Resumo
A busca pelo melhor desempenho na manutenção exige dos gestores que eles acompanhem de perto o processo interno da empresa, pois as abordagens com valores atuais demonstram que a manutenção tem surpreendido a todos com a sua busca pela melhoria contínua. O presente trabalho apresenta dados obtidos após uma pesquisa de campo realizada dentro de uma empresa de manutenção de componentes hidráulicos, onde é possível observar uma redução nos custos de manutenções em bombas hidráulicas em uma empresa que opera em ambiente marítimo, em seguida a implementação da manutenção baseada em condição. Para a elaboração do trabalho foram utilizados, além das informações constantes da revisão da literatura, os dados obtidos por meio do estudo do caso analisado. Na empresa estudada, era comum o uso da Manutenção Corretiva para conserto dos equipamentos defeituosos. O método utilizado pela empresa nos anos de 2018 a 2021 se tornara bastante custoso e desvantajoso, visto que o processo de manutenção fazia com que todo o ciclo envolvido parasse. Para manutenir a Bomba Hidráulica, era necessário que a mesma não funcionasse para fazer-se a correção necessária. No ano de 2022, foi utilizada a Manutenção Baseada na Condição, ou CBM (Condition Based Management), onde houve uma grande vantagem na utilização. O estudo de caso realizado demonstra que o período utilizado para a CBM fora menos custoso e utilizou-se menos recursos e tempo. Alguns dos métodos utilizados para identificação do problema anterior à falha são: Termografia e Análise de Vibrações. Os métodos serão desenvolvidos em tópicos específicos para complemento do estudo de caso. Por fim, a conclusão que será desenvolvida é uma redução de 51% nos custos com manutenção sobre a empresa, diminuição do tempo aplicado e redução na quantidade de equipamentos manutenidos, graças à utilização da CBM. Deve-se lembrar que os equipamentos, métodos e abordagens descritas estão em constante evolução, visando a melhoria contínua para obter-se os melhores resultados possíveis.
The search for better performance in maintenance requires managers to closely monitor the company's internal process, as approaches with current values show that maintenance has surprised everyone with its quest for continuous improvement. The present work presents data obtained after a field research carried out within a hydraulic components maintenance company, where it is possible to observe a reduction in the maintenance costs in hydraulic pumps in a company that operates in a maritime environment, after the implementation of the maintenance condition based. For the preparation of the work, in addition to the information contained in the literature review, data obtained through the study of the analyzed case were used. In the studied company, it was common to use Corrective Maintenance to repair defective equipment. The method used by the company in the years 2018 to 2021 had become quite costly and disadvantageous, as the maintenance process caused the entire cycle involved to stop. To maintain the Hydraulic Pump, it was necessary that it did not work in order to make the necessary correction. In the year 2022, Condition Based Maintenance, or CBM (Condition Based Management), was used, where there was a great advantage in its use. The case study carried out demonstrates that the period used for the CBM was less costly and less resources and time were used. Some of the methods used to identify the problem prior to the failure are: Thermography and Vibration Analysis. The methods will be developed in specific topics to complement the case study. Finally, the conclusion that will be developed is a 51% reduction in maintenance costs for the company, a decrease in the time spent and a reduction in the amount of equipment maintained, thanks to the use of CBM. It should be remembered that the equipment, methods and approaches described are in constant evolution, aiming at continuous improvement to obtain the best possible results.
