Description
Beschreibung description
Strömungsmaschine flow machine
Gegenstand der Erfindung ist eine Strömungsmaschine mit ei¬ nem Gehäuse, einem in dem Gehäuse angeordneten Elektromo¬ tor, wobei der Elektromotor einen Stator und einen auf einer Welle angeordneten Rotor, mindestens einem von der Welle angetriebenen Laufrad mit mindestens einem Kranz von Schaufelkammern begrenzenden Laufschaufeln, welches in einem Pumpengehäuse angeordnet ist, und mit im Pumpengehäuse angeordneten und je einem Kranz von Schaufelkammern gegenüberliegendem Seitenkanal, der sich von einem Pumpeneinlass bis zu einem Pumpenauslass erstreckt. The invention relates to a turbomachine with egg ¬ nem housing, an arranged in the housing Elektromo ¬ tor, wherein the electric motor comprises a stator and a rotor arranged on a shaft, at least one driven by the shaft impeller with at least one ring of blade chambers bounding blades, which is arranged in a pump housing, and disposed in the pump housing and each a ring of vane chambers opposite side channel extending from a pump inlet to a pump outlet.
Solche Strömungsmaschinen sind seit langem bekannt und werden zum Fördern von Flüssigkeiten, insbesondere Kraftstoff, oder zum Fördern von Gasen, insbesondere Luft, verwendet. Über den Pumpeneinlass wird das zu fördernde Medium ange¬ saugt und über den Seitenkanal und die Schaufelkammern zum Pumpenauslass gefördert. Dabei zirkuliert die Strömung zwi¬ schen Seitenkanal und Schaufelkammern. Nachteilig ist, dass beim Übergang in oder von der Zirkulationsströmung Strömungsverluste auftreten. Such turbomachines have long been known and are used for conveying liquids, in particular fuel, or for conveying gases, in particular air. The pumped medium is ¬ sucked and discharged through the side channel and the blade chambers to the pump through the pump inlet. In this case, the flow rule Zvi ¬ side channel and vane chambers circulates. The disadvantage is that flow losses occur during the transition to or from the circulation flow.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Strö¬ mungsmaschine zu schaffen, welche geringere Strömungsver¬ luste aufweist. The invention is therefore based on the object to provide a Strö ¬ tion machine, which has lower Strömungsver ¬ losses.
Gelöst wird die Aufgabe dadurch, dass am Ende des Seitenka¬ nals in der radial inneren Hälfte des Seitenkanal eine Ram¬ pe angeordnet ist, die vom Kanalgrund beginnend in Strö¬ mungsrichtung bis auf die Höhe der Pumpengehäusewand an¬ steigt und der Seitenkanal mit seiner radial außen liegen¬ den Hälfte in den Pumpenauslass übergeht.
Mit der Anordnung der Rampe wird der Teil der Zirkulations¬ strömung, welcher in den Seitenkanal eintritt, umgeleitet. Gleichzeitig gelangt nur der aus dem Seitenkanal austreten¬ de Teil der Zirkulationsströmung zum Pumpenauslass , da der Seitenkanal lediglich mit seiner radial außen liegenden Hälfte in den Pumpenauslass übergeht. Mit der Auswahl des Teils der Strömung, die in den Pumenauslass strömt, und dem Umleiten des anderen Teils werden insgesamt verbesserte Strömungsverhältnisse erreicht, die weniger Strömungsver- luste und somit einen verbesserten Wirkungsgrad der Strö¬ mungsmaschine zur Folge haben. Zudem besitzt der Übergang zum Pumpenauslass einen kleineren Querschnitt als bislang üblich, wodurch es zu einer weiteren Druckerhöhung des zu fördernden Mediums kommt. Ein weiterer Vorteil besteht da- rin, dass die konstruktiven Maßnahmen keine zusätzlichenThe object is achieved in that at the end of the Seitenka ¬ nals in the radially inner half of the side channel Ram ¬ pe is arranged, which increases from the channel bottom in Strö ¬ tion direction up to the height of the pump housing wall ¬ and the side channel with its radial outside lie ¬ half in the pump outlet merges. With the arrangement of the ramp, the part of the circulation ¬ flow, which enters the side channel, redirected. At the same time only reaches the exit from the side channel ¬ de part of the circulation flow to the pump, since the side-channel only passes with its radially outer half in the pump outlet. With the selection of the part of the flow which flows into the Pumenauslass, and the redirecting of the other part overall improved flow conditions are achieved, which have less flow losses and thus an improved efficiency of the Strö ¬ tion machine result. In addition, the transition to the pump outlet has a smaller cross-section than hitherto usual, resulting in a further increase in pressure of the medium to be delivered. Another advantage is that the design measures do not require any additional measures
Kosten verursachen, so dass die Strömungsmaschine mit ver¬ besserten Eigenschaften bei gleichen Kosten hergestellt werden kann. Es hat sich gezeigt, dass eine zuverlässige Umleitung der Teilströmung dann erreicht wird, wenn die Oberfläche der Rampe konvex in Richtung des Laufrades gewölbt ist. Costs cause, so that the turbomachine with ver ¬ improved properties can be produced at the same cost. It has been found that a reliable diversion of the partial flow is achieved when the surface of the ramp is curved convexly in the direction of the impeller.
In Abhängigkeit von den geometrischen Abmessungen und den Druckverhältnissen hat sich eine Länge der Rampe von 10° bis 50° der Seitenkanallänge herausgestellt. Depending on the geometric dimensions and the pressure conditions, a length of the ramp of 10 ° to 50 ° of the Seitenkanallänge has been found.
Sofern sich die Mündung des Seitenkanals in den Pumpenaus¬ lass in Strömungsrichtung gesehen nach der Rampe an- schließt, erfolgt eine gute Umleitung der Teilströmung mit anschließendem Überströmen zum Pumpenauslass. If the mouth of the side channel in the pump outlet is connected downstream of the ramp, as seen in the flow direction, the partial flow is well diverted with subsequent overflow to the pump outlet.
Eine verlängerte wirksame Seitenkanallänge wird gemäß einer anderen Ausgestaltung dadurch erreicht, dass die Rampe in Strömungsrichtung versetzt wird, so dass sich die Anordnung der Rampe und die Mündung des Seitenkanals in den Pumpen¬ auslass in Strömungsrichtung gesehen überlappen.
Sofern sich beim Übergang vom Seitenkanal in den Pumpenauslass Verwirbelungen bilden, können diese dadurch minimiert werden, dass sich der Durchmesser der Mündung des Seitenka- nals in den Pumpenauslass in Strömungsrichtung stetig auf einen größeren Durchmesser des Pumpenauslasses erweitert. Durch die Querschnittsvergrößerung erfolgt eine Beruhigung der Strömung, die geringfügigen Druckverluste sind dabei vernachlässigbar . An extended effective Seitenkanallänge is achieved according to another embodiment in that the ramp is offset in the flow direction, so that overlap the arrangement of the ramp and the mouth of the side channel in the pump ¬ outlet seen in the flow direction. If turbulences form during the transition from the side channel into the pump outlet, these can be minimized by the fact that the diameter of the mouth of the side channel in the pump outlet widens continuously in the flow direction to a larger diameter of the pump outlet. Due to the cross-sectional enlargement, a calming of the flow, the slight pressure losses are negligible.
