Definitions

  • the invention relates to a side channel ring compressor, in which the impeller hub is provided with blade rings, to which ring channels are assigned in the housing, and in which a divided middle body is provided between the blade rings.
  • This preamble refers to an arrangement as is known for example from DE-PS 872 819.
  • Ring compressors are already known in which two double-flow impellers are arranged on a shaft. This construction sometimes has assembly problems because the individual impellers must be precisely adjusted with respect to the gaps.
  • the object of the present invention is to design a compressor of the type mentioned in such a way that an arrangement with at least four active ring channels results in a simple manner.
  • the central body is additionally provided with ring channels which are assigned to the blade sides of the blade rings facing the central body.
  • a ring compressor with four active ring channels is obtained, which is relatively easy to disassemble and assemble and in which the problems of gap adjustment are not particularly difficult.
  • the present invention is not limited to the use of two vane wheels on a hub, but further vane rings can also be arranged on the same hub.
  • the blade rings can be arranged symmetrically with respect to the hub or on only one side of the hub. In the latter case, the blade rings and the associated housing can cover the electric motor used to drive the ring compressor in a pot-like manner. In a further development of this idea, it is advantageous if the drive motor is designed directly as an external rotor motor and carries the blade rings.
  • the individual ring channels can be well separated from one another and pressure stages that are largely independent of one another can thus be formed.
  • a hub 2 is fastened on a shaft 1 and has two double-flow vane rings 3 and 4 on its outer circumference.
  • the blade rings 3 and 4 are surrounded by a fixed housing 5.
  • the ring channel 51 of the housing 5 is assigned to the left half 32 of the blade ring 3 and the ring gap 52 to the right half 42 of the blade ring 4.
  • the flow in these ring channels 61 and 62 is generated by the active impeller halves 31 and 41 of the blade rings 3 and 4.
  • Figure 2 shows an extension of the basic idea shown in Figure 1, namely that in addition to the blade rings 3 and 4, other blade rings, e.g. Wreath 7 may be provided, the ring channels 53 are formed by corresponding recesses in the divided housing and a further center piece.
  • Figure 3 shows a modification in such a way that the two double-flow vane rings 3 and 4 are arranged on one side of the hub 2 and cover the motor 11 used for driving the pot like a pot.
  • the center body 6 is provided with either a circumferential projection 63 or a circumferential recess 64, which are then encompassed by the recesses 33 in the blade rings 3 or as circumferential ones Extend extension 43 of blade ring 4 into recess 64.
  • each impeller for example 9 has four blade parts 91, 92, 93 and 94 which work together with an annular gap If you do not want to reach for a split housing, an additional split center body 10 must be provided here in addition to the center body 6.
