淮安县地处淮河下游,由于低洼圩区较多,涝渍灾害成为全县农田水利建设的主要矛盾。因此,大力发展了机电排灌,兴建了占全县排灌设备保有量67.8％的低扬程泵站。然而,据测试资料分析,这类泵站的装置效率仅有27.4％。中小型泵站,尤其是扬程在2.5米以下的低洼圩区泵站能耗大也是一个普遍的、突出的问题。近几年来,我们紧紧围绕提高泵站经济效益这个核心,多方 Huai’an County is located in the lower reaches of the Huaihe River, due to more low-lying polder areas, waterlogging disaster has become the county farmland water conservancy construction of the main contradictions. Therefore, vigorously develop the mechanical and electrical drainage, construction of the county accounted for 67.8% of irrigation and drainage equipment, low-lift pump station. However, according to test data analysis, such pumping station device efficiency is only 27.4%. Small and medium-sized pump stations, especially the head of low-lying polder area 2.5 meters below the pumping station energy consumption is also a common, prominent problem. In recent years, we focus on improving the economic efficiency of pumping station this core, multi-party
