Direction of rotation: same as passive
Output speed: 1.7-300rpm
Output torque: 520-32000NM
During the shutdown of the unit, the steam turbine is cooled due to the cooling. Due to the uneven cooling of the upper and lower parts of the cylinder and the rotor, the rotor will undergo thermal bending after stopping the rotation.
Under such circumstances, if the steam turbine is restarted, it is easy to cause the moving and static parts to rub, and vibrations exceeding the allowable range occur. To avoid such an accident, the steam turbine is equipped with a turning mechanism.
When the electric turning mechanism is put into operation, the rotor can be continuously rotated and uniformly cooled, thereby preventing the rotor from being bent.
The condensing steam turbine must also put the turning mechanism into operation before starting the flushing, so as to avoid the bending of the rotor caused by the shaft sealing steam.
