Abstract
(DE) Die Erfindung betrifft eine Strömungsmaschine (1), insbesondere Pumpe oder Turbine, umfassend ein Laufrad (2), das in einem Laufradraum (3) eines Gehäuses (4) der Strömungsmaschine (1) drehbar um eine Rotationsachse (A) angeordnet ist. Dabei ist zum Energieaustausch zwischen einer Strömungsenergie eines strömenden Fluids (F) und einer mechanischen Rotationsenergie, das Fluid (F) dem Gehäuse (4) der Strömungsmaschine derart zuführbar, dass es zum Energieaustausch mit dem Laufrad (2) in strömenden Kontakt bringbar ist, und aus dem Gehäuse (4) der Strömungsmaschine wieder abführbar ist. Erfindungsgemäss ist ein um die Rotationsachse (A) in einer Umfangsrichtung (U) des Laufrads (2) verlaufendes Strömungsleitelement (5, 51, 52) derart im Laufradraum (3) zwischen einer Innenwand (31) des Laufradraums (3) und dem Laufrad (2) vorgesehen, dass das Laufrad (2) vom Strömungsleitelement (5, 51, 52) in einer vorgebbaren axialen Breite (B) umschlossen ist. Desweiteren betrifft die Erfindung ein Strömungsleitelement (5, 51, 52) für eine Strömungsmaschine (1).
(EN) The invention relates to a turbomachine (1), in particular a pump or turbine, comprising an impeller (2) which is arranged in an impeller area (3) of a housing (4) of the turbomachine (1) in a rotatable manner about a rotational axis (A). In order to exchange energy between a flow energy of a flowing fluid (F) and a mechanical rotational energy, the fluid (F) can be fed to the housing (4) of the turbomachine such that the fluid can be brought into fluidic contact with the impeller (2) so as to exchange energy and can be discharged again out of the housing (4) of the turbomachine. According to the invention, a flow conducting element (5, 51, 52) which runs about the rotational axis (A) in a circumferential direction (U) of the impeller (2) is provided in the impeller area (3) between an inner wall (31) of the impeller area (3) and the impeller (2) such that the impeller (2) is surrounded by the flow conducting element (5, 51, 52) with a specifiable axial width (B). The invention further relates to a flow conducting element (5, 51, 52) for a turbomachine (1).
(FR) L'invention concerne une turbomachine (1), en particulier une pompe ou une turbine, comprenant un rotor (2) qui est monté rotatif sur un axe de rotation (A) dans une chambre de rotor (3) d'un carter (4) de la turbomachine (1). Selon l'invention, pour l'échange d'énergie entre l'énergie d'écoulement d'un fluide (F) et une énergie de rotation mécanique, le fluide (F) peut être alimenté dans le carter (4) de la turbomachine de manière à pouvoir être amené en contact d'écoulement pour l'échange d'énergie avec le rotor (2), puis être évacué du carter (4) de la turbomachine. Selon l'invention, un guide d'écoulement (5, 51, 52) qui s'étend autour de l'axe de rotation (A) dans une direction circonférentielle (U) du rotor (2) est disposé dans la chambre de rotor (3) entre une paroi intérieure (31) de la chambre de rotor (3) et le rotor (2) de telle manière que le rotor (2) est entouré par le guide d'écoulement (5, 51, 52) dans une largeur axiale prédéfinie (B). L'invention concerne en outre un guide d'écoulement (5, 51, 52) destiné à une turbomachine (1).
