Abstract: The invention relates to a turbo-machine comprising a rotor, a stator, and a flow channel for an actuating fluid used to drive the rotor. Said turbo-machine comprises a magnet for producing a pre-determinable magnetic field in the flow channel. The invention also relates to a method for operating a turbo-machine comprising a rotor, a stator, and a flow channel. According to the invention, an ion-containing actuating fluid flows through the flow channel and a defined magnetic field is produced in the flow channel, ions being deviated in the magnetic field.

Abstract: The invention relates to a turbine installation, especially a steam turbine installation. The inventive turbine installation comprises at least two partial turbines, each of the partial turbines having a rotor disk that extends along the main axis. Said rotor disks are rigidly interlinked to a shafting. At least one of the partial turbines has an inner housing that concentrically encloses the rotor disk and that is mounted so as to be axially displaceable in a bearing area. To allow for an axial displacement a push element transmits the axial force and is linked with the inner housing. In order to allow the inner housing to be axially displaced as easily as possible, the bearing area has a bearing device with a static friction and/or sliding friction that is so low that the axial misplacement that spontaneously occurs when the static friction is overcome during displacement of the inner housing is smaller 2 mm.

Abstract: The invention relates to a steam line closing valve for closing a steam line, especially in a steam turbine plant between a first partial turbine and at least one second partial turbine that is operated at a lower pressure than the first partial turbine. According to the invention, the steam line closing valve is subdivided into a plurality of elements that cooperate to cover the cross-section of the steam line, thereby reducing the moment of inertia Iy of the elements.

Abstract: In previously known steam turbines (1) a rotor is either only cooled passively or is cooled actively only to a limited extent in a region where the working medium flows in. As the loading on the rotor increases as a result of high steam parameters of the working medium, sufficient cooling of the steam turbine rotor is no longer ensured. The proposed steam turbine rotor (21, 30, 75) extends along an axial extent (25, 34) and includes: an outer side (26a) which adjoins an outer space (27a, 35) which is intended to receive a main flow (27, 36) of a fluid working medium (8), a first A location (30a) along the outer side (26a), at which a first blade (41a) is held, a second location (30b) along the outer side (26a, 33), at which a second blade (41b) is held, the second location (30b) being arranged behind the first location (30a) along the axial extent (25, 34).

Abstract: A steam turbine (20) having a rotor (21) which is provided with a number of rotor blades (22) and, together with a number of guide vanes (24), is arranged inside a casing shell (30) formed from a number of casing segments is to be designed to be suitable for operation with relatively high steam parameters, i.e. in particular with a particularly high steam temperature and a particularly high steam pressure. For this purpose, according to the invention active cooling of the casing shell (30) is provided, at least one of the casing segments which form the casing shell being provided with a number of integrated cooling channels (29). When the steam turbine (20) is operating, therefore, the casing shell (30) is actively cooled with a cooling medium by the latter being supplied to the cooling channels (29).

Abstract: The invention relates to a steam line closing valve (14) for closing a steam line (20), especially in a steam turbine plant (10) between a first partial turbine (11) and at least one second partial turbine (15) that is operated at a lower pressure than the first partial turbine (11). According to the invention, the steam line closing valve (14) is subdivided into a plurality of elements (25a, 25b, 25c, 25d) that cooperate to cover the cross-section of the steam line (20), thereby reducing the moment of inertia Iy of the elements (25a, 25b, 25c, 25d).

Abstract: A sealing configuration is provided for sealing off a first region from a second region through which a fluid can flow and which can be kept at different pressures. The sealing configuration has a deformation region and a sealing surface connected thereto. The sealing surface is spaced apart from an opposing surface by a sealing gap. The width of the sealing gap depends on a deformation of the deformation region as a result of a differential pressure. The sealing configuration preferably serves to seal off a turbine shaft from a turbine casing or a moving blade from a turbine casing.

Abstract: To connect piping sections of a pipeline through which a hot and highly compressed medium flows, a number of tension elements are provided. The tension elements extending with their tension shanks in a longitudinal direction of the pipe between shaped elements which are provided at the pipe ends and are adjacent in the circumferential direction of the pipe. Shaped parts are provided at the ends of the tension shank and extend on both sides of the tension element in its transverse direction engaging behind the shaped elements in the circumferential direction of the pipe.

Abstract: A turbine casing includes a multilayer casing wall in which an intermediate layer in the form of a non-metallic bulk material, preferably sand, is provided between an inner layer and an outer layer, to cope with high steam states. A method of manufacturing a multilayer turbine casing includes inserting a core representing an intermediate layer into a casting mold while forming a cavity for the inner layer and/or the outer layer. The cavity is then filled with a casting material, with the core expediently remaining as the intermediate layer in the casing wall. Alternatively, first of all a U-shaped profile part is made and an intermediate space formed by the outer layer and the inner layer is filled with the bulk material.

Abstract: The thread of a first component extends along a thread axis and has a thread structure for meshing engagement into a counterthread of a second component having a counterthread structure, for making a screw connection. The elastic and/or thermal deformation behavior of the first component and of the second component are different from one another. The thread structure is configured with an anticipation of deformation, in order to compensate for an elastic and/or thermal deformation under a predeterminable thermomechanical load, and a cylindrical thread segment of constant diameter. There is provided a thread segment, axially adjacent to the cylindrical thread segment, with a diameter that varies along the thread axis. The thread assembly is utilized in a screw connection for a high application temperatures.
