Online, Continuous Monitoring Of Mechanical Condition And Performance For Critical Reciprocating Compressors.
MetadataShow full item record
This paper outlines the typical problems seen in reciprocating compressors and shows that the existing type of monitoring systems, consisting of vibration level, rod drop, rod runout, and valve cap temperatures, often misses many of them. The advanced compressor monitoring system, which uses dynamic compressor cylinder pressure, directly targets these areas. This system not only provides the information available in the old type monitoring system, but provides much more information concerning the compressor’s loading, performance, and efficiency. Operators and maintenance personnel will now have much more information for critical decisions concerning letting a compressor continue in service or shutting it down to help prevent further damage. A point by point discussion of the type of data available form such a system and diagnostic information provided by each parameter is provided. Finally, several examples are presented showing the use of this type of advanced continuous monitoring system on a hydrogen compressor in a refinery setting.
