Abstract

UN APARATO ESTA PREVISTO PARA LLENAR UN TUBO (20) CON FLUIDO Y PARA PRESURIZAR EL TUBO (20) PARA A EXPANDIR Y FORMARLO EN UNA MATRIZ (22) POR EJEMPLO. EL APARATO ESTA PROVISTO DE UN CIRCUITO DE FLUIDO DE GRAN CAUDAL A BAJA PRESION PARA LLENAR Y DRENAR RAPIDAMENTE EL TUBO, JUNTO CON UN CIRCUITO DE FLUIDO A GRAN PRESION DE POCO CAUDAL SEPARADO PARA PRESURIZAR Y DESPRESURIZAR EL TUBO (20) EL CIRCUITO DE ALTA PRESION DEL APARATO COMPRENDE UN ARBOL (19) QUE TIENE UN ORIFICIO LONGITUDINAL (4) QUE SE COMUNICA CON UNA FUENTE DE FLUIDO DE ALTA PRESION Y MEDIOS DE CONTROL MEDIOS DE OBTURACION DEL TUBO (7) ADYACENTES AL EXTREMO DELANTERO DEL ARBOL (1) PARA OBTURAR EL TUBO (20) CUANDO EL ARBOL (1) ESTA ACOPLADO CON EL TUBO (20) Y EL FLUIDO DE ALTA PRESION CORRE DENTRO DEL TUBO (20), Y MEDIOS ALTERNATIVOS DEL ARBOL (8) PARA HACER AVANZAR Y RECULAR EL ARBOL (1). EL CIRCUITO DE GRAN CAUDAL DEL APARATO COMPRENDE UNA ENVOLTURA ABIERTA POR LA PARTE DELANTERA (19) QUE ALOJA EL EXTREMO DELANTERO DEL ARBOL (1)CUANDO ESTA RETRAIDO Y QUE TIENE UNA ABERTURA TRASERA QUE SE ACOPLA DESLIZABLE Y OBTURABLEMENTE AL EXTREMO DELANTERO DEL ARBOL (1) TRASERO DEL ELEMENTO DE OBTURACION DEL TUBO (7), EL INTERIOR DE LA ENVOLTURA (19) SE COMUNICA CON UNA FUENTE DE FLUIDO DE BAJA PRESION DE GRAN CAUDAL Y MEDIOS DE CONTROL, MEDIOS DE OBTURACION EXTERNOS (24) ALREDEDOR DE LA ABERTURA DELANTERA DE LA ENVOLTURA (19) PARA OBTURAR UNA SUPERFICIE EXTERNA ADYACENTE DE UN EXTREMO DEL TUBO (20), Y MEDIOS ALTERNATIVOS DE LA ENVOLTURA PARA HACER AVANZAR Y RECULAR LA ENVOLTURA (19). EN FUNCIONAMIENTO, LA ENVOLTURA (19) AVANZA PARA OBTURAR LA SUPERFICIE EXTERNA (23), EL TUBO (20) SE LLENA CON EL FLUIDO DE BAJA PRESION, EL ARBOL (1) ES PRESURIZADO, Y EL PROCESO SE INVIERTE PARA LIBERAR EL TUBO (20).
