Principle of double end face mechanical seal

Principle and single face mechanical seal is basically the same as the double mechanical seal, are on the face perpendicular to the axis of rotation (friction) device to keep the relative sliding postmerger in fluid pressure and the elastic compensation mechanism and the role of coordination of auxiliary seals which prevent fluid leakage. Double end mechanical seal structure such as work, by the fluid pressure (medium pressure) force and the elastic force of the elastic elements caused by, in the end face sealing ring on an appropriate pressure (pressure), the two contact faces (dynamic ring and the static ring end) are tightly combined. Maintain a very thin layer of liquid film and the minimum in the gap between end faces, so as to achieve the purpose of sealing.
