Abstract:
The design and average heads of Jingtou pumping station in Suqian city are both 1.7 m, and thus shaft tubular pump system is applied to adapt its characteristics of low heads. The optimum hydraulic design for the inlet and outlet conduits of the pump system were conducted using the numerical simulation method of three-dimensional turbulence flow, and the hydraulic performance of the pump system was verified using model test. The results indicated that the flow pattern in the inlet and outlet conduits is uniform and smooth, the velocity distribution uniformity and the average angle into the pump reach 98.7% and 88.7° at the impeller chamber inlet section, respectively, and the hydraulic losses of the optimized conduits are low. Moreover, the efficiency and critical net positive suction head of the pump system were 80.3% and 3.11 m under the design head conditions, respectively, which were similar to those obtained from model test (the efficiency and critical net positive suction head were 81.1% and 3.3m under the design head conditions). Therefore, the selection and design for the shaft tubular pump system in Jingtou pumping station are reasonable and optimal, which lays a foundation for the safe, stable, and efficient operation of the pumping station.
