Yuav ua li cas yuav tsum tau ua raws li thaum txhim kho cov pa roj toxic detectors nyob rau hauv lub tank ua liaj ua teb?
1, Installation qhov chaw:
Txiav txim siab lub installation qhov siab raws li qhov ceev ntawm cov pa phem. Thaum kuaj xyuas cov pa roj carbon monoxide hnyav dua li huab cua, qhov siab ntawm lub tshuab kuaj xyuas cov pa phem yuav tsum yog 0.3m ~ 0.6m ntawm pem teb (los yog hauv pem teb); Thaum kuaj pom cov pa roj carbon monoxide uas sib zog dua huab cua, qhov siab ntawm qhov ntsuas hluav taws xob yuav tsum tsis pub dhau 2.0m siab tshaj qhov tso tawm.
Thaum kuaj pom cov pa phem me ntsis hnyav dua li huab cua, qhov siab ntawm qhov ntsuas hluav taws xob yuav tsum yog 0.5m-1.0m hauv qab qhov tso tawm; Thaum kuaj pom cov pa roj carbon monoxide uas muaj qhov sib zog me ntsis ntawm huab cua, qhov siab ntawm cov khoom siv tshuaj lom yuav tsum yog 0.5m-1.0m siab tshaj qhov tso tawm.
2, Kab rov tav nrug:
Hauv cov chaw cia khoom thiab kev thauj mus los, kab rov tav qhov deb ntawm cov cuab yeej siv tshuaj lom thiab ib qho kev tso tawm hauv lawv thaj chaw yuav tsum tsis txhob siab tshaj 4m.
3, Installation ib puag ncig:
Lub tshuab hluav taws xob tshuaj lom neeg yuav tsum tau muab tso rau hauv qhov chaw uas tsis muaj kev cuam tshuam, kev co, muaj zog electromagnetic cuam tshuam, thiab yooj yim los tswj. Qhov kev tshem tawm ntawm qhov chaw kuaj xyuas qhov chaw thiab cov txheej txheem nyob ib puag ncig cov kav dej lossis cov khoom siv yuav tsum tsis pub tsawg dua 0.5m. Nws yog ib qho tsim nyog kom tsis txhob muaj qhov kub thiab txias, cov av noo siab, qhov chaw siab corrosiveness, nrog rau qhov chaw muaj cua thiab plua plav paug.
4, Installation method:
Tsau tshuaj lom neeg ntes tau tuaj yeem ntsia tau rau ntawm lub ru tsev, phab ntsa, lossis cov kav dej, ua kom muaj kev ruaj khov thiab txhim khu kev qha thaum txiav txim siab yooj yim ntawm kev saib xyuas thiab ntsuas.
5, Cov khoom siv hluav taws xob:
Kev siv hluav taws xob yuav tsum siv peb core shielded cables, nrog rau qhov nominal cross-sectional cheeb tsam ntawm ib lub xaim loj dua 1 square millimeter, thiab cov txheej thaiv thaiv yuav tsum tau ua hauv av thaum xaim. Kev xaim ntawm qhov chaw yuav tsum tau ua los ntawm cov kav dej uas ua tau raws li qhov yuav tsum tau muaj kev nyab xeeb ntawm hluav taws. Cov kav dej yuav tsum tau txuas nrog kev sojntsuam kom ua tau raws li qhov xav tau ntawm kev nyab xeeb hluav taws.
6, Cov pov thawj tawg thiab kev tiv thaiv:
Thaum cov khoom siv tshuaj lom neeg raug siv rau hauv qhov chaw tawg, nws yuav tsum muaj kev ua haujlwm tawg ua pov thawj raws li cov kev cai ntawm GB/T3836.1, GB/T3836.2 lossis GB/T3836.4, thiab tau txais cov ntawv pov thawj pov thawj pov thawj.
7, Tswb teeb tsa:
Thawj theem ceeb toom teeb tsa tus nqi rau cov pa roj carbon monoxide tsawg dua lossis sib npaug li 100% OEL, thiab qib thib ob lub tswb ntsuas tus nqi tsawg dua lossis sib npaug li 200% OEL. Thaum qhov ntsuas qhov ntsuas ntawm cov khoom siv hluav taws xob uas twb muaj lawm tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua, thawj theem lub tswb teeb tsa tus nqi ntawm cov pa phem yuav tsum tsis pub tshaj 5% IDLH, thiab theem ob lub tswb ntsuas tus nqi yuav tsum tsis pub tshaj 10% IDLH.
8, Kev saib xyuas tsis tu ncua thiab calibration:
Tsis tu ncua tswj thiab ntsuas cov pa roj toxic detectors kom ntseeg tau tias lawv ua haujlwm zoo.
