Description

Beschreibungdescription
Mischrohr einer SaugstrahlpumpeMixing tube of a suction jet pump
Gegenstand der Erfindung ist ein Mischrohr einer Saugstrahlpumpe mit einem Einlassbereich, einem Mischbereich und einem Auslassende, über das das zu fördernde Medium das Mischrohr verlässt. Saugstrahlpumpen finden Verwendung zur Kraftstoffförderung in Kraftstoffbehältern.The invention relates to a mixing tube of a suction jet pump having an inlet region, a mixing region and an outlet end, via which the medium to be delivered leaves the mixing tube. Suction jet pumps are used for fuel delivery in fuel tanks.
Derartige Mischrohre sind Bestandteil von Saugstrahlpumpen, in denen sie in axialer Ausrichtung zu einer Treibdüse eingesetzt sind. Ein über eine Treibmittelleitung der Treibdüse zugeführtes Treibmittel tritt unter hohem Druck aus der Treibdüse aus und in den Einlassbereich des Mischrohres ein. Aufgrund der Geschwindigkeit des Treibmittelstrahls wird zwi¬ schen Treibdüse und Mischrohr ein Unterdruck erzeugt, der zum Ansaugen des zu fördernden Mediums in das Mischrohr genutzt wird. Über das Auslassende treten das Treibmittel und das zu fördernde Medium aus der Saugstrahlpumpe aus. Um das zu för¬ dernde Medium an den gewünschten Ort zu transportieren, ist das Auslassende mit einer Leitung oder einem Leitungsab¬ schnitt verbunden. Zum Verbinden des Leitungsabschnitts mit dem Auslassende des Mischrohres wird der Leitungsabschnitt auf das Auslassende aufgeschoben, wobei das Auslassende amSuch mixing tubes are part of Saugstrahlpumpen in which they are used in axial alignment with a motive nozzle. A propellant supplied via a propellant conduit of the motive nozzle exits the motive nozzle under high pressure and into the inlet region of the mixing tube. Due to the speed of the propellant jet Zvi ¬'s driving nozzle and the mixing tube is used the medium to be delivered into the mixing pipe for sucking is generated a negative pressure. About the outlet end of the propellant and the medium to be pumped out of the suction jet pump. To transport the to för ¬-promoting medium to the desired location, the outlet end to a conduit or a Leitungsab ¬ cut is connected. To connect the conduit section to the outlet end of the mixing tube, the conduit section is slid onto the outlet end with the outlet end at the outlet end
Außenumfang einer Verbindungsgeometrie, vorzugsweise ein Tan¬ nenbaumprofil, aufweist, um ein unbeabsichtigtes Lösen des Leitungsabschnitts vom Auslassende zu verhindern. Nachteilig ist der Montageschritt zum Verbinden des Leitungsabschnitts mit dem Auslassende. Neben dem zeitlichen Aufwand sind auch relativ hohe Montagekräfte notwendig, um einen sicheren Sitz des Leitungsendes auf dem Auslassende ohne zusätzliche Siche¬ rungsmittel, zum Beispiel Schlauchklemmen, zu gewährleisten.Outer circumference of a connection geometry, preferably a Tan ¬ nenbaumprofil, in order to prevent inadvertent release of the line section from the outlet end. A disadvantage is the assembly step for connecting the line section to the outlet end. In addition to the time required and relatively high assembly forces are necessary to ensure a secure fit of the line end on the outlet end without additional Siche ¬ means, such as hose clamps.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Mischrohr einer Saugstrahlpumpe zu schaffen, welches eine einfachere Montage zu geringen Kosten ermöglicht. Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass sich an das Auslassende ein Leitungsabschnitt anschließt und dass der Leitungsabschnitt einteilig mit dem Auslassende des Mischroh¬ res verbunden ist.The invention is therefore an object of the invention to provide a mixing tube of a suction jet pump, which allows easier installation at low cost. According to the invention the object is achieved in that adjoins the outlet end of a line section and that the line section is integrally connected to the outlet end of Mischroh ¬ res.
Mit der einteiligen Ausbildung des Auslassendes des Mischrohres und einem Leitungsabschnitt entfällt die nachträgliche Montage der Leitungen mit dem Mischrohr einer Saugstrahlpumpe. Verbindungsgeometrien am Auslassende des Mischrohres und an dem Leitungsabschnitt sind aufgrund der einteiligen Aus¬ führung nicht erforderlich. Damit verringern sich die Herstellkosten im erheblichen Maße, da sich zum einem der Materialeinsatz verringert und zum anderen entfallen die Spritzgusswerkzeuge, wenn die Mischrohrgeometrie in dem Werkzeug für den Leitungsabschnitt enthalten ist.With the one-piece design of the outlet end of the mixing tube and a line section eliminates the subsequent assembly of the lines to the mixing tube of a suction jet pump. Connection geometries at the outlet of the mixing tube and the lead portion are due to the one-piece from ¬ not leadership required. This reduces the production costs to a considerable extent, since on the one hand the use of material is reduced and on the other hand the injection molding tools are dispensed with if the mixing tube geometry is contained in the tool for the line section.
In einer vorteilhaften Ausgestaltung ist der Leitungsabschnitt als Wellrohr ausgebildet . Dies ist insbesondere dann von Vorteil, wenn die sich an die Saugstrahlpumpe anschlie- ßende Leitung mit kleinen Biegeradien verlegt werden muss.In an advantageous embodiment, the line section is formed as a corrugated pipe. This is particularly advantageous when the line connecting to the suction jet pump has to be laid with small bending radii.
Ein guter Übergang zwischen dem Auslassende des Mischrohres und der sich anschließenden Leitungen wird in einer anderen Ausgestaltung mit einem als Glattrohr ausgebildeten Leitungs- abschnitt erreicht.A good transition between the outlet end of the mixing tube and the subsequent lines is achieved in another embodiment with a trained as a smooth tube line section.
Die Fertigung des Mischrohres und des Leitungsabschnitts ist besonders kostengünstig, wenn das Auslassende und der Lei¬ tungsabschnitt aus demselben Werkstoff, beispielsweise Polyo- xymetylen (POM) oder Polyamid (PA) bestehen.The production of the mixing tube and the line section is particularly cost-effective if the outlet end and the Lei ¬ tion section of the same material, such as polyoxymetylene (POM) or polyamide (PA) exist.
In Abhängigkeit der Anforderungen an die sich an die Saugstrahlpumpe anschließende Leitung kann es vorteilhaft sein, wenn das Auslassende des Mischrohres und der Leitungsab- schnitt aus unterschiedlichen Werkstoffen bestehen. Ein derart gestaltetes Mischrohr mit einem Leitungsabschnitt lässt sich im Zwei-Komponenten-Spritzgussverfahren mit geringem Aufwand herstellen.Depending on the requirements of the subsequent to the suction jet pump line, it may be advantageous if the outlet end of the mixing tube and the line section consist of different materials. Such a designed mixing tube with a line section leaves Produce in two-component injection molding process with little effort.
In einer anderen vorteilhaften Ausgestaltung weist das Aus- lassende einer als Diffusor ausgebildetes Innenkontur auf.In another advantageous embodiment, the outlet end of a designed as a diffuser inner contour.
Verwirbelungen am Mischrohrende lassen sich gemäß einer weiteren vorteilhaften Ausgestaltung dadurch vermeiden, dass der Diffusor stetig in den Innendurchmesser des Leitungsab- Schnitts übergeht.Turbulence at the mixing tube end can be avoided according to a further advantageous embodiment in that the diffuser continuously merges into the inner diameter of the line section.

Die in Figur 1 dargestellte Saugstrahlpumpe nach dem Stand der Technik besitzt ein Gehäuse 1, in welchem eine Treibdüse 2 angeordnet ist. Der Treibdüse 2 wird über einen Anschluss 3 Kraftstoff als Treibmittel zugeführt, so dass der Treibstrahl aus der Treibdüse 2 heraus über einen Einlassbereich in das Mischrohr 5 spritzt. In Strömungsrichtung hinter dem Einlassbereich 4 folgt ein Konfusor 6, der jedoch nicht zwingend notwendig ist. Ihm folgt ein Mischbereich 7 konstanten Quer- Schnitts, dem im Bereich des Auslassendes ein Diffusor 8 folgt. Am Auslassende 8 des Mischrohres 5 ist an dessen Um¬ fang ein Tannenbaumprofil 9 angeformt, auf das ein Leitungs¬ abschnitt 10 aufgesteckt ist. Über die Leitung 10 wird der von der Saugstrahlpumpe abgegebene Summenstrahl abgeleitet. Der Summenstrahl setzt sich aus dem Treibstrahl und dem geförderten Kraftstoff zusammen, wobei der geförderte Kraft¬ stoff aufgrund des von dem Treibstrahl im Bereich des Ein- lassbereichs 4 erzeugten Unterdrucks über den Ansaugbereich 11 angesaugt wird.The suction jet pump according to the prior art shown in Figure 1 has a housing 1, in which a driving nozzle 2 is arranged. The propellant nozzle 2 is supplied with fuel as a propellant via a port 3, so that the motive jet from the propulsion nozzle 2 is injected into the mixing tube 5 via an inlet region. In the flow direction behind the inlet region 4 is followed by a Confusor 6, which is not absolutely necessary. It is followed by a mixing region 7 of constant cross-section, followed by a diffuser 8 in the region of the outlet end. At the outlet end 8 of the mixing tube 5, a Christmas tree profile 9 is formed on the order ¬ catch to which a line ¬ section 10 is attached. Via the line 10 of the output from the ejector pump sum beam is derived. The sum of the jet is composed of the propellant jet and the pumped fuel, wherein the pumped Kraft ¬ material due to the of the propulsion jet in the region of Ein- 4 negative pressure generated is sucked in via the suction region 11.
