Abstract

UNA BOMBA CENTRIFUGA MULTIETAPAS CONECTADAS EN SERIE DE LAMINAS METALICAS PRENSADAS QUE ALOJAN A LOS RESPECTIVOS IMPULSORES. CADA UNA DE LAS CARCASAS INCLUYEN UNA PARED CILINDRICA LATERAL PARA ALOJAR EL IMPULSOR , UNA PARED INFERIOR UNIDA A LA PARED CILINDRICA LATERAL Y QUE SE EXTIENDE ALREDEDOR DE UNA ENTRADA PARA EL IMPULSOR, Y DE UNA PALA DE RETORNO ADOSADA A LA PARED INFERIOR REMOTAMENTE DEL IMPULSOR. LA PARED INFERIOR TIENE UNA REGION CENTRAL QUE SE PROYECTA DE FORMA CONICA O ESFERICA RADIALMENTE HACIA DENTRO Y HACIA EL IMPULSOR A UNA DISTANCIA QUE CORRESPONDE A LA EXTENSION DE DEFORMACION DE LA PARED INFERIOR BAJO LA DIFERENCIA DE PRESION ENTREETAPAS. LA DEFORMACION DE LA PARED INFERIOR QUE SE DESARROLLA BAJO LA PRESION GENERADA POR EL IMPULSOR NACE DEL CUERPO DE LA CARCASA SOLAMENTE, SIN AFECTAR A LOS PUNTOS DE SOLDADURA, QUE SE EVITA QUE SE ROMPAN DURANTE LAS PRESIONES QUE PODRIAN CONCENTRARSE SOBRE LOS PUNTOS DE SOLDADURA.
