对厂家提供的假轴挠度进行实际测量核对,以便在转子找中时,做到正确理解,快速准确。 1前言 N125型汽轮机发电机组在国内已安装运行一百多台。其高中压转子采用整锻式转子,结构紧凑,缩短机组轴向长度,转子刚性好,叶轮强度较高,能较好地适应高温的变化,便于快速启动。改进后的N125型汽轮机额定动率可达135MW,近20000MW的装机容量是国内不可或缺的主力机组。
False shaft deflection provided by the manufacturer for actual measurement check, so that when the rotor to find out, to correctly understand, fast and accurate. 1 Introduction N125-type steam turbine generator set has been installed in China to run more than 100 units. The high and medium pressure rotors are used for the swivel rotor. The structure is compact and the axial length of the unit is shortened. The rigidity of the rotor is good and the strength of the impeller is high so that the high-pressure rotor can better adapt to the high-temperature changes for quick start. The improved rated N125 turbine rated rate up to 135MW, nearly 20000MW installed capacity is an indispensable main unit.
