Abstract

Uszczelnienie hybrydowe wielkogabarytowych elementów o ruchu posuwisto-zwrotnym lub obrotowym, ma w komorze dławnicowej obudowy (2) osadzone dwa wielokrawędziowe nabiegunniki (3) w postaci tulei kołnierzowych z występami uszczelniającymi wykonanymi na wewnętrznych powierzchniach cylindrycznych ich kołnierzy (3a), przedzielone pierścieniowym magnesem trwałym (4) spolaryzowanym osiowo, a w podtoczeniach (3b) wielokrawędziowych nabiegunników (3) usytuowanych po stronie tłoczyska (lub wału) (1) umieszczone są symetrycznie położone dwa pakiety uszczelniające, każdy złożony z miękkiego pierścienia uszczelniającego (9) o przekroju prostokątnym oraz co najmniej dwóch magnesów trwałych (5, 6) spolaryzowanych promieniowo, przedzielonych niemagnetycznymi przekładkami (7), przy czym sąsiednie magnesy trwałe (5, 6) ustawione są przemiennie biegunami N i S względem powierzchni tłoczyska(lub wału).Hybrid sealing of large-size elements with reciprocating or rotating motion has two multi-edge pole pieces (3) in the form of flange sleeves with sealing protrusions made on the inner cylindrical surfaces of their flanges (3a), separated by an annular permanent magnet ( 4) axially polarized, and in the undercuts (3b) of the multi-edge pole pieces (3) located on the side of the piston rod (or shaft) (1) there are two symmetrically located sealing packages, each consisting of a soft sealing ring (9) with a rectangular cross-section and at least two radially polarized permanent magnets (5, 6), separated by non-magnetic spacers (7), where the adjacent permanent magnets (5, 6) are alternately positioned with N and S poles relative to the surface of the piston rod (or shaft).
