Kev paub sib qhia ntawm cov qauv sib txawv ntawm cov khub niam txiv kub

Cov lej kawm tiav ntawm cov thermocouples feem ntau suav nrog S, R, B, N, K, E, J, T, thiab lwm yam. Ntawm lawv, S, R, thiab B yog cov khoom muaj nqi hlau thermocouples, thaum N, K, E, J, thiab T belongs rau pheej yig hlau thermocouples.

Cov yam ntxwv ntawm S-qib thermocouples yog qhov muaj zog oxidation tsis kam, thiab lawv tsim nyog rau kev siv txuas ntxiv hauv oxidizing thiab inert atmospheres. Lub sijhawm siv sijhawm ntev yog 1400 degree, thiab siv sijhawm luv luv yog 1600 degree. Ntawm tag nrho cov thermocouples, S-qib thermocouple muaj qhov raug siab tshaj plaws thiab feem ntau yog siv los ua tus qauv thermocouple; Piv nrog rau S-qib thermocouple, R-qib thermocouple muaj yuav luag zoo tib yam kev kawm tshwj tsis yog rau cov thermoelectric electromotive quab yuam yog li ntawm 15% siab dua;

B kawm tiav thermocouple muaj ib qho me me thermal electromotive quab yuam ntawm chav tsev kub, yog li nws feem ntau tsis tas yuav them nyiaj xaim thaum ntsuas. Nws siv sijhawm ntev kub yog 1600 degree thiab siv sijhawm luv luv yog 1800 degree. Nws tuaj yeem siv rau hauv oxidizing lossis nruab nrab cua, lossis siv sijhawm luv luv hauv lub tshuab nqus tsev.

Cov yam ntxwv ntawm N qib thermocouples yog qhov muaj zog kub oxidation tsis kam ntawm 1300 degree, kev ruaj ntseg zoo ntawm thermoelectric electromotive quab yuam thiab kev tsim tawm ntawm lub sij hawm luv luv thermal, zoo tiv thaiv hluav taws xob hluav taws xob thiab qhov kub thiab txias, thiab tuaj yeem hloov pauv S qib. thermocouples;

Cov yam ntxwv ntawm K-qib thermocouples yog muaj zog antioxidant kev ua tau zoo, thiab lawv tsim nyog rau kev siv txuas ntxiv hauv oxidizing thiab inert cua. Kev siv lub sijhawm ntev kub yog 1000 degree, thiab siv sijhawm luv luv yog 1200 degree. Feem ntau siv los ntawm tag nrho cov thermocouples;

Cov yam ntxwv ntawm cov thermocouple nrog tus lej E kawm tiav yog qhov uas feem ntau siv cov thermocouples, nws cov thermoelectric electromotive quab yuam yog siab tshaj, uas txhais tau hais tias nws muaj qhov siab tshaj plaws. Nws yuav tsum tau siv tas li nyob rau hauv oxidizing thiab inert cua ntawm qhov kub ntawm 0-800 degree ;

Cov yam ntxwv ntawm cov thermocouple nrog J kawm tiav tus lej yog tias nws tuaj yeem siv tau rau hauv ob qho tib si oxidizing cua (nrog rau qhov kub siab tshaj ntawm 750 degree) thiab txo cov cua sov (nrog rau qhov kub siab tshaj ntawm 950 degree), thiab tiv taus H2 thiab CO. gas corrosion. Nws feem ntau yog siv rau hauv cov roj refining thiab tshuaj lom neeg kev lag luam;

Cov yam ntxwv ntawm T qib thermocouples yog tias lawv muaj qhov raug siab tshaj plaws ntawm txhua qhov pheej yig hlau thermocouples thiab feem ntau yog siv los ntsuas kub hauv qab 300 degree.
