Abstract (en)
[origin: WO2011076668A2] Systems and methods for dynamically balancing axial loads in centrifugal compressors (10) to reduce residual axial loads on the bearings (20) used therein are described. A sensor or probe (42) detects a parameter associated with the axial load acting on the bearing (20). Based on the detected parameter, the pressure in a balance chamber (34) is controlled to adjust the compensating axial force generated by a balance drum (28).
