Abstract:An automatic condition monitoring system for circulating turbo-compressors was introduced. The structure, the key point of technology and the special features of the system were presented in detail. Centering on industrial controlling computer, the system selects signals of axial position, vibration and technical parameters as on-line monitoring signals, adopts the monitoring model of threshold value control and could realize condition monitoring, fault diagnosis and service life predication of roller bearing. The system has been applied to industrial ground successfully.
Key words: circulating turbo-compressors; condition monitoring; fault diagnosis; service life predication
