Embodiment Construction

[0020] figure 1 The steam turbine 1 shown as an embodiment of a turbomachine basically comprises an outer housing 2 , an outer inner housing 3 arranged in the outer housing 2 and an inner inner housing 4 arranged in the outer inner housing 3 .

[0021] In the outer inner housing 3 and the inner inner housing 4 , a rotor 5 is mounted rotatably about an axis of rotation 6 . Flow channels 7 are formed between the outer inner housing 3 and the rotor 5 and between the inner inner housing 4 and the rotor 5 . For the sake of clarity, the individual rotor blades and guide blades are not shown in detail. The guide vanes are arranged on the inner inner housing 4 and on the outer inner housing 3 . On the rotor 5 the moving blades are arranged such that in the flow channel 7 the thermal energy of the steam can be converted into rotational kinetic energy. First, steam flows through a steam inlet region (not shown in detail) into the first flow region 8 which is arranged between the inn...

Abstract

#CMT# # / CMT# The turbo-engine has a rotor (5) rotatably supported around a rotational axis (6), and an internal inner housing (4) and an external inner housing (3) are arranged around the rotor. An outer housing (2) is arranged around the internal and external inner housings. A flow channel (7) for flow of a fluid medium is formed between the rotor and the internal and external inner housings. A sealing is arranged between the internal and the external inner housings. Tapping holes (16) for discharging fluid medium from the flow channel are arranged in the internal and external inner housings. #CMT#USE : # / CMT# Turbo-engine for use with steam tapping. #CMT#ADVANTAGE : # / CMT# The sealing is arranged between the internal inner housing and the external inner housing and the tapping holes for discharging fluid medium from the flow channel are arranged in the internal and external inner housings, and hence ensures an improved turbo-engine with variable tapping in axial direction. #CMT#DESCRIPTION OF DRAWINGS : # / CMT# The drawing shows a schematic sectional view of a steam turbine. 1 : Steam turbine 2 : Outer housing 3 : External inner housing 4 : Internal inner housing 5 : Rotor 6 : Rotational axis 7 : Flow channel 16 : Tapping holes.

Description

technical field [0001] The invention relates to a turbomachine comprising a rotor mounted rotatably about an axis of rotation, an inner inner casing and an outer inner casing arranged around the rotor, and an outer casing arranged around the inner inner casing and the outer inner casing body, wherein the outer inner housing is arranged around the inner inner housing along the region of the axis of rotation, wherein a flow region for the flow of the flow medium is formed between the rotor and the inner inner housing and the outer inner housing . Background technique [0002] A turbine can be understood to mean, for example, a steam turbine. Steam turbines generally have a rotatably mounted rotor and an inner housing arranged around the rotor. A flow channel is formed between the rotor and the inner housing. The casing of a steam turbine must be able to fulfill several functions. On the one hand, the guide vanes are arranged in the flow channels on the housing, and on the ...
