After the rotor of steam turbine NO.2 being bent to 0.135mm in Huayang Power-Generation Company

for solving problems

such as shaft vibration at bearing shoe NO.1 surpassing standard value in the course of starting impingement

existence of colision-wear vibration at bearing-shoe NO.4 and vacuum leak of low pressure shaft seal in operation

as well as the efficiency of high -and medium-pressure cylinders deviating from designed values e+c.

combined with the features of self-adjusted gland-packing

the flow passage of steam turbine NO.2 has been retrofitted

obtaining comparatively satisfactory effectiveness.
