Abstract

Wielostopniowe uszczelnienie walu z zastosowaniem cieczy magnetycznej charakteryzuje sie tym, ze w przestrzeni utworzonej pomiedzy kolnierzem (3a) tulei nieruchomej (3), wewnetrzna powierzchnia walcowa tulei nieruchomej (3) i zewnetrzna powierzchnia walcowa tulei ruchomej (4) umieszczone sa nabiegunniki nieruchome (7), przedzielone magnesami (5), a w przestrzeni utworzonej pomiedzy kolnierzem (4a) tulei ruchomej (4), a zewnetrzna powierzchnia walcowa tulei ruchomej (4) i wewnetrzna powierzchnia walcowa tulei nieruchomej (3) umieszczone sa nabiegunniki ruchome (8), przedzielone równiez magnesami (5), zas wystepy uszczelniajace usytuowane sa na wewnetrznych powierzchniach bocznych nabiegunników (7, 8). W nabiegunnikach nieruchomych (7) umieszczone sa one w poblizu zewnetrznej powierzchni walcowej tulei ruchomej (4), a w nabiegunnikach ruchomych (8) umieszczone sa one w poblizu wewnetrznej powierzchni walcowej tulei nieruchomej (3), zas wierzcholki wystepów dwóch sasiednich nabiegunników (7, 8), przedzielonych magnesami (5) sa skierowane ku sobie. Ciecz magnetyczna (9) znajduje sie w pierscieniowych szczelinach pomiedzy tymi wystepami i przylega do odpowiednich powierzchni walcowych tulei ruchomej (4) i tulei nieruchomej (3).The multistage shaft seal using a magnetic liquid is characterized by the fact that in the space created between the flange (3a) of the fixed sleeve (3), the internal cylindrical surface of the fixed sleeve (3) and the external cylindrical surface of the movable sleeve (4) are fixed pole pieces (7) , separated by magnets (5), and in the space created between the flange (4a) of the movable sleeve (4) and the external cylindrical surface of the movable sleeve (4) and the internal cylindrical surface of the fixed sleeve (3), movable pole pieces (8) are also separated by magnets (5), and the sealing lips are located on the inner side surfaces of the pole pieces (7, 8). In fixed pole pieces (7) they are located near the outer surface of the cylindrical movable sleeve (4), and in movable pole pieces (8) they are located near the inner surface of the cylindrical fixed sleeve (3), and the tops of the protrusions of two neighboring pole pieces (7, 8 ), separated by magnets (5) are facing each other. The magnetic fluid (9) is located in the ring gaps between these protrusions and adheres to the respective cylindrical surfaces of the movable sleeve (4) and the fixed sleeve (3).
