Abstract
Uszczelnienie hybrydowe dla elementów o ruchu posuwisto-zwrotnym lub o ruchu obrotowym, ma w komorze dławnicowej obudowy (2) osadzone dwa wielokrawędziowe nabiegunniki (3) w postaci tulei kołnierzowych z występami uszczelniającymi wykonanymi na powierzchniach cylindrycznych ich kołnierzy (3a), przedzielone pierścieniowym magnesem trwałym (4) spolaryzowanym osiowo, a w podtoczeniach (3b) wielokrawędziowych nabiegunników (3) położonych po stronie tłoczyska (lub wału) (1) umieszczone są dwa pakiety uszczelniające, każdy złożony z miękkiego pierścienia uszczelniającego (7) o przekroju prostokątnym oraz magnesu trwałego (5) o przekroju ceowym, którego ramiona skierowane w stronę powierzchni tłoczyska (lub wału) (1) stanowią bieguny N i S, a od strony wewnętrznej magnesu trwałego (5) pomiędzy biegunami N i S umieszczony jest elastyczny pierścień uszczelniający o przekroju kołowym (8) wraz z pierścieniami oporowymi (9). Komora dławnicowa zamknięta jest z obu stron obudowy (2) dławikami (12), w których osadzone są tulejki ślizgowe porowate (13), przylegające do powierzchni tłoczyska (lub wału) (1).A hybrid seal for reciprocating or rotating elements has two multi-edge pole pieces (3) in the form of flanged sleeves with sealing lips made on the cylindrical surfaces of their flanges (3a), separated by an annular permanent magnet. (4) axially polarized, and in the recesses (3b) of multi-edge pole pieces (3) located on the side of the piston rod (or shaft) (1), there are two sealing packages, each consisting of a soft sealing ring (7) with a rectangular cross-section and a permanent magnet (5 ) with a C-section, the arms of which facing the surface of the piston rod (or shaft) (1) constitute the N and S poles, and on the inside of the permanent magnet (5) between the N and S poles there is a flexible O-ring (8) together with the support rings (9). The stuffing box is closed on both sides of the housing (2) with glands (12) in which porous sliding sleeves (13) are mounted, adhering to the surface of the piston rod (or shaft) (1).
