Nyob rau hauv cov cheeb tsam uas muaj hydrogen yog nquag tsim,H2 Gas Detectorlos yog cov cuab yeej tshawb nrhiav hydrogen yuav tsum tau teeb tsa, thiab qhov ntsuas siab thiab qis ntawm cov cuab yeej yuav tsum tau teeb tsa kom raug. Thaum cov hydrogen (H2) concentration nyob rau hauv - ib puag ncig ntawm qhov chaw tshaj li tus qauv, tus neeg saib xyuas yuav tsum siv cov kev ntsuas kom tshem tawm qhov txhaum thiab ua kom muaj kev nyab xeeb ntawm kev tsim khoom.
Hydrogen gas detector yog ib qho cuab yeej siv los xyuas seb qhov concentration ntawm H2 hauv huab cua tshaj li tus qauv. Thaum cov pa taws kub hnyiab H2 nyob rau hauv ib puag ncig ncav cuag lossis tshaj qhov ua ntej -teeb tswb, tus maub los tam sim ntawd tso lub suab nrov thiab pom lub tswb kom ceeb toom rau tib neeg kom ntsuas kev nyab xeeb hauv lub sijhawm thiab tswj kev ua haujlwm ntawm lub tshuab nqus tsev lossis lwm yam khoom siv peripheral los tiv thaiv kev tawg thiab hluav taws kub, yog li ua kom muaj kev nyab xeeb ntawm lub neej thiab khoom.
1.Yuav ua li cas los teeb tsa tus nqi tswb ntawm hydrogen gas tswb ntsuas?
(1). Qhov tawg concentration ntau ntawm hydrogen yog 4% -75% VOL, thiab qis dua txwv LEL yog 4% VOL.
(2). Thawj - theem ceeb toom rau cov pa hluav taws xob tsawg dua lossis sib npaug li 25% LEL. Thaum lub tswb thib ob rau cov roj hluav taws xob tsawg dua lossis sib npaug li 50% LEL, nws tuaj yeem teem rau hauv kev coj nruj dua.
(3). Cov khoom siv hluav taws xob hluav taws xob feem ntau tau teeb tsa nrog ntau yam ntawm 0 txog 100% LEL.
(4). Yog tias tus nqi tswb tau teeb tsa qis dhau lawm, qhov tseeb ntawm lub tshuab ntes nws tus kheej yuav tsis ua raws li qhov yuav tsum tau ua, thiab xoom drift yuav ua rau lub tswb tsis tseeb.
Feem ntau ntawm cov hluav taws xob hluav taws xob hluav taws xob tam sim no muaj lawv lub tswb ntsuas qis qis ntawm 25% LEL. Ntawm no, 100% LEL yog hais txog qhov tawg txwv tus nqi ntawm cov roj. Qhov ntawd yog hais tias, thaum lub tswb hluav taws xob combustible qhia 100% LEL, nws nyuam qhuav mus txog qhov qis qis ntawm cov roj combustible.
2.Post-kev ceev faj txog kev kuaj xyuas hydrogen
(1) Lub tshuab kuaj xyuas hydrogen tau raug ntsuas rau cov roj ua ntej tawm hauv lub hoobkas. Tom qab kev teeb tsa, thov tsis txhob hloov cov khoom ntawm qhov xav tau. Yog xav tau kev hloov, recalibration yuav tsum tau.
(2) Lub neej ua haujlwm ib txwm siv ntawm lub tshuab ntsuas hydrogen yog peb xyoos. Vim muaj qhov sib txawv ntawm kev siv ib puag ncig, nws lub neej ntev yuav txo qis. Kev tshuaj xyuas thiab tu yuav tsum tau ua txhua xyoo.
(3). Siab -kev ua kom muaj zog hydrogen gas cuam tshuam yog nruj me ntsis txwv tsis pub ntawm thaj chaw hydrogen detector kom tsis txhob muaj tshuaj lom ntawm cov pa sensor thiab kev puas tsuaj rau lub ntes.
(4). Thaum lub sijhawm siv cov txheej txheem, nws yuav tsum tsis tu ncua xyuas seb lub ntsuas hluav taws xob hydrogen puas ua haujlwm zoo, thiab lub voj voog tshuaj xyuas yuav tsum yog tsawg kawg hauv peb lub hlis.
Hydrogen gas detectors muaj feem xyuam rau kev nyab xeeb ntawm kev siv hydrogen. Txhua qhov chaw muaj hydrogen, muaj peev xwm ntawm hydrogen tawg xwm txheej. Txawm hais tias qhov muaj peev xwm ua tau siab lossis tsis yog, peb yuav tsum tau ceev faj txog kev nyab xeeb kom tsis txhob muaj cov hydrogen concentration hauv qhov chaw ua haujlwm kom siab dhau thiab ncav cuag qhov qis qis ntawm hydrogen, uas tuaj yeem ua rau hluav taws kub thiab tawg thiab txawm tias raug mob.
