Abstract(s)
As atividades da manutenção têm sido caracterizadas como um problema dentro das
empresas, desde há muitos anos. Contudo nos últimos anos, a manutenção tem sido vista de
outra maneira e tem sido reconhecida como uma parte fundamental e estratégica nas
empresas. Passando de ser um problema a uma atividade essencial ao ciclo de vida dos
equipamentos, e um meio de apoio à produção, que combina ações de gestão e técnicas com
a finalidade de obter elevada disponibilidade das equipamentos a baixos custos.
Esta mudança advém da globalização dos mercados, que deste modo fez com que as
organizações tenham que melhorar as suas prestações a todos os níveis para produzirem com
qualidade, a baixo custo e darem uma boa resposta ao consumidor final de forma satisfatória
face às suas necessidades.
Para além de aumentar a disponibilidade dos equipamentos, de manter a produção
estável e sem problemas, a manutenção é aplicada para garantir o bom funcionamento dos
equipamentos, tendo em vista a melhoria continua. Para se conseguir aplicar novas técnicas,
metodologias de apoio à manutenção é necessário o estudo dos acontecimentos ocorridos no
serviço da manutenção, recorrendo a dados do histórico da manutenção, de forma a averiguar
as causas das avarias, e daí estudar medidas e métodos de melhoria recorrendo a estudos que
tem em conta a vertente económica e técnica.
Desta forma neste trabalho, ao longo dos quatro capítulos, são abordados vários temas
sobre a gestão da manutenção, conceitos e definições de forma a analisar a forma de
operação de um equipamento destroçador de madeira com componente de transporte numa
indústria processadora de celulose.
O objetivo é avaliar os procedimentos de operação desse equipamento e as suas
consequências na disponibilidade e na manutenção do mesmo.
O caso vai ser tratado através do recurso a dados relativos ao histórico de manutenção,
pelo que também irão ser abordados os problemas associados à correta identificação das
ocorrências, à relação entre operação e manutenção e à qualidade das intervenções da
manutenção.
Com a análise dos dados identifica-se as avarias/falhas que ocorrem mais sendo estas:
Avaria mecânica, Avaria elétrica, Substituição de navalha e Encravamentos. De Janeiro a
Setembro verifica-se que existe baixa disponibilidade, nos restantes meses ocorrem avarias de
forma sistemática contribuindo também desta forma para a diminuição da produtividade. Para
fazer face deve-se de rever o plano de manutenção, e o planeamento de como se fazem as
intervenções da manutenção de forma a torna-los mais robustos e incrementar com novas
técnicas de gestão de manutenção. Realizar formações para todos os colaboradores e
incrementar novos métodos de recolha e registo dos dados que evidencie o histórico da
manutenção da melhor forma possível.
Maintenance activities have been characterized as a problem within companies for many years. However in recent years, maintenance has been viewed in a different way and has been recognized as a fundamental and strategic part in companies. From being a problem to an activity essential to the life cycle of equipment, and a means of production support, which combines management and technical actions to achieve high availability of equipment at low costs. This change comes from the globalization of markets, which has meant that organizations have to improve their performance at all levels in order to produce quality at low cost and to provide a good response to the end consumer satisfying their needs. In addition to increasing equipment availability, maintaining stable and trouble-free production, maintenance is applied to ensure the smooth operation of the equipment for continuous improvement. In order to be able to apply new techniques, maintenance support methodologies, it is necessary to study the events that occurred in the maintenance service, using data from the maintenance history, in order to find out the causes of the failures, and then study improvement measures and methods using studies which take account of the economic and technical aspects. Thus in this paper, over the four chapters, various topics on maintenance management, concepts and definitions are addressed in order to analyze the operation of a wood chipper equipment with transport component in a pulp processing industry. The objective is to evaluate the operating procedures of this equipment and its consequences on its availability and maintenance. The case will be addressed through the use of maintenance history data, so that problems associated with the correct identification of occurrences, the relationship between operation and maintenance, and the quality of maintenance interventions will be addressed. The data analysis identifies the most frequent faults / failures: mechanical failure, electrical failure, knife replacement and interlocks. From January to September, there is low availability in the remaining months. Systematic malfunctions occur, thus also contributing to the decrease in productivity. To cope with this, you need to review the maintenance plan, and plan how maintenance interventions are made to make them more robust and incremental with new maintenance management techniques. Conduct training for all employees and improve new data collection and recording methods that make the best possible maintenance history.
