Summary of the invention: the purpose of this utility model is to provide a kind of working speed to be much higher than the novel high speed magnetic seal transmission device of existing magnetic drive for overcoming the deficiencies in the prior art.
Can realize the purpose of this utility model by following technical proposals, the technical solution that the utility model is taked is as follows: a kind of high speed magnetic seal transmission device, magnet steel rotor assembly in comprising, the outer steel rotor assembly, shielding can, outer bearing carrier and frame cooling water circulation canal is characterized in that: the cooling water circulation canal of described high speed magnetic seal transmission device is by being communicated with the cooling water intake tunnel of cooling water intake to space between shielding can top and the outer steel rotor assembly inwall top, gap and cooling water exhalant canal between outer steel rotor assembly and the shielding can, coolant outlet is connected in series successively together and constitutes.
As further setting of the present utility model: described cooling water intake is arranged on the side of outer bearing carrier flange, the annular lower end surface is provided with outlet, the outer bearing carrier pars intramuralis is provided with the passage that is communicated with described cooling water intake and outlet, be provided with the logical interior or exterior space of groove structure on the described outer steel rotor assembly in the annular region of the corresponding outer bearing carrier annular end face in plane projection thereon, described passage and saturating groove constitute the cooling water intake tunnel, and the frame side wall bottom is provided with open-work and constitutes coolant outlet.
Further be provided with as of the present utility model: described outer steel rotor assembly roof upper and lower surface respectively is provided with the baffle ring that a circle surrounds described annular region projection wherein again, described shielding can top is equipped with protruding splash collar in the outer periphery of described baffle ring, and the root of described splash collar is provided with the saturating groove of some overcurrents.
Further be provided with as of the present utility model: described shielding can cover top edge is provided with the flange that is higher than the surface.
Further be provided with as of the present utility model: be provided with spillway hole on the height and position on the described chassis wall between coolant outlet and the adpting flange.
Compared with prior art, because improvement to the circulation canal of cooling water in the magnetic drive, after cooling water is flowed into from cooling water intake, from high to low successively along outer bearing carrier, the saturating groove of outer steel rotor assembly to the shielding can top, the shielding can outer wall, coolant outlet on the frame flows out at last, can guarantee definitely that cooling water shielding can surface is to its effective cooling; And the setting of described baffle ring and peripheral splash collar can prevent from because of the rotation of outer steel rotor assembly cooling water to be thrown away towards periphery and influences cooling effect, changes thereby can make the rotating speed of magnetic drive be increased to per second nearly 1000, has enlarged application.
