Tungsten-rhenium thermoco thermoounles: kev ua tau zoo daws teeb meem rau huab cua sov heev

Tungsten-rhenium thermocouples yog cov kev ua tau zoo ntsuas kom ua haujlwm hauv kev xaiv huab cua sov, ua rau lawv cov kev xaiv tsim qauv thermoco. Cov thermocouples muaj peev xwm ntawm kev ntsuas kub ntsuas txog li ntawm 2200 ° F), xws li cov khoom siv hluav taws xob feem ntau, kev tshawb nrhiav hlau, thiab cov ntaub ntawv kev tshawb fawb dav hlau, thiab cov ntaub ntawv kev tshawb fawb ua haujlwm, thiab cov ntaub ntawv kev tshawb fawb ua haujlwm, thiab cov ntaub ntawv kev tshawb fawb dav dav, thiab cov ntaub ntawv kev tshawb fawb dav dav, thiab cov ntaub ntawv kev tshawb fawb dav hlau, thiab cov ntaub ntawv kev tshawb fawb dav dav, thiab cov ntaub ntawv kev tshawb fawb dav hlau, thiab cov ntaub ntawv kev tshawb fawb dav hlau, thiab cov ntaub ntawv kev tshawb fawb ua haujlwm, thiab cov ntaub ntawv kev tshawb fawb dav dav, thiab cov ntaub ntawv kev tshawb fawb dav hlau, thiab cov ntaub ntawv kev tshawb fawb ua haujlwm, thiab cov ntaub ntawv kev tshawb fawb dav hlau, thiab cov ntaub ntawv kev tshawb fawb dav dav, thiab cov ntaub ntawv kev tshawb fawb dav hlau, thiab cov ntaub ntawv kev tshawb fawb dav dav, thiab cov ntaub ntawv kev tshawb fawb dav hlau, thiab cov ntaub ntawv kev tshawb fawb txog kev ua haujlwm, thiab cov ntaub ntawv kev tshawb fawb txog kev ua haujlwm, thiab cov khoom siv kev tshawb fawb txog kev paub. Lawv qhov tshwj xeeb depability thiab qhov tseeb nyob rau hauv cov dej siab ib puag ncig tau tsim lawv ua lub cuab tam tseem ceeb rau kev lag luam uas xav tau huab cua sov. Los ntawm kev sib txuas cov khoom tshwj xeeb ntawm tungsten thiab rhenium, cov thermocoples xa kev ua tau zoo nyob rau hauv lub ntsej muag ntawm kev kub ntxhov thiab ib puag ncig cua sov thiab hnyav.

Kev tsim kho ntawm tungsten-rhenium thermocouples yog qhov tseem ceeb hauv lawv lub peev xwm tiv thaiv huab kub. Lawv feem ntau yog ua los ntawm alloys ntawm tungsten thiab ntau hom feem ntau yog hom c (tungsten {}}}} {% rhenium). Cov alloys tau xaiv rau lawv cov ntsiab lus siab, zoo heev thermal stability, thiab ua rau oxidation ntawm ntug kev kub siab. Thermocouples feem ntau yog tsev nyob rau hauv kev tiv thaiv sheaths ua los ntawm cov ntaub ntawv xws li molybdenum lossis tantalum, uas muab kev cuam tshuam ntxiv rau cua sov thiab xeb. Qhov kev tsim kho zoo no ua kom nruj uas cov tungsten-rhenium thermocoloto tuaj yeem tswj hwm lawv cov kev ncaj ncees thiab cov qauv kev cai txawm nyob hauv cov xwm txheej tshaj plaws.

Ib qho ntawm cov khoom seem ntawm tungsten-rhenium thermocouples yog lawv lub peev xwm xa cov kev ntsuas uas muaj lwm lub sensors yuav txwv lossis swb. Hauv kev lag luam hlau ntxiv, piv txwv li no, cov thermouvroures no tau siv los saib ntsuas kub hauv cov khoom siv ua haujlwm siab thiab superalloys. Lawv lub peev xwm tiv thaiv kev tiv thaiv hnyav heev, uas yog qhov tseem ceeb rau kev ua tiav cov khoom xav tau. Hauv kev siv Aerospace, tungsten-rhenium thermocouples yog siv los ntsuas kev ua yeeb yam ntawm cov pob zeb hluav taws xob thiab lwm cov ntaub ntawv txhim khu kev qha yog qhov tseem ceeb rau kev nyab xeeb. Ib yam li ntawd, hauv cov ntaub ntawv kev tshawb fawb siab, cov thermocouples tau ua haujlwm los kawm cov cwj pwm ntawm ultra-siab kub, muab cov peev txheej muaj txiaj ntsig zoo rau kev txhim kho ntawm cov thev naus laus zis tshiab.

Txawm hais tias lawv tau kev ua tau zoo, tungsten-rhenium thermoco thermocouples muaj qee qhov kev txwv, xws li kev ua kom pom kev ntawm oxidizing ib puag ncig ntawm qhov kub. Txawm li cas los xij, cov kev sib tw no tuaj yeem raug ntsuas los ntawm kev siv cov cua tiv thaiv, xws li cov pa roj av lossis lub tshuab nqus tsev, uas tiv thaiv kev ua haujlwm ntawm lub neej ntawm thermocouples. Ib qho ntxiv, kev ntsuas kom raug thiab txij nkawm yog qhov tseem ceeb los xyuas kom muaj kev ntev thiab kev ntseeg tau. Los ntawm kev daws cov kev txiav txim siab no, kev lag luam tuaj yeem rub lub peev xwm ntawm tungsten-rhenium thermocouples kom ua tiav qhov kub thiab txias kev tswj kom sov.

Cov neeg muaj txiaj ntsig thiab cov txiaj ntsig ntawm tungsten-rhenium thermocouples ua rau lawv tsis muaj qhov tseem ceeb rau kev lag luam ntawm kev txiav cov thev naus laus zis. Lawv lub peev xwm los muab qhov ntsuas kom raug thiab txhim khu Txawm hais tias nyob hauv cov hlau ua kom sov, lossis cov ntaub ntawv tshawb nrhiav tshuab hluav taws xob muab cov khoom siv nyuaj, ua rau lawv muaj lub hauv paus kev nyuaj tshaj plaws, ua rau muaj kev ntsuas cov ntsiab lus ntau tshaj plaws.
