Abstract

LA INVENCION SE REFIERE A UN DISPOSITIVO DIFUSOR Y TRANSPORTADOR (1, 102, 202, 302) PARA UNA BOMBA DE IMPULSOR UNICO CENTRIFUGA DE AUTOCEBO, CON CANALES DE TRANSPORTE (15, 115, 215, 315) SITUADOS RADIALMENTE FUERA DEL DIFUSOR (13, 113, 213, 313) Y DENTRO DEL CUERPO DE LA BOMBA (3, 103, 203, 303) CON UN GROSOR COMPRENDIDO ENTRE LA CUBIERTA (7, 107, 207, 307) DEL CUERPO Y UNA PARED FRONTAL (6, 116, 216, 316) AL LADO DE LA PARED CIRCULAR (17, 117, 217, 317) DEL DIFUSOR, PERO NO FRONTALMENTE SUPERPUESTA A ESTE. EL DISPOSITIVO DIFUSOR Y TRANSPORTADOR (2, 102, 202, 302) DESVIA EL FLUJO DE LA DIRECCION PERIFERICA TANGENCIAL HACIA UNA DIRECCION CENTRIPETA QUE REDUCE LA ROTACION Y LA VELOCIDAD DEL FLUJO, PUEDE CONSTRUIRSE EN UNA SOLA PIEZA E INCLUYE ORIFICIOS FRONTALES (25, 125, 225, 325) PARA LA INSPECCION DE LAS PIEZAS INTERNAS DE LA BOMBA.
