貯壓懸掛式超細(xì)干粉滅火裝置和非貯壓懸掛式超細(xì)干粉滅火裝置之間的區(qū)別不是一個(gè)“非”字的差別，下面我們就詳細(xì)看看
川消小編對(duì)兩類型的超細(xì)干粉滅火裝置此區(qū)別的描述：
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:
滅火劑噴放性能
Fire extinguishing agent spray performance
貯壓懸掛式超細(xì)干粉滅火裝置噴放時(shí)能維持較長(zhǎng)的噴射時(shí)間（≥5S）。滅火劑噴射狀態(tài)均勻，快速擴(kuò)散，霧化效果好。當(dāng)全淹沒(méi)滅火時(shí)，使防護(hù)區(qū)每個(gè)角落快速達(dá)到設(shè)計(jì)滅火濃度，迅速滅火；當(dāng)局部滅火時(shí)，滅火劑在連續(xù)數(shù)秒不間斷對(duì)保護(hù)對(duì)象滅火和降溫，使保護(hù)對(duì)象浸漬在高滅火劑濃度中，使保護(hù)對(duì)象火災(zāi)難以復(fù)燃。氣體和超細(xì)干粉滅火劑大特點(diǎn)是滅火速度快；缺點(diǎn)是保護(hù)對(duì)象浸漬時(shí)間短，易復(fù)燃。如日常中操作手提式滅火器，噴射秒鐘時(shí)很難將火災(zāi)撲滅，一般均應(yīng)連續(xù)噴射3～8秒滅火劑后，方能將火災(zāi)后撲滅。噴射的滅火劑在惰性氣體的帶動(dòng)下與氣體均勻混合再以氣體方式釋放到空間。噴放時(shí)不產(chǎn)生熱量，與裝置儲(chǔ)存環(huán)境溫度一致。噴放聲音很小，滅火裝置屬無(wú)聲啟動(dòng)，無(wú)噪聲污染。
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.
非貯壓懸掛式超細(xì)干粉滅火裝置噴放時(shí)為瞬間噴射（一般≤1S，固氣轉(zhuǎn)換型稍長(zhǎng)點(diǎn)，但不穩(wěn)定），非貯壓懸掛式干粉滅火裝置，又稱脈沖式懸掛式干粉滅火裝置。滅火劑噴放狀態(tài)為定向噴射，定向沖擊，霧化效果差。滅火劑噴射具有方向性，如果噴射到空曠的防護(hù)區(qū)內(nèi)或離保護(hù)物較遠(yuǎn)的情況下，滅火劑受到緩沖不能形成粉霧而影響滅火效果，甚其中有部分干粉成自由落體狀掉落到地面而未參與滅火。噴放時(shí)氣體發(fā)生劑（火藥）燃燒產(chǎn)生高溫高熱，局部高可達(dá)200℃以上。且噴放聲音大，有噪聲污染，氣體發(fā)生劑爆燃后產(chǎn)生的聲響很大，特別是脈沖式或超音速式類型的滅火裝置，瞬間爆破的聲響巨大。
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.
滅火效果
Fire extinguishing effect
貯壓懸掛式超細(xì)干粉滅火裝置滅火效果穩(wěn)定。滅火劑在貯瓶?jī)?nèi)儲(chǔ)存的惰性氣體的作用下，攜帶足夠的動(dòng)能，均勻的噴射、霧化到防護(hù)區(qū)內(nèi)，可繞過(guò)障礙物的縫隙擴(kuò)散到任意位置，實(shí)施連續(xù)不斷的在一定設(shè)計(jì)滅火濃度懸掛式干粉滅火裝置為c≥0.13kg/m3下滅火，將保護(hù)對(duì)象數(shù)秒內(nèi)持續(xù)浸漬在這一設(shè)計(jì)濃度中，滅火效果非常好。
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.
非貯壓懸掛式超細(xì)干粉滅火裝置滅火效果不穩(wěn)定。滅火劑依靠氣體發(fā)生劑（火藥）爆燃產(chǎn)生的沖擊力，定向噴灑在防護(hù)區(qū)內(nèi)，滅火劑噴出后由于缺乏后續(xù)的推力，不能很好的擴(kuò)散到各個(gè)角落，部分顆粒甚會(huì)直接掉落下來(lái)，難以連續(xù)在一定設(shè)計(jì)滅火濃度下，數(shù)秒內(nèi)滅火。由于非貯壓懸掛式超細(xì)干粉滅火裝置有效噴射時(shí)間小于1秒，滅火效果很不穩(wěn)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.
密封性和耐腐蝕性能
Sealing and corrosion resistance
貯壓懸掛式超細(xì)干粉滅火裝置按壓力容器的標(biāo)準(zhǔn)制造（承壓能力大于等于2.1MPa），滅火劑被密封在一種隋性氣體內(nèi)，保證空氣無(wú)法進(jìn)入以確保滅火劑始終處于干燥的狀態(tài)，具有良好的密封性能。容器設(shè)計(jì)使用年限20年，具有很好的抗腐蝕性能。
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.
非貯壓懸掛式超細(xì)干粉滅火裝置以鋁膜壓邊封口，密封性一般。如果安裝到潮濕的地下室等場(chǎng)所，潮濕空氣進(jìn)入滅火裝置內(nèi)會(huì)導(dǎo)致滅火劑受潮而失效。如果滅火裝置安裝在有腐蝕性氣體的環(huán)境中，封口鋁膜很薄易氧化，很容易受到腐蝕而破損。
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.
