Vim li cas Qhib -Hloov Rhaub Carbon Buildup Ua rau Thermocouple Signal Disorder & Cas Ceramic Hlau Tube Composite Heaters daws nws
Tsis tu ncua thermocouple teeb liab teeb meem thiab tsis xwm yeem kub drift yog ntawm cov teeb meem feem ntau zais hauv kev ua lag luam txuas ntxiv. Cov kab ntau ntau ntawm cov khoom lag luam siab - cov kab ntau lawm ntsib qhov kev tswj qhov kub thiab txias tsis ua haujlwm tom qab lub sijhawm ua haujlwm ntev -, txawm tias muaj qib siab - qib thermocouple sensors thiab ntse ntsuas qhov ntsuas kub nruab. Raws li kev lag luam kev txheeb cais, ntau dua 70 feem pua ntawm qhov tsis pom qhov ntsuas kub tsis ruaj khov tshwm sim los ntawm cov pa roj carbon deposition thiab oxidation ntawm qhib cua sov xov hlau nyob rau hauv ib txwm ua cua sov, es tsis yog thermocouple aging lossis system parameter yuam kev. Cov pa qhib mica tso cua sov thiab liab qab-cov khoom siv hluav taws xob ceramic tso cov cua sov ncaj qha rau huab cua, cov pa roj carbon monoxide, roj fume thiab cov plua plav, ua rau cov pa roj carbon monoxide nyob rau ntawm cov hlau. Cov pa roj carbon ntau hloov pauv hauv zos thermal kuj thiab ua rau cov cua sov tsis sib xws, cuam tshuam qhov chaw thermal ruaj khov uas yuav tsum tau ua kom raug ntsuas qhov ntsuas thermocouple.
Ib txwm liab qab-wire ceramic heaters txais segmented qhib los ua ke cov qauv uas tsis muaj kev tiv thaiv kev sib cais rau alloy cua sov xov hlau. Nyob rau hauv siab - kub thiab siab - kev ua qias tuaj ib puag ncig, cov yas pyrolysis volatiles thiab roj fume ua raws li cov cua kub ntawm cov xaim hlau thiab tsim cov pa roj carbon ntau tom qab ntev - lub sij hawm siab - kub ci. Cov pa roj carbon monoxide tsis tu ncua ua rau muaj ob qhov kev ua tsis tiav: hauv zos overheating tshwm sim los ntawm kev ua kom thermal tsis kam thiab luv luv - Circuit Court txaus ntshai los ntawm carbon conduction. Ob qho teeb meem cuam tshuam cov khoom siv hluav taws xob tsis sib xws ntawm cov cua sov thiab ua rau cov thermal field gradients tsis zoo, ua kom ruaj khov -point thermocouple sampling cov ntaub ntawv tsis sib xws thiab tsis sib xws. Lub sijhawm ua haujlwm ntev -Lub sijhawm ua haujlwm yuav ua rau cov teeb liab thermocouple jitters thiab sib txawv ntawm qhov kub thiab txias, txo cov khoom tawm los thiab nce lub sijhawm poob qis.
Mica heaters ntsib cov teeb meem zoo sib xws nrog cov tsis zoo siab - qhov kub thiab txias. Qhib cov txheej txheem cua sov tsis tuaj yeem cais cov pa phem sab nraud, thiab cov txheej txheem mica rwb thaiv tsev maj mam pulverize saum 400 degree. Qhov ua tsis tiav ntawm cov rwb thaiv tsev laus thiab xaim carbon deposition ua rau thermal teb stability tsis zoo, uas ua rau tsis tu ncua thermocouple drift uas yuav tsum tau nquag recalibration. Cam khwb cia aluminium heaters nrog ib qho kev sib khi qauv txo cov pa roj carbon deposition txaus ntshai tab sis raug kev txom nyem los ntawm siab - kub deformation thiab rwb thaiv tsev attenuation saum 420 degree, tsis ua raws li ntev - lub sij hawm siab - kub nruam ntau lawm thov rau engineering plastics.
Ceramic hlau raj sib xyaw ua kom sov ua kom tsis muaj zog qhib cua sov qauv ntawm cov khoom lag luam los ntawm txoj kev kaw hlau raj cua sov tsim. Alloy cua sov xov hlau thiab magnesium oxide insulating xov xwm tau kaw tag nrho hauv stainless hlau tubular shells, tsis muaj kev sib cuag ncaj qha ntawm cov tub ntxhais cua sov thiab ib puag ncig kev cob qhia sab nraud. Cov qauv kaw tag nrho hauv paus thaiv cov adhesion thiab tsub zuj zuj ntawm cov roj fume, plua plav thiab yas volatiles, tshem tawm cov cua sov hlau carbon deposition thiab oxidation tsis ua hauj lwm los ntawm qhov chaw. Sab nraud siab - zaus ceramic rwb thaiv tsev thav duab muaj qhov ruaj khov siab - qhov kub thiab txias thermal conduction kev ua tau zoo, ua kom ntseeg tau ntev - lub sij hawm zoo thermal field output.
Qhov chaw ruaj khov thiab huv si sab hauv cua sov ntawm cov cua sov sib xyaw muab ib qho ultra- qhov ntsuas kub ruaj khov rau lub tshuab thermocouple. Yog tias tsis muaj qhov cuam tshuam los ntawm lub sijhawm ua haujlwm los ntawm cov pa roj carbon deposition, cov ntsiab lus ntawm cov thermocouple sampling cov ntsiab lus tuaj yeem ntes cov ntaub ntawv kub thiab txias ua haujlwm tau ntev, tshem tawm cov teeb meem tsis sib haum xeeb thiab tsis sib xws. Qhov kev ua kom zoo ntawm cov qauv no zoo heev txo qhov kev ntsuas zaus ntawm cov tshuab thermocouple thiab txhim kho kev ruaj ntseg ntawm kev kaw - voj kub tswj rau cov kab ntau lawm.
A 2500-teev kev ntsuas kev ua qias tuaj tsis tu ncua sau cov pa roj carbon deposition℃ntawm plaub lub tshuab hluav taws xob thiab cov thermocouple teeb liab hloov pauv hloov pauv hauv cov roj fume thiab kub kub ua haujlwm:

Cov ntaub ntawv xeem intuitively txheeb xyuas qhov zoo ntawm kev hloov pauv ntawm ceramic hlau raj sib xyaw cov qauv hauv kev tiv thaiv -carbon deposition thiab thermal field stability. Lub kaw tubular tsim daws qhov mob tseem ceeb ntawm qhov qhib cua sov ua kom muaj kuab paug tsis ua haujlwm, ua kom zoo rau qhov chaw ua haujlwm ntawm cov ntsuas kub ntsuas thermocouple. Rau 24-teev nruam cov kab ntau lawm nyob rau hauv cov kev hloov kho plastics thiab engineering plastics, qhov kev txhim kho kev ua tau zoo no txhais tau ncaj qha rau hauv kev tsim khoom ruaj khov thiab txo cov nqi kho.
Kev sib txuam tsim nyog ntawm kev sib xyaw ua ke los tiv thaiv- cov cua sov ua pa phem thiab siab - cov khoom siv thermocouple sensors ua rau siab - kev tswj qhov kub thiab txias. Kev hloov kho cov qauv thiab ntsuas qhov ntsuas kub kom zoo raws li nyob rau ntawm -qhov chaw muaj kuab paug thiab qhov ntsuas kub tuaj yeem ua rau cov khoom siv ua haujlwm ruaj khov thiab tsis txhob muaj kev pheej hmoo zoo los ntawm qhov tsis zoo ntawm qhov chaw thermal.
