Diseño e implementación de una red de aire comprimido para el taller de maquinaria pesada de la Carrera de Ingeniería Automotriz

Abstract

Nowadays, industrial processes utilize compressed air as a source of energy and motion conversion Similarly, compressed air can assist in the various pneumatic machines working, such as a pneumatic bench designed as a modular system enabling the construction and configuration of different pneumatic circuits. It allows for the execution of various tests and demonstrations. This project focused on implementing a compressed air network for the heavy machinery workshop to operate different devices available in a workshop for educational purposes. The methodology of the work corresponds to applied research using the principles of pneumatics, fluid mechanics, and thermodynamics for the design of the compressed air network. The approach includes an explanatory scope of the network design process using qualitative methods to determine the compressed air demand and necessary components through appropriate physical models. It ensures obtaining the dimensions and correct functioning in the heavy machinery workshop. The network components, such as the compressor, storage tank, pipe dimensions, and accessories, are established through this process. Functional tests demonstrate working pressures and flow rates by the specified requirements. The pressure drop is maintained at an acceptable value for the operation of the installed components. The installed network is designed as a closed circuit to ensure pressure balance. A 2 HP piston compressor with a maximum flow of 250 l/min and a maximum pressure of 800 kPa (8 bar) was used to operate the heavy machinery workshop equipment effectively.
