Yuav ua li cas kom paub tseeb kev soj ntsuam nrog Coal Chemical Thermocouples?

Kev saib xyuas kom raug siv cov thermocouples yog qhov tseem ceeb heev hauv qhov nyuaj thiab xav tau ib puag ncig ntawm cov txheej txheem thee chemical. Cov cuab yeej ntsuas kub no yog qhov muag thiab pob ntseg uas muab cov ntaub ntawv tseem ceeb uas xav tau rau kev ua haujlwm zoo thiab muaj kev nyab xeeb ntawm cov nroj tsuag tshuaj.
Raws li cov nyhuv Seebeck-qhov twg qhov sib txawv ntawm qhov kub thiab txias ua rau qhov hluav taws xob ntawm qhov sib txuas ntawm ob qhov sib cais ntawm cov hlau-coal tshuaj thermocouples Ib qho tom qab ntawd hloov qhov hluav taws xob no mus rau qhov ntsuas kub. Txawm li cas los xij, ntau lub ntsiab lus tseem ceeb yuav tsum tau coj mus rau hauv tus account kom tau txais kev saib xyuas kom raug.
Ua ntej, kev xaiv cov khoom siv thermocouple haum yog qhov tseem ceeb heev. Thermocouples siv nyob rau hauv cov ntawv siv thee chemical tuaj yeem nyob rau hauv cov khoom abrasive, corrosive gasses, thiab kub kub. Cov xaim thermocouple yog ua los ntawm cov hlau tshwj xeeb kom muaj sia nyob raws li qhov xav tau ib puag ncig. Piv txwv li, qhov zoo kub-kub endurance thiab corrosion-resistant zoo ntawm npib tsib xee-raws li alloys ua rau lawv nrov heev. Nyob rau hauv lub tshav kub zoo ntawm lub thee gasification reactor los yog lub qhov cub coking, cov alloys yuav khaws lawv cov qauv kev ncaj ncees thiab cov khoom hluav taws xob. Cov ntaub ntawv hwm zoo no cia cov thermocouple ua haujlwm tau zoo nyob rau hauv qhov chaw muaj kev kub ntxhov ntawm kev siv tshuaj lom neeg, ib yam li lub nkoj tsim tau zoo tuaj yeem sib tham txog cov nthwv dej nyuaj.
Qhov tseeb ntawm cov thermocouple nyob ntawm ntau yam ntawm nws tus qauv tsim thiab. Ua tib zoo tsim yog qhov sib txuas ntawm ob lub hlau uas qhov ntsuas kub-sensitive voltage yog tsim. Kev sib txuas tsim nyog tau lees paub meej cov thermocouple teb rau qhov kub thiab txias. Tsis tas li ntawd tseem ceeb heev yog kev tiv thaiv npog ib puag ncig lub thermocouple. Nws yuav tsum tau tsim los ntawm kev siv cov khoom tiv thaiv corrosion thiab kis kab mob. Piv txwv li, ceramic los yog qib high-grade alloy sheath tiv thaiv cov thermocouple los ntawm kev puas tsuaj los ntawm cov tshuaj nyob ib puag ncig hauv cov txheej txheem thee liquefaction nrog rau ntau hom tshuaj. Ua raws li kev tiv thaiv, lub tsho tiv no tiv thaiv cov ntsiab lus kub-sensing sab hauv.
Kev saib xyuas cov thermocouple kom raug yog nyob ntawm calibration. Txhawm rau piav qhia txhua qhov kev hloov pauv hauv cov ntaub ntawv thoob plaws lub sijhawm, cov thermocouples yuav tsum tau ntsuas txhua hnub. Qhov kub thiab txias nyob rau hauv cov chaw cog tshuaj coal tej zaum yuav dav me ntsis, yog li txawm tias me ntsis calibration yuam kev yuav ua rau cov txheej txheem tseem ceeb. Calibration yuav tsum tau ua raws li cov lus qhia nruj thiab nrog rau kev siv rau qhov chaw ntsuas kub. Zoo li kev kho suab paj nruag, kev hloov me ntsis tuaj yeem cuam tshuam rau qhov kev ua tau zoo. Tsis tu ncua calibration ntawm cov thermocouples guarantees zoo ib yam thiab muaj tseeb kub nyeem ntawv.
Tsis tas li ntawd cuam tshuam rau lawv qhov tseeb yog lub thermocouples 'installation. Lawv txoj haujlwm hauv cov cuab yeej siv hluav taws xob yuav tsum zoo tag nrho. Piv txwv li, rau cov thee hluav taws xob boiler, piv txwv li, cov thermocouples yuav tsum tau muab tso rau hauv qhov chaw uas lawv tuaj yeem ntsuas qhov ntsuas kub ntawm cov chav lossis cov roj combustion. Yog tias lawv tau muab tso rau hauv thaj chaw tuag-ntws lossis ze ntawm qhov chaw sov, qhov ntsuas yuav raug cuam tshuam. Tsis tas li ntawd lav qhov tsim nyog rwb thaiv tsev thiab kev sib khi yuav pab kom tsis txhob poob cua sov lossis nkag ntawm cov khoom sab nraud cuam tshuam rau kev nyeem ntawv kub. Qhov no zoo ib yam li kev npaj kev sim kev tshawb fawb; kev tshawb pom zoo nyob ntawm qhov kev npaj kom raug.
Tsis tas li ntawd tseem ceeb heev yog cov thermocouples 'kev sib txuas thiab xaim. Kev cuam tshuam hluav taws xob tsawg kawg yuav tsum muaj txoj hauv kev txuas kom raug thiab kev sib txuas zoo. Electromagnetic cuam tshuam tuaj yeem cuam tshuam cov teeb liab thermocouple hauv cov chaw cog khoom siv hluav taws xob nrog rau ntau yam khoom siv hluav taws xob thiab hluav taws xob. Los ntawm kev siv cov kab hluav taws xob insulated thiab cov av tsim nyog, qhov kev cuam tshuam no tuaj yeem txo qis, yog li lav qhov tseeb kis tau tus mob ntawm qhov ntsuas kub rau kev saib xyuas thiab tswj cov tes hauj lwm.
Tsis tas li ntawd yuav tsum tau ua tsis tu ncua thermocouples tu thiab saib xyuas. Ib qho kev hloov pauv sai sai hauv cov thermocouple-xws li kev poob qis hauv lub teeb liab lub zog lossis kev nyeem ntawv kub tsis zoo- tuaj yeem pom los ntawm kev saib xyuas siab heev. Cov teeb meem zoo li no yuav tsum pom thiab kev saib xyuas ceev yuav tsum ua raws li lawv. Qhov no yuav hu rau kev txheeb xyuas qhov ntsuas ib zaug ntxiv, ntxuav lub thermocouple, lossis kho qhov tawg. Zoo li kev nyiam rau cov khoom muaj txiaj ntsig, kev saib xyuas zoo ib yam lav nws lub sijhawm ntev thiab ua haujlwm raug.
Thaum kawg, siv thee chemical thermocouples rau kev saib xyuas meej hu rau tag nrho cov tswv yim. Los ntawm kev xaiv cov khoom siv zoo tshaj plaws, tsim nyog tsim, nquag calibration, raug teeb tsa, thiab kev sib raug zoo rau kev saib xyuas thiab tu, txhua theem yog qhov tseem ceeb. Ua tib zoo saib xyuas cov ntsiab lus no tso cai rau cov nroj tsuag tshuaj tua hluav taws kom ua kom lawv cov haujlwm ua haujlwm tau zoo, ua kom muaj txiaj ntsig zoo, thiab txhim kho kev nyab xeeb los ntawm kev nyob ntawm cov ntaub ntawv ntsuas kub raug muab los ntawm thermocouples.
