摘要

郑州新力电力有限公司200MW机组锅炉给水泵组液力偶合器主油泵传动齿轮频繁损坏

经分析认为由电腐蚀所致。采取断开轴电流通路的方法

成功解决了这一问题

并提出了进一步的防范措施。

Abstract

The transmission gears of main oil pump in hydraulic coupling of the motor-driven pump set for 200 MW unit in Zhengzhou Xinli Electric Power Co Ltd have been frequently damaged. It is believed through analysis that the cause to be electro-corrosion. This problem has been successfully solved by adopting method to cut off the path of shaft current

and preventive measures being further put forward.
