Abstract

BOMBA CENTRIFUGA DE CIRCULACION DE FLUIDO, CON ROTOR GUIADO AXIALMENTE MEDIANTE UN SOPORTE HIDRAULICO. EL DISPOSITIVO CONSISTE EN UN GORRON (51) DISPUESTO SOBRE LA PARTE AGUAS ARRIBA DE LA LLANTA (33) DEL ROTOR (3) Y DE UN COJINETE (52) DISPUESTO SOBRE LA PARTE DE ENLACE (44) DE LA LLANTA DE ESTATOR (43). EL CITADO COJINETE DISPONE DE UNA PLURALIDAD DE ALVEOLOS DE SUSTENTACION (53), UNIDOS POR UN COLECTOR INTERNO (55) Y EN COMUNICACION CON LA CAMARA DE SALIDA (2) MEDIANTE EL ORIFICIO (56). LA CIRCULACION DE FLUIDO A TRAVES DE LOS ALVEOLOS SE DEBE AL GRADIENTE DE PRESIONES EXISTENTE ENTRE EL CONDUCTO DE ENTRADA (1) Y LA CAMARA DE SALIDA (2). D
