Description

Erfindung: Strahlpumpe 1. I3eschreibung der Erfindung Die Erfindung bezieht sich auf eine Strahlpumpe mit rundem Querschnitt. Mehrere Treibdiisen sind an einer Ringleitung angeschlossen, so daß ihre zündungen parallel der Wandung des anschließenden Schlepprohres gerichtet sind.Invention: Jet Pump 1. Description of the Invention The invention refers to a jet pump with a round cross-section. There are several driving channels connected to a ring main, so that their ignitions are parallel to the wall of the subsequent tow pipe are directed.

Aufgabe der Erfindung ist es, eine Strahlpumpe zu schaffen, die mit konstruktiven Mitteln die Strömungsverluste ver -ringert, um damit den Wirkungsgrad entscheidend zu verbessern.The object of the invention is to create a jet pump that with constructive means reduce the flow losses, thereby increasing the efficiency to improve decisively.

Die Aufgabe wird dadurch gelöst, daß die Treibdüsen an einer Itingleitung angeschlossen sind und deren Treibstrahl parallel zu der Wandung des Treibrohres gerichtet ist. Die freibdüsen sind konstruktionsmäßig nach den bekannten Gesetzmäßigkeiten ausgeführt, so daß die Energieverluste gering gehalten werden. Durch die Anordnung der Treibdüsen bilden die Treibstrahlen zwischen dem Fördermedium und der Rohrwandung eine reibungsvermindernde Schicht, die sich außerordentlich günstig auf den Wirkungsgrad auswirkt. Die Yerwirbelungen in der Fangdüse des herkömmlichen Strahlapparates treten hier nicht auf, vielmehr übt das Treibmediumeine Schleppfunktion aus, die eine bessere Energieausnutzung zur Folge hat.The object is achieved in that the propulsion nozzles on an iting line are connected and their propulsion jet parallel to the wall of the propulsion pipe is directed. The free jets are designed according to the known principles executed so that the energy losses are kept low. By the arrangement of the propulsion nozzles form the propulsion jets between the conveying medium and the pipe wall a friction-reducing layer, which has an extremely beneficial effect on efficiency affects. The turbulence in the catching nozzle of the conventional jet device occurs not up here, rather the propellant has a dragging function, which is a better one Energy utilization has the consequence.

An 1iand der Zeichnung wird die Erfindung näher erläutert.The invention is explained in more detail on the basis of the drawing.

Die Zeichnung bindet ab: a) Einen axialen Halbschnitt parallel zur Strömungsrichtung b) Einen vertikalen llaltvschrlitt A-U senkrecht zur Ströungsrichtung.The drawing binds: a) An axial half-section parallel to the Direction of flow b) A vertical step A-U perpendicular to the direction of flow.

Der Strahlapparat besteht aus drei Hauptteilen. Dem Binführungsrohr 1, tinern Zwischenstück 2 mit den Treibdüsen 2a sowie einem Schlepprohr 3. Die Treibdüsen 2a sind mit (iewinde versehen und werden in das Zwischenstück hineingedreh. Die Treibdüsen sind so gerichtet, daß ihre Treibstrahlen parallel der Wandung des Schlepprohres gerichtet sind. Das Einführungsrohr 1 ist in Strömungsrichtung so angeschrägt, daß eine verlustarme Angleichung des'Fördermediums an Treibmedium erfolgen kann. Die Abdichtung erfolgt mit den 0- Ringen la. ei der gezeigten Ausführung ist eine äußerst einfache Montage der Feile 1-3 zu erken-' neun. Mit Hilfe der Innensechskanntschrauben 4 und 5 kann die Montage scbnell und rationell erfolgen.The jet apparatus consists of three main parts. The guide tube 1, tinern intermediate piece 2 with the propulsion nozzles 2a as well as a tow pipe 3. The propulsion nozzles 2a are provided with (iewinder) and are inserted into the intermediate piece screwed in. The propulsion nozzles are directed so that their propulsion jets are parallel the wall of the tow tube are directed. The introduction tube 1 is in the direction of flow beveled so that a low-loss adjustment of the conveying medium to the driving medium can be done. The seal is made with the 0-rings la. ei the execution shown an extremely simple assembly of the file 1-3 can be seen. With the help of the Allen screws 4 and 5, assembly can be carried out quickly and efficiently.

Die Strahlpumpe ist speziell mit Druckluft als Treib- und Flüssigkeiten als Fördermedium einsetzbar.The jet pump is specially designed with compressed air as the propellant and liquids can be used as a conveying medium.

Patentanspruch Claim Die Erfindung bezieht sich auf den gesamten Strahlapparat wie beschrieben und gekennzeichnet.The invention relates to the entire jet apparatus as described and marked. Die Erfindung ist dadurch gekennzeichnet, daß an einer Ringleitung mehrer Düsen angeschlossen sind und deren Treibstrahlen parallel der anschließenden Wandung des Schlepprohrers verlaufen und damit das Fördermedium ansaugen. Durch die Grenzschichtbeblasung tritt eine reibungsvermindernde Schicht ein, die einen besonderen Wirkungsgrad zur Folge hat.The invention is characterized in that on a ring line several nozzles are connected and their propulsion jets parallel to the subsequent one The wall of the tow pipe and thus suck in the pumped medium. By the boundary layer blowing occurs a friction-reducing layer, the one results in a special degree of efficiency. Weiterhin ist die Erfindung dadurch gekennzeichnet, daß sie sehr einfach zu montieren und prohlemlos in Rohrleitungen eingebaut werden kann.Furthermore, the invention is characterized in that it is very simple to assemble and can be installed in pipelines without any problems.
