Cov ntaub ntawv dab tsi tuaj yeem txhim kho lub neej ntev ntawm cov cuab yeej ntsuas kub hauv qhov kub thiab txias?

Nyob rau hauv cheeb tsam ntawm ntau-kub cov kev pab cuam, kom paub tseeb tias lub sturdiness ntawm kub dimension system yog ib qho tseem ceeb kev txhawj xeeb. Qhov kev nyiam ntawm cov khoom tuaj yeem ua rau muaj kev sib txawv loj hauv lub neej thiab kev ua haujlwm tag nrho ntawm cov khoom siv. Daim duab lub qhov cub tawg lossis cov txheej txheem kev lag luam kub ntau dhau qhov uas qhov ntsuas kub kom raug yog qhov tseem ceeb. Nyob rau hauv xws li ib puag ncig ntau dhau, cov khoom tsim nyog tuaj yeem ntsib qhov sov sov thiab ua kom ntev lub neej ntawm qhov dimension.
Thermocouples feem ntau yog siv rau qhov ntsuas kub ntawm qhov kub thiab txias. Txhawm rau txhim kho lawv txoj sia, cov khoom siv tseeb yuav raug ua haujlwm. Ib daim ntaub zoo li no yog platinum. Platinum muaj qhov tshwj xeeb tshaj plaws melting qhov tseem ceeb thiab zoo heev tiv thaiv oxidation thiab corrosion ntawm qhov kub thiab txias. Platinum thermocouples tuaj yeem ntsib qhov kub thiab txias ntau npaum li puag ncig 1800 theem Celsius thiab tuav lawv qhov tseeb thiab sib npaug ntawm lub sijhawm ntev. Lub sturdiness ntawm platinum ua rau nws ib tug zoo meej nyiam rau cov kev pab cuam nyob rau hauv lub sij hawm ntev kev cia siab yuav tsum tau.
Rhodium yog txhua lwm yam khoom muaj nqis hlau uas tuaj yeem ua kom zoo nkauj lub neej ntawm qhov kub thiab txias qhov system. Thaum sib xyaw nrog platinum, nws bureaucracy platinum-rhodium thermocouple, uas ua rau muaj kev tiv thaiv zoo heev rau qhov kub thiab txias ib puag ncig. Rhodium cov khoom melting ntau dhau thiab cov tshuaj sib npaug ua rau muaj kev cuam tshuam rau lub zog ntawm cov thermocouple, ua kom paub tseeb qhov ntsuas kub zoo txawm tias tom qab nthuav tawm mus rau qhov sov so ntau dhau.
Ntxiv nrog rau cov khoom muaj nqis hlau, ceramics kuj tuaj yeem siv los txhim kho lub neej ntawm qhov kub thiab txias qhov system. Cov khoom siv ceramic muaj qhov ua kom sov zoo heev thiab tuaj yeem ntsib mus rau qhov kub thiab txias heev uas tsis muaj degrading. Ceramic sheaths lossis insulators tuaj yeem tiv thaiv cov xaim thermocouple los ntawm ib puag ncig nyuaj, txo qis kev hem thawj ntawm kev puas tsuaj thiab ua rau lawv lub neej ntev. Piv txwv li, nyob rau hauv aerospace cov kev pab cuam los yog ntau tshaj-kub kev tshawb fawb chaw soj nstuam, ceramic-insulated thermocouples yog nquag siv rau nws los yog nws sturdiness thiab kev cia siab rau.
Lwm daim ntaub uas tuaj yeem txhim kho lub neej ntev ntawm qhov ntsuas qhov ntsuas kub yog Inconel. Inconel yog npib tsib xee-raws li tag nrho cov alloy uas muaj ntau lub zog thiab zoo heev tiv thaiv oxidation thiab corrosion ntawm qhov kub thiab txias. Inconel thermocouples lossis cov ntsuas kub ntsuas tuaj yeem ntsib qhov kev sim siab ntawm qhov kub thiab txias ib puag ncig thiab tuav lawv cov kev ua tau zoo txhua lub sijhawm. Qhov ruaj khov ntawm Inconel ua rau nws tsim nyog rau cov kev pab cuam hauv lub zog tiam, petrochemical, thiab kev lag luam sib txawv nyob qhov twg qhov kub thiab txias yog qhov kev sib tw tsis tu ncua.
Kev teeb tsa kom raug thiab khaws cia yog qhov tseem ceeb rau kev ua kom lub neej ntev ntawm qhov ntsuas kub qhov system. Xyuas kom meej tias lub kaw lus tau zoo mounted thiab tiv thaiv los ntawm txhua yam kev ntxhov siab, kev vibrations, thiab hluav taws xob cuam tshuam tuaj yeem pab cawm koj lub sijhawm tsis ua haujlwm. Kev ntsuas tsis tu ncua thiab kev tshuaj xyuas kuj tuaj yeem pom cov tsos mob thiab cov tsos mob ntawm kev puas tsuaj lossis kev puas tsuaj thaum ntxov, ua kom muaj txiaj ntsig zoo rau lub sijhawm khaws cia lossis hloov pauv. Hauv kev xaus, cov khoom uas suav nrog platinum, rhodium, ceramics, thiab Inconel tuaj yeem txhim kho lub neej ntawm qhov ntsuas kub hauv qab qhov kub thiab txias. Los ntawm kev xaiv cov khoom tsim nyog thiab ua raws li kev teeb tsa thiab kev khaws cia, nws muaj peev xwm ua tau kom paub tseeb tias qhov ntsuas kub kom raug thiab nthuav dav lub neej ntawm cov kab ke hauv qhov chaw siab tshaj plaws.
