Qhov kev tshawb nrhiav ntau yam ntawm cov khoom siv hluav taws xob hluav taws xob feem ntau nyob hauv 0-100 feem pua LEL. Yog tias qhov kuaj pom cov pa tawm hluav taws xob ntau dua 25 feem pua LEL thiab tsawg dua 50 feem pua LEL, lub tshuab hluav taws xob hluav taws xob hluav taws xob yuav tawm lub tswb qis. Piv txwv li, thaum lub concentration ntawm combustible gas leakage ntau dua 50 feem pua LEL, lub combustible gas detector yuav muab ib tug high-frequency suab thiab lub teeb ceeb toom ceeb toom teeb liab los txhim kho lub on-site neeg teb xov tooj kev tswj ntawm combustible gas nyob rau hauv ib puag ncig, thiaj li. kom ua tiav kev nyab xeeb thiab ua haujlwm tau zoo.
Shenzhen Liye: Dab tsi yog qhov ntau ntawm cov khoom siv hluav taws xob hluav taws xob?
Lub combustible gas detector yuav ntes tau ntau combustible gases, xws li natural gas, liquefied gas, thee gas, ethane, acetylene, butane, n-butane, isobutane, pentane, hexane, halogenated hydrocarbons (chloromethane, Methylene chloride, trichloroethane, vinyl). , alcohols (methanol, ethanol, propanol), ethers, ketones (butanone, acetone), hydrogen, toluene thiab lwm yam sib txuas (gasoline, industrial solvents, xim, thinners, coolant, qhuav tu kua, methyl acetate, thiab lwm yam).
LEL yog dab tsi?
LEL yog hais txog qhov txo qis ntawm qhov tawg ntawm cov pa. Thaum lub vapor ntawm combustible gas, combustible kua (los yog combustible plua plav) yog tov nrog huab cua thiab mus txog ib tug tej yam concentration, nws yuav tawg thaum nws ntsib qhov hluav taws kub. Qhov concentration ntau yam uas tuaj yeem tawg tau yog hu ua qhov txwv tawg. . Qhov qis dua qhov txwv ntawm txhua qhov roj sib txawv.
Piv txwv li, qhov txwv kev tawg ntawm hydrogen: qhov txwv qis dua yog 4.0 feem pua, qhov txwv sab saud yog 74.2 feem pua, thiab nws yuav hlawv thiab tawg thaum nws ntsib huab cua thiab qhib nplaim taws. 4%. Yog tias nws tsawg dua qhov kab hauv qab no, nws yuav tsis hlawv thiab tawg yog tias nws ntsib cov nplaim taws qhib. 74.2 feem pua yog qhov txwv sab sauv (lossis sab sauv txwv) ntawm feem ntau tshaj plaws. Thaum lub ntim feem ntau siab tshaj qhov kev txwv saum toj no, nws tuaj yeem hlawv yam xyuam xim thaum muaj huab cua thiab qhib nplaim taws, thiab yuav tsis tawg. Nyob rau hauv luv luv, yog hais tias lub ntim feem yog qis dua los yog qis dua qhov kev txwv tawg, tsis muaj qhov tawg yuav tshwm sim nyob rau hauv rooj plaub ntawm cov nplaim taws qhib.
Catalytic combustion gas detector yog siv los saib xyuas qhov kev hloov pauv ntawm cov pa roj combustible nyob ib puag ncig huab cua los ntawm 0 mus rau 100 feem pua LEL. Lub sensor siv catalytic combustion technology thiab lub sensor tuaj yeem hloov pauv hauv thaj chaw. Catalytic combustion sensors yog rhiab heev rau ntau yam ntawm cov nplaim taws. Cov thev naus laus zis no muaj kev siv dav dav rau cov pa hluav taws xob.
Lub combustible gas detector yog ib tug gas detector ntsia thiab siv nyob rau hauv industrial thiab civil vaj tse uas teb rau cov concentration ntawm ib los yog ntau combustible gases. Cov khoom siv hluav taws xob ntau tshaj plaws yog catalytic combustible gas detectors thiab semiconductor combustible gas detectors.
Cov chaw uas siv cov pa roj, cov pa roj ntsha thiab cov roj liquefied hauv cov khw noj mov, tsev so, thiab cov chav tsim khoom hauv tsev feem ntau siv cov khoom siv hluav taws xob semiconductor-hom combustible gas detectors, thiab cov chaw lag luam uas tawm cov roj combustible thiab combustible steam mas siv catalytic-type combustible gas detectors.
