ssential elements of a mechanical seal
These are the three essential elements of a mechanical seal:
Seal faces: one rotating with the shaft and one stationary in the pump casing, cover or flange.
Secondary seals: one to seal the rotating face to the shaft and one to seal the stationary face to the pump cover or flange.
Metal parts: to transmit torque and to provide an axial mechanical force to load the faces.
Essential requirements for proper operation of a mechanical oil seals.
These are the essential requirements:
Seal faces must be flat and polished.
Seal faces must be installed perpendicular to the shaft.
Spring force must be sufficient to maintain contact of the faces. mechanical oil seals ssential elements.
