CONTROL OF THE TECHNICAL CONDITION OF RECIPROCATING MACHINES BASED ON THE ANALYSIS OF THE UNEVEN ROTATION OF THE SHAFT
(pp. 58-62)

Abstract. The question of the use of vibroacoustic control to assess the technical condition of piston machines is considered. In most cases, the vibroacoustic method of non-destructive testing is based on the analysis of the vibration spectrum of the controlled equipment. Since the angular velocity of the piston machine shaft is not constant, the shape of the spectrum also changes, which complicates the application of this method of non-destructive testing. A hypothesis is proposed about the possibility of determining the technical condition of piston-type machines, based on the measurement of deviations of the angular velocity of the shaft depending on the angle of its rotation, without the use of spectral analysis, experimental measurements of the angular velocity of the shaft of a piston machine were carried out using a measuring device based on an absolute magnetic encoder. Experimental data have been obtained to identify emerging defects of the piston machine.

Keywords: non-destructive testing, piston machine, angular velocity, encoder.
