Yuav ua li cas kom raug lub tshuab ntes roj thiab yuav tsum tau ceev faj dab tsi ua ntej siv?
Rau kev lag luam xws li tshuaj lom neeg, roj, thiab metallurgical, kev tshawb nrhiav roj yog ib qho tseem ceeb ntawm txoj kev nyab xeeb vim tias muaj cov pa taws thiab ua pa tawm hauv cov txheej txheem tsim khoom, uas feem ntau corrosive thiab tuaj yeem ua rau mob hnyav thaum nkag mus rau tib neeg lub cev los ntawm kev ua pa. Yog li ntawd, gas detectors tau dav siv nyob rau hauv ntau yam lag luam.
Ua ntej siv lub tshuab ntsuas roj:
① Ua tib zoo nyeem cov neeg siv phau ntawv coj mus rau lub ntsuas roj ua ntej ua haujlwm tom tsev, paub koj tus kheej nrog kev ua haujlwm thiab kev ua haujlwm ntawm lub tshuab.
② Xyuas seb lub roj teeb puas tau them tag nrho, thiab hloov nws tam sim yog pom tias nws qis.
③ Tshawb xyuas seb puas muaj cov khoom txawv teb chaws thaiv cov cua lim. Yog tias nws raug thaiv, nws yuav tsum tau muab ntxuav los yog hloov.
④ Nias thiab tuav lub pob pib rau peb vib nas this thaum pib nkag mus rau tus kheej - kuaj hom. Saib xyuas seb tus nqi tswb qis thiab tus nqi ceeb toom siab los ntawm lub tshuab ntes yog qhov tseeb (CO detector muaj thawj theem tswb ntawm 50ppm thiab lub tswb thib ob ntawm 100ppm); Thawj theem tswb ntawm lub ntsuas pa oxygen yog 19.5%, thiab lub tswb theem thib ob yog 22%; Hydrogen sulfide detector muaj thawj theem tswb ntawm 10 ppm thiab lub tswb theem thib ob ntawm 15 ppm. Yog tias nws tsis ua raws li qhov yuav tsum tau ua, nws tsis tuaj yeem siv thiab yuav tsum tau ntsuas tam sim.
⑤ Thaum lub sijhawm kuaj tus kheej thaum lub sijhawm pib, nws yuav tsum tau mloog lub tswb ntsuas qib, lub suab nrov thiab lub tswb nrov, thiab lub tswb vibration kom pom tias lawv muaj tseeb. Yog tias lawv tsis ua raws li qhov yuav tsum tau ua, lawv tsis raug tso cai siv thiab yuav tsum tau ntsuas tam sim ntawd.
⑥ Tom qab pib nyob rau hauv cov huab cua ntshiab, saib seb tus nqi pib yog qhov tseeb (CO detector thawj zaug qhia 0 ppm; thawj qhov pom ntawm O2 detector yog 20.9%; thawj zaug tso saib ntawm hydrogen sulfide detector yog 0 ppm. Yog hais tias tus nqi tso tawm tsis raug, nws yog nruj me ntsis txwv tsis pub siv thiab yuav tsum tau calibrated tam sim ntawd.
