Abstract
The invention discloses a mechanical seal for slurry medium. On a shaft are sequentially mounted a transmission ring, a rotation ring, a compensation ring and an end cover; one end of the end cover located at the compensation ring is fitted at the outer side of the compensation ring; and a spring is mounted in the space enclosed by the compensation ring, the end cover and the shaft and has one end fitted at the end part of the compensation ring. The invention is characterized in that the transmission ring and the rotation ring adopt milling transmission on the circumference to realize reliable transmission with respect to the slurry medium working condition, the spring built-in structure is adopted, and slurry is isolated from the compensation mechanism by an anti-blocking seal ring. According to the invention, the problem of easy slurry blocking is effectively solved, and the seal end face adopts a wear-resistant material to reduce the influence of particles on the mechanical seal.
Description
Technical field
The present invention relates to the mechanical sealing technology field, be specifically related to a kind of mechanical seal that is used for slurry medium.
Background technique
Slurry medium in the chemical industry has that easy crystallization, severe corrosive, fiber and impurity are many, thickness, be prone to characteristics such as stifled, and conventional many spring structures mechanical seal can not be used for this medium, can't guarantee normal seal operation.
Summary of the invention
The objective of the invention is to overcome above-mentioned not enough problem, a kind of mechanical seal that is used for slurry medium is provided.
The present invention for realizing the technological scheme that above-mentioned purpose adopted is: a kind of mechanical seal that is used for slurry medium; Transmission ring, rotating ring, compensated loop, end cap are installed on axle successively; The end that said end cap is positioned at compensated loop is sleeved on the outside of compensated loop; In the space that the three surrounded spring is installed at said compensated loop, end cap, axle, an end of said spring is sleeved on the end of said compensated loop.
On the circumference at said transmission ring and the vertical surface of contact place of rotating ring, mill flat.
General stopper ring is installed between said end cap and the compensated loop.
Characteristics of the present invention are: be primarily aimed at the operating mode in slurry medium; Transmission ring and rotating ring have adopted and on circumference, have milled flat transmission, make transmission more reliable, and adopt the spring embedding structure; And through a general stopper ring isolation slurry and a compensation mechanism with anti-ponding; Effectively solved the susceptible to plugging problem of slurry, seal face has adopted high-abrasive material, has reduced the influence of particle to mechanical seal.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is that the circumference of primary sealing area mills flat schematic representation.
Wherein: 1, transmission ring 2, rotating ring 3, compensated loop 4, general stopper ring 5, spring 6, end cap.
Embodiment
Like Fig. 1, shown in 2; Structure of the present invention is that transmission ring 1, rotating ring 2, compensated loop 3, end cap 6 are installed on axle successively; The end that said end cap 6 is positioned at compensated loop 3 is sleeved on the outside of compensated loop 3; In the space that the three surrounded spring 5 is installed at said compensated loop 3, end cap 6, axle, an end of said spring 5 is sleeved on the end of said compensated loop 3; Because the mechanical seal dielectric viscosity that slurry medium is used is big, requires reliable transmission, so be different from the common transmission screw kind of drive; But adopted on the circumference at transmission ring 1 and the vertical surface of contact place of rotating ring 2, mill flat, through milling flat transmission, again because slurry medium and be prone to stop up the compensated loop 3 of mechanical seal; Influence compensatory and the following property of mechanical seal; So adopt the built-in spring structure, and the general stopper ring 4 with anti-ponding be installed between end cap 6 and compensated loop 3 isolated slurry and compensation mechanism, with the susceptible to plugging problem of effective solution slurry; For reducing the influence of particle to mechanical seal; Seal face adopts high-abrasive material, and compensated loop 3 allows bigger string quantity of motion, allows bigger alignment error.
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.
