Karakteristik Pwodwi Pèfòmans nan Gaye nan flanm dife Tester
1. enstriman an tès konsiste de kat eleman prensipal: yon seri radyasyon parantèz plak ak yon seri parantèz echantiyon, ki yo ki konekte ansanm yo fòme estrikti ki nesesè yo ak plak radyasyon, echantiyon bracket ak ignisyon brûler.
2. Plak la radyasyon bay yon sifas ki radyasyon an sou 480 mm X 280 mm, epi li se ekran an metal bay sou devan an radyasyon ogmante radyasyon an.
Se 3. sous Air nan plak radyasyon ki ofri pa balèn, epi li se frekans konvètisè itilize yo kontwole li.
4. Sèvi ak gaz pwopàn koule mas kontwolè kontwole sous gaz, kolabore ak Venturi mixer, melanje ak lè, epi yo bay ki degaje konbisyon sous gaz la pou plak radyasyon.
5. Bay yon plak kalibrasyon ki mouye ak deplase tras nan yon chalè mèt koule glisman kapab detekte si wi ou non règ la radyasyon chalè satisfè kondisyon ki nan estanda la.
6. Dlo-frèt radyasyon chalè Capteur règ, ki te itilize ki mezire radyasyon chalè règ koub la nan plak radyasyon.
7. Portable dlo refwadisman sikile aparèy ka wete chalè a sifas nan mèt koule chalè.
8. tib brûler a seramik ka dirèkteman aji sou sifas la nan echantiyon an tès yo boule nan dife louvri.
9. rotor debimètr ka bay gaz ki degaje konbisyon melanje pou seramik tib brûler.
10. Mass koule kontwolè ka byen fasil mezire chalè a nan metàn pa mezire règ la chalè kritik.
11. Dapre imo estanda tès, aparèy tèrmokapteur yo kapab bay ki mezire pousantaj lage chalè ak lòt paramèt ki gen rapò.
12. brûler a metàn kalibrasyon ak metàn mas kontwolè koule ka bay 1KW ak 3kw tanperati flanm dife.
13. Pandan egzamen-an, kamera a ka obsève, epi sove eta a mezi nan pwogram nan.
14. Ekipe ak yon glas obsèvasyon ang-reglabl, ka to a flanm dife gaye dwe obsève nan glas vè ak echantiyon rato pandan tès la, e yo ka dwe anrejistre otomatikman pa chanje pye.
15. Odinatè ak lojisyèl tès estanda yo te itilize yo kontwole pwosesis la egzamen an.
Product Feature of Gaye nan flanm dife tèsteur
The apparatus consists of a radiant panel having dimensions of 280 x 483 mm, mounted vertically, and making an angle of 15° with the specimen.
The orientation of the panel results in an incident radiant flux that decreases from 50 kW/m² at one end to approximately 1 kW/m² at the other end of the specimen.
The sample is ignited by a non-impinging, gas/air pilot flame.
Viewing rakes placed at a 50-mm spacing along the specimen.
Heat Flux Meter - for setting the irradiance level at the surface of the specimens, the range from 0-50KW/m2.
Portable water cooling system without need for waterworks and plumbing when using the Heat Flux meter.
The radiant burner system is fully automatic, with spark ignition and safety interlocks.
MFC (Mass Flow Controller) to easily measure the heat amount of methane gas in measuring critical heat flux.
Camcorder to observe and save test conditions in a program during tests.
To meet the IMO specification a stack is fitted complete with thermopile for estimating heat release rate.
Records the spread rate of flame after this records ignition and extinguishment time of flame for each distance of specimens. And the other test results is Heat for ignition (MJ/㎡), Heat for sustained burning (MJ/㎡), Critical flux at extinguishment (kW/㎡), Average heat for sustained burning (MJ/㎡), Total heat release (kW),Peak heat release rate (kW) .
How is flame spread measured?
Flame spread rating is calculated by the distance a flame travels across a material, divided by the amount of time it takes to travel that distance. Testing for flame spread rating involves burning materials under controlled conditions and measuring the speed and extent of flame spread.
What is spread of flame test?
Flame spread tests aim at measuring the tendency of a flame to propagate over a substrate and directly correlate to surface flame propagation in a real fire scenario.
