Material Performance & Thermocouple Service Life Matching of Stop Flange Cartridge Heaters
Kev sib koom ua ke nres flange molding txheej txheem thiab cov ntaub ntawv sheath ntawm ib zaug -kawg cartridge tso cua sov txiav txim siab cov qauv kev ruaj ntseg thiab thermal qaug zog tsis kam ntawm cov cua sov hauv lub sijhawm ntev - lub sijhawm ua haujlwm cyclic, thiab txuas ntxiv cuam tshuam rau lub neej kev pabcuam thiab kev ceev ceev ntawm kev txhawb nqa thermocouple systems. Ntau tus neeg siv tsis quav ntsej txog qhov sib txawv ntawm cov khoom siv hluav taws xob nres flange thiab ua tib zoo siv cov qauv sib xyaw ua ke ntawm cov thermocouple, uas ua rau muaj kev ua haujlwm tsis zoo ntawm lub neej thiab kev ua haujlwm ntxov ntxov ntawm qhov chaw ua haujlwm sib txawv. Qhov tseeb, 304 stainless hlau, 321 thermal fatigue resistant stainless hlau thiab 316L corrosion-resistant stainless steel nres flange heaters muaj qhov sib txawv siab -kub oxidation tsis kam, thermal voj voog stability thiab ib puag ncig adaptability, yuav tsum tau sib txawv thermocouple qib sib piv kom ua rau tag nrho cov kev pab cuam lub neej ntawm cua sov tshuab.
304 stainless hlau nres flange tso cua sov yog cov qauv tsim rau sab hauv tsev qhuav thiab huv si precision cua sov xwm txheej. Cov cuab yeej siv hluav taws xob sab hauv tsev, cov khoom siv ntsuas kub tsis tu ncua thiab cov khoom siv hluav taws xob cov khoom siv cua sov ua haujlwm nyob rau hauv qhov chaw nyob ruaj khov yam tsis muaj roj corrosive, roj pos huab thiab nquag kub kub caij tsheb kauj vab . 304 stainless hlau muaj qhov sib npaug siab - kub oxidation kuj thiab cov txheej txheem rigidity, thiab cov kev sib xyaw ua kom tsis txhob muaj cua sov los yog qhov sib txawv ntawm qhov kub thiab txias. Lub npoo du thiab huv si muab cov khoom siv hluav taws xob ruaj khov rau cov pa K- hom thermocouples, kom ntseeg tau ntev - lub sij hawm ruaj khov sampling teeb liab tso zis thiab tsis muaj qhov pom tseeb tseeb attenuation nyob rau hauv lub tsim kev pab cuam lub neej.
321 titanium-stabilized stainless hlau nres flange rhaub yog tshwj xeeb tshaj yog optimized rau thermal voj voog nquag hloov chaw ua hauj lwm. Automated pwm ua cov cuab yeej xav tau qhov kub thiab txias tsis tu ncua hloov pauv nrog cov khoom tsim khoom, thiab cov khoom siv cua sov ua rau ntau txhiab tus mob khaub thuas thiab kub hloov pauv txhua xyoo. Ordinary 304 stainless hlau yog feem ntau ua rau thermal qaug zog kev nyuaj siab nyob rau hauv flange hlws ris, uas ua rau micro- tawg thiab cov txheej txheem loosening tom qab ntev - lub sij hawm ua hauj lwm . 321 stainless hlau zoo inhibits intergranular thermal qaug zog puas tsuaj, tswj qhov tseem ceeb ntawm cov txheej txheem nruj ntawm lub flange tom qab kev sib hloov, thiab lub cev tsis zoo. tshwm sim los ntawm structural micro-deformation. Sib piv kev qaug zog-hloov J- hom thermocouples tuaj yeem hloov pauv mus rau qhov kub thiab txias thiab tswj xyuas qhov tseeb kom ruaj khov.
316L qis- cov pa roj carbon stainless hlau nres flange tso cua sov yog tshwj xeeb rau cov chaw ua haujlwm ntub dej thiab corrosive me ntsis. Kev cob qhia ntau lawm yog yooj yim eroded los ntawm dej vapor, txiav cov kua roj pos huab thiab kab acidic tshuaj. Ordinary stainless hlau flanges thiab raj lub cev yuav maj mam tsim oxidation corrosion thiab scaling, ua rau muaj zog hauv zos thermal kuj thiab tsis sib xws thaum tshav kub kub dissipation . 316L molybdenum- stainless hlau muaj superior corrosion kuj thiab noo noo tsis kam, ua rau lub sheath thiab flange nto du mus ntev. Kev kaw tag nrho los tiv thaiv-corrosion thermocouples yuav tsum tau muab tso rau hauv ib puag ncig zoo li no los tiv thaiv kev sojntsuam corrosion thiab sampling distortion los ntawm ib puag ncig muaj kuab paug.
Cov ntaub ntawv kuaj kev laus cov ntaub ntawv qhia tau hais tias cov khoom siv hluav taws xob tsis sib haum thiab cov qib tiv thaiv thermocouple yuav ua rau 35% mus rau 55% txo qis kev pabcuam lub neej ntawm tag nrho cov txheej txheem. Kev sib koom ua ke ntawm cov khoom siv tuaj yeem synchronize lub neej kev pab cuam ntawm cov khoom cua sov thiab cov khoom siv thermocouple, zam ib leeg - cov khoom tsis ua haujlwm ua rau tag nrho lub cev kaw.
