Dab tsi yuav tsum tau txiav txim siab thaum xaiv ib qho thermocouple

Thermocouples yog feem ntau siv ntsuas kub ntsuas ntsuas cov ntsuas kub ntsuas ntsuas ntsuas. Lawv ncaj qha ntsuas qhov kub thiab txias rau qhov kub thiab txias rau hauv qhov ntsuas kub los ntawm cov twj ntsuas hluav taws xob (theem nrab seev). Cov tsos ntawm ntau thermocouples feem ntau sib txawv heev vim lawv cov kev xav tau, tab sis lawv cov qauv yooj yim yog ntxig tib yam. Lawv feem ntau yog tsim cov khoom loj xws li cov ntaub ntawv kub, thiab feem ntau yog siv rau cov twj paj nruag, kaw cov twj paj nruag, thiab cov neeg siv hluav taws xob, thiab cov neeg siv hluav taws xob.

Kev xaiv ntawm thermocouples yuav tsum tau raws cov kev txiav txim siab ntawm kev ua haujlwm ntau, tsim nyog qhov tseeb, kev ua haujlwm ntawm cov khoom ntsuas, kev kawm tau, thiab cov nyiaj txiag.

1. Xaiv cov kev ntsuas qhov tseeb thiab ntsuas kub ntau ntau

Thaum kev ua haujlwm kub yog nruab nrab ntawm 1300 ~ 1800 degree thiab siab precision yog qhov yuav tsum tau, B-hom thermocouples feem ntau xaiv; Qhov yuav tsum tau ua rau qhov raug yog tsis yog, thiab cov cua tso cai rau kev siv lub tungsten rhenium thermoco thermocouples. Feem ntau, tungsten rhenium thermocots yog xaiv rau qhov kub siab tshaj 1800 degree; S-hom thermocouples thiab n-hom thermoounles muaj rau siv nyob rau ntawm qhov kub kub txij 1000 txog 1300 degree, uas yuav tsum muaj qhov tseeb; K-hom thiab n-hom thermocouples feem ntau siv qis dua 1000 degree, thaum e-hom e-hom e-hom e-hom ntawv thermocoup feem ntau yog siv qis dua 400 degree; Ntawm 250 degree thiab cov ntsuas kub tsis zoo, T-hom thermocouples feem ntau siv. Ntawm tsawg kub, T-hom thermocouples yog ruaj khov thiab muaj qhov tseeb.

2. Qhov kev xaiv ntawm kev siv cov cua

S-hom, B-hom, thiab K-hom thermoounles yog tsim nyog rau kev siv hauv cov cua nab kuab thiab tsis muaj zog rau cov tshuaj oxidizing tsis muaj kuab lom thiab txo cov cua nab kuab. Yog tias lub raj tiv thaiv nrog cov huab cua zoo yog siv, qhov yuav tsum tau rau cov cua tsis nruj heev.

3. Xaiv ntawm durability thiab cov lus qhia ua thermal

Thermocouples nrog loj hlau diamet muaj cov durability zoo dua, tab sis lawv cov lus teb qeeb qeeb. Rau thermocouples nrog cov peev xwm cua sov loj hlob, lawv cov lus teb yog qeeb qeeb. Thaum ntsuas ntsuas kub nrog cov gradients loj, tswj qhov kub yog tsis zoo thaum ntsuas kub. Nws yuav tsum muaj lub sijhawm teb sai thiab muaj qee qib ua haujlwm ruaj khov, yog li xaiv cov menyuam roj hmab yog qhov tsim nyog dua.

4. Kev xaiv ntawm thermocots raws li cov khoom thiab cov xeev ntawm ntsuas ntsuas

Qhov ntsuas kub ntawm kev txav cov khoom, vibrating cov khoom, thiab cov hlab ntsha vibrating yuav tsum tau muaj zog dua, thiab cov tshuaj tiv thaiv kom muaj kuab lom, thiab kev tiv thaiv siab yog nyob rau hauv muaj kev cuam tshuam hluav taws xob.
