What are the technical requirements for container mechanical seals?

Sealing ring is the general term for dynamic and static rings (the same), and is an important component in machine sealing. The sealing ring depends to some extent on the performance indicators and service life of the machine seal, so there are some regulations.

Having sufficient strength and rigidity

Under the nature of work (such as pressure, temperature, rolling rate, etc.), it should not be damaged, and deformation should be minimized as much as possible. It should be able to maintain sealing even when the nature of work fluctuates. Especially the sealing end face requires a certain level of strength and corrosion resistance to ensure the satisfactory service life of the product.

Good heat shock resistance level

Therefore, it is stipulated that the material has a high heat transfer coefficient and a small thermal expansion coefficient, and will not crack when subjected to thermal shock.

Low frictional resistance

The sealing ring should have a small frictional resistance when paired.

Better self-lubricating properties

If there is short-term dry friction during work, it will not damage the sealing end face. Therefore, the sealing ring should have good self-lubricating properties, and the sealing ring material and sealing liquid should also have good permeability.

Compact structure

The structure of the sealing ring should be simple and symmetrical, with priority given to the overall structure or combination (such as inlay) of the sealing ring, and the coating structure of the sealing end face should be minimized as much as possible.

Sealing rings are easy to produce and manufacture

Assembly and maintenance should be convenient, and the price should be cheap.
