摘要
汽轮给水机组是重要的汽轮辅机之一。针对某型汽轮给水机组在调试中出现的振动偏大现象,结合机组振动测试结果,对机组的振动性能进行了细致的分析,找出了主要的原因,对此类型机组的设计和调试有一定的借鉴意义。
Feed water pump is one of important auxiliary equipments of steam turbine. In tuning up the feed pump of a steam turbine, over-vibration phenomena were found. In this paper, the vibration characteristic of the feed pump is analyzed carefully according to the vibration measurement data. It is found that the oil whip is the main cause of the over-vibration. The results provide a reference for tuning up and design of the feed pumps.
