中国农机院等9个单位对全国一百余座大型轴流泵站进行了调查,其中资料齐全的48座泵站装置效率的分析结果,低于《国营机电排灌站实行按八项技术经济指标考核的暂行规定》(以下简称“规定”)电力站综合装置效率54.4%的在29.2%以上,最低的低达26.5%。对于一些多年平均装置效率较低的泵站,首先,应研究选择经济运行方案运行、提高装置效率,降低能源单耗和排灌成本、尽可能使其达到或接近“规定”的要 China Agricultural Machinery and other nine units of the country’s more than 100 large-scale axial flow pumping station were investigated, of which 48 complete data sets of pumping station efficiency analysis results, lower than the “State-run mechanical and electrical pumping station implementation of the eight technical and economic indicators Interim Provisions on Assessment ”(hereinafter referred to as“ Regulations ”) 54.4% of the efficiency of integrated power station installations in the 29.2%, the lowest as low as 26.5%. For some pumping stations with low average annual plant efficiency, first of all, the operation of selecting economic operation plans should be studied to improve plant efficiency, reduce energy consumption per unit and irrigation and drainage costs, and try to bring them to or near the “regulation” as much as possible
