Qhov tseeb ntawm kev siv cov roj tua hluav taws
Raws li qhov yuav tsum ua kom muaj kev pov thawj ntawm cov hluav taws xob tua hluav taws yog qhov tseeb qhov tseeb, vim hais tias nws yog ib qho khoom siv hluav taws xob, feem ntau ntawm qhov kev pov thawj ntawm qhov kev tshawb xyuas qhov tseeb, tsis tas yuav tsum muaj tej qhov kub thiab txias, tseem yuav tsum tau qhov cua, tsis muaj yam khoom cuam tshuam los mus kuaj. Qhov no yog vim: vim qhov chaw kaw anoxia, ua rau muaj roj hlawv tsis tuaj yeem ua kom tiav combustion, hloov pauv hloov nrog cov combustion element resistant; ob, vim hais tias nkag mus rau cov hluav taws kub hnyav lossis cov pa phem thiab oxygen, combustion tsis tau tag nrho, vim li cas thiaj paub tsis tau qhov gas concentration; Peb, vim tias qhov concentration ntawm cov pa roj carbon monoxide nyob hauv ib puag ncig, txawm tias tuaj yeem ua kom tiav combustion, tab sis vim lawv qhov kev xav tau siab tshaj qhov ntsuas ntsuas ntau, , tom qab ib lub sij hawm, qhov kev hnov mob tau nce, yuav zoo heev rau qhov tseeb ntawm qhov kev xeem.
Cov kev qhia txog cov kauj ruam:
(1) tsos thiab hluav taws xob kos: rau siv nyob rau hauv lub tshuab hluav taws xob tua tau hluav taws xob hluav taws xob muaj qhov txawv ntawm qhov teeb meem, yuav tsum tau kuaj xyuas raws li cov kev cai tsim nyog.
(2) qhov tseeb ntawm qhov kev ua yuam kev: muaj kev ruaj khov hluav taws xob rau lub tshuab ua ntej, vim, nyob rau qee lub sijhawm ua haujlwm tom qab lub sijhawm tom qab qhib lub hwjchim ntawm lub tshuab raj yuav ruaj khov, cov cim pointer thaum lub sijhawm no yuav muaj qee qhov viav vias, qhov no tsuas yog lub xeev ntawm kev hloov, tsis ntes tsis ua hauj lwm, yog li xyuas kom ruaj lub sij hawm zoo rau kev ruaj ntseg yog tseem ceeb ntsuas kom ntseeg tau yooj yim kev ua yuam kev; tib lub sij hawm yuav tsum muab tus ntsuas calibration yuam kev rau tag nrho teev calibration, kuj yuav cuag lub hom phiaj ntawm tus qauv roj txuag.
Calibration ntawm yuam kev ntawm cov kauj ruam raws li nram no:
Ua ntej, txhua yam, raws li cov kev cai hais txog cov pa roj carbon dioxide uas muaj pes tsawg tus sib npaug, xoom, qhov fais fab yuav tsum ua kom tau raws li lub hwj huam uas yuav tsum tau ua raws li cov cai tswj kom ua tau, thiaj li coj tau cov xoom hluav taws xob.
Nyob rau hauv ib qho thib ob, kho tus nqi calibration, nrog cov roj txheem thaum lub sij hawm muaj tseeb, rau ntau yam twj paj nruag, los ntawm cov kev cai ntawm lub zog potentiometer ntawm qhov ntsuas kom ua tau raws li tus nqi calibration, qee qhov ntsuas tau hloov yog yuav rov ua ob lossis peb zaug .
Qhov thib peb, ua raws li cov kev cai ntawm kev txheeb xyuas kev pov hwm, raws li cov concentration ntawm li 10% LEL, 40% LEL, 60% LEL ntawm tus qauv roj, cov cuab yeej teev kev ntsuas tau ruaj khov rau hauv tus nqi, raws li cov kev sib tw tau noj cov nqi ntawm qhov loj tshaj rau cov nqi yuam kev.
Qeb plaub, thaum qhov kev ntsuam xyuas kom tau cov ntaub ntawv ruaj khov, rau kev ntsuas calibration yuav tsum tsis muaj cov concentration roj nyob rau hauv, maj mam mus rau qhov siab concentration ntawm roj.
Thib tsib, mus rau cov qauv ntawm cov concentration ntawm cov roj hauv qhov kev ntsuas ntawm qhov chaw dim pa stability, cov teeb, yuav ncav tau qhov tseeb thiab txhim khu kev npliag.
(3) lub repeatability ntawm qhov kev xeem: vim hais tias repeatability yog tom qab qhov tseeb ntawm tus nqi yuam kev ua, yog li koj tsis tuaj yeem nqa cov ntaub ntawv ntawm kev ua yuam kev, tab sis xav ua dua, nws yog xaus uas tus nqi.
Nyob rau hauv kev ua haujlwm, ua rau muaj qhov qis qhov calibration roj xoom, ces dhau mus rau qhov kev ntsuas roj zoo li 40% LEL, cov cuab yeej kaw tsis txaus, thiab raws li cov cai ua 6 zaug
