Hom thiab kev ua haujlwm ntawm cov xov tooj thermocouple?

Nrog kev loj hlob sai ntawm kev lag luam, kev siv thermocorochples hauv kev tsim khoom tau dhau los ua ntau zuj zus. Thermocoon tau dhau los ua ib qho kev ntsuas kub feem ntau yog xws li ntsuas siab ntsuas qhov tseeb, ntsuas dav, thiab cov ntawv thov yooj yim. Peb tau tshawb thiab soj ntsuam cov khoom lag luam los ntawm ntau channel, muab ntau txoj kev paub txog kev lag luam dav rau ntau yam Netizens.
Tom ntej no, cia kuv qhia cov hom thiab cuam tshuam ntawm Thermocouple them xov hlau?
1, vim li cas siv cov xov tooj hluav taws?
Nws yog ib qho tsim nyog los tswj lub zog kub ruaj khov ntawm qhov siv kawg ntawm qhov kawg ntawm thermocouple thaum siv nws rau ntsuas kub. Txwv tsis pub, ntsuas kev ua yuam kev qhia lub caij ntsuas kub yuav yog qhov tseem ceeb tshaj plaws, uas yuav cuam tshuam qhov tseeb ntawm qhov ntsuas kub. Txawm li cas los xij, nyob rau hauv cov ntawv thov ntawm cov xaib ntawm lub xaib, qhov kawg ntawm Thermocouple feem ntau nyob ze qhov ntsuas kub uas tsis tuaj yeem ruaj khov vim hais tias muaj kev cuam tshuam nrog cua sov. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum txav cov ntaub ntawv kawg ntawm thermocouple rau qhov chaw nyob nrog lub qhov chaw nrog lub qhov kub khov khov; Cov hlau roj teeb tau ua los ntawm cov khoom siv hlau uas yog cov khoom siv thermocoelple (feem ntau 0-100 degree), thiab yog ua los ntawm cov khoom siv hluav taws xob muaj pheej yig. Nws tuaj yeem txuas cov nyhuv ntawm thermocouple hauv qhov ntsuas kub lossis ua haujlwm txuas nrog cov hlau sib txuas ntawm cov thermocouple thiab cov khoom siv hluav taws xob (xws li hluav taws xob notentiometers). Yog li, thermocows yuav tsum tau txuas nrog them cov xov hlau thaum siv. Tab sis nws tsis tuaj yeem tshem tawm cov cawv ntawm tsis-xoom siv hluav taws xob siv, yog li hauv daim ntawv thov, qhov ntsuas kub yuav tsum tau kho rau {4}} degree.

2, nws yog ib qho tsim nyog los them sai sai rau cov ntsiab lus hauv qab no thaum siv cov xov tooj hluav taws xob:

1. Muaj ntau cov xov hlau tsuas yog siv tau nrog cov xov tooj cua sov uas siv rau ntau qhov ntsuas hluav taws xob tsis pub dhau cov ntsuas kub li qub (xws li 0-100 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 thermocouple tsis pub dhau ib qho kub thiab txias ({} Yog li ntawd, thaum txuas nrog cov thermocouple, tus ncej zoo ntawm cov hlau roj teeb yuav tsum txuas nrog tus ncej tsis zoo ntawm cov thermocouple. Yog tias cov polarity tau thim rov qab, tsis tsuas yog nws yuav plam qee qhov kev siv hluav taws xob ntawm lub thermocouple, ua rau lub ntsuas kub los txo qis.

3. Qhov kub ntawm cov xaim hluav taws xob thiab cov kev sib tshuam thermocouple yuav tsis tshaj qhov ntsuas kub kom raug rau kev siv tsis tu ncua.

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.

3, Cov nqi them nyiaj yuav tsum tau muab faib ua ob hom raws cov tub ntxhais sib txawv ntawm cov khoom lag luam: Hom Kev Txuas Ntxiv thiab Them Nyiaj

Txuas ntxiv them xov tooj: NX (Nickel Chromium Silicon Npib Li 10 Nickel Nickel 45), Txaj Hlau Tooj 45), Txiv Neej (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.

4, cov cib fim rau kev siv txuas ntxiv lossis them nyiaj hom nyiaj:

Hom Txuas Ntxiv:

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

Kev Them Nyiaj Hom: Kev lag luam pheej yig, tab sis qhov txias txias yuav tsum muaj nyob hauv qhov chaw nyob ruaj khov.

5, Cov yam ntxwv tsim nyog ntawm cov xov hluav taws xob yog:

1. Lub zog ruaj khov rau cov yam ntxwv, cov hluav taws xob zoo hluav taws xob muaj nuj nqi, thiab lub neej ntev.

2. Mos thiab ntau yam, nrog kev ua haujlwm zoo thiab siv tau yooj yim.

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