Abstract

EN UNA BOMBA DE HILADO PARA LA EXTRUSION FUNDIDA DE POLIAMIDAS SE DISPONE DE PERFORACIONES (10,10'') CON SECCION TRANSVERSAL PARTICULARMENTE CIRCULAR, FORMADAS EN LA PLACA (6) CENTRAL DE TAL MODO, QUE LA ZONA DE SECCION TRANSVERSAL DE LAS PERFORACIONES (10,10'') DISPONE DE FORMA CONICA HACIA LA PARTE POSTERIOR (6'''') DE LA PLACA (6) CENTRAL Y LOS CENTROS DE LAS PERFORACIONES (10,10'') DISPONEN DE UN CONTORNO PARABOLICO HACIA LA PARTE POSTERIOR (6'''') DE LA PLACA (6) CENTRAL. LAS PERFORACIONES (01,10'') DISEÑADAS DE ESTA MANERA HACEN POSIBLE LA PREVENCION DE DEPOSITOS DENTRO DE LOS CANALES DE BOMBEO E INCREMENTAN LA PRODUCTIVIDAD DE LA EXTRUSION DE FUSION DE ALTA CALIDAD POR ENCIMA DEL 10 %.
