Characteristics of common faults in hydraulic systems

The failure rate during the equipment debugging phase is relatively high, and there are many complex problems, characterized by the interweaving of planning, manufacturing, installation, and handling issues. In addition to mechanical and electrical issues, common hydraulic system faults include:

1) Leakage at the joint connection.

2) The movement speed is unstable.

3) The valve core is stuck or the movement is not sensitive, resulting in the malfunction of the actuator.

4) The damping small hole is blocked, resulting in unstable system pressure or inability to adjust the pressure.

5) Valve components are missing tension springs or seals, or pipes are connected incorrectly, causing confusion in operation.

6) Improper planning and selection can cause the system to overheat, or the actions to be uncoordinated, resulting in inadequate azimuth accuracy.

7) Poor machining quality of hydraulic components or poor device quality, resulting in insensitive valve actions.

8) Long term operation, aging of seals, and wear of vulnerable components result in increased leakage in the system, leading to a significant decrease in system power
