Product Description

This BOP- stacks control system is an important equipment for controlling BOP stacks, choke and kill valve for well control. The products are API SPEC *6D certified. The system is equipped with two pump groups. Electric pump with different flow rate, and air-operated oil pump which ensures the system to work normally in case of power failure. The design of accumulator unit meets the requirement of closing all BOP stacks and opening hydraulic valve. If any accumulator bottle failed, the total liquid loss will not exceed *5%. The pressure of annular preventer circuit in controlsystem may be adjusted by remote air-operated regulation. It characters reverse adjusting. In case of sudden failure of air supply, the pressure can be reset to the initial set value automatically. The control manifold of the remote control panel is equipped with an orifice as an inlet of the pressure source. For example, the nitrogen backup system offered by us provides emergent auxiliary energy. If the accumulator and/or the pump cannot provide the control manifold with enough power fluid, the nitrogen backup system may be used to provide high-pressure air to close the preventer.The nitrogen backup system may provide emergency air supply for the driller's panel and the auxiliary control panel. The system may be proided with an alarm device. It monitors the accumulator pressure, air supply pressure and the liquid level in oil tank. When the above parameters exceed the alarm limits, the signal of sound and light will be given.
