Abstract

SOPORTE PARA LOS COMPONENTES DE ACCIONAMIENTOS REGULADORES ELECTRO-HIDRAULICOS PARA VALVULAS DE TURBINA, ESPECIALMENTE VALVULAS DE REGULACION, DE CIERRE RAPIDO Y DE DESVIACION DE TURBINAS DE VAPOR. EL CONVERTIDOR ELECTRO-HIDRAULICO, EL CILINDRO DE ACCIONAMIENTO HIDRAULICO Y EL SISTEMA DE ALIMENTACION HIDRAULICO ESTAN SUJETOS A LA CONSTRUCCION SOPORTE DISPUESTA EN LA CARCASA DE LA VALVULA, LA CUAL COMPRENDE DOS PLACAS (201, 202) PARALELAS ENTRE SI Y OTRA FRONTAL (203) QUE RODEAN AL RESORTE ACUMULADOR DE FUERZA (217). LOS DIVERSOS ELEMENTOS HIDRAULICOS COMPONENTES DEL ACCIONAMIENTO REGULADOR SUJETOS A LAS PLACAS DEL SOPORTE ESTAN CONECTADAS ENTRE SI A TRAVES DE CANALES (232, 236, 239...) MECANIZADOS EN LAS PLACAS.
