-120 digiri mphika ozizira msampha Chiyambi
Msampha wozizira wamtundu wa mphika ndi kachipangizo kakang'ono kozizira kwambiri kotentha kwambiri, komwe kamakhala koyenera kuchitira zinthu zosiyanasiyana monga kutsekereza vacuum kuzizira msampha, kuyesa kwamafuta a biochemical, kusamba kwamadzi otsika, kugwidwa kwa gasi, ndi kuyanika mankhwala.
Mfundo ndi kugwiritsa ntchito cryogenic cold msampha
Msampha wozizira ndi msampha womwe umatchera mpweya ndi condensation pamalo ozizira.Ndi chipangizo chomwe chimayikidwa pakati pa chidebe cha vacuum ndi mpope kuti chitenge mpweya kapena kutsekera mpweya wamafuta.
Chipangizo chomwe chimagwiritsa ntchito njira zakuthupi kapena zamankhwala kuti zichepetse kupanikizika pang'ono kwa zigawo zovulaza mu gasi ndi nthunzi osakaniza zimatchedwa msampha (kapena msampha).
mwachidule
Kuthamangitsidwa mwachangu kwa chipinda chopangiramo, ndi mphamvu ya nthunzi yamadzi, ndikofunikira kwambiri kuti mugwiritse ntchito bwino pakupaka filimu yopyapyala.
Kuthamanga "kuzizira" kumafupikitsa nthawi yozungulira
Kupopa bwino kwa nthunzi wamadzi (mphamvu yozizirira)
mwachangu defrost
Chiyambi cha makina ozizira kwambiri otsika kwambiri:
Makina ozizira ozizira kwambiri otsika kwambiri amatengera kompresa imodzi ndi firiji yachilengedwe ya cascade.Mipikisano yosanganikirana yogwirira ntchito sing'anga imazindikira kutsika pakati pa chigawo chapamwamba chowira ndi chigawo chotsika chowira kudzera mu njira yolekanitsa zachilengedwe ndi masitepe ambiri, ndikukwaniritsa Tengani cholinga cha kutentha kwambiri.
Mfundo yogwiritsira ntchito:
M'malo otsekemera kwambiri pomwe pampu yotulutsa mafuta imagwiritsidwa ntchito, pali mpweya wina wotsalira, wopitilira 80% womwe ndi nthunzi wamadzi, nthunzi wamafuta ndi nthunzi ina yotentha kwambiri, koma kuthekera kwake kochotsa gasi wotsalira ndikochepa. , nthawi ndi yaitali, ndi otsala Gasi amakhalanso gwero la kuipitsa workpiece, zomwe zimakhudza kutulutsa ndi khalidwe la mankhwala.Pampu ya cryogenic trap ndiyo yabwino kwambiri yothetsera vutoli.
Mfundo yogwirira ntchito ya mpope yogwira nthunzi yamadzi: ikani koyilo yafiriji yomwe imatha kufika pansi -130°C mu chipinda chopumuliramo kapena doko la mpope wa pampu yolumikizira mafuta, ndipo mwachangu gwirani mpweya wotsalira mu vacuum system kudzera pakutsika kwa kutentha kwapamtunda kwake.Potero kufupikitsa kwambiri nthawi vacuuming (akhoza kufupikitsa nthawi kupopa ndi 60-90%), ndi kupeza malo oyera zingalowe (digiri vacuum akhoza ziwonjezeke ndi theka dongosolo la ukulu, kufika 10-8Torr, 10ˉ5 Pa).
1. Msampha wa nthunzi wa madzi:
Firiji koyilo yake nthawi zambiri anaika pakati pa valavu mkulu ndi zingalowe chipinda kapena mu chipinda zingalowe, chapamwamba ndi m'munsi zipinda za mapindikidwe ❖ kuyanika, etc. Ndi oyenera nthawi pamene outgassing wa zinthu TACHIMATA monga pulasitiki otsika kutentha. zokutira ndi coil zokutira ndi zazikulu.Koyiloyo iyenera kukhala ndi chipangizo chotenthetsera komanso chowotcha, kuti koyiloyo ibwererenso kutentha kwanthawi zonse isanatsegule chitseko nthawi iliyonse, kuti koyiloyo isatengeke ndi nthunzi wambiri wamadzi kuchokera mumlengalenga ndi chisanu. zidzakhudza vacuuming yotsatira.
2. Cryogenic cold msampha:
Ikani pa doko la mpope la pampu yotulutsa mafuta, pansi pa valavu yayikulu.Ntchito yake yayikulu ndikuletsa mafuta kuti asabwererenso ku mpope wothira mafuta, ndipo nthawi yomweyo, amatha kufulumizitsa kuthamanga kwa kupopa ndikuwonjezera kuchuluka kwa vacuum.Popeza dongosolo lili mu vacuum state, palibe defrosting chipangizo chofunika.
Awiriwo akhoza kuikidwa mosiyana kapena nthawi imodzi monga momwe akufunira.
Makhalidwe abwino kwambiri:
1. Kuthamanga mwachangu kwa madzi ndi nthunzi yamafuta kumatha kufupikitsa nthawi yopopa ndi 60-90%
2. Wonjezerani mphamvu yopangira makina anu a vacuum ndi 20% mpaka 100%
3. Sinthani mawonekedwe a zokutira, onjezerani kumamatira kwa filimuyo komanso kuthekera kwa zokutira zamitundu yambiri
4. Kuzizira kofulumira, kuzizira mpaka -120°C mkati mwa mphindi zitatu, mpaka -150°C
5. Mphindi 2 za mpweya wotentha wotentha, kubwereranso kutentha, mphindi 5 kuti muzizire
6. Chipangizo chimodzi chimatha kupanga zotulutsa ziwiri zonyamula katundu
7. Compressor yotumizidwa kunja, refrigerant yosakanikirana ndi chilengedwe
8. Ndi mawonedwe awiri a katundu ndi kutentha kwa kunja, kuwonetsera kutentha kwapafupi
9. Pamene kutentha kwa standby kufika, padzakhala kuwala kosonyeza kuti kukhoza kuyamba kuzizira
10. Kutulutsa kwa kompresa ndikokwera kwambiri, kupanikizika ndi chitetezo chambiri
Msampha wozizira kwambiri wotentha kwambiri, msampha wozizira wa vacuum, msampha wozizira wa nayitrogeni wamadzimadzi, msampha wozizira wa cryogenic.
Zida zotentha kwambiri zotsika kwambiri monga mabafa amadzimadzi a cryogenic.Zamgulu chimagwiritsidwa ntchito m'mabungwe kafukufuku sayansi, mayunivesite, ndege, biopharmaceuticals, zamagetsi, processing zitsulo ndi mafakitale ena.
-135 madigiri otsika kwambiri kutentha poto ozizira msampha
Cold trap processing ndi chipangizo chozizirira chomwe chimagwiritsidwa ntchito kusonkhanitsa zinthu mkati mwa malo ena osungunuka.Ikani chubu chofanana ndi U mufiriji, pamene mpweya umadutsa mu chubu chofanana ndi U, chinthu chomwe chimakhala ndi malo osungunuka kwambiri chimakhala madzi, ndipo chinthu chokhala ndi malo otsika osungunuka. sewera mbali yolekanitsa.
Ndi -135°C poto-mtundu ozizira msampha ndi yaing'ono kopitilira muyeso-otsika kutentha kuzizira zipangizo, amene ali oyenera zolinga zosiyanasiyana monga Parylene vacuum TACHIMATA msampha ozizira, biochemical mafuta kuyesa, otsika kutentha njira, kusonkhanitsa mpweya kusonkhanitsa, mankhwala amaundana-kuyanika, etc. The kukula kwa msampha ozizira ndi njira refrigeration akhoza payekha makonda malinga ndi zosowa wosuta.
Gwirani mpweya wamadzi ndi mpweya woipa wotulutsidwa mu bokosi lowumitsira vacuum kapena chipangizo cha decompression, sinthani magwiridwe antchito a vacuum system, muchepetse kwambiri kuchuluka kwa pampu ya vacuum, ndikutalikitsa moyo wautumiki wa pampu ya vacuum.
Kutentha kwa msampha wozizira kumawonetsedwa pa digito, komwe kumakhala koyenera kudziwa nthawi yoyambira pampu ya vacuum ndikuletsa chinyezi chomwe chili m'mipope kuti chisalowe mu mpope.
Tanki yozizira ya msampha imapangidwa ndi zitsulo zosapanga dzimbiri 304, zomwe zingagwiritsidwe ntchito poyesa madzi ndi ethanol.Atakhala okonzeka ndi galasi condenser, angagwiritsidwe ntchito poyesera asidi-based ndi zosungunulira organic.
Malo ogwiritsira ntchito
Kupaka vacuum, chithandizo chapamwamba, optoelectronics, aerospace, quartz crystal, machubu osonkhanitsa dzuwa, mabungwe ofufuza asayansi, biopharmaceuticals, makampani opanga mankhwala, mafakitale amagetsi.
