The report deals with the problems of vibration analysis of machine equipment on the basis of the analysis of vibration parameter trends. Main modern methods of machine vibration analysis are based on the evaluation of vibration parameters and on the analysis of vibration signal spectra.
Harmonic analysis of the spectrum usually requires knowledge of an exact construction of a machine; and existing methods of vibration analysis and prediction of technical condition do not take into consideration harmful effect of the human factor. Reliability of evaluation of machine equipment condition can be increased considerably by the use of the laws of processes of destruction and operability loss.
The processes of pump-and-compressor unit degradation were researched at a number of Russian refineries by means of the COMPACS® stationary systems for vibration monitoring. The researches concerned showed that rates of operability loss differ at various machine assemblies.
