Plano de melhoria na gestão da manutenção em uma indústria de reciclagem de plástico

Abstract

This paper describes the LDPE (Low Density Polyethylene) recycling system of an industry located in Paraná, applying tools that aim to discover the criticality of its equipment. Subsequently, maintenance actions were developed for the equipment in which the failures presented a high degree of severity in relation to the others. To define the necessary actions that ensure greater reliability, availability, and safety of the equipment, the Reliability-Centered Maintenance (RCM) methodology was used. This methodology allows integration with other tools. In this study, Failure Mode and Effects Analysis (FMEA) was used, a tool used to indicate vulnerabilities in the system and subsequently perform an analysis focused on the element identified as the most critical in the system. The results found with the application of this tool helped to determine the priorities for actions, which are of utmost importance in classifying failures according to their criticality, enabling a more efficient selection of maintenance actions.
