Abstract
Uszczelnienie wału w układzie pionowym z zastosowaniem cieczy magnetycznej zawierające stopniowaną tuleję ruchomą, pokrywę, wielokrawędziowe nabiegunniki, magnes trwały spolaryzowany promieniowo i ciecz magnetyczną, charakteryzuje się tym, że w stopniowanej tulei ruchomej (4) osadzonej na wale pionowym (1) wykonana jest pierścieniowa wnęka (4a) usytuowana w wystającej od dołu części tulei (4), w której umocowane są wielokrawędziowe nabiegunniki (7, 8) przedzielone magnesem trwałym (6). Pokrywa (5) zamocowana do obudowy (2), zaopatrzona jest w pierścieniową przegrodę (5a), która umieszczona jest z luzem pomiędzy wielokrawędziowymi nabiegunnikami (7, 8) i magnesem trwałym (6). Ciecz magnetyczna (9) znajduje się w szczelinach pierścieniowych (?) utworzonych pomiędzy występami uszczelniającymi wykonanymi na powierzchniach cylindrycznych wielokrawędziowych nabiegunników (7, 8), a zewnętrzną powierzchnią walcową oraz wewnętrzną powierzchnią cylindryczną pierścieniowej przegrody (5a) pokrywy (5).Vertical shaft seal with the use of a magnetic liquid containing a stepped movable sleeve, a cover, multi-edge pole shoes, a radially polarized permanent magnet and a magnetic liquid, characterized by the fact that in the stepped movable sleeve (4) mounted on the vertical shaft (1) there is an annular cavity (4a) located in the part protruding from the bottom of the sleeve (4), in which the multi-edge pole pieces (7, 8) separated by a permanent magnet (6) are mounted. The cover (5) attached to the housing (2) is provided with an annular partition (5a), which is placed with a play between the multi-edge pole pieces (7, 8) and the permanent magnet (6). The magnetic fluid (9) is contained in the annular gaps (?) Formed between the sealing projections made on the cylindrical surfaces of multi-edge pole pieces (7, 8) and the outer cylindrical surface and the inner cylindrical surface of the annular partition (5a) of the cover (5).
