The importance of mechanical seals in the production and use of industrial equipment

Mechanical sealing technology, that is, the sealing technology with no relative movement between the joint surfaces. As far as a medium-scale petrochemical plant is concerned, there are tens of thousands of static sealing points, and there are many types of sealed media. Most of the dangerous media that burns easily with coal and are corrosive or toxic. Once the seal fails, it will not only cause waste, but also pollute the environment, and even cause personal injury and property damage. Therefore, the study of its mechanism and components is of great significance. Static seals have been used by human society for a long time, such as the seals of food sour barrels. However, it was not until the industrial revolution (the end of the 18th century) that the use of steam required steam engines and boiler pressure vessels to achieve rapid development. The development of the chemical industry and petrochemical industry further accelerated the technological progress of static sealing. The current static sealing technology can solve most of the static sealing problems, the pressure is from vacuum to 3001^1^, the temperature is between -180~12001, and the diameter is up to 2 claws. However, due to the complex effects of static sealing technology, it is difficult to study the flash element, and the experimental cost is high. Therefore, the important performance indicators of static sealing are still uncertain, although the reliability still cannot meet the engineering requirements.　　185.html,
