Product Feature and Application of the Surface Spread Flame Tester
Izixhobo 1.This iquka iqela radiation ekhwele nkqo kwindawo akuyo kwaye inkxaso kwi-sikhokelo.
2.The panel radiation ukuba zingcoliswe kunye umxube negesi-moya.
3.The panel imisebe 850mm isikwere ukuba uhlobo eliyinjubaqa block inkcukacha aneentunja eyenzelwe ukunika ukutshiswa ngokucikizekileyo umxube air-gas-moya, kungekho odangazelayo ezenzeka phezu kobuso lenjongo phantsi kweemeko zokusebenza.
4.The panel radiation kunye bayawarhawula yayo inkxaso kwi-sikhokelo ukuze embindini lenjongo imalunga 1250 ± 100mm ukusuka emgangathweni.
Umnini 5.A ndlovu kunye ilungiselelo pilot idangatye ekhwele ukuya kwelinye icala izixhobo.
6.The isibambi yomzekelo ziquka isakhelo ngensimbi yamanzi-zipholile ngamanzi-zipholile ubuso amacwecwe. Ubuso plates yi zinonxibelelwano le mbelukazi owe-20 ± 2mm ngaphezulu lwabo kunye nokuphela kwegqabi ezantsi kwaye phezu ngohlangothi nkqo ezikufutshane kwiphaneli yemisebe.
7.A spring zilayishwe eligaqa leyo ikwindawo ukubacinezela le ndlovu ngokuchasene ubuso amacwecwe.
8.The unikezelo lwamanzi eziphathwayo ukuba umnini ndlovu ukwenza lobushushu eliphezulu ayidluli 35 ℃ ngamashishini ukusuka umnini ndlovu.
9.The umnini ndlovu ibandla libekwe ku 90 ± 2 ° ebusweni kwiphaneli yemisebe yaye ezifana ngendlela ubuso phezulu kunye nezikhokelo ezantsi umnini ndlovu sele-moya efanayo njengoko ngaphakathi ubuso akuyo ku panel yemisebe.
10.The ukuphakama umnini yomzekelo yi kwakuxhomekeke ukuvumela ukuba esenza tye, kude nobuso kwiphaneli yemisebe phakathi iimvavanyo, ukususela uvavanyo kwindawo ukuya kwindawo yokulinda kunye nosekela-versa.
11.The pilot sokukhuphela yi iqulunqwe tube kuhlinzwa.
Imigca igesi kunye moya 12.The ukuya kwiphaneli yemisebe ziqulathe iimitha flow, nabalawuli uxinzelelo, iivelufa zolawulo kunye nezixhobo zokhuseleko.
13.Heat Flux Meter: Range: 0 ~ 50 kW / m2; Umphezulu emissivity: ɛ = 0.95 ± 0.05.
14.Dummy ibhodi yongqanianiso kunye kumnini, ukukala ngobhobhozo ubushushu imitha obandayo.
Product Iinkcukacha Surface Ukunaba Flame T Ester
Umphezulu flame isixhobo andise vavanyo a BS 6853 series-high speed flame sentsimbi nekudodobalisa tester, nto leyo efanelekileyo izinto zokwakha British ne-high speed flame intsimbi imigangatho nekudodobalisa uvavanyo. Umgangatho yi BS 476-7. Indlela Uvavanyo isetyenziselwa ukugqiba ukwandiswa osecaleni kumphezulu isampula kwaye zisekelwe phezu kwisantya. Kwaye ubude ukwandiswa imisela kwinqanaba otshisayo. BS 476-7 okokuqala kusetyenziswa nasekujongeni ukwandiswa ilangatye Imiphezulu bubhencekile wesilingi.
Indlela Uvavanyo kukulinganisa wobhobhozayo ebalulekileyo unyulu xa ekuqaliseni isampuli kunye ilangatye encinane ngokuthi withstanding utshintsho ngokuthe ngcembe kwamandla obushushu unyulu. Ubushushu obuma- Imilinganiselo yolawulo 850mm X 850mm. Umnini Uvavanyo yomzekelo ngamanzi zipholile kwaye mayixhotyiswe umlinganiselo kwimibhobho ipleyiti tubing kunye thermal bakhazimle nobhobhozayo woluvo ukuba uyenze le wobushushu kokukhanya obhobhozayo curve. Isixhobo test ineemfuno phezulu kwisiza elebhu, kwaye umsebenzisi ufuna amanyathelo angaphezulu okhuseleko phambi kokuba isixhobo uvavanyo ibandla.
