The invention discloses a
steam turbine unit mounting technology, and belongs to the technical field of
steam turbine mounting. The problems that in the prior art, the quality of a
steam turbine unit mounting technology is difficult to control, and consequently frequent maintenance is caused is solved. The steam
turbine unit mounting technology comprises the following steps of technological preparation,
sizing block arrangement, front bearing seat mounting, lower cylinder mounting, partition plate mounting, rotor mounting, cylinder longitudinal and transverse horizontal correction, pre-buckling of a large cover on a steam
turbine, generator bearing mounting, generator bearing seat mounting, generator rotor checking and hoisting, coaxiality aligning of the steam
turbine and a generator, generator
stator bedplate mounting, generator
stator mounting, generator rotor penetrating, air gap and magnetic center adjusting, bearing bush gap and tightening force adjusting of a steam turbine and generator unit, buckling of the large cover on the steam turbine, secondary grouting of the unit, cleaning, checking and re-mounting of a speed regulating
system, bearing box covering, turning gear mounting and adjusting and grouting. According to the technology, the quality of the technological process is strictly controlled, and the stability and safety of the technology are remarkably improved.
