摘　　要：被称为电厂锅炉供水"心脏"的汽动给水泵是火力发电厂关键的设备之一,其运行直接影响整个机组的安全性和经济性。对大型锅炉给水泵的轴承振动、机械密封装置、润滑油系统等几个方面进行了详细分析,着重研究了小汽轮机流动参数特性,得出了汽动给水泵寿命与流动参数的关系。通过优化流动参数,更好地提高了机组运行的可靠性﹑经济性。Steam feed pump is one of the key equipment in thermal power plant, called the ＂heart＂ of power plant boiler water supply, its operation directly affects the safety and economy of the whole unit. This paper analyzed bearing vibration, mechanical sealing device, lubricating system and so on several aspects of large boiler feed water pump in detailed, focused on the analysis of the small turbine flow parameters, so as to find out the steam feed pump life and the relationship between the flow parameter, optimized the flow parameter, improved the reliability and better economical efficiency of the unit operation..
