The inter-electrode type magnetic flaw detector

摘要

(57) Abstract Objective Not to make the flux density decrease which enters into inspected ones, inspectionEfficiency it improves. Constitution It magnetizes welding structure 1 by turning on electricityru N₁, N₂, S₁, 4 polar magnetizers 2 which consist of S₂ and magnetismThe spring it has 3 which, supports conversion vessel 2 and caster 4 suThrough pulling 3, the movable cart 5 which supports magnetizer 2 and,It possesses. As for magnetizer 2, iron of lower part of iron core 2of a letter die of koWith the structure which winds the coil around heart 2b, at the time of power source off the tableThe gap 2 - 3mm is caused with the surfaces 1a. Power source suppliesWhen it is done, iron core 2a is adsorbed by surface 1a by magnetic force,It fits to the lever re. Advantages When inspecting make with pole and the object to be tested fitWith, to prevent the decrease of flux density, in enlargement of the inspection rangeIt is possible to assure the improvement of ru inspection capacity.
