1. Impact on pump head
Water pump commonly used motor for 2 pole, 4 pole, 6 pole, deceleration motor and speed control motor. The same type of pump maintenance under constant flow and motor speed lower pump head lower, outlet pressure smaller, so high lift pump generally choose two pole motor, low lift pump selection 4 and 6 pole motor, motor speed in the pipeline centrifugal pump have typical applications.
2. Impact on pump flow
Pump flow in the export to maintain a constant pressure, the higher the speed of the pump flow is greater. The same types of single-stage single suction centrifugal pump in order to reduce the flow process on will be cutting impeller diameter using and not using a small motor should be for low speed motor in the flow and pressure also decreased, it is difficult to meet the same process requirements.
3. Effect on pump efficiency
The efficiency of the pump marks the level of the pump efficiency, reflecting the use of the pump motor. Centrifugal pump motor speed on the efficiency of the impact of a disproportionate relationship, but the pump body's finish, the tightness of the seal, the layout of the pipeline and other factors affect the efficiency of the use of the pump.
