Definitions

  • the present invention relates to a housing for a turbomachine, in particular for a turbomachine.
  • the invention also relates to a mounting device for attaching a winding to such a housing.
  • Turbomachines in particular turbomachines, such as steam turbines, gas turbines, compressors, hydroturbines or hydraulic pumps, are exposed during operation to very high pressure loads.
  • turbomachines such as steam turbines, gas turbines, compressors, hydroturbines or hydraulic pumps
  • Such housings are generally assembled from two half-shells which abut each other in the region of an axial parting plane of the housing.
  • the axial orientation of the housing results from the orientation of a rotor of such a turbomachine whose axis of rotation defines the axial direction.
  • the two housing half-shells or housing halves must be fastened together with a comparatively large force in order to be able to pass the requirements in operation.
  • a construction with a single housing and a construction with a double housing which comprises an inner housing and an outer housing.
  • Various techniques are known for securing the two housing halves together.
  • shrink rings can be applied to the outside of the housing.
  • the disadvantage here is that the housing for this purpose must have a relatively large wall thickness.
  • the shrink rings have a relatively large dimension in the radial direction, whereby the housing as a whole builds relatively large. Creeping deformations that occur in the course of the operation of the turbomachine, here are relatively large, since the temperature gradient over the relatively large wall thickness is correspondingly large. This is especially true for an inner housing, since this is exposed from the inside of great heat and is cooled from the outside at the same time.
  • the invention deals with the problem of providing an improved embodiment for a housing of the type mentioned, which is characterized in particular by a reduced deformation of the housing during operation and / or by a reduced weight and / or characterized by reduced manufacturing and maintenance costs.
  • the invention is based on the general idea to fasten the two housing halves together by means of a winding, which wraps around the housing halves on the outside and which is formed with at least one tensioned tensioning cable, which consists of at least one wire.
  • the proposed construction according to the invention offers many advantages.
  • the winding can adapt almost optimally to the rotational symmetry of the housing, which enables an optimal distribution of force along the housing.
  • the housing can be made comparatively thin due to the homogeneous distribution of force, whereby the weight of the housing and the manufacturing costs can be reduced.
  • a thin wall thickness of the housing reduces temperature sensitivity and in particular reduces creep deformation due to temperature gradients.
  • the tension cable which can be loaded on a train, in particular may be formed by a wire formed from a plurality of wires, has in its pulling direction a significantly higher stability and creep resistance than the casting material of the housing halves. This is true even if the tensioning cable and the housing halves are made of the same material. This is due to the different sizes. This is likewise due to the cold processing of the tensioning cable, which is attributable to an advantageous internal material structure, in particular with regard to a fiber orientation. In addition, when using such a winding can be dispensed with mounting flanges, as well as heavy-duty preloading screws.
  • the outer housing can be made smaller accordingly.
  • the comparatively homogeneous distribution of force along the sealing surface in the parting plane, in which the two housing halves abut each other, allows a higher pressure load and / or temperature load of the housing even during transient operating conditions, which reduces the sensitivity of the housing to plastic deformation of the sealing surface.
  • the use and provision of tension cables with a few standard diameter diameters is sufficient. Expensive custom-made flange screw connections can be dispensed with.
  • tensioning rope can be easily stored and quickly available.
  • the use of such windings for fastening the housing halves together also eliminates the need for expensive assembly processes and dismantling methods, as are required, for example, when attaching and detaching shrink rings.
  • the reliability of a fixture made with the help of the winding is increased, which makes the operation of the so equipped Turbomachine simplified.
  • An important advantage of the attachment according to the invention can also be seen in that the holding forces are introduced not only in the axial direction, but also radially and circumferentially substantially homogeneously distributed in the housing, whereby a deformation of the cross section due to high pressures and temperatures is reduced , An elliptical deformation of the per se circular cross-section can be significantly reduced or even avoided.
  • clamping screws extend within the respective mounting flange and are thereby arranged comparatively close to the inner surface of the respective housing, which in particular limit a hot gas path of a gas turbine or a hot high-pressure region of a steam turbine.
  • the tension cable is located on the outside of the respective housing and can also be exposed directly to cooling. Due to the significantly lower temperatures in the tensioning cable and the associated increase in material strength, this can at the same working conditions a significantly better clamping of the two housing halves against each other ensure as a corresponding flange connection with clamping screws. Overall, it is also possible to reduce the manufacturing costs of such a housing. Further, the improved reliability of the proposed attachment allows for increased maintenance intervals, thereby reducing downtime of the housing-equipped turbomachinery during its lifetime.
  • a mounting device for attaching a winding to a housing is characterized in that a fixedly attached to the housing or attached abutment means is provided on which at least one clamping device can be supported, which serves to introduce a tensile force in the tensioning cable. The forces required for clamping can thus be supported directly on the housing, which reduces the expenditure on equipment for producing the desired prestressed winding.

  • Fig. 12 includes the same clamping device as Fig. 1 1, but with the difference that still a spring 41 is mounted on the axial slide 37. With this spring 41 it is easier to adjust the tension of the tensioning cable 7, because then a small rotational movement of the coil 37 causes only a small change in the tensile force in the tension cable 7. Without this spring 41, the change in tensile force would be much greater and therefore control of the drive of the spool 37 would be more difficult.
