Abstract

EN UNA BOMBA VOLUMETRICA ROTATIVA CON GEROTOR UN PRIMER DIAMETRO EXTERIOR D1 DE LA CORONA EXTERIOR (23), SOBRE UNA PARTE (31) DE LA ALTURA, SE REDUCE HASTA EL VALOR DEL DIAMETRO TEORICO EN FONDO DE DENTADO, ESTANDO LOS DIENTES (29) DE LA CORONA (23) CONECTADOS Y LLEVADOS POR UN ANILLO CONTINUO (33), DE MANERA QUE ASEGURE UNA ALIMENTACION RADIAL DE LA BOMBA A TRAVES DE LOS ESPACIOS (30) DISPUESTOS ENTRE LOS DIENTES (29) DE LA CORONA (23). SE PUEDE ADJUNTAR UNA DISPOSICION DE PERFIL DISIMETRICO DE LOS DENTADOS.
