Abstract

UNA BOMBA CENTRIFUGA DE ETAPAS MULTIPLES PARA AUMENTAR LA PRESION DE UN FLUIDO DE TRABAJO QUE PASA A SU TRAVES. LA BOMBA INCLUYE UNA CARCASA (12), UN EJE DE ROTOR (18) MONTADO DE FORMA QUE ROTE DENTRO DE LA CARCASA (12) Y UNA PLURALIDAD DE ROTORES (28) MONTADOS ESPALDA CON ESPALDA SOBRE EL EJE DE ROTOR. HAY UN COJINETE MAGNETICO RADIAL CON UNA CUBIERTA (26) MONTADO ALREDEDOR DEL EXTREMO SALIENTE (22) DEL EJE DE ROTOR (18) Y HAY MONTADOS UN COJINETE DE EMPUJE MAGNETICO (44) Y UN COJINETE RADIAL MAGNETICO (24) ALREDEDOR DEL EXTREMO ACCIONADOR (20) DEL EJE DE ROTOR. LA BOMBA NO TIENE NINGUN CONDUCTO DE RETORNO DEL FLUIDO DE TRABAJO QUE CONECTE LAS CAMARAS DEL FLUIDO DE TRABAJO A LOS EXTREMOS ACCIONADORES Y SALIENTES DEL EJE.
