Abstract
The utility model provides a magnetic grease sealing mechanism which comprises a sealing cavity with a shaft sleeve structure penetrating the center. Two rows of transversely-symmetrical cross-arranged permanent magnets and magnetic poles are arranged at two ends of the periphery of the inner wall of a shaft sleeve, the magnetic poles are provided with cooling water grooves, sealing medium inlets are further formed in the magnetic poles located in the middle, and annular sealing rings are further arranged between the magnetic poles and the sealing cavity. The problem that large magnetic grease power loss caused by temperature rise in the prior art is well solved by adopting the magnetic grease sealing mechanism.
Description
Technical field
The utility model relates to a kind of field of sealing technology, particularly relates to a kind of magnetic fat seal arrangement.
Background technique
Magnetic fluid, as a kind of new function material, has the mobility of liquid and the magnetic of magnetic material simultaneously.Nanometer magnetic fluid sealing (abbreviation magnet fluid sealing) is its one of the most successful practical application, it has, and leakage rate is low, wearing and tearing less, the feature such as simple in structure, long service life.
Because the viscosity of magnetic fat own is higher, under magnetic fields, can produce larger viscous resistance, along with rotating speed raises, in magnetic fat, friction aggravation in magnetic-particle, produces a large amount of heat, and magnetic fat temperature is acutely raise.Simultaneous energy loss, i.e. power loss.
Model utility content
In view of the above, the purpose of this utility model is to provide a kind of magnetic fat sealing mechanism, for solving prior art because temperature rise causes the larger problem of magnetic fat power loss.
For achieving the above object and other relevant objects, the utility model provides following technological scheme:
A kind of magnetic fat sealing mechanism is provided, comprise the Seal cage with the axle sleeve structure that gos deep into center, the peripheral two ends of described sleeve lining are provided with permanent magnet and the magnetic pole that two rows are the mutual cross arrangement of lateral symmetry, on described magnetic pole, offer bosh and be positioned in the middle of magnetic pole also offer sealing medium entrance, between magnetic pole and Seal cage, be also provided with O-ring seal.
Preferably, on the described bosh of described sleeve lining both sides, offer respectively cooling water inlet and cooling water intake.
Preferably, the quantity of the described permanent magnet of described sleeve lining either side is that two, the quantity of described magnetic pole are one.
Preferably, described magnetic pole be positioned at two described in the middle of permanent magnet.
Preferably, described permanent magnet is NdFeB material.
Preferably, described magnetic pole is pure iron.
As mentioned above, the utlity model has following beneficial effect: reduce the temperature rise due to the described generation of friction by begin to cool down tank on magnetic pole, effectively controlled temperature, thereby reduced power consumption.
Accompanying drawing explanation
In order to be illustrated more clearly in the scheme in the utility model embodiment, to accompanying drawing that describe required use in specific embodiment be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those skilled in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present utility model, rather than whole embodiments.Based on embodiment of the present utility model, all other embodiments that those of ordinary skills obtain under the prerequisite of not making creative work, belong to the scope that the utility model is protected.
Please refer to Fig. 1, show the cross-sectional view of the magnetic fat sealing mechanism that the utility model one specific embodiment provides, as shown in the figure, described magnetic fat sealing mechanism comprises the Seal cage 6 with axle sleeve 5 structures of going deep into center, the peripheral two ends of described axle sleeve 5 inwalls are provided with permanent magnet 3 and the magnetic pole 4 that two rows are the mutual cross arrangement of lateral symmetry, on described magnetic pole 4, offer bosh and be positioned in the middle of magnetic pole 4 also offer sealing medium entrance 7, between magnetic pole 4 and Seal cage 6, be also provided with O-ring seal.Described axle sleeve 5 is for being socketed running shaft 1.
Particularly, on the described bosh of described axle sleeve 5 inwall both sides, offer respectively cooling water inlet 8 and coolant outlet 2, the quantity of the described permanent magnet 3 of described axle sleeve 5 inwall either sides is that two, the quantity of described magnetic pole 4 are one, described magnetic pole 4 be positioned at two described in the middle of permanent magnet 3, described permanent magnet 3 is NdFeB material, and described magnetic pole 4 is pure iron.
In sum, the utility model reduces the temperature rise due to the described generation of friction by begin to cool down tank on magnetic pole 4, has effectively controlled temperature, thereby has reduced power consumption.So the utility model has effectively overcome various shortcoming of the prior art and tool high industrial utilization.
