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.
