How to improve the sealing material and performance of mechanical rubber sealing ring

Improving the sealing materials and performance of mechanical rubber seals can be started from the following aspects:

Material selection: Choosing the right rubber seal material is the key to improve the sealing performance. Common sealing materials include styrene butadiene rubber (NBR), fluorine rubber (FKM), nitrile butadiene rubber (HNBR) and so on. Different materials have different temperature resistance, chemical resistance and wear resistance, according to the characteristics of the use of the environment and the medium to choose the most suitable material.

Seal ring design: Optimizing the design structure of the seal ring can improve its sealing performance. For example, increasing the pressure area of the sealing ring or using a multi-channel sealing structure can enhance the sealing effect. At the same time, the reasonable selection of the section shape, hardness and thickness of the sealing ring also has an impact on the sealing performance.

Surface treatment: The surface treatment can increase the adhesion and friction between the sealing ring and the contact surface, and improve the sealing performance. Common surface treatment methods include coating the surface with special lubricants, increasing the surface roughness, or using special coating technologies.

Sealing ring installation: The correct installation method and technology also have an important impact on sealing performance. Ensure that the seal is properly compressed and positioned during installation to avoid over - or under-compression. At the same time, following the correct installation sequence and steps is also the key to ensure sealing performance.

Regular maintenance and replacement: Regular inspection and maintenance of mechanical seals, including timely replacement of aging, damaged or failed seals, can ensure its good sealing performance. Regular lubrication and cleaning of the seal ring, and pay attention to eliminate the accumulation of dirt and impurities, can extend the service life of the seal ring and improve the sealing performance.

In short, improving the sealing materials and performance of mechanical rubber seals requires comprehensive consideration of material selection, design optimization, surface treatment, installation technology and regular maintenance. Reasonable selection of materials, optimal design, correct installation and regular maintenance of the seal ring will effectively improve the sealing performance of the mechanical rubber seal ring.
