Cov txheej txheem Swaging - Qhov pom tsis pom uas cais qhov zoo ntawm qhov tsis ua tiav

Thaum ib lub taub hau hluav taws xob cua sov tube ua tsis tiav ntxov, qhov kev xav feem ntau yog liam rau cov ntaub ntawv. Tab sis raws li kev tsim khoom, qhov tseem ceeb tshaj plaws uas txiav txim siab seb lub tshuab cua sov tuaj yeem ua haujlwm tau 650℃tsis yog qhov kev xaiv hlau ib leeg - nws yog ib qho yooj yim, deceptively theem hauv cov txheej txheem ntau lawm: swaging.

Cov txheej txheem tswj cov tshuab compression no yog cov kauj ruam tseem ceeb tshaj plaws hauv kev ua lub tshuab cua sov. Nws transforms ib tug xoob los ua ke ntawm Cheebtsam mus rau ib tug robust, functional thermal system. Txawm tias qhov zoo tshaj plaws alloys thiab cov ntaub ntawv purest yuav ua tsis tau thaum ntxov yog tias lawv tsis raug swaged.

Txoj kev taug pib nrog kev sib dhos. Lub raj hlau sheath tuav lub coiled tsis kam xaim meej- feem ntau nickel-chromium (NiCr) lossis hlau-chromium- txhuas (FeCrAl) alloy- ntawm nws qhov chaw. Qhov chaw annular yog ntim nrog magnesium oxide (MgO) hmoov, cov khoom siv ceramic paub txog nws cov hluav taws xob rwb thaiv tsev. Nyob rau theem no, lub rooj sib txoos tsis muaj zog thiab thermally inefficient. Lub MgO yog xoob thiab granular, ntim nrog huab cua khoob uas ua raws li thermal insulators. Cua yog ib tug tsis zoo conductor ntawm tshav kub, yog li cov cua kub los ntawm powered kauj yuav daig, ua rau lub coil overheat thiab hlawv yuav luag tam sim ntawd.

Swaging daws qhov teeb meem existential. Lub raj sib dhos yog rub los ntawm ib ntu ntawm cov me me tuag los yog thawb radially nyob rau hauv siab. Qhov kev ua haujlwm no tas mus li txo cov sheath sab nraud thiab siv cov compression zoo heev rau cov ntsiab lus hauv. Cov hmoov MgO xoob yog crushed ua ke rau hauv ib qho khoom, ntom, cohesive ceramic loj.

Kev hloov pauv muab peb cov txiaj ntsig sib cuam tshuam tseem ceeb rau kev ua haujlwm siab - kub:

Maximized Thaum tshav kub kub hloov.Thaum lub MgO compressed, lub insulating huab cua qhov khoob raug tshem tawm, ua rau cov hmoov txaj ho denser. Dense MgO dhau los ua qhov zoo tshaj plaws ntawm cov cua sov. Qhov no tsim kom muaj kev ua tau zoo, qis - txoj kev tiv thaiv tshav kub kom taug kev los ntawm liab - kub coil mus rau sab nrauv, qhov twg nws tuaj yeem hloov mus rau qhov chaw ua haujlwm. Rau siab -kev ua tau zoo 650℃cartridge rhaub, qhov zoo tshaj plaws ncej-swage MgO ntom feem ntau tshaj 3.5 g / cm³- tus qauv uas lav qhov kev ua haujlwm zoo thermal thiab ruaj khov.

High Dielectric zog.Ntawm 650 degree, qhov kev pheej hmoo ntawm hluav taws xob tsis ua haujlwm yog qhov tseem ceeb. Compacted MgO muab siab dielectric zog uas tiv thaiv hluav taws xob tam sim no los ntawm arcing los yog to los ntawm lub siab -voltage kauj mus rau hauv av sheath. Lub rwb thaiv tsev ua ib yam nkaus thiab ntom, tsim ib qho kev ruaj khov uas tseem muaj zog txawm tias nyob rau hauv qhov kub thiab txias hloov ceev thiab muaj zog hluav taws xob.

Txhim kho Mechanical Integrity.Swaging ua kom ntseeg tau tias cov khoom siv sab hauv nyob twj ywm kom zoo thiab txhawb nqa thoob plaws hauv lub tshuab cua sov lub neej kev pab cuam, txo qhov kev pheej hmoo ntawm kev sib txuas xoob lossis coil hloov pauv los ntawm kev vibration lossis thermal cycling.

Qhov feem ntau ua rau ua tsis tiav thaum ntxov hauv lub tshuab cua sov yog qhov tsis sib xws, uas tshwm sim raws li cov ntsiab lus luv luv, qhov ua txhaum hauv av, lossis qhib circuits sai. Advanced manufacturers employ sophisticated techniques such as hot-cold bidirectional compression to achieve the precise density and uniformity required for reliable 650℃operation. Qhov sib txawv ntawm lub tshuab hluav taws xob swaged thiab tsis yog -swaged cartridge rhaub tsis yog tsuas yog qhov kev nyiam ntawm kev tsim khoom xwb- nws yog qhov sib txawv tseem ceeb uas txiav txim siab seb lub tshuab cua sov puas muaj sia nyob lossis ua tsis tiav hauv qhov kev pabcuam kub siab -.
