Abstract

UN SISTEMA DE VIGILANCIA DE VIBRACIONES DE ALABES DE TURBINA ENVUELTOS COMPRENDE UNA PLURALIDAD DE SENSORES PARA PERCIBIR REPETIDAS VECES UN PERFIL DE UNA FILA DE ALABES DE TURBINA. UN MICROPROCESADOR COMPARA EL PERFIL PERCIBIDO CON UN PERFIL ESPERADO DE LA FILA DE ALABES DE TURBINA PARA DETECTAR EL MOVIMIENTO DE LOS ALABES DE TURBINA DEBIDO A LAS VIBRACIONES. EL MICROPROCESADOR GENERA ENTONCES UNA ALARMA DE OPERADOR Y DISPARA LA TURBINA EN RESPUESTA A LA DETECCION DE VIBRACIONES INACEPTABLES DE LOS ALABES DE TURBINA.
