Abstract

UNA BOMBA DE FLUJO TOTALMENTE CIRCUNFERENCIAL QUE INCLUYE UN MOTOR QUE TIENE UN ESTATOR, UN EJE DISPUESTO DE FORMA ROTATIVA EN EL ESTATOR Y UN ROTOR MONTADO SOBRE EL EJE DE MODO QUE ROTE RESPECTO AL ESTATOR, UNA CUBIERTA DE BASTIDOR EXTERIOR (25) DISPUESTA ALREDEDOR DEL ESTATOR, UNA CARCASA DE LA BOMBA CILINDRICA EXTERIOR (5) DISPUESTA ALREDEDOR DE LA CUBIERTA DE BASTIDOR EXTERIOR CON UN ESPACIO ANULAR (40) FORMADO ENTRE MEDIAS Y UN CONJUNTO DE BOMBEO MONTADO EN UN EXTREMO DEL EJE PARA BOMBEAR UN FLUIDO DE MODO QUE ENTRE EN EL ESPACIO ANULAR (40). LA CARCASA DE LA BOMBA CILINDRICA EXTERIOR TIENE UNA VENTANA DE SUCCION (5A,5B) PARA LA INTRODUCCION DE UN FLUIDO A SU TRAVES. HAY UNA CAJA DE SUCCION (10) MONTADA SOBRE LA CARCASA DE LA BOMBA CILINDRICA EXTERIOR (5) PARA LA INTRODUCCION DE UN FLUIDO A SU TRAVES Y A TRAVES DE LA VENTANA DE SUCCION (5A,5B) EN EL CONJUNTO DE BOMBEO, EN DONDE LA CAJA DE SUCCION TIENE FORMADO EN ELLA UN ORIFICIO DE SUCCION.
