DESCRIPTION

 

The sealing bearing is a significant composition in hydrogen-cooled generator, preventing hydrogen leakage from the ends of both sides of the rotor.

 

Working principle: single flow disc seal pad has two oil cavities: the seal oil chamber and the thrust chamber. The thrust chamber is similar to the springs in mechanical seal.the oil pressure effect is on the different diameter of section which makes the seal pads always stick to the rotor’s seal plate. The seal oil pass the middle SMM’s oil hole, entering the interval between the babbit piles and the seal plates. Because the babbit pile which processes along the rotating direction of the rotor has oil wedge, thus form the oil film. Not only has the lubrication action, but also prevent the hydrogen inside leaking. The seal oil pressure always higher than the hydrogen pressure: 0.16Mpa. The sealing bearing’s every oil chamber adapts the V rubber ring to seal. Between the sealing bearings and the seal cartridge, it is allowed to relatively sliding. When the rotor expands, it drives the seal pile shift along the axial direction.

 

Installation: compared with the other sorts of sealing pile, the disc sealing tile’s installation is simple, for example, the generator’s rotor and the seal pad total backlash of the radial direction to 6.smm.thus it is no need to consider the problem of dynamic and static.
