Kumvetsetsa Chikhalidwe cha Chikhalidwe

Pamaso delving mu enieni protocols kwa Kusamalira Liquid Argon, ndikofunikira kumvetsetsa momwe thupi lake lilili komanso zoopsa zomwe zimabweretsa. Argon (Ar) ndi mpweya wabwino wopanda mtundu, wopanda fungo, wosakoma, komanso wopanda poizoni. Zimapanga pafupifupi 0.93% yamlengalenga wapadziko lapansi. Kuti azinyamula ndi kuzisunga bwino, zimaziziritsidwa ku kutentha kwa cryogenic -makamaka, pansi pa -185.8 ° C (-302.4 ° F) - kuzisintha kukhala madzi.

Kutsika kochititsa chidwi kwa kutentha kumeneku ndi chiŵerengero chokulirapo chotsatira chikawomba ndizomwe zimayambitsa ngozi.

Ngozi Yowonjezera

Voliyumu imodzi yamadzimadzi imakula mpaka pafupifupi ma voliyumu 840 a gasi pa kutentha wokhazikika komanso kuthamanga. Ngati kukulitsa uku kumachitika pamalo otsekeka popanda mpweya wokwanira, kumatulutsa mpweya mwachangu, zomwe zimapangitsa kuti pakhale chiopsezo chachikulu cha kupuma. Chifukwa mpweya ndi wopanda fungo komanso wopanda mtundu, ogwira ntchito sangazindikire kuti mpweya wa okosijeni ukuchepa mpaka atachita chizungulire, chikomokere, kapena choyipa kwambiri.

Zowopsa za Cryogenic

Kuzizira kwambiri kwa madzi amadzimadzi kumabweretsa chiopsezo chachikulu ku minofu yaumunthu. Kukhudzana mwachindunji ndi madzi kapena uninsulated mapaipi ndi mavavu kungayambitse kwambiri chisanu, amene nthawi zambiri amatchedwa cryogenic kutentha. Kuwonongeka kwa minofuyo ndikwachangu komanso kozama, komwe kumafunikira chithandizo chamankhwala chapadera.

Kukongoletsa Zinthu Zofunika

Sizinthu zonse zomwe zimatha kupirira kutentha kwa cryogenic. Zitsulo wamba monga chitsulo cha kaboni ndi mapulasitiki ambiri amakhala osalimba ndipo amatha kusweka akakumana ndi kuzizira koopsa. Kugwiritsira ntchito zipangizo zoyenera zopangira zomangamanga ndizofunikira kwambiri.

Njira Zabwino Kwambiri Zogwiritsira Ntchito Cryogenic Fluid

Kusamalira Liquid Argon Pamafunika kuphunzitsidwa mwamphamvu, zida zoyenera zodzitetezera (PPE), komanso kutsata malamulo okhazikitsidwa.

Zida Zodzitetezera Pamunthu (PPE)

Ogwira ntchito kapena pafupi ndi makina a cryogenic ayenera kukhala ndi PPE yapadera yoteteza kuzizira kwambiri. Zovala zokhazikika zamafakitale ndizosakwanira.

Ndondomeko Zoyankha Mwadzidzidzi

Ngakhale kutsatira mosamalitsa machitidwe abwino, zochitika zadzidzidzi zimatha kuchitika. Dongosolo lodziwika bwino komanso loyeserera poyankha mwadzidzidzi ndikofunikira.

Kuthana ndi Kutayira ndi Kutayikira

1. Kuthawa: Chofunikira kwambiri ndicho kuthamangitsidwa kwa ogwira ntchito m'dera lomwe lakhudzidwa, makamaka malo otsika kumene mpweya wozizira ukhoza kuwunjikana.

2. Dzipatula: Ngati zingatheke motetezeka popanda kuyika pachiwopsezo, zimitsani komwe kukutulutsako pogwiritsa ntchito ma valve odzipatula mwadzidzidzi.

3. Ventilate: Yambitsani mpweya wabwino kwambiri. Musayese kuyeretsa kutaya; madziwo adzakhala nthunzi mofulumira.

4. Kuwongolera Chifunga: Kutulutsa kwakukulu kumapangitsa chifunga chowundana cha chinyezi chokhazikika kuchokera mumlengalenga. Chifungachi chimachepetsa kuwoneka mpaka ziro ndikuwonetsa malo ozizira kwambiri komanso kusowa kwa okosijeni. Pewani kulowa mu chifunga.

Thandizo Loyamba la Kuwonekera kwa Cryogenic

• Kukhudzana ndi Khungu: Osapaka zomwe zakhudzidwa. Sambani ndi madzi ofunda ochuluka (osati otentha). Pitani kuchipatala msanga. Musayese kuchotsa zovala zozizira pakhungu; tsukani ndi madzi kaye.

• Kuyang'ana Maso: Tsukani maso ndi madzi ofunda kwa mphindi zosachepera 15 ndikupita kuchipatala mwamsanga.

• Kulephera kupuma: Ngati munthu wakomoka chifukwa cha kuchepa kwa okosijeni, asunthireni ku mpweya wabwino nthawi yomweyo. Perekani CPR ngati sakupuma ndikupempha thandizo lachipatala mwadzidzidzi. Opulumutsa ayenera kugwiritsa ntchito Self-Contained Breathing Apparatus (SCBA) asanalowe mumlengalenga wopanda mpweya.

Pomvetsetsa zakuthupi, kukhazikitsa zida zolimba, kugwiritsa ntchito zida zolondola, komanso kulimbikitsa chikhalidwe chachitetezo chokhazikika, zida zamafakitale zitha kuwonetsetsa kuti zomwe amapereka komanso chitetezo chokwanira cha ogwira nawo ntchito. Njira zabwino zomwe zafotokozedwa apa zimakhala ngati dongosolo la kayendetsedwe koyenera, kuwonetsetsa kuti ntchito zikukhala zogwira mtima, zogwirizana komanso zotetezeka.

FAQs

Q1: Chifukwa chiyani mtundu wa valve womwe uli ndi "bonneti yowonjezera" uli wofunikira pa machitidwe a cryogenic?

A: Ma valve okhazikika amalephera kutentha kwa cryogenic chifukwa kuzizira kumapangitsa kuti zida zosindikizira zamkati (zonyamula) zichepetse, zimakhala zolimba, ndipo pamapeto pake zimatuluka kapena kusweka. Valavu ya bonnet yotalikirapo imasuntha chithokomiro chonyamula kutali ndi madzimadzi a cryogenic omwe akuyenda kudzera mu thupi la vavu. Mtunda umenewu umathandiza kuti mpweya wozungulira ukhale wotentha mokwanira kuti ukhale womasuka komanso kuti ukhale wotsekeka, kuteteza kutulutsa koopsa.

Q2: Ngati alamu yowonongeka kwa okosijeni imveka m'malo osungiramo, ndi chiyani chomwe chiyenera kuchitika mwamsanga?

Yankho: Chofunikira choyamba ndichoti anthu onse asamutsidwe m'deralo. Osayesa kufufuza komwe alamu amachokera popanda zida zapadera zopumira. Deralo likachotsedwa, okhawo ophunzitsidwa zadzidzidzi omwe ali ndi Self-Contained Breathing Apparatus (SCBA) ayenera kulowa m'malo kuti azindikire ndikuchepetsa kutayikira, ndikuwonjezera mpweya wabwino kuti abalalitse mpweya womwe wachotsedwa.

Q3: Kodi mapaipi a vacuum-jacketed (VJP) amasiyana bwanji ndi kutchinjiriza kwa mapaipi wamba, ndipo chifukwa chiyani amakondedwa?

A: Kutchinjiriza kokhazikika, monga thovu kapena fiberglass, kumadalira kutsekereza mpweya kapena mpweya kuti muchepetse kutentha. Pakutentha kwambiri kwa cryogenic, chinyezi chozungulira chimatha kukhazikika ndikuundana mkati mwa kutchinjiriza kokhazikika, ndikuwononga mphamvu yake. VJP imagwiritsa ntchito makhoma awiri okhala ndi vacuum yayikulu pakati pa chitoliro chamkati ndi jekete lakunja. Chifukwa vacuum ilibe mamolekyu otenthetsera, imakhala yothandiza kwambiri popewa kuphulika ndikusunga madziwo pakadutsa mafakitale.
