Abstract

UNA BOMBA CENTRIFUGA PARA BOMBEAR SUSPENSIONES DE FIBRAS QUE INCLUYE UN ALOJAMIENTO DE BOMBA CENTRIFUGA (50) QUE DEFINE UNA CAMARA (54) PROVISTA DE UNA ENTRADA Y SALIDA DE LAS SUSPENSIONES. SITUADA ENTRE LA CAMARA DE BOMBEO SE ENCUENTRA UN IMPULSOR CENTRIFUGO (60). UNA CAMARA DE BOMBA DE VACIO (76) DEFINIDA POR UNA PARED FRONTAL (112) FRENTE AL IMPULSOR Y A LA PARED TRASERA (110) Y OPUESTA A LA PARED FRONTAL ESTA SITUADA ADYACENTE A LA CAMARA DE BOMBEO CENTRIFUGA (54). UN ROTOR DE LA BOMBA DE VACIO (96) ESTA MONTADO ENTRE LA CAMARA DE LA BOMBA DE VACIO A LA MISMA DISTANCIA DE LAS PAREDES FRONTAL Y POSTERIOR (112, 110). LA DISTANCIA AXIAL ENTRE EL ROTOR DE LA BOMBA DE VACIO Y LAS PAREDES FRONTAL Y POSTERIOR (112, 110), SE AJUSTA A UN VALOR MENOR DE 0.30 MM, Y PREFERIBLEMENTE, MENOR DE ALREDEDOR DE 0.20 MM.
