Basic principles of technology for real-time diagnostics and monitoring of piston machines

Technology for real-time diagnostics and monitoring of piston machines is based on collection and processing of data which are to provide detection of defects and malfunctions of piston machines with specified detalization and accuracy, as well as their danger rates.

The technology implementation comprises usage of vibration-acoustic signal structure models in case of occurrence of defects and failures of assemblies and details of piston machines, combination of diagnostic features of failures and signal parameters in case of failure occurrence, ways of vibration-acoustic signal processing and evaluation system for the vibration-acoustic signal parameters.

One of the practical ways of the technology implementation and solutions of piston machines diagnostic and monitoring tasks is introduction of the given solutions which form a database connecting diagnostic features of failures and condition of piston machines’ details into functioning algorithms of the diagnostic and monitoring system COMPACS^®.

The presented methodology of monitoring and diagnostics based on measuring the parameters of secondary processes (vibration-acoustic oscillations) allows to implement the algorithms of the real-time expert system for decision-making with automatic detection (diagnosing in time with diagnostic signals’ change) of more than 20 malfunctions of assemblies, such as piston compressors of hazardous production facilities, their danger rates and issuing prescriptions to the personnel for the required maintenance actions.
