Lub ntsiab lus thiab kev xaiv ntawm Thermocouple Them Hlau

1. Vim li cas siv thermocouples los them nyiaj rau cov xov hlau?

Vim tias thermocoples tuaj yeem ua tiav kev ntsuas kub, vim li cas siv cov xov hlau

Cia peb mus saib cov ntaub ntawv thov ntawm kev ntsuas.

Feem ntau hais lus, rau qhov yooj yim ntawm kev soj ntsuam thiab ntsuas kub ntawm kev ntsuas ntsuas yuav luag tas li, uas yooj yim heev

Muab qhov chaw ua haujlwm ntawm ib qho kev ncua deb ntawm qhov ntsuas kub tiag tiag. Ntawm qhov kev ncua deb no, qhov xwm txheej feem ntau nyuaj

Piv txwv li, dhau los ntawm cov peev txheej fais fab, tej zaum yuav muaj hluav taws xob cuam tshuam hluav taws xob, uas feem ntau yuav nquag raug rau sab nraud. Kev siv ntawm cov kav hlau thicalocouple tuaj yeem ua rau kev ntsuas tsis yog, tawg yooj yim thaum siv cov teeb meem, thiab cov teeb meem hloov pauv ntau. Tsis tas li ntawd, cov ntaub ntawv ntawm Thermocouple xov hlau feem ntau kim, thiab tus nqi kuj tseem siab heev rau kev siv ntev. Cov no yog txhua yam laj thawj rau kev siv cov xov tooj hluav taws.

Hauv cov ntsiab lus xaus, siv cov xov hlau tau muaj cov txiaj ntsig hauv qab no

1) Txhim kho lub cev thiab cov kws kho tshuab ntawm cov ntsuas kub ntsuas ntsuas cua ntawm thermoco. Siv ntau cov xov hlau ntau lossis cov hlau me uas tau them cov xov hluav taws xob tuaj yeem txhim kho cov hluav taws xob, thiab tseem kho cov hlau tsis tawm lossis thaiv kev cuam tshuam

2) Txo cov nqi ntsuas ntsuas. Thaum qhov kev ncua deb ntawm thermocouples thiab ntsuas cov cuab yeej ntev, siv cov xov hlau ntev, tshwj xeeb yog siv cov khoom siv hlau thermocofle ntau.

2. Kev faib tawm ntawm Thermoculeple nyiaj them

Thermocouple them nyiaj tuaj yeem faib ua ob pawg:

1) Txuas Them Ntsuas Txuas Txuas

Kev them nyiaj ntxiv, tseem hu ua cov hmoov txhuas ncua, muaj cov khoom siv thermocoupric, piv txwv li, "

2) Nyiaj Txiag Ntaus Hlau

Kev Them Nyiaj Ua Nyiaj Txiag, tseem hu ua Cov Nyiaj Txiag Ntaus Cov Khoom Siv Hluav Taws Xob uas yog qhov sib txawv ntawm cov khoom siv thermocoelle, tab sis qib "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" C "C" c " Txoj Cai, piv txwv li, "KC" cov nqi hyperbolic cosine. Cov kav hlau alloy sib txawv yog qhov haum rau thermocouples nrog tib tus lej ntsuas thiab tuaj yeem txawv los ntawm cov tsiaj ntawv.

3. Qhov tseeb txoj kev rau kev xaiv cov xov thermocouple

Txoj Kev Sib Tham ntawm cov hlau roj teeb yuav tsum muaj ua kom sib haum nrog cov thermocouple siv. Piv txwv li, K-hom thermocouples yuav tsum siv K-hom Thermocouple them xov hlau.

Thaum xaiv raws li qhov ntsuas kub ntawm kev siv cov kev siv, cov ntsuas kub ua haujlwm tau tsawg, feem ntau muab faib ua ob hom: {} degree thiab {1}} degree. Tus nqi ntawm 0-100 degree yog qis dua thiab tuaj yeem xaiv raws li cov kev xav tau tiag tiag.

Thaum muaj ntau cov txiaj ntsig ntawm kev cuam tshuam rau ntawm lub xaib, cov xaim hluav taws xob nrog cov khoom tiv thaiv muaj zog tuaj yeem xaiv tau.

Thaum muaj ntau qhov ntsuas kub ntsuas tib lub sijhawm, cov kab ke nrog ntau cov pawg ntawm cov xov tooj tau xaiv tau.

4. Kev ceev faj rau kev siv cov xov hlau

1) Kev xaiv ntawm cov xaim them nyiaj yuav tsum yog ua raws li cov thermocouple siv thiab qhov kev xaiv yog thaum siv thaum siv thaum siv thaum siv thaum siv thaum siv. Piv txwv li, K hom txawm lossis K Hom txawm tias them nyiaj yuav yuav tsum tau xaiv.

2) Ob tus neeg sib cuag ntawm kev sib cuag sib txuas thiab thermocouple davhlau ya nyob twg yuav tsum tau ze li sai tau kom ntseeg tau tias qhov kub ntawm ob qho kev sib cuag. Qhov sib txuas nrog lub ntsuas ntsuas yuav tsum khaws cia tib qhov kub kom ntau li ntau tau los tiv thaiv cov chaw nyob ntawm lub ntsuas vaj huam sib luag los ntawm kev sib cuag nrog tus kiv cua.

3) Vim tias lub teeb liab qis ntawm qhov ntev ntawm microvolts, thaum siv rau qhov ntsuas hluav taws xob txuas ntxiv, ntsuas hluav taws xob tsis raug thiab ntsuas kom sov, thiab muaj mob hnyav. Feem ntau, nws yog qhov zoo rau siv thermocouples los tswj cov hlau ntev tsis pub dhau 15 metres, nws raug nquahu kom siv cov cim ntsuas kub kom xa cov paib. Cov nqi kub hloov pauv cov nqi muaj peev xwm sib raug rau qhov kub thiab txias rau hauv tam sim no thiab hloov suab nrov tsis kam.

4) Cov xaim hluav taws xob ntawm cov xov hlau them yuav tsum tau tso kom deb ntawm cov kab hluav taws xob thiab cov suab nrov. Hauv cov chaw tsis muaj kev xaiv tsis tau, sim siv txoj kev hla kev thiab tsis txhob sib piv.

5) Cov ntawm cov xov xwm them nyiaj kho mob tuaj yeem siv los txhim kho kev tawm tsam kev cuam tshuam ntawm thermocouple txuas xov hlau. Thaum muaj ntau lub sijhawm ntawm lub suab nrov ntawm qhov chaw, cov nyhuv yog qhov zoo dua. Txawm li cas los xij, daim thaiv npog txheej yuav tsum tau ua kom nruj. Daim thaiv npog txheej tsis tsuas yog ua tsis tiav los muab kev tiv thaiv, tab sis kuj tseem ua suab nrov
