What are the main operating principles of the blowout preventer control device?

The blowout preventer control device at the drilling and workover site is an important device for operating the blowout preventer group and the throttle and crushing hydraulic control valve switch. BOP control device is an essential safety device in drilling and workover operations. After the blowout preventer, accidental operation of the drill winch will cause damage to the blowout preventer core and breakage of the drill rod from time to time. From the perspective of ensuring the safety of the equipment itself, combining the working principle of the winch and the blowout preventer control device, we find both. According to the working principle of the anti-collision crane of the drilling drawworks, the hydraulic control oil of the blowout preventer is used to control the opening/closing of the hydraulic control check valve, and it is connected in parallel with the anti-collision crane.

After closing the blowout preventer, the drilling drawworks will automatically brake and the high and low speed clutch valves of the drilling drawworks cannot be operated to prevent serious accidents caused by misoperation. When the gate valve blowout preventer is opened, the drilling winch is no longer restricted by the blowout preventer control device. run.

The BOP control device consists of two power modes: gas and electric. Provides a hydraulic power source for the system and stores it in 16 energy storage bottles. Under the action of corresponding pressure adjustment and three-position four-way reversing valve, different pressures can be achieved. The hydraulic oil is delivered to the blowout preventer group to realize the function of opening and closing the blowout preventer group. The hydraulic oil collection point of the hydraulic control check valve discussed in this article comes from the automatic braking of the drilling rig when the blowout preventer is closed. Under normal circumstances, always keep raising and lowering the speed of the cruise ship.
