Ceramic Terminal Ceramic Band Rhaub VS Mica Band Rhaub: Thermocouple Ntev -Lub Sij Hawm Nrawm Hauv Qhov Nruam Siab -Cycling Kub
Nruam 24-teev cov kab ntau lawm rau siab-kev ua tau zoo polymer molding feem ntau tawm tsam nrog qhov kub thiab txias me ntsis tom qab ntau txhiab lub voj voog thermal. Mica band tso cua sov ua haujlwm qis- tus nqi kev xaiv rau cov haujlwm nruab nrab kub, tsis tau thermal qaug zog degrades mica rwb thaiv tsev nyob rau hauv lub caij kub kub. Raws li kev lag luam txheeb cais, mica rwb thaiv tsev zoo li hmoov thiab poob dielectric zog siab tshaj 400 degree, qhia thermal teb distortion uas ncaj qha cuam tshuam rau qhov ntsuas qhov tseeb. Ceramic terminal ceramic band heaters tswj kev ruaj ntseg rwb thaiv tsev ua haujlwm nyob rau hauv kev kub ceev nruam kev caij tsheb kauj vab, xa cov khoom siv thermocouple rov ua tau zoo dua rau kev ua tsis tau - nres high-load thermal processing.
Mica band heaters feature txheej mica rwb thaiv tsev sandwiched ntawm cov hlau tsis kam thiab stainless hlau sheath. Lub teeb yuag thiab nyias profile suits compact tshuab chim nrog txwv radial installation qhov chaw. Tus nqi ntawm cov khoom nyob qis qis rau nruab nrab -tej txheej txheem kub. Rov ua dua thermal cycling saum 400℃ua rau mica kom lub cev qhuav dej thiab hmoov maj mam. Rwb thaiv tsev ntom ntom nti thiab cov chaw kub hauv zos tshwm sim. Thaum tshav kub kub faib hloov mus thoob lub thoob qhov chaw, yog li cov ntawv nyeem thermocouple maj mam sib txawv ntawm qhov tseeb ntawm qhov kub. Cov qauv nyias teb sai sai rau kev hloov pauv hluav taws xob, tab sis thermal runaway pheej hmoo nce ntxiv thaum rwb thaiv tsev pib degrade.
Ceramic terminal ceramic band heaters tsim cov cua sov los ntawm kev sib cuam tshuam ceramic knuckles nrog npib tsib xee-chrome alloy hlau threaded los ntawm cov kab xev ceramic. Inorganic ceramic rwb thaiv tsev tswj kev ua haujlwm ruaj khov hauv kev ua haujlwm tas li ntawm 450 degree. Rwb thaiv tsev decay tshwm sim ntawm tus nqi qeeb qeeb, khaws cia cov cua sov sib xws thoob plaws hauv lub thoob. Ruaj khov thermal teb faib txhais tau hais tias cov thermocouple sensors khaws qhov tseeb calibrated dhau lub sijhawm ua haujlwm ntev. Higher allowable surface watt density supports fast and uniform heating without localized overheating. Lub rooj sib txoos nqa ntau dua thickness thiab loj, yuav tsum tau loj dua radial clearance thiab siab dua upfront procurement nqi piv nrog mica band heaters. Rau cov haujlwm qis - kub tsis sib xws, cov peev nyiaj ntxiv tau txais txiaj ntsig me ntsis.
Cyclic aging test cov ntaub ntawv qhia meej cais ob qhov kev daws teeb meem cua sov. Mica band heaters khiav tsis tu ncua ntawm 410℃qhia tias thermocouple txhua xyoo drift ncav cuag 1.4℃tom qab 4000 thermal cycles, nrog rwb thaiv tsev hmoov pom thaum kuaj xyuas. Ceramic terminal ceramic band heaters nyob rau hauv tib lub caij tsheb kauj vab txwv cov thermocouple drift mus rau 0.35 degree. Mica band heaters ua kom txias sai dua - nqes teb vim qis thermal huab hwm coj, uas tuaj yeem pab tau rau cov txheej txheem uas yuav tsum tau rov pib dua kub sai. Ceramic terminal ceramic band heaters muaj thermal inertia loj dua, qeeb qhov kub poob qis thiab yuav tsum tau hloov kho PID tsis rau thermocouple tswj loops.
Lub sijhawm tu thermocouple txawv heev ntawm ob hom cua sov no. Mica band rhaub tshuab xav tau cov thermocouple recalibration txhua txhua 1000 mus rau 1500 teev nyob rau hauv qhov kev ua haujlwm kub tsis tu ncua -. Ceramic terminal ceramic band heater setups ncua sij hawm recalibration rau 3000 teev lossis ntev dua. Kev suav lub voj voog hluav taws xob thiab ntsuas qhov ntsuas qhov ntsuas thermocouple tuaj yeem muab tso rau hauv kev tiv thaiv kev tiv thaiv. Kev tsom xam thermal thiab thermocouple muab cov lus pom zoo pab xaiv cov khoom siv cua sov uas tsim nyog raws li kev ua haujlwm kub, lub voj voog zaus thiab muaj qhov chaw siv tshuab.
