Abstract

SISTEMA DE DIAGNOSIS PARA EVALUAR LA ACTUACION DE VALVULAS CRITICAS EN UN SISTEMA DE TURBINA DE VAPOR. EVALUA EL FUNCIONAMIENTO DE UNA VALVULA DE RETENCION (AR) EN UN CONDUCTO PARA EXTRAER VAPOR DE LA TURBINA. INCLUYE PRIMER SENSOR ACOPLADO AL EJE DE VALVULA, PARA PROPORCIONAR PRIMERAS SEÑALES REPRESENTATIVAS DE POSICION ANGULAR DEL EJE, Y UN SEGUNDO SENSOR ACOPLADO A LA VALVULA DE AISLAMIENTO PARA PROPORCIONAR SEGUNDAS SEÑALES REPRESENTANTIVAS DEL ESTADO DESEADO DE ESTA VALVULA DE AISLAMIENTO. UN ORDENADOR RECIBE LAS SEÑALES PRIMERA Y SEGUNDA, TENIENDO MEDIOS TEMPORIZADORES PARA DETERMINAR LA VELOCIDAD DE CAMBIO DE DICHA POSICION, AL RECIBIR LAS SEGUNDAS SEÑALES. EL ORDENADOR INCLUYE ADEMAS MEDIOS PARA COMPARAR LA POSICION DEL EJE RESPECTO A POSICIONES DE ESTE CORRESPONDIENTES A ESTADOS DE LAS SEGUNDAS SEÑALES, Y COMPARAR LA VELOCIDAD DEL CAMBIO, PARA IDENTIFICAR VARIACIONES RESPONDIENDO A CARACTERISTICAS DE VALVULA AR. EL ORDENADOR INFORMA DEL ESTADO DE OPERATIVIDAD DE VALVULA AR.
