Abstract

Uszczelnienie wielostopniowe z cieczą magnetyczną zawiera co najmniej jeden podzespół uszczelniający (A) zabudowany pomiędzy wałem (1), a obudową (2), składający się z nabiegunników o przekroju teowym (3) osadzonych na wale (1) lub w obudowie (2), które mają występy uszczelniające wykonane na zewnętrznych lub wewnętrznych powierzchniach walcowych kołnierzy (3a). Na tulejkach kołnierzowych (4) również o przekroju teowym, osadzonych na wale (1) lub w obudowie (2) przeciwległe do nabiegunników o przekroju teowym (3) umieszczone są magnesy trwałe (5, 6), przylegające do bocznych powierzchni kołnierzy (4a) oraz nabiegunniki o przekroju prostokątnym (7) przylegające do magnesów (5, 6) z ich drugiej strony. Ciecz magnetyczna (8) znajduje się w pierścieniowych szczelinach, utworzonych pomiędzy występami uszczelniającymi nabiegunników o przekroju teowym (3), a walcowymi powierzchniami kołnierzy (4a) tulejek kołnierzowych (4) oraz w pierścieniowych szczelinach pomiędzy występami uszczelniającymi nabiegunników o przekroju prostokątnym (7), a odpowiednimi zewnętrznymi lub wewnętrznymi powierzchniami walcowymi nabiegunników o przekroju teowym (3).The multi-stage seal with magnetic fluid contains at least one sealing subassembly (A) built between the shaft (1) and the housing (2), consisting of T-shaped pole pieces (3) mounted on the shaft (1) or in the housing (2), which have sealing projections on the outer or inner surfaces of cylindrical flanges (3a). On the flange bushes (4) also with T-shaped, mounted on the shaft (1) or in the housing (2) opposite to the pole-pieces with a T-section (3), permanent magnets (5, 6) are placed, adjacent to the flange side surfaces (4a) and rectangular pole pieces (7) adjacent to magnets (5, 6) from their other side. The magnetic fluid (8) is located in the annular gaps formed between the sealing protrusions of the T-shaped pole shoes (3) and the cylindrical flange surfaces (4a) of the flange bushes (4) and in the annular gaps between the sealing protrusions of the rectangular pole pieces (7), and respective outer or inner cylindrical surfaces of T-shaped pole pieces (3).
