Abstract
A manutenção centrada na confiabilidade (MCC) trata-se de uma abordagem que tem foco na prevenção de falhas, cujas consequências geram problemas de maior gravidade. Esse método tem sido empregado na gestão da manutenção em diversos setores industriais. No setor alimentício, as embaladoras a vácuo têm um papel de extrema importância no processo produtivo, pois garantem a selagem e conservação dos produtos. Na empresa avaliada, as embaladoras a vácuo apresentam acentuado histórico de falhas, revelando que a atual metodologia de manutenção não atende as condições esperadas para estes equipamentos. O objetivo deste trabalho é aplicar a metodologia de manutenção centrada na confiabilidade em embaladoras a vácuo de uma empresa do setor alimentício, visando melhorar os índices de confiabilidade, de disponibilidade e os custos. Para tanto, os passos metodológicos seguiram o seguinte desdobramento: (i) seleção do sistema e coleta de informações, (ii) análise dos modos e efeitos de falha (iii) seleção de funções significantes (iv) avaliação de atividades aplicáveis(v) avaliação de efetividade das atividades. A aplicação da manutenção centrada na confiabilidade permitiu aplicar melhorias em exploração da função da máquina, uso do histórico do setor, conhecimento das falhas e aumentou o índice de confiabilidade e disponibilidade. Os custos de manutenção foram diminuídos em torno de 55%.
Reliability-centered maintenance (RCM) is an approach that focuses on failure prevention, its consequences generate more serious problems. This RCM method has been usedin the management of maintenance in several industrial sectors. In the food sector, vacuum packaging machines play an extremely important role in the production process, as they guarantee the sealing and conservation of products. In this study, vacuum packers have a long history of failures in the company, revealing that the current maintenance methodology does not meet the conditions expected for this equipment. The objective of this work is to apply the RCM methodology in a vacuum packaging machines of a company in the food sector, aiming to improve the reliability, availability and costs. The methodological steps followed the following breakdown: (i) system selection and information collection,(ii) analysis of failure modes and effects (iii) selection of significant functions (iv) evaluation of applicable activities(v) evaluation effectiveness of activities. The application of maintenance centered on reliabilityallowed improvements to be made in the The Journal of Engineering and Exact Sciences – jCEC2 machine's function exploration, in the use of thesector's history, in the knowledge of failures and to increase the reliability and availability index. Maintenance costs were reduced by around 55%.
