    • A chemical injection system includes a pump in fluid communication with a chemical reservoir and a pipeline; a motor coupled to the pump and adapted to drive the pump to transfer a chemical fluid from the reservoir to the pipeline; a motor controller electrically coupled to a power module and the motor and adapted to adjust a rotational speed of the motor; and a central controller communicably coupled to the motor controller and a remote computing device. The controller includes a translator adapted to receive a signal from the remote computing device in a first communication protocol and translate the signal from the remote computing device to a command in a second communication protocol distinct from the first communication protocol, where the command is operable to adjust the motor controller to adjust the rotational speed of the motor.

    • An apparatus and method for injecting a fluid such as a chemical corrosion inhibitor into a pipeline is provided. A solar panel is supported by a support structure in the vicinity of the pipeline location for converting solar energy to electrical current. The solar panel is electrically connected to an electrical storage battery through a voltage regulator that regulates the current generated by the solar panel to the battery for charging or recharging the battery. An electrically operable fluid pump is electrically connected to the battery through a selectively operable relay that controls electrical current from the battery. A fluid inlet of the pump can be connected to a reservoir of a fluid and a fluid outlet of the pump to a pipe. The relay can be selectively controlled to operate the pump, thereby pumping fluid from the reservoir into the pipe. In another aspect, the relay can be selectively preprogrammed with a central processing unit.
    • 提供了一种用于将诸如化学腐蚀抑制剂的流体喷射到管道中的装置和方法。 太阳能电池板由管道位置附近的支撑结构支撑,用于将太阳能转换成电流。 太阳能电池板通过电压调节器电连接到蓄电池,电压调节器将太阳能电池板产生的电流调节到电池以对电池充电或再充电。 电动可操作的流体泵通过选择性操作的继电器电连接到电池,该继电器控制来自电池的电流。 泵的流体入口可以连接到泵的流体和流体出口的储存器到管道。 可以选择性地控制继电器以操作泵,从而将流体从储存器泵送到管道中。 在另一方面,继电器可以选择性地用中央处理单元预编程。
