Mu uinjiniya wa cryogenic, kuthamanga kwa kapangidwe sikungokhala mtengo wamba—ndi chizindikiro chofunikira cha chitetezo ndi magwiridwe antchito chomwe chimafotokoza kulimba kwa kapangidwe kake ka dongosolo lonse la nayitrogeni yamadzimadzi. Pa HL Cryogenics, timazindikira kuthamanga kwa kapangidwe kake kutengera kuphatikiza kwa kuthamanga kwa ntchito, mphamvu ya njira, ndi zochitika zolephera.
Kwa chitoliro chodziwika bwino cha cryogenic kapenaChitoliro Chotetezedwa ndi Zitsulo, kupanikizika kwa ntchito kumatha kuyambira pa mipiringidzo 3 mpaka 10, kutengera kupsinjika kwa thanki ndi kufunikira kwake pansi. Komabe, kukwera kwa kupanikizika kumatha kuchitika panthawi yoyambira, kutseka kwa valavu, kapena kusintha kwa gawo, makamaka pamene nayitrogeni yamadzimadzi imasintha kukhala mpweya.
Ichi ndichifukwa chake nthawi zonse timaphatikiza malire a kapangidwe, kuonetsetsa kuti dongosololi limakhala lotetezeka ngakhale zinthu zitavuta kwambiri.
M'ndandanda wazopezekamo
1. Zinthu Zofunika Kwambiri Zomwe Zimakhudza Kusankha Kupanikizika kwa Kapangidwe
2. Ma Code Ogwira Ntchito ndi Miyezo Yaukadaulo
3. Magawo Osiyanasiyana a Kupanikizika kwa Kapangidwe
4. Chifukwa Chake Kupanikizika kwa Kapangidwe N'kofunika Kwambiri Pakudalirika kwa Dongosolo
●Zinthu Zofunika Kwambiri Zomwe Zimakhudza Kusankha Kupanikizika kwa Kapangidwe
1. Kupanikizika Kogwira Ntchito ndi Mikhalidwe Yochokera
Kupanikizika komwe kumachokera, komwe nthawi zambiri kumachokera kuTanki Yaing'onokapena chotengera chosungiramo zinthu zambiri, nthawi zonse chimakhala poyambira. Zotengerazi nthawi zambiri zimagwira ntchito pakati pa mipiringidzo iwiri ndi khumi, koma kuthamanga kwa mpweya pansi kumatha kusintha chifukwa cha zosowa za kayendedwe ka madzi ndi kusintha kwa kutentha.
Timaonetsetsa kuti mbali zonse za makina osinthira cryogenic opangidwa bwino, mongaPaipi Yosinthasintha Yotetezedwa ndi Vacuumndi ma payipi a cryogenic, amatha kuthana ndi kupanikizika kwakukulu kuposa kupanikizika kwakukulu komwe kungatheke.
2. Kukula kwa Kutentha ndi Kusintha kwa Gawo
Pa -196°C, nayitrogeni wamadzimadzi umatha kutenthedwa kwambiri ndi kutentha komwe kumalowa. Ngakhale kutayika pang'ono kwa kutentha kungayambitse nthunzi mwachangu, zomwe zimakweza kupanikizika mkati.
Izi ndizofunikira kwambiri m'makina omwe alibe kayendetsedwe kabwino ka magawo, komwe madzi otsekeredwa amatha kukula ndikupanga kupsinjika komwe kumakhala kwakukulu kuposa momwe amagwirira ntchito nthawi zonse.
Kuti tichepetse izi, tikuphatikiza:
•Cholekanitsa Gawo Lotetezedwa ndi Vacuummayunitsi owongolera kuyenda kwa zakumwa ndi mpweya
• Cmakina olondola otulutsira mpweya ndi kuchepetsa kupanikizika
3. Kugwira Ntchito kwa Vacuum Insulation ndi Kuchepetsa Kutaya kwa Kutentha
Kukhazikika kwa kuthamanga kwa magazi kumadalira momwe munthuChitoliro Chotetezedwa ndi Zitsuloimagwira ntchito. Ku HL Cryogenics, timapanga makina athu kuti tichepetse njira zomwe kutentha kungayende, monga: Kudzera m'zothandizira ndi zipangizo, kuyendetsa magetsi Kuwala pakati pa mapaipi mkati ndi kunja Mpweya wotsalira ukuyenda mozungulira mu annular space
Timachepetsa kwambiri kuchuluka kwa mpweya woipa mwa kupeza mpweya woipa wambiri (nthawi zambiri 10⁻⁴ mpaka 10⁻⁶ mbar), zomwe zimapangitsa kuti kutentha ndi kuthamanga kwa mpweya zikhale zokhazikika.
Izi zimakhudza mwachindunji kupanikizika kwa kapangidwe komwe kumafunika poletsa kukwera kwa kupanikizika kosayembekezereka.
4. Kukhazikika kwa Vacuum Yosinthika
TheDongosolo la Pampu Yopumira Yopanda Mphamvundi kusiyana kwakukulu pakati pa machitidwe athu. Zimasunga vacuum yokhazikika pakapita nthawi.
Yankho lathu ndi losiyana ndi makina osungira mpweya omwe amawonongeka chifukwa cha kutuluka kwa madzi pang'ono kapena kulowa kwa madzi. Amayang'ana nthawi zonse kuchuluka kwa mpweya womwe uli m'malo osungira mpweya.
• Zimathandiza kuti pakhale vacuum yotayika
• Zimawonjezera moyo ndi magwiridwe antchito a dongosololi
Izi zimatsimikizira kuti chotenthetsera vacuum chimagwira ntchito mofanana nthawi zonse, zomwe zimachepetsa kusintha kwa kutentha ndikuletsa kusakhazikika kwa kuthamanga kwa mpweya m'maukonde a mapaipi akutali.
5. Kuphatikiza Zigawo ndi Kuyesa kwa Kupanikizika
Kupanikizika kwa kapangidwe kake kuyenera kukhala kofanana pazigawo zonse za dongosolo:
Vacuum Insulated Valve: Zimateteza zinthu ndipo zimaletsa kutentha kulowa.
Paipi yosinthika yotenthetsera yotenthetsera: imakulolani kuti muyipinde pamene mukusunga mphamvu mkati.
Cholekanitsa Gawo Lotetezedwa ndi Vacuum: Amasunga khalidwe la gawo ndikuletsa kukwera kwa kuthamanga kwa magazi.
Timapanga zigawo izi kuti zizigwira ntchito limodzi ngati dongosolo m'malo mwa zidutswa zosiyana. Izi zimatsimikizira kuti dongosolo lonse la nayitrogeni yamadzimadzi likhoza kuthana ndi kupanikizika kofanana.

Mwa kuphatikiza zathuDongosolo la Pampu Yopumira Yopanda Mphamvu, Vacuum Insulated ValvendiCholekanitsa Gawo, tikukupatsani dongosolo lomwe limasuntha bwino helium yamadzimadzi ndikuchepetsa ndalama.Tanki Yaing'onondiMapayipi OsinthasinthaTiyeni tigwire ntchito zonse zoyenda ndi zokhazikika molondola.
Kupanikizika kwa kapangidwe kuyenera kutsatira miyezo yovomerezeka ya uinjiniya wa cryogenic, monga: ASME B31.3 imagwiritsidwa ntchito kwambiri mu LNG ndi gasi wa mafakitale. DIN EN 13480 ndi yofala ku Europe ndi Southeast Asia. Miyezo ya ISO ya mapaipi ndi zombo zomwe zimagwira ntchito kutentha kochepa kwambiri
M'misika yolamulidwa monga zomangamanga za LNG ku Southeast Asia kapena mafakitale a gasi ku Europe, kutsatira malamulo si njira yosankha; ndi chofunikira pogula.
Timaonetsetsa kuti makina onse a HL Cryogenics akukwaniritsa kapena kupitirira miyezo iyi. Izi zikuphatikizapo kuyesa mphamvu, kutsimikizira zipangizo, ndikuonetsetsa kuti kuwotcherera kwachitika bwino.
