FIELD: machine building.
SUBSTANCE: system and method of dynamic balancing of axial force for centrifugal compressors (10) is described to reduce axial loads on bearings (20). Transmitter or probe (42) measures the parameter linked with the axial load acting on the bearings (20). Based on the measured parameter the pressure in the balancing chamber (34) is controlled to regulate the compensating axial force created by the balancing drum (28).
EFFECT: improved design.
