Abstract

Uszczelnienie wału w układzie pionowym z zastosowaniem cieczy magnetycznej, zawierającego obudowę, stopniowaną tuleję, wielokrawędziowy nabiegunnik, magnes trwały i ciecz magnetyczną, charakteryzuje się tym, że w stopniowanej tulei (5), osadzonej na wale pionowym (1), wykonane jest wytoczenie (5a) usytuowane w dolnej części tulei (5), w którym umocowany jest wielokrawędziowy nabiegunnik (6) o przekroju poprzecznym teowym, którego dolna część w postaci tulejki (6a) posiada występy uszczelniające, wykonane na jej powierzchniach cylindrycznych - zewnętrznej oraz wewnętrznej, a ponadto na dnie wytoczenia (4a) wykonanego w obudowie uszczelnienia (4) od strony jej górnej powierzchni czołowej, umieszczony jest magnes trwały (7) spolaryzowany promieniowo, nad którym usytuowana jest z luzem tulejka (6a) wielokrawędziowego nabiegunnika (6), zaś ciecz magnetyczna (8) znajduje się w pierścieniowych szczelinach (?), utworzonych pomiędzy występami uszczelniającymi nabiegunnika (6), a odpowiednimi powierzchniami cylindrycznymi w wytoczeniu (4a) obudowy uszczelnienia (4).Vertical shaft seal using a magnetic fluid, including a housing, stepped sleeve, multi-edge pole piece, permanent magnet and magnetic fluid, characterized in that a stepped sleeve (5) mounted on the vertical shaft (1) has a boring (5a ) located in the lower part of the sleeve (5), in which a multi-edge pole piece (6) with a T-cross section is mounted, the lower part of which in the form of a sleeve (6a) has sealing projections, made on its cylindrical surfaces - external and internal, and in addition the bottom of the groove (4a) made in the seal housing (4) from its upper face, a permanent magnet (7) is placed radially polarized, above which the sleeve (6a) of the multi-edge pole piece (6) is located, and the magnetic liquid (8) ) is located in the annular gaps (?) formed between the sealing lips n binder (6), and corresponding cylindrical surfaces in the groove (4a) of the seal housing (4).
