Watt Density Xaiv rau 400℃Cartridge rhaub: Qhov tseem ceeb rau kev ua tau zoo thiab siv tau ntev

Thaum xaj 400℃cartridge rhaub, ntau cov neeg siv khoom lag luam tsis xyuam xim rau watt ceev, tab sis tus lej no feem ntau tuaj yeem qhia tau tias lub tshuab cua sov yuav kav ntau xyoo lossis tawg hauv ob peb lub hlis. Watt ceev, uas yog ntsuas nyob rau hauv watts ib square centimeter (W / cm²) ntawm lub rhaub lub active nto cheeb tsam, ncaj qha cuam tshuam rau qhov kub thiab txias ntawm cov xov hlau sab hauv, cov hauj lwm zoo ntawm tshav kub hloov lwm lub tsev, lub uniformity ntawm kub, thiab lub rhaub lub lifespan. Yog tias koj xaiv qhov tsis raug watt ntom ntom ntawm 400 degree, koj tuaj yeem xaus nrog kev ua haujlwm qeeb thiab nkim zog lossis qhov kub kub txaus ntshai uas ua rau NiCr tsis kam xaim thiab MgO rwb thaiv tsev.

Nws yog ib qho yooj yim los xam cov mis:** Watt Density (W / cm²)=Tag nrho Watts ÷ (π × Sheath Diameter hauv cm × Heated Length hauv cm)**


Rau qhov zoo- haum hlau thaiv, qhov ntsuas kub zoo rau 400℃cartridge rhaub yog: • Tsawg: 5–10 W / cm² • Nruab nrab: 10 txog 15 W / cm²
• Siab: 15–25 W / cm² (tsuas yog muaj kev sib cuag zoo thermal thiab txaus tej khoom)
* Tsawg Watt Ceev (5-10 W / cm²)
Zoo rau cov platens loj, cov pwm tuab, cov hlau hnyav tuag, lossis cov haujlwm uas xav tau maj mam, txawm tias cua sov tsis muaj qhov kub. Cov cua sov no nyob txias dua rau sab hauv, uas ua rau qeeb oxidation thiab grain tsim nyob rau hauv cov hlau tsis kam. Qee qhov kev siv yog superplastic forming tuag, kub kub - xovxwm platens, thiab cov cuab yeej rau extruding hlau. Vim tias cov cua sov ntws maj mam los ntawm qhov loj, qhov kub sib txawv ntawm qhov thaiv kom tsis pub dhau ± 5 degree. Kev pabcuam lub neej feem ntau kav ntev dua 15,000 txog 20,000 teev, yog li qis- qhov ceev yog qhov kev daws teeb meem zoo tshaj plaws thaum ceev tsis tseem ceeb li kev cia siab.
* Medium Watt Ceev (10-15 W / cm²) **
Qhov kub zoo tshaj plaws rau feem ntau 400℃siv. Qhov ntau yam no ua rau muaj qhov sib npaug zoo ntawm cov cua kub ceev (feem ntau 30-60 vib nas this rau lub hom phiaj) thiab lub neej ntev nrog zoo sib xws. Feem ntau cov yas txhaj tshuaj pwm, kub- khiav manifolds, ntim ntim cov kab tuav, thiab cov qhov cub hluav taws xob dav dav yog tsim los ua haujlwm nrog nruab nrab watt ntom. Cov khoom siv OEMs tsim qauv ntawm no vim tias nws ua haujlwm nrog ntau hom resins (ABS, PP, PC, nylon) thiab lub sijhawm voj voog yam tsis xav tau cov cua txias ntxiv lossis cov blocks loj. Nrog rau kev txhim kho kom raug, qhov kub ntawm cov hlau sab hauv tswj kev nyab xeeb hauv qab 650 degree, uas yog qhov zoo nyob rau hauv cov kev txwv ntawm hwm NiCr 80/20 hlau thiab siab -purity MgO. Qhov no txhais tau tias cov hlau tuaj yeem ua haujlwm tsis tu ncua rau 10,000 txog 15,000 teev.
**High Watt Density (15-25 W / cm²) **
Tsuas yog rau cov me me, nyias- cov phab ntsa, ultra- cov tshuab nrawm nrawm, lossis cov ntawv thov uas qhov chaw muaj tsawg thiab cua sov yuav tsum tau ua kom muaj zog hauv thaj chaw me me. Qee qhov piv txwv yog kub- lub taub hau khiav, cov cuab yeej siv rau kev kho mob catheters, cov kab hluav taws xob semiconductor, thiab siab - ceev sealing puab tsaig. Cov cua sov no tau kub tsawg dua 15 vib nas this, tab sis lawv yuav tsum tau ua kom haum zoo nrog lub qhov 0.05-0.08 hli thiab nyob ib puag ncig los ntawm cov hlau (steel lossis tooj liab) uas ua kom sov zoo. Qee zaum, lawv kuj xav tau kev ua kom txias. Yog tias tsis muaj qhov tsis txaus, qhov ntsuas kub ntawm lub plhaub tuaj yeem mus siab dua 550℃sab hauv, txawm tias cov txheej txheem nyeem 400 degree. Qhov no tuaj yeem tawg sai sai MgO thiab hlawv nws tawm. Nco ntsoov xyuas qhov tseeb watt ntom tiv thaiv lub neej - daim duab kev cia siab los ntawm cov chaw tsim khoom. Ntau lub siab- cov neeg muag khoom kawg muab cov nkhaus uas qhia tau tias ntau tshaj 20 W / cm² hauv cov hlau ntawm 400℃txiav lub neej txoj sia los ntawm 50% lossis ntau dua.
** Yuav Ua Li Cas Xaiv Txoj Cai Watt Density **
1. Siv cov hauv qab no los xyuas seb koj xav tau hluav taws xob ntau npaum li cas:
Fais fab (W)=Mass (kg) × Tshwj Xeeb Thaum tshav kub kub (kJ/kg· degree) × ΔT (℃) ÷ Heat-up Time (s) × 1.3 kev ruaj ntseg yam.
2. Xaiv txoj kab uas hla thiab qhov ntev ntawm lub rhaub uas yuav haum rau cov duab.
3. Kom tau W/cm², faib tag nrho cov watts los ntawm qhov chaw saum npoo av.
4. Muab piv rau cov kab saum toj no thiab hloov pauv: kom txo qhov ntom ntom, nthuav qhov ntev lossis txoj kab uas hla, lossis ntxiv cov cua sov ntxiv.
**Cov lus qhia siv tau rau kev xaiv** • Cov ntaub ntawv uas tsis siv hluav taws xob zoo (xws li yas thiab ceramics) yuav tsum khaws cia ntawm lossis qis dua 12 W / cm² kom tsis txhob yaj lossis hlawv hauv ib qho chaw. • Cov hlau uas muaj kev ua haujlwm siab, xws li txhuas, tooj liab, thiab tooj dag, tuaj yeem tiv taus 15 txog 22 W / cm². • Xav tau cua sov sai? Siv qhov ceev dua, tab sis ntxiv qhov muag muag - pib ramp thiab tiv thaiv qhov kub thiab txias. • Ua haujlwm txhua lub sijhawm, 24/7? Txhawm rau kom nws kav ntev li ntev tau, tso ib qho ua tiav qhov ntom ntom (piv txwv li, siv nruab nrab es tsis txhob siab). • Nco ntsoov nug tus kws tsim khoom rau watt- qhov ceev thiab qhov kub ntawm lub neej nkhaus rau cov ntaub qhwv uas koj xav tau (304, 316L, 321, lossis Incoloy 800). • Siv ib lub thermocouple implanted los yog IR lub koob yees duab los saib xyuas cov khoom rau thawj 48 teev. Yog hais tias ib cheeb tsam yog ntau tshaj 50℃tshaj li ib txwm, nws txhais tau hais tias qhov ceev yog tawm.

Txoj cai watt ceev rau 400℃cartridge rhaub tuaj yeem txhais tau tias qhov sib txawv ntawm ib feem koj yuav tsum hloov txhua peb lub hlis thiab ib qho koj nruab thiab tsis nco qab txog ntau xyoo. Kev xaiv qhov yog ib qho ua rau muaj kev mus nrawm dua, kev tswj cov txheej txheem zoo dua (± 2-3℃stability nrog PID), 15-25% tsawg zog siv, thiab cov khoom me me ntawm cov khoom seem. Cov xwm txheej kub sib txawv, hom khoom siv, tsim cov cuab yeej siv, thiab lub voj voog ua haujlwm txhua tus xav tau watt- qhov ceev ceev uas tshwj xeeb rau lawv. Nrhiav ib lub chaw tsim khoom uas muaj ntau yam kev paub uas tuaj yeem ua lub neej-kev cia siab simulation raws li koj qhov tshwj xeeb bore haum, khoom siv, thiab lub voj voog profile. Lawv yuav muab koj qhov zoo tshaj plaws 400℃cartridge rhaub uas yog qhov ua tau zoo tshaj plaws, txhim khu kev qha, thiab tus nqi - zoo rau tus kheej.

When the watt density is just right, the heater operates cooler on the inside, moves heat precisely, and becomes the most reliable portion of your system.
