1.The use of high efficiency and energy saving pumps and efficient low loss motor, and to improve the efficiency of the transmission device.
2.The correct choice of pump motor power. Large horse drawn trolley". Water pump motor with large change of capacity.
When the motor power is much larger than the actual need, the method can be used to replace the motor power saving.
3.Choose reasonable head:
When the pump head is too much to stay too much time will be wasted, so we should reasonably determine the pump operating point of the head.
4. Reduce pipe resistance:
Remove excess pipe fittings and unnecessary and sharp turn, to reduce the pipeline resistance, reduce the power consumption of water conveying unit. The method of reducing the resistance of the pipeline is:
1).Pipe design should be reasonable.
2).Increasing the diameter of the tube or double tube drainage to reduce flow.
3).As far as possible to shorten the length of pipe, and the valve to reduce the elbow joint, and especially to avoid sharp appearance.
4).To improve the inner wall of the pipe finish or coating.
5).Timely removal of dirt on the inner wall of the pipeline.
5.Water pump speed regulation power saving:
The power consumption of the pump is proportional to the three power of the speed of the unit, so the speed of the unit can be changed according to the actual demand of the load. The pump speed control measures, the initial investment is larger, but the power saving effect is obvious, especially suitable for large capacity water pump. Should pay attention to the head, the greater the resistance curve, the more flat, even if there is a slight change in speed, the flow will be greatly changed, and the power saving effect is poor.
6.Transformation of pump impeller:
When the pump in use than the actual needs of the traffic, but not with speed control or speed control device of high uneconomical, the original pump impeller turning one or replacement of the impeller, to reduce the flow and reduce the lift, in order to reduce the power consumption of water pump.
7.Multi-stage pump using pumping operation:
If the multi-stage pump has excess pressure, can be pumped to 2 ~ 1, to improve efficiency, reduce the loss of purpose. Pump 1 can be removed at any level of 1, pumping 2 when the demolition of the middle of the 2, 4 or 3, 5 level can be.
