Abstract
UNA BOMBA (2) CENTRIFUGA DE ETAPAS ABARCA UNA CARCASA 5 DE BOMBA, UN EJE 4 ROTOR, DOS RUEDAS 3 DE BOMBEO UNIDAS CON EL EJE 4 ROTOR, ASI COMO UN DISPOSITIVO 2A DE DESCARGA CON UNA CARCASA 6. EL EJE 4 ROTOR ESTA UNIDO CON UN DISPOSITIVO 1 MAGNETICO DE ACUERDO CON LA INVENCION DE TAL MODO, QUE SOBRE EL EJE 4 ROTOR EJERCE UNA FUERZA QUE ACTUA CONTRA LA FUERZA DE EMPUJE, PARA EVITAR UN CONTACTO DEL DISCO 8 DE DESCARGA EN EL CONTRADISCO 7 DE DESCARGA.
