Tsawg thiab Kub Kub Environmental Adaptability ntawm Thermocouples rau Fluid Heating Systems
Cov khoom siv hluav taws xob cua sov tau siv rau hauv cov chaw ua haujlwm qhib thiab cov chaw sab nraum zoov ntsib qhov kub thiab txias ib puag ncig cuam tshuam txhua xyoo puag ncig. Ambient kub hloov cuam tshuam rau cov kua dej kub dissipation efficiency thiab sensor sensing kev ua tau zoo, ua rau lub caij ntuj sov tswj instability. Cov thermocouples ib txwm muaj qhov tsis zoo ntawm qhov ntsuas kub tsis zoo, ua rau txo qis hauv lub caij ntuj no tsis muaj qhov kub thiab txias thiab cov teeb liab drift nyob rau lub caij ntuj sov kub, txwv tsis pub tag nrho - lub caij ruaj khov ua haujlwm ntawm cov cua kub cua sov.
Nyob rau hauv siab - qhov kub ntawm lub caij ntuj sov ib puag ncig siab tshaj 35 degree, sab nraud kub ceev ceev cov kua dej sib sau ua ke thiab ua rau kom qhov kub thiab txias ntawm cov thermocouple installation txoj haujlwm. Cov sensors zoo ib yam yog qhov ua rau thermal drift, ua rau pom qhov kub siab tshaj qhov kub ntawm cov kua dej thiab lub zog ua ntej lub sijhawm ntxov- tawm ntawm cov cua sov, ua rau cov dej kub tsis txaus thiab cuam tshuam rau cov txheej txheem tsim khoom.
Nyob rau hauv qis - qhov kub ntawm lub caij ntuj no ib puag ncig qis dua 0 degree, cov kua dej pib qhov kub thiab txias yog qhov ceev ceev. Ordinary thermocouples tau txo cov kev hloov pauv ntawm cov thermoelectric thiab ncua cov teeb liab teb, ua rau lub cev tsis tuaj yeem txiav txim qhov kub thiab txias hloov pauv. Cov cua sov ua haujlwm tsis tu ncua rau lub sijhawm ntev, ua rau muaj kev siv hluav taws xob ntau dhau thiab dej kub dhau.
Qhov kub thiab txias tiv taus cov thermocouples txais yuav cov qauv tshwj xeeb alloy thiab kaw cov qauv tsim, ua kom ruaj khov thermoelectric kev ua tau zoo hauv -20℃txog 80℃ambient kub ntau yam. Lub adaptive sensors tshem tawm qhov kev txiav txim siab raws caij nyoog thiab xyuas kom muaj kev tswj xyuas qhov kub thiab txias ntawm cov kua cua sov hauv lub xyoo.
Cov lus hauv qab no qhia txog kev ua haujlwm ntawm cov thermocouples nyob rau hauv huab cua kub ib puag ncig rau cov kua dej cua sov:

Lub caij ntuj sov huab cua hloov kho kom zoo dua tuaj yeem daws qhov mob ntawm lub caij nyoog tsis ruaj khov ntawm qhov chaw sab nraum zoov thiab qhib lub rooj cob qhia cov dej cua sov. Environmentally adaptive thermocouple configuration tswj xyuas cov cua kub zoo ib yam thiab lub zog-txuag nyhuv txhua xyoo puag ncig, txhim kho ib puag ncig kam rau ntawm cov khoom siv hluav taws xob cua sov.
Customized huab cua tiv thaiv schemes tuaj yeem tsim raws li cov yam ntxwv huab cua hauv cheeb tsam thiab cov khoom siv xa mus rau qhov chaw kom paub txog tag nrho - lub caij ua haujlwm ruaj khov ntawm cov dej cua sov.
