Investigação da confiabilidade em rotativos para sistemas ácidos nas dimensões de gestão, tecnologia e fatores humanos.

Abstract

This article intends, through the investigation of the cause of events in the dimensions of man, management and technology, to propose an improvement in the Average Time Between Failures (MTBF) of rotating equipment and consequently increase the reliability of production systems. For a more specific study, centrifugal pumps were selected, used in an industrial plant chemical, located in the petrochemical complex in Bahia, specifically that process sulfuric acid (H2SO4). As a methodological contribution, Fault Tree Analysis (FTA) and Criticality and Mode Analysis were used Effect of Failures (FMECA) as tools for the study of reliability in investigation. The result demonstrates that the root causes of failures in bombs were due to a culture of guilt present at operational levels and disseminated by management levels, in which the search for the culprit was aimed by stopping the machine, and not looking for the source of the problem, in order to to create a more efficient inspection routine. Improvements were proposed with the implementation of joint monthly meetings between operation, maintenance and management and for leaders the board provided training on leadership and management, in order to improve interpersonal relationships and integration with the team.
