Abstract

BOMBA DE ENGRANAJES. FORMADA CON UNA CARCASA (1), QUE ALOJA UNA RUEDA INTERIOR (3), DE DENTADURA EXTERIOR, Y UNA RUEDA HUECA (4), CON DENTADURA INTERIOR, QUE ENGRANAN ENTRE SI, TENIENDO LA PRIMERA UN DIENTE MENOS QUE LA SEGUNDA, Y UNA PLACA DE MANDO (7) Y TAPA (8) ATORNILLADAS A ELLA. LA ASPIRACION (13) SE REALIZA A TRAVES DE UNA ESTRANGULACION (9) EN LA ZONA (11), Y LAS CAMARAS QUE SE FORMAN ENTRE LOS DIENTES DESPLAZAN EL FLUIDO A LA ZONA DE SALIDA (15), A TRAVES DE UNOS ORIFICIOS (16) SITUADOS EN LA PLACA DE MANDOS (7), DOTADOS DE UNAS VALVULAS DE RETENCION CONSISTENTES EN UNAS LENGUETAS ELASTICAS, SITUADAS EN UNA BRIDA (20) DE FORMA SEMICIRCULAR, Y QUE TIENEN UN TOPE DE APERTURA.
