Abstract

Przedmiotem zgłoszenia jest wirnik wentylatora promieniowego, dostosowany do ekonomicznej zmiany parametrów przepływowych. Cel ten osiągnięto poprzez określone obrotowe mocowanie końcówek (3) łopatek (4) i zmienne ustawienie na wylocie względem tarczy nośnej (7) i pokrywy (8).The subject of the application is a centrifugal fan impeller adapted to economically change the flow parameters. This purpose is achieved by a specific rotatable mounting of the tips (3) of the blades (4) and variable positioning at the outlet relative to the carrier disc (7) and the cover (8).
