摘要
综述近年来低扬程泵装置流动特性及水力性能方面的研究进展,分别从进出水流道、叶轮和整体泵装置等方面对目前研究成果进行分析,指出为了更真实地描述泵装置流动与性能研究,应树立从装置的角度去认识泵装置及其各过流部件的内、外特性的思想。目前需要在泵装置内部三维流动测量和低扬程泵装置选型方法两方面作重点研究。
A review is made on recent research on flow characteristics and hydraulic performances of low lift head pumping station. The advances in research on flow in inlet and outlet passages, internal impeller and the whole pump set are described in detail. In order to describe the flow in pump set more accurately, the conception of integral hydraulic performances of pump set should be established to discover the internal and external character of different flowing components in hydraulic turbine. Finally, the direction for further study is pointed out, i.e. the 3-D flow field measurement and the optimal type selection for low llft head pumping station.
