轮对的超声波探伤,是一种轮对轮座部位不退轮的有效检查方法。目前,这种对轮对内外侧四处超探的检查方法,各段都有不同之处。有的是将轮对在固定超探线上来回滚动,这样,探伤一对轮对需要将轮对在超探线上来回往返四次才能完成。另一方面,涂在车轴上的机油也无法回收,全部滴在超探线上,既浪费机油,又造成工作场地的污染。 Ultrasonic testing of the wheelset is an effective inspection method for the wheel without seat on the wheel seat. At present, this method of inspecting four rounds of the inside and outside rounds of the wheel is different from each other. Some are rolling the wheel back and forth on a fixed overturning line, so flaw detection of a pair of wheels in the overtaking on the need to round trip back and forth four times to complete. On the other hand, the oil coated on the axle can not be recovered, all drops on the super-exploration line, both waste oil, but also cause workplace pollution.
