Abstract
The utility model proposes a kind of Magnetic oil seal device, including stationary ring one, stationary ring two, rotating ring, permanent magnet and sealing ring, seal to form a section for U-shaped groove between the stationary ring one and stationary ring two by the first O-ring, the stationary ring one is by the 3rd O-ring on equipment；, in U-shaped groove, the rotating ring is by the second O-ring in rotating shaft for the rotating ring；One side fixed permanent magnet and sealing ring that the stationary ring two is contacted with rotating ring, the sealing ring are brought into close contact rotating ring by the magneticaction of permanent magnet and rotating ring.The power that the utility model rotating ring is brought into close contact with sealing ring is invisible magnetic force, does not interfere with spatial rotational, and rotating ring nor affects on sealing effectiveness with rotating shaft bounce.Simple structure, reliable, easy for installation, life-span length.
Description
Technical field
The utility model is related to a kind of Magnetic oil seal device.
Background technology
Multistage centrifugal blower is widely used in environmental protection industry (epi), and the oil sealing of this kind of air blast is constantly updating always
In, with the application of new material and new technology, oil sealing has various designs, traditional lip packing product in the application must
So rub with axial plane, easily fail in the application.Oily not contaminated, working life inside bearing box cannot effectively be prevented
General very short and be difficult to control to.When lip envelope leakage, the loss of lubricating oil will bring catastrophic consequence to bearing and equipment.Axle
Heavy wear caused by equipment damage, rehabilitation cost will necessarily be increased.The oil sealing of other forms, some high costs, has
Complex structure, some sealing effectiveness are bad, etc. during reason causes oil sealing updating always.
Utility model content
The utility model proposes a kind of Magnetic oil seal device, solves traditional oil sealing coefficient of friction greatly, to axle serious wear,
Effectively sealing life is short, and heat resistance is low, and material is easily aging, the problems such as oil sealing tracing ability difference.
The utility model is realized particular by technical scheme below：
A kind of Magnetic oil seal device, including stationary ring one, stationary ring two, rotating ring, permanent magnet and sealing ring, the stationary ring one and quiet
Seal to form a section for U-shaped groove between ring two by the first O-ring, the stationary ring one is arranged on by the 3rd O-ring
On equipment；, in U-shaped groove, the rotating ring is by the second O-ring in rotating shaft for the rotating ring；The stationary ring two with dynamic
The one side fixed permanent magnet and sealing ring of ring contact, the sealing ring are brought into close contact by the magneticaction of permanent magnet and rotating ring
Rotating ring.
Preferably, the stationary ring one is provided with spill port, and the spill port is communicated to U-shaped groove.
What the utility model was produced has the beneficial effect that：Use magnetic technique in the design, theory is sealed using machine, full floating is close
Cover strcution, overall structure are simple, and easy for installation, power consumption is few, and dynamic and static ring friction is consumed less, and sound ring combined face is protected all the time
Close contact is held, even if under larger axle bounce, also can achieve effectively to seal, which substitutes the sealing of other forms, is rotating shaft
The inevitable direction of Sealing Technology development.
Description of the drawings
In order to be illustrated more clearly that the utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or accompanying drawing to be used is briefly described needed for description of the prior art, it should be apparent that, drawings in the following description are only
It is some embodiments of the present utility model, for those of ordinary skill in the art, in the premise for not paying creative work
Under, can be with according to these other accompanying drawings of accompanying drawings acquisition.
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Embodiment in based on the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
A kind of Magnetic oil seal device as shown in Figure 1, including stationary ring 1, stationary ring 22, rotating ring 3, permanent magnet 4 and sealing ring 5,
A section is formed for U-shaped groove by the sealing of the first O-ring 7 between the stationary ring 1 and stationary ring 22, the stationary ring 1 leads to
Cross the 3rd O-ring 6 to be arranged on equipment；In U-shaped groove, the rotating ring 3 is arranged on the rotating ring 3 by the second O-ring 8
In rotating shaft；One side fixed permanent magnet 4 and sealing ring 5 that the stationary ring 22 is contacted with rotating ring 3, the sealing ring 5 pass through permanent magnetism
The magneticaction of body 4 and rotating ring 3 is brought into close contact rotating ring 3.
In the utility model, stationary ring 1 is provided with spill port, and the spill port is communicated to U-shaped groove, reduces the heap of oil
Product.The power that rotating ring 3 is brought into close contact with sealing ring 5 is invisible magnetic force, does not interfere with spatial rotational, and rotating ring also can with axle bounce
Ensure and stationary ring 1 is sealed, do not affect integral sealing effect, simple structure is reliable, easy for installation, life-span length.
Preferred embodiment of the present utility model is the foregoing is only, not in order to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements that is made etc. should be included in the utility model
Protection domain within.
