What is the purpose of a kingsbury thrust?
It counter acts forces acting parrell to the compressors shaft (prevents axle displacement)
What is the purpose of the gland seal system?
To prevent steam from leaking out of turbine or from air leaking in.
What would cause the atmospheric valve to open (ATM valve)
High steam condensor pressures. Steam surface condersons operate on a vacuum (ATM closed in vacuum), if you come out it blows the ATM.
How is the water level on the hot well regulated?
Combined operation of a recirculation valve and and an overboard valve
What device records speed of turbine shaft?
Tachometer
What controls the of steam entering the steam turbine chamber and is a It is a automaticcontrol which takes over at a pre-determined RPM speed
Governors
What valve is located at or near the gimble valve. This valve is used during warm up period of the steam turnine
Steam By-Pass Valve
Iindividually drilled and reamed standard nozzle rings are used sometimes and are independent of the turbine case which makes the easier to replace
Stationary Steam Path Components
What is critical speed on a steam turbine?
The speed you must get pass as quick as possible.
Once you get to the speed you want to get it even higher to ensure you dont damage turbines
What is the purpose of the auxilary oil pumps
To insure adaqute lubrication during start up and shut down.
