Abstract
Uszczelnienie dławnicowe z cieczą magnetyczną, zawierające pierścienie oporowe dolny i górny, co najmniej jeden wielokrawędziowy nabiegunnik, pierścieniowe magnesy trwałe spolaryzowane osiowo i ciecz magnetyczną charakteryzuje się tym, że wewnątrz komory dławnicowej w obudowie (2), zamkniętej od góry dławikiem (9), umieszczone są dolny pierścień oporowy (4) i górny pierścień (5) oporowy oraz co najmniej jeden wielokrawędziowy nabiegunnik (3) w kształcie stopniowanej tulejki. Nabiegunnik (3) wyposażony jest w górnej części w walcowe wytoczenie po stronie elementu uszczelnianego (1) i w walcowy występ (3a) po stronie obudowy (2), a w dolnej części wyposażony jest w walcowe wytoczenie po stronie obudowy (2) i w walcowy występ (3a) po stronie elementu uszczelnianego (1). Gdy nabiegunników (3) jest więcej niż jeden, są one połączone ze sobą na zakładkę" poprzez wytoczenia nabiegunników (3) usytuowanych po strome elementu uszczelnianego (1), dopasowanych do walcowych występów (3a) sąsiednich nabiegunników (3) usytuowanych po stronie elementu uszczelnianego (1) i w wytoczenia nabiegunników (3) usytuowanych po stronie obudowy (2), dopasowanych do walcowych występów (3b) sąsiednich nabiegunników (3) usytuowanych po stronie obudowy (2)."Gland seal with magnetic fluid, containing lower and upper retaining rings, at least one multi-edge pole piece, axially polarized permanent ring magnets and magnetic fluid, is characterized by the fact that inside the stuffing box in the casing (2), closed from the top with a gland (9), there are a lower retaining ring (4) and an upper retaining ring (5) and at least one multi-edge pole piece (3) in the shape of a stepped sleeve. The pole piece (3) is equipped in the upper part with a cylindrical bore on the side of the sealed element (1) and with a cylindrical projection (3a) on the casing side (2), and in the lower part it is equipped with a cylindrical bore on the casing side (2) and with a cylindrical projection ( 3a) on the side of the sealed element (1). When there is more than one pole pieces (3), they are connected to each other with an "overlap" by the grooves of the pole pieces (3) located on the side of the sealed element (1), matched to the cylindrical projections (3a) of the adjacent pole pieces (3) located on the side of the sealed element (1) and into the bores of the pole pieces (3) located on the housing side (2), matching the cylindrical projections (3b) of the adjacent pole pieces (3) located on the housing side (2).”
