Abstract
Uszczelnienie hybrydowe dla wielkogabarytowych elementów o ruchu obrotowym lub posuwisto-zwrotnym, charakteryzuje się tym, że w komorze dławnicowej obudowy (2), zamkniętej obustronnie dławikami (10) znajdują się dwa wielokrawędziowe nabiegunniki (3) w postaci tulei kołnierzowych z występami uszczelniającymi (3c) wykonanymi na wewnętrznych powierzchniach cylindrycznych ich kołnierzy (3a), przedzielone pierścieniowym magnesem trwałym (4). W wytoczeniach (3b) wielokrawędziowych nabiegunników (3), usytuowanych po stronie powierzchni wału lub tłoczyska (1), umieszczone są miękkie pierścienie uszczelniające (6) oraz podzespoły złożone z pierścieni dociskowych (9), sprężyn śrubowych (8) i pierścieni oporowych (7), dociśnięte od zewnątrz dławikami (10), w których osadzone są porowate tulejki ślizgowe (11). W komorze powstałej pomiędzy wewnętrznymi powierzchniami czołowymi kołnierzy (3a) wielokrawędziowych nabiegunników (3), magnesem trwałym (4) i wałem lub tłoczyskiem (1) umieszczony jest dodatkowo pojedynczy miękki pierścień uszczelniający (6). Ciecz magnetyczna (5) znajduje się w pierścieniowych szczelinach (δ), utworzonych pomiędzy występami uszczelniającymi (3c) wielokrawędziowych nabiegunników (3), a powierzchnią wału lub tłoczyska (1).Hybrid seal for large-size elements with rotary or reciprocating motion, characterized by the fact that in the stuffing box chamber of the housing (2), closed on both sides with glands (10), there are two multi-edge pole pieces (3) in the form of flanged sleeves with sealing protrusions (3c). made on the internal surfaces of their cylindrical flanges (3a), separated by an annular permanent magnet (4). Soft sealing rings (6) and components consisting of pressure rings (9), coil springs (8) and stop rings (7) are placed in the grooves (3b) of the multi-edge pole pieces (3), located on the side of the shaft or piston rod (1). ), pressed from the outside with chokes (10), in which porous sliding sleeves (11) are embedded. In the chamber created between the internal faces of the flanges (3a), multi-edge pole pieces (3), the permanent magnet (4) and the shaft or piston rod (1), there is an additional single soft sealing ring (6). The magnetic fluid (5) is located in the annular gaps (δ), formed between the sealing projections (3c) of the multi-edge pole pieces (3) and the surface of the shaft or piston rod (1).
