Power unit manufacturers analyze common problems

The power unit is also a commonly used hydraulic power system. It will also encounter some situations during use. The power unit manufacturer has summarized two frequently seen situations. One is the occurrence of high temperature and heat, and the other is The tubing is too thin, and the power unit manufacturers share the two situations below.

There are three reasons for a high temperature.

1. It may be because the system has been overloaded, that is, it has exceeded its large capacity, which is mainly manifested as excessive pressure or excessive speed.

2. The reason may be that there is a problem with the hydraulic oil used in the hydraulic power unit. For example, it is likely that the cleanliness of the hydraulic oil is not up to standard, causing serious internal wear and tear, reducing the volumetric efficiency and causing leakage;

3. The reason is that the used oil outlet pipe is too thin and the oil flow rate is too high.

The second situation is that the flow rate of the hydraulic power unit does not meet the standard, causing the system to run poorly and affecting the work effect. The reason for this problem is mainly caused by four factors:

1. Insufficient cleanliness of the oil inlet filter element affects oil absorption;

2. The installation position of the pump is too high;

3. The oil suction pipe of the gear pump is too thin, which affects the oil absorption;

4. Air leakage at the oil suction port joint, resulting in insufficient oil suction.

The above are common problems analyzed by power unit manufacturers. It should be noted that during the operation of the system, the temperature of the hydraulic oil may rise to a certain extent. When the temperature rises, the viscosity may decrease. In order to ensure the normal operation of the hydraulic pump station, we need to control the oil temperature below 60°C. In addition, when choosing hydraulic oil, we also need to consider choosing those hydraulic oil products that can still maintain stable performance at different temperatures.
