Abstract
The invention discloses a kind of New corrugated pipe mechanical seals, including stationary seat, stationary seat is fixedly connected by stationary ring anti-rotation pin with stationary ring, stationary ring is fixedly mounted on the axle sleeve of shaft, stationary ring is fixedly connected by metal bellows with rotating ring, a kind of New corrugated pipe mechanical seal of the present invention, and original metal bellows mechanical seal design no longer adopts, the design structure for changing bellows mechanical seal, has the dynamic group parts originally in equipment to be changed to the quiet group parts in equipment；Change positioning transmission, is fixed on to be changed on axis by positioning screw and is fixed on stationary seat by pin；Stationary ring is designed to that present dynamic group parts, the kind of drive are constant by original quiet group；After design changes, the gap between metal bellows and axis increases, and has enough swing spaces, since the self-swinging of metal bellows is excellent, and has enough swing spaces, substantially increases the sealing effect and service life of mechanical seal.
Description
Technical field
The present invention relates to a kind of mechanical seal, in particular to a kind of New corrugated pipe mechanical seal belongs to mechanical seal skill
Art 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.
Summary of the invention
It is mentioned above in the background art to solve the purpose of the present invention is to provide a kind of New corrugated pipe mechanical seal
There is no the problem of enough spaces swing.
To achieve the above object, the invention provides the following technical scheme: a kind of New corrugated pipe mechanical seal, including stationary ring
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, institute
It states stationary ring and is fixedly connected by metal bellows with rotating ring, one end of the rotating ring is fixed with rotating ring anti-rotation pin.
As a preferred technical solution of the present invention, the inner wall of the rotating ring opens up fluted, fixation in the groove
Equipped with sealing ring, and sealing ring fits with rotating ring.
As a preferred technical solution of the present invention, the material of the stationary ring and rotating ring is silicon carbide material.
As a preferred technical solution of the present invention, the material of the metal bellows is stainless steel material.
Compared with prior art, the beneficial effects of the present invention are: a kind of New corrugated pipe mechanical seal of the present invention, original
Metal bellows mechanical seal design no longer adopts, and changes the design structure of bellows mechanical seal, has originally in equipment
Dynamic group parts are changed to the quiet group parts in equipment；Change positioning transmission, is fixed on to be changed on axis by positioning screw and be fixed by pin
On stationary seat；Stationary ring is designed to that present dynamic group parts, the kind of drive are constant by original quiet group；After design changes, metal
Gap between bellows and axis increases, and has enough swing spaces, since the self-swinging of metal bellows is excellent, and has
Enough swing spaces substantially increase the sealing effect and service life of mechanical seal；And driving is firm, operation is more stable,
Long service life.
Detailed description of the invention
Fig. 1 is positive structure schematic of the present invention.
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
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Referring to Fig. 1, the present invention provides a kind of New corrugated pipe mechanical seal, including stationary seat 2, stationary seat 2 pass through
Stationary ring anti-rotation pin 4 is fixedly connected with stationary ring 3, and stationary ring 3 is fixedly mounted on the axle sleeve of shaft 1, and stationary ring 3 passes through metal bellows
5 are 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, which is covered and is being turned by a kind of New corrugated pipe mechanical seal of the present invention
On axis 1, when shaft 1 rotates, rotary shaft 1 is rotated with dynamic and static ring 3, to drive metal bellows 5 to rotate, stationary ring 3 and rotating ring 6
Between form relative motion, it is close between stationary ring 3 and rotating ring 6 and under elastic force effect of the metal bellows along its axial direction
Fitting forms sealing surface to realize sealing.
