Posankha payipi ya cryogenic, muyenera kuganizira mosamala momwe kutentha kwake kumagwirira ntchito, kuchuluka kwa kupanikizika, komanso momwe imagwirizanirana bwino ndi dongosolo lanu. Kuti muwonetsetse kuti madzi a cryogenic akusunthidwa bwino komanso moyenera, tikupangira kuti muyike bwino vacuum insulation, kugwirizana ndi zinthu, komanso kukhazikika kwa vacuum kwa nthawi yayitali pamwamba pa mndandanda. Kusankha koyenera kumakhudza mwachindunji kuchepetsa kutaya kutentha, kupangitsa kuti ntchitoyo ikhale yotetezeka, komanso kuchepetsa mtengo wa chinthucho pa moyo wake wonse.
NdiPaipi Yosinthasintha Yotetezedwa ndi Vacuum, mutha kusuntha pakati pa zida zokhazikika ndi zosuntha popanda kuwononga netiweki ya mapaipi a cryogenic. Mayankho osinthasintha amatha kuthana ndi kugwedezeka, kupindika kwa kutentha, ndi kulolerana kwa kukhazikitsa popanda kusokoneza magwiridwe antchito, mosiyana ndi olimbaChitoliro Chotetezedwa ndi Zitsulo.
Ku HL Cryogenics, timaonetsetsa kuti makina athu opangira mapayipi a cryogenic agwira ntchito bwino ndi zinthu zina, mongaVacuum Insulated Valve, Cholekanitsa Gawo Lotetezedwa ndi VacuumndiTanki Yaing'onoIzi zimatsimikizira kuti dongosolo lonse likugwira ntchito bwino, osati gawo limodzi lokha.
Vuto lalikulu la uinjiniya pa makina aliwonse osinthira cryogenic ndikuletsa kutentha kulowa. Pali njira zitatu zomwe kutentha kungasunthire: conduction, convection, ndi radiation.Paipi Yosinthasintha Yotetezedwa ndi Vacuumimachotsa convection kwathunthu mwa kusunga vacuum wosanjikiza wambiri pakati pa mapaipi amkati ndi akunja.
Timagwiritsa ntchito multi-layer insulation (MLI) kuti tichepetse kutentha kwa radiation, ndipo timagwiritsa ntchito zothandizira zomwe zimakhala ndi kutentha kochepa kuti tichepetse kutentha kwambiri. Makina oteteza mpweya m'malo otayira mpweya amatha kuchepetsa kutentha ndi kupitirira 90% poyerekeza ndi mapaipi wamba oteteza mpweya m'malo otayira mpweya. Izi zimachepetsa kwambiri liwiro lomwe makina a nayitrogeni wamadzimadzi kapena zomangamanga za LNG zimawira.
Pakugwiritsa ntchito gasi m'mafakitale, izi zikutanthauza kuti ndalama zochepa zimagwiritsidwa ntchito komanso njira zokhazikika.
M'ndandanda wazopezekamo
1. Kukhazikika kwa Vacuum ndi Ntchito ya Dongosolo Lopopera Vacuum Losinthasintha
2. Kusankha Zinthu ndi Kapangidwe ka Makina

●Kukhazikika kwa Vacuum ndi Ntchito ya Dongosolo Lopopera Vacuum Losinthasintha
Kukhazikika kwa vacuum kwa nthawi yayitali ndi chimodzi mwazinthu zofunika kwambiri kuganizira posankha payipi yoyatsira mpweya. Kutulutsa mpweya pang'ono kapena kutulutsa mpweya kungayambitse kuwonongeka kwa makina ambiri pakapita nthawi, zomwe zimapangitsa kuti kutentha kulowe kwambiri ndikupangitsa kuti asagwire bwino ntchito.
ZathuDongosolo la Pampu Yopumira Yopanda Mphamvuku HL Cryogenics imasamalira izi. Dongosololi ndi losiyana ndi mapangidwe a vacuum osasinthasintha chifukwa nthawi zonse limayang'ana ndikusunga mulingo wa vacuum. Izi zimaonetsetsa kuti chotenthetsera vacuum chimagwira ntchito mofanana kwa zaka zambiri.
Izi ndizofunikira kwambiri pamapulojekiti akuluakulu monga malo osungira magetsi a LNG ku Southeast Asia kapena mapulojekiti a haidrojeni ku Middle East, komwe kumakhala kovuta kukonza ndipo nthawi yopuma imakhala yokwera mtengo.
●Kusankha Zinthu ndi Kapangidwe ka Makina
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.
Kusankha zipangizo zoyenera ndikofunikira kwambiri pa miyezo ya uinjiniya wa cryogenic. Chitoliro chamkati cha aPaipi Yosinthasintha Yotetezedwa ndi Vacuumnthawi zambiri imapangidwa ndi chitsulo chosapanga dzimbiri (monga SS304 kapena SS316L) kotero imatha kupirira kutentha kochepa kwambiri popanda kusweka.
Jekete lakunja liyenera kusunga nyumbayo kukhala yolimba komanso kusunga vacuum yolimba. Zigawo zosinthika zimapangidwa ndi chitsulo chosapanga dzimbiri kuti zikhoze kupindika popanda kuzikakamiza kwambiri.
Mavoti a kuthamanga kwa mpweya ayeneranso kufanana ndi zomwe makina amafunikira. Mwachitsanzo:
Machitidwe osamutsira LNG: nthawi zambiri pakati pa mapaundi 150 ndi 300 a kupanikizika
Makina a nayitrogeni wamadzimadzi amafunika mphamvu zochepa koma kuyenda bwino.
Timaonetsetsa kuti mapangidwe athu onse akukwaniritsa miyezo yapadziko lonse lapansi monga ASME B31.3, EN 13480, ndi miyezo yoyenera ya ISO. Izi zimapatsa makontrakitala a EPC ndi magulu ogula zinthu mtendere wamumtima.
●Chitetezo Chogwira Ntchito Choyendetsedwa ndi Valve ndi Valve Box
Kuyenda ndi kuthamanga kwa madzi a cryogenic mkati mwa dongosolo la mapaipi a HL Cryogenic vacuum jacketed kumayendetsedwa pogwiritsa ntchito ma valve a HL Cryogenic opangidwa mwapadera. Zigawozi zimapangidwa kuti zizigwira ntchito moyenera kutentha kochepa kwambiri komanso kutentha kwachangu.
Pofuna kupititsa patsogolo chitetezo ndi kupezeka kwa makina, valavu iliyonse ya HL Cryogenic imayikidwa mkati mwa bokosi la valavu ya HL Cryogenic yotetezedwa. Bokosi la valavu limateteza valavu ku chinyezi, limachepetsa kudzaza kwa chisanu, ndipo limalola akatswiri kuchita kafukufuku ndi kusintha popanda kusokoneza kutentha kwa madera ozungulira.
Kapangidwe kakang'ono kameneka, kofanana ndi ka modular, kakugwirizananso bwino ndi zoletsa za malo zomwe zimapezeka m'mafakitale opangira ma semiconductor ndi malo oyeretsera.
Pa nthawi yokhazikitsa malo olumikizira magetsi a LNG ku Southeast Asia, tinapereka makina osiyanasiyana olumikizirana magetsi.Chitoliro Chotetezedwa ndi ZitsulondiPaipi Yosinthasintha Yotetezedwa ndi Vacuummu payipi ya makilomita 12. Poyamba kasitomala wathu adakumana ndi mpweya wambiri chifukwa cha njira zodzitetezera zachilengedwe.
Pogwiritsa ntchito vacuum insulation yathu pamodzi ndiDongosolo la Pampu Yopumira Yopanda Mphamvu, tinatha kuchepetsa kutuluka kwa kutentha ndi pafupifupi 85 peresenti. Izi zinatheka chifukwa chaVacuum Insulated ValvendiCholekanitsa Gawo Lotetezedwa ndi Vacuum, zomwe zinaletsa kutsekeka kwa nthunzi.
Unali kafukufuku wopambana pomwe kusankha payipi yoyenera ya cryogenic kunali kofunika kwambiri.
●Kuphatikizana ndi Ma Valves ndi Zida Zowongolera Gawo
Paipi yoyatsira mpweya sigwira ntchito yokha; kugwira ntchito kwake kumadalira kwambiri kugwirizana kwake ndi zida zina zonse.
Ma Vavu Otetezedwa ndi VacuumKuchotsa mwayi uliwonse woti kutentha kulowe ndi kupsa ndi nthunzi. Kumbali inayi,Cholekanitsa Gawo Lotetezedwa ndi Vacuumkumatsimikizira kulekanitsa bwino gawo musanapereke mankhwala osungunuka ku zida zogwiritsidwa ntchito kumapeto.
Izi ndizofunikira kwambiri pochita ndi makina a cryogenic m'mafakitale a semiconductor ku East Asia, chifukwa kusasinthasintha pang'ono kwa gawo kumatha kuwononga ntchito zovuta m'fakitale.
Mapayipi ayenera kuonedwa ngati gawo la njira yolumikizirana yolumikizirana ya cryogenic kuti zigwire bwino ntchito.
Magawo osiyanasiyana ali ndi zofunikira zosiyanasiyana za mapaipi a cryogenic.
Gawo la LNG, makamaka ku South East Asia, likufuna kuti pakhale kutetezedwa kwabwino chifukwa cha mtunda wautali komanso kutentha kwambiri. M'mafakitale opanga gasi ku Europe, miyezo yachitetezo imakhala nkhani yofunika kuganiziridwa.
Kumbali ina, m'mapulojekiti a haidrojeni ku Middle East, nkhani za kulola mpweya kulowa ndi kugwirizana kwa zinthu zimabweretsa vuto lina. Chifukwa chake, ku HL Cryogenics, timaganizira za ukadaulo wa zisindikizo ndi zinthu kuti tiwonetsetse kuti palibe kutuluka kwa madzi konse.
Ku HL Cryogenics, timagwiritsa ntchito njira yokhazikika pa dongosolo pomwe timaphatikizaChitoliro Choteteza Vacuum (VIP), mapaipi, ma valve, komanso mayankho ang'onoang'ono a thanki.
●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.
