One of the newer technologies involves twin screw compressors. This article will look at service-related aspects of such a unit. The screw compressor is a positive-displacement rotary mach-ine.

Conventional compressor bearings - for example, leaded-bronze, rolling element or bi-metal bushings - will be significantly affected by wear in marginally lubricated environments at bearing locations ...

A good digital multimeter (DMM) is key to diagnosing compressor problems in general. For instance, in a previous article (May 15 issue of The NEWS) we discussed using the DMM to read suction and ...

Polymer bearings incorporating a PTFE-based running surface were viewed as a step forward in scroll compressor performance when they were initially introduced around three decades ago. These polymer ...
