Abstract

Wielostopniowe uszczelnienie wału z zastosowaniem cieczy magnetycznej charakteryzuje się tym, że w pierwszej komorze utworzonej pomiędzy tulejami (3, 4) i kołnierzem (4a) tulei ruchomej (4) osadzone są na zewnętrznej, walcowej powierzchni tulei ruchomej (4) co najmniej dwa pierścieniowe magnesy trwałe, usytuowane przemiennie biegunami N i S względem wału (1) i obudowy (2), przedzielone niemagnetycznymi przekładkami (7) oraz ruchomy wielokrawędziowy nabiegunnik (11), umocowany na końcu tulei ruchomej (4). W drugiej komorze powstałej pomiędzy tulejami (3, 4) i kołnierzem (3a) tulei nieruchomej (3) osadzone są na wewnętrznej, cylindrycznej powierzchni tulei nieruchomej (3) co najmniej dwa pierścieniowe magnesy trwałe, usytuowane przemiennie biegunami N i S względem wału (1) i obudowy (2), przedzielone niemagnetycznymi przekładkami (10) oraz nieruchomy wielokrawędziowy nabiegunnik (12), umocowany na końcu tulei nieruchomej (3). Ciecz magnetyczna (13) znajduje się w pierścieniowych szczelinach (?), utworzonych w obu komorach.The multistage shaft seal using a magnetic liquid is characterized by the fact that in the first chamber formed between the sleeves (3, 4) and the flange (4a) of the movable sleeve (4) are mounted on the outer cylindrical surface of the movable sleeve (4), at least two annular magnets durable, alternating poles N and S relative to the shaft (1) and housing (2), separated by non-magnetic spacers (7) and a movable multi-edge pole piece (11), mounted at the end of the movable sleeve (4). In the second chamber formed between the sleeves (3, 4) and the flange (3a) of the fixed sleeve (3), at least two annular permanent magnets, alternating with N and S poles relative to the shaft (1) are mounted on the inner cylindrical surface of the fixed sleeve (3). ) and housings (2), separated by non-magnetic spacers (10) and a fixed, multi-edge pole piece (12), fixed at the end of the fixed sleeve (3). The magnetic liquid (13) is located in the annular slots (?) Formed in both chambers.
