Abstract

SE PRESENTA UN SISTEMA DE APOYO EN UNA REFINADORA PARA FABRICAR PULPA, EN DONDE EL MATERIAL EN BRUTO SE REFINA EN UN HUECO DE REFINAMIENTO ENTRE AL MENOS UN PAR DE MIEMBROS REFINADORES (22, 24) QUE GIRAN UNO CON RELACION AL OTRO, EN DONDE AL MENOS UNO DE DICHOS MIEMBROS REFINADORES (24) ESTA SOPORTADO POR UN EJE GIRATORIO Y AXIALMENTE MOVIL (26). EL SISTEMA DE APOYO COMPRENDE UN DISPOSITIVO DE APOYO AXIAL HIDROSTATICO/HIDRODINAMICO COMBINADO Y CONSTA DE UN ALOJAMIENTO CILINDRICO (32) CON AL MENOS UN PISTON CILINDRICO GIRATORIO (30), QUE ESTA MONTADO SOBRE EL EJE GIRATORIO (26) PARA GIRAR CON EL MISMO. AL MENOS UN CILINDRO ANULAR EXTERIOR Y AL MENOS UN CILINDRO ANULAR INTERIOR CONCENTRICO (200, 202 Y, RESPECTIVAMENTE, 210, 212) ESTAN DISPUESTOS PARA APRETARSE CONTRA UNA DE LAS SUPERFICIES EXTREMAS DEL PISTON GIRATORIO (30), DE MANERA QUE SE FORME UN HUECO ESTANCO. LOS CILINDROS ANULARES INTERIOR Y EXTERIOR SON AXIALMENTE MOVILES PERO NO SON GIRATORIOS Y SE ENCUENTRAN SOPORTADOS POR UN PISTONANULAR ESTACIONARIO (29 Y, RESPECTIVAMENTE 33) SITUADO ENTRE DICHOS CILINDROS ANULARES, Y EL AREA DE LA CAVIDAD (213, Y RESPECTIVAMENTE, 214) FORMADA ENTRE EL CILINDRO ANULAR INTERIOR Y EL CILINDRO ANULAR EXTERIOR ES MAYOR HACIA EL PISTON ANULAR (29, Y RESPECTIVAMENTE, 33) QUE HACIA LA SUPERFICIE DEL EXTREMO DEL PISTON GIRATORIO. SE SUMINISTRAN UNOS CANALES (246, Y RESPECTIVAMENTE, 248) PARA SUMINISTRAR A DICHA CAVIDAD UN MEDIO DE PRESION HIDRAULICO.
