[0042] Working principle:

[0043] The system can effectively reduce the leakage of hydraulic oil and improve the stability and safety of the system.

[0044] The system mainly includes a cylinder body 1, a piston 4, a movable rod 6, a sealing cover 2, an oil inlet and outlet 7, an oil pipe 8 and a control module 11, among which the cylinder body 1 is the main part of the whole system, and is used to contain hydraulic oil and components such as a piston 4. The piston 4 is connected to the cylinder body 1 through a movable connection, and a compensation structure 3 and two main sealing rings 5 ​​are provided on its outer surface. The compensation structure 3 is located between the two main sealing rings 5, and is composed of a compensation sealing ring 31 and a compensation ball 32.

In addition, the control module 11 also has monitoring, fault warning and data recording functions. It can monitor the operating state of the hydraulic cylinder system in real time. Once an abnormality is found, such as flow, temperature or pressure exceeding the preset range, the control module 11 will immediately send out a warning signal to remind the operator to take timely measures.
