Definitions

  • the invention relates to a multi-stage side channel pump for compression compressible media, whose impellers are coupled to a common drive shaft are, the geometry of each stage by dimensioning its impeller diameter and its flood diameter to the specific volume of the Medium is adapted to their inlet.
  • the impellers are of several stages, usually two stages, usually side by side on a common drive shaft attached. Only those types of construction are known in which the impellers of two adjacent levels have the same geometry and size.
  • the inlet the subsequent stages are usually immediate within a common housing connected to the outlet of the previous stage.
  • a compressor arrangement is already known from DE-GM 7 441 311, at. of several impellers of different widths on a common drive shaft are arranged side by side.
  • the associated impellers should each operated individually, connected in parallel or combined in series become.
  • a multi-stage side channel pump is known from FR-A-2 294 114, whose impellers are coupled to a common drive shaft.
  • the vote the conveying data of the individual stages can be determined by different impeller widths, different blade numbers or blade shapes and impeller diameters be made.
  • the invention makes a multi-stage side channel pump available provided that is particularly variable in terms of their design.
  • the impellers of the two stages of an assembly each are attached to a common shaft section.
  • a common one Shaft section of an assembly is via a coupling to the drive shaft coupled and the common shaft sections of the modules are coupled with each other by a coupling.
  • each stage is dimensioned smaller overall as the previous stage. Because the wheels of both stages with rotating at the same speed results for the next stage the same pressure difference between inlet and outlet as for the preceding stage.
  • volume ratio V 2 V 1 0.829, where the value 1.4 (diatomic gas) is used for the adiabatic exponent K.
  • stages are preferably strung together in a modular design.
  • Two stages are in one housing to one Assembly summarized, wherein the wheels on a common shaft section are attached; the housing one of. Assemblies is attached to the common drive unit and another assembly in turn to this one assembly flanged, the shaft sections of the assemblies with each other or with the drive shaft of the Drive unit are coupled by a clutch.
  • Another advantageous embodiment of the invention exists in that the inlets and outlets of the stages are separated are brought out. This way the levels freely combined with each other or separately operate.
  • a multi-stage side channel pump are a drive motor 10, a first stage 12 and a second stage 14 in one Integrated unit.
  • One of the two stages 12, 14 common housing 16 is built on a base 18.
  • the wheels 20, 22 of the two stages 12, 14 are on one common drive shaft 24 attached directly to the rotor of the drive motor 10 is connected.
  • On the Side of the drive motor 10 is with the housing 16 screwed first housing cover 26, in which the side channel 28 of the first stage 12 is formed.
  • the housing 16 On the opposite side is with the housing 16 a second Screwed housing cover 30, in which the side channel 32 of the second stage 14 is formed.
  • Inlet and outlet of the second stage 14 are through channels in the housing 16 and in the first housing cover 26 led to a connecting plate 34, the separately with reference to Figures 5 to 12 is described. Furthermore, inlet and outlet are the multi-stage side channel pump through a silencer 36 guided.
  • the two stages 12, 14 are dimensioned differently.
  • the first stage 12 is the medium from entry to exit condensed so that the specific volume (reciprocal the density) decreases accordingly.
  • the medium is now taking over smaller volume.
  • the second stage 14 is downsized Volume adjusted.
  • the second stage 14 is the required final pressure divided equally between the two stages 12, 14 so that the Stage pressure of both stages is the same.
  • the volume ratio of the two stages 12, 14 from the relationship for derived the adiabatic as described at the beginning. With the The resulting volume ratio is then below the Assuming geometric similarity to the impeller geometry second stage calculated. This is particularly the case for the outside Impeller diameter D and the flood diameter d (FIG. 1) determinative.
  • Stages of the side channel pump their efficiency is optimized, because the size of each impeller is related to the volume of the Medium is adjusted.
  • connection plate 44 Since in the described embodiment, the inlets and outlets are brought out separately at the connection surface, can the two stages 12, 14 by designing the connection plate 44 combined in the desired manner become.
  • the two are Steps 12, 14 in the housing 16 with the housing covers 26, 30 and the impellers 20, 22 on a common shaft section 50 combined into one unit.
  • the housing cover 26 is on the drive motor 10 facing Surface formed as a flange and can with a correspondingly designed connecting flange on the drive motor 10 be screwed.
  • the shaft section is via a coupling 52 50 directly to the rotor of the drive motor 10 connected.
  • a fan 54 is connected to the shaft section 50.
  • the housing cover 30 is also with a connecting flange educated. This is the one shown in FIG Embodiment attached a housing part 56, the It is part of the load-bearing structure of the side channel pump.
  • each stage In the embodiment shown in Figures 3 and 4 the inlets and outlets of each stage are separately on the side led out. Inlet and outlet of each stage are on one lateral connection surface 58a, 58b. 58c and 58d, respectively accessible. On each of these pads 58a to 58d put on a connection plate; in Figure 4 are two of these Terminal plates 60a and 60b shown cut.
