650MW核电汽轮机P型叶根叶片装配工艺研究

Study on Assembly Process of Blade with P Type Root for 650MW Nuclear Turbine

对 6 5 0MW核电汽轮机自带围带叶片及自由叶片装配工艺过程进行详细论述。通过对P型叶根自带围带叶片及自由叶片辐射线的测量与控制 ,使叶片叶根两侧承力面接触紧密、受力均匀 。

This paper expounds the assembly of integral-shrouded blade and free standing blade for 650MW nuclear turbine. By measuring and controlling the radial line of free standing blade and integral shrouded blade with P type root, we can make the load-carrying surface on both sides of root tightly contacted and evenly loaded, thus precisely ensures the through-flow clearance.
