Description
(54) УСТРОЙСТВО УПРАВЛЕНИЯ ПРОЦЕССОМ БУРЕНИЯ(54) DRILLING CONTROL DEVICE
пример, с помощью сменных лекал. Выходной сигнал функционального преобразовател 2, пропорциональный величине оптимальной скорости вращени , соответствующей текущему значению скорости подачи на элементе сравнени 6, алгебраически суммируетс с выходным сигналом датчика 4 действительной скорости вращени долота. Выходной сигнал (рассогласование) элемента сравнени 6 поступает на вход регул тора 7 скорости вращени долота. Если вибраци станка превышает некоторый критический уровень, на элемент сравнени 6 встречно с выходным сигналом преобразовател 2 дополнительно поступает сигнал с вибродатчика 5, т. е. осуществл етс корректировка режима по вибрации.example, using replaceable patterns. The output signal of the functional converter 2, which is proportional to the magnitude of the optimum rotational speed corresponding to the current value of the feed rate at the reference element 6, is algebraically summed with the output signal of the sensor 4 of the actual bit rotation speed. The output signal (mismatch) of the element of comparison 6 is fed to the input of the regulator 7 of the bit rotation speed. If the machine vibration exceeds a certain critical level, the element 6 of the counter 6 with the output signal of the converter 2 is additionally supplied with a signal from the vibration sensor 5, i.e. the vibration mode is adjusted.
Контур онтимизации осевой нагрузки работает аналогично онисанному выше контуру. Выходной сигнал многофункциональпого преобразовател оптимальной осевой нагрузки от скорости подачи поступает па элемент сравнени 10, где алгебраически суммируетс с выходным сигналом датчика 8 действительной осевой нагрузки и датчика 9 тока кор двигател вращени (который срабатывает лишь при превышении токомкритической величины ). Выходной сигнал (рассогласование) элемента сравнени 10 поступает на вход регул тора 11 осевой нагрузки, который обеспечивает стабилизацию заданной оптимальной осе вой нагрузки.The contour of the onimization of the axial load works in the same way as the contour above. The output signal of the multifunctional converter of the optimal axial load from the feed rate comes in comparison element 10, where it is algebraically summed with the output signal of the sensor 8 of the actual axial load and the sensor 9 of the rotation motor core (which works only when the critical value is exceeded). The output signal (mismatch) of the element of comparison 10 is fed to the input of the axial load controller 11, which provides stabilization of the specified optimal axial load.
Таким образом, устройство позвол ет автоматически поддерживать оптимальный по кри5 терию экономичности режим бурени при произвольном сочетании буримых пород.Thus, the device allows you to automatically maintain a drilling regime that is optimal in terms of efficiency, with an arbitrary combination of drilled rocks.
