Abstract

Se describe un compresor centrífugo de etapas múltiples (1); el compresor comprende una carcasa (3) y un vástago (9) sostenido de forma giratoria en dicha carcasa (3) por medio de al menos un primer cojinete y un segundo cojinete (11; 13); al menos un impulsor entre cojinetes (19A a 19D) está montado sobre el vástago (9), entre dicho primer cojinete y dicho segundo cojinete (11, 13); un impulsor voladizo (15) está montado en un extremo del vástago (9); una primera disposición de diafragma (25, 25X) se ubica adicionalmente en la carcasa (3); la primera disposición de diafragma comprende un ensamble de canal de retorno (23A) con una pluralidad de cuchillas de canal de retorno estacionarias (27A), que definen una pluralidad de veletas de retorno para redirigir gas comprimido desde una ubicación de salida del impulsor voladizo a una ubicación de entrada del impulsor entre cojinetes; la primera disposición de diafragma (25, 25X) aloja uno del primer cojinete y segundo cojinete (11; 13).
