固定液上噴射泡沫滅火系統(tǒng)：
Fixed liquid spray foam extinguishing system:
是將泡沫噴射施放燃燒液體表面，形成泡沫層的滅火系統(tǒng)。主要適用于獨(dú)立油庫的地上固定頂立式貯罐、地上浮頂油罐；化工企業(yè)的燃燒罐；油罐區(qū)防火堤內(nèi)等火災(zāi)危險(xiǎn)性較大的場所。該系統(tǒng)由固定的泡沫混合液泵、單向閥、閘閥、泡沫比例混合器、泡沫液貯罐、泡沫混合液管線、泡沫產(chǎn)生器以及水源和動(dòng)力源組成。
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:
是將泡沫從液面下噴射入罐內(nèi)，泡沫通過液體上升液體表面，擴(kuò)散形成泡沫層覆蓋燃燒液體表面，窒息滅火的系統(tǒng)。由固定的泡沫混合液泵、負(fù)壓空氣泡沫比例混合器、高背壓泡沫產(chǎn)生器、管線、閘閥以及水源和動(dòng)力源組成。主要適用于獨(dú)立油庫的地上固定頂立式貯罐，不適用于浮頂油罐、水溶性甲、乙、丙類液體貯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.
半固定式液上噴射泡沫滅火系統(tǒng)：
Semi fixed liquid spraying foam extinguishing system:
是由水源或消火栓、泡沫消防車、消防水帶、泡沫混合液管線和空氣泡沫產(chǎn)生器等組成的泡沫滅火系統(tǒng)。主要適用于有較強(qiáng)機(jī)動(dòng)消防力量的企業(yè)的附屬油庫、化工裝置區(qū)等危險(xiǎn)場所。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.
半固定液下噴射泡沫滅火系統(tǒng)：
Semi fixed submerged spray foam extinguishing system:
除泡沫產(chǎn)生器必須使用高背壓泡沫產(chǎn)生器，并在高背壓泡沫產(chǎn)生器和貯罐之間設(shè)置止回閥和閘閥外，其系統(tǒng)組成、工作原理和半固定液上噴射泡沫滅火系統(tǒng)基本相同。主要適用于地形平坦的、有較強(qiáng)機(jī)動(dòng)消防力量企業(yè)的地上固定頂立式油罐，不適用于煉油和化工廠加工裝置以及化工產(chǎn)品貯罐。
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.
移動(dòng)式液上噴射泡沫滅火系統(tǒng)：
Mobile liquid spraying foam extinguishing system:
是由水源、泡沫消防車、水帶、泡沫管鉤、泡沫槍或泡沫管架等設(shè)備組成和泡沫滅火系統(tǒng)。
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.
泡沫噴淋系統(tǒng)：
Foam spray system:
用噴頭噴灑泡沫的固定滅火系統(tǒng)稱為泡沫噴淋系統(tǒng)。適用于保護(hù)甲、乙、丙類液體可能泄露和機(jī)動(dòng)消防設(shè)施不足的場所。由固定泡沫混合液泵、泡沫比例混合器、泡沫液貯罐、閘閥、過濾裝置、泡沫混合液管線、吸氣型（或非吸氣型）泡沫噴頭、水源、動(dòng)力源、火災(zāi)自動(dòng)報(bào)警裝置和聯(lián)動(dòng)控制設(shè)備組成。
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.
