1、发电机振动原因分析及处理过程对运行中振动跟踪结果进行分析，得出以下结论1）发电机内氢气温度对励磁机振动的影响特别敏感，振动大小随着氢气温度的变化而变化2）机组无功负荷的变化，对励磁机振动的影响也较大。2 机组的无功负荷一般只保持在30Mvar左右，无功负荷升高后励磁机的振动明显增大。运行一段时间后，励磁机的外部振动再次达到0.11mm左右。根据现场的实际情况，于2004 年 3月 16 日停机小修，再次对励磁机振动进行处理。励磁机揭盖检查后在其端部增加平衡块75g，发电机 7、8 振动分别降至 0.012mm至 0.016mm，通过配重后调整氢气温度和无功负荷，运行不久以后励磁机部位的振动值又

2、上升到了0.13mm，发电机组在振动超标的情况下维持运行。32 机组 B 级检修中对励磁机振动的分析及处理文档编码:CM2H9T7F1X5 HN1R9Y4H6K1 ZY7D8L10F8E3文档编码:CM2H9T7F1X5 HN1R9Y4H6K1 ZY7D8L10F8E3文档编码:CM2H9T7F1X5 HN1R9Y4H6K1 ZY7D8L10F8E3文档编码:CM2H9T7F1X5 HN1R9Y4H6K1 ZY7D8L10F8E3文档编码:CM2H9T7F1X5 HN1R9Y4H6K1 ZY7D8L10F8E3文档编码:CM2H9T7F1X5 HN1R9Y4H6K1 ZY7D8L10F8E3文
