| description | Lubrication plays an important aspect in machinery. It seals internal leakage gaps, reduces friction
and cools components. The present investigation is intended to test the effects of lubrication to an
expander’s performance. Polyester lubricating oil grades (Grade 48 and Grade 68) were tested at
various operating conditions. The expander prototype is of the rotary mechanism with four vanes
comprising two intersecting bars. An experimental test rig was designed and built. The pressure diagram
as function of rotational angle was recorded by six pressure transducers arranged in the working
chamber, based on which the features of the expansion process of the four-intersecting-vane rotary
expander were analysed. To start with, the working fluid was compressed air, but the eventual intended
application is in a vapour compression refrigeration system. The experimental study revealed that
the rotary vane expander worked steadily at different operating conditions. The experimental results
showed that the expander flow rate was generally lower with a thinner oil (POE grade 46), whereas
the volumetric efficiency increased from 23,2 % to 27,2 %. The adiabatic efficiency decreased from
22,5 % to 18,1 % with a higher viscosity lubricating oil (POE grade 68). |
