Description
(54) УСТРОЙСТВО УПРАВЛЕНИЯ ГИДРОПОДЬЕМНИКОМ БУРОВОЙ УСТАНОВКИ(54) DEVICE CONTROL DEVICE FOR HYDRAULIC DRILL EQUIPMENT
левого цилиндра 6 давление, которое -обеспечивает -перемещение Konijpa механизма измерени скорости 3, задева величину скорости спуска, при подаче жидкости управлени в рабочую полость 8 цилиндра сервоуправлени 2. При этом давление из рабочей полости 9 силового цилиндра 6 через клапан S поступает в полость управлени распределител 4 и он отсекает рабочую полость 8 цилиндра сервоуправлени 2 от маслобака 7. При ппадании колонны в процессе спуска на уступ в скважине происходит падение давлени в рабочей полости 9 силового цилиндра б, распределитель 4 переключаетс и сообщает с маслобаком 7 рабочую полость 8 цилиндра сервоуправлени 2 и он не преп тствует перемещению дросселирующего клгшана 1 под действием его пружины, который перекрывает слив из рабочей полости 9 силового цилиндра б и он останавливаетс .the left cylinder 6 pressure, which provides a displacement of the speed measuring mechanism 3 Konijpa, affecting the value of the speed of descent, when the control fluid enters the working cavity 8 of the servo control cylinder 2. The pressure from the working cavity 9 of the power cylinder 6 through valve S enters the control cavity the distributor 4 and it cuts off the working cavity 8 of the cylinder of the servo-control 2 from the oil tank 7. When the string collapses during the descent to the ledge in the well, pressure drops in the working cavity 9 of the power cylinder b, the distribution The engine 4 switches and communicates with the oil tank 7 the working cavity 8 of the servo control cylinder 2 and it does not prevent the throttling valve 1 from moving under the action of its spring, which blocks the drain from the working cavity 9 of the power cylinder b and it stops.
