The stability of the mechanical seal material to the sealing medium
In mechanical sealing devices, the working capacity of the sealing material is first determined by the stability of the material in the sealing medium. The stability of the mechanical sealing material in the sealing medium is a comprehensive criterion including multiple characteristics. First of all, it must be based on the premise that no chemical reaction occurs between the sealing material and the sealing medium. Secondly, the sealing material must have stability against contact force relaxation and creep.
The creep of the sealing material will cause the seal to be squeezed out of the sealing gap, and the relaxation of the sealing stress will be accompanied by the increase of leakage. The evaluation of the working capacity of the corrosive medium sealing material can be used as a criterion for the stability of the sealing material against the medium to a certain extent. 260.html,
