干气密封이二级失效과 축이동의 관계

저희 회사의 기자기 동안 압축기 저압실린더 비드라이브드 엔드의 干气密封二级失效，分析原因为二级静环卡涩导致。二级密封失效的同时轴位移在7微米的范围内波动，请问两者有关吗？这种情况的轴位移波动的原因是什么？

기억에 남는 幰气密封的轴位移范围比较大，只要压缩机的轴位移在报警范围内，应该不会损坏 � word.

축위동7 微米不是导致二级静环卡涩的原因

정환은 무엇을 의미하나？ 정环本来就是固定不动的，何来卡涩一说？干气密封动静环是不接触的，之间有一层有刚度的气膜撑开，不存在卡涩的问题，运转中，动静环如果接触了，动压槽会被磨坏，那肯定就废了，开车前，二级密封气打开了吗？压力流量正常吗？也可能是是轴位移导致的密封损坏，因果弄反了吧！至于轴位移为何会波动是否进气量、出气量有波动，出现了喘振之类的问题造成转子不平衡？另外这压缩机是检修后试车但没有检修就开车？
