Rotary air compressor lubrication - developing and testing the new generation of lubricants

摘要

Modern rotary air compressors are designed to operate under more severe and extreme operating conditions than their predecessors. These place greater demands on the compressor oil, in terms of maintaining optimum lubricant performance whilst giving a longer oil life. This paper looks at the key lubricant performance requirements for rotary compressors, and gives examples of how these are tested and met by lubricating oil manufacturers such as The Shell Group (Shell), using the latest base fluid and additive technologies.
