| 摘 要： | 蔺家坝泵站作为我国首座采用齿轮箱传动的大型灯泡贯流泵机组的泵站,为使水泵装置具有较优的水力性能,采用CFD仿真技术对该灯泡贯流泵机组的流道进行了优化设计和计算,并与水泵装置模型试验结果进行了比较;重点分析了灯泡体的支撑结构、叶片调角机构、主轴密封装置、轴承布置、齿轮箱及同步电动机等主要设备的结构设计.结果表明：CFD仿真技术应用于灯泡贯流泵机组的水力性能优化是可行的,蔺家坝泵站采用大型灯泡贯流泵机组,在设计净扬程2.4 m工况下,水泵装置效率达到78%,且气蚀性能良好,技术参数均达到了南水北调东线工程的要求;大型齿联传动灯泡贯流泵机组的成功运行,为国内其他大流量低扬程泵站的机组选型、设计及制造提供了可借鉴的经验.
