Elaboración de un plan de mantenimiento preventivo mediante la metodología del mantenimiento centrado en la confiabilidad para la Empresa Curtiduría Hidalgo de la ciudad de Ambato provincia de Tungurahua

Abstract

This technical project was carried out with the aim of developing a preventive maintenance plan using the maintenance methodology focused on reliability for the company Curtiduría Hidalgo of the city of Ambato. For this, as a first instance, the maintenance planning criteria were evaluated using the methodology proposed by Mariela Chang of her degree work. In the preparation of the maintenance plan, the hierarchical technical inventory was carried out based on the ISO 14224 Standard with its respective coding, a criticality analysis was carried out using the qualitative methodology in order to specify priorities for attention to the machines, and subsequently the technical sheets of each of them were raised. In the development of the RCM methodology, the functions, functional failures, failure modes, effects and their consequences were determined; by recording it in the information sheet and through the decision diagram, the maintenance activities were obtained with their respective frequency and the respective logistics for the execution. Finally, the technical staff of the company Curtiduría Hidalgo was trained in the management of the maintenance plan that was carried out in the Excel software. In the development of the preventive maintenance plan, 406 maintenance tasks were obtained, resulting in the total maintenance tasks, 175 maintenance tasks are conditioned, 145 tasks are cyclical reconditioning and 86 tasks are cyclical replacement, therefore, the tasks defined in the maintenance plan have the probability of reducing the occurrence of failure modes, therefore, the immediate application of the proposed plan is recommended, since this will result in an improvement in the results of reliability of the plant.
