Structural characteristics and performance of circular arc groove mechanical seal

The arc groove non-contact seal belongs to the deep groove thermal fluid dynamic pressure mechanical seal, which fills up for the low speed, high pressure, high temperature and large size occasions that the ordinary shallow groove non-contact seal is not capable of.At the same time, because the arc groove can absorb liquid, the outer edge of the seal ring can be well cooled, and it also has the ability to remove impurities and has nothing to do with steering, therefore, the mechanical seal with the arc groove on the end face has better performance and is very suitable for sealing low viscosity & high parameter media such as high temperature and high pressure water.

Besides，although the circular arc groove mechanical seal can well improve the lubrication between the sealing end faces and is suitable for high-parameter working conditions, its fluid return effect is not good, and there is always leakage from the high pressure side to the low pressure side of the mechanical seal.
