【Abstract】 The authors analyzed a coerced circulating axial flow pump mainly used in chemical industry and found that there were many problems existed due to its structure without guide vane. To overcome these problems, an energy compensation method for parametric decision in model selection design was theoretically developed based on the analyses of pump models both with and without guide vane. Furthermore, the compensation curves related energy loss and water conservancy as well as pump specific speed are given to supply designer a reference.更多还原
