Abstract

EN UN DISPOSITIVO DE CONTROL HIDRAULICO PARA UNA BOMBA DE FLUIDO VISCOSO CON AL MENOS UN CILINDRO DE ALIMENTACION (11) ACCIONABLE POR MEDIO DE UN CILINDRO HIDRAULICO (12), SU CAMARA DE ALIMENTACION (17) SE PUEDE CONECTAR POR MEDIO DE UNA VALVULA DE ENTRADA (18) QUE SE PUEDE ACCIONAR HIDRAULICAMENTE Y POR MEDIO DE UNA VALVULA DE SALIDA (2) QUE SE PUEDE ACCIONAR HIDRAULICAMENTE, DE MODO ALTERNATIVO A UN DEPOSITO DE RESERVA (19), ASI COMO A UNA LINEA DE ALIMENTACION (22), PARA LO CUAL EN LA FASE DE CARGA DEL CILINDRO DE ALIMENTACION (11) LA VALVULA DE ENTRADA (18) ESTA ABIERTA Y LA VALVULA DE SALIDA (21) CERRADA Y EN LA FASE DE ALIMENTACION DEL CILINDRO DE ALIMENTACION, EN LA CUAL SU PISTON ES ACCIONADO DE TAL MODO QUE REDUCE EL VOLUMEN EN LA CAMARA DE ALIMENTACION (17), LA VALVULA DE SALIDA ESTA ABIERTA Y LA VALVULA DE ENTRADA ESTA CERRADA, Y CON UN CONTROL HIDRAULICO DE SECUENCIA ACCIONA EL CAMBIO CORRECTO DEL CICLO ENTRE LAS VALVULAS DE ENTRADA Y DE SALIDA Y EL CAMBIO DEL ACCIONAMIENTO DE LA BOMBA, UNA VALVULA QUE FORMA PARTE DEL DISPOSITIVO DE CONTROL DE CAMBIO DEL CONTROL DE SECUENCIA Y DESCARGA DE LA PRESION EN LA CAMARA DE ALIMENTACION DEL CILINDRO DE CONTROL (53) DISEÑADA PARA ACCIONAR LA VALVULA DE SALIDA (21), TOMA LA FORMA DE UNA VALVULA (71) ACCIONADA ELECTRICA O HIDRAULICAMENTE, CONTROLADA DEPENDIENDO DE LA ELEVADA PRESION EN EL CILINDRO DE ACCIONAMIENTO (12) DEL CILINDRO DE ALIMENTACION (11). LA VALVULA (71) ES CONMUTADA A SU POSICION DE PASO CUANDO SE ALCANZA UN MINIMO AJUSTABLE Y PREDETERMINABLE DE LA PRESION EN EL CILINDRO DE ACCIONAMIENTO (12).
