Description
Ток подают с йГсточника 4, блок 3 реверса однократно реверсирует его, вследствие чего гальвано чейка 2 пол ризуетс положительно, а элемент 1 - отрицательно, и на его поверхности окисел восстанавливаетс . Под действием , положительного потенциала с гал вано чейки 2 на выходе порогового элемента 5 по вл етс напр жен}1е, и ключевой элемент б не пропускает импульсы с генератора 7 на преобразователь 8 и счетчик 9, т.е. во врем реверса тока показани счетчика не мен ютс . По окончании реверса блок 3 ревер са мен ет направление тока на основное и начинаетс анодное растворение покрыти с элемента 1. На выходе порогового элемента 5 напр жение отсутствует , и ключевой элемент 6 про пускает импульсы от генерато.ра 7 импульЬов на вход преобразовател 8 импульсов. Коэффициент преобразовани пoдoбpiaн такой, ч:то на вход сче чика 9 поступают импульсы, соответствующие единице толщины покрыти , т.е. сче.тчик показывает значение толщины покрыти , снимаемого с элемента 1. В момент.полного сн ти покрыти на всю толщину возникает изменение амплитуды скачок) напр жени на гальвано чейке 2, которое воздей ствует на пороговый элемент,5. На выходе порогового элемента по вл ет с .напр жение, поступающее на вход ключевого элемента б, он закрываетс , а импульсы от генератора 7 импульсов не проход т на преобразователь Вина счетчик 9.The current is supplied from the source 4, the reverse unit 3 reverses it once, as a result of which the galvanized cell 2 is positively positive, and the element 1 is negative, and the oxide on the surface is reduced. Under the action of a positive potential with a galvan cell 2 at the output of the threshold element 5 appears voltage} 1e, and the key element b does not transmit pulses from the generator 7 to the converter 8 and the counter 9, i.e. during current reversal, the meter reading does not change. When the reverse is completed, the reverse unit 3 changes the direction of the current to the main and the anodic dissolution of the coating starts from element 1. At the output of threshold element 5, there is no voltage, and key element 6 sends pulses from generator 7 pulses to input of converter 8 pulses. The conversion coefficient of the product is as follows, h: then impulses corresponding to the unit thickness of the coating, i.e. the slider shows the thickness of the coating removed from element 1. At the moment of complete removal of the coating, the amplitude of the jump jumps across the galvanized cell 2, which affects the threshold element, 5. At the output of the threshold element, a voltage arrives at the input of the key element b, it closes, and the pulses from the pulse generator 7 do not pass a counter 9 to the Wien converter.
