Abstract
Die Erfindung betrifft ein Gehäuse (2) mit mindestens einer Gehäusestrukturierung zum Stabilisieren der Strömung im Bereich der Blattspitzen der Laufschaufeln (4) in einer Strömungsarbeitsmaschine, wobei die Gehäusestrukturierung mindestens in einer Stufe am inneren Umfang des Gehäuses (2) angeordnet ist.The invention relates to a housing (2) with at least one housing structuring for stabilizing the flow in the area of the blade tips of the rotor blades (4) in a fluid flow machine, wherein the housing structuring is arranged at least in one step on the inner circumference of the housing (2).
Um ein Gehäuse zu schaffen, das die Verdichterstabilität erhöht, einfach aufgebaut ist, ein geringes Gewicht aufweist, zuverlässig funktioniert und das Fluid in der Strömungsarbeitsmaschine nicht erhitzt, ist die Gehäusestrukturierung als Kanal (20) ausgebildet, der ein erstes Ende (21) und ein zweites Ende (22) umfasst, wobei das erste Ende (21) im Bereich der Blattspitzen eines Laufschaufelkranzes in das Innere des Gehäuses (2) mündet und das zweite Ende (22) geschlossen ist. In order to provide a housing that increases compressor stability, is simple in construction, lightweight, reliable, and does not heat fluid in the fluid power machine, the housing structure is formed as a channel (20) having a first end (21) and a second end second end (22), wherein the first end (21) opens in the region of the blade tips of a blade ring in the interior of the housing (2) and the second end (22) is closed.
