Description
образующих|магнига. Обе секции катушки индуктивности служат дл возбуждени |вы сокочас,готного лектромагнитного пол , а секци 5 Гложет быть и приемным элементом .forming | magnig. Both sections of the inductance coil are used to excite a very high, gothic electromagnetic field, and section 5 Gnaws to be a receiving element.
В зазоре магнита установлен цилиндри ческий каркас 7, служащий дл размещени на нем контролируемого издели 8. Каркас имеет возможность вращени вокруг центральной оси магнитарна шариках 9 A cylindrical frame 7 is installed in the magnet gap, which serves to place a controlled article 8 on it. The frame has the ability to rotate around the central axis of the magnet balls 9
Преобразователь работает следующим об разом.The converter works as follows.
Катушка индуктивности подключаетс к генератору радиоимпульсов, а секци 5 катушки индуктивности - к усилителю стандартного дефектоскопа (на чертеже не показаны ). Контролируемое изделие прот гиваетс по винтовой линии на цилиндрическом каркасе 7 и через специальные отверсти 10 во внешнем стержне 3 магнита. The inductor is connected to the radio pulse generator, and section 5 of the inductor is connected to the amplifier of a standard flaw detector (not shown). The controlled article is pulled along a helix on the cylindrical frame 7 and through special openings 10 in the outer bar 3 of the magnet.
В контролируемом изделии с помощью катушки индуктивности возбуждаютс вихревые токи, которые, взаимодейству с магнитным полем цилиндрического магнита, создают в изделии электродинамическую силу, вызывающую возникновение в изделии ультразвуковой волны. Отраженна от,де-. фекта ультразвукова волна принимаетс , например , секцией 5 катушки индуктивностиIn a controlled product, eddy currents are excited by means of an inductance coil, which, interacting with the magnetic field of a cylindrical magnet, create an electrodynamic force in the product, causing an ultrasonic wave to appear in the product. Reflected from, de-. The ultrasonic wave effect is taken, for example, by section 5 of the inductance coil.
