固定液上喷射泡沫灭火系统：
Fixed liquid spray foam extinguishing system:
是将泡沫喷射施放燃烧液体表面，形成泡沫层的灭火系统。主要适用于独立油库的地上固定顶立式贮罐、地上浮顶油罐；化工企业的燃烧罐；油罐区防火堤内等火灾危险性较大的场所。该系统由固定的泡沫混合液泵、单向阀、闸阀、泡沫比例混合器、泡沫液贮罐、泡沫混合液管线、泡沫产生器以及水源和动力源组成。
It is a fire extinguishing system that sprays foam onto the surface of combustion liquid to form a foam layer. Mainly suitable for above ground fixed roof vertical storage tanks and above ground floating roof oil tanks in independent oil depots; Combustion tanks for chemical enterprises; Places with high fire hazards such as fire dikes in oil tank areas. The system is composed of fixed foam mixture pump, one-way valve, gate valve, foam proportioner, foam concentrate tank, foam mixture pipeline, foam generator, water source and power source.
Fixed liquid injection foam fire extinguishing system of Chuanxiao:
是将泡沫从液面下喷射入罐内，泡沫通过液体上升液体表面，扩散形成泡沫层覆盖燃烧液体表面，窒息灭火的系统。由固定的泡沫混合液泵、负压空气泡沫比例混合器、高背压泡沫产生器、管线、闸阀以及水源和动力源组成。主要适用于独立油库的地上固定顶立式贮罐，不适用于浮顶油罐、水溶性甲、乙、丙类液体贮罐和粘度大的原油和重油。
It is a system that sprays foam from below the liquid surface into the tank, and foam rises to the liquid surface through the liquid, and spreads to form a foam layer covering the surface of the burning liquid, suffocating and extinguishing the fire. It is composed of fixed foam mixture pump, negative pressure air foam proportioner, high back pressure foam generator, pipeline, gate valve, water source and power source. Mainly suitable for above ground fixed roof vertical storage tanks in independent oil depots, not suitable for floating roof oil tanks, water-soluble Class A, B, and C liquid storage tanks, and high viscosity crude oil and heavy oil.
半固定式液上喷射泡沫灭火系统：
Semi fixed liquid spraying foam extinguishing system:
是由水源或消火栓、泡沫消防车、消防水带、泡沫混合液管线和空气泡沫产生器等组成的泡沫灭火系统。主要适用于有较强机动消防力量的企业的附属油库、化工装置区等危险场所。不宜用于地形不平坦的地方。
It is a foam extinguishing system composed of water source or fire hydrant, foam fire truck, fire hose, foam mixture pipeline and air foam generator. Mainly suitable for hazardous locations such as affiliated oil depots and chemical plant areas of enterprises with strong mobile firefighting capabilities. Not suitable for use in areas with uneven terrain.
半固定液下喷射泡沫灭火系统：
Semi fixed submerged spray foam extinguishing system:
除泡沫产生器必须使用高背压泡沫产生器，并在高背压泡沫产生器和贮罐之间设置止回阀和闸阀外，其系统组成、工作原理和半固定液上喷射泡沫灭火系统基本相同。主要适用于地形平坦的、有较强机动消防力量企业的地上固定顶立式油罐，不适用于炼油和化工厂加工装置以及化工产品贮罐。
Except that the foam generator must use a high back pressure foam generator, and a check valve and gate valve are set between the high back pressure foam generator and the storage tank, the system composition and working principle are basically the same as the semi fixed liquid foam extinguishing system. Mainly suitable for aboveground fixed top vertical oil tanks in flat terrain and enterprises with strong mobile firefighting capabilities, not suitable for processing units in refineries and chemical plants, as well as chemical product storage tanks.
移动式液上喷射泡沫灭火系统：
Mobile liquid spraying foam extinguishing system:
是由水源、泡沫消防车、水带、泡沫管钩、泡沫枪或泡沫管架等设备组成和泡沫灭火系统。
It is composed of water source, foam fire truck, hose, foam pipe hook, foam gun or foam pipe rack and other equipment and foam fire extinguishing system.
泡沫喷淋系统：
Foam spray system:
用喷头喷洒泡沫的固定灭火系统称为泡沫喷淋系统。适用于保护甲、乙、丙类液体可能泄露和机动消防设施不足的场所。由固定泡沫混合液泵、泡沫比例混合器、泡沫液贮罐、闸阀、过滤装置、泡沫混合液管线、吸气型（或非吸气型）泡沫喷头、水源、动力源、火灾自动报警装置和联动控制设备组成。
The fixed fire extinguishing system that sprays foam with sprinklers is called foam spraying system. Suitable for protecting places where Class A, B, and C liquids may leak and there are insufficient mobile firefighting facilities. It is composed of fixed foam mixture pump, foam proportioner, foam liquid storage tank, gate valve, filtering device, foam mixture pipeline, aspirating (or non aspirating) foam nozzle, water source, power source, automatic fire alarm device and linkage control equipment.
