Abstract

UNA BOMBA CENTRIFUGA MULTIETAPAS PROVISTA DE UNA PLURALIDAD DE CARCASAS ENTREETAPAS CONECTADAS EN SERIE DE LAMINAS DE ACERO PRENSADAS QUE ALOJAN A LOS IMPULSORES RESPECTIVOS. CADA UNA DE LAS CARCASAS INCLUYE UNA PARED LATERAL CILINDRICA CENTRAL, UNA PARED INFERIOR, UNA PRIMERA PARED CILINDRICA QUE SE EXTIENDE INTEGRAMENTE DESDE UN EXTREMO DE LA PARED LATERAL CILINDRICA CENTRAL Y UNIDA A LA PARED INFERIOR, LA PRIMERA PARED CILINDRICA SIRVE COMO EL MIEMBRO MACHO DE UNA JUNTA DE ENCHUFE, Y DE UNA SEGUNDA PARED CILINDRICA QUE SE EXTIENDE INTEGRAMENTE DESDE EL EXTREMO OPUESTO A LA PARED LATERAL CILINDRICA CENTRAL Y PROVISTA DE UNA BRIDA QUE DEFINE UNA ABIERTA EXTREMA, AL SEGUNDA PARED CILINDRICA SIRVE COMO EL MIEMBRO FEMENINO DE LA JUNTA DE ENCHUFE. LA PARED LATERAL CILINDRICA CENTRAL TIENE UN DIAMETRO EXTERNO MAYOR QUE LOS DIAMETROS EXTERNOS DE LA PRIMERA PARED CILINDRICA Y LA BRIDA. LA CARCASA ENTREETAPAS ESTA FORMADA POR ESTIRAMIENTO Y PROTUBERANCIAS, PERO NO MECANIZADA PARA ALCANZAR LA PRECISION DIMENSIONAL DESEADA. POR LO TANTO, LA CARCASA ENTREETAPAS NO TIENE DEFORMACIONES NI ERRORES DIMENSIONALES QUE PODRIAN OCURRIR BAJO FUERZAS QUE PODRIAN DESARROLLARSE SI LA PARTE EN BLANCO SE SUJETARA PARA MECANIZARLA Y LAS FUERZAS Y EL CALOR QUE PODRIAN DESARROLLARSE SI SE MECANIZARA EL BLANCO.
