A dynamic time-history analysis of pump-house of Huaiyinsanzhan Pumping Station caused by the flow is made to calculate the dynamic response of bulb tubular pump-house.

Numerical study of 3D flow in a bulb tubular pump system;

The method was applied to measure the hydraulic losses of inlet and outlet conduit of bulb tubular pump system of the pumping station re.

According to the selection of pump models in the Huai-an fourth pumping station and the Huai-yin third pumping station of the eastern route of South-to-North Water Diversion, vertical axial flow pumps and bulb tubular pumps are compared and studied in the low-lift-head pumping station,and their selecting ranges are put forward on the basis of current conditions.

CFD calculation for large-scale bulb tubular pump;

With the characteristics of smooth flow patterns in the inlet and outlet conduits, less hydraulic loss and high system efficiency, a bulb tubular pump system is especially suitable for pumping stations of the East-Route South-to-North Water Transfer Project.
