| Abstract: | 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. |
