METHOD AND SYSTEM FOR PERFORMING ANALYSIS OF THE CONDITION OF THE ROTATING PART OF THE MACHINE

摘要

A method of operating the device for performing analysis of the state of a part of a machine rotating at rotational speed (f V) is proposed. It contains stages in which a first digital signal (S, S, S) is received, depending on mechanical vibrations occurring due to the rotation of said part ; analyzing the first digital signal so as to detect peak amplitude values (A) over a finite period of time (T), said finite period of time corresponding to a predetermined number (R) of revolutions of the rotational part; moreover, the predetermined number (R) of turns corresponds to at least one revolution of the controlled rotational part; set multiple ranges of amplitudes, and each range of amplitudes corresponds to the frequency of occurrence of a peak greater than one peak per revolution; sorting the detected peak amplitude (Ap) values into the respective amplitude ranges so as to reflect the appearance of the detected peak amplitude (Ap) values in a plurality of amplitude ranges; and set the values of the peak amplitude (A) for the detected peaks having a frequency of occurrence of approximately N peaks per revolution, and the mentioned value of the N frequency of occurrence is a number greater than one.
