Kev thov txuas ntxiv ntawm Thermocouple them xaim

Vim li cas siv cov xov tooj hluav taws?

Vim tias thaum siv qhov ntsuas kub rau kev ntsuas kub, ntsuas qhov ntsuas kub uas tau qhia kom muaj qhov tseeb, uas yuav cuam tshuam qhov tseeb ntawm kev ntsuas kub. Txawm li cas los xij, nyob rau hauv cov chaw siv rau hauv kev siv, cov thermocouple reflection kawg, thiab cov thermocouple referts tsis tuaj yeem ruaj khov vim hais tias qhov cuam tshuam ntawm qhov chaw kub. Yog li ntawd, nws yog ib qho yuav tsum tau txav cov thermocouple referend kawg mus rau qhov chaw nyob nrog lub qhov chaw nyob ruaj khov; Cov hlau roj teeb tau ua los ntawm cov khoom siv hlau uas yog thermocoelple nws tau txuas nrog rau hauv cov khoom siv cua sov uas muaj thiab tsis muaj txiaj ntsig). Nws tuaj yeem txuas txoj haujlwm ntawm kev ntsuas thermocouple hauv qhov ntsuas kub lossis ua haujlwm txuas nrog cov hlau sib txuas ntawm cov khoom siv thermocouple thiab cov khoom siv hluav taws xob (xws li hluav taws xob notentiometers). Yog li, thaum siv thermocouples, cov xov hlau yuav tsum muaj kev sib txuas. Tab sis nws tsis tuaj yeem tshem tawm cov cawv ntawm tsis-xoom siv hluav taws xob, yog li cov siv ntsuas kub yuav tsum tau kho rau {4}} degree thaum siv.

Thaum siv cov xov hluav taws xob ntxiv, cov ntsiab lus hauv qab no yuav tsum tau sau tseg:

1. Ntau cov xov hluav taws xob tsuas yog siv nrog cov qauv thermocoile ntawm ntau yam thermocoples thiab cov roj cua sov siv nyob rau hauv qhov chaw teev dej khov (xws li {{1} degree).

Thaum txuas cov xaim hluav taws xob rau lub ntsuas ntsuas thermocouple, ob khub ntawm cov ntsiab lus sib txuas yuav tsum yog tib tus ntsuas kub thiab qhov zoo thiab tsis zoo thiab tsis muaj qhov txuas tsis raug. Cov xaim hluav taws xob yog sib npaug rau qhov ntsuas kub tsis pub dhau ib qho kub thiab txias ({} degree) Yog li ntawd, thaum txuas nrog cov thermocouple, qhov zoo electrode ntawm cov xaim hluav taws xob yuav tsum txuas nrog qhov tsis zoo electrode ntawm lub thermocouple. Yog tias polarity tau thim rov qab, tsis yog them rau cov xaim hluav taws xob poob nws txoj haujlwm, tab sis nws tseem yuav ua rau qee lub zog cua sov, ua rau qhov ntsuas kub los txo qis.

3. Qhov kub ntawm qhov sib txuas ntawm cov xaim hluav taws xob thiab thermocouple yuav tsis tshaj qhov ntsuas kub ntawm qhov ntsuas kub.

4. Txoj kab uas hla ntawm cov xaim hluav taws xob yuav tsum tau raug xaiv raws li cov cai sib txawv ntawm cov khoom siv sib txawv. Piv txwv li, cov hlau hluav taws xob txuas nrog lub zog sib txuas tuaj yeem raug xaiv nrog cov kav hlau tsis kam, yog li tsis cuam tshuam rau lub ntsuas hluav taws xob tiv thaiv tus nqi.

5. Rau cov thermocouples nrog cov xov ntev dua, ntau yam thiab tuab them cov xov hlau tuaj yeem siv tau yooj yim thiab tso pw.

Cov xov cov xov hlau yuav tsum muab faib ua ob hom raws li cov khoom siv hlau tseem ceeb: txuas yam khoom thiab nyiaj ntau hom

Kev them nyiaj ntxiv rau cov xov hluav taws xob: NX (Nickel Chromium silicon npib tsib xee 45), jxel Npib Tsib Nrab 45), TX (Tooj Tooj Liab Nickel 45).

Nyiaj Txiag Ntaus Xov Tooj: suav nrog sc thiab rc (tooj liab tooj liab nickel}. 6), NC (hlau tooj liab npib), thiab lwm yam.

Sijhawm rau kev siv txuas ntxiv lossis them nyiaj hom nyiaj:

Hom txuas ntxiv: Thaum ib puag ncig qhov chaw txias kawg ntawm cov xaim hluav taws xob muaj ntau dua 1} 0 degrees, nyob rau hauv kev ntsuas them nyiaj yog xaiv, tab sis tus nqi yog kim.

Nyiaj Txiag Ntaus: Kev lag luam nyiaj pheej yig, tab sis qhov txias txias yuav tsum yog nyob rau hauv qhov chaw nyob ruaj khov.

Cov yam ntxwv uas them cov xov hlau yuav tsum muaj:

1. Cov yam ntxwv thermoeltric, cov hluav taws xob zoo rwb thaiv tsev, thiab lub neej ntev.

2. Mos muag, nrog qhov zoo dabtsi yog khoov kev ua tau zoo thiab siv tau yooj yim.

3. Cov khoom siv txheej ua kom ruaj khov thiab txhim khu kev qha, nrog qee yam kub tsis kam thiab txias kuj.
