Abstract
The invention discloses a dry gas sealing structure which comprises a shaft sleeve, a static ring and a rotating ring, wherein the shaft sleeve is sleeved on the shaft, the rotating ring is installed in the shaft sleeve, the static ring is installed on the rotating ring, and a spring is installed between the static ring and a spring seat. The dry gas sealing structure provided by the invention has the following characteristics: the structure is simple and reliable, the sealing effect is good, and the sealing structure does not need to be maintained when in use, thus economic losses can be reduced.
Description
Technical field
The present invention relates to the field of sealing technology of pump, be specifically related to be used for a kind of dry gas sealing structure that heating agent jumps.
Background technique
The sealing of pump is the key that influences quality, and original heating agent pump seal structure is poor, and oil leakage phenomenon is serious, and maintenance cost is high.
Summary of the invention
The objective of the invention is to overcome above-mentioned not enough problem, a kind of dry gas sealing structure is provided.
The present invention for realizing the technological scheme that above-mentioned purpose adopted is: a kind of dry gas sealing structure; Comprise axle sleeve, stationary ring, rotating ring; Said axle sleeve is sleeved on the axle; Said rotating ring is installed in the said axle sleeve, on the said rotating ring stationary ring is installed, between said stationary ring and the spring seat spring is installed.
Between said axle sleeve and the rotating ring seal ring is installed.
Characteristics of the present invention are: simple in structure, reliable, good sealing effect does not need in the use to safeguard, reduces economic loss.
Description of drawings
Fig. 1 is a schematic representation of the present invention.
Wherein: 1, axle sleeve 2, seal ring 3, rotating ring 4, stationary ring 5, spring 6, spring seat.
Embodiment
As shown in Figure 1, the present invention includes axle sleeve 1, stationary ring 4, rotating ring 3, said axle sleeve 1 is sleeved on the axle; Said rotating ring 3 is installed in the said axle sleeve 1, between said axle sleeve 1 and the rotating ring 3 seal ring 2 is installed, on the said rotating ring 3 stationary ring 4 is installed; Between said stationary ring 4 and the spring seat 6 spring 5 is installed, rotating ring 3 sealing surfaces process is ground, polishing treatment, and processes the fluid dynamic pressure groove of special role in the above; During 3 rotations of dry gas seals rotating ring, sealing gas is inhaled in the dynamic pressure groove, and is radially moving towards the sealing weir flow respectively towards the center by external diameter; Because the throttling action on sealing weir; The gas that gets into sealing surface is compressed, and gas pressure raises, and is open in this pressure effect lower sealing surface; The gas that flows forms the very thin air film of one deck between two sealing surfaces, it has substituted the liquid film between two sealings of conventional seals.
The above; Be merely the preferable embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any technician who is familiar with the present technique field is equal to replacement or change according to technological scheme of the present invention and inventive concept thereof in the technical scope that the present invention discloses, all should be encompassed within protection scope of the present invention.
