Description
Technical field
The utility model is related to a kind of non-contact mechanical seal device with self-lubricating function, belongs to Sealing Technology neck
Domain.
Background technology
Non-contact mechanical seal offers the dynamic pressure groove of different types on its seal face, is produced when sealing operation
Dynamic pressure effect open seal face, reduce the frictional dissipation between seal face, sealed service life extended, except this
Outside its leakage rate it is low and stability is higher, widely should so non-contact mechanical seal has in fluid mechanical device
With.But with industrial expansion, mechanical seal operating condition is more to be intended to high rotating speed, high temperature and high pressure.With carrying for rotating speed
It is high, although the dynamic pressure effect that end face dynamic pressure groove is produced can strengthen but while serious cavitation phenomenon also occurs, while end face
The rise of temperature can reduce the viscosity of obstruction medium, reduce end face dynamic pressure effect, cause seal face to contact, and increase seal face
Between abrasion, reduce sealed service life.
Utility model content
In consideration of it, the utility model can promote the flowing of the obstruction medium in annular seal space, sealing ring is effectively reduced
Temperature, while ensureing there is complete fluid film always between seal face, enhances the lubricating ability of seal face, extension sealing
Service life.The technical scheme that it is used is as follows：
A kind of self-lubricating non-contact mechanical seal device, the device is by stationary ring (1), pressurized ring (2), rotating seat (3), axle
Cover (4), rotating ring (5), throw-out collar (6), spring (7) composition, it is characterised in that：Described stationary ring is installed in stationary seat, stationary seat
It is fixed on cavity；Spring is connected with throw-out collar, and is positioned in the spring groove in rotating seat；Rotating ring is connected and is positioned over throw-out collar
In rotating seat, it is connected with axle sleeve and is rotated with axle sleeve on the inside of rotating seat, outside is connected with pressurized ring；Pressurized ring passes through anti-rotation groove
Servo-actuated ring seat is rotated.
Described pressurized ring (2) is servo-actuated ring seat (3) synchronous axial system, and carries out pretension, the increasing on pressurized ring to rotating ring
Pressure blade bending direction should be less than 90 degree with rotating shaft direction of rotation.
Offer the honeycomb duct (8) by outer side surface to sealing surface in described rotating ring (5), honeycomb duct cross sectional shape is to have
It is the most important condition beneficial to flow of fluid, and cross-sectional area is gradually reduced, its quantity is corresponded with position with supercharging blade.
The good effect that the utility model has：
When the pressurized ring that the device is used is with axis of rotation, obstruction medium is pressurizeed by being pressurized blade, through leading in rotating ring
Runner enters in seal clearance, provides certain opening force while preventing sealing medium from revealing, separates dynamic and static ring, accelerates
The flowing of obstruction medium, and in seal clearance complete liquid film is formed, the friction between end face can be not only reduced, together
When can reduce sealing ring temperature, extend sealed service life.
