{{0 {{}} j30 thiab 6J22 yog ob qho tib si ntawm {}} npib tsib xee raws li precials alloists. Dab tsi yog qhov tseem ceeb ua haujlwm sib txawv ntawm lawv?
Cov tub ntxhais sib txawv ntawm cov khoom nyob hauv lub cev nqaij daim tawv lawv tau tsim los tswj, uas hais txog lawv tag nrho cov ntaub ntawv thov.
1J30: tus tswj kev nthuav dav alloy. Qhov no alloy belongs rau lub "iav {{{}} seeding" tsev neeg. Nws lub luag haujlwm tseem ceeb yog kom muaj cov coefficient ntawm thermal expansion (CTE) uas tuaj yeem sib xws rau cov iav lossis ceramics. Qhov no tso cai rau nws los ua tus muaj zog, airtight) Foob uas yuav tsis tawg los yog xau thaum lub khob nthuav dav thiab cog lus ntawm yuav luag tus nqi sib npaug.
6J22: ib qho kev hloov pauv tas mus li (Elinvar - hom). Qhov no alloy txoj kev txhais cov yam ntxwv yog qhov ruaj khov ntawm nws cov modulus loj heev (cov tub ntxhais hluas tus modulus) tshaj qhov ntau qhov kub. Rau feem ntau cov hlau, txhav txo li kub nce siab. 6 J22 yog lub caij nplooj ntoo hlav lossis cov khoom siv hluav taws xob zoo ib yam tsis hais txog qhov kub hloov chaw.
Hauv ntej: 1j30 tswj hwm thermal nthuav; 6j22 Kev tswj kub {}}} inducts txhav txhav lug.
2. Rau cov ntawv thov tshwj xeeb twg yuav tus tsim qauv engineer xaiv ib qho 1j30 lub raj hla lwm cov alloys zoo li 4J42?
Nws xaiv 1J30 (feem ntau ~ 29% ni) tshaj 4J42 (~ 42% ni) yog qhov tshwj xeeb tsis yog- nws yog xim hlau siv.
Sib txuam cov khoom lag luam nthuav dav (1j30 muaj CTE qis dua li 4J42. Nws yog tshwj xeeb xaiv rau kev sib khi nrog qee lub tsom iav alleasilate iav lossis siab {{alumina ceramics uas tseem muaj qhov qis qis dua thermal nthuav dav. Siv cov expansion ntau zoo li 4j42 yuav tso lub khob lossis tej hub nyob rau hauv cov kev ntxhov siab tensile ntxhov siab thaum txias.
Daim ntawv thov tseem ceeb:
High - h siab lossis siab - Lub raj muaj hluav taws xob rau cov tshuab hluav taws xob rau cov tshuab hluav taws xob lossis lub nqus tsev yog huab. Qhov zoo meej CTE phim kom tau lub foob lub meej mom nyob rau hauv cov kev ntseeg no.
Aerospace sensors: hauv vaj tse rau cov sensors uas muaj kev kub ntxhov, ib qho kev sib tw sib sau ua ke nrog cov nyom uas muaj kev sib raug zoo los tiv thaiv kev tiv thaiv sab nrauv hluav taws xob.
Cov khoom siv hluav taws xob tshwj xeeb hluav taws xob: qee hom microwave leeg lossis lwm yam CTE cov khoom siv uas muaj cov ntaub ntawv zoo tshaj plaws rau cov ntaub ntawv direa-as.
Qhov kev xaiv yog qhov kawg sau los ntawm cov ncauj lus piav qhia cte kev txheeb xyuas ntawm ob lub hlau thiab cov khoom siv insulating thoob plaws.
3. Lub tubular daim ntawv yog qhov tseem ceeb rau ntau daim ntawv thov. Cov kev ua tau zoo ntawm 6j22 raj ua li cas thiaj zoo rau siv rau hauv high {4} precing acension thiab sij hawm ua haujlwm?
Kev sib xyaw ntawm 6j22 alloy tus constant modulus cov cuab yeej thiab cov geometric efficiency ntawm lub raj tsim cov kev sib xyaw ua ke nrog kev ua tau zoo.
Lub sijhawm ruaj khov ntawm cov neeg muaj zog: hauv cov khoom siv xws li kev ua kom nruj (rau kev ntsuas ntoj nti), lossis lub sijhawm ua haujlwm ncaj qha rau cov ntawv square ntawm cov khoom siv ntawm cov khoom siv me me. Txij li thaum modulus ntawm 6j22 yog tas li nrog qhov kub thiab txias, tus neeg uas yog ib zaus ntawm lub raj ua los ntawm nws tseem nyob ruaj khov. Qhov no tsis tsim nyog nrog cov qauv cov ntaub ntawv, uas nws cov zog yuav drift nrog qhov kub hloov pauv.
Kev siab siab thiab ua tau zoo: lub raj, ua hollow, muaj lub siab tawv tawv {{0} {1} qhov hnyav. Thaum siv raws li lub caij vibrating nyob rau hauv ib lub sensor, nws tuaj yeem tsim kom muaj kev nkag siab sab nraud (xws li loj cuam tshuam los ntawm qhov kub thiab txias, uas yog thawj qhov yuam kev.
Precision caij nplooj ntoos hlav Hais zoo li Electromagnetic Force Rebalometers lossis Gradeete lossis Caij Nplooj Ntoos Hlav Los Yog Qhov Tseem Ceeb. Cantilevered 6j22 raj tuaj yeem ua raws li cov pivot no. Nws lub ntsej muag txhav tas li kom cov ntsuas hluav taws xob {}} Qhov chaw nyob rau ntawm lub cev loj- seem muaj qhov tseeb ntawm nws lub hnab ntawv nyhav.
4. Dab tsi yog qhov kev sib tw tseem ceeb hauv machining thiab vuam 1J30 thiab 6j22 hlab, thiab lawv ua li cas lawv txawv ntawm kev ua qauv stainless hlau hlab?
Ua cov ntaub ntawv no yuav tsum tau sib tw metallurgically - х }្ approach,, raws li cov qauv kab teeb meem tau yooj yim ua rau lawv cov txiaj ntsig zoo precement cov khoom.
Machining cov nyom:
Ua haujlwm tawv tawv: ob qho tib si alloys, tshwj xeeb yog lub nickel - nplua nuj 1j30, muaj feem xyuam rau kev ua haujlwm sai sai thaum lub sijhawm txiav lossis khawb. Qhov no yuav tsum siv cov ntse, zoo - rake carbide cov cuab yeej, thiab ntau dua cov kev txiav tawm mus rau "tau txais" cov tawv tawv. Ample coolant yog qhov tseem ceeb.
Discensional stability (1J30): Kev sib tw qhia txog kev ntxhov siab, uas tuaj yeem ua rau muaj lub sijhawm 1j30 ua rau muaj sijhawm los yog kev kho cua sov tom ntej. Kev ntxhov siab {{5 5}}} ann relief្ ann reliefing at at at low at at atនing at mayនing may tsawg yuav raug muab ntawm machining cov kauj ruam.
Tswj kev kho cua sov (6j22): 6j22 tau txais nws cov peev ntawm ib qho preception precipitation {4 {4 4 {} tawv kho kom sov. Machining feem ntau yog ua nyob rau hauv softer "tov"-} {{{{{{} qhov kawg {ua kom tiav. Yog tias machining yuav tsum tau tshaj tawm - {} {{} {tawv}} haj} {tawv tawv kom tsis txhob muaj kev cuam tshuam saum npoo av.
Vuam cov nyom:
Hloov cov khoom hauv Weld Cheeb Tsam: VUAM VUAM TSHWJ XEEB yog rau cov khoom tseem ceeb. Lub khaus, nyob rau hauv cov tshav kub hauv zos hloov kho microstructure los ntawm tshav kub - beurive cheeb tsam (Haz).
Rau 1J30, lub cheeb tsam weld yuav muaj cov CTE sib txawv, ua rau muaj kev ncaj ncees ntawm cov iav txuas ntxiv ntawm {- hlau foob.
Rau 6J22, lub cheeb tsam weld yuav tsis teb kom raug rau lub hnub nyoog- tawv tawv} qhov chaw mos, qhov chaw tsis muaj zog nrog ib qho tsis sib xws nrog cov modulus tsis zoo.
Yog tias vuam yog unavoidable: roj tungsten arc vuam (gtaw / tig) hauv kev tswj cov khoom siv hlau yog yuav tsum tau ua. Qhov no yuav tsum tau ua raws li ib daim ntawv tag nrho?
5. Hauv tus nqi -}} {{22 raj {{5}- Lub zog caij nplooj ntoos hlav steel raj?
Qhov kev ncaj ncees rau 6j22 lus dag nkaus hauv cov kab ke uas tus nqi ntawm kev ua haujlwm drift lossis calibration yuam kev dhau tus nqi ntawm cov khoom ntawm cov khoom nws tus kheej.
Kev tshem tawm ntawm qhov ntsuas kub uas tau them nyiaj: lub zog siv tus txheej txheem hluav taws xob hlau sib zog yuav tsum muaj kev cuam tshuam nrog lub caij nplooj ntoo hlav hloov pauv txhav txhav. Siv lub 6j22 raj tau txais kev tshem tawm qhov ua yuam kev no, yooj yim rau cov qauv tsim, txhim kho kev ntseeg tau, thiab txo cov nqi calibration.
Ntev -}} TIB ruaj khov thiab txo cov nqi sib cav: cov twj uas siv rau peb cov tseem ceeb lossis cov ntsiab lus tseem ceeb kom lawv qhov tseeb ntau qhov kub thiab txias ntau. Qhov no yog qhov tseem ceeb rau kev ua teb {{4 4}}}, geophysical sensors system) qhov twg tsis tu ncua yog impractical lossis tsis yooj yim sua. Qhov siab dua thawj cov khoom siv tau raug nqi yog amortized dhau ib lub neej ntawm ruaj khov, tsawg- kev ua haujlwm.
Txhim kho kev ua tau zoo hauv cov neeg siv khoom sib txawv: xws li siv cov khoom siv hauv lub hnab ntawv (piv txwv li kev ua haujlwm siab
Qhov kev txiav txim siab yog kev lag luam classic - tawm: kev nqis peev ntawm cov khoom sib luag Nyob rau hauv lub terse siab tshaj plaws ntawm precision engineering, tus qub yog feem ntau yog cov tsuas yog xaiv tau.
