Abstract:
A method for providing an axial thrust compensation on a turbomachine, which comprises:providing a turbomachine having an outer casing, a shaft, and an inner casing with an exterior region, a part of the exterior region of the inner casing defining at least one first area having two partial areas;separating the two partial areas with at least one separating means for providing a compensating axial thrust; andsubjecting the turbomachine to a fluid flow having a pressure flowing through the turbomachine causing an axial force in a longitudinal direction of the shaft acting at least on the inner casing, subjecting each of the two partial areas of the at least one first area to different pressures for generating the compensating axial thrust, and a separation between the different pressures brought about by the at least one separating means.
