31-25-7型汽轮机,是冲动单缸凝汽式,新蒸汽参数35绝对大汽压435℃,排汽压力0.059绝对大汽压,额定功率25000瓩,转子由一个复速级、十二个压力级共十三级组成。系由上海汽轮机厂设计并首先成批生产的一种经济性较高的中压机组。此后北京重型电机厂、武汉汽轮机厂,南京汽轮机厂亦相继生产同型机组。至今共生产五十余台,其中上汽厂产品占四十台左右。这些机组绝大部分安装在西南、西北、中南、华北等地电力系统中的各电厂。
31-25-7 type steam turbine is impulsive single cylinder condensing steam parameter 35 Absolute steam pressure 435 ℃, steam pressure 0.059 Absolute steam pressure, rated power 25000 瓩, the rotor speed by a complex, twelve A total of thirteen pressure-level composition. Department of the Shanghai Steam Turbine Design and the first mass production of a more economical medium-voltage units. Since then, Beijing Heavy Duty Factory, Wuhan Steam Turbine Factory, Nanjing Steam Turbine Factory have also produced the same type of units. So far a total of more than 50 Taiwan production, of which SAIC products accounted for about 40 units. Most of these units are installed in the power plants in the southwest, northwest, central and southern regions, and northern China.
