About the experience in operation of reciprocating compressors under control of the vibration monitoring system

摘要

The article presents the results of reciprocating compressors operation under the control of Vibration-Based Diagnostics monitoring systems, dwells upon the issues of usage of reciprocating compressors valves by various vendors and their influence on compressors' vibroactivity. An adequate evaluation of vibroactivity of piston machines is provided by the Russian regulative database on vibration parameters. Main differences of Russian and global methods of reciprocating compressors health evaluation, particularly, used frequency range, are presented in the article. It is shown that the approach laid in Russian standards on reciprocating compressors vibration regulations, ensures true-to-life assessment of reciprocating compressors assemblies and details condition. The examples given in the article confirm that the criteria of reciprocating compressors repair correctness assessment should be the machinery health, including its vibroactivity, not just mindless usage of new components purchased from the global brands. Practical examples of operation and monitoring of reciprocating compressors show that Russian developments and products, particularly, scientific-methodological and standards base of Vibration-Based Diagnostics monitoring, reciprocating compressors monitoring systems, reciprocating compressors valves are highly competitive with foreign ones, and sometimes even superior to them in parameters and characteristics, which is a positive factor under the conditions of current economic situation and import substitution policy.
