Dab tsi yog cov txheej txheem xaiv rau lub ntsuas roj ruaj khov?
Yuav ua li cas xaiv lub ntsuas roj ruaj ruaj yog qhov tsim nyog rau cov neeg ua haujlwm soj ntsuam kev nyab xeeb? Ntau lub sijhawm ntau lawm yuav muaj cov nplaim hluav taws sib txawv, muaj kuab lom thiab muaj teeb meem organic gases. Yog li ntawd, nws yog ib qho tseem ceeb heev uas yuav tau xaiv qhov tseeb taag gas detector. Shenbei Technology Department yuav qhia qee qhov xwm txheej tshwj xeeb rau koj siv.
1. Yog tias feem ntau muaj methane thiab lwm yam tshuaj lom alkanes tsawg dua, nws yog qhov tsim nyog xaiv qhov ntsuas LEL. Lub hauv paus ntsiab lus ntawm kev tshawb nrhiav cov roj combustible yog catalytic combustion, uas yog ib qho kev tshawb nrhiav ntau heev. Nws kuj yog ib qho yooj yim heev rau ntsuas ntsuas calibration. Vim tias cov thev naus laus zis no tseem paub tab, cov khoom siv roj hauv tsev tuaj yeem ua tau raws li cov neeg siv khoom xav tau.
Cov nram qab no yog cov lus pom zoo hauv tsev rau cov khoom siv hluav taws xob hauv tsev thiab txawv teb chaws uas tau txais txiaj ntsig zoo los ntawm cov neeg siv: JL268D, JL269 leak detector, ADY-1, thiab HL-200 series cov neeg siv kuj tau teb kuj zoo. Ntshuam cov lus pom zoo: American Huarui FGM thiab SP series tsau roj ntes; Canadian BW lub tuam txhab MC-W combustible gas tswb; Honeywell Honeywell's ImpulseX1 ntes; COMCOS Tshiab Universe XP-3110 ntes, XP-3160 Pump-type tswb, XP-3140 leak detector; RAE Huarui miniEX portable combustible gas detector; OLDHAM EX2000 ntes; Drager PAC EX2, X-am 2000 combustible gas tswb. Yog tias muaj qee cov pa phem xws li carbon monoxide, hydrogen sulfide, ammonia, oxygen, hydrogen, phosphine thiab lwm yam gases, nws yuav tsum tau muab qhov tseem ceeb rau lub portable ib qho roj toxic detector lossis portable multi-gas detector kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm. Cov pa roj carbon monoxide detectors siv cov txheej txheem electrochemical los kuaj xyuas. Cov pa roj carbon monoxide detectors raws li cov txheej txheem electrochemical feem ntau ntsuas qhov concentration hauv ppm units. Nco tseg: Thaum kuaj pom cov pa phem no, ntxiv rau cov pa roj carbon monoxide thiab cov pa oxygen, cov pa phem hauv tsev tuaj yeem raug txiav txim siab. Rau lwm cov pa phem, nws raug nquahu kom siv cov khoom siv txawv teb chaws. Ntshuam cov lus pom zoo: BW ib qho tshuaj lom lub tswb nrov GAXT series; Honeywell ImpulseXP ib leeg ntes; Insco T40 Ntes; Oldham TX2000 ib leeg ntes; Dräger Pac 5000, pac7000, pac III ib leeg tshuaj lom lub tswb. . Yog hais tias muaj ntau cov organic toxic thiab teeb meem gases, xav txog qhov tsawg concentration uas yuav ua rau tib neeg lom, xws li aromatic hydrocarbons, halogenated hydrocarbons, ammonia (amines), ethers, alcohols, lipids, thiab lwm yam, photoionization yuav tsum tau xaiv. lub tshuab ntes tsis siv lub tshuab ntsuas LEL vim qhov no yuav ua rau tus kheej raug mob lossis tuag. Ntshuam cov lus pom zoo: American Huarui PGM-7360 benzene ntes, PGM-30 ntes, PGM-7320TVOC ntes, PGM-7340VOC ntes, Canadian BW tuam txhab M5 ntes thiab British ion organic detector .
Yog tias cov roj hom npog cov pa roj carbon monoxide saum toj no, xaiv cov khoom siv hluav taws xob sib xyaw. Qhov ntsuas no yuav tsum muaj cov pa roj ntawm qhov ntsuas qhov chaw, kom lub ntsuas ntsuas ntsuas tau zoo dua.
