Description

Technical Field

[0001] The present invention belongs to the field of manufacturing seals for high-pressure machinery, and particularly relates to a separated linkage cooling type seal end cover. Background Art

[0002] Currently, in a mechanical structure that requires sealed transmission, a seal ring sleeve is often used to make a sealed connection with a rotating shaft. The rotating shaft rotates and abuts against the seal ring sleeve. It is necessary to ensure the stability of the sealing performance. Especially in the field of high-pressure mechanical seals, the sealing performance requirements of the seals required by high-pressure machinery are higher. When a chemical reaction occurs inside a general reaction kettle, high-temperature and high-pressure gases may sometimes be generated inside the kettle body. Thus, it is necessary to ensure the high-pressure sealing performance of the seal ring sleeve. The seal ring sleeve is generally made of a rubber material. When the seal ring sleeve is continuously impacted by high-temperature and high-pressure gases for a long time, the seal ring sleeve will soften, thus greatly reducing the sealing performance of the seal ring sleeve. Therefore, if the seal ring sleeve can be cooled, the service life and sealing stability of the entire structure will be greatly improved. However, when the reaction occurs inside the kettle body, the temperature is not high, and at this time, heat dissipation is not required. Therefore, there is no need for additional heat dissipation operations. So, it is necessary to improve the flexibility of the structure, thereby improving the sealing stability of the structure, extending the service cycle, reducing the load, and achieving the purpose of energy conservation.
