Analyze the performance time of rotating dynamic and static seal rings

Frequently used dynamic ring or static ring on the rotary joint or rotary joint dynamic seal ring;
Sealing rings should have good thermal shock resistance: materials with higher thermal conductivity and smaller coefficient of linear expansion are required, and will not crack when subjected to thermal shock.
Has sufficient strength and rigidity: mechanical seals are not damaged under working conditions, deformation should be as small as possible, and sealability can still be maintained when operating conditions fluctuate.
There should be a small coefficient of friction and good self-lubrication: matching of the seal ring should have a small coefficient of friction and good self-lubrication, and the seal ring material and seal fluid should also have good wettability.
If dry friction occurs for a short period of time during operation, the sealing face is not damaged.
The sealing face should have sufficient hardness and corrosion resistance: to ensure satisfactory service life of the double-faced mechanical seal under working conditions.
Strive for simple symmetry and give priority to the use of integral structure: You can also use a combination of seals, try to avoid the use of sealed end spray structure.
Sealing rings are easy to process and manufacture: installation and maintenance are convenient and inexpensive.
