Abstract

ACCIONAMIENTO REGULADOR ELECTRO-HIDRAULICO PARA VALVULAS DE TURBINA. EL ACCIONAMIENTO REGULADOR (1) ESTA MONTADO CON LA VALVULA DE TURBINA (3) Y SE COMPONE DE UN CONVERTIDOR ELECTRO-HIDRAULICO (10), UN CILINDRO DE ACCIONAMIENTO HIDRAULICO QUE COMPRENDE UNA BOMBA DE LIQUIDO (122) ALIMENTADA DESDE UN DEPOSITO DE LIQUIDO HIDRAULICO (120) Y ACCIONADO POR UN MOTOR ELECTRICO (121) Y UN ACUMULADOR DE PRESION HIDRAULICO (123), CONECTADO EN EL LADO DE PRESION A LA BOMBA DE LIQUIDO. EL CONVERTIDOR TRANSFORMA LAS SEÑALES ELECTRICAS GENERADAS POR UN REGULADOR DE TURBINA EN SEÑALES HIDRAULICAS. PARA ELLO UNA VALVULA (100) SE GOBIERNA POR UNA SEÑAL DE REGULACION ELECTRICA (RS) Y UNA VALVULA (101) SE GOBIERNA POR UNA SEÑAL ELECTRICA DE CIERRE RAPIDO.
