What are the main aspects of the development capability of mechanical seals? What should be the development trend of mechanical seals? Let's follow the editor below to learn more.
For shaft rotation dynamic sealing systems, most of the market still uses ordinary standard oil seals. When there are pressure design requirements for shaft rotation sealing equipment, domestic pressure resistant oil seal components provide a pressure level of 1 to 3 megapascals, while imported seals can provide a pressure level of 10 megapascals, at least three times higher than domestic products. For dynamic hydraulic pressure resistant oil seal components, they have not yet been widely used in mechanical shaft rotation sealing systems.
2. For the design of static sealing systems, plant fiber and asbestos material sealing products have gradually been eliminated. However, chemical polymer material sealing products have not been widely used in some liquid static sealing devices. Currently, there are relatively few domestic sealing brands that can be used in hydraulic mechanical sealing system equipment, and the manufacturing level and quality stability of domestic sealing products are far behind that of imported sealing products.

3. For the reciprocating motion sealing system of hydraulic cylinder bodies, the vast majority of domestic engineering hydraulic machinery on the market currently use U-shaped sealing rings for the main seal design of dynamic sealing systems for hydraulic cylinder bodies. After the 1990s, the design of reciprocating dynamic sealing systems for hydraulic cylinder bodies in engineering hydraulic machinery began to use more complex composite designs of U-shaped rings and coaxial sealing components. There are currently mature designs internationally, including 5-piece combination rings, 4-piece combination rings, 3-piece combination rings, and 2-piece combination rings, which are applied to the piston belt support ring of hydraulic cylinder bodies. The production process of combination rings as sealing components is relatively complex, and the domestic design and manufacturing capabilities are not yet capable of mass production. The quality level of combination rings is still relatively poor.
After reading the above content, I believe everyone already knows about the development and performance of mechanical seals.
