对200MW汽轮机第13～15级隔板变形的原因进行了分析,提出了防止隔板变形的措施,并进行了大量隔板挠度试验,证明焊加强筋的老隔板与新设计隔板的强度和刚度能满足长期安全运行。
The reasons for the deformation of the baffles in the 13th to 15th grade of 200 MW steam turbine are analyzed. The measures to prevent the baffles from deformation are put forward. A lot of tests on the deflection of the baffles are carried out to prove the strength of the old baffle and the new baffle And stiffness to meet the long-term safe operation.
