今年《排灌机械》第一期刊登了徐州市水利局王开林同志写的“机电排灌站合理配套与省水节能”一文中说,徐州市的机电排灌站的平均装置效率为39%,每千吨米的能源单耗为7度(大于部标准5度)。在6683台中,配套不合理的占30%;经过调整,装置效率提高到50%,能源单耗下降到5.5度/千吨米。看来,仍没有达到水电部的规定指标。很明显是原来规划设计不合理,机组选型、安装不当和管理不善而造成的。因此,我想在这里提出几个问题。电灌
The first issue of this year’s “irrigation and drainage machinery” published by Comrade Wang Kaolin, Xuzhou City Water Conservancy Bureau, “mechanical and electrical drainage irrigation station reasonable package and water conservation and energy saving,” a paper said that the average installation efficiency of electromechanical irrigation and drainage pumping stations in Xuzhou City was 39% Energy consumption of rice is 7 degrees (greater than the Ministry of standard 5 degrees). In 6683 Taichung, supporting unreasonable 30%; after adjustment, the device efficiency increased to 50%, energy consumption dropped to 5.5 degrees / kiloton. It seems that the Ministry of Electric Power has still not reached the required targets. Obviously the original planning and design is unreasonable, the selection of units, improper installation and poor management caused. Therefore, I would like to ask a few questions here. Electric irrigation
