How to choose a silicone O-ring?
The application of silicone O-rings is a very important part of industrial production, especially with the continuous strengthening of industrial development, the importance of various industrial production is becoming more and more common.
Most of the applications of silicone O-rings are static seals and dynamic seals. It is precisely because of such application fields that the proportion of silicone O-rings used in many seals has greatly increased. There will be some differences in dynamic seals. So in this case, how should we choose the silicone o-ring?
For static sealing, the compression rate of the silicone o-ring is set at about 25**. (Oring section diameter-groove depth)/Oring section diameter≈25**; dynamic seal is divided into circular rotation and axial reciprocating motion. Under the premise of rotating in the circumferential direction, not all silicone o-rings can achieve a complete sealing effect, so once this happens, it is not recommended to use silicone o-rings. If the axis moves back and forth, the compression rate should be adjusted appropriately to avoid the silicone o-ring from being damaged too quickly. At the same time, the thickness of the moving surface is required to be higher.
Only with a sufficient understanding of the silicone o-ring, can the silicone o-ring be used to give full play to its functional effect and avoid problems due to improper selection.
