1. 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. 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.
2. Transformation of pump impeller
When using the pump flow the flow ratio of the actual needs of the large, and is not the speed control and speed regulation device price uneconomical, the original pump impeller turning a or replacement of the impeller, reducing the flow and reduce the lift, to reduce pump power consumption.
3. Water pump series, parallel operation:
When the water pump is connected in series or in parallel, the characteristic curve of the water pump will be changed, so as to meet the actual needs of the load, to achieve the best matching, so as to save the electric energy. Pumps can be one or two of the efficient energy-saving VVVF automatic regulating water, the rest of the pump full load operation, which can make the whole pump unit is always efficient and energy saving operation state, and the flower and less investment.
4. 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. 1 can be removed in the middle of the middle of any 1, pumping 2 when the demolition of the middle of the 2, 4 or 3, 5, the first two are not pumping.
