| 摘 要： | 某核电厂立式水泵配套电机存在两径向方向振动差异大、启机后振动缓慢上升的振动现象，为解决该问题，本文利用频谱分析、固有频率分析、相位分析等方法进行故障诊断，判断出该配套电机存在结构共振、转子热弯曲、动不平衡的耦合问题，并最终通过调整螺栓及现场动平衡方法成功解决了振动问题。

| Abstract: | In a nuclear power plant, the vertical pump motor has a large vibration difference between the two radial directions, and the vibration phenomenon slowly rises after the start. To solve the vibration problem, this paper uses methods such as spectrum analysis, natural frequency analysis, and phase analysis to diagnose the fault. It is found that the matching motor is with the coupling problem of structural resonance, rotor thermal bending and dynamic unbalance, and the vibration problem is solved by adjusting the bolt and the on-site dynamic balance method.? |
