it controls the over pressure of the water
The turning gear main motor and piggy motor in a steam turbine are used for maintaining the turbine's rotation during startup and shutdown phases. The turning gear main motor provides slow rotation of the turbine shaft to ensure proper lubrication and prevent thermal stress on the components. The piggy motor, often a smaller auxiliary motor, assists in this process by allowing for fine adjustments or providing additional support during low-speed operations. Together, they help maintain the integrity and longevity of the turbine system.
Steam is redirected back into the boiler from the high-pressure turbine for reheating, but the steam from the low-pressure turbine enters into a condenser to become water again.

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.
It is an engine.A steam turbine is a heat engine that uses the expansion of steam passing through stationary nozzles and blades on a shaft to turn the shaft. The steam can move through the turbine axially (one end of shaft to the other end), radially (shaft to outer casing), or tangentially (around the outer edges of the turbine wheel). In an impulse turbine, the steam is expanded in nozzles and pushes the blades. In a reaction turbine the steam is expanded in the nozzles AND in the blades, the reaction of the expansion of the steam pushes away from the blades spinning the wheel in the process. The expansion of the steam is necessary to increase its velocity through the turbine.
The servo motor is a type of motor which acts according to the command of the user. which serves the purpose of the user. therefore it is called as "servo" motor
Why extractions are taken out from steam turbine.
NO
Steam is redirected back into the boiler from the high-pressure turbine for reheating, but the steam from the low-pressure turbine enters into a condenser to become water again.
No, stepper and servo motor are by mechanical design two different types of motors.
The preventive maintenance of steam turbine mainly entails frequent servicing of the parts. This will ensure a smooth performance of the steam turbine.

Rankine cycle is used in steam turbine
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.
AC voltage, making AC current available, may be generated in several ways: * AC generator driven by * Steam turbine * Diesel motor * Petrol motor * Water turbine * Inverter from a DC source
A hydraulic piston is also known as a servo or a motor.
