摘要
对200MW汽轮机组高压锅炉电动给水泵变频调速进行了综合技术经济比较。液力耦合器调速给水泵变更为变频调速给水泵,节能效果显著,节电率可达20%以上。
The feasibility study of the alteration of variable frequency speed regulation motor-drive FW pump is expatiated, and the integrated technological and economic comparison is introduced. If the variable frequency speed regulation FW pump is replaced with hydraulic coupler FW pump, the power supply for station can save 20% , with greater econmic effect.
