Abstract In order to solve the domestic structure selection problem of low-lift pump,based on the large-scale bulb tubular set of Linjiaba pumping station in South-to-North Water Diversion Eastern Route Project,a Computational Fluid Dynamic(CFD) study on structure,flow channel hydraulic loss,pressure distribution and flow rate distribution of the large-scale bulb tubular pump suitable for low-lift operating mode is conducted.The simulated results are compared with the model experiment.Results indicate that CFD results approach the experiment data.The study provides references for structure choice and design of domestic low-lift pump station.large-scale pumping station;low-lift;bulb tubular pump;computational fluid dynamic
