Principles Overview

Mechanical seals are a number relative to the perpendicular to the axis or sliding the end in the fluid pressure and compensation mechanism of elastic (or magnetic) is posted under merged with a secondary sealing and choke leaking shaft seal.
Mechanical seal structure used by the stationary ring (static) 1, turn the ring (rings) 2, elastic element 3 set screws, springs, 4, 5, rotating ring supporting ring 6, and still an Assistant sealing ring 8 elements, anti-rotating pin 7 fixed to the cover 9 to prevent static from rotating.
Rotating ring and stationary ring according to whether they have axial compensation and called the compensation ring or non-compensating ring.
