Indlela yokubona iDewar
Umhla: Julayi 23, 2020
Ukuqina kweDewaribaluleke kakhulu. Nakuphi na ukuvuza kunokubangela ilahleko yerhasi. Ukuba ithwala irhasi yendalo okanye irhasi enokutsha, kusenokwenzeka ukuba ibangele ingozi yogqabhuko-dubulo, ngoko ke kuyimfuneko kakhulu ekubhaqweni kokuvuza kweDewar.
Kukho iindlela ezimbini zokubonwa kweDewar, imowudi yevacuum kunye nemo yoxinzelelo elungileyo. Iidewars ikakhulu zisebenzisa imowudi yoxinzelelo olubi kunye nemowudi yokufunxa ye-helium mass spectrometer detector evuzayo ukubona ukuvuza. Isikhangeli sokuvuza se-helium mass spectrometer siqhagamshelwe kwisixokelelwano sokufunxa. Ekubeni i-HLT550 ingenayo impompo ye-foreline, inkqubo yokucoca esetyenziswe kwisiza ingasetyenziselwa njengempompo yangaphambili ye-helium mass spectrometer ukuvuza i-detector idibaniswe kakuhle kufuphi ne-air inlet (oko kukuthi, i-air inlet ye-vacuum pump set). Inkqubo yokucoca iya kuba nempompo iseti ukucoca, ngoko qhagamshela ukuhlolwa kwindawo yokungena emoyeni yempompo. Isixhobo sokubona ukuvuza sikwicala lentshukumo yokuhamba komoya, kwaye kulula ukuba nenxalenye yoxinzelelo oluyinxenye olusasazwe kwisixhobo sokuvuza, ukuze kuphunyezwe isiphumo sokubona ukuvuza.
Iitanki zeDewar ziyilelwe ikakhulu ukugcina, ukuthutha nokusebenzisa ioksijini engamanzi, initrogen engamanzi, iargon engamanzi okanye icarbon dioxide. Ngoko ke, inkqubo yayo yokubonelela ngegesi iyikhonkco ebaluleke kakhulu kwisixhobo sonke. Ngoko kufuneka zeziphi iitshekhiJianshen itankiukwenza ngaphambi kokuba zisetyenziswe? Masenze ingqayi yegentry ukuchaza ngokweenkcukacha:
1. Inkqubo yeoksijini yetanki yeDewar kufuneka ingabi nagrisi kunye nokuvuza.
2. Kufuneka siqhagamshele i-Dewar gas interface fixtures ngokuqinileyo ukuze siyisebenzise.
3. Ngaphambi kokuba usebenzise itanki ye-Dewar, qiniseka ukuba ukhangele zonke iivalve, iigeyiji zoxinzelelo, iivalvu zokhuseleko, izixhobo zevalve yetanki ye-Dewar, njl.
4. Ingqwalasela ekhethekileyo kufuneka ihlawulwe kwinto yokuba ukuba inkqubo yokubonelela ngegesi yetanki ye-Dewar isetyenziswe okokuqala okanye iphinda isetyenziswe emva kokugcinwa, kufuneka sivule iivalve zebha yebhasi kunye ne-valve ye-gas terminal okanye i-gas cutting gun nozzle, kwaye sitshintshe inkqubo kunye ne-oksijeni efanelekileyo . Kufuneka kwakhona kuqatshelwe ukuba emva kokucoca imizuzu emihlanu, vala zonke iivalve zokusetyenziswa.
