Abstract
The utility model discloses a dry gas seal friction pair structure. According to the dry gas seal friction pair structure, end faces of moving rings or static rings are respectively provided with a plurality of spiral groove bodies, and the directions of the spiral grooves are matched with the rotating directions of the corresponding moving rings; the groove bodies are two different logarithmic spiral grooves which are gradually narrowed or sharpened from exterior to interior; and the spiral groove bodies of the same type are arranged at intervals, the wide outer edges of the groove bodies are tightly close to one another, and the groove bodies are arc-shaped. By the dry gas seal friction pair structure, a plurality of spiral grooves are formed on the end faces of the moving rings or static rings, so that the operating friction state between the moving rings and the static rings is changed; and moreover, the moving rings and the static rings are in non-contact operation, so that the friction pair structure is energy-saving and environment-friendly, the service life of the friction pair is greatly prolonged, and the maintenance time and material cost are reduced. The dry gas seal friction pair structure provides a reliable sealing guarantee for multiple fluid media, the mechanical seal and equipment are not burnt even under the working conditions without the fluid media, and the safety of the equipment is well guaranteed.
Description
Technical field
The utility model relates to a kind of friction pair structure of non-contact mechanical seal, and it is specifically related to a kind of dry gas seals friction pair structure.
Background technique
At present, as shown in Figure 1, be the rubbing surface structure of existing mechanical sealing rotating ring or stationary ring, it is the pattern of the smooth no cell body of circumference, belongs to contact-type mechanical seal, and its wear resistance and working life are all not satisfactory, so be badly in need of now addressing the above problem.
Summary of the invention
To the problems referred to above, the purpose of the utility model proposes a kind of dry gas seals friction pair structure.
A kind of dry gas seals friction pair structure, it is provided with at least one pair of rotating ring and stationary ring, and said rotating ring or stationary ring one end face are respectively equipped with many spiral cell bodies, and the other end is a plane structure; The direction of said spiral cell body is complementary with corresponding rotating ring rotation direction; Said spiral cell body is two kinds of different log spiral grooves that ecto-entad narrows down gradually or comes to a point, and homotype spiral cell body sets up at interval, and said spiral cell body is circular-arc.
Said rotating ring or stationary ring one end face are respectively equipped with many spiral cell bodies, and the other end is a plane structure; Said rotating ring or stationary ring end face are respectively equipped with many spiral cell bodies, and its spiral fluted direction is complementary with corresponding rotating ring rotation direction; Said spiral cell body is two kinds of different log spiral grooves that ecto-entad narrows down gradually or comes to a point, and homotype spiral cell body sets up at interval, and the wide place of the external edge of said spiral chute relies closely, and said spiral cell body is circular-arc.
The utility model has the following advantages owing to take above technological scheme:
A kind of dry gas seals friction pair of the utility model structure is through offering many spiral chutes to rotating ring or stationary ring end face; Thereby change the Frotteurism that turns round between rotating ring and the stationary ring; Rotating ring and stationary ring are in contactless running; This is energy-conserving and environment-protective not only, in the working life of also having improved friction pair greatly simultaneously, reduce maintenance man-hours and cost of material.And a kind of dry gas seals friction pair of the utility model structure is that multinomial flowing medium provides reliable sealing to guarantee, even under the operating mode of no flowing medium, can not burn mechanical seal and in-house facility, and the Security of equipment is had an individual good guarantee.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is carried out detailed description.
As shown in Figure 2; Be a kind of dry gas seals friction pair of the utility model structural representation, it is provided with at least one pair of rotating ring 1 and stationary ring 2, and said rotating ring 1 can adopt single end face structure or Double End structure to seal with stationary ring 2; When adopting the single end face structure, said rotating ring 1 one sides are provided with stationary ring 2; When adopting the Double End structure, bilateral symmetry is provided with two pairs of rotating rings 1 and stationary ring 2.
Like Fig. 3 and shown in Figure 4; Be the first embodiment's rotating ring of a kind of dry gas seals friction pair of the utility model structure or the end-face structure schematic representation of stationary ring, said rotating ring 1 or stationary ring 2 one end faces are provided with many spiral cell bodies 11, and the other end is a plane structure; The direction of said spiral cell body 11 is complementary with corresponding rotating ring rotation direction; Said cell body 11 is two kinds of different log spiral grooves that ecto-entad narrows down gradually or comes to a point, and identical grooved is set up at interval between the spiral cell body, and it is circular-arc that cell body is.
Like Fig. 5 and shown in Figure 6; Be the second embodiment's rotating ring of a kind of dry gas seals friction pair of the utility model structure or the end-face structure schematic representation of stationary ring; Said rotating ring 1 or stationary ring 2 one end faces are respectively equipped with many spiral cell bodies 12, and the other end is a plane structure, and the direction of said spiral cell body 12 is complementary with corresponding rotating ring rotation direction; Said cell body 12 is two kinds of different log spiral grooves that ecto-entad narrows down gradually or comes to a point; And homotype spiral cell body is set up at interval, and the wide place of spiral chute outer rim relies closely, and it is circular-arc that cell body is.
A kind of dry gas seals friction pair of the utility model structure is through offering many spiral chutes to rotating ring 1 or stationary ring 2 end faces; Thereby change the Frotteurism that turns round between rotating ring and the stationary ring, its principle is: utilize spiral chute to pump into the effect of gas and thunder row step, between rotating ring and stationary ring, produce the gas of certain rigidity; This gas is when separating dynamic and static ring; Also can form one barrier, the about media isolated with friction pair comes fully, thereby has reached the motive sealing effect.Rotating ring and stationary ring are in contactless running, and this is energy-conserving and environment-protective not only, in the working life of also having improved friction pair greatly simultaneously, reduce maintenance man-hours and cost of material.A kind of dry gas seals friction pair of the utility model structure is that multinomial flowing medium provides reliable sealing to guarantee, even under the operating mode of no flowing medium, can not burn mechanical seal and in-house facility, and the Security of equipment is had an individual good guarantee.
The utility model only carries out illustrative with the foregoing description; The structure of each parts, the position is set and connects and all can change to some extent; On the basis of the utility model technological scheme; All improvement and equivalents of individual component being carried out according to the utility model principle all should not got rid of outside the protection domain of the utility model.
