  • Patent number: 10213875
    Abstract: A method for manufacturing a housing of a turbomachine, in particular a housing of a radial turbo compressor. The method includes the following steps: a) providing a hollow body that is closed in a circumferential direction and extends along an axis; b) coating the inner side of the hollow body with a corrosion-resistant layer that is more resistant to corrosion than the material of the hollow body; c) dividing the hollow body into two half-shells along the axis in a separation joint plane; d) assembling the housing by joining both half-shells and fastening both half-shells in the region of the separation joints, which were created by separation, by means of detachable fastening elements.

  • Patent number: 9273695
    Abstract: An arrangement having an annular seal extending about a machine axis, and a vessel for sealing an L-shaped gap extending along a circumferential direction between a main vessel body and a cover is provided. A radial section of the gap extends in the radial direction and circumferential direction, and an axial segment extends in the axial direction and the circumferential direction. A sealing chamber is provided in the region where the radial segment and the axial segment intersect, the chamber expanded radially and axially relative to the adjacent gap segments. A seal is disposed in the sealing chamber, and a greater pressure is present in the radial segment than in the axial segment, the pressure differential sealed by means of the seal. The seal includes a support ring disposed radially inward made of a first material, and a jacket element made of a second material.

  • Publication number: 20150016977
    Abstract: A turbomachine and a method for the assembly of the turbomachine with a housing and with a rotor, in which at least one cover of the housing is fastened to the rotor, and the combination is placed into a lower part of the housing and is then enclosed by an upper part of the housing, is provided. To attain centered mounting of the cover assembly and to thus prevent damage to the shaft seal, it is proposed that the combination, as it is placed in, is supported on at least one guide means in the housing, and the guide means forms a guide for the cover in the housing, by means of which guide the placed-in cover is held spaced apart from the housing lower part and the housing upper part with a radial assembly gap.

  • Publication number: 20130183147
    Abstract: A casing is provided having a longitudinal axis of a turbomachine, the axis extending along a rotor. The casing includes at least one jacket part extending along the longitudinal axis and at least one end-face cover. The cover is surrounded by the jacket part at least with a part of the axial extension of the cover. In order to reduce the need for radial clearance, without compromising the availability or safety of the operation of the machine, the cover has radial clearance with respect to the jacket part and at least two separate guide elements of the cover are provided on the jacket part in two different circumferential positions with respect to the longitudinal axis. The respective guide elements are designed such that they block a respective movement of the cover in the circumferential direction at least unidirectionally.
