*Related Introduction*

Mechanical seal, as an important mechanical basic part in the production of mechanical equipment, plays a key role in many equipment and production and use, and often becomes a technical bottleneck restricting the research and development of the entire equipment. Therefore, the mechanical seal is The use of it is quite cautious. In our country, with the public's understanding and deepening of the importance of basic components, the existing tendency and concept of "heavy main engine and light basic components" began to reverse, and gradually began to pay attention to the use of basic components, governments at all levels and the industry Attention and investment in mechanical seal technology are also gradually increasing.
