Abstract

SE PRESENTA UNA BOMBA MULTIETAPA DEL TIPO DE LAS QUE INCLUYEN UNA CAMISA (1), UN EJE (2) QUE ES COAXIAL CON LA CAMISA Y QUE ESTA CONECTADO A UN MOTOR ELECTRICO, Y ETAPAS ACTIVAS DE BOMBEADO RIGIDAMENTE ACOPLADAS AL EJE, CADA ETAPA ESTA FORMADA POR UNA HELICE (5) CON UN ANILLO FRONTAL Y MEDIANTE UN ELEMENTO DE DISTRIBUCION (6) QUE MIRA HACIA EL ANILLO CON LA INTERPOSICION DE ELEMENTOS DE SOPORTE ANULARES (7) CONFORMADOS COMO UN TAZON INVERTIDO; LAS HELICES DE HUECOS RADIALES Y SUS ELEMENTOS DE DISTRIBUCION ESTAN RIGIDAMENTE ACOPLADOS A LA CAMISA HECHA DE UN MATERIAL ALTAMENTE RESISTENTE AL DESGASTE, Y LAS HELICES ESTAN MONTADAS SOBRE EL EJE Y PUEDEN MOVERSE AXIALMENTE O FLOTAR CON UNA CARRERA PREESTABLECIDA CON RESPECTO AL ELEMENTO EN FORMA DE TAZON ASOCIADO, MIENTRAS QUE AL MENOS UN SOPORTE ANULAR Y UN ELEMENTO DE SELLAMIENTO (8) PARA LA HELICE SE INTERPONE ENTRE EL ANILLO FRONTAL DE CADA HELICE Y EL ELEMENTO ASOCIADO EN FORMA DE TAZON ESTA HECHO DE UN MATERIAL QUE ES MAS RESISTENTE AL DESGASTE QUE LAS HELICES Y ES ADECUADO PARA AGUANTAR EL EMPUJE AXIAL DE LAS DIFERENTES ETAPAS Y PARA EVITAR QUE CUALQUIER FLUIDO PUEDA ESCAPAR DURANTE EL FUNCIONAMIENTO DE LA BOMBA.
