Abstract
Hybrydowe uszczelnienie wału obrotowego z wykorzystaniem cieczy ferromagnetycznej zawiera tuleję stopniowaną (3), pokrywę stopniowaną (4), magnesy trwałe (5, 6) spolaryzowane osiowo, wielokrawędziowe nabiegunniki, ruchome (7) i nieruchome (8) oraz ciecz ferromagnetyczną (9). W tulei stopniowanej (3), osadzonej na wale obrotowym (1), wykonane jest dolne wytoczenie (3a) i górne wytoczenie (3b), zaś w pokrywie stopniowanej (4), zamocowanej do obudowy (2), wykonane jest dolne gniazdo (4a) i górne gniazdo (4b). Pomiędzy dolnym wytoczeniem (3a), a dolnym gniazdem (4a) zamocowane są dwa wielokrawędziowe nabiegunniki nieruchome (8) przedzielone jednym magnesem trwałym (6), natomiast pomiędzy górnym wytoczeniem (3b), a górnym gniazdem (4b) zamocowane są dwa wielokrawędziowe nabiegunniki ruchome (7) przedzielone drugim magnesem trwałym (5). Ciecz ferromagnetyczna (9) znajduje się w pierścieniowych szczelinach (?), utworzonych pomiędzy występami uszczelniającymi wielokrawędziowych nabiegunników ruchomych (7), a wewnętrzną walcową powierzchnią górnego gniazda (4b) oraz w pierścieniowych szczelinach (?), utworzonych pomiędzy występami uszczelniającymi wielokrawędziowych nabiegunników nieruchomych (8), a zewnętrzną walcową powierzchnią dolnego wytoczenia (3a).A hybrid rotary shaft seal using a ferromagnetic fluid includes a stepped bushing (3), stepped cover (4), axially polarized permanent magnets (5, 6), multi-edge pole shoes, movable (7) and stationary (8) and ferromagnetic fluid (9). In the stepped sleeve (3), mounted on the rotary shaft (1), the lower groove (3a) and the upper groove (3b) are made, while the graded cover (4), attached to the housing (2), the lower socket (4a) ) and upper socket (4b). Between the lower groove (3a) and the lower seat (4a) are fixed two fixed edge pole pieces (8) separated by one permanent magnet (6), while between the upper groove (3b) and the upper seat (4b) fixed two multi-edge movable pole shoes (7) separated by a second permanent magnet (5). The ferromagnetic liquid (9) is located in the annular gaps (?) Formed between the sealing lips of the multi-edge movable pole pieces (7) and the inner cylindrical surface of the upper seat (4b) and in the annular gaps (?) Formed between the sealing lips of the multi-edge fixed pole pieces (?) 8), and the outer cylindrical surface of the lower groove (3a).
