Background Knowledge：
An important indicator of O-ring design——working compression rate
If working compression rate is too large,although sealing is reliable, friction and deformation will increase, and excessive wear and permanent deformation are prone to occur. Especially as auxiliary sealing element of compensation ring, O ring’s working compression rate must be suitable. If it is too large, which will cause the compensation ring to be unable to float, specific pressure of end faces of the mechanical seal will decrease, thus the mechanical seal will fail. However, if too small, the O-ring seal will be unreliable. Therefore,working compression rate is generally selected from 12% to 18%.
