Safe operation of the compressor units with reciprocating compressors (CU with RC) operating on explosive and noxious gases is possible only by continuous monitoring of their technical condition.
At most enterprises of oil-refining industry CU with RC are almost beyond their service life, and it is necessary to make an examination of industrial safety in order to prolong their service life. In addition, schedule-based preventive maintenance and repair are not economically feasible and efficient, and more than once it was proven in practice and examples of centrifugal equipment. The only way out is equipping of CU with RC with condition monitoring systems using various methods of nondestructive testing and process variables and transition to operation, maintenance of reciprocating compressors by their actual technical condition. Therefore, the development of methodology and systems for condition monitoring of CU with RC is a topical problem.
The article gives scientific definitions of condition monitoring, technical diagnostics, technical diagnosis, diagnostic feature; it presents the principles of monitoring system structure, data collection, data analysis and processing, time selection of the signals, spectral analysis, envelope analysis, trends, pattern identification, emergency shutdown and presentation of monitoring results.
