Abstract

Przedmiotem zgłoszenia jest hybrydowe uszczelnienie dławnicowe wału, stosowane do uszczelniania wałów obrotowych w maszynach i urządzeniach. Hybrydowe uszczelnienie dławnicowe wału posiada w obudowie (2), pomiędzy miękkimi pierścieniami uszczelniającymi (3), wielokrawędziowy nabiegunnik (4), oddzielony od miękkich pierścieni uszczelniających (3) przekładkami niemagnetycznymi (8), w którym wykonane są zewnętrzne wnęki pierścieniowe (4a), usytuowane po stronie obudowy (2), oraz wewnętrzne wnęki pierścieniowe (4b), położone po stronie wału (1), dzięki czemu w wielokrawędziowym nabiegunniku (4), powstały kołnierze zewnętrzne (4c), usytuowane po stronie obudowy (2), oraz kołnierze wewnętrzne (4d), położone po stronie wału (1), zaś w zewnętrznych wnękach pierścieniowych (4a), wielokrawędziowego nabiegunnika (4), umieszczone są magnesy trwałe (5, 6), które przylegają do powierzchni bocznych środkowego kołnierza zewnętrznego (4c), biegunami jednoimiennymi N-N, a na walcowych powierzchniach zewnętrznych kołnierzy (4c), wielokrawędziowego nabiegunnika (4), po stronie obudowy (2), umieszczone są w gniazdach elastyczne pierścienie uszczelniające (13), typu „O”, a na cylindrycznych powierzchniach wewnętrznych kołnierzy (4d), wielokrawędziowego nabiegunnika (4), po stronie wału (1), wykonane są występy uszczelniające, zaś w szczelinach promieniowych (dr) utworzonych pomiędzy występami uszczelniającymi wielokrawędziowego nabiegunnika (4), a wałem (1) znajduje się ciecz magnetyczna (7), zaś w komorze dławnicowej w obudowie (2), na końcu pakietu uszczelniającego po stronie zewnętrznej, umieszczony jest pierścień dociskowy (9), oraz dławik (10), a we wnękach wykonanych na powierzchniach czołowych pierścienia dociskowego (9) i dławika (10), osadzone są magnesy trwałe (11, 12) spolaryzowane osiowo i usytuowane względem siebie biegunami jednoimiennymi N-N.The subject of the application is a hybrid shaft packing used for sealing rotary shafts in machines and devices. The hybrid shaft seal in the casing (2), between the soft sealing rings (3), has a multi-edge pole piece (4), separated from the soft sealing rings (3) by non-magnetic spacers (8), in which the outer ring cavities (4a) are made, on the side of the casing (2), and internal annular recesses (4b) on the side of the shaft (1), thanks to which outer flanges (4c) on the side of the casing (2) and flanges are formed in the multi-edge pole piece (4). internal (4d), located on the shaft side (1), and in the outer annular recesses (4a) of the multi-edge pole piece (4), permanent magnets (5, 6) are placed, adhering to the side surfaces of the central outer flange (4c), with homonymous poles LV, and on the cylindrical outer surfaces of the flanges (4c), multi-edge pole piece (4), on the housing side (2), there are elastic rings on the sockets sealing (13), "O" type, and on the cylindrical inner surfaces of the flanges (4d) of the multi-edge pole piece (4), on the shaft side (1), sealing lips are made, and in the radial gaps (dr) formed between the sealing lips of the multi-edge the pole piece (4), and the shaft (1) contains a magnetic fluid (7), and in the stuffing box in the casing (2), at the end of the sealing package on the outer side, there is a pressure ring (9) and a gland (10), and in the cavities made on the faces of the pressure ring (9) and the choke (10), permanent magnets (11, 12), axially polarized and positioned with respect to each other with homonymous NN poles, are mounted.
