Definitions

  • the invention relates to a side channel machine.
  • a side channel compressor is known from DE-A 22 44 933, in which a band is inserted into an annular groove provided in the housing and extends against the end face of the support ring.
  • the band is aligned in the ring groove in such a way that the smallest possible gap between the end face of the support ring and the end of the band projecting from the ring groove results. This is intended to keep the so-called gap losses as small as possible.
  • the disadvantage here is that the manufacture of such a sealing device is very complex. Aligning the tape to achieve a uniform and narrow gap creates considerable difficulties. In the circumferential direction of the side channel compressor, a gap remains at the joint between the belt and the support ring, which still leads to pressure losses.
  • a side channel compressor which has a radially extending sealing ring on the inner circumference of the axially projecting part of the support ring, which rests on the axially projecting part of the support ring and by means of a retaining ring against one provided on the housing of the side channel compressor Contact surface is kept clamped.
  • the disadvantage here is the complex production and the large number of parts for realizing such a sealing device.
  • the invention is therefore based on the object of designing a side channel machine in such a way that there is an improved sealing of the side channel and an associated increase in efficiency of the side channel machine with less assembly and production outlay.
  • this object is achieved by a side channel machine with at least one impeller rotatably arranged in its housing, which has a support ring which is equipped with conveyor blades and which projects axially at least on one side with respect to the impeller axis with a hub part supporting it and connecting it with a drive shaft , at least in the area of the support ring between the impeller and the housing existing gap at least one edge-forming contour is provided, which serves to seal this gap, the contour being worked into the housing and / or the support ring.
  • the arrangement according to the invention of such a contour in the area of the gap creates a powerful and long-term stable sealing device.
  • An advantage here is that no additional parts have to be used, fixed and assembled to produce such a sealing device. This reduces the assembly time and the cost of storage for such sealing devices.
  • tests have shown an almost temperature-independent gap seal.
  • the same coefficients of expansion are present, and thus, regardless of the operating time of the side channel machine, a sealing system which ensures a long-term stable characteristic of the side channel machine during its operating time. An unwanted change in the working point of the side channel machine with increasing operating time is thus almost impossible, since there are no friction effects between the components forming the sealing device.
  • the contour continues essentially in the circumferential direction of the side channel machine.
  • the contour advantageously has a rectangular, trapezoidal and / or triangular shape.
  • the shape of the contour depends, among other things, on the selected manufacturing process, the media to be conveyed and the material of the housing and / or support ring.
  • the contour itself has a step-like course on the housing or on the support ring.
  • the contour on the housing and / or support ring is advantageously placed where production is particularly simple and can be carried out with little effort and where the sealing effect is best developed.
  • the housing of a double-flow side channel machine according to FIG. 1 is essentially formed by two housing halves 1, 2.
  • the housing halves 1 and 2 enclose an impeller 4 which is arranged on a drive shaft, not shown in the drawing.
  • the impeller 4 has on its outer circumference a support ring 5 on which the conveyor blades 6 of the impeller 4 are arranged.
  • the support ring 5 is arranged in a hub part which is plugged onto the drive shaft and is connected to it in a rotationally fixed manner and not shown in detail. Between the support ring 5 and one of the housing halves 1 or 2 there is a gap 3 which leads to gap losses and which must be sealed during operation.
  • each a corner recess X, Y is provided on the end face, in which there is advantageously a circumferential contour of the support ring and / or housing.
  • the contours are easy to produce, particularly in these corner cut-outs, by turning or milling.
  • FIG. 2 to FIG. 6 show possibilities for forming such contours 7 with an essentially rectangular course.
  • the contour 7 can also have a triangular or trapezoidal shape. Any combination of these contours 7 is also possible. It is crucial, however, that edges form in the area of this gap 3, so that the effect of a labyrinth seal is established.
  • a contour with a radius of approximately 0.5 mm or less is already defined as the edge, with a “sharper” edge resulting in a comparatively better sealing effect.
  • FIG. 7 and FIG. 8 show, in principle, stair-shaped contours 7, which essentially represent a repetition of a previously existing contour course and thus reinforce the labyrinth sealing effect.
  • FIG. 9 and FIG. 10 show further contour designs which, however, also serve to seal the gap 3 like the contour profiles described above.
  • Figures 3 and 5 are particularly suitable for different materials of the housing and the support ring 5, as with different coefficients of expansion (particularly housing effectively ⁇ ragring ⁇ ) on the basis of the clear width of the wound gap 3 in addition to the labyrinth seal effect a frictional contact of a housing half 1, 2 with the Support ring 5 is also avoided during longer operating times of the side channel machine.
  • No additional sealing elements have to be introduced and fixed in the gap 3 during the assembly or maintenance work.
  • Even during operation of the side channel machine there is a more than adequate sealing effect, since the thermal expansion coefficients of the materials of the housing halves 1, 2 and support ring 5 are almost identical. With identical materials, the expansion coefficients are the same and the sealing effect is improved again.

Abstract

Machine à canal latéral dotée d'au moins un rotor (4), placé rotatif dans son logement (1, 2), qui possède une bague de support (5) sur laquelle sont montés des godets de transport. La bague de support dépasse, au moins sur un côté et axialement par rapport à l'axe du rotor, d'une partie moyeu qui porte ladite bague de support et qui la relie à un arbre d'entraînement. Au moins dans la zone de la bague de support (5), entre le rotor (4) et le logement (1, 2), se trouve un espace (3) qui comporte au moins un profil (7) formant une arête. Ledit profil (7), qui sert à fermer ledit espace (3) de manière étanche, est constitué d'un seul tenant avec le logement et/ou avec la bague de support (5). La conception de la machine à canal latéral selon la présente invention permet d'améliorer l'efficacité de ladite machine, pour une facilité de fabrication et de montage accrue.
