Txoj kev paub qhov txawv ntawm platinum xov hlau hauv thermocouples
Tso lus
1. Lub thermocouple yog dab tsi?
Lub thermocouple yog ib qho khoom siv rau kev ntsuas qhov kub thiab txias uas siv cov khoom siv hluav taws xob los ntsuas qhov kub thiab txias. Thermocouples feem ntau yog tsim los ntawm ob yam khoom hlau sib txawv, ib qho yog platinum hlau.
Vim li cas thiaj siv platinum hlau?
Platinum hlau yog ib qho ntawm cov khoom siv feem ntau siv hauv cov thermocouples vim tias nws muaj qhov kub tsis kam coefficient, siab ruaj khov, thiab kub tsis kam. Platinum hlau tuaj yeem muab qhov ntsuas kub kom raug raws li ntau qhov kub thiab txias.
3. Txoj hauv kev kom paub qhov txawv ntawm platinum xov hlau hauv thermocouples
Rau platinum xaim ntawm thermocouples, peb tuaj yeem paub qhov txawv ntawm ob txoj hauv qab no:
Ncaj nraim saib cov xim
Ntau hom platinum hlau yuav muaj xim sib txawv. Feem ntau hais lus, platinum hlau ntawm S-hom thermocouples yog xim dub, platinum hlau ntawm B-hom thermocouples yog grey, thiab platinum hlau xim ntawm R-hom thiab S-hom thermocouples yog me ntsis zoo sib xws, ob qho tib si nthuav tawm lub teeb ci liab xim. .
Siv cov cuab yeej kuaj
Yog tias kev ntxub ntxaug xim tsis tuaj yeem ua tau, peb tuaj yeem siv cov cuab yeej kuaj tshwj xeeb txhawm rau txheeb xyuas tus nqi tiv thaiv ntawm platinum hlau. Qhov tseem ceeb ntawm kev tiv thaiv ntawm ntau hom platinum xov hlau yuav txawv ntawm qhov kub thiab txias.
4. Ceev faj
Thaum sib txawv thermocouple platinum xov hlau, cov ntsiab lus hauv qab no yuav tsum raug sau tseg:
Ceev faj thaum ua haujlwm kom tsis txhob ua rau cov hlau platinum puas.
Yog tias koj tsis paub meej txog txoj kev sib txawv, koj tuaj yeem sab laj tus kws tshaj lij rau kev pab.
Qhov kev hloov ntawm qhov kub thiab txias tuaj yeem cuam tshuam tus nqi tiv thaiv ntawm platinum hlau ntawm lub thermocouple, yog li nws yog ib qho tseem ceeb uas yuav tsum tau xyuam xim rau qhov kub thiab txias thaum ntsuas.
Hauv luv luv, los ntawm kev soj ntsuam ncaj qha rau cov xim lossis siv cov cuab yeej ntsuas, peb tuaj yeem paub qhov txawv ntawm platinum hlau ntawm lub thermocouple, yog li ua tiav qhov ntsuas kub kom raug.
