国产200MW汽轮机低压缸偏移规律与防位移措施的研究

LP cylinder offset regularity of a N200MW steam turbine and its prevention measures

利用现场试验的测量数据,得到国产N200MW汽轮机低压缸偏移规律,通过理论分析找到该国产机组低压缸偏移的机理,设计出限制和消除这种机组低压缸偏移的防位移导向装置。实际应用表明,该装置对防止机组低压缸偏移是非常有效的。该研究成果对国产N200MW低压缸、循环水系统的设计和机组安全运行具有借鉴意义。

On the basis of the test data on the spot,the LP cylinder dynamic offset regularity and mechanism of a domestically made N200MW steam turbine were found and analyzed.A device was designed to prevent LP cylinder dynamic offset.The practical application shows that this device is very effective and may be used for reference in the LP cylinder and circulating water system de-sign and the safe operation of domestically made N200MW generating units.
