Abstract
Hybrydowe uszczelnienie elementów o ruchu obrotowym lub posuwisto-zwrotnym, zawiera zabudowane w komorze dławnicowej pomiędzy wałem lub tłoczyskiem (1), a obudową (2): tuleję kołnierzową (4) wyposażoną w kołnierz (4a) skierowany w stronę wału lub tłoczyska (1), miękkie pierścienie uszczelniające (8), dławik wewnętrzny (9), dławik zewnętrzny (3), walcowe magnesy trwałe (5) spolaryzowane osiowo, wielokrawędziowe nabiegunniki (6) i ciecz magnetyczną (7). Końce tulei kołnierzowej (4) umieszczone są w wytoczeniach wykonanych w dławiku wewnętrznym (9) i w dławiku zewnętrznym (3), a ponadto tuleja (4) zaopatrzona jest w walcowe magnesy trwałe (5), osadzone w otworach wykonanych w kołnierzu (4a) i rozmieszczone równomiernie na jej obwodzie. Po obu stronach kołnierza (4a), do jego powierzchni bocznych przylegają wielokrawędziowe nabiegunniki (6), do których przylegają miękkie pierścienie uszczelniające (8), a do nich: dławik wewnętrzny (9), umieszczony na dnie komory dławnicowej oraz dławik zewnętrzny (3), zamykający komorę od strony otoczenia. Ciecz magnetyczna (7) znajduje się w pierścieniowych szczelinach, utworzonych pomiędzy występami uszczelniającymi wielokrawędziowych nabiegunników (6), a powierzchnią wału lub tłoczyska (1).Hybrid sealing of elements with rotary or reciprocating movement, including built in the stuffing box between the shaft or piston rod (1) and the housing (2): a flange bushing (4) equipped with a flange (4a) facing the shaft or piston rod (1) , soft sealing rings (8), internal gland (9), external gland (3), cylindrical permanent magnets (5) axially polarized, multi-edge pole pieces (6) and magnetic fluid (7). The ends of the flange sleeve (4) are placed in the grooves made in the internal gland (9) and in the external gland (3), and the sleeve (4) is equipped with cylindrical permanent magnets (5), embedded in the holes made in the flange (4a) and evenly distributed around its perimeter. On both sides of the flange (4a), its lateral surfaces are joined by multi-edge pole shoes (6), to which soft sealing rings (8) adhere, and to them: an internal gland (9) located at the bottom of the stuffing box and an external gland (3) closing the chamber from the surroundings. The magnetic fluid (7) is located in the annular gaps formed between the sealing lips of the multi-edge pole pieces (6) and the surface of the shaft or piston rod (1).
