摘要
通过对岭澳核电站1号机组励磁机11号轴瓦损坏形式的分析,找到了引起损坏的根本原因,提出了解决方法。通过对发电机大端盖结构的分析研究,得出了大端盖充压后变形导致11号轴承负荷增高从而引起温度高的结论以及相应的解决方案。
On the base of analyzing the type of exciter No. 11 bearing white metal damage, the root cause and its solution are found, and no damage was found on bearing white metal in the later time. On the base of analyzing the structure of the generator end bracket, It is pointed out that when the generator frame is full of pressed gas, the end bracket will deform, that result in the load on No. 11 bearing increase, as a result causes the bearing temperature high, and then give its soultion.
