Kev xaiv ntawm cov thermocouple yuav tsum tau ua raws li cov kev xav tau zoo xws li kev siv qhov kub thiab txias, qhov xav tau qhov tseeb, kev siv huab cua, 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 yog 1300 ~ 1800 ℃ thiab qhov tseeb yog qhov siab, B-hom thermocouple feem ntau yog siv; qhov tseeb tsis yog siab, thiab cov cua tso cai rau siv tungsten rhenium thermocouples. Feem ntau, tungsten rhenium thermocouples yog siv thaum kub siab tshaj 1800 ℃; 1000 ~ 1300 ℃ xav tau qhov tseeb thiab qhov tseeb siab. Muaj S-hom thermocouple thiab N-hom thermocouple; Hauv qab 1000 ℃ feem ntau siv K-hom thermocouple thiab N-hom thermocouple, hauv qab 400 ℃ feem ntau siv E-hom thermocouple; Hauv qab 250 ℃ Thiab qhov ntsuas kub tsis zoo feem ntau siv T-hom thermocouple, uas ruaj khov thiab siab precision ntawm qhov kub tsawg.
2. Kev xaiv ntawm huab cua
S-hom, B-hom, thiab K-hom thermocouples yog tsim rau siv nyob rau hauv muaj zog oxidizing thiab tsis muaj zog txo cua sov, J-hom thiab T-hom thermocouples yog haum rau tsis muaj zog oxidizing thiab txo cov cua. Yog tias siv lub raj tiv thaiv nrog airtightness zoo dua, Cov cua yuav tsum tsis txhob nruj dhau.
3. Kev xaiv ntawm durability thiab thermal teb
Thermocouples nrog cov kab hlau loj loj muaj qhov ua tau zoo dua, tab sis muaj cov lus teb qeeb dua. Rau cov thermocouples nrog lub peev xwm kub loj, cov lus teb qeeb. Thaum ntsuas kub nrog cov gradients loj, kev tswj qhov kub thiab txias tsis zoo nyob rau hauv rooj plaub ntawm kev tswj qhov kub thiab txias. Nws yuav tsum tau lub sij hawm teb ceev ceev thiab ib co degree ntawm durability, yog li nws yog tsim nyog los xaiv ib tug armored ob peb.
4. Qhov xwm thiab lub xeev ntawm cov khoom ntsuas los xaiv cov thermocouple
Kev ntsuas kub ntawm cov khoom txav, cov khoom vibrating, thiab cov hlab ntsha siab yuav tsum muaj zog txhua yam. Chemically polluted cua xav tau cov raj tiv thaiv. Nyob rau hauv cov ntaub ntawv ntawm hluav taws xob cuam tshuam, yuav tsum muaj kev rwb thaiv tsev ntau dua.
