Dab tsi yog qhov tsis zoo ntawm peb cov xov hlau ntawm lub thermocouple

1. Lub hauv paus ntsiab lus ntawm thermocouples
Lub thermocouple yog ib qho sensor uas tuaj yeem hloov qhov kub thiab txias mus rau qhov hluav taws xob voltage. Nws muaj ob yam khoom sib txawv ntawm cov xov hlau, feem ntau yog tooj liab thiab tooj liab nickel alloy. Raws li cov nyhuv Seebeck, thaum qhov kev sib cuag ntawm ob yam khoom sib txawv ntawm qhov sib txawv ntawm qhov kub thiab txias, lub zog me me electromotive, los yog hu ua thermoelectric force, yog generated. Siv lub hauv paus ntsiab lus no, thermocouples tuaj yeem ntsuas qhov kub ntawm ib yam khoom.
2. Cov txheej txheem ntawm cov thermocouples
Muaj ntau txoj kev xaim rau cov thermocouples, thiab ib qho kev sib txuas yog peb txoj kev sib txuas. Peb cov xov hlau no yog liab, dawb, thiab xiav feem.
Cov kab liab yog "thermoelectric tej zaum kab", txuas mus rau qhov kub kawg ntawm lub thermocouple, uas yog qhov ntsuas kub ntawm cov khoom raug kuaj. Cov kab dawb yog "txoj kab txias kawg", txuas nrog qhov txias kawg ntawm lub thermocouple, uas yog qhov ntsuas kub ntawm qhov chaw sab nraud. Cov kab xiav yog "shielding wire" siv los txo qhov cuam tshuam ntawm sab nraud cuam tshuam cov cim ntawm kev ntsuas thermocouple.
3. Kev ua haujlwm ntawm peb cov xov hlau ntawm lub thermocouple
Cov xim sib txawv ntawm peb cov xov hlau ntawm cov thermocouple sawv cev rau cov haujlwm sib txawv thiab cov teeb liab hluav taws xob, ua lub luag haujlwm tiv thaiv cov thermocouple.
Cov teeb liab muaj peev xwm thermoelectric tau txais los ntawm kab liab yog tsim los ntawm qhov ntsuas kub ntawm qhov ntsuas kub taw tes, thiab yog siv los ntsuas qhov tseeb qhov kub ntawm cov khoom kuaj pom. Cov kab dawb txuas nrog rau qhov ntsuas kub ntawm qhov chaw ib puag ncig sab nraud kom them nyiaj rau qhov kub thiab txias tsis zoo hauv cov teeb liab muaj peev xwm thermoelectric. Cov kab xiav ua kom qhov tseeb ntawm qhov ntsuas thermocouple los ntawm kev tiv thaiv kev cuam tshuam sab nraud.
4. Siv peb lub Thermocouple Hlau
Thaum siv cov thermocouples, txuas cov kab liab mus rau qhov ntsuas kub taw tes, kab dawb mus rau qhov ntsuas kub ntawm sab nraud, thiab cov kab xiav rau cov hlau casing kom txo cov teeb liab cuam tshuam. Los ntawm kev ntsuas qhov sib txawv ntawm qhov sib txawv ntawm cov kab liab thiab dawb, qhov ntsuas kub ntawm cov khoom tuaj yeem ntsuas tau.
Thermocouples yog dav siv nyob rau hauv qhov ntsuas kub nyob rau hauv ntau yam lag luam, xws li kev lag luam tswj, khoom siv kho mob, kev kho cua sov txheej txheem, thiab lwm yam.
