Электросхема нивелира включает источник питани 9, кпопку пуска 10, реле 11 с двум нормально разомкнутыми контактами, реле 12 с нормально замкнутыми контактами, электродвигатель с жестко закрепленной на его выходном валу электромагнитной муфтой 6, обмотка которой последовательно соединена с нормально замкнутыми контактами реле 12.The circuitry circuit includes a power source 9, a start button 10, a relay 11 with two normally open contacts, a relay 12 with normally closed contacts, an electric motor with an electromagnetic clutch 6 rigidly fixed on its output shaft, the winding of which is connected in series with the normally closed contacts of relay 12.
При включении кнонки 10 срабатывает реле 11, его контакты замыкаютс , один из которых блокирует кноику пуска 10, а другой подготавливает цепь игольчатого электрода 4. Одновременно включаютс электродвигатель 5 и муфта 6, котора , преодолева действие пружины 8, опускает шток 3. В момент касани иглы 4 поверхности рабочей жидкости 2 замыкаетс цепь игольчатого электрода , при этом срабатывает реле 12, его нормально замкиутые контакты, размыка сь, отключают питание электродвигател 5 и муфты 6, а шток 3 под действием пружины 8 возвраш ,аетс в исходное положение.When the button 10 is turned on, the relay 11 is activated, its contacts are closed, one of which blocks the start button 10, and the other prepares the needle electrode circuit 4. At the same time, the electric motor 5 and the coupling 6 turn on, which, overcoming the action of the spring 8, lowers the rod 3. At the moment of contact the needles 4 of the surface of the working fluid 2 closes the needle electrode circuit; in this case, the relay 12 is activated, its normally closed contacts open, disconnect the power supply to the electric motor 5 and the coupling 6, and the stem 3 returns to the origin of the spring 8 Noah position.
Поскольку цепь электропривода посредством реле 12 разомкнулась, контакты реле II, блокирующие кнопку 10, отключаютс . Дл повторени цикла необходимо вновь включить кнопку 10.Since the circuit of the electric drive by means of the relay 12 has opened, the contacts of the relay II blocking the button 10 are turned off. To repeat the cycle, the button 10 must be turned on again.
Таким образом, устройство обеспечивает кратковременный контакт игольчатого электрода с рабочей жидкостью. Это дает возмож4Thus, the device provides short-term contact of the needle electrode with the working fluid. This makes it possible4
ность производить измерени практически без ограничени скорости опускани njTOKa, то есть с высокой производительностью и значительным уменьшением коррозии и электроэрозии игольчатого электрода.The ability to measure practically without limiting the rate of descent of the njTOKa, i.e., with high productivity and a significant reduction in corrosion and electroerosion of the needle electrode.
