Cov yam tseem ceeb uas cuam tshuam rau kev ntsuas ntawm qhov ntsuas kub ntawm qhov ntsuas kub ntawm lub thermocouple feem ntau suav nrog lub sijhawm teb, thermal impedance nce thiab thermal tawg. Cia's ua tib zoo saib nws hauv qab no.
Teb sijhawm
Lub hauv paus ntsiab lus ntawm kev ntsuas qhov kub thiab txias yog qhov ntsuas qhov ntsuas kub yuav tsum ncav cuag thermal sib npaug nrog cov khoom ntsuas. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tswj xyuas qee lub sijhawm thaum ntsuas kub kom ua tiav qhov sib npaug ntawm qhov sib npaug ntawm ob. Qhov ntev ntawm lub sijhawm tuav yog cuam tshuam nrog lub sijhawm thermal teb ntawm qhov ntsuas qhov ntsuas kub. Lub sij hawm teb thermal feem ntau yog nyob ntawm tus qauv ntawm lub sensor thiab cov kev ntsuas ntsuas, uas txawv heev. Rau cov xov xwm gaseous, tshwj xeeb tshaj yog cov roj zoo li qub, nws yuav tsum tau khaws cia tsawg kawg 30 feeb kom ncav cuag qhov sib npaug; rau cov kua, qhov ceev tshaj plaws yuav tsum yog tsawg kawg 5 feeb. Rau qhov chaw nyob rau hauv kev sim nrog qhov kub thiab txias tas li, tshwj xeeb tshaj yog cov txheej txheem hloov pauv tam sim, tag nrho cov txheej txheem tsuas yog 1 thib ob, thiab lub sijhawm teb ntawm lub sensor yuav tsum nyob rau hauv millisecond theem. Yog li ntawd, qhov ntsuas kub zoo tib yam tsis tsuas yog tuaj yeem' tsis tuaj yeem ua raws li qhov kub thiab txias hloov ceev ntawm cov khoom ntsuas, tab sis kuj muaj qhov ntsuas qhov yuam kev vim tsis muaj peev xwm ncav cuag qhov ntsuas kub. Nws yog qhov zoo tshaj los xaiv lub sensor uas teb sai sai. Rau cov thermocouples, ntxiv rau qhov cuam tshuam ntawm cov raj tiv thaiv, txoj kab uas hla ntawm qhov ntsuas qhov kawg ntawm lub thermocouple kuj yog qhov tseem ceeb, uas yog, lub thinner lub coupling hlau, qhov me me ntawm txoj kab uas hla ntawm qhov ntsuas kawg, thiab luv dua. thermal teb lub sijhawm.
Ua kom thermal tsis kam
Rau cov thermocouple kub sensors siv nyob rau hauv qhov kub thiab txias, yog hais tias qhov nruab nrab ntsuas yog gaseous, cov plua plav tso rau ntawm qhov chaw ntawm lub raj tiv thaiv yuav yaj rau ntawm qhov chaw, ua rau lub thermal kuj ntawm lub raj tiv thaiv; Yog hais tias qhov ntsuas nruab nrab yog yaj, Slag deposits thaum siv, uas tsis tsuas yog nce lub sij hawm teb ntawm lub thermocouple, tab sis kuj txo qhov ntsuas kub. Yog li ntawd, ntxiv rau kev tshuaj xyuas tsis tu ncua, txhawm rau txo qhov yuam kev, kev tshuaj xyuas tsis tu ncua kuj tseem tsim nyog. Piv txwv li, lub qhov cub hluav taws xob tuaj txawv teb chaws tsis yog tsuas yog nruab nrog qhov ntsuas kub tsis tu ncua ntsuas qhov ntsuas kub ntsuas thermocouple, tab sis kuj tau nruab nrog cov khoom siv ntsuas kub ntsuas kub, uas yog siv los ntsuas qhov tseeb ntawm qhov ntsuas kub tsis tu ncua ntsuas lub sijhawm.
Kub hluav taws xob
Lub thermocouple kub sensor tso rau hauv lub qhov cub rau qhov ntsuas kub yuav raug cua sov los ntawm thermal tawg tawm los ntawm cov khoom kub kub. Nws tau xav tias cov roj hauv lub cub tawg yog pob tshab, thiab thaum qhov sib txawv ntawm qhov kub thiab txias ntawm cov thermocouple thiab cov phab ntsa ntawm lub cub tawg loj, qhov ntsuas kub tsis raug yuav tshwm sim vim kev sib pauv hluav taws xob. Feem ntau, txhawm rau txo qhov kev ua yuam kev thermal tawg, kev siv hluav taws xob yuav tsum tau nce ntxiv, thiab cov phab ntsa ntawm lub cub tawg yuav tsum nyob ze li sai tau rau qhov kub ntawm lub thermocouple. Tsis tas li ntawd, qhov kev teeb tsa ntawm lub thermocouple yuav tsum nyob deb li deb tau ntawm cov hluav taws xob hluav taws xob tawm ntawm cov khoom, kom nws tsis tuaj yeem tawg mus rau saum npoo ntawm lub thermocouple; Lub thermocouple yuav tsum zoo dua yog nruab nrog lub tshav kub hluav taws xob tiv thaiv lub tes tsho.
