Metal section loss measurement method is based on the Hall principle, the use of integral detection coil to detect. The detection method of the wire rope nondestructive detector can test the short change of the metal cross-sectional area by detecting the probe. For the flexible part of the wire rope, the overall strength of the wire rope is the local weak part with a short length.

Problems in metal section loss measurement method for wire rope nondestructive testing instrument

Metal section loss measurement method is based on the Hall principle, the use of integral detection coil to detect.Wire rope nondestructive detectorThis detection method can test the short change of the metal cross-sectional area by detecting the probe. For the flexible part of the steel wire rope, the overall strength of the steel wire rope is the local weak part with a short length.

The main problem of metal section loss measurement method is the problem of quantitative detection resolution, how to improve the resolution of the detection probe needs to be carefully studied. When using the metal section loss measurement method for quantitative detection, first select the wire rope to be detected, which is basically the same as the initial state, and the obtained detection value is used as the reference value, and then compare the measurement results of other parts with the reference value. The difference between the two is the measured value. Therefore, the selection of the reference value is the key to the accuracy of the detection results of the wire rope nondestructive detector, and it is also the center of the problem: it is difficult to determine the consistency between the state and the initial state of the wire rope that has been used for a long time.

　　Non-destructive testing of steel wire ropeThe instrument (carrying) has a wide range of applications, and can detect the static and non-moving wire rope. It can also detect the moving wire rope; That is, it is suitable for regular local flaw detection on the consumable and vulnerable parts of the wire rope in service. It is also suitable for regular and irregular inspection of wire rope.
