660 MW机组汽动给水泵组振动异常处理

Handling of Abnormal Vibration of 660 MW Turbine Driven Feed Water Pumps

伴随电力供应的市场化发展,基于市场经济杠杆调控,如何降低运行成本已然成为各大电力企业所面临的一项重要问题。在此背景下,临界汽轮发电机组在电力企业中得到广泛推广,对其中用以供给锅炉用水的汽动给水泵也提出了越来越严格的要求。文章以660 MW机组汽动给水泵组为研究对象,阐述了660 MW机组汽动给水泵组相关优势特征,分析了660 MW机组汽动给水泵组振动异常原因及处理。

With the development of marketization of power supply,how to reduce the operating cost has become an important issue for major power enterprises based on the lever regulation of market economy.Under this background,critical turbo-generator set has been widely popularized in electric power enterprises,and more and more strict requirements have been put forward for steam feed pump which is used to supply boiler water.Taking the steam feed water pump set of 660 MW unit as the research object,this paper describes the relevant advantages and characteristics of the steam feed water pump set of 660 MW unit,analyzes the causes and treatment of abnormal vibration of the steam feed water pump set of 660 MW unit.
