Qee qhov kev paub txog kev paub txog thermoco

Lub ntsiab tseem ceeb cuam tshuam rau kev ruaj ntseg ntawm thermocouples yog:

(l) Thermoelectric cov hluav taws xob caij nyoog dhau oxidation thaum siv, feem ntau xaiv oxidation thiab volatilization ntawm qee yam.
(2) Kev ntxhov siab ntawm deformation tshwm sim los ntawm lub zog sab nraud ua rau ntawm lub thermoelectric electrode.
(3) thermoelectric kev siv hluav taws xob muaj kev paub cov noob qoob loo ntawm cov kub.
(4) kev paug thiab corrosion ntawm thermoelectric siv.

Vim li cas cov thermocouple inffeter Circuit Court yuav tsum muaj kev sib txuas txias txias kub?
Teb: Vim tias thaum ntsuas kub nrog lub thermocouple, nws yog ib txwm yog qhov xaus txias kom nyob tas mus li, tab sis qhov no nyuaj rau kev ua tiav hauv kev lag luam ntau lawm. Yog li ntawd, nws yuav tsum tau hais tias lub tswv yim circuit ntawm lub transmitter muaj txoj haujlwm ntawm "tus nqi txias kawg li cas". Uas yog hais, thaum cov zis ntawm qhov kub ntawm lub thermocouple hloov nrog qhov kub ntawm qhov txias txias, thiab qhov ntau ntawm kev hloov pauv yuav tsum muaj sib npaug thiab cov kev taw qhia rov qab. Nyob rau hauv txoj kev no, ntsuas yuam kev tshwm sim los ntawm kev hloov nyob rau hauv txias xaus kub tuaj yeem them tau tib yam rau.

Vim li cas cov xaim xaim siv rau kev ntsuas kub ntawm qhov chaw?
Teb: Kev siv cov xov tooj ntawm cov hluav taws xob tsis tsuas yog txav qhov kawg ntawm qhov chaw sov thiab kub thiab txias rau cov khoom siv uas kim heev nrog kev ua haujlwm ruaj khov; Kev siv cov xov hlau them nyiaj kuj tau txhawb kev teeb tsa thiab kab pw; Hloov cov thermoelectric hluav taws xob nrog cov hlau roj teeb nrog cov haujlwm thicker thermer thiab ntau dua kev ua haujlwm ntawm kev tswj chev zaub thiab kev tswj qhov ntsuas kub.

Dab tsi yog tus qauv ntawm kev them nyiaj xaim xaim rau feem ntau siv thermocouples?
Teb: Qauv thiab cov npe ntawm feem ntau siv them nyiaj rau thermocouple: cov roj teeb hluav taws xob tau muab faib rau cov khoom siv hauv KC, KX, EX, JX, TX.

(1) Thawj tus tsiaj ntawv ntawm cov qauv sib raug rau qhov ntsuas ntsuas ntawm qhov thermocouple.

(2) tsab ntawv "X" sawv cev rau kev them nqi hluav taws xob txuas ntxiv (hom).

(3) Tsab ntawv "C" sawv cev rau cov hlau roj teeb (hom).
Nco tseg: Sc Hom Compassating cov xov hlau tuaj yeem nruab nrog R-ntaus cov thermocouples.

Dab tsi yuav tsum tau sau tseg thaum siv thermocouple nyiaj them?

Teb: (1) Cov hlau them yuav tsum sib phim nrog tus qauv sib xws ntawm thermocouple, thiab cov qauv thermoelle, thiab cov qauv ntawm thermoelectric yuav tsum yog tib yam nyob rau hauv thaj tsam ntawm {1}} degree.
(2) Thaum sib txuas them cov xov hlau thiab cov twj paj nruag zoo thiab tsis muaj qhov zoo thiab tsis muaj ob lub khub ntawm cov ntsiab lus sib txuas yuav tsum yog qhov kub tib yam.
(3) qhov ntsuas kub ntawm qhov sib txuas ntawm cov xaim hluav taws xob ntawm cov xaim hluav taws xob thiab thermocouple yuav tsis tshaj qhov ntsuas kub uas tau sau tseg rau kev siv.
(4) Txoj kab uas hla ntawm cov hlau roj yuav tsum tau raug xaiv raws li cov kev xav tau ntawm cov khoom siv sib txawv.

Dab tsi yog cov feem ntau siv thermocouple cua txias kev yos taws kub qhov kub thiab txias txoj kev?
Teb: Muaj tsib txoj hauv kev: txias xaus kev kho tus qauv kub tas li, ntsuas kev hloov kho cov qauv, cov qauv hlau.
