FONTES Ingeniería wear reliability accelerated tests Hermetic reciprocating compressor T he refrigerants being used in vapor compression processes have specific thermodynamic properties, which are decisive for the perf ormance of the compressor of the system. The Montreal and the Kyoto protocols initiated a discussion of alternative refrigerants, which lead to new requirements of the compressor. The reliability of reciprocal compressors has become a leading field for com pressor research. One of the main tools in the reliability field is accelerated degradation/life testing (AD T or ALT ). These tests are designed to provide life estimates or to define lower bounds of product/parts reliability at shortened time periods . The objective of this paper is to discuss the literature on accelerated life testing of reciprocating hermetic compressors , focusing on the wear of mechanical components. Several test methodologies are discussed as well as the procedures used to wear quantific ation . It is noted that there are numerous test methodologies . This fact can be attributed to the lack of standardization updated. Most authors have been focused the tests development to assess the scuffing occurrence in components. The evaluation of wear ( qualitative and quantitative) is carried through optical microscopy techniques , scanning electron microscopy , surface roughness, physical - chemical analysis of the oil and electric power consumption . Test methodologies are presented based on critical analy sis of the existing literature and the current scenario of refrigerants and lubricants development. 2016 artículo científico 1518-1634 https://www.redalyc.org/articulo.oa?id=481554867010 en http://www.redalyc.org/revista.oa?id=4815 HOLOS application/pdf Instituto Federal de Educação, Ciência e Tecnologia do Rio Grande do Norte HOLOS (Brasil) Vol.4 |
