Silicone O-rings are an important part of many mechanical equipment. For silicone O-rings, many sealing levels have a great impact on the application of silicone O-rings. So about the sealing principle of silicone O-rings, What other ones are there?
Regarding the sealing principle of silicone O-ring, the main manifestations are:
The initial radial or axial compression during installation gives the silicone O-ring its own initial sealing ability. The sealing force generated by the system pressure and the initial sealing force combine to form a total sealing force, which increases as the system pressure increases. Silicone O-rings play an outstanding role in static sealing situations. However, in suitable dynamic situations, silicone O-rings are often used, but they are limited by the speed and pressure at the seal.
As can be seen from the above, for silicone O-rings, their sealing performance is not only related to their own quality, but also has a lot to do with the space of the mechanical equipment where the silicone O-rings are installed.
As the scientific and technological level of today's market continues to improve, there are higher quality requirements for the production of silicone O-rings. For the production of silicone O-rings, there are several key points:
1. Elastic and resilient.
2. Appropriate mechanical strength, including expansion strength, elongation and tear resistance, etc.
3. Stable performance, not easy to swell in the medium, and small thermal shrinkage effect (Joule effect).
4. Easy to process and shape, and can maintain accurate dimensions.
5. Does not corrode the contact surface, does not pollute the medium, etc.
