常见风电叶片问题及风电叶片检查方案目录catalog 01常见叶片问题及检查方法Blade inspection methods02介绍及案例展示CobotAI-B1 introduce and inspection case风电叶片容易受到强风、雷击、疲劳的影响，引起风电叶片结构损伤；且由于出厂质量影响，有些缺陷长期存在，影响叶片的可靠性。
Wind turbine blades easily affected by strong winds, lightning, fatigue, caused blades damage ; And because of the influence of the factory quality, some defects exist for a long time, the influence on the reliability of the blade随风机运行时间增长，叶片维修需求增加，但普通叶片检查只能查出表面缺陷，存在隐患，所以需要开展叶片无损内部检测。
Grow along with the running time, blade repair demand increases, but blade visual inspection only can be found surface defect, so need for a nondestructive internal inspection.分类人为检测仪器检测检测方式Inspectionway人工目测、敲击、单反相机远距拍照visual inspect , knock, take picture超声无损检测Ultrasonic红外无损检测infrared特点Feature 简单，直接，易于操作，成本较低。
