Khoom siv thiab tsim kev xaiv rau Cartridge rhaub nyob rau hauv Xav tau dej ib puag ncig
Cov tshuab dej ua haujlwm uas suav nrog qhov kub siab, hloov pauv chemistry, tus nqi ntws siab, lossis kev ua haujlwm tas mus li tso qhov kev xav tau ntawm cov cua sov. Cov txheej txheem txheej txheem feem ntau ua pov thawj tsis txaus thaum corrosion, nplai, lossis thermal stress ua kom degradation. Cartridge heaters muab cov qauv tsim tsim nyog los daws cov teeb meem no los ntawm kev xaiv cov khoom siv ceev faj, lub zog ceev, thiab kev tsim kho.
Lub tshuab hluav taws xob lub tshuab hluav taws xob tsim hluav taws xob los ntawm cov coil tiv thaiv thiab hloov nws los ntawm kev sib cog lus magnesium oxide rwb thaiv tsev rau cov hlau tiv thaiv. Hauv kev xav tau kev pabcuam dej, lub tshuab hluav taws xob tuaj yeem raug teeb tsa rau kev tso dej ncaj qha nrog cov khoom sib khi lossis rau kev ntxig rau hauv lub thermowell. Sheath alloys raug xaiv raws li dej chemistry: stainless hlau 316 suits feem ntau cov txheej txheem dej, thaum siab dua - alloy cov ntaub ntawv hais txog kev txhoj puab heev lossis siab - kub. Qhov chaw thau khoom feem ntau nyob nruab nrab ntawm 5 thiab 10 watts ib square centimeter rau static immersion thiab tuaj yeem nce hauv kev yuam kev.
Qhov tseeb, kev sib cuam tshuam ntawm cov ntaub qhwv thiab dej chemistry txiav txim siab ntev - lub sij hawm corrosion kuj. Chloride-muaj lossis siab- cov dej huv huv yuav xav tau cov hlau tshwj xeeb lossis kev kho saum npoo kom tiv thaiv pitting lossis kev ntxhov siab- corrosion cracking. Scale nyiam kuj cuam tshuam rau kev xaiv tsim. Cov dej tawv txhawb cov ntxhia deposition uas ua raws li thermal barrier; xaiv lub cartridge rhaub nrog polished sheath nto thiab ua ke nrog kev kho dej kom tsim nyog ua rau cov txheej txheem no qeeb.
Watt- xaiv qhov ceev yuav tsum suav rau ob qho tib si thaum tshav kub kub- hloov pauv thiab txwv cov khoom siv. Higher densities accelerate heat-up but elevate sheath temperatures, increasing the risk of film boiling or accelerated aging if fluid movement is insufficient. Flow- pab tsim qauv uas coj cov dej hla lub tshuab rhaub dej kub kom tshem tawm cov cua sov thiab nthuav dav lub zog siv tau. Thermowell mounting cais cov ntsiab lus los ntawm cov txheej txheem kua, simplifying cov ntaub ntawv compatibility thaum tseem tso cai npaum conduction los ntawm lub qhov dej phab ntsa.
Raws li daim ntawv thov cov ntaub ntawv, lub davhlau ya nyob twg sealing thiab kev tsim kho tshuab ua rau muaj kev ntseeg siab nyob rau hauv tas li - lub luag haujlwm ib puag ncig. Cov dej noo nkag thaum lub sij hawm thermal cycling tuaj yeem saturate rwb thaiv tsev thiab ua rau cov khoom siv hluav taws xob sab hauv. Hermetic seals lossis thermowell cais tawm tiv thaiv txoj hauv kev no. Kev vibration- tiv taus cov coj thiab ruaj ntseg tsis tau thermally haum rau mounting kev npaj chaw nyob expansion thiab mechanical zog uas muaj nyob rau hauv industrial chaw.
Cov txheej txheem yuav tsum sib txawv nrog cov dej muaj pes tsawg leeg, qhov kub thiab txias, cov yam ntxwv ntws, thiab lub voj voog ua haujlwm. Kev cob qhia tshwj xeeb ntawm cov khoom siv lub tshuab rhaub dej kub, watt ntom ntom, txoj kev sib khi, thiab kev teeb tsa kev teeb tsa uas suav nrog cov hloov pauv no ua rau cov kev daws teeb meem cua sov uas muaj peev xwm ua tau raws li qhov xav tau ntawm txhua qhov dej ua haujlwm - daim ntawv thov cua sov.
