Water taking system and method for high-altitude, large-longitudinal-slope and high-sand-content mountainous river
The invention discloses a water taking system and method for a high-altitude, large-longitudinal-slope and high-sand-content mountainous river. The system comprises a self-control self-priming pump, a desanding pretreatment system, a water collecting tank and a long-axis deep-well pump, a water suction pipe of the self-control self-priming pump extends into a river, a grid net is arranged on a water inlet of the water suction pipe, and the grid net is covered with a grid net; the self-control self-priming pump is communicated with the desanding pretreatment system through a water conveying pipeline so as to input river water into the desanding pretreatment system, the desanding pretreatment system is communicated with the water collecting tank, and the long-axis deep-well pump is arranged at the top of the water collecting tank and extends into the water collecting tank. The system can meet the water taking requirements under the conditions of high altitude, large sand content, large riverway longitudinal slope, large water flow speed and large fall of the water conveying pipeline, the sand content and water pump lift entering a factory area are greatly reduced, abrasion of a water pump impeller is reduced, water taking is stable, and the service life of equipment is prolonged.
本发明公开了一种高海拔、大纵坡、高含沙山区河流取水系统和方法。该系统包括自控自吸泵、除砂预处理系统、集水池和长轴深井泵，自控自吸泵的吸水管延伸至河流中，吸水管的进水口上设置有格栅网，格栅网外部罩设有格网；自控自吸泵通过输水管线与除砂预处理系统相连通以向除砂预处理系统内输入河流水，除砂预处理系统与集水池相连通，长轴深井泵设置在集水池的顶部并延伸至集水池内。该系统能够满足高海拔、含砂量较大、河道纵坡大、水流速度大且输水管线落差大的情况下的取水需求，大大降低含砂量及水泵扬程进入厂区、降低水泵叶轮磨损、取水稳定并延长了设备的使用寿命。
