Thermocouple tsis ua hauj lwm yog ib qho txhaum hauv kev ua haujlwm ntawm cov tshuab kub khiav, uas yuav ncaj qha ua rau kev kaw, cov khoom seem thiab nce nqi ntau lawm. Raws li cov kws tshaj lij hluav taws xob cua sov tsom rau cov neeg khiav dej num kub, kuv yuav txheeb xyuas cov laj thawj tseem ceeb ntawm thermocouple tsis ua hauj lwm hauv kev lag luam kub khiav thiab muab cov phiaj xwm kev tiv thaiv. Qhov tsis ua hauj lwm ntawm kub khiav thermocouples feem ntau yog tshwm sim los ntawm kev kub siab - kub aging, yaj yaig, mechanical puas, installation yuam kev thiab electromagnetic cuam tshuam, es tsis yog ntuj puas. Ua ntej tshaj plaws, ntev -lub sij hawm siab- qhov kub thiab txias ua haujlwm yog thawj qhov ua rau muaj kev laus ntawm thermocouple. Cov txheej txheem kub khiav ua haujlwm nyob rau hauv qhov kub siab - ib puag ncig ntev ntev, thiab cov hlau hlau sab hauv yuav oxidize, recrystallize thiab drift, ua rau qhov ntsuas kub tsis raug. Yog hais tias qhov kub thiab txias ua hauj lwm tshaj qhov txwv ntawm lub thermocouple rau lub sij hawm ntev, qhov kev laus yuav nrawm dua, thiab txawm tias qhib Circuit Court thiab luv Circuit Court yuav tshwm sim. Thib ob, yaj xau thiab yaig yog qhov tshwj xeeb rau kev lag luam kub khiav. Thaum cov yas yaj nkag mus rau sab hauv ntawm lub thermocouple, nws yuav carbonize lub rwb thaiv tsev txheej, ua rau tus neeg xyuas pib ua kom puas thiab ua rau tsis ua tiav. Mechanical stress thiab installation tsis raug kuj tseem ceeb heev. Nyob rau hauv tus txheej txheem ntawm installation thiab hloov, ntau bending, rub thiab extrusion yuav ua puas lub internal conductor ntawm lub thermocouple. Kev co tsim tawm thaum lub sijhawm ua haujlwm ntawm lub tshuab txhaj tshuaj molding tseem yuav ua rau cov thermocouple hlws ris xoob lossis lub cable tawg. Tsis tas li ntawd, kev sib cuag tsis zoo ntawm lub connector, dej vapor thiab roj paug yuav ua rau cov teeb liab tsis ruaj khov thiab ua kom tsis muaj zog. Electromagnetic cuam tshuam tsim los ntawm lub tshuab hluav taws xob kub kub kuj tseem yuav ua rau cov teeb liab drift, uas yog yuam kev rau kev puas tsuaj rau thermocouple. Txhawm rau txo qis qhov tsis ua haujlwm, cov neeg siv yuav tsum ua qauv kev teeb tsa, zam dhau-kev ua haujlwm kub, ntxiv dag zog rau kev tiv thaiv kev sib khi thiab tsis tu ncua xyuas cov cable thiab txuas. Xaiv cov thermocouples nrog siab -kub tsis kam thiab tiv thaiv -seepage tsim tuaj yeem txhim kho lub neej ua haujlwm tau zoo. Kev nkag siab txog qhov tsis ua hauj lwm mechanism pab cov tuam txhab lag luam coj kev tiv thaiv ua ntej, txo qis sijhawm thiab txhim kho kev ruaj khov. Rau qhov kub khiav qhov system, txo cov thermocouple tsis ua hauj lwm tus nqi yog sib npaug rau kev txhim kho tag nrho cov kev ua haujlwm zoo thiab cov txiaj ntsig kev lag luam.333
