Kev Siv Cov Khoom Siv Zoo Li Cas Txhim Kho Lub Sij Hawm ntawm Thermocouples hauv Ib puag ncig hnyav?

Cov khoom siv qib siab muaj peev xwm tiv taus qhov kub thiab txias. Nyob rau hauv qhov chaw huab cua zoo li lub cub tawg lossis lub foob pob hluav taws, qhov kub thiab txias tuaj yeem nce mus rau qib siab heev. Cov ntaub ntawv xws li cov hlau refractory lossis ceramics tuaj yeem ua haujlwm hauv cov thermocouples los lav lawv cov haujlwm yam tsis muaj melting lossis deteriorating. Piv txwv li, ib lub thermocouple tsim nrog lub ceramic insulator tuaj yeem tswj qhov kub siab tshaj qhov uas yuav ua rau cov thermocouple ib txwm siv tsis tau.

Lawv muaj kev tiv thaiv corrosion. Nyob rau hauv ib puag ncig hnyav tshuaj los yog dej ntsev, corrosion tuaj yeem ua rau lub thermocouple sai sai. Cov ntaub ntawv zoo xws li cov alloys tshwj xeeb lossis cov txheej txheem tuaj yeem muab kev tiv thaiv corrosion. Qhov no ua rau lub thermocouple ua haujlwm kom raug txawm tias muaj cov tshuaj corrosive. Piv txwv li, ib lub thermocouple nrog cov txheej txheem corrosion-resistant tuaj yeem siv rau hauv cov khoom siv tshuaj tsis raug mob los ntawm cov tshuaj.

Cov ntaub ntawv qib siab tuaj yeem tiv nrog kev kub ntxhov. Hauv kev siv dej hiav txwv sib sib zog nqus lossis cov txheej txheem kev lag luam siab, lub siab tuaj yeem ua rau khaus heev. Cov ntaub ntawv uas muaj zog thiab tuaj yeem tiv taus cov kev ntxhov siab no yog qhov tseem ceeb rau cov thermocouples. Piv txwv li, ib lub thermocouple ua nrog lub zog muaj zog hlau alloy tuaj yeem ua haujlwm nyob rau hauv qhov chaw sib sib zog nqus dej hiav txwv uas lub siab yog ntau zaus ntau dua li ntawm qhov chaw.

Lawv tiv taus kev vibration thiab poob siab. Hauv cov ntawv thov xws li aerospace lossis cov tshuab hnyav, cov thermocouples raug kev co thiab kev poob siab. Cov ntaub ntawv zoo tshaj plaws uas muaj cov khoom siv thiab tuaj yeem nqus tau cov kev poob siab tuaj yeem ua kom ntseeg tau tias cov thermocouple tseem nyob ruaj khov thiab ua haujlwm zoo. Piv txwv li, ib lub thermocouple nrog ib tug saj zawg zog cable ua los ntawm ib tug tshwj xeeb cov khoom muaj peev xwm tiv taus lub vibrations ntawm lub aircraft engine yam tsis tau tawg.
