Definitions

  • the present invention relates to the impeller of a centrifugal compressor.
  • a known impeller for centrifugal compressors has a main disc, blades and a cover disc, which consists of the cover disc body for gas flow guidance in the impeller and a ring for arranging seals (VF Ris, "Centrobeinye kompressornye masiny” (centrifugal compressor machines), Leningrad, publisher “Masinostroenie", 1981, pp. 35, 103).
  • the cover plate is made in one piece from a forging. Impellers with such cover disks can be operated at increased peripheral speeds of 120 to 300 m / s. However, due to the undivided design of the cover plate from a forging, a considerable amount of metal of 85% has to be cut, so that the metal utilization rate only reaches 15%.
  • Another known impeller of a centrifugal compressor has a main disc, rotor blade and a cover disc, which consists of a cover disc body for gas flow guidance in the impeller and a ring connected to this for the arrangement of seals (AD Bruk, "Dymososy gazoocistnyx sooruzeny” (suction tongue fans in gas cleaning systems), Moscow , Publisher “Masinostroenie", 1984, p. 120).
  • the cover disk consists of a cover disk body for gas flow guidance within the impeller and a ring which is detachably connected to this for the arrangement of seals.
  • the ring is welded to the rotor blades and the cover disk body is held in a form-fitting manner in the ring by means of an axially projecting collar, and is welded to the rotor blades in one of the embodiments or riveted in another embodiment to these, permitting relative radial expansions.
  • This design does not reduce the stresses on the connection point between the ring and the cover plate body and, moreover, the construction can only be used if the moving blades extend into the suction mouth.
  • the present invention has for its object to develop an impeller of a centrifugal compressor in which the connection of the cover plate body to the ring is carried out in such a way that the stresses at their connection point are reduced and an operation at peripheral speeds over 120 m / s is made possible.
  • the task is thereby solved that according to the invention the connection of the cover plate body and the ring is carried out with the formation of associated counter surfaces on the cover plate body and the ring and on the counter surface of the ring on the side of the rotor blades has a collar which projects into a recessed ring recess on the counter surface of the cover plate body, whereby the inside diameter of the cover plate body is smaller by 1 to 1.5 - 10 -3 D o compared to the diameter of the ring on its counter surface, where D o means the inside diameter of the cover plate body.
  • the impellers with cover plates of this type can operate at peripheral speeds of far more than 120 m / s (up to 300 m / s) operate.
  • the optimal sizes of the oversize are in the range between 1 and 1.5 ⁇ 10 -3 D o , where D o means the inside diameter of the cover plate.
  • the impeller of a centrifugal compressor shown has a main disc 1 and blades 2, which are manufactured as a whole with the main disc 1 or are welded or soldered to it.
  • the cover plate 3 is rigidly connected by welding or soldering, which consists of a cover plate body 4 for gas flow guidance within the impeller and a ring 5 connected thereto for installing sealing elements (not shown in the drawing) which prevent gas leaks.
  • the cover plate body 4 and the ring 5 are connected to one another to form mating surfaces 6 and 7, each associated with the cover plate body 4 and the ring 5.
  • the inner diameter D o of the cover plate body 4 is smaller than the diameter D of the ring 5 on its counter surfaces 6 and 7.
  • the difference in the diameters D o and D is in the range from 1 to 1.5 - 10 -3 D o , resulting in operation the interaction of the cover disk body 4 with the ring 5 of the impeller is excluded, the stresses in the connection of the counter surfaces 6 and 7 are greatly reduced and the operation of the impeller at peripheral speeds over 120 m / s (up to 300 m / s) is made possible.
  • a collar 8 is provided on the side of the blades 2. This collar 8 protrudes into a recess 9 in the counter surface 6 of the body 4 of the cover plate 3. An annular gap 10 is present between the collar 8 and the ring recess 9.
  • the end faces 11 and 12 of the ring collar 8 and the ring recess 9 and the end faces 13 and 14 of the ring collar 8 and the blades 2 prevent the movement of the ring 5 in the axial direction.
  • the outer surface of the ring 5 has a plurality of gradations 15, which are used to install sealing elements (not shown).
  • the ring collar 8 also prevents movements of the ring 5 in the axial direction, namely by touching the end faces 11, 12, 13 and 14 of the ring collar 8, the ring rotation 9 and the moving blades 2.
