Vibration analysis and treatment of steam turbine for Unit 3 feed-water pump A in Zhanjiang Power Plant

叙述了湛江发电厂 3号机组A汽动给水泵汽轮机 2号瓦振动问题的分析及处理的整个过程 ,指出造成 2号瓦振动大的主要原因是不平衡及轴瓦刚性差。解决的办法是对转子进行动平衡和更换轴瓦。

This paper presents the vibration analysis and treatment of No.2 bearing of the steam turbine for Unit 3 turbine driven feed water pump A in Zhanjiang Power Plant. It is pointed out that the main causes of the vibration are rotor unbalance and poor bearing stiffness, solutions for which is to make dynamic balancing of rotor and replace the bearing.
