Checkpoint of Dry Gas seal lift-off
(OP)
hello, I am looking how the dynamic testing of dry gas/ non-contacting seal which are operated in pumps and compressors, I have seen the images of dynamic test rig of the same but could not understand how the testing is being conducted unlike liquid lubricated seal? what's the checkpoint to ensure that the faces are lifted during testing? is there any device which will signify or point that the test faces are lifted

Is there any prescribed value (in pressure and rpm or pressure difference) where the face should start to lift-off?
What would you recommend to start with the test of these seals?
