Monitoring a centrifugal compressor through vibration analysis

Abstract

The objective of this project, for the end of the master’s studies in mechanical engineering, is the monitoring of the behavior of centrifugal compressors of natural gas production using vibration analysis. In this project, we acquired the raw signal from the sensors mounted at the journal bearing, which was converted from an electric current to the digital domain using appropriate technologies. This signal was recorded in tabular form, then used to analyze vibration using MATLAB software, and then obtained figures, numbers and spectra that have been used to make decisions about compressor maintenance while retaining this experience to operate in the future.
