Yuav txiav txim li cas seb Cartridge Heater Txhawb Lub Sijhawm Ntev-120℃Ambient Ua Haujlwm

Ntau tus neeg muag khoom tau sau cov khoom lag luam raws li "kub tsis muaj zog", tab sis feem ntau lub tshuab rhaub dej tsis tuaj yeem muaj sia nyob mus ntev-120℃cyclic ua haujlwm. Yog tsis muaj cov qauv txiav txim kom meej, cov neeg yuav khoom yuav tau txais lub tshuab rhaub dej kub uas zoo ib yam zoo ib yam tab sis tsis muaj kev hloov pauv ntawm cov khoom siv cryogenic tiag tiag. Ntau qhov ntsuas qhov ntsuas qhov ua tau zoo pab lim cov khoom tsim nyog ultra-low-temperature siv cartridge rhaub rau-120℃ua haujlwm scenarios.

Kev tshuaj xyuas qhov tshwm sim muaj cov nqi siv tsawg. Lub tshuab cua sov zoo tib yam thiab cov cua kub qis siv lub tshuab cua sov tuaj yeem sib qhia cov duab zoo sib xws, cov qauv davhlau ya nyob twg thiab qhov ntsuas qhov ntev. Sab nrauv saib tsis tuaj yeem qhia tau tias cov khoom siv sab hauv tuaj yeem tiv taus-120℃thermal shock. Qhov kev ua tau zoo tiag tiag zais hauv cov khoom siv mis thiab tsim khoom siv tes ua ntawm lub tshuab cua sov. Raws li kev paub dhau los, tsuas yog tso siab rau cov khoom lag luam daim ntawv teev npe "tso-kub resistant" yooj yim ua rau kev txiav txim siab tsis ncaj ncees lawm.

Thawj qhov ntsuas qhov ntsuas tsom rau kev teeb tsa ntawm cov cua sov sab hauv. Cartridge rhaub rau-120℃kev pabcuam xav tau cov cua sov xaim nrog qhov kub thiab txias coefficient. Cov pa nickel-chromium alloy yuav ua kom muaj qhov loj-txheej tiv taus poob ntawm-120 degree, ua rau muaj kev cuam tshuam loj heev thaum lub caij txias pib. Tsim nyog ultra-low-temperature siv cartridge rhaub txais hloov kho cua sov alloy kom txwv tsis pub tshaj tam sim no nyob rau hauv-120℃txias-xeev. Nug cov neeg muag khoom kom paub meej cov ntaub ntawv tshwj xeeb es tsis yog tsuas yog tshawb xyuas lub hwj chim ntawm lub tshuab hluav taws xob.

Rwb thaiv tsev cov ntaub ntawv thiab compaction℃ua tus thib ob tseem ceeb point. High-purity high-compacted magnesium oxide yog non-negotiable rau-120 degree-rated cartridge rhaub. Loose-filled magnesium oxide yuav ua rau sab hauv qhov khoob tom qab rov ua dua-120℃contraction-expansion cycles. Gap accumululation puas tsuaj rwb thaiv tsev qauv nyob rau hauv lub cartridge rhaub, ua rau tsis tu ncua ntawm rwb thaiv tsev tsis kam. Magnesium oxide zoo ua ke nrog cov txheej txheem compaction feem ntau txiav txim siab los tiv thaiv khaub thuas-poob kev ua haujlwm ntawm lub tshuab cua sov.

Sheath alloy qib tsis tuaj yeem hla. Standard 304 stainless hlau sheath rau lub tshuab cua sov dav hlau tsis haum rau kev txuas ntxiv-120℃raug, rau kev hloov pauv hloov pauv yuav tshwm sim nyob rau hauv qhov kub tsis tshua muaj. Tsim nyog ultra-low-temperature siv cartridge rhaub xaiv qis-temperature-tolerant alloy sheath, tuav txhua yam toughness nyob rau hauv-120 degree. Corrosive Cheebtsam nyob rau hauv qhov chaw ib puag ncig kuj yuav tsum tau ntxiv cov ntaub ntawv sheath upgrade rau cartridge rhaub.

Sealing system thiab lead-wire specification yog lwm qhov tseem ceeb ntawm kev txiav txim siab ntsuas. Cov pa ib leeg-point silicone sealing yuav poob elasticity thiab tawg ntawm-120 degree. Tsim nyog ultra-low-temperature siv cartridge rhaub txais ntau txheej txheej sealing khoom siv tes ua. Matched cryogenic-qib txhuas hlau tiv thaiv kev tawg tawg los ntawm-120℃txias poob siab. Ntau yam tsis tsim nyog hloov kho lub tshuab cua sov tsuas yog hloov cov ntaub qhwv thaum khaws cov khoom qub thiab cov hlau lead, uas tseem ua tsis tau qis dua-120℃cyclic test.

Watt density parameter yuav tsum tau kuaj xyuas. Rau-120℃trace-heating daim ntawv thov, cartridge rhaub yuav tsum khaws watt ceev nyob rau hauv 5-7 W / cm². Txawm tias cov khoom siv zoo tshaj plaws tsis tuaj yeem cuam tshuam kev puas tsuaj los ntawm kev siv watt ntau dhau. High watt ntom ntom ua rau cov thermal gradient kev nyuaj siab heev rau lub tshuab cua sov hauv txhua lub caij txias-kub. Tsis tshua muaj watt ntom ntom tsis ua kom paub qhov ntsuas kub zoo hauv qab-120℃ib puag ncig.

Cov ntaub ntawv xeem thib peb lossis cov ntaub ntawv ntsuas lub voj voog tiag tiag coj tus nqi siv tau zoo. Thov daim ntawv qhia txog lub voj voog-test simulating-120℃rau kev ua haujlwm-kub rov ua dua rau lub tshuab cua sov. Tsim nyog ultra-low-temperature siv cartridge rhaub kom ruaj khov rwb thaiv tsev tiv thaiv tom qab ntau pua lub voj voog cryogenic. Yog tsis muaj qhov tseeb qhov txias-kub lub voj voog pov thawj, cov lus piav qhia nominal-parameter tsis tuaj yeem ua pov thawj tias lub tshuab cua sov hloov mus rau-120℃tej yam kev mob.

-120 degree-theem cryogenic adaptability ntawm cartridge rhaub yog txiav txim siab los ntawm tag nrho cov khoom siv thiab khoom siv tes ua es tsis yog ib qho kev hloov kho. Thaum xaiv ultra-low-kub siv cartridge rhaub, ntau lub kaum sab xis lees paub npog cov cua sov alloy, magnesium oxide, sheath, sealing craft thiab watt ntom yog qhov tseem ceeb. Kev sib tham txog kev cai yog pom zoo rau cov haujlwm nrog kev ua haujlwm tas mus li-120 degree.
