Qhov -Tshwj xeeb Cov Cuab Yeej Hluav Taws Xob: Yuav Ua Li Cas Ceramic Layout Txo Thermocouple Local Sampling Deviation
Cov chaw kub kub hauv zos thiab qhov tsis sib xws ntawm qhov chaw thermal yog qhov ua rau qhov tsis sib xws ntawm cov thermocouple multi-point sampling cov ntaub ntawv nyob rau hauv lub tshuab cua sov annular. Feem ntau cov tsoos sib sau ua ke ceramic rhaub tau txais cov cua sov cua sov xaim winding cov qauv yam tsis muaj kev txwv qhov chaw. Tom qab rov ua thermal expansion thiab contraction thaum pib thiab kaw lub voj voog, cov cua kub ntawm cov xov hlau maj mam hloov, sib sau los yog tsim cov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob. Cov qhov tsis sib xws ntawm qhov tsis sib xws ntawm qhov chaw tuag thiab cov cua sov ua rau muaj qhov sib txawv ntawm qhov sib txawv ntawm cov ntsiab lus thermocouple uas nyob ib sab, ua qhov tseeb tag nrho cov txheej txheem kub txiav txim tsis yooj yim sua thiab ua rau tsis sib xws ntawm cov yas yaj thiab molding zoo.
Raws li qhov kev sim ntsuas qhov ntsuas qhov ntsuas tau zoo, qhov tsis muaj qhov ntsuas cua sov xaim xaim xaim ua rau ntau dua 70 feem pua ntawm qhov ntsuas kub hauv zos tsis sib xws hauv cov pa hluav taws xob ceramic. Kev sib txuas ntawm cov hlau me me ua rau lub zog loj hauv zos los ntawm ntau dua 15 feem pua, ua rau pom qhov tsis pom qhov kub uas cov thermocouple ib leeg - taw tes kom paub tsis tuaj yeem txheeb xyuas tag nrho. Ntev- lub sijhawm ua haujlwm txuas ntxiv ua kom lub tshav kub tsis sib xws, uas ua rau qhov sib txawv ntawm qhov kub thiab txias ntawm cov kav dej txuas ntxiv thiab tsis tu ncua ntawm cov txheej txheem kev ruaj ntseg.
Plug-nyob rau hauv ceramic band heaters daws qhov tsis sib xws ntawm cov cua sov tsis xws luag los ntawm kev sib xyaw ceramic qhov txwv cov qauv. High- kub alloy cua sov xov hlau yog embedded thiab tsau nyob rau hauv precision-machined ceramic daim card slots, ua tiav tag nrho - lub voj voog txiav txim yam tsis muaj kev txiav txim siab los yog stacking. The standardized clamping structure locks wire spacing and distribution density permanently, ensuring consistent power output per unit area of the annular heating surface. Qhov kev txiav txim siab cua sov no tshem tawm lub zog hauv cheeb tsam thiab cov chaw thermal tuag, ua kom muaj kev sib luag thiab tsis tu ncua thermal teb.
Ib puag ncig zoo thermal teb zoo heev optimizes thermocouple sampling raug thiab sib xws. Txawm hais tias nruab nrog ib qho -taw tes ntsuas ntsuas kub ntsuas los yog ntau -point array ntsuas kub ntsuas tshuab, cov ntaub ntawv ntsuas ntsuas ntsuas qhov sib xws thiab rov ua dua. Tsis muaj qhov ntsuas kub hauv cheeb tsam cuam tshuam cuam tshuam nrog kev txiav txim siab, ua rau PID cov tswj ntsuas kub kom tsim tau raug kaw thiab ruaj khov- kev hloov pauv. Qhov zoo ntawm cov qauv no yog tshwj xeeb tshaj yog nyob rau hauv precision extrusion thiab micro-txhaj tshuaj molding txheej txheem rhiab rau qhov kub thiab txias sib txawv.
Ntxiv nrog rau qhov ua tau zoo ntawm cov cua sov ua haujlwm, qhov kaw qhov kho cov qauv txhim kho siab -kub hluav taws xob kev nyab xeeb. Cov kab hluav taws xob cua sov tau txwv tag nrho hauv cov txheej txheem rwb thaiv tsev ceramic yam tsis muaj kev cuam tshuam kev sib cuag, zam kev luv luv -circuit thiab leakage txaus ntshai tshwm sim los ntawm hlau adhesion thiab hloov chaw. Ntev-lub sij hawm siab- qhov kub thiab txias kev ua haujlwm ruaj khov yog qhov zoo dua, muab kev nyab xeeb dua thiab txhim khu kev qha kev ua haujlwm rau cov ntsuas kub ntsuas qhov ntsuas kub.

Cov ntaub ntawv sib piv cov qauv ua pov thawj pom tseeb qhov zoo ntawm qhov - txwv cov qauv cua sov hauv thermal teb optimization. Kev tshem tawm ntawm cov thermal field drift tshwm sim los ntawm kev xaim xaim muab ultra- ntsuas kev ntsuas ruaj khov rau cov tshuab thermocouple, txhim kho cov txiaj ntsig kev ua tau zoo.
Rau precision thermal processing scenarios uas yuav tsum tau ultra-ib puag ncig qhov kub thiab txias, kom cov txheej txheem ua kom sov ua ke nrog siab - ntom ntom thermocouple sampling layout tuaj yeem ua kom cov txheej txheem ruaj khov. Kev tshaj lij thermal teb qhov sib npaug tsim thiab ntsuas qhov ntsuas qhov ntsuas qhov ua tau zoo xa cov kev txhawb nqa kev txhim khu kev qha rau siab -kawg yas precision manufacturing.
