Yuav Ua Li Cas Xaiv Thermocouple?

Thermocouples yog qhov feem ntau sib cuag ntsuas kub ntsuas thiab ua si lub luag haujlwm tseem ceeb hauv kev ntsuas kub. Txhawm rau kom tiv nrog ntau qhov ntsuas kub ntsuas chaw ib puag ncig, muaj ntau yam uas tau tsim tawm. Lub Tebchaws Lub Tebchaws Cov Npe 7 hom nrog cov lej kawm tiav: S, B, R, K, J, J, T tau rau cov hlau pheej yig. Tus qauv hauv tebchaws stipulates txoj kev sib raug zoo ntawm thermoelectric muaj peev xwm thiab kub, tso cai yuam kev, thiab ib tus qauv kev sib koom ua ke rau cov thermocouples. Nws muaj cov khoom sib txuam tso saib rau kev xaiv. Tsis muaj qauv yooj yim thermocouples tsis zoo raws li qauv thermocouples nyob rau hauv cov nqe lus ntawm kev siv ntau yam lossis feem ntau tsis muaj cov rooj sib koom ua ke. Lawv feem ntau yog siv rau kev ntsuas hauv qee lub sijhawm tshwj xeeb.

Hauv cov ntsuas kub sib txawv, peb yuav tsum siv ntau hom thermocouples kom ntseeg tau tias qhov tseeb ntawm cov cim ntsuas kub thiab khoom siv hluav taws xob. Kev xaiv ntawm thermocouples yuav tsum tau raws cov kev txiav txim siab ntau xws li kev siv ntsuas kub, qhov yuav tsum tau ua, siv cov cua, kev kawm ntawm lub sijhawm ntsuas, thiab cov nyiaj tau los muaj nyiaj txiag.

B-Hom Thermocouple

Kev xaiv kev ntsuas qhov tseeb thiab ntsuas kub ntev thaum muaj kev ua haujlwm yog 1300 ~ 1800 degree thiab qhov tseeb yog qhov siab

S-hom lossis n-hom thermocouple

Thaum ua haujlwm kub yog 1000 ~ 1300 degree thiab qhov raug yog kuj muaj siab

K-hom lossis n-hom thermocouple

Hauv qab no 1000 degree

E-hom thermocouple

Hauv qab 400 degree

T-hom thermocouple

250 degree thiab qhov ntsuas kub tsis zoo

Tungsten-rhenium thermocouple

Thaum qhov tseeb tsis yog siab thiab cov cua tso cai, nws yog siab dua 1800 degree

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 dua yog siv, cov cai rau cov cua tsis nruj.

Rau kev ua kom ntev, xaiv ib thermocouple nrog lub taub hlau loj, tab sis cov lus teb qeeb qeeb. Rau thermocouples nrog loj tshav kub muaj peev xwm, teb qeeb. Thaum ntsuas qhov kub thiab txias nrog kev tswj qhov kub, qhov ntsuas kub yog tsis zoo nyob rau hauv qhov kub thiab txias. Yog tias koj xav tau cov sijhawm teb sai thiab qee lub sijhawm ruaj khov, nws yog qhov tsim nyog los xaiv ob peb txhais.

Qhov kub thiab txias ntsuas ntawm cov khoom txav, cov khoom siv vibrating yuav tsum muaj lub zog tiv thaiv, thiab cov hluav taws xob tsis sib haum xeeb.
