Description
Umlaufpurnpe für Gasförderung Die Erfindung betrifit eine Umlaufpumpe, bei der in einem Gehäuse ein Laufrad mit seitlichen, ringförrnigen Schaufelräumen umläuft und bei der im Gehäuse Seitenkanäle mit Unterbreclier #,-o#rliaii"leii sind, in denen in bekannter Wei,#c- durch schraubenförmige Wirbelung eine druckerhöliende 'Wirkung für das zu fördernde Mediu:m eintritt. Die Um-]aufpumpe, auf die sieh die Erfindung be- zieht -. ist für reine Gasförderung bestimmt, d.Ii. sie fördert Luft oder andere Gase, ohne daß ein Flüssigkeitsring im Gehäuse VOTO'e_ sehen ist.Circulating pump for gas delivery The invention relates to a circulating pump in which an impeller with lateral, ring-shaped blade spaces revolves in a housing and in which the housing has side channels with subrecliers #, - o # rliaii "leii, in which in the known Wei, # c- through helical turbulence for the pumped Mediu a druckerhöliende 'effect: m enters the environmental] aufpumpe, to which the invention see loading draws - is designed for pure gas production, D.II. it promotes air or other gases without.. a liquid ring can be seen in the housing VOTO'e_.
Bei derartigen Pumpen ist eine gute Abdichtun '-, insbesondere am äußeren Umfang, des Laufrades von großer Bedeutung. Man 'hat bereits Labvrintlidichtungen zur Abdichtung von Laufrädern gegenüber dem Gehäuse angewandt. Gemäß der Erfindun- wird tiun am äußeren Umfang des Laufrades eine Labyrinthdichtung vorgesehen, die in besonderer Weise ausgebildet ist. Die Labyrinthdichtung besteht aus mehreren in das Laufrad eingedrehten Nuten, die gemäß der Erfindung ., derart schraubenfürmig verlaufen, daß bei Wassereintritt von, der Mitte des Laufrades her das Wasser durcli diese Nuten beiderseits nach außen fließt und die dichtende Wirkung erhöht.In such pumps, good sealing of the impeller, especially on the outer circumference, is of great importance. Labvrintlideals have already been used to seal impellers from the housing. According to the invention, a labyrinth seal, which is designed in a special way, is provided on the outer circumference of the impeller. The labyrinth seal consists of several grooves screwed into the impeller, which, according to the invention, run helically so that when water enters from the center of the impeller, the water flows outward through these grooves on both sides and increases the sealing effect.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. i ist die Welle des Laufrades, 3 das im vorliegenden Beispiel aus zwei Teilen bestehende Laufrad. 4, 5, 6 und 7 sind vier ringförirrige Schaufelräume. auf jeder Seite des Laufrades, die alle entweder hintereinandergeschaltet oder g -r uppenweise parallel e geschaltet sein können.An exemplary embodiment of the invention is shown in the drawing. i is the shaft of the impeller, 3 the impeller consisting of two parts in the present example. 4, 5, 6 and 7 are four annular vane spaces. on each side of the impeller, all of which can either be connected in series or in groups in parallel.
Durch den Zwischenraum 8' hindurch wird Kühlwasser zwischen den beiden Radhälften nach außen geschleudert und im Rinigkanal 12 ge.sammel t. 13 sind die gemäß der Erfindung in das Laulfrad eingedrebten Nut,eii, die als Labyrintlidichtung dienen.Cooling water is thrown outwards between the two wheel halves through the space 8 'and is collected in the Rinigkanal 12. 13 are the groove, eii drilled into the Laulfrad according to the invention, which serve as a labyrinth seal.
Da die Nuten von der Mitte aus intch beiden Seiten schraubenföriiiig verlaufen. iließt aus dem Kanal 12 hinaus Diclitu-ngsflüssi-keit in. die Labyrintligänge liiii-eiii und nach beiden Seiten in den Nuten entlang, st) daß eine vorzügliclie Abdielitun#g-; des Laufrades bewirkt wird.Since the grooves are screw-shaped from the middle on both sides get lost. Diclitu-ngsliquid flows out of the channel 12 into the length of the labyrinth liiii-eiii and along both sides in the grooves, st) that an excellent Abdielitun # g-; of the impeller is effected.
. Natürlich kann die Dichtungsflüssigkeit auch auf andere Weise der Labyrintlidirlitung zugefülirt #werden. . Of course, the sealing liquid can also be added to the labyrinth lid line in other ways.
