摘  要:为加快推进宁夏中部干旱带脱贫攻坚、解决水资源短缺问题,宁夏回族自治区水利厅提出了固海扬水工程渠首泉眼山泵站“6+1”运行调整工程,将首级泵站由原设计5台运行、2台备用“5+2”运行方式调整为6台运行1台备用“6+1”运行方式,增加流量3.8 m3/s,配套对后续泵站及渠道进行增流改造。固海“6+1”运行调整工程开展了水泵增流叶轮研制和试验运行、泵站运行及优化调度、渡槽降低糙率等研究。研究成果为本工程改造提供了技术支撑和低成本解决方案,在固海扬水工程增流改造工程实践中得到了应用,取得了明显成效。In order to reduce poverty and alleviate water shortage in central arid zone,the water resources department of Ningxia Hui Autonomous Region proposed to change the operation mode of Quanyanshan Pumping Station at the head of Guhai Water Lifting Scheme,from the original design of 5 sets of operation and 2 sets of standby to 6 sets of operation and 1 set of standby.This can help to increase the flow by 3.8 m3/s by subsequent rehabilitation of pumping stations and canals.Research and test operation had been applied booster impeller of pump,optimal operation of pump station,and reduction of the roughness of the aqueduct.The results provide technical and low-cost solutions for upgrading of the pumping stations,and obtained obvious achievements with its application in practice.
