Kev xaiv kom raug ntawm thermocouples thiab cov laj thawj rau kev ntsuas tsis yog

Thermocouples, raws li ib qho ntawm cov ntsuas kub tseem ceeb hauv kev ntsuas cov tshuab hluav taws xob, tau ua rau muaj kev sib koom tes kub hauv ntau yam kev lag luam. Nws yog dav siv nyob rau hauv lub teb ntawm kev tswj qhov kub thiab txias hauv ntau yam kev lag luam, ntsuas qhov tseeb, ntsuas dav ntau yam, thiab yooj yim txij nkawm. Txawm li cas los xij, nws yog qhov meej meej vim tias thermocouple nws tus kheej muaj qhov yooj yim ntawm lub sij hawm xaiv tau ntau zaus thiab kev puas tsuaj rau cov thermocouple thaum siv. Ib qho ntxiv, kev ntsuas yuam kev tshwm sim los ntawm cov teeb meem ntsuas kub xws li kev teeb meem kub, thiab thermal imporable thiab thermal imporable thiab bermal poob rau cov neeg siv khoom tiag tiag. Ua ntej ua ntej nce kev nce ntawm kev nyab xeeb ntawm kev nyab xeeb, kev ntsuas lub neej dav dav, thiab cov qauv ntsuas cua sov, thiab ntsuas kub ntawm cov qauv ntsuas cua sov. Ntawm no lub hauv paus pib ntawm kev xaiv thiab cov tswv yim ntawm kev ntsuas kub thiab ntsuas qhov ntsuas kub ntawm qhov sib txawv ntawm qhov tob tob ntawm qhov tob tob ntawm thermocouples. Nyob rau tib lub sijhawm, kev tsom xam tau ua rau kev ntsuas tsis yog los ntawm kev them nyiaj kub, thermal impradation, thiab thermocouple tsis zoo thaum siv cov kev daws teeb meem, thiab cov kev daws teeb meem tau muab. Kuv vam tias nws tuaj yeem pab tau rau kev ntsuas cov ntsuas kub thiab txias thiab ntsuas kub ntev ntsuas ntawm thermocouples.
1. Xaiv los ntawm thermocouples
Thermocouples tau siv dav lawm vim yog lawv txoj haujlwm xaiv yooj yim thiab kev nyab xeeb yog them nyiaj rau theem thiab lub siab ua haujlwm theem ntawm cov khoom siv tes tsho. Txawm li cas los xij, kev yoog tau, ntsuas kub ntau yam, thiab kev nqus ntxig ntawm cov thermocouples yooj yim tau yooj yim tsis quav ntsej, uas cuam tshuam rau qhov ntsuas kub thiab txias.
1.1 Xaiv cov xov tooj thermocouple
Kev xaiv ntawm cov xov tooj thermocouple index Feem ntau, raws li qhov ntsuas kub ntawm sib txawv ntawm cov thermocouts rau hauv peb pawg, peb ntxhib siab kub, thiab kub siab ntsuas thermocoecles. Hauv qab no yog kev tsom xam thiab kev sib tham txog yuav ua li cas xaiv thermocouples rau cov ntsuas kub no.
1.1.1 Xaiv cov nruab nrab thiab tsawg kub thermoco
Yog tias siv rau cov ntsuas kub tsawg ({{{{1} degree ~ {{+350}}}} degree thermocouple tuaj yeem raug xaiv. Rau nruab nrab thiab qis-ntsuas ntsuas ({-40 degree ~ {{}} degree thermocouple tuaj yeem raug xaiv. Txawm li cas los xij, vim qhov tseeb tias cov khoom siv hluav taws xob zoo ntawm TJ nplai ntawm kev tsim khoom thiab siv cov khoom ntshiab thiab siv tsis tau rau kev ntsuas kub hauv qhov chaw oxidizing. Nws raug nquahu kom siv e-teev thermocouple rau kev ntsuas kub hauv ib puag ncig oxidizing. Qhov ntsuas E-Index Thermocouple tsis yog hais txog qhov ntsuas kub ntawm J-Performance qhov muaj peev xwm tawm, tab sis kuj tseem muaj oxidation loj, thiab kuj zoo dua oxidation tsis kam tshaj li ntawm cov lus qhia ntawv TJ. Nws tuaj yeem siv rau hauv oxidizing thiab inert roj ib puag ncig, tab sis tsis tuaj yeem siv ncaj qha hauv cov leej faj thiab txo cov roj ib puag ncig ntawm ib puag ncig dej kub. Qhov no yuav ua rau muaj qhov yuam kev tseem ceeb nyob rau hauv lub thermoelectric muaj peev xwm sib txig ntawm e-index thermocouple.
1.1.2 Xaiv cov nruab nrab thiab ntsuas kub kub
K-Degree Thermocouple yog ib dav siv tsawg tus nqi hlau thermocouple, tsuas yog siv rau kev ntsuas kub hauv nruab nrab thiab} degree ~ {{3} degree). Ntawm lawv, K-Index Thermocouples nyob ib qho kev ua lag luam tsis muaj peev xwm ua rau lawv cov peev xwm zoo, muaj kev sib luag loj, muaj txiaj ntsig oxidation tsis kam, thiab tus nqi qis. Tus N-Performance Index Thermocouple yog ib tug tshiab thoob ntiaj teb thermocoupric, uas yog qhov tsis txaus ntseeg ntawm Nickel qhov kev txiav txim siab ntawm Nickel Alloy ntawm 300 degree thiab 500 degree thiab 500 degree thiab 500 degree thiab 500 degree thiab 500 degree thiab 500 degree thiab 500 degree thiab 500 degree thiab 500 degree thiab 500 degree; Lub thermal hluav taws xob muaj peev xwm tsis muaj peev xwm tshwm sim los ntawm kev nyiam oxidation ntawm Nickel chromium alloy nyob ib ncig ntawm 800 degree. Nws qhov kev ua tau zoo tshaj plaws yog zoo dua rau ntawm K-Performance index lub zog, ua rau nws cog lus thermocouple rau kev txhim kho. Txawm li cas los xij, ib qho kev tsis txaus ntseeg ntawm N-degree thermocoear ua yuam kev hauv qhov kub tsawg ({} degree ~ 400 degree) thiab nyuaj rau cov khoom siv.
1.1.3 Xaiv cov ntsuas kub ntawm cov cua sov
S R. Lub b-qib thermocoupleks boilocouple vim tias nws cov hluav taws xob zoo thiab cov platinum rhodium alloy. Nws yog ib thermocrouple haum rau kev ntsuas hauv cov chaw kub-(800 degree ~ 1600 degree). Cov kev pom zoo ntev siv kub siv rau s thiab r co nplai siv txias rau b nplai ntev ntev rau bitai thermocouples yog (800 degree ~ 1600 degree). Vim tias lawv qhov ntsuas kub zoo tshaj plaws, ntsuas qhov ntsuas qhov dav ntau dua li ntawm 1000 degree, xws li metallurgy, iav, ceramics, thiab lwm yam kev lag luam. Cov tsis muaj peev xwm suav nrog cov peev txheej qes, qis dua cov khoom siv kub ntawm cov khoom siv qias neeg, thiab cov khoom muaj nuj nqis zoo, ua rau muaj peev xwm loj. Tab sis txhua yam, cov khoom siv hlau ua kom muaj txiaj ntsig tseem yog lub zog tseem ceeb hauv kev ntsuas kub nyob hauv cov chaw kub-ntsuas. Nrog kev txhim kho txuas ntxiv ntawm thermocouple ntau lawm tshuab hluav taws xob, lawv tuaj yeem tiv thaiv cov xov hluav taws xob hluav taws xob ntawm cov khoom kub thiab txhim kho kev pabcuam lub neej.
