Análise de acidente em acoplamento de grupo motor gerador: estudo de caso do uso das ferramentas de qualidade numa empresa de cogeração

Abstract

In this work, maintenance management was used to improve performance in machinery and quality tools to subsidize and enhance the analysis of an incident occurred in a cogeneration company. This allowed such mechanisms to identify the causes that caused the flange breaking responsible for coupling alignment measurement. To do so, it was necessary to analyze the importance of maintenance management and identify which quality tools capable of identifying the triggering event. The result was an erroneous projection of the measuring flange and the lack of a safety device that allowed a collision in the same and, thus, causing its breakage and interrupting the tests.
