the external connection end face of an air inlet flange of a rotor and turbine semi-finished product assembly is downwards arranged on a turbine shell adjusting base plate (9) and is arranged by using turbine shell fixing screws (10), before a guide shaft lever (3) is not connected with the external shaft supporting end of the rotor, the turbine shell fixing screws (10) are in an untwisted state, at the moment, the guide shaft lever (3) extends rightwards, the supporting end of the external shaft of the rotor is inserted into a connecting hole at the front end of the guide shaft lever (3), then the turbine shell fixing screws (10) are tightened, and clamping of the rotor and the turbine semi-finished product assembly is completed;
when the stator and the rotor are assembled together, the guide shaft rod (3) is held, the hand wheel (20) is rotated, the screw nut (14) is driven by rotating the ball screw (13), the rotor and the turbine semi-finished product assembly are driven by the turbine shell sliding bracket (8) to move leftwards along the linear guide rail (11) through the sliding block (12) and are installed in a stator central shaft hole in the casing, the rotor shaft extends outwards until the rotor shaft extends into a corresponding supporting bearing of the generator casing, the turbine shell and the turbine generator casing are fastened by the fixing screws for the involutory connecting flange, and the assembly of the stator and the rotor of the turbine generating equipment is completed.
