摘　　要：固海扬水工程是宁夏建设最早、规模最大的公益性生态扶贫扬黄灌溉工程,也是宁夏中南部重要的水资源保障的大型扬水工程,为宁夏中部干旱带脱贫攻坚和经济社会发展提供着坚实的水资源保障。固海扬水工程梯级泵站增流改造技术的研究与应用,以固海扬水工程系统泉眼山泵站至黑水沟泵站1—5梯级泵站增流改造为对象,通过固海3—5梯级泵站增流叶轮研制及运行试验、泵站增流综合技术研究及应用、固海1—5梯级泵站输水系统干渠及其建筑物病害治理及增流等关键技术研究及应用,实现固海1—5梯级泵站工程挖潜改造,为大型梯级泵站工程增流改造技术研究和生产应用提供典型借鉴。The Guhai Pumping Irrigation Project is the earliest and largest public welfare ecological poverty alleviation and Yellow River Irrigation Project built in Ningxia.It is also an important large-scale water raising project for water resources protection in central and southern Ningxia.It provides a solid foundation for poverty alleviation and economic and social development in the arid zone of central Ningxia.Water resources protection.For the research and application of flow-increasing transformation technology for cascade pumping stations in Guhai Pumping Project,this paper takes the flow-increasing transformation of cascade pumping stations 1—5 from Quanyanshan Pumping Station to Heishuigou Pumping Station in Guhai Pumping Project System as the object;through the development and operation test of flow increasing impellers in Guhai 3—5 cascade pumping stations,research and application of comprehensive flow increasing technology for pumping stations,research and application of key technologies such as disease management and flow increasing of main canals and buildings in the water conveyance system of Guhai 1—5 cascade pumping stations,it has realized the potential tapping and transformation of the Guhai 1—5 cascade pumping station project,providing a typical reference for the research and production application of flow increasing transformation technology for large-scale cascade pumping station projects.
