Description
При этом второй элемент запоминани вычисл ет разность АЯа-А ьIn this case, the second memory element calculates the difference АЯа-А Ь
На основе знака разности APj-A i элемент задержки 6 определ ет направление вращени исполнительного механизма 2.Based on the sign of the difference APj-A i, delay element 6 determines the direction of rotation of actuator 2.
При ДР4-АРз (разность отрицательна ) исполнительный механизм 2 делает реверс и уменьшает давление с Р Р до Р Рз, что соответствует максимуму скорости бурени .With ДР4-АРз (the difference is negative), the actuator 2 reverses and reduces the pressure from Р Р to Р Рz, which corresponds to the maximum drilling speed.
