    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 pesada y vehículos livianos del GAD municipal del cantón Tiwintza de la provincia de Morona Santiago
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2023-08) Medina Barrera, Erick Santiago; López Velástegui, Jorge Enrique
    The Municipal GAD of the Tiwintza Canton is located in the Province of Morona Santiago, specifically in the city of Santiago de Tiwintza. This public institution has been providing service to its inhabitants for 20 years, the same one that is in charge of planning and managing state resources. through works for the benefit of their communities, thus encouraging trade, production and tourism. This technical project was carried out with the purpose of identifying the current state of the heavy machinery and light vehicles of the Municipal GAD of Tiwintza, through a preventive maintenance plan (PM), which contributes to improving availability and reducing, even avoiding breakdowns of the entire vehicle fleet. It was based on the NTP 679 guide and on a total productive maintenance (TPM) philosophy, since the public institution did not have a technical study of these characteristics. The assets were identified through technical sheets and their matrix of components with information collected in the institution's database, public procurement processes and vehicle license plates. On the other hand, the failure mode and effects analysis (AMFE) was also carried out with its respective criticality matrix, logs and maintenance ranges, through which the mechanical elements most likely to be replaced were determined with which it was sought to establish a Autonomous and planned maintenance without any setback. This preventive maintenance plan was designed to keep all road equipment in a safe, reliable and operational condition.

    Desarrollo de un plan de mantenimiento para la línea de producción de la empresa productora lácteos San José de la ciudad de Píllaro, basado en la metodología de mantenimiento productivo total (TPM)
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2023-01) Castro Pico, Jason Daniel; López Velástegui, Jorge Enrique
    Due to the need to improve production, this project allowed the development of a plan based on the methodology of Total Productive Maintenance TPM for the company Productos Lácteos San José in the city of Píllaro, information was collected which was provided by management and staff working in the company who collaborated in the collection of technical data of the machines involved in the research. In the development of the project, a diagnosis of the current situation of the company was elaborated, then for the consolidation and development of the Total Productive Maintenance TPM were made: technical data sheets of the equipment, environmental and safety suggestions for the operators, machine weighting tables, inventory of equipment and machines, interviews for the collection of information, as well as training through information campaigns detailing the model of the plan to be implemented in the company, In addition, Excel spreadsheets of Failure Mode Analysis "FMEA", Criticality Matrix, global effectiveness analysis and ending with the elaboration of the Maintenance Ranges, a statistic according to the need of each equipment and the application of the 5 "S" within the company taking into consideration the criteria described with the participation of the personnel of each area were elaborated.

    Desarrollo de un plan de mantenimiento preventivo para el área de inyección de la empresa Sistema de Asientos American de la ciudad de Ambato
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2021-08) Chicaiza Tipan, Cristian Israel; López Velástegui, Jorge Enrique
    The purpose of this technical project presented below is to achieve a preventive maintenance plan in the company named “SISTEMA DE ASIENTOS AMERICAN". The company mentioned above, in his injection area there are currently two injectors which require an early analysis, such as vertical and horizontal injectors IIP-001 and IIP-002 respectively. As a starting point, the most relevant information was collected. This is obtained through directive questions directed towards the workers because they manipulate the machines about 6 hours a day for the 6 days of work. It should be noted that the information obtained was not extensive, so an AMFE and Criticality matrix was created instead of starting with the statistical one. This allowed us to detail the most critical components of the injectors in addition to pre-established corrective activities. Through this, it was possible to organize the machine statistics detailing various times such as operation, repair, dead and stop times. All the aforementioned values allowed us to establish machine availability based on a constant failure rate. The last step was to carry out the technical work was the maintenance ranges in which preventive activities previously placed in the AMFE matrix will be put in place that allow maintaining the state of the machine, increasing the useful life of the machine and maintaining the economic profits of the company.
