三峡库区的高扬程长距离取水工程数量较多,以重庆市彭水县城取水泵站为例,在对取水点处水文、地质、地形等资料进行分析调研的基础上,经过技术经济方案比较,选择了安全可靠、运行管理方便的固定干井取水泵站方案。系统介绍了水源、取水口、取水泵站及水锤防护的设计参数及考虑因素。实际运行结果表明:固定干井取水泵站运行可靠,作业环境好;水锤防护措施可有效保障泵站及输水管安全。
In the Three Gorges Reservoir Area, there are many high-lift and long-distance water intake projects. Taking Pengshui County Water Pumping Station in Chongqing as an example, based on the analysis of hydrology, geology and topography at the water intake points, , Choose a safe and reliable, easy operation and management of fixed dry pumping station scheme. The system introduced the water source, water intake, water pumping station and water hammer protection design parameters and considerations. The actual operation results show that the fixed dry-well water pumping station is reliable and the operating environment is good. The water hammer protection measures can effectively ensure the safety of pumping station and water pipe.
