Abstract
Hybrydowe uszczelnienie wału charakteryzuje się tym, że w obudowie (2) osadzona jest tulejka kołnierzowa symetryczna (3), a na wale (1) osadzone są dwie tulejki kołnierzowe niesymetryczne (4) albo w obudowie (2) osadzone są dwie tulejki kołnierzowe niesymetryczne (4), a na wale (1) osadzona jest tulejka kołnierzowa symetryczna (3). Na tulejkach kołnierzowych symetrycznych (3) usytuowane są wielokrawędziowe nabiegunniki (8) w taki sposób, że przylegają obustronnie do ich kołnierzy (3a), a na tulejkach kołnierzowych niesymetrycznych (4) usytuowane są wielokrawędziowe nabiegunniki (7) w taki sposób, że przylegają obustronnie do ich kołnierzy (4a). Kołnierze (3a, 4a) posiadają równomiernie rozłożone otwory, w których umocowane są walcowe magnesy trwałe 5,6 spolaryzowane osiowo. Ciecz magnetyczna (9) znajduje się w pierścieniowych szczelinach (δ) utworzonych pomiędzy występami uszczelniającymi wielokrawędziowych nabiegunników (7 i 8) a odpowiadającymi im zewnętrznymi lub wewnętrznymi powierzchniami walcowymi tulejek kołnierzowych symetrycznych (3) lub tulejek kołnierzowych niesymetrycznych (4).The hybrid shaft seal is characterized by the fact that in the housing (2) there is a symmetrical flange sleeve (3), and on the shaft (1) there are two asymmetric flange sleeves (4) or in the housing (2) there are two asymmetric flange sleeves ( 4), and a symmetrical collar sleeve (3) is mounted on the shaft (1). On symmetrical flange sleeves (3) multi-edge pole pieces (8) are placed in such a way that they adhere to their flanges (3a) on both sides, and on asymmetric flange sleeves (4) multi-edge pole pieces (7) are located in such a way that they adhere on both sides to their flanges (4a). The flanges (3a, 4a) have evenly distributed holes in which cylindrical permanent magnets 5,6, axially polarized, are fixed. The magnetic fluid (9) is contained in the annular gaps (δ) formed between the sealing protrusions of the multi-edge pole pieces (7 and 8) and the corresponding external or internal cylindrical surfaces of the symmetrical flange sleeves (3) or asymmetric flange sleeves (4).
