Kev Tiv Thaiv Kev Tiv Thaiv Tag Nrho: Thermocouple Signal Stability of Enclosed Heaters nyob rau hauv plua plav thiab roj Mist Industrial Environments
Hnyav rhiav ib puag ncig nrog cov plua plav hnyav, cov yas ntim thiab cov roj pos huab ua rau muaj teeb meem loj rau cov cua sov kom ruaj khov thiab ntsuas qhov tseeb ntawm cov thermocouple. Ntau qhov qhib cua sov cov ntsiab lus tau ua kom muaj kev laus zuj zus thiab qhov kub thiab txias tsis ua haujlwm hauv cov kev ua haujlwm nyuaj, txawm tias muaj kev tu thiab tu. Raws li kev txheeb xyuas kev lag luam ib puag ncig kev hloov pauv, cov qauv qhib tsis tuaj yeem thaiv cov pa phem hauv kev nkag mus rau hauv lub hauv paus, thaum cov khoom siv cam khwb cia tso siab rau kev tiv thaiv kev sib cais tag nrho kom tswj tau ultra-ruaj khov thermocouple teeb liab tso tawm nyob rau hauv siab - muaj kuab paug kev lag luam scenarios.
Qhib mica thiab ceramic heaters tau qhib cov txheej txheem rwb thaiv tsev thiab segmented splicing structures, uas ua rau muaj peev xwm nyob ib puag ncig tsawg. Nyob rau hauv extrusion thiab txhaj tshuaj rhiav nrog ntev -lub sij hawm roj pos huab floating thiab residual yas overflow, me me pa phem hais tsis tu ncua nkag mus rau hauv lub cua sov cov qauv los ntawm cov qauv sib txawv. Nyob rau hauv siab - kub ua hauj lwm, infiltrated roj thiab yas residues carbonize sai heev thiab ua raws li cov cua kub nyob ntawm tej thiab rwb thaiv tsev txheej, tsim ruaj ruaj siab - cov ntsiab lus tsis kam kub tsub zuj zuj. Qhov hloov pauv hauv thermal qauv distorts saum npoo ntawm qhov kub thiab txias, ua rau chaotic thermocouple sampling signals thiab nruam hauv paus drift.
Pollutant tsub zuj zuj nyob rau hauv qhib lug kuj ua rau hluav taws xob kev ua tau zoo attenuation. Carbonized av muaj qee yam conductivity, uas txo cov rwb thaiv tsev tsis kam ntawm cov cua sov qhib thiab ua rau muaj kev phom sij zais ntawm hluav taws xob thiab hauv zos arcing. Kev cuam tshuam me me ntawm hluav taws xob tsim los ntawm kev ua haujlwm tsis ruaj khov ntawm cov rwb thaiv tsev yuav raug ntes los ntawm siab -rhiab heev thermocouple sensors, tsim cov teeb liab tsis sib xws thiab qhov kub thiab txias yuam kev. Ntev- lub sijhawm ua haujlwm yuav ua rau cov cua sov xaim oxidation thiab hlawv, ua rau cov khoom siv kaw cia tsis ua haujlwm.
Cov cam khwb cia tso cua sov tau txais cov khoom siv hlau tag nrho - sealing qauv los tsim omnidirectional lub cev kev sib cais cov teeb meem. High- txheej txheem casting txheej txheem nruj nreem qhwv cov cua kub hauv cov xov hlau thiab cov khoom siv hluav taws xob tsis zoo hauv cov hlau matrix ntom ntom, tsis muaj qhov khoob rau cov plua plav sab nraud, cov roj pos huab thiab cov khoom seem yas rau infiltrate. Tag nrho cov pa phem tuaj yeem tsuas yog txuas mus rau sab nrauv hlau, uas tuaj yeem raug tshem tawm tag nrho los ntawm kev tu txhua hnub yam tsis muaj kev cuam tshuam rau sab hauv thermal thiab hluav taws xob cov qauv. Qhov chaw ua haujlwm ruaj khov nyob rau hauv ib puag ncig ua kom muaj lub teeb liab thermocouple raug thiab sib xws rau lub sijhawm ntev.
Environmental aging contrast cov ntaub ntawv txheeb xyuas kev tiv thaiv kev ua haujlwm tsis zoo. Tom qab 2500 teev ntawm kev ua haujlwm tas mus li hauv cov plua plav thiab cov roj pos huab ua haujlwm, qhib cov cua sov ua kom sov ua kom sov lub teeb liab ntawm 1.1℃thiab rwb thaiv tsev attenuation ntawm 17.3%. Qhib mica heaters qhia teeb liab jitters ntawm 1.5℃thiab attenuation ntawm 22.6%. Cov cam khwb cia tso cua sov tsuas yog tsim cov teeb liab jitter nyob rau hauv 0.25℃thiab rwb thaiv tsev attenuation qis dua 3.1%, tswj ua tiav hluav taws xob thiab thermal kev ua tau zoo.
Kev lag luam cua sov system stability nyob rau hauv complex rhiav nyob ntawm cov qauv ib puag ncig adaptability es tsis yooj yim txij nkawm txhua hnub. Npog tag nrho - cov qauv kev cais tawm hauv paus daws cov pa phem - ntxias cov thermocouple drift thiab khoom siv tsis ua haujlwm. Kev soj ntsuam ib puag ncig kev ua haujlwm thiab kev sib tw thermocouple tiv thaiv- cuam tshuam calibration tuaj yeem ua rau kev ua haujlwm ruaj khov ntawm cov cua sov hauv cov xwm txheej hnyav.
