All models of control system are equipped with double pump systems. Even if there is no electricity, the remote control panel can still function normally.
The pump system is equipped with the automatic starting and stopping system. With dual safety protection desigh, The system will overflow and discharge when the system setting pressure is exceeded.
The energy stored in the accumulators is high enough to complete closing and opening of BOP several times without the oil pump working.
The accumulator has construction of large upper port, easy to remove and install bladders through the sopt. Adding accumulator ball valve makes it is convenient to change and maintain accumalotor while the system is operating.
The driller's panel is easy to operate. Because of its simple structure, it can be put on any convenient position on drill floor and opening or closing the BOP at any time.
The protection house makes the remote control panel waterproof and dustproof. It can also prevent others from mis-operating
