Double track ultrasonic flaw detection vehicle
The double track ultrasonic flaw detection vehicle adopts a fully self-developed parallel UT processing technology to realize non-destructive flaw detection of double-sided rails and supports up to 32 channels of ultrasonic signal processing. The flaw detection equipment adopts a wheel-type integrated probe structure. A plurality of piezoelectric crystal probes with different angles are integrated and installed in the probe wheel. At the same time, the ultrasonic signal is activated and echo signal is received, so that the accuracy of flaw detection is high, and it is suitable for high-speed rail, existing lines, subways, light rails and all rail lines.
Testing in Eastern Suburbs of CHINA

（1）Wide range of applications: Suitable for all rail lines of high-speed rail, existing lines (passenger, freight), subway and light rail; compatible with all rail types 43-75kg/m.
（2）Strong environmental adaptability: it could work in small rain, snow, night, maximum 175mm superelevation, minimum 160m curve radius and 35 ‰ gradient operation, -25 °C low temperature operation.
（3）The detection speed is fast: the flaw detection speed is 5-15km/h, and the non-working speed is 20km/h.
（4）High precision of flaw detection: 10 probes on one side, the sampling interval is less than 3mm, which guarantees the precision of flaw detection.
