The general name of the moving ring and the static ring is called the sealing ring, which is the main component of the mechanical seal. The seal ring largely determines the performance and life of the seal, so the seal has some specific requirements for the seal ring.

1. The sealing ring should be easy to process and manufacture

Second, the installation and maintenance should be convenient and the price should be low.

3. The sealing ring must have good thermal shock resistance, so the material must have a high thermal conductivity and a small linear expansion coefficient, so that it will not crack when subjected to thermal shock.

4. The sealing ring must have good self-lubricating properties to prevent short-term dry friction during work and not damage the sealing end face. Therefore, the sealing ring material and the sealing fluid must have good wettability.

5. Simple structure

The structure of the sealing ring is simple and symmetrical. The integral structure is given priority, and the combined sealing ring can also be used. Try to avoid using the sprayed structure on the sealing end face.

6. Sufficient strength and rigidity

The mechanical seal is not damaged under working conditions, and the deformation should be as small as possible, so that the sealing performance can still be maintained when the working conditions fluctuate. In particular, the sealing end face must have sufficient strength and certain corrosion resistance to ensure the service life of the product.
