Abstract

In developing rotary vane compressors for compressed air or refrigerating systems the biggest challenges are predicting of friction forces and the overcoming wear between vane and roller (stator) surfaces. In this review compressor energy balance in different operating conditions and effect of vane mass and compressor geometry are observed. Also rotary vane compressor friction and wear investigations in refrigeration systems are observed, influence of several vane surface coatings and lubrication is investigated. Different outlet pressures and revolution speeds on test compressor indicated power increase with rising discharge pressure and revolution speed. The reduction compressor speed from 1500 RPM to 1000 RPM would decrease the effects of friction to almost twice. It’s important to use coatings like TiN or WC/C, which have good and very good, wear resistance properties in order to reduce friction and wear on rotary vane friction pair.

Keyword(s): Rotary-vane compressor, vane, friction, wear, energy saving, coating.
