Abstract
Acoplamiento entre un rodete centrífugo y su boca de aspiración, comprendiendo una boca de aspiración (1) que determina una abertura (2) para el paso de un flujo de fluido en aspiración y un rodete centrífugo (3) incorporado en montaje giratorio que hace la aspiración, estableciéndose entre dicho rodete centrífugo (3) y la boca de aspiración (1) un acoplamiento de cierre alrededor de la abertura (2), mediante un encaje múltiple entre alas (7) del rodete centrifugo (3) y alas (8) de la boca de aspiración (1), las cuales determinan entre ellas un paso laberintico que dificulta la entrada de un flujo perturbador de aire a través del acoplamiento.Coupling between a centrifugal impeller and its suction mouth, comprising a suction mouth (1) that determines an opening (2) for the passage of a fluid flow in suction and a centrifugal impeller (3) incorporated in a rotating assembly that makes the suction, establishing between said centrifugal impeller (3) and the suction mouth (1) a closing coupling around the opening (2), by means of a multiple fit between wings (7) of the centrifugal impeller (3) and wings (8) of the suction mouth (1), which determine between them a labyrinth passage that hinders the entry of a disturbing flow of air through the coupling.
