摘　　要：针对北仑600 MW 2号机组启动中造成轴向位移异常的各种原因进行了分析,分析论证认为,推力轴承本身存在的缺陷是产生轴向位移异常的主要原因,停机检查,发现并解决了推力轴承本身存在的缺陷,并提出了今后的应对措施。The abnormal axial displacement of Beilun 600 MW steam turbine that occurred when the unit restarted up after having shut down according to dispatching orders is analyzed. After demonstration it is considered that the abnormal axial displacement was the result of the defect in the thrust pad. By shutting down and checking, the defect in the thrust pad was found out and resolved. The abnormal phenomenon was eliminated, and countermeasures are put forward.
