<P>PROBLEM TO BE SOLVED: To provide a system for determining a shaft misalignment in a turbomachinery train having a plurality of components with serially coupled rotating shafts. <P>SOLUTION: The system includes sensors 30A, 30B, 30C affixed to components 12, 14, 16 proximate to rotating shafts 24, 26, 28 of the turbomachinery train 10. The sensors 30A, 30B, 30C collect vibration data along an axial direction of the rotating shafts 24, 26, 28. Also provided are a frequency analyzer for generating frequency domain data from the vibration data and an analysis system for analyzing frequency components 12, 14, 16 of the frequency domain data at one times rotational frequencies of the rotating shafts 24, 26, 28 to identify a misalignment between the rotating shafts 24, 26, 28 and adjacently coupled rotating shafts 24, 26, 28. <P>COPYRIGHT: (C)2012,JPO&INPIT |
