*Related Introduction*
The seal ring is the general name of the rotating ring and the static ring (the same below), and it is the most important component of the mechanical seal. The seal ring determines the performance and life of the mechanical seal to a large extent, therefore, some requirements are put forward for it.
Have enough strength and rigidity
It is not damaged under working conditions (such as pressure, temperature and sliding speed, etc.), and the deformation should be as small as possible, and the tightness can still be maintained when the working conditions fluctuate. In particular, the sealing end face must have sufficient strength and a certain degree of corrosion resistance to ensure that the product has a satisfactory service life.
Have good thermal shock resistance
For this reason, the material is required to have a higher thermal conductivity and a smaller linear expansion coefficient, so that it will not crack when subjected to thermal shock.
Small coefficient of friction
The sealing ring matching should have a small friction coefficient.
Good self-lubricating
If a short period of dry friction occurs during work, the sealing end face will not be damaged. Therefore, the seal ring must have good self-lubricating properties, and the seal ring material and the sealing fluid must have good wettability.
Simple structure
The structure of the seal ring should be simple and symmetrical, and the overall structure should be given priority. Combined (such as inlaid) seal ring can also be used, and the sprayed structure of the seal end surface should be avoided as much as possible.
The sealing ring should be easy to process and manufacture
Installation and maintenance should be convenient, and the price should be low.
