摘要
阐述了循环水泵电机双速改造在大唐淮北发电厂的应用,介绍了改造后的试验情况,并着重对改造前后的效能和节电情况进行了分析与对比。结果表明,对循环水泵进行双速改造,不仅提高了循环水系统调节的灵活性,而且投资省,节能效果显著,降低了厂用电量,提高了经济效益,为电力企业的"节能减排"工作取得了较成功的经验,具有推广价值。
This paper described an alteration of circulating water pump motor in Huaibei power plant, after the alteration the motor speed can be shifted between two set speeds and they make some experiences to analyze and contrast something about the motor efficiency and saving power before and after the alteration. The conclusion of this paper was that pliancy of governing circulating water system was improved, and what＇s more, station auxiliary power was reduced, so that energy-profit this alteration can save is high while investment is low. This alteration is a successful experience of energy conservation and emissions reduction of power enterprises, so it is valuable to be spread.
