Common Problems and Solutions in Excavator Hydraulic Systems

in 

Various problems often occur during the use of the excavator hydraulic system, which can seriously affect the normal operation of the mechanical equipment. To solve these problems, Aprilparts engineers summarized some common problems and solutions.

Common Problems and Solutions in Excavator Hydraulic Systems

Question 1: Oil leakage in the hydraulic system.

Oil leakage in the hydraulic system is one of the common problems in the hydraulic system of excavators. Oil leakage will cause the hydraulic oil pressure to drop and affect the working effect of the hydraulic system.

The solution is to first check whether the seals of the hydraulic system, such as sealing rings, gaskets, etc., are damaged or aged. If any damaged or aged seals are found, they need to be replaced in time.

Secondly, check whether the connection part of the hydraulic pipeline is loose and whether there are leak points. It needs to be tightened or the sealing gasket needs to be replaced.

Question 2: The hydraulic system is noisy.

Noisy hydraulic systems are another common problem, which can affect the comfort and working performance of the excavator.

The solution is to first check whether the inlet and outlet of the hydraulic pump and the pump are correctly connected and the seal is good. If the connection is incorrect or the seal is not good, it will need to be reconnected or the seal replaced.

Secondly, check whether the hydraulic pump and valve are worn or damaged. If problems are found, they need to be repaired or replaced in time.

Question 3: The pressure of the hydraulic system is unstable.

Unstable pressure in the hydraulic system will cause the hydraulic system to not work properly. The solution is to first check whether the pressure regulating valve of the hydraulic system is adjusted correctly. If it is not adjusted correctly, it needs to be readjusted.

Secondly, check the opening status of the inlet and outlet valves of the hydraulic pump. If there is a blockage, it needs to be cleaned. At the same time, the hydraulic pump also needs to be checked for foreign matter. If so, it needs to be cleaned.

Question 4: The temperature of the hydraulic system is too high.

Excessive temperature in the hydraulic system will cause the viscosity of the hydraulic oil to decrease, increase energy consumption, and even cause damage to hydraulic components.

The solution is to first check whether the cooler of the hydraulic system is working properly. If the cooler needs to be replaced or repaired.

Secondly, check whether the filter of the hydraulic system is clean and whether it needs to be replaced. At the same time, the quality of the hydraulic oil also needs to be checked. If the oil quality is found to have deteriorated, the hydraulic oil needs to be replaced in time.
