描述
电动机未停机之前，用测振表检查各部振动情况，对于振动较大的部位按垂直水平轴向三个方向详细测试振动数值，如果是地脚螺丝松动或轴承端盖螺丝松动，则可直接紧固，紧固后在测其振动大小，观察是否有消除或减轻，其次要检查电源三相电压是否平衡，三相熔丝是否有烧断现象，电动机的单相运行不仅可以引起振动，还会使电机的温度迅速上升，观察电流表指针是否来回摆动，转子断条时就出现电流摆动现象，最后检查电机三相电流是否平衡，发现问题及时与运行人员联系停止电机运行，以免将电机烧损。如果对表面现象处理后，电机振动未解决，则继续断开电源，解开联轴器，使电机与之相连的负载机械分离，单转电机，如果电机本身不振动，则说明振源是联轴器没找正或负载机械引起的，如果电机振动，则说明电机本身有问题，另外还可以采取断电法来区分是电气原因，还是机械原因，当停电瞬间，电动机马上不振动或振动减轻，则说明是电气原因，否则是机械故障。检查气隙是否均匀，如果测量值超标，重新调整气隙。检查轴承，测量轴承间隙，如不合格更换新轴承，检查铁心变形和松动情况，松动的铁心可用环氧树脂胶粘接灌实，检查转轴，对弯曲的转轴进行补焊重新加工或直接直轴，然后对转子做平衡试验。打风机电机大修后试运行期间，电机不仅振动大，而且轴瓦温度超标，连续处理几天后，故障仍未解决。我班组人员在帮助处理时发现，电机气隙非常大，瓦座水平也不合格，故障原因找到后，重新调整各部间隙后，电机试转一次成功。把基础上四个地脚螺栓全紧固，电机的振动值仍然超标，这时检查轴伸上装的联轴器是否和轴肩靠平了，如不平，轴伸上多余的键产生的激振力会引起电机水平振动超标。这种情况振动值超得不会太多，往往和主机对接后振动值能下降，应说服用户使用，二极电机在出厂试验时根据GB10068–2006在轴伸键槽内装在半键。多余的键就不会额外增加激振力。如需处理，只需把多余的键截去多出长度的一般即可。
