【摘要】：引汉济渭工程黄金峡水利枢纽是陕西省境内一项重要的大型跨流域调水工程,泵站装机容量和设计流量均为目前国内甚至亚洲在建和已建泵站之最,且调水过程复杂、调水流量分布范围宽广。在分析黄金峡泵站调度原则及运行方式的基础上,综合比较目前国内外大型泵站机组设计制造水平、枢纽建筑物及机电设备投资等因素,详细论证了大型单级单吸离心式水泵机组台数和性能参数的确定方法及其影响因素,并给出了黄金峡泵站机组选型设计的最优方案,同时论证了采用变频调节的必要性及其效果。研究结果可为大型调水泵站机组的选型设计提供参考。
[Abstract]:Jinxia Water Conservancy Project is an important inter-basin water diversion project in Shaanxi Province. The installed capacity and design flow of pump station are the most in construction and construction in China and even in Asia, and the process of water transfer is complicated. On the basis of analyzing the dispatching principle and operation mode of Jinxia pump station, the design and manufacture level of large pumping station units at home and abroad, the investment of hub buildings and mechanical and electrical equipment, etc., are compared synthetically. The method of determining the number and performance parameters of a large single-stage single-suction centrifugal pump unit and its influencing factors are discussed in detail, and the optimal scheme for the selection and design of the unit type of the Jinxia pumping station is given. At the same time, the necessity and effect of adopting frequency conversion regulation are demonstrated, and the results can be used as a reference for the selection and design of large water transfer pumping station units.
