ABSTRACT:
Apparatus for automatically monitoring and adjusting the axial thrust acting upon the rotor assembly of a rotating machine having an adjustable balancing mechanism for balancing the axial load acting thereon. A pair of surfaces on the rotor structure and a pair of flow circuits are arranged to direct a pressurized fluid against each surface. The back pressure is each circuit is monitored to determine when the axial forces are unbalanced and the data applied to a control mechanism for automatically balancing the axial forces acting on the rotor structure.
