Evaluation criteria for the sealing ability of mechanical seals

　2017-02-07　　

In the actual process, the criterion for evaluating the sealing ability is the deformation strength performance parameters of the material, which is especially sufficient to ensure the minimum contact pressure value of the connecting seal. Under the same conditions, a material with a relatively high sealing ability has a lower sealing contact force. The sealing ability of the material is related to the rigidity of the sealing connection, which is determined by two parameters, namely the deformability of the material and the size and distribution of the gap on the sealing contact surface. For elastoplastic sealing materials, plastic deformation accumulation will occur under cyclic loading.　　251.html,
