摘要:

 水轮机叶片是水轮机发电机组中的核心部件,由于工作的强度和环境影响,叶片极易磨损并且难以修复,更换叶片则成本巨大,故有效地对叶片进行修复则尤为重要。通过便携式三坐标测量机系统可对缺陷叶片进行逆向工程扫描,确立三维模型,还原其原始特性。根据系统软件处理三维比对得出叶片的缺陷部位偏差,从而进行修复指导,通过实践,证明三坐标测量机系统能对叶片修复给予指导并达到良好效果。

Abstract:

Cavitation erosion and abrasion will bring about damage, deformation, and crack to hydroturbine blades. A portable three-coordinate measuring machine was employed to repair the defects. Infinite 2.0 six-axis portable 3-D measuring machine was used as the hardware carrier. Software ScanWorks, Geomagic Studio, Geomagic Qualify and CAD were built in the machine. Through this measuring machine, reverse engineering scanning, 3-D spatial measurement, data visualization, 3-D modelling, point-cloud data analyzing and processing, and data conversion were carried out. By comparing the original 3-D model with the defective model, location and size of the defects were obtained. The three-coordinate measuring machine is accurate, and is of guiding importance for the repair of hydroturbine blades.

Key words: portable three-coordinate measuring machine, hydroturbine, blade, repair
