The Regression Model Used in Optimizing Operation of Pump Sets

3 regression models of operating functions for pump sets are established according to measured working point of pump.The factors of the model are determined with the least square regression method and an analysis on the effectiveness of the factors is also made.The application of pump efficiency model shows that the operating parameters of pump obtained from the models are basically consistent with the measured values when fluid falls into the hydraulic smooth rcgion and transition region of turbulent flow.
