摘 要:随着我国煤电机组综合升级改造步入“深水区”,发电厂在大量的风机和水泵已经
进行了变频调速节能改造并取得显著节能效果的情况下,“动刀”号称火电机组“心脏”的
液力耦合器调速的电动给水泵已经势在必行了。给水泵系统节能改造是一个涉及面广,技术
难度大,可靠性和控制保护要求高的系统性工程。关键是要拿出可靠性最高,改动最小,投
资最少,节能效果最好的科学合理的改造方案来。
Abstract: With the upgrading of coal units integrated into the "deep water", power plants and pump in a lot of fans have been the case of frequency control to achieve significant energy-saving and energy-saving effect, the "knife" is
