The Performance Advantages of Wire Rope Nondestructive Testing Instrument Taking Weak Magnetic Testing
Wire rope nondestructive detectorThe performance advantages of weak magnetic detection are:
1. The steel wire rope adopts high strength and excellent carbon steel as the material, which has high magnetic permeability. When testing, the wire rope is excited by a magnet, and the wire is magnetized under the action of an external magnetic field.
2. Surface of signal acquisition: Hall element with high sensitivity is selected. After magnetized steel wire, any tiny △B will cause the change of electrical signal △V.
3, the characteristics of signal acquisition: broken wire signal, wear signal, external environmental impact and other different signs of the signal can be shown.
Filtering of signal acquisition: The system can filter the collected signals to ensure safety.
5. In addition to the real-time output mode, the wire rope nondestructive detector can be detected first and then downloaded, that is, the data memory is used to collect and store data on site. After the detection, the data memory is separated from the detection head and taken away from the site to facilitate data downloading.
6. Check the detection waveform in real time at the detection time. When encountering defect signals, you can stop for on-site inspection.
7. The detection waveform diagrams of the same steel wire rope at different stages can be compared with the same diagram, so as to intuitively understand the growth information of steel wire rope defects, make clear which broken wires are newly added broken wires, and which positions have an increased number of broken wires. The waveform diagrams of multiple steel wires under the same working conditions can also be compared with the same diagram to master the usage rules of steel wires.
8, wire rope nondestructive testing instrument as a measuring instrument, to ensure the accuracy and accuracy of detection is the basis. Repeatability is an important embodiment of accuracy. The results of two or more tests before and after the same wire rope with the same instrument shall be guaranteed to be complete.
9. The detection signal is the original output signal, that is, the change value of △Vd with △B, so as to ensure the authenticity of the detection signal.
After we know the performance advantages of the wire rope nondestructive flaw detector, we must consider these situations when choosing, so as to ensure the accuracy of the wire rope nondestructive testing instrument.
