The surface blowout preventer control device is an important equipment for controlling the wellhead blowout prevention group, hydraulic throttle valve, and kill valve. It is an indispensable device for preventing blowout during drilling and workover operations. The correct use and maintenance of the blowout preventer are very important important.
Turn the main switch of the magnetic starter on the console to the "automatic" position, the whole device is in the automatic control state, if the system pressure is lower than 19MPa, the pressure controller will automatically start the oil pump, and the pressure oil will flow to the accumulator through the one-way valve. Group oil supply, when the system pressure reaches 21Mpa, the pressure controller will automatically cut off the power supply to stop the electric oil pump.
Turn the main switch of the magnetic starter on the console to the "manual" position, the oil pump will not stop automatically when the pressure is reached, and stop manually when needed.
