Abstract
The utility model discloses an automatic eddy current flaw detection device, which comprises a flaw detector and a computer, wherein the flaw detector and the computer are connected through a probe wire, and a probe of the flaw detector is opposite to a pipe product subjected to straightening output. The automatic eddy current flaw detection device disclosed by the utility model is high in automation degree and detection efficiency and accurate for detection.
Description
Technical field
The utility model relates to a kind of not damaged failure detector of tubing, especially a kind of automatic eddy-current crack detector.
Background technology
Produced tubing need to detect the phenomenons such as whether fluid welding, perforation, scuffing are arranged.At present, the device category of flaw detection usefulness is a lot, but ubiquitous deficiency is that automaticity is low, and efficient is not high.For adopting the continuously out very difficult adaptation of the detection of tubing of automatic production line.
The utility model content
The purpose of this utility model provides the automatic eddy-current crack detector that a kind of automaticity is high, detection efficiency is high.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of automatic eddy-current crack detector, comprise defectoscope, computer, and wherein, be connected by probe wire between described defectoscope and the computer, the probe of this defectoscope is facing to the tubing through alignment output.
Preferred technical scheme is that computer is placed on the support.
After the utility model adopts said structure, couple together with computer by popping one's head in, by the excitation of computer control defectoscope, reception, amplification, filtering, phase demodulation, zero potential balance etc., the anti-resistance figure that observes computer screen changes, and utilizes the difference at impedance diagram phasing degree can distinguish the character of defective; This automatic degree of failure detector by computer control flaw detection is high, detection efficiency is high, and detects accurately.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the utility model perspective view.
Among the figure: 1 defectoscope, 2 computers, 21 screens, 3 probe wires, 4 tubing, 5 supports.
Embodiment
Shown in Figure 1, automatic eddy-current crack detector of the present utility model comprises defectoscope 1, computer 2, wherein, is connected by probe wire 3 between described defectoscope 1 and the computer 2, and the probe of defectoscope 1 is facing to the tubing 4 through alignment output.Above-mentioned computer 2 is placed on the support 5.
During use, ⑴ connects power lead and probe wire 3, and opening power is opened eddy current flaw detec 1; ⑵ will pop one's head in by the artificial defect of sample pipe (can with reference to GB: the flaw detection sensitivity of general pipe is the perforation about ф 0.8～ф 1.5 ㎜), see the impedance diagram of screen 21 this moment, whether reach the requirement of sensitivity, as do not meet, change the yield value of parameter and press school zero; ⑶ control phase, make its rotate to own want to set the angle position; ⑷ change the relevant parameters in the parameter, if to the work of required check by probe 11, observe the variation of impedance diagram, utilize the difference at impedance diagram phasing degree can distinguish the character of defective.
Finish using, use dust cover and build, should often instrument be opened 1～2 hour, disperse moisture.
The above is preferred implementation of the present utility model; certainly can not limit with this interest field of the utility model; should be understood that; for those skilled in the art; the technical solution of the utility model is made amendment or is equal to replacement, do not break away from the protection domain of technical solutions of the utility model.
