Definitions

  • the invention relates to a liquid ring pump according to the preamble of claim 1.
  • Such a liquid ring pump is known from DE-OS 34 21 866.
  • the deflection wall opposite the pressure slot is designed as a baffle for the gas-liquid mixture emerging from the pressure slot. Further sharp deflections of the mixture flow take place through wall parts arranged further above and behind the deflection wall. In the case of these deflections, the specifically heavier liquid particles are separated from the gas particles because the liquid particles strike the deflection wall and the other wall parts because of their greater inertia. The liquid particles then flow down into the two chambers formed by the deflection wall in the side plate.
  • the multiple deflection of the mixture flow requires, on the one hand, appropriately arranged wall parts which lead to a form of the side plate that is difficult to manufacture, and on the other hand, such sharp deflections also result in considerable flow losses and require a large overall length.
  • the invention has for its object to design a liquid ring pump according to the preamble of claim 1 so that an improved liquid separation is achieved with less flow losses by means of a side plate that is easier to manufacture.
  • the rotational movement of the gas-liquid mixture is improved in that the other side of the deflecting wall reaches close to the control disk while leaving a passage slot, or else in that the other side of the deflecting wall also abuts the control disk.
  • the liquid outlet can advantageously also be arranged in this center.
  • the inner tube thus serves to discharge the gas, whereas the liquid can drain through the shorter outer tube.
  • the two tubes are advantageously joined together concentrically.
  • the pump rotor 3 provided with rotor blades 2 is arranged eccentrically in the pump chamber 4 of the pump housing 5 with respect to the housing axis.
  • the pump chamber 4 is closed at least on one side by means of a control disk 7 provided with a suction and pressure slot 6a and 6b.
  • the control disk 7 is covered by a side plate 8 attached to the pump housing 5.
  • a suction chamber 10 and a pressure chamber 11 are known to be delimited from one another by a web 9.
  • an arc-shaped, preferably circular-shaped deflection wall 12 is provided, which divides the pressure chamber 11 into an inner and outer chamber 13 and 14.
  • the deflection wall 12 is designed such that it runs with its one side 15 onto the pressure slot 6b of the control disk and abuts the control disk 7 with the side edge 16 of this side 15. In this way, the deflection wall 12 has a course following the control disk 7 which is approximately parallel to the gas-liquid flow (arrow 17) leaving the pressure slot 6b in the axial direction.
  • the gas-liquid flow is set in rotation on its further path through the deflection wall 12. Due to the centrifugal forces that occur, the liquid particles are thrown out of the gas-liquid mixture against the deflection wall 12 and flow downwards there.
  • the gas particles move to a passage slot 20 existing between the end 18 of the other side 19 of the deflection wall 12 and the control disk 7 and pass through this into the outer chamber 14.
  • an outward pressure connection 23 for the gas and an outlet connection 24 for the liquid are also provided on the side plate of the liquid ring pump 1 shown in FIGS. 1 and 2. With 23 'and 24' other possible positions of the pressure and drain connector on the side plate 8 are indicated.
  • an upwardly closed inner chamber 13 is formed in the side plate 8 by the deflecting wall 12.
  • a double pipe consisting of inner and outer pipes 25 and 26 is arranged in the center, i.e. In the central axis of the circular arc-shaped deflection wall 12, a double pipe consisting of inner and outer pipes 25 and 26 is arranged.
  • the inner tube 25 projects beyond the outer tube 26 in the axial direction and forms the gas outlet.
  • the liquid separated from the gas-liquid mixture can flow off via the outer tube 26.
  • the level 27 of the liquid level in the side plate 8 is determined by the end of this outer tube 26. In the liquid ring pump shown in FIG. 1, this liquid level 27 is determined by the position of the drain connector 24 on the side plate 8. Via an opening 28 provided in the web 9 separating the suction and pressure chambers 10 and 11, the liquid which has separated out can be returned to the pump circuit.
  • the circular arc-shaped deflection wall 12 can be brought up to the control disk 7 with the end 18 of the other side 19, ie it can also rest against the control disk 7 with this end 18, as is indicated by dashed lines in FIG. 1. This eliminates the passage slot 20 and the outer chamber 14 become inoperative.
  • the space delimited by the deflection wall 12 can thus encompass the entire pressure side half of the side plate.
  • a drain connection leading out laterally from the side plate can also be provided, as shown in FIG. 1. It is also possible to combine the two types of drain.
