Determinación de pérdidas por fugas en tuberías de aire comprimido mediante la técnica de ultrasonido pasivo en el laboratorio de mantenimiento predictivo de la Facultad de Mecánica

Abstract

This investigation was accomplished to detect leaks on compressed air systems through of predictive passive ultrasound technique was achieved as well as quantify energy losses that exist in compressed air systems leaks. This research is focused on analyzing the consequences of leaks and its impact on the pressure and flow parameters that exist in compressed air systems are. For analysis a module is built that simulates a compressed air system in which leaks through holes with different diameters. In each leak was measured with equipment passive ultrasound decibels in the flowmeter was observed airflow that ran away for every point, for measuring the pressure lost in the system a pressure gauge and a pneumatic piston descends to hit down its rod to a digital balance this with the purpose of observing what was the force that marked us with every open drain piston. For quantifying the energy losses is used FLUKE 435 series II equipment, the electrical power obtained is consumed and wasted because each leak, then the analysis was performed to verify the economic loss which would because of leakage. This work was conducted under the research at ESPOCH-2012; ARTICLE V thus also, it´s recommended indirectly contribute to the new production and energy matrix.
