Many years of researches in the field of condition monitoring and diagnostics of piston compressors have allowed to realize modern methodology and achievements in the field of piston machines condition monitoring and diagnostics, which allows to carry out automatic real-time monitoring and diagnostics on the basis of multivariate processing of the diagnostic signals and algorithms of automatic functioning of the expert decision support system:
- real-time monitoring and diagnostics methodology is based on the measurement of the indirect processes’ parameters(acoustic vibrations), which requires not more than 5 sensors per cylinder, measurement of direct structural and thermodynamic parameters are also available;
- algorithms of the real-time decision-making expert system with an automatic identification (diagnosing in a speed rates of diagnostic signals measurement) of more than 23 malfunctions of piston compressor assemblies and their danger rates, and also issuing of purposeful prescriptions to the personnel in order to conduct compensating actions;
- scientifically grounded period of diagnosing allows to get static and dynamic errors of identification of less than 5% rate, which makes possible to carry out condition monitoring of critical equipment of the first class and other classes, as well as a production facility in general;
- the COMPACS® real-time monitoring system has a distributed parallel-serial structure, requires much less amount of sensors and cable, and, consequently, less installation and maintenance costs, provides low cost of ownership and switches piston compressor operation to the condition-monitored one, ensuring high economic efficiency of implementation..
