Creating a maintenance plan is important in this company since it will allow specific control of the condition of the Jenbacher J320 engines to comply with the operating times that this machine must perform. Likewise, this will help reduce expenses when it comes to carrying out preventive maintenance on equipment. Caused by bad practices carried out in this type of procedures. Finally, this project will be developed in three phases with the purpose of complying with the construction of the maintenance plan that will allow traceability of the operation of each engine and control of the life cycle of the machine that will allow optimal operation of the engine. .Ítem Coeficiente de absorción de sonido en las llantas recicladas para cuartos de sonidoGomez Meza, Edwin Alberto; Alferez, Luis ErnestoIn the present work, you will find the study to a tire, study that analyzes the behavior of the tire facing sound, specifically the capacity of absorption and reflection of sound called "sound absorption coefficient". In order to find the absorption coefficient, it was used as a basis the norm UNE-EN ISO 10534-2, this standard contains methods for finding the value of absorption in a material. The method used to find the absorption coefficient of the tire was the acoustic impedance, which runs by the emission and reception of sound in a tube that is manufactured in aluminum and preferable, although other materials may be used such as PVC.Ítem Diseño y desarrollo de un plan de mantenimiento autónomo en la empresa ecoicoporesBeltrán Gamba, Eduard Alonso; Martínez Morales, Jorge Andrés; González, MauricioBy implementing the maintenance plan, the operators will be able to avoid possible machine failures to a large extent and, in the event that they occur, they will be able to overcome the failure quickly, improving the time to correct it and start up the machine. Implementing an autonomous maintenance system will greatly reduce the maintenance workload on a single collaborator and will, in turn, allow them to carry out different tasks of their own, in less time. The implementation of TPM in companies tends to be complicated by various human and resource parameters. The nature of the company according to its production line, allows the TPM mechanism to become an initial guideline that allows generating lower production costs and an improved TAK TIME. The company ECOICOPORES offers some particular characteristics for this. The productive process applied in the company, together with the maintenance carried out (attention to catastrophic failures), makes it necessary to implement a new integrated maintenance system, and the opportunity to build a TPM mechanism adapted to the particularities of the organization.Ítem Diseño e implementación de una pinza automatizada para la apertura de recipientes contenedores en La Celda Has 200Suarez Gaona, Andres Felipe; Forero Casallas, John AlejandroThe current document presents the phases of research, design, construction and development of a computerized clip that allows the uncovered containers containers in cell manufacturing HAS 200 of the Universidad Distrital Francisco José de Caldas located in the facilities of the technological faculty, through an industrialized that it allows manipulation and standardized system of this process.Ítem Realizar un análisis micro estructural del acero Aisi/Sae 1045 sometido a transformación inducida por plasticidad (TRIP)Castro Gomez, Efrain; Castañeda Rodriguez, Anderson Steven; Bohórquez Ávila, Carlos ArturoThe objective of this study is to develop a microstructural analysis of AISI / SAE 1045 steel subjected to conventional transformation induced by plasticity.

The experiments are carried out, thanks to mount an annex section of pipe of circular section, 3m in length, the Bancada Studies Fluid MF3 / 09 (PP30) of LETeF Laboratory, which was also adapted equipment PIV . The latter, composed mainly of a pulsed Nd-YAG laser and a high-speed camera CCD type, which are arranged to affect a display box acrylic on both sides to 90 °. These two devices allow identification of tracer particles in the circulating water, faithfully following the flow behavior evident. The fluid is characterized study. The study is limited to a range of Reynolds number, Re, up to 1800 for laminar flow, and 3000-40000 for turbulent flow. Velocity profiles are obtained for different values of Re in the center of the tube cross section. The captured images are then treated in Davis 8.2 software on your computer, using correlations. These data are compared with those calculated by theoretical formulas of fluid dynamics in pipes, for validation.Ítem Propuesta de implementación de gestión de activos bajo la norma ISO 55001 para plantas de tratamiento industrial y biológico (ptb y ptari) en planta colmotoresGarzón Barreto, Camilo Alberto; Sánchez Serrato, Juan Pablo; Alvarado Moreno, Alexander11 ABSTRACT This project aims to present a proposal for the implementation of an asset management system specifically for the industrial and biological water treatment plants owned by the company gm Colmotores.

The purpose of this research project is to propose and design an alternative for the energetic use of waste through an analysis of the most used technologies for this type of biomass with the objective of selecting the most adequate method for the University.Ítem Propuesta de aprovechamiento de los residuos sólidos urbanos para la generación de electricidad en el relleno sanitario de Doña JuanaAcuña Joya, Julio Alejandro; López Triana, Miguel Ángel; López Martínez, ArturoThe Doña Juana sanitary landfill located between the towns of Usme and Ciudad Bolívar, and which the Bogotá mayor's office designated as the place for the final disposal of urban solid waste in the city in 1988, today presents a considerable accumulation of waste. Alto receiving around 6,800 tons per day that are not little used. Throughout history, the landfill has seen three major accidents that have generated bad odors and quite high environmental damage, managing to affect the populations near the RSDJ, affecting the health and crops of the inhabitants. It is because of the above that the need arises to generate a sustainable proposal to avoid the supersaturation and expansion of the RSDJ, that is why the transformation of MSW into fuel for the generation of electric energy is proposed as an alternative, that is why the study of the Possible technologies that can provide a solution by converting waste into electrical energy, both for its operation and for offering as a service from the year 2022, reducing the tons of waste that enter the landfill. This energy would be generated through principles of utilization of MSW such as biodigestion or thermoelectric energy and through design obtain a solution from an electric power plant that can meet the needs of families near the landfill that do not have with an electricity service, seeking to minimize environmental risks and for Doña Juana to be able to amend the historical debt that according to (Mahecha Bustos, 2018) she has with the most vulnerable sectors in the southern sector of Bogotá.
