广西靖西县那多水电站原设计为“三井五泵”机电抽排水,运行后发现,所有水泵都正常工作时,可以满足防洪要求,而其中某一套抽水设备发生故障时,电站防洪工作便吃紧。为此,技术人员将排水系统改为集水自流自排式,实现了水电站集水自排系统可靠运行又节约站内用电,还减轻了值班员劳动强度。 The Jingxi Naduo Hydropower Station in Guangxi Province was originally designed as “Mitsui Five Pumps” for mechanical and electrical pumping and drainage. After running, it was found that all the pumps are working properly to meet flood control requirements. When one of the pumping units fails, Work will be tight. To this end, the technicians will change the drainage system to catch-flow gravity self-draining to realize the reliable operation of the water-collecting and self-draining system of the hydropower station and save the electricity consumption within the station, and also reduce the labor intensity of the attendant.
