Evaluación funcional y reparación de la trituradora-extrusora de la facultad de arquitectura e ingeniería

Abstract

The research was developed due to the operational limitations of the crusher-extruder machine of the Faculty of Architecture and Engineering, caused by failures in the electrical, mechanical and thermal systems, which prevented a continuous process, affecting the quality of the material obtained and restricting its academic use, the objective was to repair the machine through a functional evaluation of its systems and restore its operability, the methodology was a quantitative approach. The electrical and mechanical systems were reviewed and corrected through technical inspection and followed by corrective and preventive maintenance to guarantee its operation, while the experimental design was applied only to the thermal system, evaluating the behavior of the resistances and the temperature control through thermocouples, regression analysis and standard deviation. PET, HDPE and PLA plastics were used for performance tests, allowing verification of thermal stability, operational continuity and process efficiency based on the ratio of initial to final mass. The results showed efficiencies above 90% when the material was previously cut, as well as stability in the thermal ranges defined for the operation of the equipment. It was concluded that the intervention carried out allowed the return of functionality to the shredder-extruder machine and established clear technical conditions for its academic and research use, ensuring a more stable, controlled and reliable process and possible applications in the automotive industry.
