Desarrollo de un plan de mantenimiento preventivo para las máquinas y equipos del laboratorio de investigación mecánica LIM-UTA

Abstract

The Mechanical Research Laboratory of the Technical University of Ambato LIM-UTA, is focused on the service of flammability testing of materials under the ISO 3795 standard [1]. It works under the ISO 17025 standard [2], which establishes the necessary requirements to work as a laboratory. Formed in 2019 with specialized technicians from the university, obtaining the recognition of the SAE and the designation of the MIPRO in 2021. Since its creation, only a scheduled maintenance plan has been drawn up, which does not cover the primary requirements that a preventive maintenance plan must meet [3]. In this project, a preventive maintenance plan was developed for the machines and equipment of the LIM-UTA mechanical research laboratory, based on the technical dossier according to the current documentation. The current state of the machines and equipment was established according to the Davis curve; its reliability was determined by applying the mathematical model of Weibull distribution according to NTP-331; failures and potential effects were identified by means of FMEA according to NTP-679. Finally, the plan was generated through the logs and ranges of activities, applying the criteria of the Total Productive Maintenance TPM program and delivering it to the UTA LIM for its respective approval and implementation. The elaboration of this technical project will allow LIM-UTA to develop its activities without any inconvenience or setbacks, which represent possible potential losses in legal and economic fields, both for LIM-UTA and for the Technical University of Ambato.
