Lwm qhov txiaj ntsig tseem ceeb ntawm tungsten-rhenium thermocouples yog lawv cov kav ntev. Lawv raug tsim los tiv thaiv cov mob hnyav ntawm qhov kub thiab txias, suav nrog kev ntxhov siab, oxidation, thiab thermal shock. Cov thermocouples 'alloys no muaj lub neej ua haujlwm ntev thiab txhim khu kev qha vim lawv tiv taus hnav thiab tsim kua muag. Tungsten-rhenium thermocouples tuaj yeem siv los saib xyuas qhov kub thiab txias hauv lub zeb zeb uas cov hlau molten raug kho ntawm qhov kub siab heev. Cov thermocouples no tuaj yeem muab tso rau ntawm cov kab ntau lawm lossis hauv qhov cub. Cov thermocouples no tuaj yeem muab cov ntawv nyeem meej rau lub sijhawm ntev txawm tias nyob rau hauv lub ntsej muag ntawm qhov xwm txheej hnyav, uas txo qis qis qis thiab xav tau kev hloov pauv ntau zaus.
Tungsten-rhenium thermocouples yog qhov ruaj khov ntawm qhov kub thiab txias thiab muab qhov ntsuas kub zoo. Vim tias cov yam ntxwv thermal ruaj khov ntawm cov ntaub ntawv siv hauv lawv qhov chaw tsim khoom, qhov ntsuas kub tau lees paub yog qhov tseeb thiab tas li. Hauv cov ntawv thov uas txawm tias qhov ntsuas kub me ntsis tuaj yeem cuam tshuam rau cov txheej txheem lossis qhov zoo ntawm cov khoom kawg, qhov no yog qhov tseem ceeb. Piv txwv li, tungsten-rhenium thermocouples tuaj yeem siv los saib xyuas qhov ntsuas kub ntawm cov khoom siv hauv cov khoom siv hluav taws xob, qhov kev tswj qhov kub thiab txias yog qhov tseem ceeb rau kev tsim cov chips zoo. Cov thermocouples 'cov ntsuas qhov kub thiab txias ua rau muaj qhov sib xws thiab caliber ntawm cov khoom siv semiconductor uas tau tsim.
Lwm qhov zoo tshaj plaws ntawm tungsten-rhenium thermocouples yog lawv qhov hloov tau. Lawv muab ntau yam kev ntsuas kub thiab kev teeb tsa thiab tej zaum yuav raug kho kom haum raws li qhov tshwj xeeb xav tau ntawm ntau yam kev siv. Tungsten-rhenium thermocouples tuaj yeem hloov kho kom tau raws li cov kev cai tshwj xeeb ntawm ib puag ncig, txawm tias nws yog kev lag luam loj lossis lub qhov cub kub kub hauv qhov chaw tshawb fawb. Lawv yog cov cuab yeej siv tau zoo rau ntau yam kev lag luam thiab kev siv vim tias lawv muaj ntau yam.
Tungsten-rhenium thermocouples muaj qee qhov tsis zoo, txawm li cas los xij, zoo li lwm yam thev naus laus zis. Tus nqi ntawm lawv yog ib qho ua tau tsis zoo. Cov thermocouples no yuav raug nqi ntau dua li cov thermocouples ib txwm siv vim tias siv cov khoom siv tsawg thiab kim heev thiab cov txheej txheem ntau lawm uas xav tau. Rau qee cov ntawv thov uas cov nyiaj yog qhov tseem ceeb, qhov no tuaj yeem yog qhov teeb meem. Txhawm rau kom ntseeg tau kev nyeem ntawv, kev teeb tsa thiab ntsuas ntsuas yuav tsum ua kom raug. Cov thermocouples no ua haujlwm nyob rau hauv qhov chaw kub kub, uas yuav ua rau kev txhim kho thiab kev saib xyuas nyuaj thiab hu rau qee yam kev txawj thiab cov cuab yeej.
Thaum kub kub heev, tungsten-rhenium thermocouples muab kev ua haujlwm tsis sib xws. Lawv yog cov cuab yeej tseem ceeb rau cov tuam txhab uas ua haujlwm hauv cov xwm txheej nyuaj vim lawv qhov tseeb, kev hloov pauv tau, thiab kev kub ntxhov siab. Qhov zoo uas lawv muab nyob rau hauv cov nqe lus ntawm kev saib xyuas qhov kub thiab txias feem ntau tshaj cov kev tsis zoo no, txawm hais tias muaj peev xwm ua tau tus nqi thiab kev txwv kev teeb tsa. Tungsten-rhenium thermocouples yuav dhau los ua qhov tseem ceeb tshaj rau kev ua haujlwm thiab kev nyab xeeb ntawm ntau txoj haujlwm vim tias kev lag luam txuas ntxiv thawb cov kev txwv ntawm kev siv thev naus laus zis thiab ua haujlwm hauv qhov chaw hnyav dua. Cov thermocouples no yog ib qho kev xaiv rau txhua tus neeg uas xav tau qhov ntsuas kub ntawm qhov kub thiab txias, txawm tias lawv siv hauv dav hlau, steel ntau lawm, kev tsim khoom semiconductor, lossis lwm daim ntawv thov kub. Vim yog lawv cov khoom tshwj xeeb, lawv tau nce qib ntawm qhov ntsuas kub ntawm cov cuab yeej technology, uas tso cai rau kev ua haujlwm zoo dua thiab ua haujlwm tau zoo txawm tias nyob hauv qhov chaw nyuaj tshaj plaws.
