DUK apie dujinę gaisro gesinimo sistemą FM200, pagrįstą gesinimo medžiaga HFC-227ea

Mes išvardijame mūsų dujines gaisro gesinimo sistemas, kurios paprastai išsiskiria gesinamosios medžiagos pavadinimu, Dažni yra heptafluorpropanas, IG541, IG55, IG01, NOVEC1230 ir anglies dioksidas; kilus gaisrui, yra daug nepagrįstų veiksnių, ir inžinieriai turi išsamiai išanalizuoti visus veiksnius, kad pasirinktų taikomą dujų slopinimo sistemos įrengimo schemą, Toliau pateikiami keli dažnai užduodami klausimai apie dujų gaisro gesinimo sistemas, ypač heptafluorpropano sistemos.

KLAUSIMAS 1: KODĖL ŽMONĖS RENKASI HFC-227EA HEPTAFLUORPROPANO DUJŲ GAISRO GESINIMO SISTEMĄ

Per įvairius palyginimus, we can further determine which gas to use by taking the nature of the gas as a necessary factor and then make choice, Through analysis and market research it is found that heptafluoropropane is the most stable gas, which is clean and pollution-free. Therefore, most of the gas fire extinguishing systems in the market are heptafluoropropane.

KLAUSIMAS 2: WHY FM200 FIRE EXTINGUISHING SYSTEM CAN REPLACE HALON SYSTEM

Heptafluoropropane fire extinguishing system is a new type of gas fire extinguishing system. Based on the extensive use of carbon dioxide fire extinguishing system, it has promoted the extensive use of heptafluoropropane and IG541 gas.

Heptafluoropropane fire extinguishing system is a new type of gas fire extinguishing system. Based on the extensive use of carbon dioxide fire extinguishing system, it has promoted the extensive use of heptafluoropropane and IG541 inert gas fire extinguishing system, Today, heptafluoropropane have become the world’s major halothane 1301 gas alternative products.

The heptafluoropropane fire extinguishing sysem can replace HALON1301 mainly because of the following two reasons:

The heptafluoropropane fire extinguishing system can replace HALON1301 mainly because of the following three reasons:

• The fire extinguishing efficiency of heptafluoropropane is 1.6 times that of 1301.
• The pipes of heptafluoropropane fire extinguishing system and HALON1301 can be shared and common.
• FM200 system is clean without pollution to the environment, and will not damage the amosphere.

KLAUSIMAS 3: WHICH TYPE OF FIRES ARE SUITABLE FOR GAS FIRE EXTINGUISHING SYSTEM(Heptafluoropropane)?

The gas fire extinguishing system is applicable to the following fires:

• Electrical fires, E klasė.
• Solid surface fire, A klasė.
• Liquid Fire, B klasė.
• Gas fire which can cut off the gas source before extinguishing, C klasė.

The gas fire extinguishing system (heptafluoropropane) is not suitable for fighting the following fires:

• Fire caused by nitrocellulose, sodium nitrate and other oxidants or chemicals containing oxidants.
• Fire of potassium, magnesium, sodium, titanium, zirconium, uranium and other active metals.
• Potassium hydride, sodium hydride and other metal hydride fires.
• Fire caused by self decomposing chemical substances such as hydrogen peroxide and hydrazine.
• Deep fire of combustible solid materials.

KLAUSIMAS 4: WHAT TO DO WHEN HEPTAFLUOROPROPANE FIRE EXTINGUISHING SYSTEM IS USED UP?

The engineeering companies often ask us a question, tai yra: when the heptafluoropropane fire extinguishing system is used up, how do we deal with it? Šiuo klausimu, our answer as below:

After the heptafluoropropane fire extinguishing system is sprayed, the remaining fire extinguishing agent bottle groups can still be used after being filled, Kadangi šiuo metu apsaugos zonoje nėra gaisro gesinimo sistemos, būtina kuo greičiau susisiekti su gamintoju, kad būtų išvengta didesnių nuostolių.

Heptafluorpropano agentas turi būti užpildytas specialiu prietaisu, Paprastai jo butelių grupę reikia išardyti ir grąžinti į originalią gamyklą. Pažymėtina, kad gaisro gesinimo butelių grupės išmontavimą ir surinkimą turėtų atlikti priešgaisrinės apsaugos pramonėje specializuotas personalas.. išleidus heptafluorpropano gaisro gesinimo sistemą, paprastai būtina kuo greičiau atkurti gaisro gesinimo sistemą, taigi gamintojas privalo greitai reaguoti.

KLAUSIMAS 5: KAIP DAŽNAI REIKIA UŽPILDYTI HEPTAFLUORPROPANO GAISRO GESINIMO SISTEMĄ?

Visų pirma, jei nuotėkis, pressure corrosion and other conditions are found, it is necessary to detect and inflate the equipment as soon as possible to ensure the normal operation of the fire extinguishing system, otherwise, kilus gaisrui, the loss is incalculable.

Antra, the steel cylinder (bottle) of the heptafluoropropane fire extinguishing system should be tested once every three years, and the corresponding test report should be issued, because of the uncertainty of the use environment; it is easy to lead to corrosion of parts and lead to leakage of the system. If the pressure is abnormal during the three years, leakage and other phenomena occur, it is necessary to timely test, repair, repressurize and inflate; If there is no specific time limit, the gas should be tested as long as there is leakage.

According to the regulations of cylinder safety supervision regulations：

• Gas cylinders containing nitrogen, sulfur hexafluoride, inert gas and non corrosive high-purity gas with purity not less than 99.999% shall be inspected once every 5 Metų.
• Gas cylinders, submersible gas cylinders and gas cylinders that are often in contact with seawater containing gases that can cause corrosion to the cylinder materials shall be inspected once every two years.
• Gas cylinders containing other gases shall be inspected once every three years.

KLAUSIMAS 9: DOES THE PROTECTION AREA WHERE HEPTAFLUOROPROPANE IS LOCATED NEED PRESSURE RELIEF AFTER IT IS SPRAYED?

According to the fire protection design code, after heptafluoropropane is sprayed, its protection area needs to be depressurized, it need a Pressure Relief Damper to be installed on the external wall.

KLAUSIMAS 10: WHAT ARE THE CHARACTERISTICS OF HEPTAFLUOROPROPANE FIRE EXTINGUISHING SYSTEMS MADE IN CHINA?

Our biggest feature is to produce cabinet type HFC-227ea fire extinguishing device, which does not need any pipe network and easy to install in the defense area, please check our MONTAVIMO VADOVAS for a overview.

KLAUSIMAS 11: COMPARED WITH NOVEC 1230 SYSTEMS, WHICH IS BETTER?

FM-200 system at present is better, because at present the NOVEC 1230 system or FK5112 system is not stable; be to, FM200 has been verified by the market and recognized by customers.
