APPARATUS AND METHOD FOR DIAGNOSIS AND ANALYSIS OF TORSIONAL VIBRATION

摘要

The present invention relates to an apparatus and a method for diagnosing and analyzing the torsional vibration of stream turbine shafting. The apparatus comprises a non-contact magnetic probe for measuring the RPM of a turbine generator, a smart sensor which converts a pulse signal outputted from the magnetic probe and outputs the RMP, and a torsional vibration analyzer which receives the signal, evaluates the separation condition of natural frequency, and evaluates the stress and lifespan of total shafting.
