Kev piav qhia ntawm hom thiab ntau yam ntawm cov pa uas tau kuaj pom los ntawm plaub hauv ib lub tshuab ntes
Cov plaub hauv ib lub tshuab ntes roj tuaj yeem tshawb xyuas cov pa oxygen, hydrogen sulfide, carbon monoxide, thiab cov roj hluav taws xob. Hydrogen sulfide thiab carbon monoxide gases tuaj yeem sib xyaw nrog lwm cov pa roj raws li qhov kev xav tau ntawm qhov chaw. Gas detector feem ntau yog siv roj sensors los ntes cov pa roj hauv ib puag ncig.
Hom thiab ntau yam ntawm cov pa kuaj pom los ntawm plaub hauv ib lub ntsuas:
LEL ntau yam 0-100 feem pua LEL lossis 0-5 feem pua CH4;
O2 ntau yam 0-30 feem pua Vol;
CO ntau yam 0-500/2000ppm;
H2S ntau yam: 0-100/500ppm;
Kev ceev faj rau kev siv plaub hauv ib lub tshuab ntsuas roj:
1. Plaub nyob rau hauv ib qho yog cov khoom siv tiv thaiv tus kheej, thiab qhov ntsuas sab hauv ntawm qhov ntsuas yog txwv. Yog tias ntsuas roj ntau tshaj qhov ntau, nws tsis yooj yim los ntsuas rau lub sijhawm ntev, txwv tsis pub nws yuav ua rau muaj kev puas tsuaj rau lub sensor.
2. Thaum kuaj pom cov pa tshuaj lom, muaj teeb meem, thiab cov roj hluav taws xob, cov ncauj lus kom ntxaws tseem yuav tshwm sim tom qab tso tawm cov lus "siab" lossis "qis". Thov nyeem cov ncauj lus kom ntxaws. (LOW: low alert, HI: high alert)
3. Portable plaub hauv ib qho tuaj yeem tau txais kev cuam tshuam ntawm electromagnetic yoj, thiab thaum muaj kev cuam tshuam ntawm electromagnetic yoj, qhov ntsuas tus nqi yuav tsis raug. Thaum muaj kev cuam tshuam ntawm electromagnetic yoj, plaub hauv ib lub tswb yuav raug qhib, thiab qhov cuam tshuam ntawm electromagnetic yoj yuav raug tshem tawm ua ntej ntsuas.
4. Thaum siv plaub hauv ib qho, nws yog ib qho tseem ceeb uas yuav tsum tau xyuam xim rau cov roj teeb theem thiab hloov nws raws sij hawm thaum nws tsis txaus. Thov tsis txhob them tus nqi ntsuas ntawm qhov chaw sim kom tsis txhob muaj qhov tshwm sim los ntawm kev tshem tawm thiab ntsaws lub charger, uas tuaj yeem ua rau hluav taws kub lossis tawg.
5. Them rau thaj chaw nyab xeeb, hloov thiab them nqi raws sijhawm.
Thaum kuaj xyuas cov pa roj carbon monoxide, plaub hauv ib lub ntsuas roj yuav tsum xub ua tib zoo saib xyuas nws cov teeb meem uas tshwm sim: raws li cov tshuaj lom neeg ruaj khov ntawm cov pa roj carbon monoxide, hloov cov qib thiab lwm yam ntxwv ntawm cov concentrations siab. Vim lawv txoj kev vam khom rau qhov tsis muaj zog rub lub zog ntawm cov cua, lub sij hawm teb ntawm cov qauv feem ntau qeeb qeeb. Lub calibration ntawm plaub nyob rau hauv ib tug gas detector yog feem ntau nyuaj, uas yuav tsum tau hloov dua siab tshiab ntawm tshwj xeeb accessories thiab diffusion ntawm kev khiav hauj lwm hom los ntawm txaus calibration lub hom phiaj. Tsis tas li ntawd, qhov implied diffusion sib npaug ntawm cov ntws los ntawm kev saib xyuas thiab ntsuas ntsuas tsis yog ib qho ntaub ntawv zoo.
