| 摘 要： | 对1号机组在调试过程中出现的轴承烧瓦、轴振较大、低压转子轴承金属温度偏高等问题进行分析，认为轴承自定位性能较差，汽封与转子碰磨，5号、6号轴承设计标高偏高是故障的主要原因，提出更换新瓦，控制冲转参数，降低5号、6号轴承标高等处理措施，说明处理效果，并提出相应建议。

| Abstract: | After analysis on shaft hearing buring, large shaft vibration, high temperature of low-pressure rotor hearing metal of No.1 unit during commissioning, this paper indicates that the main causes are worse shaft self-localization per- formance, the rub of the seal and the rotor, high design level of No. 5 and No. 6 shafts, proposes the settlements, such as replacement of the new bearing, turning parameter control, lowering bearing level, explains the settlements effects, and proposes the corresponding suggestions. |
