Definitions

  • the invention relates to a side channel compressor according to the preamble of claim 1.
  • Such a side channel compressor is known from DE-U-87 04 066.
  • a stripper protruding radially into this sealing gap is arranged in the radial sealing gap section formed between a section of the blade ring projecting laterally beyond the hub part of the impeller and the housing under this section, by means of which a dirt deposit which leads to a blocking of the impeller is to be prevented.
  • the object of the invention is therefore to design a side channel compressor according to the preamble of claim 1 so that even when pumping gases loaded with fluff or fibrous particles, a blocking of the impeller due to a deposition of these particles in the sealing gap is prevented.
  • slot-like recesses are provided on both sides of the impeller, which are offset from one another in the circumferential direction in order to avoid an impermissible reduction in the mechanical strength of the impeller.
  • a possible clogging of the slot-like recesses themselves is counteracted by the fact that at least one depression in the circumferential direction extending at a multiple of the slot groove width is formed on the housing at least in the area of the axial sealing gap section.
  • the housing of a side channel compressor consisting of two housing halves 2 and 3 is designated.
  • an impeller 4 is rotatably mounted by means of a shaft 5 which can be coupled to a drive, not shown in the drawing.
  • the impeller of the side channel compressor shown in FIG. 1 consists of a disk-shaped hub part 6 and a blade ring 7 arranged on its outer circumference.
  • the blade ring 7 has a greater width than the hub part 6, so that it is on both sides in the direction of the axis of rotation of the impeller 4 towered over.
  • the two housing halves 2 and 3 are designed such that they engage under the laterally projecting sections of the blade ring 7.
  • the dimensions of the housing halves 2 and 3 are made in relation to the impeller 4 such that a radial sealing gap section 10 and an axial sealing gap section 11 between the laterally projecting section 8 of the blade ring 7 and the engaging part 9 of the housing halves 2 and 3 consists. This ensures contactless rotation of the impeller 4 relative to the housing halves 2 and 3.
  • a larger leakage current can form via the slots 14 and the slot groove 15, which effectively represent an expansion of the sealing gap sections 10 and 11. This leads to a higher flow rate of the leak gas. As a result, lint-like or fiber-like dirt particles which have entered the cavity 17 are conveyed back into the side channel 16 through the slot groove 15 and the slot 14 in the region of the inlet opening 19.
  • depressions 20 are formed on the housing halves 2 and 3 in the region of the axial sealing gap section 11. Such depressions are only shown on the housing half 2 in the drawing. These depressions 20 extend in the radial direction approximately over the radial length of the slot grooves 15 and in the circumferential direction by a multiple of the width of the slot grooves 15. Through the depressions 20, a swirling of the leakage flow is achieved in the slot grooves 15 and thereby a deposition of dirt particles prevented. This swirling also acts back on the depressions 20 and thus also prevents dirt particles from being deposited in these depressions 20.
  • the depressions 20 are round, so that they can be produced easily.
  • FIG. 2 shows another embodiment of a side channel compressor, in which the blade ring 7 of the impeller 4 and the housing halves 2 and 3 do not overlap.
  • the blade ring 7 of the impeller 4 and the housing halves 2 and 3 do not overlap.
  • the blade ring 7 and the hub part 6 of the impeller 4 there is therefore only one axial sealing gap 21.
  • a groove 22 running parallel to the axial sealing gap 21 is provided in this transition area.
  • This groove 22 fulfills the same functions as the slots 14 and slot grooves 15 provided in the exemplary embodiment according to FIG. 1.
  • several grooves 22 on both sides of the impeller and also depressions 20 in can be distributed over the circumference of the impeller 4 the wall of the housing halves 2 and 3 may be provided.
