摘　　要：本文以盐环定扬黄工程提水系统设计为模型,研究分析了大型多泥沙梯级提水灌溉泵站水泵选型设计,结合水流水质情况,从水泵型式、气蚀、过流部件材质、机组安装高程确定等几方面进行研究。该研究为大型梯级提水工程的水泵机组选型设计提供了经验与参考。Based on the design of the water lifting system of the Yellow River Project in Yanhuanding, this paper stud- ied and analyzed the design of pump type selection for large-scale sediment ladder pumping irrigation station. Com- bining with the water quality, the pump type, cavitation, the material of flow passage parts and the determination of unit installation height were studied. This study provides experience and reference for the selection and design of pumping units for large cascade water pumping projects.
