Abstract

PURPOSE: To display conspicuously properties of vibration at every measurement position and the entirety by displaying a vibration amplitude value and frequency by bar graphs with discriminative abnormal vibration marks, by digitally processing a vibration detection signal by a data processor.
CONSTITUTION: Vibrations of rotation axes of turbine rotors 1W3 and generator rotor 4 are detected by vibration detectors 6..., vibrometer 7, etc., provided to bearings 5.... Their detection signals and another detection signal obtained by rotation speed detector 31 are converted into digital signals, needed digital processing of which including frequency spectrum analysis is performed by data processor 9. As a result, vibration amplitude and vibration frequency at every measurement position are conspicuously displayed by bar graphs 11..., and 17... together with abnormal vibration display marks 12..., 18..., etc., so that properties of vibration at every measurement position and the entirety can be observed at a look.
