The mechanical seal guarantees the stability of the seal under pressure and other external factors

　2017-02-14　　

The liquid structure characteristics cannot guarantee the stability of the seal under the action of the mechanical seal pressure and other external factors. In order to resist the pressure of the sealing medium, the mechanical sealing material should also have a solid nature, that is, have sufficient rigidity to ensure that the shape is unchanged and the ability to resist deformation. Therefore, the currently envisioned sealing material should have both liquid and solid properties.

Due to the influence of external factors such as friction, temperature change, corrosion, etc., the use conditions of the sealing material in contact with the seal are far from ideal. In this case, it is of decisive significance that, under the action of many unfavorable factors, the criteria for obtaining the long-term working ability of the sealing material. Especially with the development of modern technology, various sealing conditions continue to emerge, and many requirements for temperature resistance, pressure resistance, corrosion resistance, abrasion resistance, impermeability, and radiation resistance are put forward for sealing materials.　　266.html,
