Yuav ua li cas siv combustible gas detector kom raug?
Flammable Gas Detector: Ib qho khoom siv uas ua rau ib lossis ntau qhov ntau ntawm cov pa taws. Combustible gas detectors tuaj nyob rau hauv ob hom: infrared optical thiab catalytic hom. Lub platinum hlau qhov saum npoo tau txais cov tshuaj tiv thaiv oxidation, los yog tsis muaj nplaim taws, thaum cov roj combustible nkag mus rau hauv lub ntes. Lub tshav kub uas ua rau lub platinum hlau qhov kub thiab txias thiab nws tsis kam hloov. Yog li yuav ua li cas koj ua haujlwm zoo ntawm cov khoom siv hluav taws xob hluav taws xob?
1. Tos 30 mus rau 60 vib nas this tom qab nias lub combustible gas detector lub hwj chim-on khawm. Koj tuaj yeem txav mus rau cov kauj ruam tom ntej thaum lub tshuab hluav taws xob hluav taws xob tau ua kom muaj zog thiab tag nrho cov txiaj ntsig zoo li qub ntawm lub vijtsam.
2. Teem lub portable flammable gas detector deb ntawm thaj chaw uas yuav tsum tau txheeb xyuas thiab muab sijhawm rau peb feeb. Qhov tseeb concentration tus nqi ntawm cov roj combustible yuav raug pom nyob rau hauv cov zaub thaum lub combustible gas detector tau pom tag nrho cov leakage concentration ntawm combustible gas nyob ib ncig ntawm. Qhov ntau ntawm kev ntsuas yog 0–100%LEL. Lub ntsuas hluav taws xob hluav taws xob yuav ua suab ceeb toom qis yog tias qhov ntsuas pom cov pa hluav taws xob pom tau ntau dua 25% LEL thiab tsawg dua 50% LEL.In thiaj li txhim kho cov neeg ua haujlwm hauv chaw tswj hwm cov roj hluav taws xob hauv ib puag ncig thiab ua tiav kev nyab xeeb thiab ntau lawm, lub combustible gas detector yuav emit high-frequency audible thiab pom lub tswb ceeb toom thaum lub teb chaws tsis muaj zog pom tias cov roj combustible to concentration ntau dua 50% LEL.
3. Tom qab siv tas, lub ntsuas hluav taws xob hluav taws xob yuav tsum tau khaws cia kom zoo. Qhov no suav nrog zeroing tus nqi thiab tu lub cuab yeej, tshwj xeeb yog lub taub hau. Nws tseem yuav tsum tau muab tua tsis tu ncua thiab them nyiaj raws li cov chaw tsim khoom cov lus qhia. Vim yog qhov hnyav ntawm ntau qhov chaw ua haujlwm ntawm qhov chaw, qhov chaw ntawm lub sensor yuav tsum tau tshem tawm cov plua plav kom sai li sai tau. Plua plav particle muaj peev xwm los thaiv cov nplaim hluav taws xob ntes sensor thiab txo nws qhov rhiab heev.
