Dab tsi yog qhov kev xaiv ntawm lub ntsuas roj ruaj khov?
Yuav ua li cas xaiv lub ntsuas roj teeb kom raug yog qhov tseem ceeb rau cov neeg soj ntsuam kev nyab xeeb? Cov xwm txheej tsim khoom sib txawv tuaj yeem muaj qhov sib txawv ntawm cov hluav taws kub, tshuaj lom, thiab cov pa phem organic. Yog li xaiv txoj cai tsau roj ntes yog qhov tseem ceeb heev. Shenbei Technology Department yuav qhia txog qee qhov xwm txheej tshwj xeeb rau koj siv.
1. Yog tias methane thiab lwm yam tshuaj lom alkanes tsawg dua, xaiv lub ntsuas LEL yog qhov kev xaiv zoo tshaj plaws. Lub hauv paus ntsiab lus ntawm combustible gas detection yog catalytic combustion, uas yog ib tug ntau nrhiav kom tau txoj cai. Lub calibration ntawm lub ntsuas kuj yog heev yooj yim. Vim tias cov thev naus laus zis no tseem paub tab, cov khoom siv hluav taws xob hauv tsev tuaj yeem ua tau raws li cov neeg siv khoom xav tau
Cov hauv qab no tau pom zoo hauv tsev thiab cov khoom siv roj av 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 zoo. Ntshuam pom zoo: Huarui FGM thiab SP series tsau roj ntes los ntawm Tebchaws Meskas; MC-W combustible gas tswb ntaus ntawv los ntawm Canadian BW tuam txhab; Honeywell's ImpulseX1 ntes; COMCOS Tshiab Universe XP-3110 ntes, XP-3160 twj tso kua mis tswb, XP-3140 leak detector; RAE Huarui miniEX portable combustible gas detector; Oldham EX2000 ntes; Drager PAC EX2, X-am 2000 combustible gas tswb ntaus ntawv. Yog tias muaj qee cov pa phem xws li carbon monoxide, hydrogen sulfide, ammonia, oxygen, hydrogen, phosphine, thiab lwm yam, yuav tsum tau muab qhov tseem ceeb rau kev xaiv lub portable ib qho roj detector los yog portable multi gas detector kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm. Lub tshuab hluav taws xob muaj kuab lom tau txais cov txheej txheem electrochemical rau kev tshawb nrhiav. Electrochemical gas detectors feem ntau ntsuas cov concentration hauv ppm units. Nco tseg: Thaum kuaj pom cov pa roj carbon monoxide thiab cov pa roj carbon monoxide, thaum kuaj pom cov pa roj carbon monoxide thiab cov pa oxygen, lwm cov pa phem uas tsis yog cov khoom tsim tawm hauv tsev tuaj yeem txiav txim siab. Nws raug nquahu kom siv cov cuab yeej txawv teb chaws. Rau kev ntshuam, nws raug nquahu kom siv BW ib leeg roj toxic tswb GAXT series; Honeywell ImpulseXP ib leeg ntes; Muaj Scientific T40 ntes; Odem TX2000 ib leeg ntes; Delge Pac 5000, Pac7000, pac III ib qho tshuaj lom neeg lub tswb ceeb toom yog tias muaj cov pa roj carbon monoxide ntau dua thiab cov pa phem, xav txog lawv cov qis qis uas yuav ua rau muaj kev phom sij rau cov neeg ua haujlwm, xws li cov tshuaj tsw qab hydrocarbons, halogenated hydrocarbons, ammonia (amine), ethers, cawv. , lipids, thiab lwm yam., yuav tsum xaiv lub photoionization detector es tsis txhob siv lub LEL detector, vim qhov no yuav ua rau raug mob. Ntshuam pom zoo: Huarui PGM-7360 benzene ntes los ntawm Tebchaws Meskas, PGM-30 ntes, PGM-7320TVOC ntes, PGM-7340VOC ntes, Canadian BW tuam txhab M5 ntes, thiab British ion organic compound detector.
Yog tias cov roj hom npog cov roj av saum toj no, xaiv cov khoom siv hluav taws xob sib xyaw uas yuav tsum muaj cov roj muaj pes tsawg leeg ntawm qhov ntsuas ntsuas kom zoo dua qhov ntsuas ntsuas ntsuas.
