Abstract

Przedmiotem zgłoszenia jest osłona wirnika przepływowej maszyny promieniowej (1, 2), zwłaszcza wentylatora promieniowego, charakteryzuje się tym, że osłona wykonana w formie powierzchni walcowych umieszczona w obszarze zewnętrznej średnicy wirnika (3) kształtuje małą szczelinę pomiędzy nieruchomą obudową wentylatora (4), a spiralnym wylotem z wirnika wentylatora od strony wlotowej (szczelina 5) i od strony tylnej (szczelina 6).The subject of the application is a cover for the rotor of a centrifugal flow machine (1, 2), especially a centrifugal fan, characterized by the fact that the cover made in the form of cylindrical surfaces, placed in the area of the outer diameter of the rotor (3), forms a small gap between the stationary fan casing (4) and spiral outlet from the fan impeller on the inlet side (slot 5) and on the rear side (slot 6).
