贮压悬挂式超细干粉灭火装置和非贮压悬挂式超细干粉灭火装置之间的区别不是一个“非”字的差别，下面我们就详细看看
川消小编对两类型的超细干粉灭火装置此区别的描述：
The difference between the storage pressure suspended ultra-fine dry powder fire extinguishing device and the non storage pressure suspended ultra-fine dry powder fire extinguishing device is not just a "non" word difference. Below, we will take a detailed description of the difference between the two types of ultra-fine dry powder fire extinguishing devices by Sichuan Xiaobian:
灭火剂喷放性能
Fire extinguishing agent spray performance
贮压悬挂式超细干粉灭火装置喷放时能维持较长的喷射时间（≥5S）。灭火剂喷射状态均匀，快速扩散，雾化效果好。当全淹没灭火时，使防护区每个角落快速达到设计灭火浓度，迅速灭火；当局部灭火时，灭火剂在连续数秒不间断对保护对象灭火和降温，使保护对象浸渍在高灭火剂浓度中，使保护对象火灾难以复燃。气体和超细干粉灭火剂大特点是灭火速度快；缺点是保护对象浸渍时间短，易复燃。如日常中操作手提式灭火器，喷射秒钟时很难将火灾扑灭，一般均应连续喷射3～8秒灭火剂后，方能将火灾后扑灭。喷射的灭火剂在惰性气体的带动下与气体均匀混合再以气体方式释放到空间。喷放时不产生热量，与装置储存环境温度一致。喷放声音很小，灭火装置属无声启动，无噪声污染。
The pressure storage suspension type ultrafine dry powder fire extinguishing device can maintain a longer spraying time (≥ 5S) during spraying. The spraying state of the fire extinguishing agent is uniform, rapid diffusion, and good atomization effect. When completely submerged for fire extinguishing, quickly reach the designed fire extinguishing concentration in every corner of the protective zone, and quickly extinguish the fire; When a local fire is extinguished, the extinguishing agent continuously extinguishes and cools the protected object for several seconds, immersing the protected object in a high concentration of extinguishing agent, making it difficult for the protected object to ignite again. The main characteristic of gas and ultrafine dry powder fire extinguishing agents is their fast extinguishing speed; The disadvantage is that the immersion time of the protected object is short and easy to reignite. If you operate a portable fire extinguisher in daily life, it is difficult to extinguish the fire in the first second of spraying. Generally, you should continuously spray the extinguishing agent for 3-8 seconds before extinguishing the fire afterwards. The sprayed extinguishing agent is evenly mixed with inert gas and then released into space in a gaseous manner. During spraying, no heat is generated, which is consistent with the temperature of the storage environment of the device. The spraying sound is very low, and the fire extinguishing device is silent to start, without noise pollution.
非贮压悬挂式超细干粉灭火装置喷放时为瞬间喷射（一般≤1S，固气转换型稍长点，但不稳定），非贮压悬挂式干粉灭火装置，又称脉冲式悬挂式干粉灭火装置。灭火剂喷放状态为定向喷射，定向冲击，雾化效果差。灭火剂喷射具有方向性，如果喷射到空旷的防护区内或离保护物较远的情况下，灭火剂受到缓冲不能形成粉雾而影响灭火效果，甚其中有部分干粉成自由落体状掉落到地面而未参与灭火。喷放时气体发生剂（火药）燃烧产生高温高热，局部高可达200℃以上。且喷放声音大，有噪声污染，气体发生剂爆燃后产生的声响很大，特别是脉冲式或超音速式类型的灭火装置，瞬间爆破的声响巨大。
The non pressure storage suspension type ultrafine dry powder fire extinguishing device is an instantaneous spray (generally ≤ 1S, the solid-gas conversion type is slightly longer, but unstable) when sprayed. The non pressure storage suspension type dry powder fire extinguishing device, also known as the pulse type suspension type dry powder fire extinguishing device. The spraying state of the fire extinguishing agent is directional spraying, with directional impact and poor atomization effect. The spraying of extinguishing agent is directional. If the extinguishing agent is sprayed into an open protection area or far away from the protection object, it can not form a powder mist due to buffering, which affects the fire extinguishing effect, and even some of the dry powder falls to the ground in Free fall form without participating in the fire extinguishing. During spraying, the combustion of gas generating agent (gunpowder) generates high temperature and heat, with local temperatures reaching over 200 ℃. Moreover, the spraying sound is loud and there is noise pollution. The sound generated after the detonation of gas generating agents is very loud, especially for pulse or supersonic type fire extinguishing devices, the instantaneous explosion sound is huge.
灭火效果
Fire extinguishing effect
贮压悬挂式超细干粉灭火装置灭火效果稳定。灭火剂在贮瓶内储存的惰性气体的作用下，携带足够的动能，均匀的喷射、雾化到防护区内，可绕过障碍物的缝隙扩散到任意位置，实施连续不断的在一定设计灭火浓度悬挂式干粉灭火装置为c≥0.13kg/m3下灭火，将保护对象数秒内持续浸渍在这一设计浓度中，灭火效果非常好。
The pressure storage suspension type ultrafine dry powder fire extinguishing device has stable fire extinguishing effect. Under the action of the inert gas stored in the storage bottle, the fire extinguishing agent carries sufficient kinetic energy and evenly sprays and atomizes into the protective zone. It can bypass the gaps of obstacles and diffuse to any position, implementing a continuous hanging dry powder fire extinguishing device at a certain design concentration of c ≥ 0.13kg/m3. The protected object is continuously immersed in this design concentration for several seconds, and the fire extinguishing effect is very good.
非贮压悬挂式超细干粉灭火装置灭火效果不稳定。灭火剂依靠气体发生剂（火药）爆燃产生的冲击力，定向喷洒在防护区内，灭火剂喷出后由于缺乏后续的推力，不能很好的扩散到各个角落，部分颗粒甚会直接掉落下来，难以连续在一定设计灭火浓度下，数秒内灭火。由于非贮压悬挂式超细干粉灭火装置有效喷射时间小于1秒，灭火效果很不稳定。
The non pressure storage suspended ultrafine dry powder fire extinguishing device has unstable fire extinguishing effect. Extinguishing agents rely on the impact force generated by the detonation of gas generating agents (gunpowder) and are sprayed in a targeted manner within the protective zone. After the extinguishing agent is sprayed, due to the lack of subsequent thrust, it cannot spread well to various corners, and some particles may even fall directly, making it difficult to continuously extinguish the fire within a few seconds at a certain designed extinguishing concentration. Due to the effective spraying time of the non pressure storage suspended ultrafine dry powder fire extinguishing device being less than 1 second, the fire extinguishing effect is very unstable.
密封性和耐腐蚀性能
Sealing and corrosion resistance
贮压悬挂式超细干粉灭火装置按压力容器的标准制造（承压能力大于等于2.1MPa），灭火剂被密封在一种隋性气体内，保证空气无法进入以确保灭火剂始终处于干燥的状态，具有良好的密封性能。容器设计使用年限20年，具有很好的抗腐蚀性能。
The pressure storage suspension type ultrafine dry powder fire extinguishing device is manufactured according to the standard of pressure vessels (with a pressure bearing capacity greater than or equal to 2.1MPa), and the fire extinguishing agent is sealed in a inert gas to ensure that air cannot enter and ensure that the fire extinguishing agent is always in a dry state, with good sealing performance. The designed service life of the container is 20 years and it has excellent corrosion resistance.
非贮压悬挂式超细干粉灭火装置以铝膜压边封口，密封性一般。如果安装到潮湿的地下室等场所，潮湿空气进入灭火装置内会导致灭火剂受潮而失效。如果灭火装置安装在有腐蚀性气体的环境中，封口铝膜很薄易氧化，很容易受到腐蚀而破损。
The non pressure storage suspended ultrafine dry powder fire extinguishing device is sealed with aluminum film edge pressing, and the sealing performance is average. If installed in a damp basement or other location, moist air entering the fire extinguishing device can cause the extinguishing agent to become damp and fail. If the fire extinguishing device is installed in an environment with corrosive gases, the sealing aluminum film is very thin and easy to oxidize, which is easily corroded and damaged.
That's all for the comparison of pressure storage and non pressure storage suspended ultrafine dry powder fire extinguishing devices. We hope it can be helpful to you. For more information, please come to our website http://www.cx-fire.com Consult and learn more!
