Disclosed is an optimized water pump energy conservation control method. The optimized water pump energy conservation control method comprises the following steps of 1) deriving a total input power calculation formula of a water pump, performing calculation according to the total input power calculation...
If working in metric units, you need to convert to the appropriate units (cubic meters per second for flow rate and meters for head) and adjust the constant in the formula accordingly. Is it possible for WHP to be zero?Yes, if there is no flow (Q=0) or no head (H=0), WHP ...
At present, some farmers in the Gaoyou Irrigation District have a good understanding of drainage water reuse and they usually pump drainage water temporarily when the opportunity arises. 3.3.1. Evaluation of Reusing Drainage Water The amount of water stored in the Zhongshi River is stabilized ...
