The size match between the sealing ring and the sealing groove should follow the following principles:
1. Temperature and pressure: The size of the sealing ring and sealing groove should take into account the required temperature and pressure conditions. In high temperature and high pressure environments, the sealing ring and the sealing groove should be closely matched to ensure effective sealing performance.
2. Elasticity and deformation: the sealing ring is usually made of elastic material, and its size should take into account the elastic and deformation characteristics of the material. The sealing ring should be able to adapt to the shape change of the sealing groove and be able to produce a suitable deformation under pressure to achieve sealing.
3. Wear and wear compensation: The size of the sealing ring and the sealing groove should take into account wear and wear compensation. After long-term use, the sealing ring and sealing groove may be worn, so a certain wear compensation space should be reserved to ensure the durability of the sealing performance.
4. Installation and disassembly: the size of the sealing ring and the sealing groove should take into account the ease of installation and disassembly. The sealing ring should be able to be easily installed into the sealing slot and can be easily removed when required.
5. Material selection: The size of the sealing ring and the sealing groove should take into account the expansion coefficient and contraction coefficient of the material. The coefficient of expansion and contraction of different materials is different, so when the temperature changes, the size of the sealing ring and the sealing groove should be able to maintain a suitable sealing performance.
The size match between the sealing ring and the sealing groove should take into account factors such as temperature, pressure, elasticity, deformation, wear, installation and disassembly to ensure effective sealing performance and reliable use. The specific size fit should be selected and designed according to the specific application requirements and material characteristics.
