Metodología de remanufactura de ventiladores centrífugos industriales de mediana presión integrando ingeniería inversa

Abstract

Centrifugal fans are fundamental elements in ventilation systems and industrial processes, whose continuous wear requires maintenance and restoration strategies. In this context, remanufacturing is considered a key process within the circular economy, as it extends the equipment's useful life, reduces resource consumption, and reduces environmental impact. The objective of this work is to design a systematic methodology for the remanufacturing of centrifugal fans through the application of reverse engineering, geometric inspection protocols, and surface finish alternatives, ensuring that the recovered products meet operational and quality standards. The proposed methodology was applied in a case study, incorporating a literature review, comparative analysis of flowlines using CFD, and defect inspection using specialized software. These results allowed for a correlation between fluid behavior and the physical deterioration of the equipment, identifying critical wear zones on the blades, associated with flow recirculation and coating loss. Finally, the methodology allowed for the recovery of components such as the volute, motor, and impeller, documenting the process and demonstrating its replicability, reducing manufacturing costs compared to new parts and contributing to industrial sustainability.
