Research on Sealing Performance and Opening Characteristics of Lip-shaped Seal Ring for the Stirred Tank
In this paper,through establishing a numerical analysis model for the lip-shaped seal,both static sealing performance and dynamic opening characteristics of the open lip seal were investigated and then verified through tests.The results show that,the medium pressure has obvious influence on the reverse opening pressure,and the reverse opening pressure increases 0.01 MPa for every 0.01 MPa increased in the medium pressure;and the influence of structural parameters is not obvious,and changing structural param-eters of the lip can improve sealing performance in static contact.In addition,simulating actual working condition of the seal through tests and accurately measuring reverse opening pressure of the lip show that,the average error between test value and calculated value is about 10%.
