Resumo: | The purpose of this article was to define the most appropriate maintenance strategy for a centrifugal pump (preventive, predictive, corrective or emergency), based on reliability calculation. The research method was the quantitative modeling, applied in a petroleum plant. The study may contribute to the development of a strategic model for the management of the industrial plant maintenance. In the company's information system, records of eleven years have been gathered on times between failures and times for repair of the equipment. These times were modeled by probability distributions. From the results obtained were calculated Reliability and Maintainability functions R(t) and M(t). By combining their expected values (MTBF and MTTR), Av availability was calculated. The figures for MTBF, MTTR and Av were respectively 3,936 hours, 133 hours and 96.73%. The most likely shape factor of the Weibull distribution which modeled the time between failures was 0.69. So, it was possible to affirm that the pump is in the infant mortality phase. The theoretical framework of RCM indicated corrective maintenance as the strategy for the item. This strategy aims to eliminate the defects of equipment design, reinforce items that usually break and remove the causes of the failures. |

O método de pesquisa foi a modelagem quantitativa, aplicada em uma planta petrolífera. O estudo pode contribuir para o aprimoramento de um modelo estratégico para a gestão da manutenção industrial da planta. Foram levantados, no sistema de informações da empresa, registros de onze anos dos tempos entre falhas e dos tempos para reparo do equipamento. Estes tempos foram modelados por distribuições de probabilidade. A partir dos resultados obtidos, foram calculadas as funções Confiabilidade R(t) e Mantenabilidade M(t). Pela combinação de seus valores esperados (MTBF e MTTR), foi calculada a disponibilidade Av da bomba. Os valores para MTBF, MTTR e Av foram respectivamente 3.936 horas, 133 horas e 96,73%. O fator de forma mais provável da distribuição de Weibull que modelou o tempo até a falha foi de 0,69. Com isso, foi possível afirmar que a bomba está em fase de mortalidade infantil. Pelo referencial teórico da RCM, a estratégia de manutenção indicada é a corretiva. Esta estratégia visa eliminar os defeitos de projeto do equipamento, reforçar os itens que quebraram e remover as causas de origem das falhas.Associação Brasileira de Engenharia de Produção2013-06-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfaudio/mpeghttps://www.producaoonline.org.br/rpo/article/view/134110.14488/1676-1901.v13i2.1341Revista Produção Online; Vol. 13 No. 2 (2013); 759-783Revista Produção Online; v. 13 n. 2 (2013); 759-7831676-1901reponame:Revista Produção Onlineinstname:Associação Brasileira de Engenharia de Produção (ABEPRO)instacron:ABEPROporhttps://www.producaoonline.org.br/rpo/article/view/1341/1032https://www.producaoonline.org.br/rpo/article/view/1341/1033Copyright (c) 2014 Revista Produção Onlineinfo:eu-repo/semantics/openAccessMengue, Denis CarlosSellitto, Miguel Afonso2015-11-11T17:25:44Zoai:ojs.emnuvens.com.br:article/1341Revistahttp://producaoonline.org.br/rpoPUBhttps://www.producaoonline.org.br/rpo/oai||producaoonline@gmail.com1676-19011676-1901opendoar:2015-11-11T17:25:44Revista Produção Online - Associação Brasileira de Engenharia de Produção (ABEPRO)false |
