Condition monitoring ensuring profound diagnostics of the assemblies and mechanisms of reciprocating equipment and first of all compressor units with reciprocating compressors and internal combustion engines is one of the most important problems solvable through the diagnostics by vibration signal parameters.
Development of the methodology and systems for reciprocator condition monitoring is an actual problem.
The paper presents the methodology for monitoring, gives definition of the following terms: condition monitoring of the units, technical diagnosing of the unit, technical diagnosis, diagnostic feature. In addition, it presents the guidelines for monitoring system construction and specifies the main parameters characterizing and accompanying reciprocating compressor work.
For equipment condition monitoring the following parameters are used (depending on diagnostic tasks): vibration acceleration, vibration velocity, vibration displacement, temperature, pressure, radial clearance, current consumption, shaft speed, fluid (condensate) level, the signal of acoustic emission sensor, the parameters of alternating/direct current and voltage.
