Dab tsi yog qhov tseem ceeb uas yuav tsum tau xav txog thaum xaiv lub tswb nrov roj?
Toxic gas alarm, siv los xyuas cov pa roj carbon monoxide nyob rau hauv cov huab cua, nrog cov concentration qhia hauv ppm (ib feem lab) thiab cov pa oxygen qhia hauv cov nyiaj tau los lossis poob (feem pua VOL). Kev siv cov qib kev lag luam thiab kev ntseeg siab heev electrochemical lossis infrared sensors ua kom lawv cov kev ruaj ntseg siab thiab kev saib xyuas cov yam ntxwv tsis pub dawb, uas cuam tshuam txog qib ntawm kev txhim kho high-tech.
Kev xaiv lub tswb nrov roj yuav tsum xav txog cov hauv qab no:
1. Qhov tseeb yog tus qauv yooj yim rau kev ntsuas qhov zoo ntawm lub ntsuas roj. Yog hais tias hom thiab concentration ntawm cov roj pom tsis tuaj yeem ua kom pom tseeb, nws qhia tau hais tias qhov zoo thiab qhov ntsuas ntawm qhov ntsuas tsis tau raws li tus qauv. Hauv kev ua lag luam tam sim no, cov khoom siv hluav taws xob sib xyaw feem ntau muaj teeb meem ntawm kev cuam tshuam kev cuam tshuam hauv cov pa hluav taws xob, uas tuaj yeem cuam tshuam qhov tseeb. Yog li ntawd, ua ntej xaiv ib qho cuab yeej, nws yog ib qho tsim nyog yuav tau sab laj nrog cov chaw tsim khoom rau cov teeb meem cuam tshuam;
2. Kev tshuaj xyuas qhov ua haujlwm ntawm lub ntsuas ntsuas, seb nws puas zoo lossis tsis zoo, feem ntau yog nyob ntawm nws qhov ua tiav, xws li kev xa cov ntaub ntawv, lub tswb nrov, ceeb toom tas sijhawm, thiab lwm yam haujlwm, uas ua rau muaj kev nyab xeeb zoo heev;
3. Saib xyuas seb cov lus teb ceev ceev los yog tsis. Thaum kuaj xyuas cov ntaub ntawv, yog tias tus nqi tshaj qhov txwv, qhov xwm txheej ceev heev
Kev xaiv, kev ua yuam kev ntau, thiab kev ceev faj rau cov khoom siv roj
Qhov laj thawj yog vim li cas cov cuab yeej siv roj tsis tuaj yeem siv lossis puas yog qhov zoo tshaj plaws tsuas yog ib feem ntawm kev xaiv cov tuam txhab lag luam, feem ntau yog tshwm sim los ntawm kev xaiv thiab siv tsis raug.
Kev lees paub qhov yuam kev: Siv cov roj ntau ntau rau kev sim Case: Tom qab tus neeg siv khoom tau teeb tsa lub ntsuas hluav taws xob hluav taws xob ntawm qhov chaw, lawv siv lub teeb sib zog los ntsuas seb lub ntsuas puas ua haujlwm zoo. Tom qab ntsuas qhov cua, lub tswb ntsuas lub tswb tab sis tsis tuaj yeem rov pib dua rau xoom. Tom qab siv ib txwm siv thiab tshawb pom qhov kev puas tsuaj ntawm lub sensor, tag nrho cov sensors yuav raug xa rov qab mus rau lub Hoobkas kom them tus nqi hloov.
Kev Ntsuam Xyuas: Ntau tus neeg siv khoom nyiam siv cov pa roj ntau ntau rau kev sim thaum txais. Txoj kev no yog qhov tsis meej heev thiab tuaj yeem ua rau cov cuab yeej puas tsuaj. Kev tshawb nrhiav ntau yam ntawm cov khoom siv hluav taws xob hluav taws xob yog 0-100 feem pua LEL, nrog rau qhov kev txwv qis dua (methane yog 0-5 feem pua vol), thiab cov roj sib zog yog high-purity butane, uas deb tshaj qhov kev tshawb nrhiav ntau yam . Qhov ntau ntawm combustible gas detectors.
Thaum siv cov roj teeb sib zog rau kev sim, lub sensor yuav raug rau 2 mus rau 3 los yog siab dua qhov cuam tshuam, thiab cov tshuaj lom neeg ntawm cov khoom siv hluav taws xob yuav lwj lossis deactivate ua ntej, ua rau txo qis hauv kev tshawb pom qhov tseeb. Lub platinum hlau raug hlawv thiab lub sensor tau muab pov tseg. Nws yuav tsum raug sau tseg tias cov tuam txhab lag luam tsis tuaj yeem lav qhov tsis ua haujlwm sensor los ntawm kev cuam tshuam cov pa roj ntau thiab yuav tsum tau hloov ntawm lawv tus kheej cov nqi.
Kev tsom xam: Feem ntau cov khoom siv hluav taws xob uas muaj hluav taws xob nyob hauv khw siv lub hauv paus ntsiab lus ntawm catalytic combustion. Lub hauv paus ntsiab lus ntawm catalytic combustion yog siv lub zog catalytic los tsim kom muaj qhov kub thiab txias tsis tshua muaj hluav taws kub ntawm cov khoom siv catalytic, thiab qhov kub ntawm combustion nce qhov kub ntawm cov khoom.
