| Abstract: | The new aerodynamic foil journal bearings with elastic support and spiral grooved thrust bearings have been applied to a turboexpander associated with 150m 3/h oxygen plant.They can support the rotor revolving at 12 16×10 4rpm which overspeeds by 14%.By using these gas bearings,smooth operation is obtained.In addition,the performance of spiral grooved thrust bearings has been studied.The experimental results have proved that the application of this kind of self acting gas bearings to the cryogenic turboexpanders is feasible. |
