摘要： A sealing system (200) for a centrifugal compressor includes a stator (220) having a seal housing (230), a seal (223) disposed in the seal housing (230) and having an abradable portion (225) along an inner circumference, a rotor (210) having a plurality of rotor teeth (215) configured to rotate within the inner circumference of the seal (223) and configured to create rub grooves (227) within the abradable portion (225), and a first spring (240) disposed between the stator (220) and the seal (210) and configured to facilitate axial movement of the seal (223) relative to the seal housing (230).
