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.
In Turbine position of bearing and is alignment are different, with reference to catenary curve & load on the bearing position of different bearings are decided.
good
Catenary is the curve formed by the Turbine Rotors when they are placed on their respective Bearings.The level of each bearing and its housings are ear marked or indicated by the manufacturer of turbines.At the time of erection this is to be followed by laser alignment or by piano wire,water level etc
Why extractions are taken out from steam turbine.
becouse this steam is use repetdly for the turbine
The preventive maintenance of steam turbine mainly entails frequent servicing of the parts. This will ensure a smooth performance of the steam turbine.
manish
Rankine cycle is used in steam turbine
Steam or water, it works the reverse of a fan, where the fan pushes air down, the turbine is turned by the steam or water. there's a shaft leading from the turbine to the generator, which produces the electricity
why we are maintain vacuum in steam turbine at steam outlet or exhaust side
Steam turbine nozzle clearance is the total energy content available in steam. This is through a valve.
inconsistent load will cause steam turbine hunting.
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.
Depends on the turbine
