A tool for applying couplant for ultrasonic flaw detection of porcelain bottles

Abstract

The invention discloses a special tool for applying an ultrasonic flaw detection coupling agent to a porcelain bottle, and relates to an applying tool. The conventional coupling agent applying manner is realized by manually extruding the bottle of the coupling agent at present, so that the applying of the coupling agent is relatively not easy and nonuniform, and the detecting operation is difficult. The special tool disclosed by the invention comprises a spray head, a hose, a coupling agent container and a power source, wherein the spray head is connected to the coupling agent container through the hose, and the flow of the coupling agent in the hose is controlled through the power source; the spray head comprises a flat rectangular spray nozzle and a cylindrical liquid inlet, the side surface of the spray nozzle is stuck onto the side surface of an ultrasonic probe for flaw detection of the porcelain bottle, the front end of the spray nozzle is aligned with the front end of the ultrasonic probe, the width of the spray nozzle is greater than the detection width of the ultrasonic probe, and the liquid inlet of the spray head is embedded in the hose. According to the technical scheme, the quick, uniform and immediate applying of the ultrasonic flaw detection coupling agent to the porcelain bottle is realized.

Description

Technical field [0001] The invention relates to a smear tool, in particular to a couplant smear tool for ultrasonic flaw detection of porcelain bottles. Background technique [0002] At present, non-destructive testing projects are increasingly being used in the production practice of the electric power industry. Porcelain bottles are widely used as insulating materials in the power system. Due to the impact of vibration and force on the porcelain bottles due to transportation and installation, it is judged whether there is any inside. Damage becomes very difficult. Ultrasonic flaw detection is gradually being promoted and applied in porcelain bottle flaw detection projects with its unique advantages. Ultrasonic testing needs to use a couplant to remove the air between the probe and the measured object, so that the ultrasonic wave can effectively penetrate the measured object to achieve the purpose of effective detection. At present, the conventional couplant application method...

AI Technical Summary

Problems solved by technology

At present, the conventional couplant application method is realized by manually squeezing the couplant bottle. Since the installation position of the porcelain bottle is relatively high, and the detection space near the upper and lower flanges is relatively small, the application of the couplant becomes relatively difficult and uneven, and due to There is a time difference between couplant application and probe detection, and the couplant will hang down and be lost, which brings difficulties to the detection work
