摘　　要：针对某660 MW电厂#3机组3B汽动给水泵推力盘检修后安装不到位,使平衡鼓与平衡座装配间隙未达到厂家设计值,导致3B汽动给水泵运行中平衡鼓与平衡座发生摩擦,引起3B汽动给水泵轴承振动波动大。对此,文中对其进行分析及处理。For a 660 MW power plant#3 unit 3B steam feed pump thrust disc after maintenance installation is not in place,so that the balance drum and balance seat assembly gap does not reach the manufacturer's design value,resulting in 3 steam feed pump operation balance drum and balance seat friction,causing 3B steam feed pump bearing vibration fluctuation.In this paper,it is analyzed and processed.
