Cov txiaj ntsig dab tsi Ua Kev Cai Thermocouples Muaj nyob rau hauv Kev Lag Luam Tshuaj?

Kev cai thermocouples tau dhau los ua cov cuab yeej tseem ceeb hauv kev lag luam tshuaj, qhov tseeb thiab ntau yam yog qhov tseem ceeb. Cov cuab yeej ntsuas kub tshwj xeeb no tsis yog koj cov khoom raug tshem tawm; lawv yog cov kev daws teeb meem los ua kom tau raws li cov kev xav tau tshwj xeeb ntawm cov txheej txheem tshuaj.
Kev cai thermocouples pib nrog qhov tseem ceeb tseem muaj zog Seebeck nyhuv. Lawv txoj haujlwm yog ua raws li qhov tshwm sim no, uas tsim ib qho hluav taws xob ntawm qhov sib txuas ntawm ob qhov sib txawv ntawm cov hlau los ntawm qhov sib txawv ntawm qhov kub thiab txias. Txawm li cas los xij, lawv qhov tshwj xeeb yog los ntawm kev hloov kho.
Kev cai thermocouples muab ib qho ntawm cov txiaj ntsig tseem ceeb hauv kev tuav qee qhov ntsuas kub. Cov txheej txheem hauv kev lag luam tshuaj yuav muaj qee qhov kev xav tau kub sib txawv. Nyob rau hauv ib qho kev sib cais ntawm cov tshuaj cryogenic, piv txwv li, qhov kub thiab txias tuaj yeem ncav cuag qhov qis qis ze ze rau qhov tsis muaj tseeb. Tus qauv thermocouples yuav tsis tuaj yeem ntsuas qhov ntsuas kub qis no. Hloov pauv, kev cai thermocouples tuaj yeem tsim los siv cov ntaub ntawv tsim nyog rau qhov kub qis siv xws li nickel-chromium alloys. Qhov kev tswj xyuas qhov kub thiab txias nyob rau hauv qhov kub thiab txias tau lees paub tias cov tshuaj tiv thaiv tshuaj mus raws li qhov xav tau, ib yam li muaj cov ntsuas kub tshwj xeeb rau qhov txias tshaj plaws ntawm lub caij ntuj no.
Ntawm qhov tod tes, cov thermocouples tshwj xeeb tsim los ntawm cov hlau refractory xws li molybdenum lossis tungsten-rhenium alloys tuaj yeem tiv taus cov cua kub hauv cov txheej txheem kub kub xws li cov hauv qee hom polymerization lossis kev tsim cov khoom siv zoo nkauj. Feem ntau, cov tshuaj tiv thaiv no tshwm sim deb tshaj 1000 degrees Celsius. Cov thermocouples tshwj xeeb no tiv taus cov cua kub heev, muab cov ntaub ntawv ntsuas kub uas xav tau los tswj cov tshuaj tiv thaiv, ib yam li cov hluav taws kub tiv thaiv tiv thaiv tus neeg tua hluav taws hauv hluav taws. Yog tsis muaj qhov tseeb bespoke thermocouple, qhov kub tuaj yeem tsis pom lossis raug saib xyuas tsis raug, ua rau cov khoom lag luam zoo tshaj plaws lossis teeb meem txheej txheem.
Lwm thaj chaw uas cov thermocouples bespoke muaj kev vam meej yog tshuaj lom neeg sib raug zoo. Chemical chaw muaj ntau nyob rau hauv ib tug dav spectrum ntawm corrosive hais. Muaj zog acids los yog alkalis nyob rau hauv ib tug txheej txheem yuav sai sai corrode ib tug raug thermocouple nrog ib tug hlau sheath. Kev cai thermocouples tuaj yeem tsim nrog sheaths lossis cov txheej tiv thaiv tau los ntawm cov ntaub ntawv xws li ceramic lossis qee yam corrosion-resistant polymers. Nyob rau hauv cov txheej txheem tsim sulfuric acid, piv txwv li, ib qho kev cai ua ceramic encased thermocouple tuaj yeem tiv taus cov kua qaub corrosive. Qhov no shielding shields lub thermocouple los ntawm kev puas tsuaj yog li nws yuav ua hauj lwm precisely nyob rau hauv lub hostile tshuaj ib puag ncig. Lub peev xwm los tiv thaiv cov corrosive tebchaw tau lees tias qhov ntsuas kub ntawm qhov ntsuas kub nyob ib puag ncig lub sijhawm, yog li txo qis qhov xav tau hloov pauv tsis tu ncua thiab qhov txaus ntshai ntawm cov ntaub ntawv yuam kev uas tshwm sim los ntawm kev puas tsuaj los ntawm corrosion.
Kev cai thermocouples 'daim ntawv thiab qhov loj me kuj muaj cov txiaj ntsig meej. Custom-shaped thermocouples tuaj yeem tsim kom haum raws nraim qhov lawv xav tau nyob rau hauv qee cov tshuaj reactors nrog cov geometry nyuaj lossis qhov chaw tsawg. Nws zoo li muaj tus yuam sij tsim los rau ib qho xauv. Rau qhov chaw kuaj me me-style tshuaj tiv thaiv cov hlab ntsha nrog cov yam ntxwv sab hauv, piv txwv li, tus qauv tsim micro thermocouple tuaj yeem tsim los saib xyuas qhov kub thiab txias ntawm qhov chaw tseem ceeb uas tsis tuaj yeem siv tau nrog tus qauv-qhov loj me thermocouple. Kev tswj qhov kub thiab txias ntau dua hauv cov chaw tshwj xeeb no ua tau los ntawm qhov no yuav pab cuam tshuam rau cov tshuaj tiv thaiv dav dav hauv kev ntsuas zoo.
Kev cai thermocouples kuj tuaj yeem hloov kho rau lub sijhawm tshuaj tiv thaiv. Kev ceev ceev- teb bespoke thermocouple yog qhov tseem ceeb hauv qee qhov kev nkag siab zoo rau qhov kub thiab txias hloov cov txheej txheem tshuaj, xws li cov uas cuam tshuam nrog cov txheej txheem ceev exothermic lossis endothermic. Kev nyeem ntawv kub ceev dua tuaj yeem yog los ntawm cov khoom siv thermocouple nrog cov khoom siv, kev sib txuas, thiab cov kab hluav taws xob tau teev tseg. Qhov no zoo li muaj tus xa xov xwm ceev ceev xa mus rau qhov kev tswj hwm uas tuaj yeem sau cov ntaub ntawv hloov pauv sai sai. Tom qab ntawd, lub kaw lus tswj hwm yuav hloov kho cov txheej txheem ceev kom tsis txhob muaj teeb meem xws li kev ua tsis tiav lossis kev khiav tawm yuav tsum yog qhov kub thiab txias sib txawv yam tsis muaj kev tshawb pom sai.
Kev cai thermocouples kuj tseem tuaj yeem ua ke yooj yim dua nrog cov ntaub ntawv tau txais txiaj ntsig thiab kev tswj hwm. Tej zaum lawv yuav raug tsim los siv qee qhov kev sib txuas lossis kev sib txuas lus haum rau cov nroj tsuag tshuaj tam sim no. Cov txheej txheem automation zoo dua thiab kev saib xyuas lub sijhawm tiag tiag ua tau los ntawm qhov kev sib txuas no tseem tuaj yeem ua rau Kev Cai Thermocouples, piv txwv li, tuaj yeem muab cov ntaub ntawv kub tam sim ntawd ncaj qha mus rau chav tswj hwm hauv nruab nrab ntawm cov chaw tsim tshuaj lom neeg loj, yog li tso cai rau cov neeg ua haujlwm xaiv kev kawm thiab kev hloov pauv. kom ua kom tag nrho cov txheej txheem ntau lawm.
Yuav kom suav tau, nyob rau hauv cov tshuaj sector bespoke thermocouples muaj ntau yam zoo. Cov cuab yeej tseem ceeb rau kev ntsuas qhov ntsuas kub thiab kev tswj hwm yog lawv lub peev xwm los tswj qee qhov kub thiab txias, tiv thaiv cov tshuaj tiv thaiv corrosion, haum rau cov geometry txawv txawv, muab lub sijhawm tawm tsam sai, thiab cuam tshuam nrog kev tswj hwm. Cov txiaj ntsig no thaum kawg ua rau muaj kev vam khom ntau dua, ua haujlwm tau zoo, cov txheej txheem tshuaj lom neeg zoo, yog li ua kom cov tshuaj lom neeg muaj kev vam meej.
