SUN-I Mobile Ultrasonic Flaw Detector for Hollow Axles
1. Brief introduction:
The SUN-I Mobile Ultrasonic Flaw Detector is an automated non-destructive testing (NDT) device specifically designed for detecting surface fatigue defects and internal volume defects of EMU hollow axles. It is a core maintenance equipment for high-speed rail safety, and also applicable to locomotive manufacturing plants and metro (hollow axle) inspection fields. The device features independent R&D core technology, compact structure and high detection accuracy.
