Kev ua haujlwm ruaj khov ntawm cov tshuab cua sov yog ib qho tseem ceeb rau kev tsim khoom lag luam tas mus li, thiab ib qho - cov kav cua sov uas tau xaus yog ib qho ntawm cov khoom siv hluav taws xob ncaj qha tshaj plaws hauv kev tsim khoom niaj hnub no. Kev cuam tshuam ntau ntawm cov kab ntau lawm, kev hloov pauv zoo, thiab cov khoom siv puas tsuaj tuaj yeem rov qab mus rau qhov kev xaiv tsis tsim nyog, kev teeb tsa tsis tu ncua, kev saib xyuas tsis txaus, lossis kev tswj qhov kub tsis sib haum ntawm ib qho - tas cov cua sov raj. Cov khoom no muaj nyob rau hauv qeb ntawm tubular hluav taws xob cua sov cov ntsiab lus, feem ntau yog tsim los ntawm seamless hlau sheath, siab -purity kuj cua sov hlau, compacted magnesium oxide rwb thaiv tsev txheej, thiab siab - kub sealing Cheebtsam. Tsis zoo li cov khoom siv cua sov hauv tsev, ib qho - cov kav cua sov uas tau ua tiav yog tsim los rau cov khoom siv hluav taws xob ntau, cov lus teb ceev ceev, thiab kev ua haujlwm ruaj khov hauv cov chaw muaj kev lag luam.
Cov khoom siv cua sov hauv tsev ua raws li cov qauv tsim qauv sib txawv thiab cov ntsuas kev ua tau zoo. Electric heaters for indoor use emphasize low surface temperature, quiet operation, and simple operation, with power density kept at a low level to ensure user safety. Lub tshuab hluav taws xob hauv qab cua sov tsom rau qhov loj - thaj chaw tsis sib xws thaum tshav kub kub dissipation, lub neej ntev kev pab cuam, thiab txuam nrog lub tsev thermal rwb thaiv tsev kev ua tau zoo, yuav tsum tau ruaj khov qis - lub zog tsis tu ncua. Phab ntsa- mounted boilers integrated dej cua sov, circulating pipelines, thiab kev ruaj ntseg tswj systems, precipitating zog conversion efficiency, siab tsis kam, thiab tsev neeg siv. Ib qho - xaus cua sov raj, los ntawm qhov sib piv, txais yuav ib qho -terminal wiring qauv, ua kom nkag mus rau hauv qhov chaw nqaim xws li pwm, yeeb nkab, thiab cua sov chav. Lawv muab cov cua kub siab thiab ceev ceev rau cov pa roj, kua, lossis cov khoom siv, ua rau lawv tsis muaj kev kho cua sov, cua txias tshuab, khoom siv kub thiab av noo, thiab ntim tshuab.
Cov txiaj ntsig zoo ntawm ib qho - cov kav cua sov uas tau ua tiav yog qhov zoo sib xws nrog cov kev xav tau ntau lawm. Cov txheej txheem kev teeb tsa yog ncaj nraim, tsuas yog yuav tsum tau tso ncaj qha rau hauv qhov tshwj xeeb lossis cov kav dej tsis muaj kev sib txuas lossis cov qauv sib txuas. Kev tu vaj tse nyob twj ywm yooj yim, raws li cov hlab tuaj yeem raug rho tawm ncaj qha rau kev tu, tshuaj xyuas, lossis hloov pauv yam tsis muaj kev cuam tshuam loj ntawm cov khoom siv. Cov qauv hauv cov tubular tag nrho ua kom ntseeg tau tias txawm tias cov cua sov faib rau hauv nruab nrab, tsis txhob muaj qhov kub thiab txias hauv cheeb tsam uas tuaj yeem cuam tshuam cov khoom zoo. Kub tswj precision tseem siab nyob rau hauv rated ua hauj lwm tej yam kev mob, txhawb cov txheej txheem ruaj khov. Qhov loj tshaj qhov cua kub zoo thiab optimized tshav kub conduction txoj kev ua kom kub pauv ceev, xa cov khoom siv hluav taws xob siab thiab kub ceev ceev, txhim kho ntau lawm efficiency thiab siv zog.
Txawm li cas los xij, ib qho - cov kav cua sov uas tau tas sim ua nruj me ntsis ntawm cov ntawv thov. Kev ua haujlwm ntseeg tau yog nyob ntawm kev xaiv cov khoom tsim nyog thiab tsim qauv tsim nyog. Cov ntaub ntawv yuav tsum phim cov yam ntxwv corrosion, qhov kub thiab txias, thiab qib siab ntawm qhov nruab nrab; txwv tsis pub, raj deformation, thermal qaug zog, los yog rupture tej zaum yuav tshwm sim. Excessive power density or prolonged overloading accelerates surface aging and may lead to safety hazards. Cov xov xwm cua sov yuav tsum ua kom tau raws li cov qauv teev tseg hauv cov nqe lus ntawm kev ntws, siab, kev huv, thiab tshuaj lom neeg ruaj khov. Cov kev tsis sib haum xeeb yooj yim ua rau scaling, crystallization, nag lossis daus hauv lub raj, txo cov hluav taws xob hloov hluav taws xob thiab maj mam ua rau cov cua sov. Qhov siab tshaj plaws kev khiav hauj lwm kub tsis tu ncua feem ntau nyob ib ncig ntawm 300 degree, txwv los ntawm tshav kub tsis kam ntawm cov ntaub ntawv rwb thaiv tsev thiab hlau sheath kev ua tau zoo.
Kev siv tus qauv thiab kev saib xyuas tsis tu ncua ncaj qha txiav txim siab kev pabcuam lub neej thiab kev nyab xeeb ntawm kev ua haujlwm. Cov txheej txheem kev khiav hauj lwm yuav tsum zam kom tsis txhob muaj cua sov ntev thiab cov xwm txheej dhau los uas dhau qhov kev txwv tsim. Kev xaiv cov khoom siv thiab kev teeb tsa tshwj xeeb yuav tsum ua raws li cov xwm txheej ua haujlwm tiag tiag es tsis yog qhov dav dav - lub hom phiaj kev xaiv. Kev saib xyuas kev cob qhia tau pom zoo txhua 1-2 xyoos, suav nrog kev tu kom huv ntawm cov pob zeb sab hauv, sediments, thiab cov pa roj carbon deposits kom tshem tawm cov thermal qaug zog thiab oxidative corrosion ntawm lub raj phab ntsa. Kev tshuaj xyuas kev nyab xeeb tau ua txhua txhua 3-6 lub hlis tsom mus rau kev ua haujlwm rwb thaiv tsev, kev laus hauv Circuit Court, kev pheej hmoo ntawm kev xau, thiab luv luv -circuit zais kev phom sij, ua kom muaj kev ua haujlwm tsis tu ncua thiab ruaj khov.
Thermocouple modules tsim lub hauv paus ntawm kev tswj qhov kub thiab txias rau ib leeg - cov cua kub cua sov. Raws li kev lag luam - qib ntsuas kub ntsuas nrog cov lus teb ceev ceev thiab kev ruaj ntseg siab, cov thermocouples sau cov ntaub ntawv tiag tiag - lub sijhawm kub ntawm lub raj cua sov thiab nruab nrab, hloov cov teeb liab thermal rau hauv cov teeb liab hluav taws xob rau kev xa mus rau kev tswj hwm. Qhov kev kaw no - voj kev tawm tswv yim mechanism ua rau muaj kev hloov pauv ntawm lub zog cua sov, tiv thaiv overheating, tswj qhov kub thiab txias hloov nyob rau hauv qhov zoo tagnrho, thiab ua kom muaj cua sov kom ruaj khov thiab sib xws. Raws li kev paub txog kev lag luam, kev ua haujlwm sib koom ua ke ntawm ib qho - tas cov cua sov raj thiab cov thermocouples tuaj yeem txo cov cua sov sealing tsis ua hauj lwm thiab txhim kho tag nrho cov khoom siv hluav taws xob zoo heev.
Hauv daim ntawv thov kev ntim khoom tiag tiag, cov ntaub ntawv ntim cov ntaub ntawv sib txawv yuav tsum muaj kev tswj xyuas qhov kub thiab txias, thiab cov lus tawm tswv yim thermocouple kom ntseeg tau qhov sib txuam ntawm cov khoom cua sov thiab cov txheej txheem. Kev taw qhia kev teeb tsa yuav tsum nyob twj ywm perpendicular mus rau nruab nrab ntws kom ntseeg tau tias cov cua sov sib txawv thiab tsis txhob muaj cua sov hauv zos. Surface power density must be controlled within safe limits, and overheat protection devices linked with thermocouple signals provide an additional safety barrier.
Cov xwm txheej muaj tswv yim tau lees paub tias cov tuam txhab txais kev sib koom ua haujlwm sib koom ua ke ib leeg - tas cov cua sov tub thiab cov tshuab thermocouple tau txais kev txhim kho tseem ceeb hauv kev tsim khoom thiab cov khoom tsim nyog. Cov ntsiab lus tseem ceeb suav nrog txoj kab uas hla ntawm Φ6-Φ12mm, ntev kam rau ua nyob rau hauv ± 2mm, thiab nto load optimized ntawm 4-6W / cm² yuav tsum tau ua tib zoo teeb tsa raws li kev ua haujlwm tshwj xeeb.
Qhov tseeb, ntau yam khoom siv tsis ua haujlwm pib los ntawm cov ntsiab lus tsis saib xyuas ntau dua li cov teeb meem zoo. Kev tiv thaiv kev tiv thaiv tsis tu ncua kev tswj hwm qhov muaj txiaj ntsig siab dua 50MΩ, kev tu lub sijhawm ntawm cov pa roj carbon deposits, ruaj khov nruab nrab txaus tus nqi nyob rau hauv ib tug fluctuation ntau yam ntawm ± 10%, thiab zam tsis heev startup- kaw lub voj voog tag nrho ua rau lub neej ntev kev pab cuam.
Txhawm rau kom ua tiav, daim ntawv thov txhim khu kev qha ntawm ib qho - cov kav cua sov uas tau tso tseg yog nyob ntawm kev xaiv tsim nyog, kev teeb tsa tus qauv, kev saib xyuas kev tshawb fawb, thiab kev koom tes nrog cov thermocouple kub tswj tshuab. Cov xwm txheej sib txawv hauv kev lag luam, cov qauv khoom siv, thiab cov txheej txheem kev xav tau xav tau cov kev daws teeb meem customized. Kev txhawb nqa kev tshaj lij ua kom cov tshuab cua sov ua tiav qhov ua tau zoo tshaj plaws, ruaj khov, thiab kev nyab xeeb thoob plaws ntau qhov chaw tsim khoom.
