Transmission Electron Microscope Seals

Transmission electron microscope (TEM) seals ua lub luag haujlwm tseem ceeb hauv kev tswj hwm lub tshuab nqus tsev ib puag ncig siab, ua kom cov qauv ruaj khov, thiab tiv thaiv cov khoom tseem ceeb ntawm cov cuab yeej. Nov yog qee cov ntsaws ruaj ruaj hauv kev sib kis hluav taws xob microscopy thiab lawv cov yam ntxwv:

Sample tuav seals

Txoj hauj lwm thiab kev ua haujlwm

Nyob rau ntawm qhov sib txuas ntawm tus qauv tuav thiab lub microscope lub cev. Tus qauv tuav yog ib qho khoom siv los nqa thiab thauj cov qauv hauv lub tshuab kuaj kab mob, thiab lub luag haujlwm tseem ceeb ntawm tus qauv tuav lub foob yog txhawm rau tiv thaiv cov pa tawm sab nraud los ntawm kev nkag mus rau hauv lub tshuab nqus tsev siab ntawm lub tshuab nqus tsev los ntawm tus qauv tuav, kom tswj tau cov pa roj carbon monoxide. stability ntawm lub tshuab nqus tsev ib puag ncig. Yog tias muaj teeb meem nrog cov qauv bar foob, nws tuaj yeem ua rau txo qis hauv lub tshuab nqus tsev, cuam tshuam rau kev sib kis ntawm cov kab hluav taws xob thiab cov duab zoo.

Khoom siv

Nws feem ntau yog ua los ntawm roj hmab, PTFE, thiab lwm yam ntaub ntawv uas muaj elasticity zoo thiab sealing. Cov ntaub ntawv no muaj peev xwm tuav tau zoo sealing zog thaum lub sij hawm tso thiab rho tawm ntawm tus qauv tuav thiab kuj yuav tsum muaj ib co hnav thiab corrosion kuj kom tau raws li qhov yuav tsum tau ntawm kev siv mus sij hawm ntev.

Dewar cov ntsaws ruaj ruaj

Txoj Haujlwm thiab Kev Ua Haujlwm

Nyob rau hauv TEM cryogenic qauv tuav system, lub dewar yog siv los khaws cov tub yees los muab ib qho chaw cryogenic, thiab dewar foob yog nyob rau ntawm qhov sib tshuam ntawm dewar thiab cov cryogenic conduction los ua ke. Nws txoj haujlwm yog los xyuas kom meej tias cov tub yees tsis xau, kom ntseeg tau tias kev ua haujlwm ib txwm muaj ntawm cov txheej txheem cryogenic, thiab tiv thaiv cov pa tawm sab nraud los ntawm kev nkag mus rau dewar thiab cuam tshuam rau kev ua haujlwm ntawm cov tub yees.

Khoom Khoom

Vim tias qhov yuav tsum tau ua haujlwm nyob rau hauv ib puag ncig uas tsis muaj qhov kub thiab txias, cov khoom ntawm dewar foob yuav tsum muaj cov khoom zoo uas tsis muaj qhov kub thiab txias, xws li kev tuav elasticity thiab nruj ntawm qhov kub thiab txias. Cov khoom siv feem ntau suav nrog cov khoom siv roj hmab tshwj xeeb lossis cov khoom siv polymer, uas tau raug kho tshwj xeeb lossis tsim kom tau raws li cov kev xav tau ntawm kev ua haujlwm kub.

Lens fwj seals

Txoj hauj lwm thiab kev ua haujlwm

Nyob rau hauv lub lens chim ib feem ntawm kis tau tus mob electron microscope, nrog rau qhov chaw uas cov khoom tseem ceeb xws li phom electron, condensers, thiab lub hom phiaj lo ntsiab muag. Lub luag haujlwm ntawm lub lens fwj foob yog cais tawm sab hauv ntawm lub lens chim los ntawm ib puag ncig sab nraud, tswj lub tshuab nqus tsev siab hauv lub lens fwj, thiab xyuas kom meej tias cov kab hluav taws xob tuaj yeem kis tau thiab tsom mus rau ib txwm tsis muaj kev cuam tshuam los ntawm cov pa hluav taws xob sab nraud.

Cov yam ntxwv ntawm cov khoom

Feem ntau, kev sib xyaw ua ke ntawm lub nplhaib hlau sealing lossis roj hmab sealing nplhaib thiab cov qauv hlau yog saws. Cov hlau foob muaj lub zog siab thiab nruj, thiab tuaj yeem tiv taus lub tshuab nqus tsev siab hauv lub lens fwj; Roj hmab foob muab kev them nyiaj zoo dua elastic kom haum rau me me thiab deformations ntawm lub tog raj kheej thaum lub sijhawm teeb tsa thiab siv.

Rooj vag valve seals

Txoj hauj lwm thiab kev ua haujlwm

Nruab ntawm lub tshuab nqus tsev vacuum valve ntawm kis tau tus mob electron microscope. Lub tshuab nqus tsev vacuum valve yog siv los tswj lub hauv / tawm ntawm lub tshuab nqus tsev, thiab thaum lub rooj vag valve raug kaw, lub qhov rooj valve foob tuaj yeem tiv thaiv huab cua los ntawm lub tshuab nqus tsev los yog lub tshuab nqus tsev vacuum, kom ntseeg tau tias lub tshuab nqus tsev ib puag ncig ntawm lub tshuab nqus tsev ua haujlwm sib txawv.

Khoom siv

Nws feem ntau yog ua los ntawm cov roj hmab lossis cov ntaub ntawv yas uas tiv taus hnav, kub thiab siab, thiab yuav tsum muaj kev ua haujlwm zoo elastic rov qab los xyuas kom meej tias lub rooj vag valve tseem tuaj yeem tuav tau zoo sealing nyhuv tom qab ntau yam kev hloov pauv.
