Abstract
Изобретение относитс к дефектоскопии ферромагнитных изделий и может ь использовано дл отметки дефектных меа на поверхности объектов в труднодоступных меаах и в жидкой среде. Цель изобретени - расширение функциональных возможноаей способа отметки мест с дефектами достигаетс благодар тому, что на поверхность корпуса отметчика со стороны объекта 2 jjaнoc т магнитную крас щую жидкоаь 4, удерживают ее магнитным полем, силовые линии которого направлены в исходном еоао нии параллельно пооерх- ноаи объекта а во врем нaнece и метки измен ют направление силовых линий магнитного пол на ортогональное. 2и/1The invention relates to a flaw detection of ferromagnetic products and can be used to mark defective materials on the surface of objects in hard-to-reach materials and in a liquid medium. The purpose of the invention is the expansion of the functional possible way of marking places with defects due to the fact that the magnetic paint liquid 4 is held onto the surface of the marker body from the side of the object 2 by holding it with a magnetic field, the lines of force of which are directed in the initial direction parallel to the surface of the object and at the time of the tide, the marks also change the direction of the magnetic field lines to orthogonal. 2i / 1

Изобретение относитс к дефектоскопии и может быть использооано дл отметки дефектных мест на поверхности издели в труднодоступных местах.The invention relates to flaw detection and can be used to mark defective spots on the surface of a product in hard to reach places.
Целью изобретени вл етс расширение функциональных возможностей способа путем отметки дефектных мест в жидкой среде.The aim of the invention is to expand the functionality of the method by marking defective locations in a liquid medium.
На фиг.1 показан отметчик в исходном состо нии; на фиг,2 - то же, в момент нанесени метки.Fig. 1 shows a marker in the initial state; Fig. 2 is the same at the time of marking.
Отметчик содержит корпус 1. размещаемый над объектом 2 с зазором, источник посто нного магнитного пол - магнит 3, магнитную жидкость 4, размещенную на внешней поверхности корпуса отметчика в зазоре между корпусом 1 и объектом 2.The marker contains a housing 1. placed above the object 2 with a gap, the constant magnetic field source is a magnet 3, a magnetic fluid 4 located on the outer surface of the marker housing in the gap between the housing 1 and object 2.
Способ осуществл етс следующим образом .The method is carried out as follows.
Размещают отметчик оппозитно объекту 2 с зазором относительно последнего. В исходном состо нии магнит ориентирован параллельно рабочей поверхности корпуса и одновременно параллельно поверхности объекта. При этом магнитна жидкость принимает форму, показанную на фиг.1. При поступлении сигнала об отметке дефектного места измен ют положение магнита 3 наPlace a marker opposite to object 2 with a gap relative to the latter. In the initial state, the magnet is oriented parallel to the working surface of the housing and simultaneously parallel to the surface of the object. In this case, the magnetic fluid takes the form shown in Fig. 1. When a signal is received about the mark of a defective place, the position of magnet 3 is changed to
