There is screw-form medium guide in the outer housing and the shape of the inner part and the outer housing corresp. to the selected cross current runner activation is either circular, elliptical, triangular or polygonal. The cross current runner is fixed directly on the shaft of the flange motor. USE/ADVANTAGE - To increase the degree of effect and the delivery pressure of a cross current flow machine for fluid and gas media.

Description

Querstromströmungsmaschinen für flüssige und gasförmige Medien sind als mehrstufige Aggregate oder Kombimaschinen mit einfach beaufschlagten Trommelläufern aus den Schriften DE 36 28 946 C2 und der DE 38 28 316 C2 bekannt.Cross flow machines for liquid and gaseous Media are as multi-stage aggregates or combination machines with simply loaded drum rotors from the scriptures DE 36 28 946 C2 and DE 38 28 316 C2 are known.

Aufgabe der Erfindung ist es den bisherigen Wirkungsgrad und den Förderdruck der Querstromströmungsmaschinen zu er­ höhen.The object of the invention is the previous efficiency and the delivery pressure of the cross-flow flow machines to it heights.

Die Aufgabe wird erfindungsgemäß mit den Merkmalen des An­ spruchs 1 gelöst. Weitere vorteilhafte Merkmale beinhalten die Unteransprüche.The object is achieved with the features of the An spell 1 solved. Include other advantageous features the subclaims.

In den Fig. 1 und 2 ist ein äußeres Gehäuse mit einfluti­ gen Laufrad in Einfachbeaufschlagung dargestellt. Äußeres Gehäuse (1) mit Innenteil in Kreisform, einflutiges Lauf­ rad (2), Distanzhülse (3), Welle (4), Wellenkeil (5), Nase (6) am Innenteil zum stoßfreien Anströmen des Ringgitters des Laufrades und Überströmkanals (7).In Figs. 1 and 2, an outer casing is shown with impeller einfluti gene in Einfachbeaufschlagung. Outer housing ( 1 ) with inner part in circular shape, single-flow impeller ( 2 ), spacer sleeve ( 3 ), shaft ( 4 ), shaft wedge ( 5 ), nose ( 6 ) on the inner part for smooth flow against the ring grille of the impeller and overflow channel ( 7 ) .

Gemäß dieser Erfindung werden an Stelle der bekannten Läu­ ferwalzen Einzelräder für Aggregate in ein- oder doppel­ flutiger Bauweise, gemäß Fig. 3 und 4, verwendet. Diese bekannte Bauweise wird in großen Stückzahlen in Radialma­ schinen eingesetzt.According to this invention, instead of the known Läu ferwalzen single wheels for units in single or double flow design, as shown in FIGS. 3 and 4, are used. This known design is used in large quantities in radial machines.

Zur Vermeidung des Innenwirbels, der für den ungenügenden Druckaufbau und schlechteren Wirkungsgrad oben genannter Querstromströmungsmaschinen verantwortlich ist, wird das bisherige äußere Gehäuse um einen Innenteil erweitert. To avoid the inner vertebra, which is insufficient for the Pressure build-up and poor efficiency of the above Cross-flow machines is responsible for that previous outer housing extended by an inner part.  

Durch das erfindungsgemäße Verändern der inneren sowohl auch der äußeren Gehäuseform vom Kreis zur Ellypse, Drei- oder Mehreckform ist die Mehrfachbeaufschlagung des Ein­ zelradmoduls möglich. Damitt ist die Fertigung von Quer­ stromströmungsmaschinen in Kompaktbauweise gegeben. Diese erfindungsgemäße Konstruktion gestattet bei gleichem Außendurchmesser des Laufrades, bei gleicher Dreh- und Stufenzahl, eine Reduzierung des Bauaufwandes zu bisherigen ausgeführten Maschinen.By changing the inner both according to the invention also the outer shape of the housing from the circle to the ellipsis, three or polygonal form is the multiple application of the one gear module possible. Damitt is the manufacture of Quer current flow machines in a compact design. These Construction according to the invention allows the same Outside diameter of the impeller, with the same turning and Number of stages, a reduction in construction costs compared to previous ones running machines.

Zwei Ausführungsbeispiele von Querstromströmungsmaschinen mit mehrfach beaufschlagten Laufradmodulen werden an Hand der Fig. 5 bis 8 erläutert.Two exemplary embodiments of cross-flow flow machines with multi-impeller modules are explained with reference to FIGS . 5 to 8.

Die Fig. 5 und 6 zeigen eine 4stufige Querstromströmungsmaschine in Kompaktbauweisse. FIGS. 5 and 6 show a 4-stage cross-flow turbomachine in Kompaktbauweisse.

Äußeres Gehäuse mit Lagerbock (1), dieser entfällt nebst Kupplung bei Verwendung eines Flanschmotors, doppelflutiges Laufrad (2), Nasen (6) am Innenteil zur stoßfreien Anströmung des Schaufelradringgitters, Überströmkanal (7), vorderer Gehäusedeckel (8) und Labyrinthdichtung (9).Outer housing with bearing block ( 1 ), this is omitted together with the coupling when using a flange motor, double-flow impeller ( 2 ), lugs ( 6 ) on the inner part for smooth flow against the vane ring grille, overflow channel ( 7 ), front housing cover ( 8 ) and labyrinth seal ( 9 ) .

Das Medium durchströmt gemäß Fig. 5 die Querstromströmungsmaschine vom Ansaugstutzen kommend in Laufraddreh­ richtung zweimal.The medium flows through according to FIG. 5, the cross-flow turbomachine intake from coming in the impeller rotation direction twice.

Es handelt sich somit um eine zweistufige Maschine im Sinne der DE 36 28 946 C2, wobei jedes Radmodul zweimal durchströmt (beaufschlagt) wird. Der Saugstutzen kann wahlweise wie gezeichnet (tangential) aber auch im Ge­ häusedeckel (parallel zur Achsrichtung) angeordnet sein.It is therefore a two-stage machine in the sense DE 36 28 946 C2, each wheel module twice is flowed through (acted upon). The suction port can optionally as drawn (tangential) but also in ge  housing cover (parallel to the axis direction).

In Fig. 7 und Fig. 8 ist eine Kombimaschine (Pumpe-Tur­ bine=Wandler) in Viereckkonfiguration dargestellt. Beide Maschinenhälften besitzen je ein einflutiges Laufrad, wo­ bei jedes dreimal durchströmt (beaufschlagt) wird. Hier ist mit Ziffer 7 der Überströmkanal und mit 10 die Kupp­ lung bezeichnet. Die Kupplung ist unabhängig von der Kombi­ maschine (Pumpe-Turbine) zu betrachten und dient zur Verbindung beider Seiten nach Drehzahlausgleich. Es handelt sich somit hier um eine Kombimaschine, die aus zwei einstufigen Maschinen im Sinne der DE 36 28 946 C2 be­ steht. Die Leistungsübertragung gegenüber der DE 38 28 316 C2 ist jedoch durch die Vermeidung des Innenwirbels und die Mehrfachbeaufschlagung der Laufräder hier erheblich verbessert.In Fig. 7 and Fig. 8, a combination machine (pump-tur bine = converter) is shown in a square configuration. Both halves of the machine each have a single-flow impeller, each of which is flowed through three times. Here, the overflow channel is designated with numeral 7 and the coupling with 10 . The coupling is to be considered independently of the combination machine (pump-turbine) and serves to connect both sides after speed compensation. It is therefore a combination machine that consists of two single-stage machines in the sense of DE 36 28 946 C2. The power transmission compared to DE 38 28 316 C2 is, however, considerably improved here by avoiding the inner vortex and the multiple impingement of the impellers.
