Desarrollo de un plan de mantenimiento preventivo, para el área de producción de la empresa industrial RFR, en la ciudad Quito-Ecuador

Abstract

The following research work deals with the elaboration of a preventive maintenance plan for the company Industrial RFR, a metal-mechanic production company located in the province of Pichincha, in Quito - Ecuador. A list of the company's machines was made with the situational analysis of each machine. Using the technical revision of manuals, elaboration of codifications, technical data sheets, and work formats. Both criticality and failure modes and AFME effects were evaluated. Once the conditions of the machines were identified, a list of maintenance activities was created to execute them within the work plan. The intervention of machines through the list of activities is intended to improve productivity so that workers will act efficiently when performing repairs on the identified machines. Maintenance indicators were generated, where the OEE reveals a production performance of 51.40 %. Also, the Backlog indicator reflects a result of 29.94 % days between the current demand of the company with the number of workers and hours established in the company to finish pending production work. In order to help the company Industrial RFR, computer-aided maintenance management was implemented in order to collect the necessary information about the machines, as well as the maintenance work. This database is generated in the digital tool AppSheet, which allows to generation of new maintenance work dates and follow-up alerts to avoid deterioration of the machines. This helps to improve operational reliability when performing interventions on the machines.
