The size fit between the
Sealing ring and the
Sealing groove should follow the following principles:
1. Appropriate clearance: The outer diameter of the sealing ring should be slightly larger than the inner diameter of the sealing groove to ensure that the sealing ring can completely fill the sealing groove and provide a good sealing effect. Usually, the outer diameter of the sealing ring should be approximately 0.2-0.5mm larger than the inner diameter of the sealing groove.
2. Appropriate compression amount: The sealing ring needs to be compressed during installation to produce a sealing effect. The compression amount should be determined based on the characteristics and application requirements of the sealing material. Generally speaking, the compression of the sealing ring should be maintained between 5-30%.
3. Consider thermal expansion and contraction: In high or low temperature environments, sealing materials will experience thermal expansion and contraction. Therefore, when selecting the size of sealing rings and grooves, it is necessary to consider the thermal expansion and contraction coefficient of the material to ensure that good sealing performance can still be maintained even in temperature changes.
4. Consider the elasticity and deformation of the material: The size matching of the sealing ring and sealing groove should take into account the elasticity and deformation characteristics of the sealing material. The sealing ring should be able to recover to the appropriate shape after being compressed to ensure the sealing effect.
These principles can help ensure that the size fit between the sealing ring and the sealing groove is appropriate to achieve a good sealing effect. In practical applications, specific design and selection should also be based on specific engineering requirements and material characteristics.
