Hybrid sealing of rotary shaft with magnetic liquid

摘要

hybrid seal shaft torque, in which the rotary shaft (1) is embedded kou0142nierzowa sleeve (3), which in turn are recessed, annular permanent magnets (4, 5), the adjacent n and s poles ru00f3u017cnoimiennymi surface side flange (3a) and wielokrawu0119dziowe nabi egunniki movable (6) located at their external surfaces of sealing performances walcowych.on the external cylindrical part (3) kou0142nierzowej cores are made prawoskru0119tne helical grooves (11), located on the side of the working chamber, a factor uszczelnianym (13). kou0142nierzowa sleeve (3) with pieru015bcieniowymi permanent magnets (4, 5) and wielokrawu0119dziowymi nabiegunnikami mobile (6) is placed in a housing (2) within the chamber du0142awnicowej, the closed lid (7).in the front cover (7) are positioned cylindrical permanent magnets (8), and both side surface partitions adjacent wielokrawu0119dziowe nabiegunniki immovable (9).magnetic fluid (10) located in the annular slits (6) formed between the sealing performances wielokrawu0119dziowych nabiegunniku00f3w mobile (6),and the inner surface walcowu0105 chamber du0142awnicowej in a housing (2) and (6) in the apertures of the annular sealing wielokrawu0119dziowych between performances nabiegunniku00f3w fixed (9) and the outer surface walcowu0105 cores kou0142nierzowej (3) located on the side of environment.
