Ntev -Lub Sij Hawm Thermal Stability Comparison Ntawm Cov Kub Kub Kub Tshiab thiab Hnub nyoog
Feem ntau cov kab ntau lawm tsis quav ntsej qhov kev ua tau zoo ntawm cov khoom siv hluav taws xob laus thiab txuas ntxiv siv cov cua sov uas muaj hnub nyoog nrog cov hluav taws xob tsis zoo, ua rau lub sij hawm ntev - tawm los ntawm cov khoom iav nkhaus. Many old heaters can still heat up normally after thousands of hours of operation, but their internal radiation uniformity, power density and thermal response performance have undergone subtle attenuation. Qhov kev ua haujlwm tsis pom pom no ua rau tsis muaj qhov sib npaug ntawm cov cua sov thermal thiab tsis ruaj khov molding zoo. Kev nthuav qhia qhov kev ua tau zoo sib txawv ntawm cov cua sov tshiab thiab cov laus laus thiab tsim cov kev hloov pauv kev tshawb fawb tuaj yeem txhim kho cov khoom tsim tau zoo, thiab tuav ntev - lub sij hawm sib txuam nrog cov thermocouple kub tswj tshuab.
Qhov pom tseeb tshaj plaws ntawm kev ua haujlwm attenuation ntawm cov cua sov laus yog qhov txo qis ntawm infrared radiation uniformity. Cov kws tshaj lij cov tshuab cua sov tshiab muaj cov txheej txheem cua sov sab hauv thiab cov chaw quartz huv si, paub txog omnidirectional zoo ib yam hluav taws xob. Tom qab ntev - lub sij hawm siab - kub cyclic ua hauj lwm, hloov maj mam thermal qaug zog ua rau me ntsis hloov chaw thiab deformation ntawm cov cua sov nyob ntawm tej nyob rau hauv lub zos, uas ua rau tsis sib xws nyob rau hauv lub zos tshav kub tiam. Cov ntaub ntawv me me thiab micro- nplai carbonization txheej ntawm lub raj nplaim thaiv ib feem ntawm lub zog hluav taws xob, tsim cov cheeb tsam tsis sib xws ntawm hluav taws xob attenuation. Lub zuag qhia tag nrho thermal teb uniformity ntawm lub cub tawg kab noj hniav txo ho.
Power density attenuation and response lag are hidden aging problems that are difficult to detect. Ntev-lub sij hawm siab- qhov kub thiab txias ua haujlwm ua rau muaj qhov hloov pauv hloov pauv ntawm cov cua sov, ua rau lub zog tsis sib npaug ntawm cov raj sib txawv. Lub zog hluav taws xob hauv zos ua rau muaj cua sov tsis txaus nyob rau hauv qhov chaw ruaj khov ntawm lub tshuab hluav taws xob, tsim kom muaj qhov tsis tshua muaj siab - qhov kub thiab txias zones. Qhov nce thermal inertia ntawm cov cua sov laus ua rau qeeb qhov kub thiab txias, ua rau cov txheej txheem kub hloov pauv lag tom qab cov lus qhia hloov kho thermocouple.
Cov cua sov uas muaj hnub nyoog kuj tau txo qhov siab - qhov kub thiab txias ua haujlwm. Ntev - cov khoom siv sij hawm laus ua rau cov txheej txheem xoob me ntsis ntawm quartz raj nto, uas yooj yim rau adsorb cov pa phem thiab tsim cov txheej txheem carbonized. Lub aging sab hauv muab tub lim ua me me voids, ua rau tsis ruaj tsis khov thaum tshav kub kub conduction kev ua tau zoo. Cov kev hloov pauv kev laus no ua rau lub xeev cua sov ntawm cov cua sov qub txawv txawv ntawm cov khoom tshiab, thiab cov txheej txheem calibrated tseem tsis tuaj yeem hloov mus rau qhov ua tau zoo cua sov.
Kev kuaj xyuas lub tshuab ua kom sov tsis tu ncua thiab hloov lub voj voog tuaj yeem tiv thaiv kom tsis txhob muaj kev pheej hmoo zoo. Kev ntsuas qhov ntsuas kub thiab ntsuas hluav taws xob sib npaug tuaj yeem txiav txim siab qhov kev laus ntawm cov cua sov. Kev hloov pauv raws sij hawm ntawm cov cua sov uas muaj hnub nyoog rov ua kom pom qhov zoo tshaj plaws thermal teb lub xeev ntawm cov kab noj hniav, tshem tawm cov teeb meem batch los ntawm kev ua haujlwm attenuation.
Tshiab siab - ua tau zoo infrared tso cua sov ua kom muaj hluav taws xob zoo ib yam, lub zog teb thiab kev huv rau lub sijhawm ntev. Lub xeev cua sov ruaj khov zoo sib xws nrog cov thermocouple precision kub tswj, kom ntseeg tau ntev - lub sij hawm tus qauv thiab siab - tawm los ntawm cov iav nkhaus. Kev tswj kev laus ntawm cov cua sov yog qhov tseem ceeb rau kev ua haujlwm ruaj khov ntawm precision iav ntau lawm kab.
