Proposta de plano de manutenção centrada na confiabilidade de sistemas de AVAC monitorados pela IEM, SA

Abstract

In this work, the central problem is the reliability of the air conditioning system used intensively in the substations of the EDM, in the current context, the use of this equipment, on the one hand becomes indispensable due to the demands of comfort and safety of the workers, on the other hand, it represents an element for the image and profitability of the company IEM, SA. Due to the negative impact that possible performance problems represent, affecting relations with users, the perspective of Reliability Centered Maintenance was adopted to evaluate existing maintenance practices and indicate new procedures and changes in maintenance activities, based on surveys of field and technical discussions with maintenance staff and original equipment manufacturers. The work used typical quality management tools, such as FMEA and Pareto analysis, and was based on references in the literature on Maintenance Management to describe and systemically analyze the equipment in its functional context. Failure modes, the occurrence of failures and their consequences were investigated and the dynamic behavior of some components were analyzed. The FMEA methodology used is analyzed throughout the work and then applied to the air conditioning process, the results represent a deeper and more organized understanding of the equipment, a more complete and critical collective view of the work processes of the researched organization and the expectation of performance improvement of equipment and maintenance staff in the short term.
