Gas Sealing Performance Study of Metal W Shaped Seal Ring

Abstract

Gas sealing performance of metal seal ring directly affects the security and reliability of equipment operation. Gas static seals of W-ring is taken as a study object, based on the theory of rough surface contact model and the theory of gas average flow model in the rough surface gap, the gas sealing leakage model is established to analyze the relationship between the leakage and the sealing load and surface roughness parameters.
