Yuav ua li cas xaiv cov thermocouples kom raug

Kev xaiv ntawm cov thermocouples yuav tsum ua raws li kev xav tau ntawm qhov kub thiab txias, qhov xav tau qhov tseeb, qhov chaw ua haujlwm, kev ua haujlwm ntawm cov khoom ntsuas, lub sijhawm teb, thiab cov txiaj ntsig kev lag luam.
1. Kev xaiv qhov ntsuas qhov tseeb thiab ntsuas qhov ntsuas kub
Thaum ua haujlwm kub ntawm 1300 ~ 1800 degree thiab qhov raug siab yuav tsum tau, B-hom thermocouples feem ntau xaiv; Tsawg precision yog yuav tsum tau, thiab cov cua tso cai rau siv tungsten rhenium thermoelectric cov ntaub ntawv
Qee zaus, tungsten rhenium thermocouples feem ntau yog siv rau qhov kub siab tshaj 1800 degree; Kev siv qhov kub ntawm 1000 ~ 1300 degree yuav tsum muaj qhov raug siab thiab tuaj yeem ua tiav nrog S-hom thermocouples thiab N-hom thermocouples; K-hom thermocouples feem ntau yog siv hauv qab 1000 degree
Rau N-hom thermocouples, E-hom thermocouples feem ntau yog siv rau kub hauv qab 400 degree; Ntawm 250 degree thiab ntsuas kub tsis zoo, T-hom thermocouples feem ntau yog siv. Ntawm qhov kub thiab txias, T-hom thermocouples ruaj khov thiab muaj qhov tseeb.
2. Kev xaiv ntawm kev siv huab cua
S-hom, B-hom, thiab K-hom thermocouples yog tsim rau siv nyob rau hauv muaj zog oxidation thiab tsis muaj zog txo cua sov, thaum J-hom thiab T-hom thermocouples yog haum rau tsis muaj zog oxidation thiab txo cua sov. Yog tias siv lub raj tiv thaiv nrog airtightness zoo, qhov yuav tsum tau ua rau huab cua tsis nruj heev.
3. Kev xaiv ntawm durability thiab thermal teb
Thermocouples nrog cov hlau loj diameters muaj cov kav ntev, tab sis lawv cov lus teb qeeb dua. Rau cov thermocouples nrog lub peev xwm thermal loj, lawv cov lus teb qeeb dua. Thaum ntsuas kub nrog cov gradients loj, kev tswj qhov kub thiab txias tsis zoo nyob rau hauv qhov ntsuas kub. Xaiv ib ob peb armored yog qhov tsim nyog dua vim nws xav tau lub sij hawm teb ceev ceev thiab qee theem ntawm kev ua haujlwm ntev.
4. Qhov xwm thiab lub xeev ntawm cov khoom ntsuas cuam tshuam rau kev xaiv cov thermocouples
Kev ntsuas kub ntawm cov khoom txav, cov khoom vibrating, thiab cov thawv ntim siab yuav tsum muaj zog txhua yam. Atmospheres nrog tshuaj lom neeg muaj kuab paug yuav tsum tau tiv thaiv tubing, thiab siab rwb thaiv tsev yuav tsum tau nyob rau hauv cov ntaub ntawv ntawm hluav taws xob cuam tshuam.
