Rubber seals are widely used in machine tools, ships, automobiles, aerospace equipment, metallurgical machinery, chemical machinery, engineering machinery, construction machinery, mining machinery, petroleum machinery, plastic machinery, agricultural machinery and various instruments. Compared with other sealing elements, rubber seals have a wide range of advantages:
1, rubber sealing ring is suitable for rotary motion sealing ring, axial reciprocating sealing ring or combined motion sealing ring (such as rotary reciprocating combined movement).
2, rubber sealing ring is suitable for a variety of sealing forms: static sealing ring, dynamic sealing ring. Rubber sealing ring is suitable for various materials, standardized size and groove, and strong interchangeability.
3, there are many kinds of rubber sealing materials, and the material selection of rubber sealing rings is mainly determined by the working conditions, including the type of media, working temperature, pressure, range, etc. Commonly used material types are: rubber materials: such as nitrile rubber (NBR), fluorine rubber (FKM), silicone rubber (VMQ), ethylene propylene rubber (EPDM), neoprene rubber (CR), polytetrafluoroethylene (PTFE) and so on.
4, the rubber sealing ring design is simple, the rubber sealing ring cross-section structure is extremely simple, with self-sealing function, reliable sealing performance.
5, rubber sealing ring is suitable for a variety of different sealing media: oil, water, gas, chemical media or other mixed media. By choosing the right rubber material and formula design, it can effectively seal oil, water, air, gas and various chemical media. The temperature application range is wide (-60℃~+220℃), and the pressure can reach 1500kg/cm2 when fixed use (and the reinforcement ring is used).
6, rubber sealing ring adopts high pressure vacuum injection molding, small permanent compression deformation, strong extrusion resistance, long service life; The rubber sealing ring has complete specifications and sizes for users to choose. Rubber seals with the same cross section size (or inner diameter size) have a large range of inner diameter size (or section size) to choose from, including non-standard sizes.
7, the rubber sealing ring is easy to install, because the structure of the rubber sealing ring itself and the installation position is extremely simple, it has been standardized, and the installation and replacement are very convenient.
