Umkhiqizo ukwethulwa le Into Single Burning
I Into Single Burning (SBI), indlela yokuhlola sokunquma asabela ngayo umlilo ukuziphatha ukwakha imikhiqizo (ngaphandle floorings) lapho zihlatshwa kuhlasela ezishisayo ngudokotela oyedwa esivuthayo lento (a isihlabathi kwebhokisi sikaphalafini bephethe propane). Isifanekiso igibele Sibona ukuthi ibekwe ohlakeni ngaphansi i ohlelweni qeda. Ukusabela kwama-ndlovu ukuze sikaphalafini kuyaqashwa instrumentally futhi zibukeke. Ukushisa kanye intuthu ukukhululwa amazinga kulinganiswa instrumentally nezici zomzimba ziyahlolwa ngokubona.
Umkhiqizo Isici futhi Isicelo le Into Single Burning
1.The Single Burning Into (SBI) siqukethe inqola, luhlaka emphahleni, hood igesi lokuqoqa, ngalendoda, J uhlobo qeda ipayipi, umlandeli centrifugal, umoya control ijubane kudivayisi, nesilinganiso oluphelele sigaba, igesi ukuhlaziywa iKhabhinethi, idatha ukuthola uhlelo;
2.The Sibona ingafakwa amabili mpo isampula zezinhlobo. Phansi engela mpo kuyinto isihlabathi ibhokisi sikaphalafini. Indlela ebusweni ukuthungela luyavunywa, uhlelo ilangabi ukuthola ifakwe njengoba idivayisi Ukuvikelwa flameout;
3.The Uhlaka fixed ukusekela igesi lokuqoqa kwenzakalani. Uhlaka fixed nge sikaphalafini asizayo futhi ifakwe uhlelo ilangabi uhlaliseke njengoba idivayisi Ukuvikelwa flameout;
4.Stainless steel igesi ngalendoda, elise phezulu ifreyimu fixed, esetshenziswa collect omlilo amagesi;
5.Stainless steel J uhlobo intuthu qeda igemfe, ububanzi kwangaphakathi (315 + 5) mm ne lokushisa 50mm okusezingeni eliphezulu amaminerali ukumelana ukotini ukwahlukanisa;
6.The uhlelo intuthu qeda shall intuthu ngokuqhubekayo qeda ngejubane 0.50m3 / s-0.65 m3 / s, futhi kumele kuhanjiswe ngokwezidingo zomThetho imvamisa ukuguqulwa;
7.Mass ageleze isilawuli, ukulinganisa uhla 0G / s-2.5g / s, ukufunda ukunemba hhayi ngaphansi kuka 1.5%;
8.Gas supply kungenziwa ngokuzenzakalelayo elawulwa ukuze flow rate of 647mg / s 2000mg / s, uhlelo lokulawula igesi kungaqinisekisa ijubane igesi supply inqubo izinguquko ukuhlolwa akufanele idlule 5mg / s, ukuqinisekisa okukhiphayo nokuvutha 30.7 + 2kW;
9.The flue igesi amasampuli iqukethe yesihlungi umlotha, nasesihibeni abandayo, omiswe amakholomu amabili, futha izibonelo zalokho futhi futha peristaltic, ukuze ngempumelelo ukwenza igesi isampula ihlanzekile futhi yomile;
10.Paramagnetic-mpilo analyzer, ukulinganisa uhla 0-25%, ukulinganisa-mpilo lokuhlushwa igesi, uhla lokuhlushwa 0-25%, T90 <imizuzwana 12; Non dispersive infrared CO2 analyzer: CO2: 0 ~ 10%;
11.A iphayiphi nge ubude 2155mm, ifakwe Uphenyo ingcindezi, thermocouples ezintathu, uphenyo igesi izibonelo zalokho, futhi uhlelo esimhlophe;
12.Two ngendlela uphenyo, nge uhla okungenani (0-100) Pa nokunemba 2Pa itheku ingcindezi inzwa axhunyiwe. Isikhathi Ukusabela ingcindezi inzwa 90% wokukhipha okungenani 1s;
13.The uhlelo ukukhanya kuyinto uhlobo esikhipha, nge (2900 + 100) K umbala lokushisa, kanye ngokuhlanganyela nezimo efakwe ohlangothini ipayipi qeda;
14.Silicon photodiode umtshina, nge 0.1% komugqa ukuzinza;
15.The emoyeni busuka ohlangothini tube ukulondoloza ukuhlanzeka kudivayisi optical, okuyinto Kungafezani emoyeni onomfutho;
Application:It is suitable for the testing the fire resistance of building materials / products in single burning item (SBI).
