equipment will always exist in the daily operation process, so it is necessary to stop regularly for inspection and maintenance during the operation process. Hydraulic cylinder seals often need to be maintained, overhauled and maintained to increase the service life of cylinder seals and the performance of seals.

The piston of the hydraulic support cylinder is the main component to avoid the internal leakage of hydraulic oil. During the inspection process, the machine can be operated according to the normal operating specifications, and then operate the reversing valve to extend the piston to its position. At this time, the hydraulic support cylinder is in the rising state. Disassemble the oil port of the hydraulic cylinder's oil return pipeline and observe whether there is leakage of hydraulic oil. If hydraulic oil leakage is found, it is necessary to check the wear of seals and whether the sealing ring between piston and piston rod is intact.

Secondly, if the inspection results show that the seal and the guide support ring are damaged to varying degrees, the material of the same specification should be selected according to the structural form of the original seal or guide support ring, so as to reduce the oil film thickness of the seal and the sealing surface, so as to avoid the recurrence of the hydraulic support cylinder leakage fault.

In the hydraulic cylinder, poor sealing of the seals can cause oil leakage, which makes the mechanism unstable, reduces the volumetric efficiency, pollutes the environment, and in serious cases, it will not build up pressure and the system will not work. Therefore, in daily life, it is necessary to often check and repair the seals of hydraulic cylinders.

The mechanical hydraulic cylinder has a simple structure. When it is used to realize reciprocating motion, it can avoid the reduction device, and there is no transmission clearance, so it is used in the hydraulic system of various machines. Because of this, oil cylinder manufacturers should choose some hydraulic cylinders that can resist rust for use.

If the rated hydraulic cylinder is used in rain and rain or fresh water, the amount of particulate dirt mixed can be judged mainly by the size of the impact. Therefore, the hydraulic cylinder at this time is relatively prone to oxidation and rust. In addition, the hydraulic components are also relatively easy to enter dirt during processing and assembly. In addition, the hydraulic cylinder is used in different environments, And the air leakage or the insoluble object formed after the water leakage.
