| Abstract: | The computation of hydraulic loss is the basis of performance predication for low-lift pumping station.The function of loss computation was put forward.Loss revise of inlet passage on the non-BEP(Best Efficiency Point)and whirl loss of outlet passage was brought up.The method is used to explain the different performance between pump bowl and pumping system.A design program based on flow analysis and performance predication was developed for the design and construction of pumping stations. |
