Fatigue Degradation Evaluation of Details and Substructures of Dynamic Equipment in Operation by Vibration Parameters
The vibration monitoring of dynamic equipment in operation at oil refineries was carried out with the help of stationary monitoring systems for the technical condition and automatic diagnostics of COMPACS® and analysis of changes in the technical condition of the units. It is established that in some cases fatigue degradation and subsequent destruction of parts occur in stages. In this case, the vibration emissions reflect the stages of degradation. The developed technique for controlling emission amplitudes and intervals between vibration emissions allows us to detect in a timely manner the presence of a process of stage-by-stage degradation of parts in the operating unit, to warn personnel, to provide preparation for repair work and to prevent emergency situations.
Keywords: vibration monitoring, rolling bearing, stage-by-stage degradation, amplitude, ejection, interval.
