Abstract
The utility model discloses a fan packing seal structure, it relates to fan sealing technique field. It includes elastic ring, sealed packing and recess, the epaxial axle sleeve that has cup jointed, and the axle sleeve outer lane is provided with a plurality of recesses, and the recess cooperatees with elastic ring, and elastic ring sets up at sealed packing inner circle. Elastic ring be a plurality of. Elastic ring adopt 3Cr13, its elasticity is very strong, forces to expand the sealing member that moves the outer lane at the operation in -process and better contacts with the seal receptacle. For strengthening its wear -resisting and self -lubricating property, the outer lane material adopts reinforced plastics CFRP. The utility model discloses simple structure, it is sealed effectual, long service life, the practicality is strong.
Description
Technical field
The utility model relates to blower fan technical field of sealing technology, and in particular to a kind of blower fan expansion ring seale structure.
Background technology
The sealing structure of traditional roots blower, using the self-expanding sealing ring with otch, is that a kind of utilization is blocked and saved
The device that stream principle is sealed, several packings are fitted in the cannelure processed on axle sleeve, and packing relies on the bullet of itself
Power is combined with seal receptacle endoporus, and at the cylindrical position of packing prefastening sealing is formed.Gas can only pass through the seam of packing and cannelure
Gap is downstream revealed, and during work, packing is close to the downstream end face of cannelure in the presence of the gas differential pressure of both sides.Into seam
The gases at high pressure of gap are full of backlash space so that packing is cylindrical and sealing of between seal receptacle endoporus is further strengthened, remaining
Leakage channel only has the otch of packing.But this expansion ring seale structure when in use between it is long after asking for serious wear occurs
Topic, so as to cause gas leakage to bearing housing, leverages normally using for blower fan.
The content of the invention
For deficiency present on prior art, it is to provide a kind of blower fan expansion ring seale knot that this utility model purpose is
Structure, simple structure, good sealing effect, long service life is practical.
To achieve these goals, this utility model is by the following technical solutions realizing：A kind of blower fan packing is close
Seal structure, including elastic force ring, seal expanding ring and groove, are socketed with axle sleeve on axle, axle sleeve outer ring is provided with multiple grooves, groove with
Elastic force ring is engaged, and elastic force ring is arranged on seal expanding ring inner ring.
Preferably, described elastic force ring is multiple.
Preferably, described elastic force ring adopts 3Cr13, its elasticity is very strong, and swollen dynamic outer ring is forced in operation process
Sealing member is more preferably contacted with seal receptacle. and to strengthen its wear-resisting and self-lubricating property, outer loop material adopts reinforced plastics CFRP.
It is of the present utility model effective：Wear-resisting carbon fiber and self-lubricating thing are contained in seal expanding ring of the present utility model
Matter molybdenum bisuphide, so as to substantially increase wearability and self-lubricating property, CFRP materials have wear-resisting, corrosion-resistant, high temperature resistant,
Resistance to expansion, good seal performance the characteristics of noise is low, can strengthen lubrication, thus will substantially reduce the fatigue damage of sealing.And
And after use time length, the phenomenon of gas leakage will not also occur.
Description of the drawings
With reference to the accompanying drawings and detailed description describing this utility model in detail；
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Technological means, creation characteristic, reached purpose and effect to realize this utility model is easy to understand, below
With reference to specific embodiment, this utility model is expanded on further.
With reference to Fig. 1, this specific embodiment is employed the following technical solutions：A kind of blower fan expansion ring seale structure, including elastic force
Ring 1, seal expanding ring 2 and groove 3, are socketed with axle sleeve 4 on axle 5, the outer ring of axle sleeve 4 is provided with multiple grooves 3, groove 3 and elastic force ring 1
It is engaged, elastic force ring 1 is arranged on the inner ring of seal expanding ring 2.
It should be noted that described elastic force ring 1 is multiple.
Additionally, described elastic force ring 1 adopts 3Cr13, its elasticity is very strong, and the sealing of swollen dynamic outer ring is forced in operation process
Part is more preferably contacted with seal receptacle. and to strengthen its wear-resisting and self-lubricating property, outer loop material adopts reinforced plastics CFRP.
Wear-resisting carbon fiber and self-lubricating substances molybdenum bisuphide are contained in the seal expanding ring of this specific embodiment, so as to
Wearability and self-lubricating property are substantially increased, CFRP materials have wear-resisting, corrosion-resistant, high temperature resistant, resistance to expansion, sealing property
Well, the characteristics of noise is low, can strengthen lubrication, thus will substantially reduce the fatigue damage of sealing.And use time length
Afterwards, the phenomenon of gas leakage also will not occur.
Ultimate principle of the present utility model and principal character and advantage of the present utility model has been shown and described above.One's own profession
The technical staff of industry it should be appreciated that this utility model is not restricted to the described embodiments, described in above-described embodiment and description
Simply illustrate principle of the present utility model, on the premise of without departing from this utility model spirit and scope, this utility model is also
Various changes and modifications are had, these changes and improvements are both fallen within the range of claimed this utility model.This utility model
Claimed scope is by appending claims and its equivalent thereof.
