The thrust pads will be there at the front or non drive end of the turbine side....These are usually used to limit the axial displacement of the rotor( Means to minimize the movement of rotor axially in order to maintain the axial clearance between the moving blades and the fixed blades of steam turbine rotor).....

What are the types of bearings used in a steam turbine?
main two type of bearing used in steam turbine:(1)thrust bearing (2)general bearing
What is balance piston line of Turbine?
it is used balance axial thrust on turbine rotor due to admitting of high pressure steam in to turbine. it basic purpose is to save thrust bearing.
Why balancing line is providing in steam turbine?
for thrust balancing.
Why extraction taken from steam turbine?
Why extractions are taken out from steam turbine.
What type of cycle used in steam turbine?
Rankine cycle is used in steam turbine
What are the types of bearings used in a steam turbine?
main two type of bearing used in steam turbine:(1)thrust bearing (2)general bearing
What is use of thrust pad in steam turbine?
Thrust pads are used to protect the steam turbine rotor from damage due to axial displacement due to axial thrust created by entry of steam in the turbine. generaly the pads clearence is 0.45mm for a bearing size 250mm.
Where exactaly located thrust bearing in steam turbine?
Thrust bearings are mounted on turbines at or near the end of the shaft, closest to the steam chest (or inlet). This is to maintain the shaft in position with the casing of the turbine, allowing the casing and the shaft to expand evenly together toward the drive end of the turbine.
What is balance piston line of Turbine?
it is used balance axial thrust on turbine rotor due to admitting of high pressure steam in to turbine. it basic purpose is to save thrust bearing.
What is absolute expansion of steam turbine?
it's the thermal expansion in the casing of hp or ip turbine can be noticed by journal or thrust bearing when moving <<
What is positive axial displacement of steam turbine?
axial shift of a steam turbine is the shifting of turbine rotor in the forward and backward direction due to steam thrust on blades of rotor.
Why balancing line is providing in steam turbine?
for thrust balancing.
Why journal bearing used in steam turbine?
to support crankshaft
Can Steam Turbine Thrust Bearing temperature protection device be considered a similar protection for the Steam Turbine Rotor Position protection device?
No these are two different sensors. The thrust bearing temperature trip device measures either the metal temperature of the bearing, or the oil temperature exiting the bearing, or both. If this temperature exceeds recommended temperatures by 10 to 15% the turbine will trip to avoid damaging the bearings or shaft. The rotor position sensor is a proximity cell that monitors the axial position of the turbine rotor, often there is four such sensors mounted at the end of the rotor, if the distance between the sensors and the rotors exceeds a specific distance ( often 15-30 mils) the sensors indicate a failure, if two or three sensors indicate failure the turbine will trip.
What is the clearance gap setting of a steam turbine thrust pad?
0.2 to 0.25 mm

What is catenary in steam turbine?
generally more than three shafts contact by coupling together in steam turbine. the shaft is heavry and will be sag. in order to reduce the bend force on coupling and bend force on bearing, the engienering calclated the shaft and simulated when its in operation condition. so, the catenary curve and bearing elevation data have been provided for steam turbine installation.
