Dab tsi yog qhov zoo ntawm kev siv Alumina Sheaths hauv Thermocouples rau Aerospace Applications?

Alumina sheaths muaj qhov tshwj xeeb tshaj plaws-kub tsis kam. Nyob rau hauv aerospace, cov thermocouples feem ntau yog uncovered rau extraordinarily kub kub nyob rau hauv ib co theem nyob rau hauv lub davhlau thiab nyob rau hauv lub engine ua hauj lwm. Alumina tuaj yeem tiv taus qhov kub thiab txias ntau npaum li ib puag ncig 1700 degrees Celsius, ua rau nws zoo meej rau cov chaw cuam tshuam. Qhov no tau lees paub qhov ntsuas kub kom raug txawm nyob rau hauv qhov kev kub ntxhov siab tshaj plaws.
Lawv muab hluav taws xob rwb thaiv tsev. Hauv cov haujlwm hauv aerospace, hluav taws xob cuam tshuam tuaj yeem cuam tshuam rau qhov tseeb ntawm kev nyeem ntawv kub. Alumina yog ib qho hluav taws xob zoo heev, uas ua rau kom txuag tau koj lub suab nrov hluav taws xob thiab cuam tshuam los ntawm kev cuam tshuam cov teeb liab thermocouple. Qhov no cuam tshuam rau qhov kev cia siab ntxiv thiab ntsuas qhov ntsuas kub kom raug.
Alumina sheaths yog chemically inert. Nyob rau hauv ib puag ncig aerospace, muaj peev xwm tshaj tawm rau ntau hom tshuaj sib xyaw thiab roj. Alumina yog pov thawj tiv thaiv cov tshuaj lom neeg ntau tshaj plaws, ua kom cov thermocouple nyob twj ywm tsis cuam tshuam nrog kev pab ntawm kev siv cov tshuaj no. Qhov no ua rau kom muaj kev ncaj ncees thiab qhov tseeb ntawm qhov ntsuas kub ntawm lub sijhawm.
Lawv muaj lub zog mechanical xav tau. Aerospace cov kev pab cuam feem ntau muaj kev vibrations, shocks, thiab sib txawv mechanical stresses. Alumina sheaths muaj zog thiab tuaj yeem tiv thaiv cov rog uas tsis muaj kev tawg lossis deforming. Qhov no ua rau tiv thaiv cov thermocouple thiab xyuas kom nws ua haujlwm siab ntev txawm tias nyob rau hauv ib puag ncig hnyav.
