Abstract

LA BOMBA DE SANGRE MUESTRA UNA RUEDA (13) IMPULSORA DISPUESTA EN UNA CARCASA (10) Y CONSISTIENDO EN UN DISCO (30) PLANO CON ALETAS (34) DISTANCIADAS UNA DE OTRA. LA RUEDA (13) DE IMPULSION ESTA MONTADA ENTRE BOLAS (18,20) QUE FORMAN UN COJINETE DE DESLIZAMIENTO AXIAL. LA PARED (35) FRONTAL Y LA PARED (14) POSTERIOR DE LA CARCASA DE LA BOMBA SON SUSTANCIALMENTE PARALELAS AL DISCO (30) DE LA RUEDA (14) DE IMPULSION. LA ALTURA DE LAS ALETAS (34) DECRECE LINEALMENTE EN TANTO EN CUANTO EL RADIO SE INCREMENTA, DE TAL MODO QUE EL ESPACIO ENTRE LA PARED FRONTAL (35) Y LAS PALETAS (34) SE INCREMENTA HACIA EL EXTERIOR. DADO QUE SE INCREMENTA TAMBIEN LA VELOCIDAD CIRCUNFERENCIAL, LA CUOTA DE CORTE DE CIZALLA PERMANECE CONSTANTE. UN ESPACIO DE ANCHURA CONSTANTE EN DONDE SE GENERA UN FLUJO SECUNDARIO ESTA PROVISTA ENTRE EL DISCO (30) DE LA RUEDA DE IMPULSION Y LA PARED (14) POSTERIOR PARA PREVENIR ZONAS DE AGUA MUERTAS.
