Embodiment Construction
[0007] A mechanical sealing device suitable for industrial circulating water with high turbidity described in the present invention comprises a static ring, a compensating assembly, a moving ring, a retaining ring, a set screw and a sealing ring. The compensation assembly is composed of a transmission seat 1, a transmission ring 3, a spring 9, an integrated screw 4, a transmission pin 2 and a transmission ring 3 as a whole. A transmission pin 2 is specially provided, supplemented by an integrated screw 4 to ensure the transmission reliability of the transmission seat 1 and the transmission ring 3 . The compensation assembly transmits the torque through the set screw 12 and the key 13, and keeps synchronous with the rotating shaft. Fork transmission is adopted between the moving ring 6 and the transmission ring 3 of the compensation assembly, and the moving ring 6 and the rotating shaft use the moving ring sealing ring 10 to prevent the leakage of the medium. A retaining ring ...

The invention relates to a mechanical sealing device applicable to high-turbidity industrial circulating water. According to the technical scheme, the mechanical sealing device applicable to high-turbidity industrial circulating water is characterized in that modular design is adopted, and the mechanical sealing device is more convenient and faster to install; the end face of the mechanical sealing device is provided with a fluid dynamic pressure ring groove to enhance the lubricity of the end face; moving and static rings are both provided with brittle fracture resistance silicon carbide friction pairs containing reinforcing materials. Through an integral structure, minimum deformation under a high-pressure environment is guaranteed. Multiple springs are designed for providing the uniformcompensative force and guaranteeing the parallelism degree during operation; the moving ring and a transmission ring adopt the form of a shifting fork, and the operation reliability under the high-pressure environment is improved; by means of a compound transmission mode, the transmission reliability of the mechanical structure under the high-pressure environment is guaranteed.
Description
technical field [0001] The invention relates to a mechanical sealing device suitable for high turbidity industrial circulating water. Background technique [0002] At present, with the rapid development of my country's economy and the continuous advancement of industrialization, the demand for electricity consumption in all walks of life is also increasing day by day; about 75% of the electricity in the entire power generation industry in my country comes from coal, however, the sulfur content in coal is as high as 1%. ~2%, resulting in the emission of sulfur dioxide from coal combustion has accounted for 93.9% of the total emission, and the annual emission of sulfur dioxide in the country has reached more than 20 million tons, ranking first in the world. Coal conversion is increasingly becoming a research focus. Coal chemical industry is an industry that uses coal as raw material, converts coal into gas, liquid and solid products or semi-products through certain chemical me...
