Abstract

The invention discloses a novel single end surface mechanical seal. The novel single end surface mechanical seal includes a seal surface formed by a rotating ring arranged on a shaft and a stationary ring arranged in a stationary ring seat, wherein the rotating ring is fixed on the shaft through a rotating ring fixing assembly, and a rotating ring auxiliary seal ring is arranged between the rotating ring and the shaft to form a stationary seal point; the stationary ring is connected with a spring assembly through a stationary ring fixing assembly, and a stationary ring auxiliary seal ring is arranged between the stationary ring and the inner wall of the stationary ring seat to form a stationary seal point. The novel single end surface mechanical seal is characterized in that ring-shaped grooves are formed on seal contact surfaces of the seal rings and are filled with hair fiber woven rings. The novel single end surface mechanical seal has the advantages that the hair fiber woven rings are arranged on the seal contact surfaces of seal ring bodies on the basis of ordinary seal rings, so that the large surface tension and high corrosion resistance of hair fibers can greatly prolong the service lives of the seal rings and improve the sealing effect of the seal rings; the sealing effect of the sealing device can still be guaranteed even after the single end surface mechanical seal structure is worn, so that the service life of the single end surface mechanical seal device is greatly prolonged.

Description

A kind of novel single-end face mechanical seal
Technical field
The present invention relates to a kind of single mechanical end face seal.
Background technique
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 working life shortening mechanical seal.
Summary of the invention
The object of the invention 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 present invention for achieving the above object, adopts following technological 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 fixing-assembly, 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 fixing-assembly, 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 seal 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 seal ring is O shape rubber seal.
The present invention, on the basis of conventional seals circle, seal ring sealing contact surface arranges hair fiber braided ring.Utilize large surface tension and the corrosion resistance of hair fiber, considerably increase working life and the sealing effect of seal ring.After mechanical single seal structural wear, the sealing effect of seal arrangement can also be ensured, substantially prolongs the working life of mechanical single seal device.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is ring structure schematic diagram.
Embodiment
Single mechanical end face seal as shown in Figure 1, rotating ring 4 is fixed on axle by rotating ring fixing-assembly 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 fixing-assembly 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 fixing-assembly 8 is connected by spring assembly 2 with between spring seat 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 seal ring 9 sealing contact surface.
Due to seal ring body sealing contact surface arranging hair fiber braided ring.Utilize the large surface tension of hair fiber greatly can improve the sealing effect of seal ring.After mechanical single seal structural wear, the sealing effect of seal arrangement can also be ensured, substantially prolongs the working life of mechanical single seal device.
