Definitions

  • the invention relates to a side channel compressor, with at least one rotating in a split impeller housing Impeller, on which impeller housing at least two circumferential, circular sector-like connection areas are located, each of which has at least one inlet or an outlet opening on both in the axial direction of the impeller opposite sides of the impeller housing having.
  • Such a compressor is known from DE-C-43 41 266.
  • the connection areas only have an inlet opening or an outlet opening. So that can Pipes to be connected to the side channel blower only brought to the compressor housing from one direction become.
  • DE 2 721 233 describes one of several compressor stages existing side channel blower known, in which the each consisting of two housing halves Compressor stages are arranged axially next to one another and axially aligned inlet and outlet openings the same Have shape and size. So you are in the piping concentrated or it must already be in the manufacture or Purchase of a compressor the connection direction for the Pipelines are known or specified.
  • the invention has for its object a side channel compressor To be designed so that a connection of the necessary Piping in different directions is possible.
  • each connection area additionally in an essentially radial direction of the impeller each an inlet or Outlet opening.
  • This is a connection in one or other axis direction possible.
  • Multi-stage compressors are created by stringing together individual ones Housing formed.
  • connection areas with regard to their axial Width at least up to the parting plane of the impeller housing, then a direct connection of the corresponding involvement.
  • Outlet openings of the individual compressors possible because the Openings lie directly against each other in the axial direction and therefore no pipe parts required as an intermediate connection are.
  • connection areas become one Terminal block are summarized. This results in a higher mechanical strength.
  • the series connection is more than two compressors possible
  • the impeller housing of the individual compressors by a multiple of one Angular distance can be rotated against each other. So that at a connection of the pipes to the in the circumferential direction side of the connection areas lying on the impeller housing the impeller housing in a the direction of the the pipes to be connected are rotated accordingly become.
  • connection block In that the inlet and outlet openings of the connection block are each surrounded by a support surface, the connection of any components, e.g. Pipelines, Filters, silencers, valves or caps enables in a simple manner.
  • any components e.g. Pipelines, Filters, silencers, valves or caps
  • inlet and outlet openings in different directions 6 and 7 are used for connecting the pipes created more degrees of freedom.
  • the pipelines which are due to structural conditions on Location of the side channel blower can be determined the most convenient inlet or outlet opening 6 or 7 be selected for the connection of the pipeline. They don't required openings 6 and 7 are each one Cover 9 closed.
  • sealing surfaces 10 At the end faces of the housing halves 3 and 4 are over their Sculpted evenly distributed sealing surfaces 10. Of the Angular distance 11 of these sealing surfaces 10 corresponds to each other as well as opposite the inlet or outlet opening 6 or7 the angular distance between these two openings 6 and 7. The sealing surfaces 10 also correspond in shape and size of the shape and size of the inlet and outlet openings, respectively 6 and 7.
  • FIGS. 3 and 4 each show two flows in series switched side channel compressors 12 and 14.
  • the to be compressed Gas is, as indicated by an arrow, over a Pipe section 8 of the inlet opening lying on the circumference of the impeller housing 6 of the first side channel compressor 12 supplied.
  • the other on the outer end face 13 of the impeller housing lying inlet opening 6 is closed by a cover 9.
  • the impeller housing of the second side channel blower 14 is such an angular distance corresponding between the inlet and outlet opening 6 and 7 Angle to the impeller housing of the first side channel blower 12 twisted that on the corresponding Front end inlet opening 6 of this second side channel compressor 14 with the on the inner face of the Impeller housing of the first side channel compressor 12 lying Outlet opening 7 comes to cover.
  • the one on the inside End face of the first side channel compressor 12 lying inlet opening 6 is by a corresponding sealing surface 10 of the Impeller housing of the second side channel compressor 14 and the on the side compressor 12 facing the first Front side of the second side channel compressor 14 lying Outlet opening through a corresponding sealing surface 10 of the Impeller housing of the first side channel compressor 12 is closed. So that are necessary for the series connection Flow connections by simply joining the two Compressor housing possible in the corresponding angular position. The additional inlet and outlet openings that are not required 6 and 7 are closed by means of corresponding covers 9.
  • the direct coupling of the corresponding inputs and Outlet openings 6 and 7 of the two impeller housings is thereby allows the connector block 5 of each impeller housing in terms of its axial width at least up to extends the two side planes (parting planes) of the impeller housing.
  • the terminal blocks 5 come from two that can be joined together Impeller housings directly in contact, so that with the interposition of a sealing element a direct one Connection of the respective openings 6 and 7 is possible.
  • FIGS. 3 and 4 only differ due to a different connection position of the with the outlet opening 7 of the second side channel compressor 14 connected Pipe piece 8. Of course, this can also be done with the inlet opening 6 connected pipe section 8 to the in the axial direction lying inlet opening 6 of the first side channel compressor 12 can be connected.
  • 5 to 7 show circuit variants for a flow independent operation of several side channels compressor 2.
  • the side channel compressor 2 pipes to be connected the corresponding inlet and outlet openings 6 and 7 of the individual side channel compressors 2 occupied.
  • more than two side channel compressors 2 can also be connected in series.
  • the next side channel compressor 2 is connected to the previous side channel compressor 2 rotated by the corresponding angle.
  • both a series connection of compressors and, at the same time, independent or parallel operation of the other compressors can be provided.
  • the inlet and outlet openings 6 and 7 provided on the circumference of the impeller housing enable the individual compressors to operate in a flow-independent manner in units consisting of more than two side channel compressors. Because the inlet and outlet openings are independently accessible.
