Yuav Ua Li Cas Thermocouples Hloov Rau Kev Siv Hauv Ib puag ncig High-Radiation?

Ib txoj hauv kev yog siv cov tshuaj tiv thaiv hluav taws xob. Cov ntaub ntawv suav nrog cov alloys zoo lossis ceramics tuaj yeem ntsib ntau dhau ntawm cov hluav taws xob uas tsis muaj kev puas tsuaj loj heev. Piv txwv li, Hastelloy lossis Inconel alloys raug lees paub rau nws qhov kev tiv thaiv hluav taws xob thiab tuaj yeem siv sab hauv kev tsim cov thermocouples rau kev siv hluav taws xob ntau dhau. Cov tshuaj no tuaj yeem pab ua kom muaj kev ncaj ncees thiab raug ntawm cov thermocouple txawm nyob rau hauv qhov muaj hluav taws xob tsis zoo.
Lwm version yog los muab kev tiv thaiv. Cov ntaub thaiv npog tuaj yeem nkag rau lub thermocouple los tiv thaiv nws los ntawm hluav taws xob. Qhov no tej zaum yuav nyob rau hauv cov duab ntawm cov hlau lead los yog sib txawv hnyav hlau uas nqus los yog deflect hluav taws xob. Piv txwv li, ib tus neeg saib xyuas cov hlau lead tuaj yeem nyob thoob plaws lub thermocouple kom txo cov hluav taws xob ua kom tiav. Qhov no ua rau kom txo tau qhov tshwm sim ntawm hluav taws xob ntawm lub thermocouple thiab xyuas kom meej qhov ntsuas kub ntxiv.
Thermocouples kuj tuaj yeem tsim nrog cov ntsiab lus tsis txaus. Nyob rau hauv qhov chaw muaj hluav taws xob ntau dhau, muaj kev phom sij rau cov thermocouple. Los ntawm muaj cov ntsiab lus rov ua dua, suav nrog ntau dua ib qho kev sib txuas ntawm cov thermocouple lossis cov khoom siv thaub qab, cov khoom siv tuaj yeem ua kom muaj txiaj ntsig txawm tias ib qho khoom tawg nrog kev pab ntawm kev siv hluav taws xob. Piv txwv li, ib lub thermocouple nrog lossis cov junctions ntxiv tuaj yeem muab cov kev ntsuas thaub qab yog tias ib qho kev sib tshuam tsis ua haujlwm vim muaj hluav taws xob raug.
Calibration thiab tshuaj xyuas rau qhov chaw muaj hluav taws xob ntau dhau yog qhov tseem ceeb heev. Thermocouples yuav tsum tau siv nyob rau hauv ntau tshaj-kib hluav taws xob chaw yuav tsum tau calibrated thiab soj ntsuam nyob rau hauv qab cov xwm txheej zoo li cov uas lawv yuav stumble raws li nyob rau hauv kev siv tiag tiag. Qhov no ua rau kom paub tseeb tias lawv tuaj yeem muab qhov ntsuas kub kom raug txawm nyob hauv qhov muaj hluav taws xob. Piv txwv li, nthuav tawm cov thermocouple kom paub txog qib ntawm hluav taws xob tag nrho los ntawm kev kuaj xyuas tuaj yeem pab txiav txim siab nws qhov kev ua tau zoo thiab raug.
Thaum kawg, tsis nres taug qab thiab tiv thaiv yog qhov tseem ceeb. Nyob rau hauv ib puag ncig-kib hluav taws xob ntau dhau, cov thermocouple yuav tsum tau saib xyuas cov tsos mob thiab cov tsos mob ntawm kev puas tsuaj lossis ua haujlwm tsis zoo. Txhua yam teeb meem yuav tsum tau daws tam sim ntawd kom paub tseeb tias qhov tsis tu ncua thiab kev ntseeg siab ntawm qhov ntsuas kub. Piv txwv li, kev tshuaj xyuas ib ntus thiab rov kho dua tshiab tuaj yeem pab nrhiav thiab txheeb xyuas txhua yam teeb meem uas tuaj yeem tshwm sim vim muaj hluav taws xob.
