Definitions
- the invention relates to an impeller for a liquid ring machine
- the object is achieved in that the front of the impeller hub and / or on the rear of the support disc there is at least one depression for edge formation.
- the back of the support disc and / or on the front of the The growing layers become impeller hub continuously scraped off and transported to the outside with the operating fluid or discharged through the support plate slot.
- Combinations of different wells that are used for Edge formation is possible. This is how material bores can be can be combined with grooves and / or slots, just like Grooves with through holes.
- FIG. 1 shows in cross section an impeller 1 on the front side the impeller hub 2, which is designed as a sealing surface 7 has grooves 3.
- 2 shows a longitudinal section of the Impeller 1, the 4 recesses on the back of the support disk with edge formation 8, which in this case as a slot 6 and groove 3 are formed.
- 3 shows this in cross section Impeller 1, which is on the front of the impeller hub 2 by 180 ° has offset grooves 3, but each of the sealing surface 7 Do not fully penetrate the impeller hub 1.
- Fig. 4 and FIG. 5 show slots 6 in perspective in the support disc and grooves 3 in the impeller hub front Second

Claims (6)
- Laufrad (1) für eine Flüssigkeitsringmaschine, das eine Vielzahl von mit der Nabe des Laufrades und einer Tragscheibe verbundenen Schaufel aufweist, wobei die Stirnseite der Laufradnabe (2) und Tragscheibenrückseite (4) Dichtflächen aufweisen, dadurch gekennzeichnet, dass sich an der Stirnseite der Laufradnabe (2) und/oder an der Tragscheiberückseite (4) mindestens eine Vertiefung zur Kantenbildung (8)befindet, die auf der Tragscheibenrückseite (4) und/oder an der Stirnseite der Laufradnabe (2) entstehende Schichten verhindert, so dass ein Zuwachsen der Axialspalte bis zum Festsetzen des Laufrades oder ein axiales Wegschieben des Laufrades verhindert wird.
- Laufrad (1) für eine Flüssigkeitsringmaschine nach Anspruch 1, dadurch gekennzeichnet, daß die Vertiefung zur Kantenbildung (8) aus Nuten (3) und/oder Sackbohrungen besteht.
- Laufrad (1) für eine Flüssigkeitsringmaschine nach Anspruch 2, d a durch gekennzeichnet, daß die Vertiefungen zur Kantenbildung (8) axial durchgängig sind.
- Laufrad (1) für eine Flüssigkeitsringmaschine nach Anspruch 3, dadurch gekennzeichnet, daß die durchgängigen Vertiefungen (8) aus Schlitzen (6) und/oder Bohrungen bestehen.
- Laufrad (1) für eine Flüssigkeitsringmaschine nach einem der vorhergehenden Ansprüche, dadurch gekennzeichnet, daß die Nuten (3) und/oder Schlitze (6) im Wesentlichen in radialer Richtung verlaufen.
- Laufrad (1) für eine Flüssigkeitsringmaschine nach Anspruch 5, dadurch gekennzeichnet, daß die radiale Ausdehnung der Nuten (3) und/oder Schlitze (6) kleiner ist als die radiale Ausdehnung der jeweiligen Dichtfläche an Tragscheiben-rückseite (4) und/oder Laufradnabenstirnseite (2).
