The mechanical seal technology relies on a pair or several pairs of end faces that are relatively sliding perpendicular to the shaft. They can still maintain joint under the action of fluid pressure and other forces of the compensation mechanism, and the auxiliary sealing device can be added to achieve the function of leak prevention. . The mechanical seal makes the contact surface of the static ring and the moving ring fit together forever during the movement. The purpose of sealing is achieved by generating an appropriate specific pressure between the static and moving rings and maintaining a liquid film between them.

The main components used in mechanical seals are end face seal components such as static rings and moving rings; various types of sealing rings and gaskets such as O-type, U-type, and X-type play an auxiliary role; compensation components include springs, push rings, etc. ; Transmission components include transmission screws and transmission pins, etc.; fastening components include many, including push rings, spring seats, glands, and set screws.

Under normal circumstances, mechanical seals are mostly used in equipment such as centrifugal pumps, centrifuges, compressors, and reactors. It has good sealing performance, less leakage, longer service life, lower energy consumption, and does not require frequent maintenance. Mechanical seals are also very good in adaptability. Under normal circumstances, they can adapt to various harsh environments such as automated production, high temperature and high pressure, and harsh requirements for mechanical seals.
