Six common faults of hydraulic transmission system

Hydraulic transmission system is widely used in construction machinery, and it is also an important executive mechanism of construction machinery. It plays an important role. The failure of hydraulic system will affect the operation efficiency of construction machinery and reduce the safety of construction machinery. In the actual operation of hydraulic transmission system of construction machinery, there are six common faults.

First, the power mechanism of the hydraulic transmission system does not move or is unstable, which greatly affects the operation or normal operation of the machinery.

Secondly, the power of the hydraulic transmission system is insufficient or weak, and the actuator cannot bear the external load and does not move due to this fault.

Thirdly, the temperature of the hydraulic transmission system is too high. The high temperature of the system will cause the oil to deteriorate or become thinner, thus reducing the operating efficiency of the system, and at the same time, it will also cause the deformation or damage of the components.

Fourth, hydraulic transmission system leakage fault, which will cause loss and waste of resources, and also affect the normal operation of machinery. The higher the system temperature, the faster the oil leakage.

Fifthly, the hydraulic transmission system is blocked. The hydraulic system is blocked, which may damage the components or cause the components to not move to the set position, resulting in system failure.

Sixth, the noise of hydraulic transmission system. Excessive noise of hydraulic system will cause system vibration and reduce the stability of system operation.

The above are six common faults of hydraulic transmission system. The hydraulic system should be maintained in time after being used for a period of time to find and solve problems as soon as possible.
