APPLICATION OF NOISE SOURCE IDENTIFICATION TECHNIQUES AND RESULTANT MODIFICATIONS ON A RECIPROCATING COMPRESSOR.

Author(s) : BLASS J., QUELLHORST T., WILLIAMSON G.

Summary

THE ARTICLE APPLIES TO A 15 HORSE-POWER, THREE-CYLINDER, SEMI-HERMETIC COMPRESSOR OF CONVENTIONAL DESIGN. THE MAJOR NOISE SOURCE WAS IDENTIFIED BY ANALYSIS OF THE VIBRATION SIGNAL IN THE TIME DOMAIN. IT WAS FOUND TO EMANATE FROM THE DISCUS-TYPE DISCHARGE VALVE. AS THE VALVE ASSEMBLY WAS TO BE REDESIGNED FOR PERFORMANCE IMPROVEMENT, NOISE CONTROL WAS ALSO CONSIDERED. VALVE IMPACT NOISE DURING BOTH OPENING AND CLOSING WAS REDUCED BY INCREASING GAS FLOW AREA, LIGHTENING THE VALVE DISC, AND STIFFENING THE RETAINING BRIDGE. THE NOISE REDUCTION WAS 4 DBA ASSOCIATED WITH AN ENERGY EFFICIENCY RATIO INCREASE OF 1.5% AND A CAPACITY INCREASE OF 2.0%. D.W.H.
