Abstract

Wielostopniowe uszczelnienie z cieczą magnetyczną dla wałów obrotowych, stosowane w maszynach i urządzeniach pracujących w środowisku gazowym przy niewielkich ciśnieniach lub w warunkach wysokiej próżni, zawierające tulejki kołnierzowe, magnesy trwałe spolaryzowane osiowo, nabiegunniki i ciecz magnetyczną charakteryzuje się tym, że pary nabiegunników (4) przedzielone magnesami trwałymi (5) osadzone są w komorze dławnicowej obudowy (2), a tulejki kołnierzowe (3) z magnesami trwałymi (6) umieszczonymi we wnękach usytuowanych na wewnętrznych powierzchniach cylindrycznych tulejek (3), osadzone są na wale (1), przy czym kołnierze (3a) tulejek (3) położone są w komorach utworzonych przez sąsiednie nabiegunniki (4) przedzielone magnesami trwałymi (5), a zewnętrzne powierzchnie stożkowe kołnierzy (3a) tulejek kołnierzowych (3) i wewnętrzne powierzchnie stożkowe nabiegunników (4) tworzą szczeliny zbieżne o kącie pochylenia (?) ponadto na zewnętrznych powierzchniach walcowych tulejek (3) wykonane są występy uszczelniające.Multi-stage magnetic fluid sealing for rotating shafts, used in machines and equipment operating in a gas environment at low pressures or in high vacuum conditions, containing flange bushes, axially polarized permanent magnets, pole shoes and magnetic fluid is characterized by the fact that pairs of pole shoes (4) separated by permanent magnets (5) are embedded in the stuffing box of the housing (2), and flange bushes (3) with permanent magnets (6) located in recesses located on the inner surfaces of cylindrical sleeves (3), are mounted on the shaft (1), where the flanges (3a) of the sleeves (3) are located in the chambers formed by the adjacent pole pieces (4) separated by permanent magnets (5), and the outer conical surfaces of the flanges (3a) of the flange sleeves (3) and the inner conical surfaces of the pole pieces (4) form gaps converging with an angle of inclination (?) in addition on the outer after sealing lips are made on the cylindrical faces of the sleeves (3).
