Definitions

  • the invention relates to a liquid ring machine according to the preamble of the claim.
  • the arrangement of injection nozzles in the inlet area in front of the relevant side plate is known, in which, regardless of the liquid level in the side plate, a certain amount of operating liquid is always supplied, which is based on the requirements of keeping the amount of the rotating liquid ring constant with pure gas delivery, so that in the case of mixed gas-liquid delivery, the constant addition of operating liquid results in an additional enlargement of the rotating liquid ring, which causes a correspondingly higher load on the liquid ring machine.
  • the invention has for its object to automatically throttle the operating fluid supplied by the injection nozzles with a certain pressure from a quantity required for pure gas production to a smaller quantity with mixed coloring, so that with increasing liquid content in the medium to be pumped operating fluid is saved, the increase in Liquid ring throttled practically to zero and a reduced sensitivity of the machine (pump) can be achieved.
  • an increased condensation effect is aimed for in the case of operational moist air extraction.
  • control disks instead of the control disks, frustoconical control arrangements with suction and passage openings can also be provided.
  • the side plate 1 according to FIGS. 2 and 3 has at the top inlets and outlets 2, 3 and possibly additional side inlets and outlets 2 ', 3', which each open into the same inlet area 2A (or outlet area), the Arranged on both sides of the shaft opening 4 and covered by the covering control arrangements shown in FIG. 1 in the form of control disks 12 with a suction slot 10 and pressure slot 11 against the housing 13 with a rotating paddle wheel 14.
  • an injection nozzle 7 is arranged above the minimum liquid level 8 in the case of pure gas production in the side plate 1, but below the maximum liquid level 9 in the case of mixed gas-liquid production.
  • the liquid can be fed to the injection nozzle 7 without pressure (only by the suction power of the pump).
  • the operating liquid supplied at a specific pressure to the injection nozzle 7 for cooling the machine, sealing the gaps and supplementing the rotating liquid ring with pure gas delivery can be supplied in maximum amount in the form of a liquid curtain in front of the suction slit 10, on the other hand when conveying mixed medium in the covered state Depending on the liquid level, flow throttled into the liquid in the side plate without forming a liquid curtain.
