Simple troubleshooting method of hydraulic power unit

Both of these problems are more common when using hydraulic power packs.

1. The temperature is high, and there is a serious heating problem.

First, it may be because the system is overloaded, that is to say, it exceeds the maximum bearing capacity of the product itself, which is mainly manifested as too high pressure or too fast rotation speed；

Second, there may be problems with the hydraulic oil used by the hydraulic power unit. For example, it is likely that the cleanliness of the hydraulic oil is not up to standard, resulting in serious internal wear problems, resulting in reduced efficiency and leakage problems.

Third, because the oil outlet pipe used is too thin and the oil flow rate is too high, the temperature is abnormal.

 

2. The flow rate of the hydraulic power unit is not up to standard, which leads to the poor operation of the system and affects the operation effect.

First, the cleanliness of the oil inlet filter element is insufficient, which affects the oil absorption;

Second, the installation position of the pump is too high;

Third, the oil suction pipe of the gear pump is too thin, which affects the oil absorption;

Fourth, the oil suction port joint leaks, resulting in insufficient oil suction.
