离心压缩机开机问题

Reply #72017-04-05

本帖最后由 haiyuedzh 于 2217-3-28 16:45 编辑 1、透平开机时候，是先暖管还是先盘车？ 2、透平的轴封蒸汽是怎么一回事儿？何时投投轴封蒸汽？ 3、暖机和轴封蒸汽的投投先后有什么联系？ 4、最小可调转速是什么？ 5、压缩机开机最容易出现什么问题？最应该注意哪些地方？ 6、轴封蒸汽与透平蒸汽进入透平是同一流程吗？

本帖最后由 shishiazhang 于 8sh17-3-29 2:sh9 编辑 1、透平开机时候，是先暖管还是先盘车？先暖管后暖机；冷态暖管暖机均不盘车（凝汽式透平） 2、透平的轴封蒸汽是怎么一回事儿？何时投投轴封蒸汽？凝汽式汽轮机需要投轴封蒸汽保证负压的建立，背压式没有 3、暖机和轴封蒸汽的投投先后有什么联系？暖机前可能不需要投投轴封蒸汽，暖机是必须投投为了尽快建立负压 4、最小可调转速是什么？转速调节范围最低转速 5、压缩机开机最容易出现什么问题？最应该注意哪些地方？振动高，喘振 6、轴封蒸汽与透平蒸汽进入透平是同一流程吗？轴封蒸汽是其密封作用的，透平蒸汽驱动透平，不是同一流程
