Zowumitsa Zozizira Zambiri

Mwachidule za Zowumitsira Manifold Freeze

Chowumitsira mufiriji chochuluka nthawi zambiri chimagwiritsidwa ntchito ngati chida cholowera mu kuumitsa kuzizira.Ofufuza omwe akufunafuna mankhwala omwe amagwira ntchito kapena kukonza tizigawo ting'onoting'ono ta HPLC nthawi zambiri amagwiritsa ntchito chowumitsira mufiriji nthawi zambiri poyambira mu labu.Lingaliro logula zowumitsira zowumitsira zamtunduwu nthawi zambiri zimatengera zomwe zikuphatikiza, koma sizimangokhala:

1. -Nambala ya ogwiritsa ntchito mu labu nthawi zambiri imakhala yochuluka ndipo kuchuluka kwa zinthu zomwe akupanga ndizochepa

2. -Ziwerengero zazikulu za zitsanzo zazing'ono

3. Zing'onozing'ono zipangizo bajeti

4. Ma cell banking mtundu wa malo

5. Muziundana zouma kuti musagwiritse ntchito pochita malonda pakadali pano

6. Kafukufuku woyambirira kwambiri

7. Pang'onopang'ono wovuta mankhwala processing chofunika

Ngakhale makina ochulukirapo amagulidwa ndipo ndi okwanira kugwira ntchito yomwe ilipo, ndikofunikira kumvetsetsa kuti kugwiritsa ntchito chowumitsira chowumitsira chamtundu wambiri kuli ndi malire okhudzana ndi kuyanika kozizira.Pamapeto pake wogwiritsa ntchitoyo alibe mphamvu pa kuyanika kowumitsidwa, monga momwe angachitire mu thireyi yodula komanso yovuta kapena chowumitsira shelufu.Komabe, pali masitepe omwe angatengedwe kuti apange chipambano chokulirapo pa chowumitsira chowumitsa mufiriji pomwe chidacho chikugwiritsidwa ntchito.Nkhaniyi ifotokoza njira zingapo zoyambira, zofooka zake ndi mphamvu zake komanso momwe mungachepetsere zovuta zina zomwe zingachitike pakuwumitsa kowuma.

Kumvetsetsa Magawo a Chowumitsira Manifold Freeze

Monga zowumitsira kuzizira zonse chowumitsira mufiriji chili ndi zigawo zinayi zofunika kwambiri.Izi ndi:

· Malo opangira zinthu

· Condenser

· Vuta

· Control System

Product Addition Station
Malo opangira zowonjezera ndi gawo la zida zomwe zimathandizira kuti chinthucho chikhale chowumitsira kuzizira.Pankhani ya kachitidwe kochulukira zinthu zotengera nthawi zambiri zimakhala ma flasks.Zogulitsazo zimayikidwa mu botolo ndipo nthawi zambiri zimawumitsidwa mopanda kutentha pang'ono kapena mufiriji.Tikambirana njira zoziziritsa kukhosi mozama pambuyo pake muzolemba zaukadaulo izi.

The Condenser
Condenser pafupifupi pafupifupi zowumitsira zamakono zonse zamasiku ano ndi malo okhala mufiriji omwe amayendetsa njira ya sublimation popanga

kutsitsa kuthamanga m'dera chowumitsira.Condenser imagwiranso ntchito kutsekereza chinyezi / zosungunulira ndipo potero zimawalepheretsa kupita ku pampu ya vacuum.Zowumitsira zowuma zowuma kwambiri zimaperekedwa mu "siteji imodzi"

(compressor imodzi), "masitepe awiri" (compressor awiri) kapena "masitepe awiri osakanikirana" (ma compressor awiri okhala ndi mpweya wapadera).Kutentha kwakukulu kwa kutentha kwa -48C (kwa gawo limodzi la siteji) kufika -85C (magawo awiri) si zachilendo.Machitidwe ena osakanikirana amatha kupeza kutentha kocheperako, monga -105C.Ndikofunika kumvetsetsa kuti kuthamanga kwa nthunzi pamwamba pa ayezi si njira yokhotakhota.Pamene kutentha kumatsika ndikutsika lamulo lochepetsa kubweza limagwiranso ntchito.

Vuto la System ndi Vuto la Pampu
Kuthamanga kwa nthunzi pamwamba pa ayezi pa -48C ndikofanana ndi 37.8 mT.Pa -85C ndi 0.15 mT zomwe zimatanthawuza kusiyana kwa pafupifupi 37.65

mT.Mukhoza kuona komabe kuti pansi pa -85C kutentha kwapansi kumapangitsa kuchepa kwapang'onopang'ono kwamphamvu - mu magawo khumi ndi zana a milliTorr.Zowonadi, mphamvu zambiri za nthunzi pamiyala ya ayezi zomwe zimasindikizidwa zimayima pafupifupi -80C chifukwa kutentha kocheperako kusiyanasiyana kumakhala kocheperako.

Pampu ya vacuum ya zowumitsa zambiri zowumitsidwa ndi masitepe awiri a rotary vane mafuta osindikizidwa.Mapampu a vacuum cholinga chokhacho nthawi yayitali yowumitsa ndikuchotsa mpweya wosasunthika (nayitrogeni, oxygen, carbon dioxide et al) mu chowumitsira madzi.Pochotsa mpweya wosasunthika m'dongosolo, pampu ya vacuum imathandizira kupanga chilengedwe cha sublimation ( ayezi kupita ku nthunzi popanda kudutsa gawo lamadzimadzi)

kuti zichitike.Chifukwa zowumitsa zowumitsa zowuma zimakhala ndi zotayikira (zotayikirapo - kutulutsa mpweya kuchokera ku chitsulo chosapanga dzimbiri (inde zitha kutuluka), ma gaskets, ma acrylics et al ndi kuchucha kwenikweni kwapang'ono kwamasinthidwe osiyanasiyana ndi malo mkati mwa dongosolo, monga pa vacuum chubu cholumikizira pakati. condenser ndi vacuum pump) pampu ya vacuum imayendetsedwa mosalekeza panthawi yonse yowumitsa zowumitsa.Mwachidziwitso NGATI chowumitsira kuzizira chinali chopanda kutayikira kwathunthu, pomwe pampu yotsekemera ikangotsitsa koyamba imatha kuzimitsidwa osagwiritsidwanso ntchito mpaka kumapeto.M’moyo weniweni izi sizingatheke.

The Control System
Dongosolo lowongolera zowumitsira kuzizira likukhala lofunikira kwambiri pakusiyanitsa kwa chowumitsira kuzizira kumodzi.Kuchuluka kwa makina odzichitira okha komanso kugwiritsa ntchito mwaubwenzi kumatha kusiyanasiyana kuchokera pamakina amodzi kupita ku ena.Mosasamala mtundu, tikulimbikitsidwa kuti automatic on and automatic off ndi gawo la kuthekera kwa woyang'anira.M'malo opangira ma laboratories omwe zowumitsa zambiri zimagwiritsidwa ntchito kwambiri, kuyanika ndi njira yofikira kumapeto komanso njira ina pamndandanda wautali wa njira zomwe anthu ayenera kugwiritsa ntchito kuti akwaniritse zolinga zawo.Sikuti aliyense ali katswiri wazowumitsira madzi ozizira.Kukhala ndi ntchito zozimitsa zokha kumathandizira kuwonetsetsa kuti njira zoyenera zoyambira ndi zotsekera zimagwiritsidwa ntchito kuti ziteteze chitetezo komanso moyo wautali.
