Abstract

Wielostopniowe uszczelnienie odśrodkowe z cieczą magnetyczną, zawierające tuleję kołnierzową, wielokrawędziowy nabiegunnik, magnesy trwałe spolaryzowane promieniowo i ciecz magnetyczną, charakteryzuje się tym, że we wnękach utworzonych pomiędzy pierścieniowymi wytoczeniami, wykonanymi na obwodowych, zewnętrznych częściach powierzchni bocznych kołnierza (3a) tulei kołnierzowej (3), a wewnętrzną, cylindryczną powierzchnią wielokrawędziowego nabiegunnika (4) o przekroju poprzecznym prostokątnym, osadzonego na kołnierzu (3a) tulei kołnierzowej (3), umieszczone są magnesy trwałe (5) ustawione biegunami jednoimiennymi względem powierzchni wału (1). Na bocznych powierzchniach wielokrawędziowego nabiegunnika (4) oraz na powierzchniach bocznych kołnierza (3a) tulei kołnierzowej (3), poniżej magnesów wykonane są występy uszczelniające, zaś ciecz magnetyczna (6) znajduje się w szczelinach osiowych (δa), utworzonych pomiędzy występami uszczelniającymi wielokrawędziowego nabiegunnika (4) i kołnierza (3a) tulei kołnierzowej (3), a powierzchniami bocznymi gniazda obudowy (2) oraz pokrywy (7).A multi-stage centrifugal seal with a magnetic liquid, containing a flange sleeve, a multi-edge pole piece, radially polarized permanent magnets and a magnetic liquid, is characterized by the fact that in the cavities formed between the annular bores made on the peripheral, outer parts of the side surfaces of the flange (3a) the flange sleeve (3 ), and on the inner, cylindrical surface of the multi-edge pole piece (4) with a rectangular cross-section, mounted on the flange (3a) of the flange sleeve (3), permanent magnets (5) are placed with the same poles relative to the surface of the shaft (1). On the side surfaces of the multi-edge pole piece (4) and on the side surfaces of the flange (3a) of the flange sleeve (3), below the magnets, there are sealing projections, and the magnetic fluid (6) is located in the axial slots (δa) formed between the sealing projections of the multi-edge pole piece (4) and flange (3a), flange sleeve (3), and the side surfaces of the housing seat (2) and cover (7).
