摘要
阳江核电站1号机组低压安注泵/安全壳喷淋泵电机在调试期间,4台电机均出现不同程度振动超标情况,为解决该型号电机振动的共性问题,电厂采用根本原因分析法对电机振动原因进行逐项分析。通过增强电机强度、改变电机定转子间隙、更换轴承配合形式等方法并结合频谱分析,最终解决了电机振动超标问题。通过根本原因分析法及试验,解决了该型号电机设计中电机支撑板刚度不足、轴承选型搭配不合理、转子共振等问题,为后续同型号电机生产提供了指导。本文主要介绍了针对电机振动高的处理过程与结果,对该类型电机振动的原因进行了深入分析。
Yangjiang Nuclear Power Station unit 1 safety injection pump-motor, the motor occurred with high vibration during the trial process. In order to solve the common problem of the motor vibration of the model, the root cause analysis method was used to analyze the motor vibration. The problem of excessive motor vibration was virtually solved by increasing the motor strength, changing the motor stator and rotor clearance, replacing the bearing form, and meanwhile combining with spectral analysis. During the motor design, problems such as insufficient stiffness of motor support plate, inappropriate lectotype of bearing, resonance of rotor has been solved by root cause analysis and the related experimental. This paper described the process and result of the high vibration of motor, and analyzed the root-cause of motor vibration.
