高水头的混流式转轮、水泵转轮和水泵水轮机转轮的先进制造工艺(以前仅用于冲击式水轮机)的发展引领一场转轮制造技术的创新。这成就了转轮制造过程的良好可达性、转轮质量的提升和电站营运的良好效益。本文聚焦转轮制造新工艺的发展、不同的工程应用以及其比较优势,特别是其在高水头转轮制造的比较优势。高水头转轮流道形状复杂,机械加工和铲磨的可达性受到几何结构的限制。整铸或铸焊(叶片、上冠、下环分别铸造后焊接成形)等传统制造工艺难于凑效。对于此类高水头转轮,本文展示的先进制造工艺具有明显的优势。 The development of advanced manufacturing processes for high head Francis, pump and pump turbine runners (formerly used only for impulse turbines) led to an innovation in wheel manufacturing technology. This completes the good reachability of the wheel manufacturing process, the improvement of runner quality and the good profitability of plant operation. This article focuses on the development of new processes for wheel manufacturing, different engineering applications, and their comparative advantages, especially their comparative advantages in the manufacture of high head rotors. High-head runner flow path complex shape, machining and shovel access by geometry constraints. Casting or cast welding (blade, the crown, the ring after the casting were separately formed by welding) and other traditional manufacturing technology is difficult to make ends meet. For such high-head runners, the advanced manufacturing processes demonstrated in this article have significant advantages.
