    Desarrollo de un plan de mantenimiento preventivo en base a la norma ISO 55000 para la maquinaria de la empresa Cepolfi en la ciudad de Ambato
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2024-02) Nuñez ChacaguasayV, Kevin Omar; López Velástegui, Jorge Enrique
    The increase in unexpected failures in the CEPOLFI company is detrimental to production due to unexpected stoppages and unplanned downtime. The lack of detailed historical records makes it difficult to identify failure patterns and predict optimal times to perform maintenance activities, resulting in significant costs from unforeseen repairs and constant replacement of components. A preventive maintenance plan is implemented that covers the collection of data in each of the areas, recording in an inventory all the machines and equipment found, coding them according to their respective area so that they can be identified more quickly. The preparation of technical sheets for each of the machines provides information about each machine. Likewise, analysis methods such as FMEA are implemented to identify each of the most critical failures of the machine, which helps make improvement decisions. The creation of matrices with the description of the possible failures that may occur with their respective criticality evaluation provides us with the necessary information for decision making. The range of machinery and the log template for data collection were also generated. more efficient.

    Desarrollo de un plan de mantenimiento preventivo para las máquinas, equipos y sistemas del taller de innovación y desarrollo tecnológico de la Facultad de Ingeniería Civil y Mecánica
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2024-02) Guato Caiza, Bryan Wilson; Robayo Fonseca, Geovanny Sebastián; Castro Miniguano, Christian Byron
    The lack of preventive maintenance on machines, equipment and systems shortens their useful life, for this reason in this technical project a preventive maintenance plan was developed for the machines of the FICM Innovation and Technological Development Workshop. In the development of the technical project, the coding of each of the machines was carried out in order to identify them quickly, the technical sheets, the general characteristics, the service conditions, the list of spare parts, the drawings, diagrams, the dimensions and tolerances, the assembly instructions, the operating instructions, etc. were also carried out. The analysis of the FMEA matrices was carried out with the help of the NTP 679 Standard, analyzing the most critical elements, which are more prone to suffer failures causing unexpected interruptions in the operation of the machines, the causes of failure, functional failures and failure effects were also analyzed. Then, the criticality matrices were carried out to identify and prioritize the most critical elements of each of the machines that need improvement. Finally, the preventive maintenance plan was developed under specialized software, in which the Logs and Maintenance Ranges of each of the machines are detailed, where it will be possible to visualize and print the technical sheets, the drawings and the monthly maintenance activities, it will also be possible to record the stop and repair times of each activity generating the curve of the bathtub.

    Desarrollo de un plan de mantenimiento preventivo, para la maquinaria del área de trituración de materiales pétreos en la empresa Jeal Construcciones
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2024-02) Freire Revelo, Andrea Paola; López Velástegui, Jorge Enrique
    The company does not currently have a preventive maintenance plan, so it uses a reactive approach, in which it waits for equipment to fail before proceeding to repair it. This not only generates interruptions in the company's production, but also increases the risk of occupational accidents, reduces the useful life of the equipment and generates periods of inoperability, since the machinery used in the process of crushing stone materials is important for the company's operation. This project was developed in several steps, the first one was to make an inventory of the machines belonging to the crushing area, then the critical equipment was identified and its current status was evaluated, also technical data sheets, FMEA and statistical matrices were made where the availability of the machines could be analyzed and the criticality and identification of components susceptible to failures were determined. Different ranges of maintenance were elaborated with activity guidelines with the objective of improving the performance and useful life of the machines and their components, knowing their reliability and availability; subsequently, preventive maintenance matrices were elaborated with different activities and the periodicity with which they were carried out throughout the year. Finally, fulfilling the objectives, the maintenance plan was uploaded to a specialized software, with the objective of automating maintenance tasks and improving the efficiency and productivity of its processes and personnel.

    Desarrollo de un plan de mantenimiento preventivo para las máquinas de control e inspección de calidad de la empresa Siccpetr S.A. de la ciudad del Coca
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2024-02) Castro Núñez, Joselo Alexander; Castro Miniguano, Christian Byron
    The company SICCPETR S.A. is located in the province of Francisco de Orellana, in the city of Coca, this company is dedicated to perform quality control processes with non-destructive testing in the oil sector, to make a technical visit in the company was found to lack a record of machines, inventories and maintenance plan that does not keep a detailed record of activities and this affects the production of the same, it was necessary to collect information from the machines and equipment it owns, performing preventive maintenance to verify that most common failures exist. In this technical project, a dossier of machines was prepared, which includes an inventory and technical data sheets, reflecting the most relevant and detailed information on the company's machines and equipment. Through statistical analysis, it was determined that most of the machines are in an optimal state of operation, also with the FMEA matrix, criticality matrix, logbook and range of maintenance, it was determined, which components are the most critical to failures and the most likely to be replaced, with this information was implemented a software where a record of more detailed activities of preventive maintenance, more organized and easy to use. On the other hand, as a result, the technical note NTP 679 was of fundamental use to carry out this technical project, which will help to avoid emergent stoppages of machines and equipment, to reduce repair times and to reduce costs.

    Desarrollo de un plan de mantenimiento preventivo para las máquinas y equipos del laboratorio de investigación mecánica LIM-UTA
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2024-02) Pozo Freire, Diego Alexander; Castro Miniguano, Christian Byron
    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.

    Desarrollo de un plan de mantenimiento preventivo para los equipos y maquinaria de la empresa Carrocerías Altamirano de la cuidad de Ambato
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2024-01) Cholota Chaglla, Jonathan Gonzalo; Paredes Robalino, María Belén
    The company Carrocerias Altamirano has allowed an exhaustive analysis of the equipment and machinery used in its manufacturing and repair operations with the problem that it does not currently have a preventive maintenance model specifically designed to ensure optimum performance and prolonged useful life of its essential assets. With this idea in mind, the present research work is proposed; with the purpose of approaching a methodology of a mixed nature, since it is based on both a qualitative and quantitative model. It is essential to highlight that the creation of a model aimed at identifying the parameters for the maintenance plan of the machinery of Carrocerias Altamirano required the use of a broad bibliographic base to specify each aspect related to preventive and corrective activities within the company. Additionally, the condition of the machines was evaluated by means of the prevention technical note NTP 679, and statistical data from previous years were used to detail the availability of the machines. Once these data were analyzed, they were incorporated into the FMEA matrix to determine the priority risk number NPR, and from that perspective to obtain an estimate of reliability and availability for the application of a CMMS model. It is noteworthy that the current evaluation of the condition of the machines at Carrocerías Altamirano indicates that the vast majority of them are in semi-optimal condition and show high performance of 78 percent. This is due to their origin, age and characteristics, which allow them to operate efficiently and contribute to the company's production process.
