Safety level at piston compressors units operation is determined by the reliability of their condition control, trustworthiness and timeliness of malfunctions and their causes detection. Today there are a lot of technical means which are developed and produced for monitoring and diagnostics of piston compressors and generally offered by the foreign companies. However, a question of adequacy of carried-out measurements to real conditions of piston compressors is opened.
The article reveals criteria of the equipment condition. As a rule, there are four categories of such conditions: "good", "acceptable", "measures required" and "unacceptable".
The article dwells upon the choice criteria of diagnostic signals for condition monitoring, gives the sources of a vibroacoustic signal.
The methodology and algorithms of piston compressors diagnosing are revealed. The distinctions between systems for real-time monitoring and on-line monitoring are listed.
