Abstract

Przedmiotem zgłoszenia jest wirnik promieniowy pompy wirowej o zmniejszonych oporach przepływu, składający się z piasty (1), połączonej lub wykonanej jako jedna całość z tarczą tylną (3), na której osadzone są łopatki główne (4) tworzące kanały międzyłopatkowe otwarte lub zamknięte tarczą przednią (2), charakteryzujący się tym, że na wewnętrznej powierzchni tarczy tylnej (3) i na wewnętrznej powierzchni tarczy przedniej (2) wykonane są wgłębienia (5).The subject of the application is a radial rotor of a centrifugal pump with reduced flow resistance, consisting of a hub (1) connected or made as one whole with a rear disc (3), on which main blades (4) are mounted, forming inter-blade channels open or closed by a front disc (2), characterized in that recesses (5) are made on the inner surface of the rear disc (3) and on the inner surface of the front disc (2).
