Yuav ua li cas yog lub thermocouple kub liab

Thermocouple yog ib qho uas nquag siv los ntsuas qhov ntsuas kub, feem ntau yog tsim los ntawm ob yam khoom sib txawv ntawm cov hlau hlau. Thaum cov thermocouples muaj qhov liab, nws feem ntau nyiam cov neeg nyiam thiab xav paub. Dab tsi yog vim li cas thiaj ua rau lub thermocouple hlawv liab?
Ua ntej, kom nkag siab txog qhov laj thawj ntawm lub thermocouple kub liab, peb yuav tsum paub txog lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm thermocouple sensor. Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub thermocouple yog ua raws li cov txiaj ntsig thermoelectric, uas txhais tau hais tias thaum ob yam khoom sib txawv ntawm cov hlau txuas ua ke los ua ib lub voj voog, qhov kub sib txawv yog tsim thaum ib qho kawg ntawm Circuit Court yog rhuab, yog li tsim hluav taws xob hluav taws xob. Qhov teeb liab voltage no yog proportional rau kub.
Txawm li cas los xij, thaum lub thermocouple rhuab mus rau qhov kub siab heev, qhov tshwm sim kub kub tuaj yeem tshwm sim. Qhov no feem ntau yog vim qhov melting point ntawm cov ntaub ntawv thermocouple yog qhov tsawg. Thaum kub tshaj nws qhov melting point, cov hlau yuav yaj thiab tej zaum yuav ua rau lub thermocouple disconnect.
Qhov thib ob, yog vim li cas rau lub thermocouple hlawv liab kuj muaj feem xyuam rau ib puag ncig thiab kev siv cov xwm txheej. Piv txwv li, yog tias lub thermocouple siv nyob rau hauv qhov chaw kub thiab txias tsis tau siv, lub thermocouple yuav overheat thiab hlawv liab. Tsis tas li ntawd, kev sib cuag tsis zoo ntawm cov thermocouples thiab conductors, overcurrent lossis overvoltage teeb meem kuj tseem tuaj yeem ua rau muaj qhov tshwm sim ntawm kub kub.
Yog li ntawd, kom tsis txhob kub hnyiab liab, nws yog ib qho tsim nyog yuav tau xyuam xim rau cov ntsiab lus hauv qab no:
Xaiv cov khoom siv thermocouple tsim nyog los xyuas kom meej tias lawv tuaj yeem tiv taus qhov ntsuas kub ntau.
Siv cov ntsuas cua txias kom tsim nyog los xyuas kom meej tias cov thermocouples tuaj yeem ua haujlwm tau zoo hauv qhov chaw kub kub.
Xyuas kom muaj kev sib cuag zoo ntawm cov thermocouple thiab tus neeg xyuas pib kom tsis txhob muaj cua sov los ntawm kev sib cuag tsis zoo.
Zam kev puas tsuaj rau cov thermocouples los ntawm overcurrent lossis overvoltage.
Hauv cov ntsiab lus, qhov redness ntawm thermocouples yog tshwm sim los ntawm melting ntawm cov ntaub ntawv hlau vim qhov kub thiab txias, raws li zoo raws li ib puag ncig thiab kev siv tsis zoo. Tsuas yog los ntawm kev xaiv cov ntaub ntawv tsim nyog, siv cov kev ntsuas cua txias kom tsim nyog, thiab kev tswj xyuas zoo thiab kev tswj xyuas peb tuaj yeem zam qhov tshwm sim ntawm thermocouple kub liab.
