Kev Tsim Nyog Ua Haujlwm Tom Qab Txhim Kho Cov Cuab Yeej Cuab Yeej ntawm -196 degree

Nws tsis yog tshwm sim tias qee yam ua haujlwm zoo ntawm -196 degree. Cartridge rhaub ua rau cov kev pabcuam cryogenic txawv ntawm cov khoom lag luam niaj hnub vim lawv tau tsim thiab ua nrog qee yam nta thiab kev tswj xyuas. Paub txog cov txheej txheem thev naus laus zis no pab koj sau thiab siv cov lus qhia kom raug.

Lub hauv paus ntawm cov ntaub ntawv tshawb fawb qhia kev tsim cov cua sov cryogenic. Austenitic stainless hlau muaj lub ntsej muag -centered cubic crystal lug uas tsis tawg yooj yim ntawm qhov kub thiab txias. Nickel-raws li alloys yog lwm qhov kev xaiv rau cov ntawv thov uas yuav tsum tau tswj qhov kub thiab txias. Cov ntaub ntawv tiv thaiv hlau yuav tsum ua kom lawv cov kev tiv thaiv thiab cov khoom siv zoo ruaj khov txawm tias qhov kub hloov pauv ntau.


Rwb thaiv tsev system engineering deals nrog cov teeb meem nrog dielectrics. Magnesium oxide yog cov khoom siv hluav taws xob zoo sib xws, tab sis nws yuav tsum tau ua tiav txawv rau kev siv hauv ib puag ncig cryogenic. Lub zog dielectric ntawm qhov kub tsis tshua muaj kev cuam tshuam los ntawm qhov loj ntawm cov nplej, qhov ntom ntom ntawm cov compaction, thiab cov dej noo hauv huab cua thaum lub sij hawm tsim khoom. Kev ua haujlwm tshwj xeeb ua kom cov rwb thaiv tsev nyob ruaj khov thaum cov khoom siv tsis tu ncua.

Tswj thermal expansion yog ib feem loj ntawm kev tsim cryogenic. Kev sib txawv ntawm cov ntaub qhwv, rwb thaiv tsev, thiab cov khoom tiv thaiv induces internal stresses. Coil winding txoj kev, kev txhawb nqa cov qauv, thiab qhov kawg foob tsim tuaj yeem ua rau qhov loj me tsis cuam tshuam rau lub zog hluav taws xob lossis lub zog.

Foob thev naus laus zis yog ib txoj hauv kev tseem ceeb heev los qhia cov khoom sib nrug. Ntawm qhov kub thiab txias, cov txheej txheem epoxy lossis silicone seals tau ua nyuaj thiab tawg. Iav-rau-cov ntsaws ruaj ruaj hlau, cov ntsaws ruaj ruaj tshwj xeeb ceramic, los yog tsim cov ntsaws ruaj ruaj kom cov foob pob hluav taws tsis zoo. Tus qauv tsim ntawm lub foob yuav tsum coj mus rau hauv tus account ob qho tib si thermal cycling thiab ntev - lub sij hawm raug rau cryogenic tej yam kev mob.

Kev tswj hwm hauv cov txheej txheem tsim khoom kom paub tseeb tias lub hom phiaj tsim tau ua tiav hauv thaj chaw. Lub rooj sib txoos huv si zam cov kab mob uas tuaj yeem ua rau txoj hauv kev hluav taws xob lossis cov pa tawm hauv cov ntawv thov hoover. Cov txheej txheem tshwj xeeb vuam txuas cov ntaub ntawv sib txawv yam tsis tau ua cov txheej txheem intermetallic nkig. Kev ntsuam xyuas thaum lub sijhawm ua haujlwm xyuas cov txheej txheem tseem ceeb ua ntej cov cua sov tawm hauv lub hoobkas.

Cov ntawv pov thawj zoo rau cov kev pabcuam cryogenic mus dhau tsuas yog kuaj xyuas cov tshuab hluav taws xob. Cryogenic immersion test, thermal cycling validation, thiab thermal shock test tag nrho sim ua raws li cov xwm txheej tiag tiag hauv ntiaj teb. Cov txheej txheem txheeb cais tswj xyuas qhov muag ntawm kev tsim khoom zoo li cas. Traceability systems khaws cov ntaub ntawv ntawm cov ntaub ntawv thiab cov txheej txheem siv nyob rau hauv txhua batch ntawm ntau lawm.

Daim ntawv thov engineering txuas yam uas tuaj yeem tsim nrog yam xav tau hauv thaj chaw. Kev sib tham txog kev hloov qhov system xav tau rau hauv cov cua sov specifications. Cov lus qhia rau kev txhim kho tham txog tej yam tshwj xeeb rau cryogenics. Kev pab daws teeb meem siv kev paub los ntawm kev tsim khoom los kho cov teeb meem hauv thaj chaw.

Kev paub dhau los yog siv rau hauv kev tsim cov evolution ntawm cov txheej txheem kev txhim kho tas mus li. Kev tshuaj xyuas qhov ua tsis tiav ntawm cov cua sov rov qab qhia tau tias qhov twg yuav txhim kho. Cov ntaub ntawv tshiab thiab cov txheej txheem txhim kho kev ua haujlwm. Cov neeg siv khoom tawm tswv yim pab peb txiav txim siab seb yuav ua li cas ua ntej.
