QJPC-S/X-type steam turbine electric maintenance turning gear is a special maintenance equipment used in the maintenance of steam turbines in large thermal power plants. When the power plant is shut down to overhaul the steam turbine unit, the use of this equipment can improve the maintenance quality, shorten the maintenance period, reduce the labor intensity, abolish the traditional method of pulling the steam turbine rotor with steel wire rope, and improve the safety of the maintenance work.

(1) The design of the QJPC-S top-mounted maintenance turning gear is simple and beautiful, and the small gear meshes with the large gear on the upper part of the middle part of the cylinder. The rotor can be rotated forward and reverse continuously or inching.

(2) The installation is convenient, and the equipment is fixed on the position of the original working turning device. Adjusting the movable box body can make the pinion in the movable box body and the large gear on the turbine rotor in a convenient meshing or separation state, so that the turbine rotor can be lifted out of the cylinder freely.

(3) After the turbine rotor is in place, the control box button can be moved in reverse to release the force, so that the turbine rotor can be easily in a free state. Ensure that the measurement data is true and accurate.

(4) The portable electric control box is small, light, flexible in operation and large in moving range.
