汽轮机不同配汽方式下，机组轴瓦温度和轴振动情况存在明显的差异，通过建模对喷嘴配汽转子受力情况进行理论分析，得出不同配汽方式下转子受力特点。针对哈汽CLNZK660型汽轮机不同喷嘴配汽方式下轴瓦温度和轴振动变化诊断研究，验证理论分析，定性总结出不同喷嘴配汽方式对轴瓦温度和轴振动的影响规律，进而给出合理选择配汽方式的方法与经验，对汽轮机组实现顺序阀调节提供一定的工程应用价值。

Turbine bearing-pad temperature and shaft vibration have significant diversities on different nozzle-steam distribution, through modeling analysis of rotor-load; get the rotor-load characteristic on different nozzle-steam distribution. Aimed at the Diagnostics of bearing-pad temperature and shaft vibration change on nozzle-steam distribution of CLNZK660 turbine of HTC, verify the theoretical analysis, and summarized the laws of different nozzle-steam distribution’s influence on bearing-pad temperature and shaft vibration qualitatively, then given the reasonable selection method and experience of nozzle-steam distribution, to provide the engineering application value to get the turbine to achieve the sequence valves adjustment.
