Yuav txiav txim siab seb hom thermocouple yuav siv li cas

1. Lub hauv paus ntsiab lus ntawm thermocouples
Thermocouples yog ib qho khoom siv ntsuas kub uas siv cov thermoelectric effect ntawm ob lub hlau sib txawv los ntsuas qhov kub thiab txias. Raws li cov qauv kev ua haujlwm sib txawv thiab cov ntawv thov, cov thermocouples tuaj yeem muab faib ua ntau hom.

2. Raws li cov khoom siv
Raws li cov khoom siv hluav taws xob ntawm cov khoom sib txawv, cov thermocouples tuaj yeem muab faib ua Pt Rh / Pt thermocouples, Cu CuNi thermocouples, Fe Constantan thermocouples, thiab lwm yam. Thermocouples ua los ntawm cov khoom sib txawv muaj qhov sib txawv ntawm qhov kub thiab txias.

3. Ua haujlwm kub
Raws li qhov sib txawv ntawm kev ua haujlwm kub, cov thermocouples tuaj yeem muab faib ua cov thermocouples siab, nruab nrab kub thermocouples, thiab cov thermocouples qis. Kub kub thermocouples yog tsim rau qhov kub thiab txias ib puag ncig siab tshaj 1000 degree, xws li qhov cub ntsuas kub; Qhov nruab nrab kub thermocouples yog tsim rau ntsuas kub ntawm 400 degree thiab 1000 degree; Cov thermocouples uas tsis tshua muaj siab yog tsim rau qhov kub thiab txias ib puag ncig xws li -270 degree txog 400 degree .

4. Daim ntawv thov scenarios
Raws li qhov sib txawv ntawm daim ntawv thov scenarios thiab tej yam kev mob, thermocouples yuav muab faib ua tawg-pov thawj thermocouples, corrosion-resistant thermocouples, reinforced thermocouples, thiab lwm yam. Tawg pov thawj thermocouples yog tsim rau explosive ib puag ncig thiab muaj peev xwm tiv thaiv kev huam yuaj tshwm sim los ntawm sparks; Corrosion resistant thermocouples yog tsim rau corrosive gas los yog kua ib puag ncig thiab tuaj yeem txhim kho lub neej kev pab cuam ntawm thermocouples; Cov thermocouple reinforced tau raug txhawb rau hauv kev tsim thiab tsim nyog rau kev ua haujlwm hnyav.

5. Cov txheej txheem rau kev txiav txim siab thermocouples
Txhawm rau txiav txim siab seb hom thermocouple siv hom twg, thawj kauj ruam yog los txiav txim siab qhov ntsuas kub thiab qhov yuav tsum tau ntsuas. Tom qab ntawd xaiv hom thermocouple uas tsim nyog raws li qhov tseeb daim ntawv thov scenario thiab ib puag ncig tej yam kev mob. Nyob rau tib lub sijhawm, yam xws li cov khoom siv, kev ua haujlwm kub thiab kev tiv thaiv qib ntawm cov thermocouple kuj yuav tsum tau xav txog. Tom qab ntawd, raws li cov khoom siv los yog cov lus qhia kev tshaj lij, xaiv cov thermocouples haum rau kev teeb tsa thiab siv.

6. Ceev faj
Thaum xaiv thiab siv cov thermocouples, cov qauv tsim nyog thiab cov kev qhia tshwj xeeb yuav tsum ua raws. Thaum lub sij hawm installation, yuav tsum tau them nyiaj mloog mus rau kev sib cuag thiab fixation ntawm thermocouples kom paub meej qhov tseeb ntsuas. Nyob rau tib lub sijhawm, cov thermocouples yuav tsum tau kuaj xyuas tsis tu ncua thiab ntsuas kom tsis txhob ntsuas qhov yuam kev los ntawm kev laus lossis kev puas tsuaj. Yog tias lub thermocouple puas los yog ua haujlwm tsis zoo, nws yuav tsum tau hloov lossis kho kom raws sijhawm.

Xaiv qhov tsim nyog thermocouple yog qhov tseem ceeb rau kev ntsuas qhov ntsuas kub kom raug. Raws li cov ntawv thov sib txawv thiab cov xwm txheej xwm txheej, kev xaiv tuaj yeem ua raws li cov khoom siv, kev ua haujlwm kub, thiab kev siv ib puag ncig ntawm thermocouple. Thaum ntsib teeb meem kev xaiv, nws raug nquahu kom sab laj nrog cov kws tshaj lij lossis xa mus rau cov ntawv qhia kev ntawm cov khoom siv.
