MATHEMATICAL SIMULATION OF LUBRICATION CONDITIONS IN ROTARY VANE COMPRESSORS.

Author(s) : PICKSAK A., KRUSE H.

Summary

DUE TO THE CENTRIFUGAL FORCES, ROTARY VANE COMPRESSORS SHOW AT HIGH SPEEDS VANE TIP FRICTION LEADING TO LOW MECHANICAL EFFICIENCIES. THEORETICAL MODELS WHICH ARE BASED ON THE HYDRODYNAMIC LUBRICATION THEORY TO DETERMINE THIS FRICTION LOSS BETWEEN THE VANE TIP AND THE CYLINDER HAVE BEEN EARLIER DEVELOPED AND PRESENTED. A NEW MODEL HASBEEN DEVELOPED FOR DIFFERENT TYPES OF VANE TIPS AND DIFFERENT SHAPES OF THE CYLINDER. CALCULATIONS DEMONSTRATE THAT IT IS POSSIBLE TO DECREASE THE VANE TIP FRICTION BY APPROXIMATELY 10%. AN OBSERVED CHATTERING PHENOMENON OF THE VANE AT LOW SPEED OPERATION CAN BE PREDICTED BY CALCULATION AND AVOIDED BY SELECTION OF CERTAIN SHAPES OF THE VANE TIP.
