Summary

A SMALL SCROLL HERMETIC HELIUM COMPRESSOR CAPABLE OF COMPRESSING HELIUM GAS TO THE PRESSURE RATIO OF 20 IN A SINGLE STAGE WAS DEVELOPED. MAIN FEATURES ARE: 1) ITS DISCHARGE CAPACITY CAN BE VARIED FROM 7 TO 20 NM3/H BY CHANGING DRIVING MOTOR FREQUENCY FROM 30 TO 80 HERTZ ; 2) THE OVERALL ADIABATIC EFFICIENCY SHOWED 72-79% UNDER THE PRESSURE RATIO RANGE OF 11-20 AT 60 HERTZ USING AN OIL INJECTION COOLING DEVICE.
