一、工程概况芮城县大禹渡电灌站是一座大型引黄电灌站,渠首枢纽工程共分二级,总扬程214米,灌溉面积28万亩。一级站扬程20.8米,安装20SK—19型水泵14台,抽水量每台0.56米~3/秒,共计7.4米~3/秒。二级站扬程193.2米,安装24台10DK—9×2A型水泵,上水量为5.7米~3/秒。一级站直接从黄河抽水,水泵受黄河泥沙的磨损是难以避免的,只能采取抗泥沙磨损的
First, the project overview Dayu Du Ruicheng County Electric Power Irrigation Station is a large irrigation station, the first drainage project is divided into two levels, with a total lift of 214 meters, 280000 acres of irrigated area. A station head 20.8 meters, the installation of 20SK-19-type pump 14, pumping 0.56 m ~ 3 / s each, a total of 7.4 m ~ 3 / s. The secondary station has a lift of 193.2 meters and 24 sets of 10DK-9 × 2A pumps installed on the water of 5.7 m 3 / s. A station directly from the Yellow River pumping, the Yellow River sand pump wear is hard to avoid, can only take anti-sediment wear
