What is Turbine Supervisory Instrumentation (TSI

The thrust bearing is a fix point of the shaft itself relative to the casing. The thrust bearing can move axially within its clearances. The supervision of the axial shaft position allows to protect the turbine against shaft displacements caused by excessive thrust rates during transient conditions and disturbances.

Pump Thrust

Jul 10, 2001Well, the axial thrust is the change in momentum of the fluid along the x-axis (with that axis defined as the axis of rotation of the shaft) plus the pressure differential between the back of the impeller and the front of it - corrected for the area of thrust - that being the cross section of the impeller minus any balance holes.
