《泵站技术改造通则》指出,“泵站技术改造应充分应用现代先进的机电排灌技术,对现有的泵站进行综合技术改造”。按照这一技术要求,各地在泵站技术改造中,从全局出发,最大限度地提高泵站的装置效率η_装=η_电η_传η_泵η_管,并重点抓住了提高主泵的运行效率(η_泵)和管路效率η_管(尤其对低扬程泵站),而对提高电动机效率(η_电)却不太重
“Pumping Station Technical Reform General” pointed out that “pumping station technical transformation should make full use of modern advanced electromechanical irrigation and drainage technology, the existing pump station comprehensive technical transformation.” In accordance with this technical requirement, all over the pump station technical transformation, starting from the overall situation, to maximize the pumping station device efficiency η_ installed = η_ electric η_ η_ η_ pump η_ tube, and focus on improving The main pump operating efficiency (η_ pump) and the pipe efficiency η_ tube (especially for low-lift pumping station), and to improve the motor efficiency (η_ electricity) is not too heavy
