立式凝结水泵电机振动大的原因分析与处理

Vertical condensate pump motor over-vibration cause analysis and treatment

某电厂#5机组B凝结水泵电机在切换运行时振动严重超标,但泵振动值极小,通过振动诊断分析找到电机振动超标的根源在于泵的橡胶轴承、轴套出现严重磨损,采取了相应的处理措施,解决了电机振动大的问题。

A power plant's unit No. 5 condensate pump motor B is over-vibrating while switch operation. By vibration analysis,over-vibration is caused by heavy wear of rubber bearing and shaft sleeve. Treatment measurements were carried out accordingly. Motor over-vibration was eliminated.
