摘要

提高电动给水泵效率

可给发电厂带来更好的经济效益。对邯郸热电公司200MW机组配液力偶合器电动给水泵单耗高原因进行综合分析

提出了降低偶合器滑差等技术措施

改进后取得了较好的效果。

Abstract

The enhancement of motor-driven feed-water pump’s efficiency can bring more better economic benefits for the power plant. comprehensive analysis of causes leading to high specific consumption of the motor-driven feed-water pump provided with hydraulic coupling for 300 MW unit in Handan Thermal Power Plant has been carried out

putting forward technical measures for decreasing slip of the said coupling. After retrofitting

comparatively good economic benefits have been obtained.
