The hydraulic cylinder is the actuating element that converts hydraulic energy into mechanical energy in the hydraulic system. The faults can be basically summarized as hydraulic cylinder misoperation Jinhua Oil cylinder manufactor It is unable to push the load and the piston slips or crawls. It is not uncommon for hydraulic cylinder failure to cause equipment shutdown. Therefore, Jinhua Oil cylinder Attention should be paid to the fault diagnosis, use and maintenance of hydraulic cylinder. The main reason for excessive wear of piston seals is that the speed control valve is improperly adjusted, resulting in excessive back pressure, improper installation of seals or contamination of hydraulic oil. Secondly, foreign matters enter during assembly and the quality of sealing materials is poor.

Because the hydraulic cylinder has to bear a great pressure, the heavier the load, the greater its pressure will be. Therefore, the maintenance of the hydraulic cylinder is an important part of the maintenance of the entire hydraulic system. The hydraulic cylinder is the heart of the hydraulic system, Jinhua Oil cylinder It is difficult to repair the heart problem, so the maintenance of the hydraulic cylinder should be careful. First, rust prevention. Because the piston part of the hydraulic cylinder will extend the cylinder in the working state, Jinhua Oil cylinder manufactor Naturally, it will be corroded by oxide and acid gas, which requires us to coat it with proper grease for protection.

The valve core of the flow valve in the hydraulic cylinder is blocked, which is easy to cause the action failure of the hydraulic cylinder. We need to check whether there are pollutants in the oil in the hydraulic cylinder and whether the valve body is worn. It is necessary to check whether the piston rod seal is too tight, Jinhua Oil cylinder Whether there are pollutants entering, whether the axis line is aligned, and whether the easily damaged components fail. If the pressure controlled by the hydraulic system is too low, the action of the hydraulic cylinder will also fail, Jinhua Oil cylinder manufactor At this time, it is necessary to check the control pressure source to ensure that the pressure value is consistent with the specified value of the system.

Compared with mechanical transmission, hydraulic cylinder transmission is a new transmission form. Hydraulic transmission has a history of more than 200 years since the birth of hydraulic press, but hydraulic transmission has been going on for many years. Especially after the 1960s, with the development of atomic energy science, space and hydraulic technology, Jinhua Oil cylinder It permeates all fields of the national economy, including agricultural machinery, automobiles, light textile, shipbuilding, petroleum, aviation and machine tool industries, Jinhua Oil cylinder manufactor Hydraulic technology lists some application examples of hydraulic and pneumatic transmission.
