摘　　要：泵装置的各过流部件对装置性能有不同程度的影响,采用物理模型试验方法对贯流泵装置能量相关特性进行研究,分析出水流道型式、导叶体及转轮叶片数对泵装置能量性能的影响,并对贯流泵装置与立式轴流泵装置进行能耗计算,论证在特低扬程(2.0 m以下)工况时,贯流泵装置具有明显的高效节能优点。The flow components of the pump device have different degrees of influence on the performance of the device.The physical model test method was used to study the energy-related characteristics of the tubular pump device,and the influence of the water channel type,the guide vane body and the number of runner blades on the energy performance of the pump device was analyzed.The energy consumption calculation of the tubular pump device and the vertical axial flow pump device was carried out,which demonstrated that the tubular pump device had obvious advantages of high efficiency and energy saving under the working condition of ultra-low head(below 2.0m).
