悬挂式干粉灭火装置是日常生活中不常见的灭火器类型，但在消防方面具有独特的优势。下面川消小编来讲讲悬挂式干粉灭火装置的五大适用范围。

Suspended dry powder fire extinguisher is an uncommon type of extinguisher in daily life, but it has unique advantages in fire protection. Next, let's talk about the five applicable ranges of the suspended dry powder fire extinguishing device.

悬挂式干粉灭火装置具有灭火效率高、腐蚀性小、绝缘性能好、无管道、无线路、结构轻、小、合理等优点。特别适用于油库、油漆仓库、配电室、干燥室等经常无人工作的场所，是室内有效的自动灭火设备之一。

The suspended dry powder fire extinguishing device has the advantages of high fire extinguishing efficiency, low corrosion, good insulation, no pipeline, no line, light, small and reasonable structure, etc. It is especially suitable for oil depots, paint warehouses, power distribution rooms, drying rooms and other places where no one often works. It is one of the effective indoor automatic fire extinguishing equipment.

A类火灾：固体有机物燃烧火灾。这些物质燃烧后，通常会形成木材、纸张、棉织物等热余烬。

Class A fire: solid organic burning fire. When these substances are burned, they usually form thermal embers such as wood, paper and cotton fabrics.

B类火灾：液体或可熔固体燃烧的火灾。如汽油、柴油、煤油、沥青、醇、酯、醚、酮、油等火灾。

Class B fire: fire caused by burning of liquid or fusible solid. Such as gasoline, diesel, kerosene, asphalt, alcohol, ester, ether, ketone, oil and other fires.

C类火灾：燃气火灾。如燃气、液化石油气、天然气等可燃气体的火灾。

Class C fire: gas fire. Such as gas, liquefied petroleum gas, natural gas and other combustible gas fires.

D类火灾：轻金属燃烧火灾。如钾、钠、镁、铅、海绵钛等轻金属火灾。

Class D fire: light metal burning fire. Such as potassium, sodium, magnesium, lead, sponge titanium and other light metal fires.

E类火灾：电气火灾。

Class E fire: electrical fire.

悬挂式干粉灭火装置由罐体、感温玻璃喷嘴、压力表、吊环等部件组成，配备ABC干粉灭火剂，适量的驱动气体氮气，在喷口部位装有感温玻璃喷嘴，当发生火灾时，温度升高到设定的动作温度，内部灭火剂分解、汽化和膨胀。

The suspended dry powder fire extinguishing device is composed of tank body, temperature sensing glass nozzle, pressure gauge, lifting ring and other components, equipped with ABC dry powder extinguishing agent, appropriate driving gas nitrogen, and temperature sensing glass nozzle at the nozzle. In case of fire, the temperature rises to the set action temperature, and the internal extinguishing agent decomposes, vaporizes and expands.

当膨胀力超过玻璃管的耐压强度时，玻璃管爆裂，汽化产生的二氧化碳和氨气，二氧化碳直接夺取空气中的氧气，氮气可有效降低空气温度，达到灭火的目的。更多相关使用问题就来我们网站http://www.cx-fire.com咨询吧！

When the expansion force exceeds the compressive strength of the glass tube, the glass tube will burst, and the carbon dioxide and ammonia produced by vaporization will directly capture the oxygen in the air. Nitrogen can effectively reduce the air temperature to extinguish the fire. More related use questions come to our website http://www.cx-fire.com Consult!
