Description
Technical field
The utility model relates to a kind of mechanical seal, in particular to a kind of New corrugated pipe mechanical seal belongs to mechanical close
Encapsulation technique field.
Background technique
Existing bellows mechanical seal is workalike sealing, exists in the practice of particular customer scene and asks
Topic, is easy to produce leakage, since mechanical equipment is bigger, it is difficult to guarantee running smoothly for equipment, mechanical seal is caused to be easy to let out
Dew, runing time is short, and this bellows mechanical seal is mounted on axis, is coaxially run together, the gap very little between axis,
Almost without the no enough spaces of formation are swung.
Utility model content
The purpose of this utility model is to provide a kind of New corrugated pipe mechanical seals, to solve to mention in above-mentioned background technique
Out without enough spaces swing the problem of.
To achieve the above object, the utility model provides the following technical solutions: a kind of New corrugated pipe mechanical seal, including
Stationary seat, the stationary seat are fixedly connected by stationary ring anti-rotation pin with stationary ring, and the stationary ring is fixedly mounted on the axle sleeve of shaft
On, the stationary ring is fixedly connected by metal bellows with rotating ring, and one end of the rotating ring is fixed with rotating ring anti-rotation pin.
As a kind of optimal technical scheme of the utility model, the inner wall of the rotating ring open up it is fluted, in the groove
It is fixed with sealing ring, and sealing ring fits with rotating ring.
As a kind of optimal technical scheme of the utility model, the material of the stationary ring and rotating ring is silicon carbide material.
As a kind of optimal technical scheme of the utility model, the material of the metal bellows is stainless steel material.
Compared with prior art, the utility model has the beneficial effects that a kind of New corrugated pipe machinery of the utility model is close
Envelope, original metal bellows mechanical seal design no longer adopt, change the design structure of bellows mechanical seal, have and existed originally
Dynamic group parts in equipment are changed to the quiet group parts in equipment；Change positioning transmission, be fixed on axis by positioning screw be changed to by
Pin is fixed on stationary seat；Stationary ring is designed to that present dynamic group parts, the kind of drive are constant by original quiet group；Design changes
Afterwards, the gap between metal bellows and axis increases, and has enough swing spaces, since the self-swinging of metal bellows is excellent
It is good, and have enough swing spaces, substantially increase the sealing effect and service life of mechanical seal；And driving is firm, fortune
More stable, the long service life of row.
Detailed description of the invention
Fig. 1 is the utility model positive structure schematic.
In figure: 1, shaft；2, stationary seat；3, stationary ring；4, stationary ring anti-rotation pin；5, metal bellows；6, rotating ring；7, rotating ring
Anti-rotation pin.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Referring to Fig. 1, the utility model provides a kind of New corrugated pipe mechanical seal, including stationary seat 2, stationary seat 2
It is fixedly connected by stationary ring anti-rotation pin 4 with stationary ring 3, stationary ring 3 is fixedly mounted on the axle sleeve of shaft 1, and stationary ring 3 passes through metal wave
Line pipe 5 is fixedly connected with rotating ring 6, and one end of rotating ring 6 is fixed with rotating ring anti-rotation pin 7.
Preferably, the inner wall of rotating ring 6 opens up fluted, sealing ring is fixed in groove, and sealing ring is affixed with rotating ring 6
Close, sealing ring is used for being sealed at rotating ring 6 and the joint gap of shaft 1, thus make internal liquid will not driven torus 6 and
It is flowed out at gap between shaft 1.
Preferably, the material of stationary ring 3 and rotating ring 6 is silicon carbide material, the density of silicon carbide material is low, corrosion resistance and
Thermal performance is good, coefficient of friction is low, and in friction surface generation, friction is small when relatively rotating between stationary ring 3 and rotating ring 6, from
And it reduces because the phenomenon that friction causes stationary ring 3 and rotating ring 6 to be damaged is transporting rotating ring 6 in addition, the hardness of silicon carbide material is very high
Not cracky in dynamic process.
Preferably, the material of metal bellows 5 is stainless steel material, and stainless steel material is with corrosion-resistant, hardness is good, rigidity
The feature of good and certain elasticity.
When specifically used, a kind of New corrugated pipe mechanical seal of the utility model, by the metal bellows mechanical seal set
In shaft 1, when shaft 1 rotates, rotary shaft 1 is rotated with dynamic and static ring 3, to drive metal bellows 5 to rotate, 3 He of stationary ring
Relative motion is formed between rotating ring 6, and under elastic force effect of the metal bellows along its axial direction, between stationary ring 3 and rotating ring 6
It fits closely, forms sealing surface to realize sealing.
