The main reasons for the high pressure of gear pumps and gear oil pumps are as follows: The outlet pipeline of the gear pump is smaller than the theoretical pipeline diameter required by the pump, which causes the pump outlet resistance; the gear pump and gear oil pump have not cleaned the pipeline for a long time, and the pipeline is stuck The main reasons for the excessive pressure of gear pumps and gear oil pumps are as follows:
First, the outlet pipeline of the gear pump has a smaller diameter than the theoretical pipeline actually required by the pump, resulting in a large outlet resistance;
Second, the gear pump and gear oil pump have not cleaned the pipeline for a long time, and there are too many stagnant materials in the pipeline, and the pipeline is not smooth, which causes too much circulation resistance of the gear pump;
Third, the viscosity of the medium conveyed by the gear pump is too large, and the pipeline is too thin, resulting in excessive pump resistance;
Fourth, the inlet pipeline of the gear pump leaks air, causing cavitation during the operation of the gear pump, resulting in increased pump pressure and loud pump noise;
Fifth, the valve on the pipeline of the gear pump is not opened during the conveying process, resulting in excessive resistance of the gear pump.
Sixth, the gear pump pipeline is too long and the pump head cannot be satisfied, resulting in excessive pump resistance and increased pressure.
