基于长距离引水的多系统输水泵站的安全运行要求,以三维CFD仿真模拟和物理模型试验交互进行多方案比较和设计优化。经采用导流墩、底坎、进水孔等整流措施进一步改善水力条件和配水均匀性,实现进水流道的水流条件平顺、流态稳定,泵站万吨水占地仅为常规设计的50%,进、配水建筑物的沿程最大水位落差较经验参数设计法减少58%,达到了系统稳定可靠和节能减排的双重目标。
Based on the safe operation requirements of multi-system water pumping station with long-distance water diversion, the three-dimensional CFD simulation and physical model test are used to carry out multi-scheme comparison and design optimization. After adopting diversion measures such as diversion pier, bottom ridge and water inlet hole to further improve the hydraulic conditions and water distribution uniformity, the water flow condition of the inlet runner is smooth and the flow state is stable. The water pump station occupies only the conventional design of 50 Compared with the empirical parameter design method, the maximum water level drop along the road of%, inlet and distribution buildings is reduced by 58%, which achieves the dual goal of stable and reliable system and energy saving and emission reduction.
