Abstract
The utility model discloses a kind of improvement sealing mechanism, comprise rotating shaft and housing, in described housing, be provided with bearing and sealing pair, described rotating shaft is successively through bearing and sealing pair, described sealing pair comprises permanent magnet, is arranged on the magnetic pole at permanent magnet two ends and is arranged on the magnetic fluid between described two magnetic poles and described rotating shaft, between described bearing and magnetic pole, be provided with baffle ring, the joint of described housing rotating shaft is provided with seal ring.The sealing configuration of this structure, adopt the compound sealing structure of seal ring sealing and magnet fluid sealing, can reach complete leak free sealing effect, simultaneously, utilize baffle ring to block sealing fluid, can avoid sealing fluid to the washing away of magnetic fluid, avoid magnetic fluid to run off, thereby further guarantee sealing effect, extend the working life of sealing configuration.
Description
Technical field
The utility model relates to sealing configuration, particularly the magnetic fluid sealing structure after a kind of improvement.
Background technique
The application of Magneticfluid Seal Technique in sealing technique is one of its most important achievement, development through decades, magnet fluid sealing is widely applied in various fields such as national defence, space flight, machinery, electronics, instrument, atomic power, chemical industry, pharmacy, and particularly aspect three of dust sealing, vacuum seal and pressure reduction sealings, performance is very outstanding.As the sealing at important machinery rotation position, especially in rotating shaft, the dynamic leakage preventive portion as equipment has outstanding superiority.
There are the following problems when seal fluid for the magnetic fluid sealing structure of prior art: the mutual motion between sealing fluid and magnetic fluid, sealing fluid washes away magnetic fluid, causes magnetic fluid to run off, thereby affects sealing effect.
Model utility content
In view of this, the purpose of this utility model is to provide a kind of improvement sealing configuration, addresses the above problem.
The utility model addresses the above problem by following technological means: a kind of improvement sealing mechanism, comprise rotating shaft and housing, in described housing, be provided with bearing and sealing pair, described rotating shaft is successively through bearing and sealing pair, described sealing pair comprises permanent magnet, is arranged on the magnetic pole at permanent magnet two ends and is arranged on the magnetic fluid between described two magnetic poles and described rotating shaft, between described bearing and magnetic pole, be provided with baffle ring, the joint of described housing rotating shaft is provided with seal ring.
Further, between described baffle ring and magnetic pole, be provided with sealed material layer.
Further, between described sealing pair and housing, be provided with magnetic shield.
The beneficial effects of the utility model: improvement sealing mechanism of the present utility model, comprise rotating shaft and housing, in described housing, be provided with bearing and sealing pair, described rotating shaft is successively through bearing and sealing pair, described sealing pair comprises permanent magnet, is arranged on the magnetic pole at permanent magnet two ends and is arranged on the magnetic fluid between described two magnetic poles and described rotating shaft, between described bearing and magnetic pole, be provided with baffle ring, the joint of described housing rotating shaft is provided with seal ring.The sealing configuration of this structure, adopt the compound sealing structure of seal ring sealing and magnet fluid sealing, can reach complete leak free sealing effect, simultaneously, utilize baffle ring to block sealing fluid, can avoid sealing fluid to the washing away of magnetic fluid, avoid magnetic fluid to run off, thereby further guarantee sealing effect, extend the working life of sealing configuration.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is structural representation of the present utility model.
Embodiment
Below with reference to accompanying drawing, the utility model is elaborated, as shown in Figure 1: a kind of improvement sealing mechanism, comprise rotating shaft 1 and housing 2, in described housing, be provided with bearing 3 and sealing pair, described rotating shaft is successively through bearing 3 and sealing pair, described sealing pair comprises permanent magnet 4, is arranged on the magnetic pole 5 at permanent magnet two ends and is arranged on the magnetic fluid 6 between described two magnetic poles and described rotating shaft, between described bearing and magnetic pole, be provided with baffle ring 7, the joint of described housing rotating shaft is provided with seal ring 8.The sealing configuration of this structure, adopt the compound sealing structure of seal ring sealing and magnet fluid sealing, can reach complete leak free sealing effect, simultaneously, utilize baffle ring to block sealing fluid, can avoid sealing fluid to the washing away of magnetic fluid, avoid magnetic fluid to run off, thereby further guarantee sealing effect, extend the working life of sealing configuration.
As the further improvement of technique scheme, between described baffle ring and magnetic pole, be provided with sealed material layer 9, between flow-stopping plate and magnetic pole, form extruded sealing structure, can further guarantee sealing effect.
Further improvement as technique scheme, is provided with magnetic shield 10 between described sealing pair and housing, leaking in the magnetic field that magnetic shield can completely cut off sealing pair, guarantees the magnetic field of sealing pair, improves magnet fluid sealing effect.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
