Material selection: Selecting the right rubber seal ring material is the key to improving sealing performance. Common sealing materials include styrene-butadiene rubber (NBR), fluororubber (FKM), nitrile rubber (HNBR), etc. Different materials have different temperature resistance, chemical resistance and wear resistance. The most suitable material should be selected according to the characteristics of the use environment and the medium.
Sealing ring design: Optimizing the design structure of the sealing ring can improve its sealing performance. For example, increasing the pressure area of ​​the sealing ring or adopting a multi-channel sealing structure can enhance the sealing effect. At the same time, the reasonable selection of the cross-sectional shape, hardness and thickness of the sealing ring also affects the sealing performance.
Surface treatment: 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 applying special lubricants on the surface, increasing the surface roughness or using special coating technology.
Sealing ring installation: The correct installation method and technology also have an important impact on the sealing performance. Ensure that the sealing ring is correctly compressed and positioned during installation to avoid excessive or insufficient compression. At the same time, following the correct installation sequence and steps is also the key to ensuring sealing performance.
Regular maintenance and replacement: Regular inspection and maintenance of mechanical seals, including timely replacement of aged, damaged or failed seals, can ensure good sealing performance. Regular lubrication and cleaning of the seals, and attention to the removal of accumulated dirt and impurities, can extend the service life of the seals and improve the sealing performance. In short, improving the sealing materials and performance of mechanical rubber seals requires comprehensive consideration from aspects such as material selection, design optimization, surface treatment, installation process, and regular maintenance. Reasonable material selection, optimized design, correct installation and regular maintenance will effectively improve the sealing performance of mechanical rubber seals.
