By applying material on only one side in the case of a revision, seal rings can be easily rebuilt and reused.

Repaired ring and method for repairing a ring which is used for sealing purposes

A method is provided for carrying out a sound test for detecting and/or analyzing material faults and/or mounting faults of at least one component, in which the component is excited, by striking, to experience vibrations which generate soundwaves, after which the generated soundwaves are detected and conclusions are drawn about material faults and/or mounting faults on the basis of the detected soundwaves, wherein the striking of the component and the detection of the vibrations are carried out using an endoscope device. In addition, embodiments of the present invention relates to an endoscope device which is configured to carry out the method.

Method for carrying out a sound test of atleast one component and endoscope device used for the same

A turbomachine including a rotor and an inner interior housing an outer interior housing and an exterior housing, wherein the turbomachine has a first flow and a second flow arranged opposite the first flow for a high-pressure blading or medium-pressure blading, wherein the inner interior housing is made of a higher quality material tan the outer interior housing and solely accommodates the high-pressure and medium-pressure inflow regions including the balance piston is provided.

Steam turbine in a three-shelled design

A turbomachine comprising a rotor, an inner housing, and an outer housing is proposed. The inner housing is arranged around the rotor and the outer housing is arranged around the inner housing, An encapsulation is arranged around the inner housing. An annular channel and holes into a chamber are provided between the encapsulation and the inner-housing outer surface, and steam flows out again via holes which are situated in the encapsulation.

Steam turbine having a cooling apparatus

A steam turbine has a two-shell housing, including an outer casing and an inner casing arranged therein, as well as a pipe that extends through the outer casing for supplying and/or removing steam to or from the inner casing, the pipe being provided with a pair of apertures arranged opposite each other on the inner casing. According to the invention, a first steam supply or discharge pipe can be connected to a first aperture, and the second aperture is closed by a cover.

Steam turbine

The invention relates to a turbine machine, in particular, a steam turbine, comprising an inner housing, a turbine shaft, mounted such as to rotate, characterized in that the inner housing and the turbine shaft are produced from differing materials. The turbine is made from a chrome steel with 9 to 12 wt. % of chromium and the inner housing from a chrome steel with 1 to 2 wt % of chromium.

Turbomachine

In a machine having a shaft with a shaft axis, an outer region, and a shaft seal, a component is provided for the shaft seal. The component has a cast part formed of a first metallic material directed along the shaft axis and has an inner wall shaped, at least in regions, in a circumferential direction relative to the shaft axis, and an outer wall directed towards the outer region. A fluid guide is disposed and formed in the cast part and runs in the circumferential direction, at least in regions, and opens into the inner wall. At least one fluid conduit formed of a second metallic material fluidically connects the inner wall to the outer region. The fluid conduit is also fluidically connected to the fluid guide.

Housing for a turbomachine

In order, in a particularly simple way, to allow multiple separation and connection of line sections of a line, through which a hot and highly compressed medium flows, in particular a pipeline, through which steam flows, there is provided a double-walled flanged connection. The double-walled flange connection is formed of an outer flange and an inner flange, between which an interspace, through which a cooling medium is capable of flowing, is formed. The apparatus is particularly suitable for the connection of line sections of a steam turbine.

Apparatus for the connection of line sections

A turbine shaft for a steam turbine, in particular having a high-pressure and an intermediate-pressure turbine section. The turbine shaft has in its interior a cooling line for passing cooling steam. The cooling line is connected, on the one hand, to an outflow line and, on the other hand, to an inflow line. In this way, steam cooling of the turbine shaft can be achieved by feeding steam from the high-pressure turbine section via the inflow line to the intermediate-pressure turbine section through the outflow line. The invention also relates to a method of cooling a turbine shaft of a steam turbine.

Turbine shaft of a steam turbine having internal cooling, and also a method of cooling a turbine shaft

A device for thermally insulating casing parts of a steam turbine contains a shim element that can be inserted into a bearing region of supporting bearings of the casing parts. The supporting bearings face one another and the shim element has a number of holes formed therein.
