1. Reasons for the leakage of hydraulic gear pump
1. The end face is leaking. This is the gap between the end face of the gear and the end thrust plate and is the cause of pump leakage. This place also occupies a large proportion of leakage. Therefore, wear of the thrust plate or floating bushing may cause leakage. increase pressure, which affects pump displacement and pressure;
2. Radial leakage. This kind of leakage refers to the leakage between the tooth top circle of the gear and the surface of the pump body cavity, and the wear of the tooth top or the pump cavity is aggravated, resulting in leakage;
3. The meshing line leaks, and the full-width meshing of the gear cannot be realized. The resulting leakage is called mesh line leakage, and the tooth surface is severely worn, resulting in increased leakage;
Solution: replace or repair thrust plate, replace or repair gear, replace or repair gear.
2. Reasons for cracks in the hydraulic gear pump body
1. Caused by improper installation of the pump;
2. The pump is suffocated by high pressure;
3. There is a problem with the screw pre-tightening torque, which leads to excessive stress and damage;
Solution: replace the new pump, install it according to the instructions, adjust the pump pressure, and adjust the screw preload torque.
The above content is the reason for the internal leakage of the hydraulic gear pump shared by Xiaobian and the cracks in the pump body. If the pump we use has these two situations, then we may try the reasons compiled by Xiaobian to solve the problem. Failed, hope to help everyone.
