Āhuatanga mahinga Hua o Horapa o Flame Tester
Ngā 1. Ko te mea whakamātautau o whā wāhanga matua: he huinga o taiapa pereti radiation me te huinga o taiapa tauira, e kua hono tahi ki te hanga i te hanganga e hiahiatia ana ki te pereti radiation, tauira taiapa me te pātīmata pūwera.
2. E whakarato ana te pereti radiation te mata radiation e pā ana ki 480 mm X 280 mm o, ka whakaratohia te mata whakarewa kei i runga i te mua radiation ki te whakapiki ake i te radiation.
Whakaratohia 3. Air puna o te pereti radiation e pupuhi, ka whakamahia auau converter te ki te whakahaere i te reira.
4. Whakamahia pōwaro pūmana rere papatipu ki te whakahaere i pūtake hau, mahi ki Venturi whakaranu, uru ki te hau, a ka whakarato ngingiha pūtake hau mo pereti radiation.
5. Te whakarato i te pereti whakatika maiengi, me te neke ara o te retireti mita rere wera e taea kitea ranei tutuki te rere radiation wera nga whakaritenga o te paerewa.
6. Water-matao o radiation wera rere pūoko, whakamahia nei te ki te ine i te radiation wera rere ānau o pereti radiation.
7. wai Kawe meangiti komuhumuhu pūrere e taea te tango atu i te wera mata o te mita rere wera.
8. Ka taea e tika te pūwera ngongo uku mahi i runga i te mata o te tauira whakamātautau i tuwhera ahi.
Ka taea e 9. rotor flowmeter whakarato hau ngingiha whakauru mō te pūwera ngongo uku.
Ka taea e ngāwari 10. Mass pūmana rere ine i te mahana o te mewaro mā te ine i te rere wera tino.
11. E ai ki ngā paerewa whakamātautau IMO, e taea te whakaratohia thermocouple whakaaro ki te ine i te wera auau tuku, me te tahi atu tawhā hāngai ana.
12. Ko te pūwera mewaro whakatika me te mewaro papatipu pūmana rere taea whakarato 1KW me 3KW mura pāmahana.
13. I roto i te whakamātautau, ka taea e te kāmera mau me te whakaora i te āhua inenga i roto i te hōtaka.
14. Rite rawa ki te whakaata e kitea te koki-whakarite, ka taea te kite i te auau mura horahanga roto whakaata karaihe, me te tauira rake i roto i te whakamātautau, a taea te tuhia aunoa i te pana waewae.
15. Rorohiko me te pūmanawa whakamātautau paerewa e whakamahia ana ki te whakahaere i te tukanga whakamātautau.
Product Feature of Horapa o Flame Kaiwhakamātau
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.
