AIR GUN FOR INSPECTING EDDY CURRENT

摘要

PURPOSE: An air gun for inspecting an eddy current is provided to enhance the reliability of the inspection by uniformly maintaining the reverse moving velocity of an inspection member inserted in a heat exchanger tube. CONSTITUTION: The air gun for inspecting an eddy current makes the inspection member move in order to inspect an eddy current generated from an interior of a heat exchanger tube. A handle body(56) has a handle housing(52) of which a driving shaft rotates with the aid of an air pressure in the handle housing(52). A loading member(102) is positioned onto an upper portion of the handle body(56). A drawing body(64) having the first and the second drawing members(60,62) is mounted onto the center upper surface of the loading member(102) in order to move a cable in a reverse direction. An injection body(68) has an injection nozzle(66) for injecting air with receiving the cable is formed at one side of the drawing body(64). A cable guide body(70) for smoothly transferring the cable is formed at the other side of the drawing body(64).
