During daily operation, Hydraulic equipment There will always be fatigue during operation, so it is necessary to stop regularly for inspection and maintenance during operation. Hydraulic cylinder Seals often need professional maintenance, overhaul and repair to improve the service life of cylinder seals and the performance of seals.

The piston of the hydraulic support cylinder is the main element to prevent the internal leakage of hydraulic oil. During the inspection, the machine can be operated according to the normal operating specifications, and then the reversing valve can be operated to extend the piston to the limit position. At this time, the hydraulic support cylinder is in the lifting state, and it can be disassembled Hydraulic cylinder Check the oil port of the oil return pipeline to see if there is any leakage of the hydraulic oil. If hydraulic oil leakage is found, it is necessary to check the wear of the seals and whether the seal ring between the piston and the piston rod is intact.

Secondly, if the inspection results show that the seals and guide support rings are damaged to different degrees, they should be made and replaced with materials of the same specification according to the structural form of the original seals or guide support rings, so as to effectively reduce the oil film thickness of seals and sealing surfaces and avoid the recurrence of hydraulic support cylinder leakage.

In the hydraulic cylinder, poor sealing of the sealing elements can cause oil leakage, which makes the movement of the mechanism unstable, reduces the volumetric efficiency, and pollutes the environment. In serious cases, the pressure will not be established, and the system will not work. Therefore, it is very necessary to check and maintain the seals of hydraulic cylinders frequently in daily life.

The mechanical hydraulic cylinder is simple in structure and reliable in operation. When it is used to realize reciprocating movement, the reducer can be avoided, and there is no transmission clearance, and the movement is stable. Therefore, it is widely used in various mechanical hydraulic systems. Because of this, some hydraulic cylinders that can effectively prevent rust should be selected for use.

If the rated hydraulic cylinder is used in the wind, rain or fresh water, it is mainly based on the size of the impact to effectively judge the amount of mixed particles, so at this time, the hydraulic cylinder is prone to oxidation and rust, and the hydraulic components are also relatively easy to enter the dirt during processing and assembly, There are also air leaks or insoluble objects formed after water leaks due to the use of hydraulic cylinders in different environments.
