The experience in operation of real-time condition monitoring of reciprocating compressors

The basis of reliable and resource-saving machinery operation of potentially hazardous productions is real-time condition monitoring of facilities. This is proved by a long-term experience of using monitoring systems on “Lukoil” refineries.  The reciprocating compressors (RC) condition is determined by the number of parameters (absolute and relative vibration of assemblies and RC details; temperature of the assemblies, oil and compressed gas; gas pressure in decreasing space, in suction and discharge manifolds).

Any monitoring system is based on the following efficiency criteria:

• Providing safety measures for reciprocating compressors maintenance;
• Timely system response to fast-evolving and potentially hazardous defects and failures of assemblies and details;
• Minimum costs for the system are determined by the system’s architecture and number of measuring channels.

The results of many years of the research reveal that absolute vibration parameters change due to degradation of assemblies and details structural parameters. The distance between interacting and coupled details determining the machinery condition increases as a result of degradation. Therefore, the absolute vibration monitoring is a common technique for accident prevention and diagnostics of reciprocating compressors.
