Thus, adopt the structural type that flange plate and housing are separated, improved largely the utilization ratio of magnetic fluid seal, make magnetic fluid seal can more be applicable to other occasions, during use, only need to change the flange plate of different sizes, just can accomplish one multiplex.
In some embodiments, between the first pole shoe and flange plate, be bolted.Thus, guarantee the coaxality of the first pole shoe and flange plate, can reach the effect of pretension simultaneously.
In some embodiments, housing is connected with one end with flange plate, and joint employing is threaded.。Thus, guarantee the coaxality of housing and the first pole shoe and flange plate.
In some embodiments, adopt copper backing to carry out edge seal between the first pole shoe and flange plate, one end that flange plate is not adjacent with the first pole shoe adopts copper backing to carry out edge seal.Thus, first the edge seal of flange plate and the first pole shoe has guaranteed sealability between the two, and next has guaranteed the coaxality between flange plate and the first pole shoe; Edge seal between flange plate and vacuum end, has better guaranteed the sealability between flange and vacuum chamber.The employing of edge seal, has improved the vacuum-resistant degree ability of the utility model structure greatly, can be applied to ultrahigh vacuum seal.
In some embodiments, between the first pole shoe, the second pole shoe and housing, adopt rubber "O"-ring to realize static seal.Thus, guaranteed sealing.
In some embodiments, on transmission shaft, between clutch shaft bearing and the second bearing, be provided with one first boss; One end end face periphery that the second pole shoe is not adjacent with permanent magnet is provided with annular second boss; Housing is provided with annular the 3rd boss away from one end inwall of flange plate.Thus, be conducive to the installation of bearing and in the adjustment of axial position.
In some embodiments, clutch shaft bearing and the second bearing are angular contact ball bearing.Thus, make transmission shaft axial position fine-tuning.
In some embodiments, the first boss, the second boss and the 3rd boss form the play adjusting space of clutch shaft bearing and the second bearing.
In some embodiments, the axial position of transmission shaft is adjustable.
Separable flange-type device for sealing magnetic fluid of the present utility model compared with prior art, have the following advantages: separable flange-type device for sealing magnetic fluid of the present utility model, the structural type that employing separates flange plate and housing, improved largely the utilization ratio of magnetic fluid seal, make magnetic fluid seal can more be applicable to other occasions, during use, only need to change the flange plate of different sizes, just can accomplish one multiplex.
