Product Feature and Application of the Surface Spread Flame Tester
Zida 1.This imakhala ndi cheza gulu wokwera vertically mu akuzinga ndipo anathandiza pa chimango ndi.
2.The gulu cheza ndi kuipitsidwa ndi osakaniza gasi mpweya.
3.The cheza gululi ndi 850mm lalikulu kwa porous refractory mtundu burner chipika chinakonzedwa kuti kuyaka nchito ya osakaniza mpweya gasi mpweya, ndi palibe lamoto zikuchitika pa nkhope ya gulu m'mikhalidwe ntchito.
4.The cheza gululi ndi akuzinga ake imayendetsedwa pa chimango kotero kuti likulu la gulu ili pafupi 1250 ± 100mm pamwamba pansi.
5.A chitsanzo chofukizira ndi makonzedwe woyendetsa lawi wokwera kuti mbali imodzi ya zida za.
6.The chitsanzo chofukizira ndiye mzati weni weni wa madzi utakhazikika zitsulozo ndi mbale madzi utakhazikika nkhope. The nkhope mbale ndi alipo pa toyesa 20 ± 2mm pamwamba awo ndi m'mbali pansi ndi pa m'mphepete ofukula pafupi ndi gulu cheza.
7.A masika yodzaza achepetsa ali pabwino kuti achepetsa ndi chitsanzo ndi mbale nkhope.
8.The kunyamula madzi okwanira kuti chofukizira chitsanzo kupanga pazipita kutentha si upambana 35 ℃ pa kubwereketsa ku chofukizira chitsanzo.
9.The chofukizira chitsanzo khamu ili pa 90 ± 2 ° ku nkhope ya gulu cheza ndi monga njira kuti nkhope ya pamwamba ndi atsogoleri pansi chofukizira chitsanzo ali mu ndege mofanana mkati nkhope ya akuzinga kwa gulu cheza.
10.The kutalika kwa chofukizira chitsanzo ndi kulumikizidwa walola kuti anaponya horizontally, kuchoka pa nkhope ya gulu cheza pakati pa mayesero, ku mayeso udindo kwa standby malo amtendere-inayo.
11.The woyendetsa burner ndi zigwirizana chubu zitsulo.
12.The mpweya ndi kotunga mpweya mizere ku gulu cheza muli otaya meters, owongolera kuthamanga, mavavu kulamulira ndi zipangizo chitetezo.
13.Heat kamwazi Meter: manambala: 0 ~ 50 kw / m2; Pamwamba emissivity: ɛ = 0,95 ± 0,05.
14.Dummy calibration bolodi ndi chofukizira, calibrated kutentha kamwazi mita ndi ogwiritsa.
Tsatanetsatane mankhwala a Surface Spread Flame T Ester
Pamwamba lawi kafalitsidwe mayeso chipangizo ndi BS 6853 zino mkulu-liwiro zitsulo lawi wamtundu uliwonse Tester, amene ali oyenera zipangizo British nyumba ndi mkulu-liwiro zitsulo lawi mfundo wamtundu uliwonse mayeso. Muyezo ndi BS 476-7. The njira mayeso ntchito kudziwa kutambasuka lateral a pamwamba nyemba ndi zochokera liwiro la. Ndipo utali kutambasuka Mzimuyo mlingo moto. BS 476-7 kwenikweni ntchito kuyeza lawi ukugwirizana pamalo poyera pa makoma ndi siling'i.
The njira mayeso ndi kuyeza yovuta chowala kamwazi ndi muyatsa chitsanzo ndi lawi aang'ono komabe kusintha mwapang'onopang'ono chowala kutentha mphamvu. Kutentha chowala gulu miyeso 850mm X 850mm. Mayeso chitsanzo chofukizira ndi madzi utakhazikika ndi okonzeka ndi calibration mbale perforated ndi matenthedwe chowala kamwazi sensa kukonza ikukhudzana kuwala kamwazi limaoneka lokongola. Kuyesedwa chida zofunika okwera pa malo choyezera, ndi wosuta ukusowa miyeso kwambiri chitetezo pamaso pa mayeso chida akhoza anasonkhana.
