摘要
由超声传感器、反射镜和旋转机构等组成的微型探头 ,可伸进内径为 1 0～ 70 mm的小管道 ,用水浸方式对管道进行扫描检查 ,并将信号传向探伤仪或计算机 ,实现对管壁厚度、内外壁损耗。
The micro- probe com posed of ultrasonic transducer,reflector and rotating elem ent can be used to do im mersion scanning in the small tubes with 10～ 70 m m inner diam eters,by which signals can be transfered to instrument or m icrocomputer to test the tube wall thickness,the loss and cracks of inner and outer surfaces of tubes and other parameters.
