Abstract

Przedmiotem zgłoszenia jest przepust wału szybkoobrotowego uszczelniony za pomocą uszczelnień z cieczą ferromagnetyczną, stosowany w budowie maszyn i urządzeń, pracujących w środowisku cieczy i gazu. Przepust wału szybkoobrotowego uszczelniony za pomocą uszczelnień z cieczą ferromagnetyczną, charakteryzuje się tym ,że ma w komorze utworzonej pomiędzy łożyskami tocznymi (3) osadzonymi na wale obrotowym (1) i w obudowie (2), umieszczone wielokrawędziowe nabiegunniki (10) z występami uszczelniającymi wykonanymi na ich wewnętrznych powierzchniach cylindrycznych i przedzielone dwoma magnesami trwałymi (8, 9), które przylegają biegunami N do bocznych powierzchni środkowego wielokrawędziowego nabiegunnika (10), zaś w obudowie (2) po zewnętrznych stronach łożysk tocznych (3) umieszczone są uszczelnienia odśrodkowe z cieczą ferromagnetyczną (7).The subject of the application is a high-speed shaft bushing sealed with ferromagnetic liquid seals, used in the construction of machines and devices operating in a liquid and gas environment. The high-speed shaft bushing sealed with ferromagnetic fluid seals is characterized by the fact that in the chamber formed between the rolling bearings (3) mounted on the rotary shaft (1) and in the housing (2), multi-edge pole pieces (10) with sealing lugs made on their internal cylindrical surfaces and separated by two permanent magnets (8, 9), which adhere with N poles to the side surfaces of the central multi-edge pole piece (10), and in the housing (2), on the outer sides of the rolling bearings (3), there are centrifugal seals with ferromagnetic liquid (7).
