摘要:
依托沙集泵站现有泵装置,通过CFD有限元软件建立三维数值模型,模拟不同工况下泵装置全流道流动。系统分析了不同水位组合、水泵叶片角度、叶轮中心高程以及顶面上翘角对泵装置性能的影响。研究表明,空化主要发生于叶片背面的进口区域和叶片外缘的周向区域,且下游水位13.5 m时仍存在较为明显的空化;叶片角度调整为-4?,可明显抑制空化,流量基本能满足要求,建议以-4?运行;叶轮中心高程小幅降低后,并未抑制空化范围,反而使装置效率有所下降;进水流道上翘角的影响较小,综合考虑施工成本与改造效果,不建议调整进水流道顶面。此研究可为类似工程提供一定的借鉴和指导。
Abstract:
Based on the existing pump device of the Shaji Pumping Station, a three dimensional numerical model was established using CFD software to simulate the full flow channel flow of the pump device under different operating conditions. A systematic analysis was conducted on the impacts of different water level combinations, pump blade angles, impeller center elevations, and top surface upturn angles on the performance of the pump device. The results show that cavitation mainly occurs in the inlet area on the suction side of the blades and the circumferential area at the outer edges of the blades, and obvious cavitation still exists when the downstream water level is 13.5 m. Adjusting the blade angle to -4° can significantly suppress cavitation while the flow rate basically meets the requirements, so it is recommended to operate the pump at a blade angle of -4°. A slight reduction in the impeller center elevation does not inhibit the scope of cavitation; on the contrary, it leads to a decrease in the device efficiency. The influence of the upturn angle of the inlet flow channel is relatively small. Considering the construction cost and renovation effect comprehensively, it is not recommended to adjust the top surface of the inlet flow channel. This study can provide certain reference and guidance for similar projects.
