Dab tsi Ua Thermocouples nrog Cov Txheej Txheem Tshwj Xeeb Zoo rau Kev Ntsuas Kub Kub?

Thermocouples npaj nrog cov rwb thaiv tsev tshwj xeeb muaj ntau tus yam ntxwv uas ua rau lawv tsim nyog rau kev ntsuas kub ntau dhau.
Cov khoom siv hluav taws xob tshwj xeeb uas siv tau yog tsim los tiv thaiv qhov kub thiab txias ntau yam tsis muaj kev puas tsuaj los yog poob lawv lub tsev insulating. Qhov no tau lees paub tias qhov hluav taws xob kos npe tsim los ntawm txoj kev ntawm lub thermocouple nyob twj ywm raug thiab tsis cuam tshuam los ntawm txoj kev ntawm kev sov so-nqa los ntawm kev kho nyob rau hauv lub rwb thaiv tsev.
Cov rwb thaiv tsev no muaj cov thermal conductivity tsawg, txo cov cua sov hloov ntawm ib puag ncig mus rau cov xaim thermocouple. Qhov no ua rau kom qhov kub thiab txias gradient thoob plaws hauv kev sib tshuam thiab txhim kho qhov tseeb qhov tseeb ntawm txoj kev ntawm kev txo qis qhov sov sov.
Cov rwb thaiv tsev tshwj xeeb feem ntau qhia tawm thawj tus nqi tiv thaiv thermal shock. Lawv tuaj yeem tiv taus qhov kub thiab txias hloov nrog kev tawg lossis deforming, uas yog qhov tseem ceeb hauv cov pob khoom uas qhov kub sib txawv feem ntau lossis sai.
Lawv kuj tseem muaj pov thawj tiv thaiv oxidation thiab tshuaj degradation ntawm qhov kub thiab txias. Qhov no ua rau lub neej ntev ntawm cov rwb thaiv tsev thiab cov thermocouple nws tus kheej, ua kom ntseeg tau tias kev taug qab ntev ntev.
Cov rwb thaiv tsev yuav muaj lub zog dielectric ntau dhau, txwv tsis pub hluav taws xob tawg thiab ua kom muaj kev tiv thaiv thiab kev ncaj ncees ntawm cov cuab yeej dimension txawm nyob rau hauv qhov kub thiab txias, hluav taws xob ib puag ncig.
Cov rwb thaiv tsev tshwj xeeb yuav raug tsim los kom muaj qhov porosity tsawg, txwv tsis pub cov roj nkag los yog cov pa paug uas yuav ua rau muaj kev cuam tshuam rau tag nrho cov kev ua tau zoo ntawm cov thermocouple los yog vim li cas cov rwb thaiv tsev tsis ua haujlwm.
Lawv kuj tseem tuaj yeem muaj cov tsev nyob hauv qhov hluav taws kub, nrog rau cov txheej txheem ntxiv ntawm kev tiv thaiv hauv cov pob kub ntau dhau qhov uas muaj kev phom sij rau lub plawv muaj kev txhawj xeeb.
Kev sib xyaw ntawm cov tsev no cia rau hauv cov thermocouple ua haujlwm tsis tu ncua thiab raws li nws yuav tsum nyob rau hauv cov xwm txheej kub ntau dhau qhov uas nyiam cov rwb thaiv tsev yuav ua tsis tau lossis cuam tshuam qhov zoo ntawm qhov ntev.
Txawm li cas los xij, nws yog ib qho tseem ceeb los xaiv qhov tseeb ntawm cov rwb thaiv tsev tshwj xeeb raws li tag nrho ntawm qhov kub thiab txias, qhov xwm txheej ib puag ncig, thiab kev ceeb toom yuav tsum tau sau cov txiaj ntsig zoo tag nrho.
