Thermocouple feem ntau yog muaj li ntawm plaub ntu: thermoelectrode (feem ntau hu ua thermocouple tub ntxhais), lub tshuab ntxig ntxig tub, lub raj tu thiab lub thawv thermocouple hlws ris. Txhawm rau kom ntseeg tau tias ib txwm ua haujlwm ntawm lub thermocouple, cov kev cai hauv qab no tau muab tso rau pem hauv ntej rau cov qauv thermocouple:
1. Lub vuam ntawm qhov ntsuas qhov kawg yuav tsum muaj zog. JJG 351-1996 thermocouple cov ntawv pov thawj cov ntaub ntawv pov thawj pom tseeb tias cov ntawv nyeem yog:" Lub vuam ntawm lub ntsuas qhov kawg ntawm lub thermocouple yuav tsum muaj zog thiab kheej kheej, thiab cov nplaim yuav tsum muaj lubricated, tsis muaj qhov cua ntawm qhov, thiab tsis muaj ntawm slag."
2. Nws yog qhov tsim nyog yuav tsum muaj qhov rwb thaiv tsev zoo ntawm qhov hluav taws xob kub kub. Hlws ris lub thawv specification GB / T 30429-2013" Muaj Thermocouple" qhov yuav tsum tau ua tshwj xeeb: rau cov thermocouples nrog qhov ntev tshaj li 1m, qhov khoom ntawm nws qhov kub tsis xws luag rwb thaiv tsev thiab nws ntev yuav tsum tsis pub tsawg dua 100MΩ.m; rau cov thermocouples nrog qhov ntev ntawm 1m lossis tsawg dua, Nws ib txwm kub rwb thaiv tsev tsis kam yuav tsum tsis pub tsawg dua 100MΩ.
3. Cov kev sib txuas ntawm cov siv davhlau ya nyob twg thiab cov hlau yuav tsum yooj yim thiab ntseeg tau.
4. Thaum siv cov xov xwm phom sij rau cov thermoelectrodes, nws yog qhov tsim nyog yuav tsum xaiv cov kav dej txij nkawm uas tsim nyog txhawm rau cais tawm cov xov xwm phom sij.
5. Lub sijhawm thermal teb yuav tsum tau ua raws li qhov yuav tsum tau ua ntawm cov txheej txheem ntau lawm, feem ntau qhia los ntawm τ, xws li τ0.5, τ, .90.9, thiab lwm yam. Cov. Cov dej ntws ceev ntawm lub cuab yeej yuav tsum yog 0.4 ± 0.05m / s, qhov ntsuas kub pib yuav tsum nyob hauv thaj tsam ntawm 5-45 ℃, thiab theem ntsuas kub yuav tsum yog 40-50 ℃. Thaum lub sijhawm ntsuas, qhov kub hloov pauv ntawm cov dej yuav tsum tsis pub tshaj ± 1% ntawm tus nqi ntsuas kub. Qhov tob tob ntawm qhov ntsuas ntawm tus ntsuas sov siab yog 150 hli lossis tus qauv tsim kev nkag mus tob.

⑪Thermal electrode (cov qauv thermocouple)
Cov thermocouples raug cais raws cov qauv
1. Lub cev ntab tawm (thermocouple Cheebtsam tuaj yeem nqa tawm los ntawm lub raj tu).
2. Nws tsis tuaj yeem rhuav tshem cov thermocouple: Lub thermocouple lub rooj sib txoos ua ke nrog kev tu lub raj, thiab nws nyuaj rau nws tshem tawm los ntawm lub raj tu. Cov thermocouple tsis tuaj yeem rhuav tshem thiab muab faib ua cov khoom muaj tseeb thermocouple thiab armored thermocouple
3. Saj zawg zog cable thermocouples: siv cov thermocouples uas xa tawm los yog thaiv nrog cov inorganic fibers. Lub thawv hlaub tsim cov khoom muaj ib ntu ntawm cov ntaub ntawv hlau txij nkawm ze ntawm lub ntsuas ntsuas.

Thaum cov cuab yeej siv hluav taws xob tsis zoo ua cov ntsuas kub: peb tuaj yeem xaiv qhov kub thiab txias ntawm cov khoom siv xws li ntsuas qhov ntsuas kub rau lub ntsuas kub hauv cheeb tsam, tab sis thaum ntsuas lub cim ntsuas kub tau xa mus, cov ntsuas kub tshaj plaws ntsuas khoom peb siv yog: thermal tsis kam thiab ntsuas sov.
Thermocouple yog ib qho ntawm cov khoom siv ntsuas kub uas tsis tshua pom muaj nyob hauv kev lag luam. Qhov zoo yog:
Txiav ntsuas qhov tseeb. Vim tias cov thermocouple nyob hauv kev sib cuag ncaj qha nrog ntsuas ntsuas, nws tsis cuam tshuam los ntawm nruab nrab nruab nrab.
Txoj kev ntsuas ntau yam. Kev siv cov thermocouples tuaj yeem ntsuas tsis tu ncua ntawm -50 txog +1600 ° C, thiab qee qhov tshwj xeeb thermocouples tuaj yeem ntsuas -269 ° C (xws li kub, hlau, npib tsib xee thiab chromium), nce mus txog +2800 ° C (xws li tungsten-rhenium) )).
③Simple tus qauv thiab ua haujlwm yooj yim. Thermocouples feem ntau yog tsim los ntawm ob hom hlau sib txawv, thiab tsis txwv los ntawm qhov loj me thiab pib me me, thiab muaj lub tes tsho txij nkawm sab nraud, uas yooj yim rau siv.
1. Lub hauv paus ntsiab lus ntawm thermocouple ntsuas kev ntsuas kub
Weld tus neeg xyuas pib lossis semiconductors A thiab B ntawm ob qho khoom sib txawv los ua lub voj kev kaw. Thaum muaj qhov kub ntawm qhov sib txawv ntawm ob qhov txuas ntxiv 1 thiab 2 ntawm cov neeg ua yeeb yam A thiab B, lub zog hluav taws xob muaj nyob nruab nrab ntawm ob, yog li tsim qhov loj thiab me tam sim no hauv lub voj. Qhov tshwm sim no yog hu ua cov nyhuv thermoelectric. Cov thermocouples siv cov nyhuv no ua haujlwm.

Thermocouple nyob rau txoj haujlwm tseem ceeb hauv kev ntsuas kev ntsuas kub. Txhawm rau txhawm rau hloov pauv tau ua haujlwm kub ib puag ncig, muaj ntau hom thermocouples: B hom, S hom, E hom, K hom, R hom, J hom, T hom thiab lwm yam thermoelectrics Nkawg hom. Hauv qhov ntsuas kub ntsuas puag ncig sib txawv, hlov lub thawv xa khoom siv ntau hom thermocouple los xyuas kom muaj kev nyab xeeb ntawm cov khoom siv thiab kev cia siab ntawm cov ntsuas hluav taws xob kis.
Tam sim no, lub thawv ntawv lub thawv roj thermocouple feem ntau siv hauv cov thawv thermocouple hauv lub nruab nrog feem ntau suav nrog cov thawv ntim dej tsis sib xws, pob tawg-pov thawj kev sib tsoo lub thawv, cov ntawv sib txuas ntawm cov hlau tsis sib thooj, cov thawv hlwv yas, lub thawv sib txuas rau cov ntsuas kub sab hauv, thiab imitation imported lub pob hlwv.

Yuav ua li cas xaiv thermocouple lub thawv hlws ris
Cov chaw tsim khoom lossis cov ntawv thov yuav tsum xaiv cov ntawv thermocouple hlws ris thawv raws li cov xwm txheej ib puag ncig ntawm daim ntawv thov thermocouple raws li cov ntsiab cai hauv qab no:
1. Lub thawv dej thaiv kab ke: siv rau hauv cov chaw ntub dej lossis qhib qhov chaw, nws yog cov qauv txheej txheem rau cov dej noo thaum lawv tawm lub hoobkas.
2. tawg-pov thawj kev sib tshuam lub thawv: siv nyob rau hauv qhov chaw tawg thiab qhov chaw tawg, tawg-pov thawj thermocouple Hoobkas txheem teeb tsa.
3. Lub thawv hlwv yas: siv rau hauv cov chaw nrog muaj zog corrosion, nws yog lub Hoobkas qauv teeb tsa ntawm kev tiv thaiv corrosion thermocouple.
4. Lub thawv hlaus tsis xeb hlau: Qhov no yog lub thawv ntim cov thawv ua tau zoo siab nrog lub thawv ua kom pom qhov zoo, feem ntau siv hauv kev tiv thaiv corrosion lossis tawg thiab qhov chaw tawg.
5. Lub thawv txiav ua rau kev sib xyaw ua kom sov kub: siv rau qhov ntsuas kub ntawm lub nruab nrog cua sov qhov hluav taws xob nrog qhov ntsuas kub ntawm qhov kub.
6. Ua kom zoo siab rau hauv lub thawv hlaus: siv thaum kho cov khoom ntawm cov khoom tuaj txawv teb.
