Abstract

En este trabajo se presentó el diseño de un banco de ensayos para simular condiciones reales de cargas axial y radial en rodamientos 6005zz, a fin de obtener patrones de vibración que identifiquen los fallos ocurridos en los electro-ventiladores del sistema de refrigeración existente en el emplazamiento de generación distribuida con motores Hyundai (2,5 MW). Para el análisis de las vibraciones y caracterización de los fallos se empleó el método de impulso de choque y se consideró la velocidad angular, temperatura de los rodamientos y tiempo de explotación bajo condiciones reales. Los resultados obtenidos mostraron que los rodamientos utilizados no son adecuados para este tipo de electro-ventilador dada su carga axial. A fin de extender el tiempo de vida útil de los electro-ventiladores y mantener una extracción de calor constante en los motores, se recomendó sustituir los rodamientos 6005zz por rodamientos de rodillos cónicos 32005x.

Palabras claves: electro-ventiladores, rodamientos, vibraciones, diagnóstico, motores Hyundai.

Abstract

In this work is proposed a mechanical testing bench to simulate real conditions of axial and radial load in 6005zz bearings. The designed device is used to obtain the fault vibration patterns for the cooling system's electro-fans on the distributed generation substations with Hyundai motors (2,5 MW). Angular velocity, bearing temperature and operating time were considered critical variables in this study. Shock pulse method was used as vibration analysis method. The obtained results shown that the 6005zz bearings are not suitable due to the axial load of the electro-fan. In order to extend useful time of the electro-fans, the use of 32005x bearings was recommended.
Key words: electro-fans, bearings, vibrations, diagnosis, Hyundai motors
