Definitions

  • the invention relates to a liquid ring compressor for gases according to the preamble of patent claim 1.
  • the position of the inner contour of the housing relative to the pressure outlet must be adjusted according to the respective desired pressure ratio.
  • the holes in the hole area which are in the final pressure area, allow the compressed gas to penetrate more easily from the front of the control disk facing the impeller wheel to the rear of the control disk than the holes further away from the final pressure area, since the liquid located on the rear side of the control disk increasingly seals the less pressurized holes on the other side, so that it is practical there is a kind of liquid valve effect.
  • the diameter of the bores must be adapted to the blade thickness and the ratio should not exceed 1.2: 1, a flow limit speed cannot be undercut, so that corresponding flow losses have to be accepted.
  • the said ratio of bore diameter to blade thickness is selected with regard to harmful backflows via bore to bore from the blade chamber to the blade chamber, since backflows that are too large nullify the possible efficiency improvement by decreasing the flow losses due to smaller flow resistances.
  • An increase in the number of bores spaced apart from one another in order to reduce the flow speed is neither possible in the radial extension nor in the circumferential direction, since in the former case the rotating liquid ring would be impaired and in the second case the pressure ratio would be reduced.
  • the invention has for its object to achieve a reduction in the required power consumption and improvement in efficiency for widely varying pressure ratios while eliminating the need for a housing adjustment.
  • the outlet cross sections are increased while the passage area remains the same and the flow velocities or flow losses are thus reduced. If necessary, the area can even be shortened to increase the pressure ratio without reducing the entire outflow cross section of the area and pressure slot (pressure outlet).
  • a noticeably increased intake volume flow increase on average about 10 s
  • a noticeably reduced power consumption on average about $ 15
  • the improvement effect can be intensified, ie a reduction in power consumption over 15 and an intake volume flow higher than 10 can be obtained.
  • the radial slots have a correspondingly curved contour.
  • At least one end-shield is equipped with inlet and outlet connections for the gas to be conveyed and compressed and a pressure fluid supply line, in front of which a flat circular control disk 1 according to FIGS. 1 and 2 is equipped with a Sickle-shaped "suction slit 2 and a crescent-shaped pressure slit 3, along with radial slits 3B arranged in the direction of rotation of the impeller, can be assigned to the other end plate with the same design, the same control disk or a simple circular disk with a bearing plate used exclusively for shaft support.
  • an arcuate region 3A in front of the pressure slot 3 there are a number of radial slots 3B of approximately the same length at a distance from one another, the slot width of which is adapted to the blade thickness of the blade wheel (not shown).
  • the slot length is dimensioned more than twice the slot width and is longer than the radially extending start of the suction slot 3.
  • the total extent of the pressure outlet 3 and 3B in the circumferential direction corresponds approximately to that of the suction slot 2.
  • FIG. 5 shows the comparable arrangement of radial slots 3B for a control disk with a circulating liquid bore 8 behind the suction slot 2.
