Abstract

BOMBA DE VACIO DE CANAL DE GAEDE QUE CONSTA DE UN ESTATOR (1) Y UNROTOR (2) ARRASTRADO EN ROTACION EN EL INTERIOR DEL ESTATOR, CONSTANDO EL ESTATOR UNA ENTRADA DE ASPIRACION (12) Y UNA SALIDA DE COMPRESION (13). SE CARACTERIZA PORQUE EL ROTOR, EN SU PARTE ACTIVA SITUADA ENTRE LA ASPIRACION Y LA COMPRESION, TIENE UNA FORMA HEMIESFERICA (9) Y ESTA SITUADO EN EL INTERIOR DE UNA CAVIDAD (10) IGUALMENTE HEMIESFERICA DEL ESTATOR, CONFUNDIENDOSE EL EJE DE DICHO ROTOR CON EL EJE DE LA CAVIDAD (10) IGUALMENTE HEMIESFERICA DEL ESTATOR, REALIZANDOSE LA ASPIRACION POR LA ZONA DEL GRAN CIRCULO DEL ROTOR HEMISFERICO, POR EL JUEGO RADIAL (JA) ENTRE EL ROTOR Y EL ESTATOR Y LA COMPRESION POR LA ZONA DEL VERTICE DEL ROTOR HEMISFERICO, POSICIONANDO UNA CUÑA REGULADORA AXIALMENTE EL ROTOR (2) EN RELACION AL ESTATOR (1), DE FORMA QUE DICHO JUEGO RADIAL A LA COMPRESION JR SE MAS DEBIL QUE EL JUEGO RADIAL A LA ASPIRACION JA.
