Abstract
UNA BOMBA CON UN SISTEMA DE CORTE (3) SIRVE PARA IMPULSAR UN FLUIDO QUE LLEVE UNA CARGA DEBIDA A IMPUREZAS, MATERIAS GRUESAS Y SIMILARES, CON UN RODETE DE BOMBA (2) GIRATORIO QUE APOYA ROTATIVO EN UN CUERPO DE BOMBA (1) Y VA CONDUCIDO DE FORMA ESTANCA, QUE LLEVA UNA O VARIAS CUCHILLAS DE CORTE (4), ESTANDO LAS CUCHILLAS DE CORTE (4) Y EL RODETE DE LA BOMBA (2) ACCIONADOS CONJUNTAMENTE Y PRESENTANDO EL RODETE DE LA BOMBA (2) UNA ESTRUCTURA (8) CON SIMETRIA DE ROTACION HUECA QUE POR EL INTERIOR (2A) CONDUCE FLUJO DEL MEDIO Y HACIA EL EXTERIOR PENETRA EN EL MEDIO, EN EL CUAL O DENTRO DEL CUAL ESTAN SITUADAS LAS CUCHILLAS DE CORTE (4) QUE GIRAN AL MISMO TIEMPO. LA DISPOSICION, EL EFECTO Y EL MANTENIENDO DEL SISTEMA DE CORTE (3) SE PUEDEN MEJORAR POR CUANTO LAS CONTRACUCHILLAS (5) SITUADAS EN LA SUPERFICIE CONICA (6A) DE LA CARCASA DE CONTRACUCHILLAS (6) FIJA, ESTA FORMADA POR UNOS REBAJES (9) QUE TRANSCURREN RADIALMENTE SOBRE LA SUPERFICIE DEL CONO (6A), Y PORQUE LAS CUCHILLAS (4) ESTAN FORMADAS EN EL RODETE DE LA BOMBA (2) FORMANDO UN ANGULO (10) CON RESPECTO AL SENTIDO DE GIRO (11) Y CON UNA DISTANCIA RADIAL (12) QUE VA EN AUMENTO DESDE EL CENTRO (13) HACIA EL EXTERIOR, RETRASANDOSE EN EL SENTIDO DE GIRO (11).
