Description
Dampfstrahlpumpe. Den Gegenstand vorliegender Erfindung bildet eine Vorrichtung zur Förderung von Flüssigkeiten in einem scheibenförmigen Hohlgefäß mittels Dampfstrahlen, die derart auf die Flüssigkeit einwirken, daß eine rasch kreisende Bewegung derselben um die Mittelachse des Gefäßes entsteht, wobei sowohl die Drehgeschwindigkeit der Flüssigkeitsteilchen wie auch deren Pressung infolge der Fliehkraftwirkung nach dem Umfang zu eine wesentliche Steigerung erfährt.Steam jet pump. The subject of the present invention is one Device for conveying liquids in a disc-shaped hollow vessel by means of steam jets, which act on the liquid in such a way that a rapidly circular movement of the same around the central axis of the vessel, whereby both the speed of rotation of the liquid particles as well as their pressure as a result the centrifugal effect undergoes a substantial increase according to the scope.
Um eine günstige Wirkung zu erzielen, ist es notwendig, daß die kreisende Flüssigkeit von der Drehachse aus sich scheibenförmig ausbreitet und daß auf die Flüssigkeitsscheibe eine Anzahl um die Drehachse gruppierter, in Richtung des Umfanges unter spitzem Winkel zu den Scheibenflächen geneigter Treibmittelstrahlen einwirkt, wodurch die gewünschte kreisende Bewegung der Flüssigkeit entsteht. Am äußeren Umfang der kreisenden Flüssigkeit, wo die Geschwindigkeit der Flüssigkeitsteilchen und der Fliehkraftdruck am größten sind, wird die Flüssigkeit von einer nach Art der Kreiselpumpen ausgebildeten Leitvorrichtung aufgenommen und die erreichte Höchstgeschwindigkeit in bekannter Weise in Druckhöhe umgesetzt. Die Summe aus Fliehkraftdruckhöhe und Geschwindigkeitshöhe ergibt die gesamte zu überwindende Druckhöhe.In order to achieve a beneficial effect, it is necessary that the circular Liquid spreads out from the axis of rotation in the form of a disk and that on the A number of liquid discs grouped around the axis of rotation, in the direction of the circumference propellant jets inclined at an acute angle to the disc surfaces acts, which creates the desired circular movement of the liquid. On the outer circumference the circulating liquid, where the velocity of the liquid particles and the centrifugal pressure are greatest, the fluid is of a kind of Centrifugal pumps trained guide device added and the maximum speed achieved implemented in a known manner in pressure height. The sum of the centrifugal pressure height and Velocity altitude gives the total pressure altitude to be overcome.
In den Fig. r bis 3 ist eine derartige Vorrichtung in verschiedenen Schnitten dargestellt. Die Flüssigkeit, beispielsweise Wasser, tritt bei a (Fig.x) in die Vorrichtung ein und breitet sich in dem durch die Wände c, d gebildeten scheibenförmigen Raum e aus. Der dem Raum f zugeführte Frischdampf gelangt durch die in der Scheibenwand c vorgesehenen, spitz zu den jeweiligen Strombahnen liegenden düsenförmigen Üffnungen g in die Wasserscheibe e und setzt diese nach Maßgabe der Dampfenergie in rasch kreisende Bewegung. Fig. 2 zeigt einen zylindrischen, in die Zeichenebene abgewickelten Schnitt durch den Scheibenraum und dessen Begrenzungswände c und d. Die schräg liegenden, zylindrischen oder konischen oder sonstwie ausgebildeten Kanäle führen den Dampf in das Wasser und beschleunigen dieses in der Pfeilrichtung von Fig. 3, d. i. annähernd in Richtung der Tangenten an die Kreisbahnen. Fig. 3 zeigt die beliebig entsprechend den besonderen Umständen um die Drehachse gruppierten Dampfdüsenöffnungen g der scheibenförmigen Begrenzungswand c.Such a device is shown in different sections in FIGS. The liquid, for example water, enters the device at a (FIG. X) and spreads in the disk-shaped space e formed by the walls c, d. The live steam supplied to the space f passes through the nozzle-shaped openings g provided in the disk wall c and pointed to the respective flow paths into the water disk e and sets it in rapid circular motion in accordance with the steam energy. FIG. 2 shows a cylindrical section, developed in the plane of the drawing, through the disk space and its boundary walls c and d. The inclined, cylindrical or conical or otherwise designed channels lead the steam into the water and accelerate it in the direction of the arrow in FIG. 3, ie approximately in the direction of the tangents to the circular paths. 3 shows the steam nozzle openings g of the disk-shaped delimiting wall c, which are grouped around the axis of rotation in any way according to the particular circumstances.
Das die kreisende Flüssigkeit umschließende Gehäuse h kann. in ähnlicher Weise wie das Spiralgehäuse von Kreiselpumpen ausgebildet werden, wodurch die annähernd tangential gerichtete Austrittsgeschwindigkeit des Wassers aus dem Scheibenraum mit gutem Wirkungsgrad in Druck umgesetzt wird.The housing enclosing the circulating liquid h can. in similar Way how the volute casing of centrifugal pumps are formed, whereby the approximate tangentially directed exit speed of the water from the disk space is converted into pressure with good efficiency.
