Abstract
The utility model discloses a kind of novel single-end face mechanical seal, comprise and be arranged on rotating ring on axle and the sealing surface being arranged at the stationary ring in stationary seat and forming, rotating ring is fixed on axle by rotating ring fixation kit, and arranges rotating ring auxiliary seal ring formation static seal point between rotating ring and axle; Stationary ring is connected with spring assembly by stationary ring fixation kit, and is provided with stationary ring auxiliary seal ring between stationary ring and stationary seat inwall and forms static seal point; It is characterized in that: described sealing ring sealing contact surface has annular recess, in described annular recess, is filled with hair fiber braided ring.The utility model, on the basis of conventional seals circle, sealing ring body sealing contact surface arranges hair fiber braided ring.Utilize large surface tension and the corrosion resistance of hair fiber, considerably increase service life and the sealing effectiveness of sealing ring.After mechanical single seal structural wear, the sealing effectiveness of sealing device can also be ensured, substantially prolongs the service life of mechanical single seal device.
Description
Technical field
The utility model relates to a kind of single mechanical end face seal.
Background technology
Development of Mechanical Seal is to today, more and more diversified, particularly for the technology of single mechanical end face seal, very ripe, applies quite universal in the industrial production, and the common single mechanical end face seal of a lot of occasion just can reach " 0 " and leak.But for some occasion, still there are some problems.
The spring assembly of present single mechanical end face seal, rotating ring, stationary ring all directly contact with material, this brings a lot of impact to the normal operation of mechanical seal, particularly for the material occasion of easy crystallization, existing single mechanical end face seal is difficult to meet the long needs of equipment, wearing and tearing can be caused after using a period of time, cause leakage, the large service life shortening mechanical seal.
Summary of the invention
The utility model object is to provide a kind of long service life for the defect of prior art, the single mechanical end face seal that functional reliability is high.
The utility model for achieving the above object, adopts following technical scheme:
A kind of novel single-end face mechanical seal, comprise and be arranged on rotating ring on axle and the sealing surface being arranged at the stationary ring in stationary seat and form, rotating ring is fixed on axle by rotating ring fixation kit, and arranges rotating ring auxiliary seal ring formation static seal point between rotating ring and axle; Stationary ring is connected with spring assembly by stationary ring fixation kit, and is provided with stationary ring auxiliary seal ring between stationary ring and stationary seat inwall and forms static seal point; It is characterized in that: described sealing ring sealing contact surface has annular recess, in described annular recess, is filled with hair fiber braided ring.
It is further characterized in that: described sealing ring is O shape rubber seal.
The utility model, on the basis of conventional seals circle, sealing ring sealing contact surface arranges hair fiber braided ring.Utilize large surface tension and the corrosion resistance of hair fiber, considerably increase service life and the sealing effectiveness of sealing ring.After mechanical single seal structural wear, the sealing effectiveness of sealing device can also be ensured, substantially prolongs the service life of mechanical single seal device.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is ring structure schematic diagram.
Detailed description of the invention
Single mechanical end face seal as shown in Figure 1, rotating ring 4 is fixed on axle by rotating ring fixation kit 11, and arranges rotating ring auxiliary seal ring 9 between rotating ring 4 and axle and form static seal point; Stationary ring 3 is connected with spring assembly 2 by stationary ring fixation kit 8, and is provided with stationary ring auxiliary seal ring 9 between stationary ring 3 and stationary seat 1 inwall and forms static seal point; Described stationary ring fixation kit 8 is connected by spring assembly 2 with between spring base 7, and by the spring-force driven dual of spring assembly 2, stationary ring 3 and rotating ring 4 close adhesion form dynamic sealing point.
As shown in Figure 2 hair fiber braided ring 91 is set on sealing ring 9 sealing contact surface.
Due to sealing ring body sealing contact surface arranging hair fiber braided ring.Utilize the large surface tension of hair fiber greatly can improve the sealing effectiveness of sealing ring.After mechanical single seal structural wear, the sealing effectiveness of sealing device can also be ensured, substantially prolongs the service life of mechanical single seal device.
