Kupanikizika koyenera kwa kapangidwe ka mizere yotumizira nayitrogeni yamadzimadzi nthawi zambiri kumakhala pakati pa PN16 ndi PN40 (pafupifupi 1.6 mpaka 4.0 MPa), koma izi zitha kusintha kutengera momwe makinawo adakhazikitsidwira, momwe amagwirira ntchito, komanso malire achitetezo. Kuti titsimikizire chitetezo komanso kudalirika kwa nthawi yayitali, timasankha kuthamanga kwa kapangidwe komwe kuli kokwera nthawi 1.5 mpaka 2 kuposa kuthamanga kwakukulu kogwirira ntchito pamafakitale ambiri, monga momwe ASME B31.3 kapena EN 13480 imafunira.
Mu uinjiniya wa cryogenic, kupeza mphamvu yoyenera ya kapangidwe sikuti kumangotsatira malamulo okha; kumakhudzanso chitetezo, magwiridwe antchito a kutentha, komanso mtengo wa moyo wa makinawo. Timaganiza za mphamvu ya kapangidwe ka makina ku HL Cryogenics ngati chisankho chomwe chimaganizira zinthu zosiyanasiyana, monga mawonekedwe amadzimadzi, kusintha kwa mphamvu, ndi momwe makinawo adzagwiritsidwire ntchito.
Makina a nayitrogeni wamadzimadzi nthawi zambiri amagwira ntchito pa mphamvu zochepa mpaka zochepa (0.2–1.6 MPa). Komabe, zinthu zosakhalitsa monga kuyambitsa pampu, kutseka ma valve, kapena zochitika zotulutsa mpweya zimatha kuyambitsa kukwera kwa mphamvu. Ichi ndichifukwa chake sitimapanga zinthu kutengera mphamvu yogwiritsira ntchito yokha; m'malo mwake, timaphatikiza machitidwe a dynamic system mu mawerengedwe athu.
M'ndandanda wazopezekamo
1. Zinthu Zofunika Kwambiri Zomwe Zimakhudza Kupanikizika kwa Kapangidwe
2. Magawo Osiyanasiyana a Kupanikizika kwa Kapangidwe
3. Zigawo za Dongosolo Zomwe Zimakhudza Kapangidwe ka Kupanikizika
4. Ntchito Zogwiritsidwa Ntchito M'mafakitale Ndi Zigawo Zonse
●Zinthu Zofunika Kwambiri Zomwe Zimakhudza Kupanikizika kwa Kapangidwe
1. Zosintha ndi Kupanikizika Kogwira Ntchito
Chiyambi chake ndi mphamvu yayikulu kwambiri yomwe ikuyembekezeka kugwiritsidwa ntchito. Koma tiyeneranso kuganizira za:
Kupanikizika pa kutulutsa kwa pampu
Pakagwira ntchito mwachangu ma valve, kuthamanga kumakwera.
Kuwonjezeka kwa kutentha m'malo otsekedwa
Mu dongosolo lopangidwa bwino losamutsa cryogenic, zinthuzi zimatha kukweza kuthamanga kwamkati ndi 30% mpaka 50% kuposa momwe zinthu zilili.
2. Kulamulira Kutaya kwa Kutentha ndi Kuteteza Vacuum
A Chitoliro Chotetezedwa ndi ZitsuloZimaletsa kutentha kulowa, zomwe zimachepetsa kuwira kwa nayitrogeni. Koma ngakhale kutentha pang'ono kumatha kuyambitsa nthunzi m'malo ena, zomwe zimakweza kuthamanga kwa mpweya mkati mwa dongosolo.
Ichi ndichifukwa chake magwiridwe antchito a vacuum insulation amagwirizana mwachindunji ndi kukhazikika kwa kuthamanga kwa mpweya. Machitidwe athu ku HL Cryogenics apangidwa kuti achepetse kutuluka kwa kutentha, zomwe zimapangitsa kuti kusintha kwa kuthamanga kwa mpweya kukhale koyenera.
3. Kusankha Zinthu ndi Kukhazikika kwa Kapangidwe
Kusankha zitsulo zosapanga dzimbiri monga SS304 kapena SS316 ndikofunikira kwambiri pachitoliro cha cryogenicmakina. Zipangizozi zimasunga mphamvu ya makina kutentha kochepa ndipo zimagwirizana ndi miyezo ya ASME ndi EN.
Kupanikizika kwa kapangidwe kuyenera kugwirizana ndi:
- Makhalidwe ololedwa a kupsinjika pa kutentha kwa cryogenic
- Kuwerengera makulidwe a khoma pa khodi iliyonse
- Kukana kutopa kwa nthawi yayitali
●Mapangidwe Abwino a Kupanikizika ndi Ntchito ya Ukadaulo wa Vacuum pakukhazikika kwa Kupanikizika

ZathuDongosolo la Pampu Yopumira Yopanda Mphamvukuonetsetsa kuti:
- Magawo okhazikika a vacuum pazaka zambiri zogwirira ntchito
- Magwiridwe antchito ogwirizana a kutentha
- Kuchepa kwa chiopsezo cha kukwera kwa kuthamanga kwa magazi chifukwa cha kutentha komwe kumalowa
Izi zimathandiza mwachindunji kuchepetsa kupanikizika kwa kapangidwe kake komanso kuchepetsa chitetezo.
●Zigawo za Dongosolo Zomwe Zimakhudza Kapangidwe ka Kupanikizika
Vavu yokhala ndi Vacuum Insulation
A Vacuum Insulated Valvendikofunikira kwambiri poletsa kuyenda kwa madzi komanso kuteteza kutentha kuti kusatuluke. Kapangidwe koyipa ka ma valavu kangapangitse kuti kutentha kukhale kotentha, zomwe zingayambitse kupangika kwa nthunzi m'malo osiyanasiyana komanso kukwera kwa mphamvu.
Timapanga ma valve kuti:
Pitirizani kugwiritsa ntchito vacuum
Kutaya kutentha kochepa
Onetsetsani kuti njira yoyendetsera kayendedwe ka madzi ikugwira ntchito bwino popanda kuyambitsa kugwedezeka kwa mpweya.
Cholekanitsa Gawondi Vacuum Insulation
Kuyenda kwa magawo awiri ndi vuto lalikulu mu dongosolo lililonse la nayitrogeni yamadzimadzi. Cholekanitsa magawo chotsukira vacuum chimatsimikizira kuti madzi okha ndi omwe amafika kwa wogwiritsa ntchito womaliza ndipo nthunzi imasungidwa bwino.
Izi zimasiya:
Kuyenda kosakhazikika Kusintha kwa kuthamanga kwa magazi Miyeso yolakwika
Mwa kusunga gawo lokhazikika, timasunga kuthamanga kwa makina ndi magwiridwe antchito ake kukhala okhazikika.
●Mkhalidwe Weniweni wa Uinjiniya

Kugwiritsa ntchito nayitrogeni kochepa chifukwa cha kutenthetsa bwino
●Mafunso Ofunsidwa Kawirikawiri
Kuyambira mu 1992, HL Cryogenics yakhala ikugwira ntchito yokonza ndi kupanga mapaipi okhala ndi vacuum yambiri komanso zida zina zothandizira, zopangidwa kuti zikwaniritse zosowa zosiyanasiyana za makasitomala. Tili ndi ziphaso za ASME, CE, ndi ISO 9001, ndipo tapereka zinthu ndi ntchito kumakampani ambiri odziwika padziko lonse lapansi. Gulu lathu ndi loona mtima, lodalirika, komanso lodzipereka kuchita bwino kwambiri pa ntchito iliyonse yomwe tikuchita.
