江苏省武进县地处太湖流域,是我国发展机电灌排历史较早的一个县,境内地势平坦,河网交错,总耕地面积145万亩,其中97%靠提水灌溉,区后排涝、除渍也全靠机电。为了提高泵站的装置效率,从1981年6月到1982年9月在全县范围内对部分泵站进行了测试,对全县泵站装置效率做了估算,分析了效率低的原因。从动力、水泵、传动、管理、进出水池五个方面做了一些改造,取得了较好效果。并从每提高1%装置效率所化费的单位投资及泵改投资的回收年限两方面初步分析了泵站改造的经济效益。
Located in the Taihu Lake Basin, Wujin County, Jiangsu Province, is one of the earliest counties in developing electromechanical irrigation and drainage in China with flat terrain and interlaced river networks. The total cultivated area is 1.45 million mu, of which 97% Stains also rely entirely on mechanical and electrical. In order to improve the efficiency of pumping stations, some pumping stations were tested within the county from June 1981 to September 1982, the efficiency of pump stations in the whole county was estimated, and the reason of low efficiency was analyzed. From the power, water pumps, transmission, management, access to the pool of five made some transformation, and achieved good results. And analyzed the economic benefits of pumping station transformation from two aspects: the unit investment that is increased by 1% and the recovery period of pump investment.
