黑龙江兰西县东升泵站座落于呼兰河左凹岸。原泵站分为基式钢筋混凝土及砖、石、木结构,建筑面积425m~2,底板为0.5m厚钢筋混凝土。设计11台24НДНС水泵,总流量12.21m~3/s,配套功率2530kW。实际安装3台24F(?)-230和4台20Sh-19水泵,总流量5.27m~3/s,配套功率1450kW。一、存在的主要问题1.渗漏严重。受枯水位及水泵吸程所限,水泵安装高程较低(124.80m)。由于河水变幅大(8.60m),投入运行以来,年年汛期底板渗水,墙缝漏水,廊道
Lanxi County, Heilongjiang Dongsheng Pump Station is located in Hulan left bank. The original pumping station is divided into basic type of reinforced concrete and brick, stone, wood structure, construction area of 425m ~ 2, the floor is 0.5m thick reinforced concrete. Design 11 units 24НДНС pumps, the total flow of 12.21m ~ 3 / s, supporting power 2530kW. The actual installation of three 24F (?) - 230 and four 20Sh-19 pumps, the total flow of 5.27m ~ 3 / s, supporting power 1450kW. First, there are major problems 1. Leak serious. By the dry water level and pump suction limit, the pump installation elevation is low (124.80m). Due to the large amplitude of river water (8.60m), put into operation, the annual flood season floor seepage, wall joints leaking water, gallery
