Definitions

  • the invention relates to a liquid ring pump according to the preamble of claim 1.
  • Such a liquid ring pump is known from EP-A-0 367 845.
  • a deflection member is arranged in the flow path from the outlet opening of the control body to the pressure port, through which the liquid contained in the liquid mixture of the liquid ring pump is deflected such that its direction of flow is directed transversely to the direction of flow of the gas contained in the liquid mixture. In this way, a liquid curtain is created that has a sound-absorbing effect.
  • the invention has for its object to design a liquid ring pump of the generic type so that the noise reduction in its outlet area is further improved.
  • the locking member can be designed as a flat cover part lying tightly against the peripheral edge of the mouth opening of the outlet. Such a part is particularly simple to manufacture.
  • a particularly simple embodiment of the liquid ring pump results from the fact that the locking member is designed in the manner of a film and consists of an elastic material and that in the region of the mouth opening of the outlet by means of a separating cut in the locking member at least one elastic that can be expanded by the conveyed medium Tongue is formed.
  • a relatively large cross-section and a favorable flow shape of the passage opening are made possible by two intersecting separating cuts on the locking member.
  • the liquid ring pump 1 denotes a liquid ring pump flanged to the housing of a drive motor 2.
  • the liquid ring pump 1 has a pump housing 4 which receives the impeller 3 of the pump and which is provided on one side with a smooth end flange 5.
  • a control disk 7 is arranged as a control body between a housing cover 6 and the pump housing 4.
  • On the housing cover 6 there is an intake port 8 and a pressure port 9, which ports each in a suction chamber 10 formed in the housing cover 6 or in one with the pressure chamber 11 open via a mouth opening 15 communicating outlet 9 '.
  • On the control disc 7 there is the inlet opening 12 and the outlet opening 13 of the liquid ring pump. These openings 12 and 13 are arranged on the control disk 7 so that the inlet opening 12 is in communication with the suction chamber 10 and the outlet opening 13 with the pressure chamber 11 of the housing cover 6.
  • a foil-like blocking member 14 is inserted into the pressure chamber 11, which completely covers the opening 15 of the outlet 9 'into the pressure chamber 11.
  • This locking member 14 can be designed so that it also covers the side walls of the pressure chamber 11. As a result, the sealing effect of the locking member 14 is improved.
  • two intersecting separating cuts 16 are made. These triangular cuts 16 form four triangular tongues 17.
  • the tongues 17 spread, as indicated by dashed lines in FIG.1. This creates a passage opening 18, the cross section of which is set such that the passage opening 18 is completely filled by the medium flowing through. This means that there is no clear path for the passage of noise, so that good noise reduction is achieved.
  • This noise reduction is above 10 dB in particular at high suction pressures of the liquid ring pump.

Claims (4)

  1. Pompe à anneau liquide, comportant un rotor (3) tourillonné de manière à pouvoir tourner dans le carter (4) de cette pompe, un corps de commande (7), qui possède une ouverture d'admission et une ouverture de sortie (12 et 13) et dont l'ouverture de sortie (13) débouche dans une chambre de pression (11) prévue dans le carter de la pompe et qui est reliée à une sortie (9') par l'intermédiaire d'une ouverture d'embouchure (15), caractérisée par le fait que dans la chambre de pression (11) est disposé, sur le trajet d'écoulement entre l'embouchure de l'ouverture de sortie (13) et l'ouverture d'embouchure (15) de la sortie (9'), un organe de blocage (14), qui ferme l'ouverture d'embouchure (15) de la sortie (9') et qui possède une ouverture de passage (18), dont la section transversale de passage peut être adaptée automatiquement à la quantité du fluide entraîné par la pompe.
  2. Pompe à anneau liquide suivant la revendication 1, caractérisée par le fait que l'organe de blocage (7) est réalisé sous la forme d'une partie de fermeture plane, qui s'applique d'une manière étanche contre le bord périphérique de l'ouverture d'embouchure (15) de la sortie (9').
  3. Pompe à anneau liquide suivant la revendication 1 ou 2, caractérisée par le fait que l'organe de blocage (14) est réalisé sous la forme d'une feuille et est formé d'un matériau élastique, et qu'au moins une languette élastique (17), qui peut être écartée par le fluide entraîné, est formée par une section de séparation (16) dans l'organe de blocage (14).
  4. Pompe à anneau liquide suivant la revendication 3, caractérisée par le fait que deux sections de séparation croisées (16) sont prévues dans l'organe de blocage (14).
