Dab tsi yog qhov flammable gas detector qhov ntau?
Qhov kev tshawb nrhiav ntau yam ntawm cov khoom siv roj hluav taws xob feem ntau nyob hauv thaj tsam ntawm 0-100 feem pua LEL. Yog tias cov pa tawm ntawm cov pa hluav taws xob kuaj pom muaj 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. Thaum pom tias cov pa tawm ntawm cov roj combustible ntau dua 50 feem pua LEL, lub tshuab hluav taws xob combustible yuav emit lub suab nrov thiab lub teeb ceeb toom ceeb toom, txhim kho cov neeg ua haujlwm hauv chaw tswj cov roj combustible hauv ib puag ncig, yog li ua tiav. kev nyab xeeb thiab ua haujlwm tau zoo.
Dab tsi yog qhov ntau ntawm cov khoom siv hluav taws xob combustible
Cov khoom siv hluav taws xob hluav taws xob tuaj yeem ntes tau ntau cov roj hluav taws xob, xws li cov roj ntsha liquefied, cov pa roj carbon monoxide, ethane, acetylene, butane, n-butane, isobutane, pentane, hexane, halogenated hydrocarbons (chloromethane, methylene chloride, trichloroethane, vinyl chloride), Alcohols (methanol, ethanol, propanol), ethers, ketones (butanone, acetone), hydrogen Toluene thiab lwm yam sib txuas (roj av, muaj kuab tshuaj, xim, thinners, coolants, qhuav ntxuav kua, methyl acetate, thiab lwm yam).
LEL yog dab tsi?
LEL yog hais txog qhov kev txwv qis ntawm cov pa roj. Thaum cov roj hluav taws xob los yog cov kua hluav taws xob hluav taws xob (lossis cov plua plav hluav taws xob) sib xyaw nrog huab cua thiab nce mus txog ib qho concentration, nws yuav tawg thaum ntsib qhov hluav taws kub. Qhov concentration ntau yam uas tuaj yeem ua rau tawg yog hu ua explosive limit. Qhov qis dua qhov txwv ntawm txhua qhov roj sib txawv.
Qhov txwv tsis pub tawg ntawm cov pa roj hydrogen: qis dua 4.0 feem pua , qhov txwv siab tshaj 74.2 feem pua , combustion thiab tawg tshwm sim thaum ntsib huab cua thiab qhib nplaim taws. 4%. Yog tias nws tsawg dua cov kab hauv qab no, nws yuav tsis tawg thiab yuav tsis tawg thaum ntsib cov nplaim taws qhib. 74.2 feem pua yog qhov txwv siab tshaj plaws (lossis sab sauv txwv) ntawm cov khoom ntim siab tshaj plaws, saum toj no uas nws tuaj yeem muaj kev nyab xeeb ntawm huab cua thiab qhib nplaim taws yam tsis muaj kev tawg. Nyob rau hauv luv luv, qhov ntau yam nrog ib tug ntim feem hauv qab no los yog hauv qab ntawm lub tawg txwv yuav tsis tawg nyob rau hauv cov kev tshwm sim ntawm ib tug qhib nplaim taws.
Catalytic combustion type gas detectors yog siv los saib xyuas cov kev hloov pauv ntawm cov pa roj carbon monoxide hauv cov huab cua ib puag ncig los ntawm 0 mus rau 100 feem pua LEL. Lub sensor txais catalytic combustion tshuab thiab tuaj yeem hloov ntawm qhov chaw. Catalytic combustion sensors muaj ib tug ntse teb rau ntau yam ntawm combustible gases. Cov tshuab no muaj universal applicability rau combustible gases.
Combustible gas detectors yog gas detectors ntsia thiab siv nyob rau hauv industrial thiab civil vaj tse uas teb rau ib los yog ntau combustible gas concentrations. Cov khoom siv hluav taws xob feem ntau siv hauv lub neej niaj hnub yog catalytic combustible gas detectors thiab semi conductive combustible gas detectors.
Semiconductive combustible gas detectors feem ntau yog siv nyob rau hauv cov chaw xws li cov khw nojmov, tsev so, thiab cov chav tsev tsim khoom siv roj, natural gas, thiab liquefied gas. Catalytic combustible gas detectors feem ntau yog siv nyob rau hauv cov chaw ua lag luam uas emit combustible gases thiab vapors.
Cov saum toj no yog cov lus qhia muab los ntawm tus editor ntawm Shenzhen Liye hais txog qhov ntau ntawm cov roj combustible detectors. Peb vam tias nws yuav pab tau rau koj kom nkag siab txog cov khoom siv hluav taws xob hluav taws xob! Kev tu thiab tu cov khoom siv hluav taws xob tsis tu ncua yog ib txoj haujlwm tseem ceeb los tiv thaiv lawv los ntawm kev ua haujlwm tsis zoo.
