Plaub-hauv-ib Gas Detector Hydrogen sulfide tswb tus nqi qauv
Kev teeb tsa ntawm lub tswb ntsuas hydrogen sulfide tus nqi ntawm 4-hauv-1 gas detector yog ib qho tseem ceeb heev, thiab nws yuav tsum tau ua raws li cov qauv thiab cov kev cai los txiav txim seb tus nqi tsim nyog. Hydrogen sulfide yog cov pa phem heev uas ua rau tib neeg lub cev thiab ib puag ncig, yog li kev tshawb pom ntxov thiab ceeb toom yog qhov tseem ceeb.
Raws li lub teb chaws tus qauv GBZ 2. Cov qauv no muab ntau qhov kev pom zoo ntawm hydrogen sulfide hauv chaw ua haujlwm.
Raws li lub teb chaws tus qauv GB/T {{0}} Petrochemical Combustible thiab Toxic Gas Detection thiab Tswb Design Standards, qhov ntsuas ntau yam ntawm cov pa phem yuav tsum yog 0 ~ 300% OEL, thiab OEL yog 10mg/m3. Thawj tus nqi tswb yuav tsum tsawg dua lossis sib npaug rau 100% OEL, piv txwv li 10mg / m3, thiab tus nqi tswb thib ob yuav tsum tsawg dua lossis sib npaug li 200% OEL, piv txwv li 20mg / m3. Thaum qhov ntsuas qhov ntsuas ntawm qhov ntsuas uas twb muaj lawm tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua, tus nqi ceeb toom tseem ceeb yuav tsum tsis pub tshaj 5% IDLH thiab tus nqi tswb thib ob yuav tsum tsis pub tshaj 10% IDLH.
Cov kev cai dav dav ntawm cov qauv saum toj no, peb tuaj yeem muab cov hauv qab no plaub-hauv-ib lub ntsuas roj hydrogen sulfide lub tswb ntsuas tus nqi teeb tsa cov lus qhia:
1. Kev ntsuas ntau: 0~30mg/m3, uas yog sib npaug rau 0 ~ 20ppm ntim concentration.
2. thawj theem ntawm lub tswb ntsuas qis qis (AL): tsis ntau tshaj 10mg / m3, uas yog, tsis ntau tshaj 6.5ppm ntim concentration.
3. Secondary high alarm setting value (AH): tsis tshaj 20mg/m3, piv txwv li tsis tshaj 12ppm ntim concentration.
Qhov ntau ntawm lub tswb ntsuas qhov tseem ceeb hauv txoj kev no ua kom lub tswb nrov raws sijhawm thaum muaj kev nyab xeeb siab tshaj, tiv thaiv kev noj qab haus huv thiab lub neej ntawm cov neeg ua haujlwm.
Hauv kev xaiv ib qho tshwj xeeb 4-hauv-1 gas detector, koj yuav tsum xyuam xim rau nws qhov zoo thiab kev ua tau zoo. Lub tshuab ntsuas roj zoo yuav tsum yog tus yam ntxwv ntawm qhov raug siab, siab rhiab heev, teb ceev ceev, ruaj khov thiab kev ntseeg tau. Tib lub sijhawm, cov cuab yeej siv tau yooj yim rau kev khiav lag luam, txav tau yooj yim thiab yooj yim, thiab tuaj yeem ua tau raws li qhov xav tau ntawm qhov chaw ua haujlwm sib txawv thiab kev xav tau.
