Abstract

MONITOR DE LAS VIBRACIONES DE LOS ALABES DE UNA TURBINA PROVISTOS DE ANILLO PERIFERICO PROTECTOR Y OBJETIVO PARA EL MISMO. LOS ALABES SON CONDUCIDOS POR UN ROTOR (14) Y CONFIGURADOS EN UNA FILA (10). EL MONITOR INCLUYE UN SENSOR (24) ESTACIONARIO PARA INDUCIR CORRIENTES PARASITAS EN CADA SEGMENTO (18) DE ANILLO PERIFERICO PROTECTOR AL PASAR CADA SEGMENTO (18) POR EL SENSOR (24). EN CADA SEGMENTO (18) HAY SITUADO UN OBJETIVO (30) PARA PRODUCIR VARIACIONES EN LAS CORRIENTES PARASITAS INDUCIDAS. EL SENSOR (24) ES SENSIBLE A ESTAS CORRIENTES PARA PRODUCIR UNA SEÑAL DE SALIDA (VOUT) QUE CONTIENE INFORMACION CORRESPONDIENTE AL MOMENTO DE LLEGADA DEL OBJETIVO (30) AL SENSOR (24). SE HA DISPUESTO OTRO SENSOR (17) PARA PRODUCIR UN IMPULSO (19) UNA VEZ POR CADA REVOLUCION DEL ROTOR (14). UN MONITOR (42) DE VIGILANCIA DE VIBRACIONES DE ALABES ES SENSIBLE A LA SEÑAL DE SALIDA (VOUT) Y AL IMPULSO (19) UNA VEZ PORCADA REVOLUCION DEL ROTOR, PARA EXTRAER DE ELLOS INFORMACION RELATIVA A VIBRACIONES DE ALABES.
