柜式七氟丙烷氣體滅火裝置中主要常用空瓶部件40、70、90、120、150升重量，分別為44、59、71、87、112Kg左右。有管網(wǎng)七氟丙烷氣體滅火系統(tǒng)中主要常用空瓶部件70、90、120、150升重量，分別為68、81、100、120Kg左右。提供上述七氟丙烷滅火劑空瓶部件重量，有利于工程商、用戶、監(jiān)理、檢測(cè)驗(yàn)收單位監(jiān)督檢測(cè)稱重時(shí)，參考使用。

The often-used 40,70,90,120 and 150-liter empty cylinders in cabinet HFC-227ea gas extinguishing devices weigh around 44,59,71,87 and 112 kilograms respectively.The often-used 70,90,120 and 150-liter empty cylinders in HFC-227ea gas extinguishing equipment with pipe network weigh around 68,81,100,and 120 kilograms respectively.We provide the weights of the empty HFC-227ea fire extinguishing agent cylinders for the purpose of providing reference for engineering service providers,users,supervisors and inspection and accepting units in their weighing and checking.

措施如下：發(fā)貨前到廠家或項(xiàng)目安裝現(xiàn)場(chǎng)瓶組間，隨機(jī)抽檢1～3瓶滅火劑瓶組，檢測(cè)總重量；檢測(cè)該瓶組是否處于密封性完好，無泄漏現(xiàn)象；若稱重滅火劑瓶組總重量不夠，說明氣體廠家少充裝或經(jīng)營(yíng)者（工程商）修改了產(chǎn)品銘牌上標(biāo)稱重量，并不是氣體滅火劑泄漏了。分別列出隨機(jī)抽檢滅火劑瓶組，空瓶部件重量（廠家提供和參考本文章中重量）、滅火藥劑重量（對(duì)照設(shè)計(jì)院設(shè)計(jì)圖紙重量）、驅(qū)動(dòng)氣體氮?dú)庵亓?，?jì)算出該瓶組七氟丙烷滅火藥劑實(shí)際充裝重量。

Measures to take:before the manufacturer delivers the products,go to the location of the manufacturer,or to the cylinder group room at project’s installation site and make random sampling of one to three fire extinguishing agent cylinder groups and check their total weights;check if the cylinder groups are stilled perfectly sealed with no sign of any leaking;if the total weight of a fire extinguishing agent cylinder group is below standard,it means the gas manufacturer has failed to fill enough gas into the cylinder,or the dealer(or engineering service provider)has changed the weight provided on the product plate,and not because there is leakage of the agent.Based on the result of the random sampling of fire extinguishing agent cylinder groups,list the weights of the empty cylinders(vs the weights provided by the manufacturer and the weight provided above),the weights of fire extinguishing agents(vs the weights provided on the drawings made by the design institute,the weights of propellant nitrogen gas,calculate based on the above information and find out the actual weight of HFC-227ea fire extinguishing agent fill into the cylinder group.

例：抽檢有管網(wǎng)七氟丙烷氣體滅火系統(tǒng)150升瓶組一瓶，計(jì)算該瓶組七氟丙烷滅火藥劑實(shí)際充裝重量。

For example:sample-checking one of the cylinders of an 150-liter-cylinder group of a HFC-227ea gas extinguishing system with pipe network to find out the actual weight of HFC-227ea filled into this cylinder group.

檢測(cè)與計(jì)算如下：

①檢測(cè)150升瓶組密封性，無泄漏；

②稱150升瓶組重量,若為W=256.6Kg；

③檢查該瓶組銘牌標(biāo)稱重量和設(shè)計(jì)院設(shè)計(jì)重量是否一致；

④檢查該瓶組銘牌標(biāo)稱重量表示七氟丙烷藥劑充裝重量：122Kg，瓶組總重量：256.5Kg；

⑤計(jì)算七氟丙烷滅火藥劑充裝重量首先依據(jù)廠家提供150升空瓶部件重量或參考本文章中150升空瓶部件重量W1=128.6kg；藥劑W2與氮?dú)釽3重量為（256.6-128.6=128Kg，則氮?dú)庵亓繛閃3=256.6-128.6-122=6Kg，氮?dú)庵亓空计叻闇缁饎┲亓康模?/122×100%）=4.9%，該氮?dú)獗壤媳疚囊?。七氟丙烷滅火藥劑?shí)際充裝重為122Kg，符合規(guī)定要求。

The following are the checks and calculations:

①Check the sealing property of the 150-liter-cylinder group and make sure there is no leaking;

②Weigh the 150-liter-cylinder group,and if W=256.6Kg,

③Check if the weight provided on the product plate of the cylinder group is the same as the one designated by the design institute;

④Check the plate on the cylinder group to see if the weight of HFC-227ea filled into the cylinder is 122kg and the total weight of the cylinder group is 256.5kg;

⑤The calculation of the weight of the HFC-227ea agent filled in the cylinder should be based on the weight of the 150-liter empty cylinder provided by the manufacturer,or in reference to the weight of the 150-liter empty cylinder provided above:W1=128.6kg;the weight of the agent W2=256.6-128.6=128kg,while the weight of nitrogen gas W3=256.6-128.6-122=6kg,and nitrogen gas account for(6/122×100%=)4.9%of the weight of HFC-227ea,which conforms to the required rate provided above.The actual weight of HFC-227ea fire extinguishing agent filled in the cylinder is 122 kg,conforming to the required standard.
