Definitions

  • Radial turbofan energy machines are usually provided as a compact unit with a drive or output on a common platform. During maintenance or inspection on the radial turbofan energy machine, an opening of a housing is usually mandatory, and it is preferable to avoid an expense for the other connected units. In particular, a drive or output of the radial turbofan energy machine should not have to be moved.
  • housing are preferably in pot construction designed so that there is no parting line extending along the central axis or axis of rotation on the housing. Since the machines are usually placed horizontally, this type of parting joint is then also referred to as a horizontal parting line.
  • a parting line is associated with local, necessary in the region of the parting material concentrations, on the one hand space, on the other hand require additional material and also cause stiffness jumps in the housing.
  • the avoidance of the horizontal parting line also has the advantage in the pot construction that under the mechanical and thermal loads on the housing no asymmetrical deformations occur in the direction of contact, which can lead to alignment problems and to leaks in the parting line.
  • reference to an axis always means reference to the central axis of extension of the housing, unless otherwise specified.
  • this central extension axis is usually almost or completely identical to a rotational axis of a rotor of the radial fluid energy machine, for which the housing has been produced by the method according to the invention and by means of the housing model according to the invention.
  • the preferred application of the invention are the housing of radial turbocompressors, in particular designed as a pipeline compressor for the compression of natural gas.
  • the housing of a radial turbofluid energy machine according to the invention can also be used for an expander. In essence, such a design is identical with reversal of the flow direction.
  • high pressure and low pressure are to be understood in the context of this document such that during normal operation of the machine according to the invention in the region of low pressure a lower pressure prevails than in the area of high pressure.
  • Low pressure does not necessarily mean that the prevailing pressure level is in the order of magnitude of the atmospheric pressure or below.
  • FIG. 5 a conventional radial turbofluid energy machine in the form of a centrifugal compressor is shown schematically as a longitudinal section.
  • the radial turbofluid energy engine RFM shown comprises a rotor R which extends along an axis X and comprises the impellers IMP, specifically in the flow direction: a first impeller IMP1, a second impeller IMP 2 and a third impeller IMP3.
  • a process fluid PF passes through the inlet of a housing CAS in the interior of the machine and is compacted by means of the impeller IMP and by means of stationary between the impellers arranged intermediate floors to a final pressure.
  • the housing CAS essentially comprises a housing jacket CCV, on a low-pressure side a low-pressure cover LPC and on a high-pressure side a high-pressure cover HPC.
  • the high-pressure spiral HSP claimed so much radial space that the housing CAS is bell-shaped, optimizing the material requirements and space requirements, the larger outer and inner diameter is provided on the high pressure side due to the high pressure spiral HSP.
  • the high-pressure lid HPC of the housing CAS must be designed, in particular, with regard to the diameter and, due to the pressure, also be adequately dimensioned in terms of its thickness and attached to the housing jacket CCV in a complex manner.
  • the diameter of the high-pressure spiral and thus the high-pressure lid shapes the overall size of the machine and causes high costs.
  • the lateral surface is also not nearly cylindrical and walls of the lateral surface are bent.
  • the bell-shaped due to the dimensions of the high pressure spiral HSP inner bundle IB can be introduced only along a first axial mounting direction DX1 in the housing CAS or the housing shell CCV.
  • the introduction of the inner bundle IB takes place through the opening of the housing shell on the part of the HPC high-pressure cover.
  • Due to the bell shape also on the inner diameter of the housing CAS support of the inner beam IB in the housing shell is not possible during assembly, so that one extends the inner beam IB along the rotor with a so-called horsetail and outside of the housing CAS on the low pressure side or on the Low pressure cover the horsetail (eg Fig. 3 .
  • Another disadvantage of the conventional construction of the radial turbofluid energy machine RFM according to FIG. 5 consists in the enormous dimensions of the high-pressure lid HPC, which is oriented in its diameter at the belonging to the inner beam IB high-pressure spiral HSP.
  • the large diameter also requires a massive thickness of the high-pressure lid HPC and requires particularly reliable stationary seals of the high-pressure lid HPC to the housing shell CCV, the housing shell CCV in the high pressure area is additionally weakened by the attachment of the high-pressure lid HPC screws SCR.
  • the high weight of the HPC high pressure lid requires
  • special measures also in the context of assembly for supporting and guiding the high-pressure lid HPC and a special care so that the seal of the high-pressure lid HPC is not destroyed in the joining process.
  • the invention has set itself the task of improving the housing cast model, the housing series and the method for producing a cast housing of a radial turbofluid energy machine so that at least some of the above-mentioned disadvantages are at least partially avoided.
  • the invention proposes a method for producing a cast housing of the type defined above with the additional features of the method claim.
  • the invention proposes a novel housing casting model.
  • the invention proposes a novel housing series.
  • the particular advantage of the method according to the invention lies in the variability of the design of the housing required for the radial turbofluid energy machine, wherein the housing is advantageously provided as a cast component in terms of flow and does not have to be provided with the same number of complete cast housing models for a large number of geometries for the high-pressure spiral.
  • the various selectable high-pressure housing jacket models and low-pressure housing jacket models only have to have an identical geometry or cross-sectional geometry at the end faces facing one another and to be joined, so that a largely smooth transition between the assembled model parts is guaranteed. If one goes from the in FIG.
  • Another advantageous development of the invention provides that when assembling from different high-pressure housing jacket models can be selected which different Hochlichgephaseusemantelmodelle fit to the same high-pressure model cover or provide the same opening to be closed by means of the high-pressure model cover.
  • Another advantageous development of the invention provides that, when assembling different low-pressure housing jacket models, it is possible to select which different low-pressure housing jacket models match the same low-pressure model cover or provide the same opening to be closed by means of the low-pressure model cover.
  • the housing model casing is designed such that the cast housing to be produced therewith is formed undivided in the axial direction.
  • the housing model casing is designed such that the cast housing to be produced therewith is also designed to be undivided in the circumferential direction.
