Gas detector dab tsi yog kev siv ntawm kev nkag siab yuam kev, dab tsi yog kev ceev faj
Gas detector yog cov cuab yeej siv hluav taws xob tso tawm kom pom cov pa tawm, suav nrog: portable gas detector, handheld gas detector, fixed gas detector, on-line gas detector, etc. , gas sensor yog siv los xyuas qhov muaj pes tsawg leeg thiab cov ntsiab lus ntawm cov roj sensor. Hauv kev siv cov txheej txheem, vim tsis tuaj yeem siv lub tshuab ntsuas roj lossis puas vim qhov ua tau zoo tsuas yog ib feem ntawm kev xaiv ntawm cov tuam txhab lag luam zoo tib yam, feem ntau yog vim kev xaiv tsis raug thiab siv tsis raug. Yog li koj puas paub dab tsi yog lub tshuab ntsuas roj siv yuam kev?
Gas detector siv yuam kev:
Kev lees paub qhov yuam kev: siv cov roj ntau ntau rau kev sim: cov neeg siv khoom hauv thaj chaw tom qab kev teeb tsa ntawm cov khoom siv hluav taws xob, kev siv lub teeb los kuaj seb lub ntsuas puas ua haujlwm zoo. Tom qab kuaj qhov cua, lub tshuab ntes tau ceeb toom tab sis tsis tuaj yeem rov pib dua rau xoom. Kev siv ib txwm, kuaj pom tias lub sensor puas lawm, tag nrho rov qab mus rau lub Hoobkas kom them tus nqi hloov.
LEEJ TWG: Ntau tus neeg siv khoom nyiam siv cov pa roj ntau rau kev sim thaum txais. Txoj kev no yog qhov tsis raug thiab tuaj yeem ua rau kev puas tsuaj rau lub cuab yeej. Kev tshawb nrhiav ntau yam ntawm cov khoom siv hluav taws xob hluav taws xob yog {{0}}} ~ 100% LEL, nrog qis qis qis qis (0 ~ 5% vol rau methane), thiab cov roj sib zog yog high-purity butane, uas yog deb dhau qhov kev tshawb nrhiav ntau yam.
Kev Xeem yuam kev: Thaum kuaj nrog cov roj sib zog, lub sensor yuav raug rau 2 mus rau 3 lossis ntau qhov kev poob siab thiab cov tshuaj lom neeg ntawm cov khoom siv hluav taws xob yuav lwj lossis deactivate ntxov ntxov, ua rau txo qis kev tshawb pom. Lub platinum hlau yog burnt tawm thiab lub sensor yog scrapped. Nws yuav tsum raug sau tseg tias cov chaw tsim khoom tsis tuaj yeem lav qhov tsis ua haujlwm ntawm lub sensor los ntawm cov pa roj ntau 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 tsis tshua muaj hluav taws kub ntawm cov khoom siv catalytic, qhov kub ntawm combustion nce qhov kub ntawm lub caij.
