Abstract

LA INVENCION SE REFIERE A UN SISTEMA DE ACCIONAMIENTO HIDRAULICO PARA UNA PRENSA. EL SISTEMA DE ACCIONAMIENTO ESTA DISEÑADO COMO UN SISTEMA REGULADO DE FORMA SECUNDARIA EN DONDE SE DISPONE DE UN TRANSFORMADOR (6,7) HIDRAULICO, QUE CONSISTE EN DOS MAQUINAS (6,7) HIDROSTATICAS ACOPLADAS MECANICAMENTE, CADA UNA DE ELLAS CON VOLUMENES DE ENTRADA Y DE SUMINISTRO AJUSTABLES. LA PRIMERA MAQUINA (6) ESTA CONECTADA A UN SISTEMA (3,4) DE PRESION CON UNA PRESION CONSTANTE O IMPUESTA Y LA SEGUNDA (7) ESTA CONECTADA AL CILINDRO (16) DE PRESION. DE ACUERDO CON LA INVENCION EL SISTEMA DE ACCIONAMIENTO ESTA DISEÑADO DE TAL FORMA QUE LA PRESION PREVIA SOBRE EL CILINDRO (16) DE PRESION Y EL PROCESO EN MOVIMIENTO RAPIDO Y EL DESPLAZAMIENTO DE PRESION, ASI COMO LA DESCOMPRESION DEL CILINDRO DE PRESION Y EL ENJUAGUE DE MEDIOS DE TRABAJO CALIENTES EN EL CIRCUITO CERRADO TIENE LUGAR SIN PERDIDAS DE ESTRANGULACION O LA POTENCIA ES RECUPERADA POR MEDIO DEL TRANSFORMADOR HIDRAULICO.
