湖北省汉川泵站建于1970年,主要承担汉川县和天门县汈汊湖区的排渍任务,泵站的保护面积为1963平方公里,装机容量6×1600瓩,配6台28CJ—70大泵,采用虹吸式出水流道见图1,设计扬程5.6米,最高扬程9.0米。该站自建成以来,对该区的防涝排渍方面起了重大作用。但是随着生产建设的发展,抗灾标准的提高,在新的抗灾工程兴建以前,为了进一步地发挥已建泵站的效益,经常要求该泵站在外江水位超过出水流道驼峰底部高程一定程度下仍然运行或者尽
Hanchuan pumping station was built in 1970, mainly undertaking the discharging task in Hanchuan County and Qionglai Lake area of Tianmen County. The pumping station has a protected area of 1963 square kilometers and an installed capacity of 6 × 1600 瓩 with 6 sets of 28CJ-70 Large pump, siphon water outlet using Figure 1, the design lift of 5.6 meters, the highest head of 9.0 meters. Since its establishment, the station has played a significant role in waterlogging prevention and drainage of the area. However, with the development of production and construction and the improvement of disaster resistance standards, before the construction of the new disaster-relief project, in order to give full play to the efficiency of already constructed pumping stations, it is often required that the pumping station should, under the certain extent of the water level at the outer surface of the outlet hump, Still running or do it
