Description
Technical field
The utility model relates to a kind of magnetic mechanical sealing device that improves structural type.
Background technique
For solving the bearing oil in rotating machinerys such as blower fan, pump, steam turbine, gear-box, speed reducer, motor, perhaps in the rotating machinery of carrying oil medium, adopt traditional oil sealing or labyrinth seal or common mechanical sealing to still have not long problem of oil leakage phenomenon and working life, notification number is to have introduced in the Chinese patent literature of CN2083659U a kind ofly to make the sealing surface of rotating ring and stationary ring keep closely contacting with the relative repulsive force that is produced of like pole, to replace the magnetic thrust mechanical seal device of traditional employing pressure spring structure.Notification number is that the Chinese patent literature of CN 2101141U and CN 2367831Y has then been introduced the magnetic mechanical seal and the mechanical seal axle that adopt the polarity effect to make rotating ring and sealing surface between stationary ring keep closely contacting respectively and held protector; its structural type all is that magnetic element is embedded in rotating ring and/or the stationary ring; except that add the fixing of man-hour and in use keep on its long-term adeciduate stability difficult; in the above-mentioned three kinds seal arrangements that replace conventional springs structural type with magnetic texure, make the rotating ring unit keep the tight active force that contacts to have only this single magnetive attraction with sealing surface between the stationary ring unit.The not high and/or less-than-ideal rotating machinery of operating condition for precision, under accidental or unexpected vibration, the shock effect, the situation that still might occur leaking takes place in operation process.
The model utility content
At above-mentioned situation, the utility model will provide a kind of improved magnetic mechanical sealing device, make its mechanical sealing surface can have better freedom from vibration, impact resistance and sealing tracing ability, improve sealing effect, and can reduce the required precision of equipment and be applicable in the less-than-ideal rotating machinery of operating condition.
The improved magnetic mechanical sealing device of the utility model, by being provided with vertically and being that the stationary ring unit and the rotating ring unit of sealing surface and the static seal element of going up corresponding configuration thereof constitute, between stationary ring unit and rotating ring unit, also be provided with and make its sealing surface keep the tight magnetic compensation structure that contacts with the contact end face that can make relative rotary motion therebetween.Wherein, be provided with between stationary seat in the stationary ring unit and the stationary ring can make stationary ring have can with the sealing surface retainer shaft of rotating ring unit float type second collocation structure to tracing ability contact action power.
Said float type second collocation structure that is arranged in the stationary ring unit can adopt different forms in the said structure, for example, can adopt the structural member of the elastic seal ring form that is embedded between stationary seat and the stationary ring, utilize it to insert tracing ability is realized in the back because of the axial elasticity restoring force that compressive strain produced floating compensation.In addition, based on principle of uniformity, this float type second collocation structure also can be adopted as the member of form of springs, or the structural member of other appropriate format.
In said structure, in the said rotating ring unit with stationary ring with the said structural member that end face is a sealing surface that contacts of making relative rotary motion, both can be the rotating ring unit of overall structure form, also can be the rotating ring member that is arranged at rotating seat corresponding end-faces position with mosaic mode.
The set-up mode of said magnetic compensation structure also can adopt various ways in the said structure.For example, making this magnetic compensation structure is to be arranged in the rotating ring unit the magnetic texure body of arranging along the ring-type form of discontinuity on the rotating seat or the magnet ring structure of whole conitnuous forms, and make corresponding with its magnetic action power and make corresponding construction that said sealing surface keeps closely contact for having ferromagnetic stationary ring unit member, be exactly a kind of in alternative structural type.In this structure, saidly be arranged at the magnetic compensation structure on the rotating seat in the rotating ring unit and generally be embedded at form on the rotating seat for well to be adopted as staircase structural model through axially being provided with on the rotating seat, manufacturing and maintenance both be convenient to, can effectively prevent magnetic compensation structure coming off in use again, prolong working life.Said in the structure have ferromagnetic stationary ring unit member with corresponding this of magnetic action power that is arranged at the magnetic compensation structure in the rotating ring unit, can be for having ferromagnetic stationary ring in the stationary ring unit member, also can be for having ferromagnetic stationary seat and/or being this stationary ring whole unit structure.
Except that above-mentioned form, the set-up mode that makes said magnetic compensation structure is the magnet ring structure that is arranged in the stationary ring unit, and make corresponding with its magnetic action power and make corresponding construction that said sealing surface keeps closely contact for having ferromagnetic rotating ring unit member, be another kind of alternative structural type.Said herein be arranged at the corresponding rotating ring unit member of magnetic action power of the magnetic compensation structure in the stationary ring unit, generally can be for having the ferromagnetic rotating seat or the integral body of rotating ring unit.
Because above-mentioned magnetic mechanical sealing device of the present utility model is on the architecture basics of existing magnetic mechanical sealing device, in the stationary ring unit, add the stationary ring that can make wherein and in the axial direction rotating ring has been made float type second collocation structure of tracing ability motion, thereby under in use the chance or fortuitous event, can be to making by single magnetic force, sealing surface between the stationary ring unit keeps the deficiency of closely contact to give adequate compensation, make sealing surface can have better freedom from vibration, performance is followed in impact resistance and sealing, can greatly improve sealing effect, and can reduce using the required precision of equipment, also more can be applicable in the less-than-ideal rotating machinery of operating condition.
Below again foregoing of the present utility model is described in further detail by embodiment by the accompanying drawing example illustrated, but this should be interpreted as that the scope of the above-mentioned theme of the utility model only is confined to following instantiation.All technology that is realized based on the utility model foregoing all belong to scope of the present utility model.
