Hom n thermocouples: ruaj khov thiab muaj tseeb hauv cov xwm txheej sib txawv

Nyob rau hauv lub realm ntawm ntsuas kub, muaj cov cuab yeej txhim khu kev qha yog qhov tseem ceeb, tshwj xeeb tshaj yog thaum cuam tshuam nrog ntau hom kev mob ib puag ncig. Hom n Thermocouples tau tshwm sim raws li cov kev daws teeb meem, muab cov khoom ruaj khov thiab qhov tseeb hauv ntau cov ntawv thov.

Hom n Thermoroup yog muaj tsib xee - chromium - silicon thiab npib - silicon - cov hlau nplaum. Qhov no tshwj xeeb ua ke ntawm cov ntaub ntawv muab rau lawv txawv cov khoom uas tau teeb lawv sib nrug ntawm lwm yam thermocouple hom. Ib qho ntawm cov txiaj ntsig tseem ceeb yog lawv txoj kev tawm tsam oxidation thiab corrosion. Hauv cov chaw muaj kev muaj ntau qhov chaw uas muaj cov tshuaj hnyav thiab muaj cov cua noo ntau, cov thermocouples muaj peev xwm tswj hwm lawv txoj kev ncaj ncees. Piv txwv li, hauv cov tshuaj lom neeg ua noj, hom n thermouples tuaj yeem siv los ntsuas qhov kub ntawm cov hlab uas tsis yooj yim los ntawm cov tshuaj hlab caj pas sab hauv.

Cov thermocouces no tseem muaj kev nthuav qhia kev ruaj khov zoo dua sijhawm. Lawv cov khoom thermoelectric nyob twj ywm, txawm tias raug cov kev hloov pauv hloov chaw. Hauv lub hwj chim tiam neeg, qhov twg cov khoom siv mus raws li niaj zaus pib - nce thiab kaw - kom kub hloov, ntaus n thermouples muaj peev xwm muab kev txhim khu kev qha nyeem ntawv. Qhov kev ruaj khov no kom ntseeg tau tias cov neeg ua haujlwm tuaj yeem hais txog kev txiav txim siab raws li cov ntaub ntawv raug, ua kom zoo tshaj plaws ntawm cov khoom siv fais fab tiam.

Qhov tseeb yog lwm cov ntsiab lus tseem ceeb ntawm hom n Thermocouples. Lawv tau tsim los muab cov kev ntsuas kub ntsuas kub nyob hauv qhov kub ntau, feem ntau los ntawm {{0} degree rau 1300 degree. Hauv kev ua lag luam ua khoom noj, qhov twg qhov kev tswj kom kub kub yog qhov uas muaj kev nyab xeeb thiab ua tau zoo, siv N Thermouure, thiab cov chav tub yees txias, thiab cov tshuab tub yees. Txawm hais tias nws yog kom ua rau cov nqaij ntawd ua rau sab hauv qhov kub thiab txias rau hauv qhov txias thiab txias rau cov tub yees uas yog siv tau.

Ntaus N Thermouvles kuj raug nqi - ua tau zoo piv rau qee qhov siab - ua tau thermocouples. Thaum lawv muab cov txiaj ntsig siab - kev ua tau zoo, lawv cov ntaub ntawv ntau lawm thiab cov txheej txheem tsim khoom lag luam ua rau lawv pheej yig. Qhov no ua rau lawv qhov kev xaiv txaus nyiam rau kev lag luam uas xav tau kev txhim kho cov ntsuas kub tab sis muaj cov nyiaj txiag tsis txaus. Me - rau nruab nrab - cov tuam txhab tsim khoom me me tuaj yeem tau txais txiaj ntsig los ntawm kev siv hom n Thermocouples nyob rau hauv lawv cov kab ntau lawm tsis muaj mob ntau dhau.

Txawm li cas los xij, zoo li cov khoom lag luam, hom n thermocouples muaj lawv cov kev txwv. Lawv yuav tsis yog qhov tseeb yog qee qhov kim dua noblem - hlau - raws likrooob hauv cov ntawv thov siab heev - qhov kub thiab txias dua 1300 degree. Tsis tas li, lawv tuaj yeem cuam tshuam los ntawm cov sib nqus ntawm thaj chaw hauv qee thaj chaw, uas yuav xav tau kev tiv thaiv ntxiv lossis ua tib zoo npaj.
