Description
Pumpe mit umlaufendem Flüssigkeitsring zur Förderung von Gasen Die - sogenannten Wasserri.n9p-umpen zur Förderung von Gasen arbeiten bekanntlich in der Weisie, daß ein im Innern des Gehäuses umlaufender Wasserring abwechselnd sich dem Laufrad nähert und sich von diesem wieder entfernt -und daß dadurcheine Kolbenwirkung auf das iwischen den Flügeln des Laufrades befindliche Gas ausgeübt wird. Das Gas wird durch' Ansaugeschlitze angesaugt und durch Druckschlitze ausgestoßen. Infolge der Verdichtung des geförderten Gases tritt eine Erwärmung des Wasserringes ein, die ziemlich erheblich sein kann.Pump with rotating liquid ring for conveying gases, the - so-called Wasserri.n9p-ump for conveying gases work well known in the Weisie that a circumferential inside the housing water ring alternately approaches the impeller approaches and moves away -and- from this again thereby a piston effect the gas between the blades of the impeller is exerted on it. The gas is sucked in through suction slots and expelled through pressure slots. As a result of the compression of the pumped gas, the water ring is heated, which can be quite considerable.
Man kann nun einer zu stark-en Erwärmung des Wass#erringes dadurch begegnen, daß man der Pumpe ständig frisches Wasser zuführt, wobei das überflüssige Wasser durch die Druckschlitze aus der Pumpe hinausbefördert wird. Es hat sich aber gezeigt, daß insbesondere bei Pumpen mit stark wechselnder Leistung auch die Erwärmung des Wasserringes so stark wechselt, daß man beispielsweise durch Änderung der Frischwasserzufuhr zur Pumpe von -Hand diesem Umstand nicht Rechnung tragen kann. Dies ist aber sehr nachteilig, weil bei stark erwärmtem, Wasserring eine verstärkte Dampfbildung eintritt, der Druck des Wasserdampfes erheblich ansteigt und dadurch die Leistung der Pumpe sehr beeinträchtigt wird.One can now cause the water ring to heat up too much encounter the fact that the pump is constantly supplied with fresh water, with the superfluous Water is pumped out of the pump through the pressure slots. But it has shown that, especially in pumps with greatly changing power, there is also a rise in temperature of the water ring changes so much that you can, for example, change the fresh water supply to pump by hand cannot take this into account. But this is very much disadvantageous because when the water ring is strongly heated, increased steam formation occurs, the pressure of the water vapor increases considerably and thereby the performance of the pump is very impaired.
Der Zufluß der Frischwassers oder gegebenenfalls einer anderen Betriebsflüssigkeit wird daher gemäß der Erfindung selbsttätig in Abhängigkeit von der Temperatur des in der Pumpe umlaufenden Flüssigkeitsringes oder des geförderten Gases geregelt. Dies kann beispielsweise in an sich bekannt-er Weise dadurch erfolgen, daß eine im Zuführungsrohr angeordnete Ab » schlußvorrichtung für die Betriebsflüssigkeit in Abhängigkeit von dev# Durchbie,guug eines Bimetallstreifens sel 'wk. tätig gesteuert wird.The inflow of fresh water or, if necessary, of another operating fluid is therefore automatically regulated according to the invention as a function of the temperature of the liquid ring circulating in the pump or of the conveyed gas. This can he done known-manner by, for example, in a manner that one is arranged in the feed tube from "circuiting device for the operating fluid in response to dev # Durchbie, guug a bimetallic strip sel 'wk. is actively controlled.
Die Einrichtung kann auch VerwendeW, finden, wenn. an Stelle von Wasser eine andere Flüssigkeit für die Bildung des Flüssigkeitsringes benutzt wird.The facility may also find use, if. instead of water another liquid is used for the formation of the liquid ring.
