    摘要： Embodiments of the invention provide a fire-extinguishing system for injecting foamant into a stream of water. The system can include a flow meter determining a flow rate of the stream of water and a foam pump having an inlet coupled to a supply of foamant and an outlet coupled to the stream of water. The system includes a servo motor driving the foam pump. The servo motor includes a sensor used to determine a rotor shaft speed and/or a rotor shaft torque. A controller can control an operating speed of the servo motor using closed-loop control depending on the flow rate and the rotor shaft speed and/or the rotor shaft torque.

    摘要： Embodiments of the invention provide a redundant stationary fire fighting system and method for use in a structure coupled to a water supply and a main water pump(s) that generates a water stream. The system includes one or more water flow meters to measure the water stream and generate a water flow signal. The system includes a primary foam proportioning system and a redundant secondary foam proportioning system, each including a foam pump, a motor, a foam flow meter, and a controller. The controller is configured to automatically operate the foam pump based on the water flow signal in order to inject liquid foam concentrate directly into the water stream. The redundant secondary foam proportioning system can be automatically started in case of component failure in the primary foam proportioning system.

    摘要： A compact, stand-alone fire-extinguishing system for use with a water source is disclosed. The fire-extinguishing system can include an engine, a pump, a foam tank, a flow meter, and a foamant adjustment valve. The flow meter can be a variable area flow meter and indicate an instantaneous concentration of a water-foamant solution. The foamant adjustment valve can be a needle valve. A head injector can be coupled to the pump. The head injector provides foamant to be mixed with water inside the pump to create a water-foamant solution. The fire-extinguishing system may also include an inlet mixing valve assembly and an unloader valve to recirculate the water-foamant solution.

    摘要： Embodiments of the invention provide a fire-fighting system including a low-pressure system and an ultra-high pressure system (UHPS). The fire-fighting system can also include a foam proportioning system, which can inject a foamant into the low-pressure system and/or the UHPS. The low-pressure system and the UHPS can be simultaneously operated. Some embodiments of the fire-fighting system can be installed on aircraft rescue fire fighting (ARFF) vehicles.
