Definitions

  • the invention relates to a liquid ring machine with an eccentrically arranged within a housing, rotating in engagement with a rotating liquid ring, the shaft of which is rotatably mounted in bearing plates arranged on both sides of the housing and at least one bearing plate as with inlets and outlets for the medium to be conveyed and with Connections for the liquid ring additionally supplied operating fluids is formed according to the preamble of claim 1.
  • Such a liquid ring machine is known from DE-AS 10 27 358, in which correspondingly heated partial liquid is drained from the rotating liquid ring behind the end of the pressure slot via an opening in the control disk and is supplied via a radial transverse groove to a shaft-concentric ring groove covered by the impeller hub, from which this partial liquid flows again radially over the entire circumference of the annular groove as a sealing gap liquid to the rotating liquid ring.
  • a second, colder portion of the operating fluid which replaces the fluid ring losses, is supplied to the fluid ring from the outside at a lower pressure via an opening not covered by the impeller hub between the end of the suction slot and the beginning of the pressure slot, for example from a fluid separator arranged downstream of the outlet of the control plate.
  • the amount of operating fluid flowing into the rotating liquid ring is warmer than the coolest partial liquid, which worsens the condensation effect in the case of moisture or water vapor extraction and increases evaporation when conveying dry air.
  • the invention has for its object to improve the condensation effect in liquid ring machines, in particular in pumps of the type mentioned, to reduce the evaporation when conveying dry air and thus to increase the pumping speed of the machine.
  • a known double-flow liquid ring machine is shown in an exploded view, in which the mixture of warmer and colder operating liquid portions takes place in the respective side plate 1 and the mixture of both through the passage 2 in the respective control disc 3 in the gap between the control disc 3 and paddle wheel 4th flows.
  • control disk is designed according to an exemplary embodiment, which is shown in FIG. 2 as a top view of the inside facing the paddle wheel and in FIG. 3 as a section along the line III-III of FIG. 2.
  • a partial annular groove 8 is provided, which is connected to at least one opening 9, 9 ⁇ and this opening 9 opens into a separate chamber in the side plate, which chamber is connected only to a coolant inlet to the a fresh water line or a liquid separator is connected via a recooler behind the outlet grooves in the side plate.
  • the partial ring groove 8 extends at least over the entire area of the suction slot 5 and can be led out of the impeller hub area at one end 8A behind the end of the suction slot. Furthermore, the partial ring groove can be extended beyond the beginning of the suction slot and optionally, as shown in broken lines, can be guided out of the paddle wheel hub area and connected there with an opening 9 ⁇ réelle.
  • the one or more openings 9, 9 ⁇ , 9 ⁇ can advantageously be provided at said end 8A of the partial annular groove 8, so that a cold, evenly distributed cold fissure liquid portion flows over the entire suction slot 5 in the direction of the paddle wheel rotation and optimizes the condensation effect.
  • a separate ring groove 10, 10 ⁇ is provided, which is at least least from the beginning of the pressure slot 6 to at most before the end of the same, in particular up to controllable partial areas and with at least one opening 11, 11 ⁇ is connected, which opens into a separate chamber in the side plate, a separator or the rotating liquid ring, through which in known Way warmer liquid flows into the liquid ring, so that from this chamber via the opening 11 and the partial ring groove 10, 10 ⁇ the gap sealing liquids are returned to the liquid ring.
  • the opening 11 is covered by the impeller hub and can be connected to a recess 11A which extends radially outward beyond the impeller hub.
