Abstract

Observations of cavitation damage within a lubricated compressor system is studied experimentally. Components from field studies are examined and in particular within high carbon materials operating within a refrigerant/oil environment. Typical experimental analysis is used to observe cavitation erosion features such as SEM, light-microscopy and light-interferometer. Bubble generation and properties are studied theoretically to characterise the wear mechanisms and provide a basis for predictive modelling. An experimental test-rig is used to study bubble characteristics within fluids to compare the theoretical analysis and practical in-service results from the compressor system. Using an ultra-sonic methodology and high-speed camera techniques the bubbles are observed within the working fluids. Results from the experimental studies and theoretical analysis are presented with discussion concerning the bubble generation and cavitation erosion wear mechanisms.
