发明名称 Turbo machine and method to reduce vibration in turbo machines
摘要 A turbo machine (1) comprises a casing (2) and a first volute tongue (12), an impeller (3) with at least one vane (4), and a flow splitter plate (5) comprising a second volute tongue (13) for splitting a flow of a fluidic medium produced by the impeller. The flow splitter plate comprises at least one opening (10) connecting the first surface (8) and the second, opposite surface (9) so as to reduce or eliminate vibrations.

主权项 1. A turbo machine comprising: a casing defining a first volute tongue, an impeller with at least one vane, and a flow splitter plate defining a second volute tongue at an upstream end of the flow splitter plate for splitting a flow of a fluidic medium produced by the impeller, the flow splitter plate extending in a splitter plane that is situated essentially parallel to the direction of the flow, the flow splitter plate having a first surface and a second, opposite surface, wherein the flow splitter plate includes a series openings forming a perforated area and each opening extending through the flow splitter plate from the first surface to the second opposite surface, wherein the perforated area is positioned adjacent a downstream end of the flow splitter plate.
