Abstract

A liquid ring gas pump which consists of a pump section (1) and a drive section (6) has operating, cooling and lubricating fluid fed to it from a point (12) in a chamber (11) remote from the shaft, which chamber is partially defined by rotating parts (4, 8). The creation of a rotating liquid ring which might impede the fluid feed is counteracted by a flow disturbance device (15) arranged in the chamber, which device may be designed as a fin or housing projection running longitudinally or radially. <IMAGE>

Description

Die Erfindung betrifft eine Flüssigkeitsringgaspumpe mit Spalt­ rohrmagnet- bzw. Spaltrohrmotorantrieb nach dem Oberbegriff des Patentanspruches 1.The invention relates to a liquid ring gas pump with a gap Rohrmagnet- or canned motor drive according to the preamble of Claim 1.

Bekanntermaßen benötigen Flüssigkeitsringgaspumpen zur Aufrecht­ erhaltung ihres Betriebes eine ständige Flüssigkeitszufuhr von außen, da mit dem von der Pumpe verdichtetem Gas auch stets eine bestimmte Flüssigkeitsmenge durch den Druckstutzen aus der Pumpe mit ausgestoßen wird. Außer zur Wiederauffüllung des Flüssigkeits­ ringes in der Pumpe dient die von außen zugeführte Flüssigkeit ebenfalls zur Kühlung der Pumpe. Ebenso wie die Pumpe benötigt aber auch der Spaltrohrantrieb zur Kühlung und zur Schmierung ggf. vorhandener Lager auch eine ständige Zufuhr von Flüssigkeit von außen, die zusammen mit der Betriebsflüssigkeit der Pumpe zuge­ führt werden kann bzw. normalerweise zugeführt wird.As is known, liquid ring gas pumps need to stand up maintenance of their operations a constant fluid supply of outside, because with the gas compressed by the pump always one certain amount of liquid through the pressure port from the pump is expelled with. Except to replenish the liquid The liquid supplied from the outside serves as a ring in the pump also for cooling the pump. Just as the pump needs but also the canned drive for cooling and lubrication if necessary existing stock also a constant supply of liquid from outside, which together with the operating fluid of the pump can be performed or is normally supplied.

Bei der gemeinsamen Zuführung der Flüssigkeit für die Pumpe und den Antrieb in den Raum zwischen Pumpe und Antrieb hat sich ge­ zeigt, daß bei bestimmten Betriebszuständen keine bzw. nicht mehr ausreichend Flüssigkeit aus diesem Raum in die Pumpe eintritt und somit eine einwandfreie Funktion der Pumpe nicht mehr gegeben ist. Ursache dafür ist, daß sich in dem Raum, in den die Flüssigkeit zugeführt wird, ein sehr stabiler Flüssigkeitsring aufbaut, der das Einströmen der Flüssigkeit aus diesem Raum in die Pumpe er­ schwert bzw. verhindert. Dieser Zustand tritt verstärkt dann auf, wenn an der Flüssigkeitsringgaspumpe nur geringe Druckdifferenzen zwischen Pumpenansaug- und Pumpendruckstutzen herrschen. When supplying the liquid for the pump and the drive in the space between the pump and drive has ge shows that in certain operating conditions no or no more sufficient liquid enters the pump from this room and the pump will no longer function properly. The reason for this is that there is space in the liquid is supplied, a very stable liquid ring builds up the inflow of liquid from this space into the pump sword or prevented. This condition occurs increasingly if there are only slight pressure differences at the liquid ring gas pump prevail between the pump suction and pump pressure ports.  

Um die geschilderten Nachteile zu beheben, wird erfindungsgemäß vorgeschlagen, in den Raum zwischen Flüssigkeitsringgaspumpe und Spaltrohrantrieb, in den die Flüssigkeit eingeführt wird, eine Strömungsstörvorrichtung anzuordnen, vorzugsweise in Form einer Rippe oder eines Gehäusevorsprunges. Dadurch wird verhindert, daß sich in diesem Raum ein stabiler umlaufender Flüssigkeitsring auf­ baut. Vielmehr wird hierdurch eine Turbulenz in diesem Raum her­ vorgerufen, die dafür sorgt, daß wieder ausreichend Flüssigkeit in die Flüssigkeitsringgaspumpe hineingelangt.In order to eliminate the disadvantages described, the invention proposed in the space between liquid ring gas pump and Canned tube drive into which the liquid is introduced, one Arrange flow disturbance device, preferably in the form of a Rib or a housing protrusion. This prevents a stable, circumferential liquid ring opens up in this room builds. Rather, this creates turbulence in this room called, which ensures that again sufficient fluid got into the liquid ring gas pump.

In Fortführung des Erfindungsgedankens wird weiter vorgeschlagen, daß die Strömungsstörvorrichtung in einer axparallel angeordneten Rippe bzw. einem axparallel angeordneten, in den Ringraum hinein­ ragenden, Gehäusevorsprung besteht. Durch die Axparallelität läßt sich eine optimale Störung des geordneten Flüssigkeitsringes und somit auch eine gute Durchwirbelung der Flüssigkeit in diesem Raum erreichen.In continuation of the inventive concept, it is further proposed that that the flow disturbance device is arranged in an axially parallel Rib or an axially parallel, into the annulus protruding, housing projection. Due to the parallelism of the ax there is an optimal disturbance of the ordered liquid ring and thus also a good swirling of the liquid in this room to reach.

Auf eine zeichnerische Darstellung der erfindungsgemäßen Ausfüh­ rung kann in diesem Falle wegen der Einfachheit verzichtet werden.On a graphic representation of the embodiment according to the invention In this case, it can be omitted because of the simplicity.
