Definitions

  • the present invention relates to the Verdiohterbau, in particular to impellers of centrifugal compressors.
  • the cover plate is made in one piece from a forging.
  • the impellers with such cover disks are characterized by the possibility of working at increased peripheral speeds (from 120 to 300 m / s).
  • the high peripheral speeds cause a bending deformation of the ring and the cover plate body as well as a radial deformation of the ring.
  • the changes in shape mentioned cause a radial displacement of the ring, through which enlarged gaps between the ring and the seals installed in the compressor housing must be provided.
  • the enlargement of the column leads to an increase in gas escapes and to a reduction in the efficiency of the compressor.
  • an impeller for centrifugal dihydrators which contains a main disc, blades and a cover disc, which cover disc consists of interconnected, cover disc body for gas flow guidance in the impeller and ring for the arrangement of seals (see the book by Bruk AD "Dymososy gazcoochistnykh sooruzheny” / Tongue fans in the gas cleaning plants /, Moscow, publisher “Maahinostroenie", 1984, p. 120).
  • the cover plate body is connected to the ring either by welding or riveting.
  • the impellers with the multi-part cover disc in which the connection of the deodorant disc body to the ring is carried out as mentioned, are less labor-intensive and metal-intensive, but have a high stress on the connection point of the cover plate body and the ring, which makes the use of these impellers for operation at peripheral speeds above 120 m / s impossible.
  • the present invention has for its object to develop an impeller of centrifugal compressors 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 thus the use of said impellers at peripheral speeds above 120 m / s is made possible.
  • the impeller for centrifugal compressors which are rigidly connected to one another, contains the main disc, rotor blades and cover disc, which cover disc consists of, connected to one another, cover disc body for gas flow guidance within the impeller and ring for arranging seals, the connection according to the invention of the cover plate body with the ring underneath
  • Training on the cover plate body and the ring of detachable mating surfaces is detachable and on the mating surface of the ring on the side of the rotor blades has a collar that protrudes into a recess in the recess on the mating surface of the cover plate body, the inside diameter of the cover plate body facing the diameter of the ring its counter surface by 1 to 1.5.10 -3. D o is smaller, where D means the inside diameter of the cover plate.
  • the impellers with the cover plates of this type can be used when operating at peripheral speeds that correspond to the peripheral speed of 120 m / s (up to 300 m / s).
  • the optimal sizes of the excess in the range between 1 and 1.5.10 -3 .D o , where D means the inside diameter of the cover disk.
  • the lower limit of the oversize fit 1.10 -3 .D o is due to the possibility of mechanical processing of the deodorant washer during its manufacture, since with an oversize less than 1.10 -3 .D o the mechanical processing of the deodorant washer is possible with any type of clamping.
  • the proposed impeller for centrifugal compressors shown in FIG. 1 contains a main running disk 1 and moving blades 2, which are manufactured as a whole with the main running disk 1 or welded (soldered) to it.
  • the cover disk 3 is rigidly connected to the rotor blades 2 by welding or soldering, which consists of, connected to one another, a cover disk body 4 for gas flow guidance within the impeller and a ring 5 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 Decksoheiben stresses 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 of 1 to 1.5.10 -3 .D o , which means that the Impeller the interaction of the cover plate body 4 with the ring 5 is excluded, the stresses in the connection of the counter surfaces 6 and 7 are greatly reduced and the use of the construction of the impeller during operation at peripheral speeds over 120 m / s (up to 300 m / s) enables becomes.
  • 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 said collar 8 and the ring recess 9.
  • the arrangement of the ring collar 8 in the ring recess 9 of the cover plate body 4 prevents the movements of the ring 5 in the axial and radial directions.
  • 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.
  • a plurality of gradations 15 are provided, which are used to install sealing elements (not shown).
  • the impeller for centrifugal compressors works as follows.
  • the annular collar 8 also prevents the movements of the ring 5 in the axial direction, which are caused by the end faces 11, 12, 13 and 14 of the collar 8, the ring rotation 9 and the blades 2 can be avoided.
  • the present invention can be used with the closed type rotary gears with best success.
  • the invention can also be used in the low-pressure impellers of centrifugal compressors (fans).

Abstract

Rotor, comportant un disque principal (1), des lames de travail (2) et un disque de couverture (3) constitué d'une plaque (4) et d'un anneau (5) reliés l'un à l'autre. La liaison de la plaque (4) et de l'anneau (5) peut être séparée le long des surfaces conjuguées (6 et 7), la surface (7) de l'anneau (5) étant pourvue d'un cordon annulaire (8) et la surface (6) de la plaque (4) ayant une rainure annulaire (9) dans laquelle est logé le cordon (8). Le diamètre interne (Do) de la plaque (4) est inférieur au diamètre (D) de l'anneau (5) le long de leurs surfaces conjuguées (6 et 7) dans un rapport de 1-1,5.10-3Do.
