Vim li cas thiaj muaj qhov sib txawv ntawm T-hom thermocouples thiab K-hom thermocouples

Thermocouples yog dav siv ntsuas kub ntsuas hauv kev lag luam thiab kev tshawb fawb. Ntawm cov thermocouples, T-hom thiab K-hom thermocouples yog ob hom. Txawm hais tias lawv txhua tus siv los ntsuas qhov kub thiab txias, lawv muaj qee qhov sib txawv hauv kev siv tswv yim. Cov hauv qab no yuav qhia qhov txawv ntawm T-hom thermocouples thiab K-hom thermocouples.

1. Cov yam ntxwv ntawm T-hom thermocouples
T-hom thermocouple yog tsim los ntawm tooj liab thiab cov pa thermocouple alloy tooj liab nickel. Nws qhov ntsuas kub yog feem ntau ntawm -200 degree C thiab 350 degree C, uas tuaj yeem ncav cuag 450 degree C. T-hom thermocouples muaj kev ruaj khov thiab muaj txiaj ntsig zoo hauv kev ntsuas cov khoom siv qis melting xws li tooj liab thiab txhuas. Yog li ntawd, T-hom thermocouples tau dav siv hauv kev lag luam xws li hlau, metallurgy, thiab kev lag luam tshuaj.

2. Cov yam ntxwv ntawm K-hom thermocouples
K-hom thermocouple yog ib qho ntawm cov thermocouples uas nquag siv, muaj cov nickel chromium alloy thiab npib tsib xee aluminium alloy. Nws qhov ntsuas kub yog feem ntau ntawm -200 degree C thiab 1260 degree C, uas tuaj yeem ncav cuag 1370 degree C. K-hom thermocouples muaj qhov rhiab heev thiab oxidation tsis kam, thiab haum rau ntau yam kev ua haujlwm thiab ib puag ncig, tshwj xeeb tshaj yog rau Kev ntsuas kub siab. Yog li ntawd, K-hom thermocouples tau siv dav hauv kev lag luam xws li petrochemicals, hluav taws xob, thiab qhov cub.

3. Lub thermocouple twg yog qhov tsim nyog rau koj?
Kev xaiv ntawm T-hom thermocouples lossis K-hom thermocouples nyob ntawm qhov xav tau tiag tiag. Yog tias tsim nyog los ntsuas qhov ntsuas kub hauv qhov ntsuas kub tsawg, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig uas muaj cov khoom siv melting tsawg xws li tooj liab thiab txhuas, T-hom thermocouples yog qhov kev xaiv zoo. Rau qhov dav ntawm qhov kub thiab txias ib puag ncig, K-hom thermocouples yog qhov tsim nyog dua.

4. Yuav siv cov thermocouples kom raug li cas
Kev siv kom raug ntawm T-hom thiab K-hom thermocouples yog qhov tseem ceeb. Ua ntej, cov hom thermocouple haum yuav tsum raug xaiv raws li kev thov tshwj xeeb. Tom qab ntawd, thaum siv, yuav tsum tau them nyiaj tshwj xeeb rau kev tiv thaiv kev sib txuas sab nraud ntawm cov thermocouple kom tsis txhob muaj kev sib txuas xoob los ntawm sab nraud quab yuam lossis ib puag ncig. Tsis tas li ntawd, kev txheeb xyuas tsis tu ncua thiab calibration yuav tsum tau ua los xyuas kom meej qhov ntsuas thiab kev ntseeg siab ntawm thermocouples.

5. Lwm hom thermocouples
Ntxiv rau T-hom thermocouples thiab K-hom thermocouples, kuj tseem muaj ntau hom thermocouples. Piv txwv li, J-hom thermocouples haum rau qhov kub thiab txias ntawm 0 degree C mus rau 750 degree C, thaum E-hom thermocouples haum rau qhov kub ntawm -200 degree C txog 900 degree C. Txhua hom ntawm cov thermocouple muaj nws cov kev thov tshwj xeeb thiab qhov zoo, thiab nws yog ib qho tseem ceeb uas yuav tsum xaiv cov thermocouple tsim nyog raws li qhov xav tau sib txawv.

6. Cov lus xaus
Ob leeg T-hom thiab K-hom thermocouples feem ntau siv cov thermocouple hom thiab ua lub luag haujlwm tseem ceeb hauv kev ntsuas kub. Lawv txawv nyob rau hauv cov khoom muaj pes tsawg leeg, qhov kub thiab txias, thiab siv tau. Xaiv hom thermocouple tsim nyog, siv thiab tswj kom raug, yog qhov tseem ceeb los xyuas kom meej qhov tseeb thiab kev ntseeg siab ntawm kev ntsuas kub.
