对低压缸刚度提出自己的观点:在工作频率下低压缸轴承座的动刚度是低压缸各种刚度中最关键的因素。提供了运行中低压缸热变形、抗轴向变形刚度及上汽缸刚度等电厂实测与模型试验数据,以证实上述观点。指出,只要在自然状态下各段转子中心对正,整个中心线成为一条光滑的挠曲线,即可解决安装时转子找中的问题。还列举了一些数据表明,我厂低压缸上汽缸刚度足够,且在启动运行中低压缸抗轴向变形刚度也颇可靠。
On the low-pressure cylinder stiffness put forward their own point of view: the operating frequency of low-pressure cylinder bearing dynamic stiffness of the low-pressure cylinder stiffness is the most critical factor. It provides data of actual measurement and model test of power plant such as low-pressure cylinder thermal deformation, anti-axial deformation rigidity and upper cylinder rigidity in operation, so as to confirm the above viewpoints. It is pointed out that as long as the center of each rotor in the natural state is aligned and the entire center line becomes a smooth curve, the problem of finding a rotor during installation can be solved. Also cited some data show that my factory low-pressure cylinder cylinder stiffness is sufficient, and in the start-up operation of low-pressure cylinder axial deformation stiffness is also quite reliable.
