The following factors need to be considered when selecting the wire diameter of the sealing ring:
1. Application scenarios of sealing rings: Different application scenarios have different requirements for the wire diameter of sealing rings. For example, the automotive engine seal ring needs to withstand high temperature and high pressure, so it is necessary to choose a thicker wire diameter; The sealing ring of some small household appliances can choose a thinner wire diameter.
2. The material of the sealing ring: The material of the sealing ring will also affect the choice of wire diameter. Sealing rings of different materials have different elasticity and wear resistance, so it is necessary to choose the appropriate wire diameter according to the characteristics of the material.
3. Size of the seal ring: the wire diameter of the seal ring should match the size of the seal ring. If the wire diameter is too large, the sealing ring may not be fully embedded in the sealing groove; If the wire diameter is too small, the sealing ring may not be effectively sealed.
4. Compression of the seal ring: The seal ring needs to be compressed during installation to ensure effective sealing. Therefore, it is necessary to choose the appropriate wire diameter according to the compression of the sealing ring. Generally speaking, the larger the wire diameter, the greater the compression of the sealing ring.
The selection of the wire diameter of the sealing ring needs to consider the application scenario, material, size and compression amount.
