Abstract

Uszczelnienie hybrydowe dla elementów o ruchu obrotowym lub posuwisto-zwrotnym, ma w środkowej części komory dławnicowej w obudowie (2) umieszczone uszczelnienie, złożone z wielokrawędziowego nabiegunnika (4) o przekroju prostokątnym oraz dwóch wielokrawędziowych nabiegunników kątowych (5), przedzielonych pierścieniowymi magnesami trwałymi (3), które przylegają do bocznych powierzchni wielokrawędziowego nabiegunnika (4) biegunami jednoimiennymi N. Komora dławnicowa obudowy (2), zamknięta jest z obu stron dławikami (11), w których osadzone są panewki ślizgowe (14), przylegające do powierzchni wału lub tłoczyska (1). W pierścieniowych gniazdach powstałych pomiędzy bocznymi powierzchniami wielokrawędziowego nabiegunnika (4) wielokrawędziowych nabiegunników kątowych (5) oraz wewnętrznymi powierzchniami cylindrycznymi pierścieniowych magnesów trwałych (3) i powierzchnią wału lub tłoczyska (1), umieszczone są elastyczne pierścienie uszczelniające (7) o przekroju kołowym. Ciecz magnetyczna (6) znajduje się w pierścieniowych szczelinach (δ), utworzonych pomiędzy występami uszczelniającymi, usytuowanymi na wewnętrznych cylindrycznych powierzchniach wielokrawędziowego nabiegunnika (4) oraz w pierścieniowych szczelinach (δ) utworzonych pomiędzy występami uszczelniającymi, wykonanymi na wewnętrznych cylindrycznych powierzchniach kołnierzy (5a) wielokrawędziowych nabiegunników kątowych (5), a powierzchnią wału lub tłoczyska (1).Hybrid seal for elements with rotary or reciprocating movement, has a seal placed in the central part of the stuffing box in the housing (2), consisting of a multi-edge pole piece (4) with a rectangular cross-section and two multi-edge angular pole pieces (5), separated by ring permanent magnets ( 3), which adhere to the side surfaces of the multi-edge pole piece (4) with single-name poles N. The stuffing box of the housing (2) is closed on both sides with glands (11), in which sliding bushes (14) are mounted, adhering to the surface of the shaft or piston rod (1). Flexible sealing rings (7) with a circular cross-section are placed in the ring sockets formed between the side surfaces of the multi-edge pole piece (4), multi-edge angle pole pieces (5) and the internal cylindrical surfaces of the ring permanent magnets (3) and the surface of the shaft or piston rod (1). The magnetic fluid (6) is located in the annular gaps (δ) formed between the sealing projections located on the inner cylindrical surfaces of the multi-edge pole piece (4) and in the annular gaps (δ) formed between the sealing projections formed on the inner cylindrical surfaces of the flanges (5a). multi-edge angular pole pieces (5) and the surface of the shaft or piston rod (1).
