DIAGNOSIS OF SLIDES IN ROTARY COMPRESSORS USING ACOUSTIC EMISSION (AE) TECHNIQUE.

Author(s) : SATO K.

Summary

FIRSTLY, AE CHARACTERISTICS IN NORMAL COMPRESSORS WITHOUT DEFE CTS ON SLIDING SURFACE WERE INVESTIGATED BY AE MONITORING TEST. INVESTIGATION OF THE GENERATING MECHANISM FOR NORMAL AE SIGNALS SHOWED THAT THEY ARE CAUSED BY BATTING PHENOMENON OF A VANE IN VANE-SLOT OF CYLINDER. NEXT, IN EXPERIMENTAL TEST OF COMPRESSORS WITH ARTIFICIAL DEFECTS OF ROTATING SLIDES AND IN RUNNING TEST UNDER SEVERE CONDITIONS, BURST AND/OR CONTINUOUS TYPE AE SIGNALS CAUSED BY DEFECTS AND METAL-CONTACT AMONG SLIDING PARTS WERE DETECTED.
