Definitions

  • the invention relates to a side channel ring compressor, in which the impeller hub is provided with at least two blade rings, to which active ring channels are assigned in the housing, and in which a divided middle body is provided between the blade rings.
  • This generic term 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 the introduction 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 at least two active ring channels which are assigned to the blade sides of the double-flow blade rings facing the central body.
  • the present invention is not limited to the use of two blade wheels on one hub, but further blade 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 channel 52 to the right half 42 of the blade ring 4.
  • FIG. 2 shows an extension of the basic idea shown in FIG. 1, and in addition to the blade rings 3 and 4, further blade rings, e.g. B. wreath 7 may be provided, the ring channels are formed by corresponding recesses of the divided housing and a further center piece 53.
  • Figure 3 shows a modification in such a way that the two double-flow blade 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 a circumferential extension 43 of the blade ring 4 engage in the recess 64.
  • the blade rings 8 and 9 are also divided in the radial direction, so that each impeller, for. B. 9, four blade parts 91, 92, 93 and 94, which cooperate 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.
