To enhance operational efficiency and safety of low-lift, high-flow vertical shaft tubular pumping station, taking a large-scale pumping station in Tianjin for an example, the optimization design of inlet and outlet flow passages was conducted by the CFD numerical simulations. The practical aspects including flow passage head loss, velocity uniformity, motor chamber space, and hoisting equipment capacity were studied. By considering the characteristic flow rates and lift of the pumping station, optimal combinations of hydraulic models and flow passages were selected. The overall energy performance of the pumping station system was simulated to evaluate its applicability and efficiency. The design scheme was further validated through physical model tests. The results demonstrate that inlet flow passage schemes J1 and J2 exhibited favorable velocity uniformity and head loss characteristics, with scheme J1 showing marginally superior performance. For outlet flow passages, schemes C1 and C2 displayed comparable performance, though C2 offered a more rational equipment layout due to its shorter transition section. The combined scheme J2+C2 proved suitable for low-lift, high-flow pumping stations when considering motor chamber dimensions and gate design. Ultimately, the TJ04-ZL-06 hydraulic model(impeller diameter of 4 m, rotational speed of 88.9 r/min, blade installation angle of-6°) was recommended, ensuring safe and efficient operation across the specified lift and flow rate ranges.
