| Abstract: | Aiming at greater vibration of couplings at both sides of low pressure cylinders of 660 MW ultra-supercritical units and generator junction box in rated rotation speed and on鄄load operation,the causes areanalyzed and relevant tests are conducted. By increasing weight of low couplings,adjusting concentricity oflow junction box and strengthening retightening force of coupling bolts,vibration of units in rated rotationspeed and full-load operation is eliminated. |
