Abstract

SISTEMA DE PROTECCION CONTRA CARGA AXIAL DEL ARBOL DE UNA TURBINA DE VAPOR PROVISTA DE UNA PLURALIDAD DE CAMARAS, CADA UNA DEFINIENDO UNA ZONA DE PRESION QUE CONTIENE UN FLUIDO QUE, DURANTE EL FUNCIONAMIENTO DE LA TURBINA, SE ENCUENTRA A UNA PRESION QUE GENERA UNA CARGA DE EMPUJE AXIAL SOBRE EL ARBOL, DE TAL MANERA QUE, POR LO MENOS DURANTE LAS PARADAS RAPIDAS, PUEDE DESARROLLARSE ENTRE DOS DE LAS CAMARAS UNA DIFERENCIA DE PRESION CAPAZ DE GENERAR UNA EXCESIVA CARGA DE EMPUJE AXIAL SOBRE EL ARBOL, SE DISPONEN VALVULAS CONTROLABLES (30-36) CONECTADAS EN UNA VIA DE PASO DE FLUIDO ENTRE LAS DOS CAMARAS, Y ASIMISMO COMPONENTES DE ACCIONAMIENTO DE VALVULA (40-46, 60) PARA ACCIONAR LAS VALVULAS DURANTE LAS PARADAS RAPIDAS DE LA TURBINA CON VISTAS A REDUCIR LA DIFERENCIA DE PRESION ENTRE LAS DOS CAMARAS.
