| 摘 要： | 通过对广西百色右江水力发电厂2#机组上导轴承摆度出现不规则进行观察和分析,发现上导滑转子与顶轴轴身发生了相对周向移动致使上导轴承摆度不规则。采取对上导滑转子现场热套加垫的临时处理方法,通过电磁加热使上导滑转子膨胀后加不锈钢垫片,以增大顶轴与滑转子间的摩擦力。经现场热套处理,2#机组上导滑轴承摆度恢复正常。

| Abstract: | The upper guide bearing of No.2 unit of Youjiang Hydropower Plant had seen abnormal run-out.According to observation and analysis,it was found that it was caused by circumferential displacement of bearing collar.The temporary treatment measure adopted is expanding the bearing collar by electromagnetic heating, then inserting stainless steel gasket,so as to increase the friction force.The bearing run-out of No.2 unit restore regular state after the treatment. |
