Micro-Gap Oxidation Failure: Yuav Ua Li Cas Thermocouple Precision Temperature Lock Avoids Heater Internal Oxidation Aging
Internal micro-gap oxidation yog qhov zais tsis ua haujlwm ntawm lub tshuab cua sov uas nyuaj rau kev kuaj xyuas txhua hnub, thiab nws maj mam ua rau lub rhaub hluav taws xob txo qis thiab qhov kawg burnout nyob rau hauv ntev - lub sij hawm siab - kub ua hauj lwm. Cov qhov khoob me me uas tsis tsim nyog tsim nyob rau hauv cov txheej txheem cua sov coil thiab cov txheej txheem rwb thaiv tsev thaum lub sijhawm tsim khoom yuav ua rau qeeb oxidation cov tshuaj tiv thaiv nyob rau hauv ntev - lub sij hawm siab - kub aerobic ib puag ncig. Oxidation cov khoom ua rau muaj kev tiv thaiv sab hauv, ua rau cov cua sov tsis sib xws thiab tsim cov chaw kub hauv zos. Feem ntau cov teeb meem kev laus no yog vim li cas cov cuab yeej siv tsis tau, thaum lub hauv paus ua rau nyob rau hauv ntev - lub sij hawm me ntsis dhau - kub ua hauj lwm yam tsis muaj kev txwv qhov kub thiab txias. Thermocouple precision kub locking tshuab nruj me ntsis txwv lub rhaub ua haujlwm kub nyob rau hauv qhov chaw nyab xeeb, inhibiting micro-kawg oxidation kev nce qib thiab ncua ntev - lub sij hawm cua sov kev ua tau zoo attenuation.
Sab hauv micro-gap oxidation mechanism txawv ntawm cov pa oxidation puas tsuaj. Sab nraud sheath oxidation tsuas yog cuam tshuam rau kev hloov pauv ntawm tshav kub thiab qhov chaw tiav, thaum lub hauv paus coil micro-gap oxidation ncaj qha puas tshav kub- tsim cov qauv. Qhov me me ntawm qhov sib txawv ntawm cov xaim hloov pauv thiab nruab nrab ntawm cov coils thiab cov hmoov rwb thaiv tsev khaws cov cua thaum lub sij hawm sib sau ua ke. Nyob rau hauv qhov siab tsis tu ncua - kub cua sov siab tshaj 450℃, cov pa seem seem reacts nrog npib tsib xee-chromium alloy xov hlau los tsim cov oxide ntom ntom. Cov sediments no sau micro qhov tsis sib haum, ua rau muaj kev tiv thaiv hauv cheeb tsam thiab ua rau muaj kev kub ntxhov nyob rau hauv ib nrab coil seem.
Ntev -lub sij hawm me ntsis tshaj - kub yog qhov tseem ceeb inducement ntawm oxidation ceev. Cov txheej txheem tswj qhov kub thiab txias tso cai rau 5℃mus rau 10℃qhov kub thiab txias hloov pauv, uas zoo li tsis tsim nyog rau cov txheej txheem molding tab sis ua kom nrawm rau sab hauv oxidation cov tshuaj tiv thaiv. Tshuaj tiv thaiv ceev ntawm hlau oxidation nce exponentially nrog kub nce. Ntev- lub sijhawm ua haujlwm ntawm marginal tshaj -kub lub xeev ua rau micro- qhov sib txawv oxidation sib sau ua ke sai, ua rau maj mam txo qis ntawm cov cua sov hauv ib mus rau ob xyoos. Kev hnyav oxidation yuav ua rau lub hauv paus coil overheating thiab rwb thaiv tsev carbonization, ua rau lub rhaub tsis ua hauj lwm tam sim ntawd.
Thermocouple siab -kev tswj xyuas qhov ntsuas qhov tseeb tshem tawm qhov qis dua - qhov kub thiab txias zais qhov phom sij. Kev ua haujlwm siab -rhiab heev thermocouple sensors tswj pwm kub hloov pauv hauv ± 1 degree, zam kom tsis txhob ntev -lub sijhawm ua haujlwm ntab ntawm qhov siab - qhov ntsuas kub. Kev ruaj khov thiab ultra- qhov kub hloov pauv qhov kub ib puag ncig txo qis hauv oxidation cov tshuaj tiv thaiv kev ua haujlwm, ua rau qeeb qeeb ntawm cov oxide sediments hauv lub tshuab cua sov micro. Precise kub txwv fundamentally suppresses pom kev laus los ntawm micro oxidation.
Kev khiav hauj lwm kub sib txawv muaj qhov sib txawv oxidation aging speeds. Cov cua sov ua haujlwm qis dua 350℃tau qeeb heev hauv oxidation kev nce qib, nrog rau kev ua haujlwm ruaj khov rau ntau tshaj peb xyoos. Ua hauj lwm kub ntawm 350℃thiab 500℃accelerates oxidation obviously, yuav tsum stricter thermocouple kub locking tsis. Siab-kub ua haujlwm siab tshaj 500℃xav tau kev hloov kho los tiv thaiv- oxidation coil cov ntaub ntawv thiab ultra-paj thermocouple kaw- voj tswj kom offset ceev oxidation aging.
Oxidation aging tuaj yeem txiav txim siab thiab kwv yees los ntawm cov ntaub ntawv hloov pauv ntawm thermocouple. Cov cua sov nrog micro oxidation sab hauv yuav pom qhov kub nce qeeb, nce lub zog tuav lub sij hawm thiab ua kom ruaj khov - lub xeev hloov pauv ntau yam. Ntev -Lub sij hawm taug qab thiab kev soj ntsuam ntawm cov kev hloov pauv ntawm cov thermocouple nkhaus tuaj yeem txiav txim siab oxidation aging degree, paub txog kev ceeb toom ntxov thiab kev tiv thaiv kev tiv thaiv ua ntej kev ua haujlwm attenuation cuam tshuam rau kev tsim khoom.
Tsim nyog standby qhov kub thiab txias ntxiv txo oxidation tsub zuj zuj. Cov kub standby siab dhau lawm thaum lub sij hawm tsim khoom ua kom tsis tu ncua siab - qhov kub thiab txias oxidation ib puag ncig, thaum kub qis heev ua rau rov qab thermal shock. Thermocouple ntse standby qhov ntsuas kub ntsuas qhov ntsuas qhov ntsuas qhov ntsuas qis qis - zog tiv thaiv - oxidation pib, ntsuas cov cuab yeej standby kev nyab xeeb thiab tiv thaiv - laus thov.
Micro- qhov sib txawv oxidation tiv thaiv qhov nruab nrab ntawm cov thermocouple precision qhov ntsuas kub xauv daws qhov zais ntev -cov teeb meem kev laus ntawm cov khoom siv hluav taws xob. Ultra- qhov kub thiab txias ua haujlwm ib puag ncig inhibits oxidation cov tshuaj tiv thaiv sab hauv, tuav ntev - lub sij hawm ua kom sov lub zog thiab kev tsim hluav taws xob ua kom sov, thiab ua kom tiav tag nrho - lub neej voj voog tus nqi ntawm cov khoom siv cua sov.
