Why is the liquid film reaction force between the rotating ring and the stationary ring zero at the shaft?
Thread Content
It is easy to understand why the liquid film reaction force between the rotating ring and the stationary ring is the pressure of the sealing chamber at the medium side, but why is it 0 at the shaft side?
I’m not quite sure what the original poster is trying to say. Do you mean the atmospheric end by \"shaft end\"? If it is the atmospheric end, isn’t that exactly 0?

The pressure at the atmospheric side is 0, while the pressure at the medium side is the pressure in the sealed chamber; there is a pressure difference. I still don’t understand why the medium needs to be sealed When the moving ring rotates, will other forces prevent the medium from passing through the contact surface between the moving and stationary friction pairs?
Break it down into several parts; don’t focus on just one aspect, as that can lead to getting stuck in a dead end. It’s much better to think about it by looking at the actual object:handshake
