Turning Gear of MGT-75 Gas Turbine
Application:
Starting up the rotor of gas turbines Uniform cooling of the rotor when turning off the turbine
Product Introduction:
Before starting the gas turbine, its rotational speed should be brought to a certain limit where the burners are turned on, so that they can slowly heat the turbine by heating the compressed air coming from the compressor. This rotor is started by a device called Turning Gear. Turning gears are designed and manufactured in 3 ways according to the speed and torque: Pelton turbine mechanism, torque converter or pinion and gear wheel. Pelton turbine mechanism is outdated and is not used in modern power plants.
Also, due to the heavy mass of the rotor of the turbines, special attention should be paid to the issue of uniform thermal conduction in its longitudinal and radial directions, because the non-uniformity in the cooling of the rotor causes thermal stresses and, as a result, bending and changing its shape. To prevent this, when the rotational speed of the rotor reaches a certain number, the turning gear is engaged and rotates the rotor for a certain period of time (6-8 hours) to cool down evenly.
