Gene Vogel EASA Pump & Vibration Specialist
Una de las reparaciones más comunes en las bombas centrífugas consiste en reemplazar los anillos de desgaste deteriorados o dañados. En las bombas con impulsores cerrados (con una cubierta frontal como se describe más adelante), habrá un anillo de desgaste en la carcasa y posiblemente un anillo de desgaste en el impulsor, que se ajusta al diámetro exterior (OD) del ojo de succión. Los impulsores también pueden tener anillos de desgaste traseros que son importantes para controlar el empuje axial. Las bombas con impulsores abiertos generalmente no tienen problemas con la tolerancia del anillo de desgaste del ojo de succión, pero a menudo tienen anillos de desgaste traseros. Las holguras entre el anillo de desgaste de la carcasa estacionaria y el anillo de desgaste del impulsor rotativo son fundamentales para un adecuado funcionamiento de la bomba. Aunque muchos fabricantes de bombas proporcionan tolerancias y dimensiones correctas, otro no lo hacen; en la actualidad existen una gran cantidad de bombas de fabricantes antiguos que ya han desaparecido, donde los datos de las dimensiones simplemente no están disponibles.
