He kūpono kēia ʻano hana e ʻike ai i nā leaks liʻiliʻi loa—a hiki i ka 5 × 10⁻¹³ mbar·L/s. ʻAʻole mākou e pau ma laila. Kākoʻo mākou i kēia me ka hoʻāʻo piʻi kaomi static, i hiki iā mākou ke ʻike pololei i ka wikiwiki o ka hōʻino ʻana o kahi vacuum i ka hala ʻana o ka manawa. Ma kēlā ala, hiki iā mākou ke ʻike i nā leaks a nānā i ka pono o ka ʻōnaehana holoʻokoʻa i hoʻokahi manawa. Eia nō naʻe, ʻo ka nānā maʻalahi loa ka mea mua: e nānā wale i ka hau ma ka ʻaʻahu waho. Pono kēlā me kēia mea hoʻohana e ʻike he hōʻailona mua paha kahi ʻāpana hau. A no nā ʻōnaehana i hoʻopaʻa ʻia, he mea pono ka ʻike ʻana i ka leak ultrasonic. E ʻohi ia i nā leaks mai kahi mamao o 50 kapuaʻi.
Ma HL Cryogenics, hoʻohana mākou i kēia mau ʻano hana āpau, e pili pono ana i nā kūlana ASME, CE, a me ISO. Inā hePaipu Hoʻokaʻawale Vacuum, heHose palupalu i hoʻopaʻa ʻia me ka Vacuum, a i ʻole kahi Mini Tank, haʻalele kēlā me kēia huahana i kā mākou hale hana e hoʻokō ana i nā koi paʻa leak, mākaukau no ka lawelawe ma nā wahi āpau o ka honua.
ʻAʻole kala ka hoʻoili wai cryogenic i nā hewa. E noʻonoʻo e pili ana iā ia: ke holo nei ʻoe i ka naikokene wai ma -196°C a i ʻole LNG ma -162°C ma o kahi paipu i ka wā e like ai ka mahana o ka ea ma waho me ka mahana o ka lumi. Nui loa ka hakahaka mahana—ʻoi aku ma mua o 250°C. Inā nui ka wehe ʻana o kahi puka pine i loko o ka papa hakahaka, komo ka ea i loko. I ka manawa koke, lilo kēlā mau molekala ea i mau alahaka wela liʻiliʻi, e wāwahi ana i ka insulation. Piʻi ka wela, hoʻolapalapa wikiwiki ka huahana, a lilo ia i mea pipiʻi—ʻoi aku hoʻi ma nā kikowaena LNG ma Asia Hikina Hema, kahi hoʻokahi spool i hāʻule ʻole hiki ke hoʻonele i nā tausani kālā o ka huahana i kēlā me kēia lā.
Akā, ʻoi aku ka hohonu o nā pilikia ma mua o ke kālā. Ua hoʻopaʻa inoa ka European Industrial Gases Association i nā hihia kahi i alakaʻi ai nā liki kūloko i loko o nā pahu i hoʻokaʻawale ʻia me ka vacuum i ka pōʻino. E noʻonoʻo i kēia: hana ʻia kahi māwae luhi i loko o kahi wili, komo ka wai cryogenic i loko o ka hakahaka vacuum, a anuanu loa ka ʻaʻahu waho a lilo i mea palupalu. Ke haki hope loa, pana mai nā ʻāpana kila me ka ikaika make. Ua like mau ke kaulahao o nā hanana a he mea weliweli mau. ʻO ka ʻike mua ʻana i kēia mau pilikia ʻaʻole ia he mea maikaʻi wale nō—he mea nui loa ia no ka palekana.

ʻAʻole pono ʻoe i nā lako hana nani no ke ʻano ʻike maʻalahi a hilinaʻi hoʻi—ʻo ka poʻe akamai wale nō i ʻike i ka mea e nānā ai. KePaipu Hoʻokaʻawale Vacuuma i ʻole ka nalowale ʻana o ka Mini Tank i kona vacuum insulating, e anu koke ka wahi a puni ka leaka. Inā lawa ke anuanu e hoʻopaʻa ai ka makū mai ka lewa, e paʻahau, a hana i nā ʻāpana hau maopopo ma ka ʻaʻahu waho. Kū i waho kēlā, ʻoi aku hoʻi ma ka ʻaoʻao o ke koena o ka paipu i ka mahana o ka lumi.
Hōʻike mau mākou i nā mea hoʻokele o kā mākou mea kūʻai aku pehea e hana ai i kēia mau nānā maka maʻamau. Hoʻoikaika lākou i nā mea kānalua maʻamau: nā wili, nā flanges, nā valves, a me nā pilina. Inā ʻike kekahi i ka hau a i ʻole ka hau ma waho o ka ʻaʻahu—me ka ʻike ʻole ʻia o ka wai—he hae ʻulaʻula koke ia. ʻO ia hoʻi, e hoʻōki, e kani i ka alarm, a hoʻomaka i kahi nānā diagnostic piha. Ua hoʻōki kēia ʻano hana pololei i nā hanana he nui ma mua o ko lākou piʻi ʻana. He mea maʻamau ia ma nā hana kinoea ʻoihana ʻEulopa a me nā hale hana semiconductor Hikina ʻAsia, kahi e hiki ʻole ai ke kūkākūkā i ka loaʻa ʻana o ka lako LN₂ mau.
Hōʻike ka hoʻāʻo piʻi ʻana o ke kaomi static iā ʻoe inā e paʻa ana ka vacuum i loko o kahi ʻōnaehana cryogenic, akā ʻaʻole ia e hōʻike pololei iā ʻoe i kahi o ka leaka. He maʻalahi ke kaʻina hana: e sila i ka vacuum annulus, e hoʻopili i kahi anakahi vacuum i hoʻoponopono ʻia, a e nānā pehea e loli ai ke kaomi i ka hala ʻana o ka manawa.
Me nā Vacuum Insulated Valves a i ʻole Phase Separators, holo pinepine mākou i kēia hoʻāʻo ma luna o 24 mau hola, e hoʻomaka ana mai ke kaomi ma lalo o 1 × 10⁻³ Pa. Inā piʻi ke kaomi ma mua o ka palena i hoʻonohonoho ʻia—ka mea a ISO 20486 a i ʻole ASTM E1603 e kau nei—ʻo ia ka hōʻike he leaka a nui paha ka puka ʻana mai kahi mea i loko. He koʻikoʻi kēia hoʻāʻo—a hiki i ka 1 × 10⁻¹² Pa·m³/s—no laila ua kūpono ia i ka paʻakikī, ʻoiai no nā papahana hydrogen ma ka Hikina Waena me kā lākou mau kūlana leaka paʻa loa.
Hana 3: Hoʻāʻo Leak Spectrometer Mass Helium
ʻO ka hoʻāʻo ʻana i ka leaka o ka spectrometer nui helium ke kūlana gula no ka ʻimi ʻana a me ke ana ʻana i nā leaka i loko o nā ʻōnaehana vacuum-insulated. Hilinaʻi mākou i ka helium no kekahi kumu maʻalahi: ʻo ia ka molekole kinoea inert liʻiliʻi loa. Hele malū ia ma waena o nā leaka liʻiliʻi i hiki ʻole i nā kinoea ʻē aʻe ke hiki aku, akā ʻaʻole ia e pane me nā lako a hōʻino paha i ka wai cryogenic.
Eia ke ʻano o ka hana maoli ʻana o ke kaʻina hana. Hoʻomaka mākou ma ka huki ʻana i kahi vacuum i loko o ka annulus, e hoʻopaʻa ana i ka spectrometer mass i hoʻopaʻa ʻia ma ka puka vacuum. A laila neʻe mākou i loko me nā pahū pōkole o ka helium, e pīpī ana ma kēlā me kēia wahi kānalua - nā wili, nā flanges, nā hui, a me nā wahi pili ma kaPaipu Hoʻokaʻawale Vacuum, Hose palupalu, a me nā ʻākoakoa Valve. Inā loaʻa kahi leaka liʻiliʻi loa, loaʻa iā ia ka helium. Paheʻe ke kinoea i loko o ka hakahaka vacuum, honi ka spectrometer iā ia, a hōʻike koke i kahi alarm.
Pono nā leaka kūloko i kahi hana ʻokoʻa. Ma kahi o ka pīpī ʻana, hoʻouka mākou i ka helium i loko o ka paipu o loko, e kaomi ana iā ia. Inā puka kekahi ma o kahi pinhole i ʻike ʻole ʻia i loko o ka vacuum annulus, ʻohi ka mea ʻike i ke kaha ma kahi. Ma ka hoʻololi ʻana ma waena o kēia ʻano "pīpī" a me ka hoʻāʻo "pressurization", ʻaʻole mākou e waiho i kekahi ala i nānā ʻole ʻia - i loko a i waho paha.
Hoʻopaʻa mau mākou i nā kūlana koʻikoʻi o ASME Standard V, Article 10, a me Appendix IV a me V. Hiki i kēia ʻano hana ke ʻike i nā leaka i lalo i 5 × 10⁻¹³ mbar·L/s—kahi pae e hiki ai i kekahi mau ʻano hana ʻē aʻe ke hoʻohālikelike.
Hana 4: ʻIke ʻana i ka leaka Ultrasonic
Lilo ka ʻike ʻana o ka ultrasonic i mea hana kūpono e hele pū me ka hoʻāʻo ʻana o ka helium i ka nānā wikiwiki ʻana o nā ʻōnaehana i kaomi ʻia e ka cryogenic. Hoʻopuka ka kinoea e pakele ana i loko o kahi ʻōnaehana i kaomi ʻia i nā hoʻokuʻu acoustic ultrasonic ma muli o ke kahe turbulent. No laila, me ka hoʻohana ʻana i kahi mea ʻike ultrasonic lawe lima, hiki i nā loea ke ʻike i nā leaka i loko o nā pipelines a hiki i nā ʻākoakoa paʻakikī e like me ka Vacuum Insulated Flexible Hose a me nā hoses cryogenic me ka ʻole o ka hoʻopilikia ʻana i nā hana ma ka ʻōnaehana.
Lilo kēia ʻano hana i mea pono loa i ka ʻike ʻana i nā leaka i nā hale hana e pono ai ka hana mau, e like me nā mea e pili ana me nā hale hana LNG a i ʻole nā hale hana kinoea ʻoihana. A hiki i 50 kapuaʻi ka mamao mai kahi o ka leaka hiki i nā loea ke ʻike i kahi o ka leaka i loko o ke kahua hana, e lilo ia i hoʻāʻo wikiwiki, akā ʻaʻole i maʻalahi ma mua o ka spectrometry mass helium.
Eia nō naʻe, ʻaʻole ka hopena o ka moʻolelo ka ʻike ʻana i nā leaka - ʻo ka pale ʻana i nā leaka kekahi pahuhopu o ka ʻenekinia. HL CryogenicsPaipu Hoʻokaʻawale Vacuuma me nā hoʻolālā Mini Tanks e komo pū me nā hana palekana he nui e pili ana i ka pale ʻana i ka hōʻino ʻana o ka vacuum.
ʻO ke ʻano nui o nā ʻōnaehana vacuum a HL Cryogenics ʻo ia kaʻŌnaehana Pamu Vacuum Dynamic, ka mea e hōʻoiaʻiʻo ana i ka mālama pono ʻana o ka vacuum i nā manawa āpau o ka hana ʻana o nā lako. ʻAʻole like me nā ʻōnaehana vacuum kuʻuna e ʻeha nei i ka hōʻino mālie ʻana o ka vacuum ma muli o ka hoʻopuka ʻana o nā mea kūloko, hoʻopau mau kā mākou ʻōnaehana i nā kinoea koena mai ka annulus, e mālama ana i ka pono o ka insulation vacuum ma lalo o 1 × 10⁻³ Pa. Hoʻonui ka mālama dynamic i ke ola o nā lako.
He mea nui nō hoʻi ke koho pono ʻana i nā mea hana. Hoʻohana wale mākou i nā kila kila austenitic (304L a me 316L), e hōʻoiaʻiʻo ana i ka paʻakikī a me ke kūpaʻa i ka palaho ma nā mahana cryogenic o -269°C. Hana ʻia kā mākou mau wili āpau e like me nā koi ASME Section IX a nānā ʻia kēlā me kēia ma o ka hoʻokolokolo radiographic a i ʻole dye-penetrant ma mua o ka hoʻāʻo ʻana i ka vacuum. Ua hōʻoia ʻia kā mākou huahana e ASME, CE a me ISO, e hāʻawi ana i ka hiki ke hana i nā huahana e like me ke kūlana o kekahi ʻāina - inā he kūlike PED no nā mākeke ʻEulopa, ASME B31.3 no nā kikowaena LNG ʻAmelika, a i ʻole GB/T 18442 no nā kinoea ʻoihana Kina.
Hoʻoholo
E lawe i kahi papahana hou ma kahi kikowaena hoʻoheheʻe LNG ma Asia Hikina Hema. Aia ma mua o 200 mika oPaipu Hoʻokaʻawale Vacuum, kekahi mau ʻākoakoa Valve Insulated Vacuum, a me kekahi mauHose palupalu i hoʻopaʻa ʻia me ka Vacuumpono e hoʻokomo ʻia nā pilina no ka hoʻoili ʻana mai ka moku a i uka. ʻO ka hana mua o kā mākou ʻano hana ʻike leak, ʻo ia ka hoʻāʻo ʻana i ka helium mass spectrometer o nā wili a me nā hui āpau i loko o kā mākou hale hana, ma mua o ka lawe ʻia ʻana o nā lako i ke kahua.
ʻO ka lua o ka hana, ʻo ia ka hoʻāʻo hou ʻana ma kahi e hoʻohana ana i ka hoʻāʻo spectrometer mass helium a me ka hoʻāʻo ultrasonic. I ke kaʻina o ka mea hope, ua loaʻa i nā loea kahi hōʻailona acoustic ʻokoʻa mai kahi pilina flange, kahi i nānā mua ʻia. Ua hōʻike ka hoʻāʻo Helium i kahi leakage ma lalo o 1 × 10⁻⁸ mbar·L/s, kahi e hoʻohaʻahaʻa ai i ka hana insulation vacuum i nā mahina hana ma hope. Ma hope o kā mākou hoʻoponopono ʻana i ka sila flange a me nā hoʻāʻo hou ʻana, ua hōʻoia pono ʻia ka paʻa o ka leakage. I kēia manawa, hana mau ke kikowaena no ʻekolu mau makahiki, me ka ʻole o ka hōʻino ʻana o ka vacuum.
No laila, ʻo ka ʻike ʻana i ka leaka i loko o nā paipu insulated vacuum ʻaʻole ia he ʻenehana hoʻokahi, akā he kaʻina hana ʻenekinia paʻakikī e hoʻohui ana i ka nānā ʻana i ka maka, ka hoʻāʻo piʻi kaomi, ka hoʻāʻo spectrometer nuipa helium a me ka nānā ʻana ultrasonic.
Hoʻokomo ʻia kēia mau ʻano hoʻāʻo āpau i ke kaʻina hana QA ma HL Cryogenics, a no laila kēlā me kēiaPaipu Hoʻokaʻawale Vacuum, Hose palupalu i hoʻopaʻa ʻia me ka Vacuum, Kiwikā Hoʻokaʻawale Vacuum,Hoʻokaʻawale ʻia ka Vacuum Insulated PhaseʻO r, a me Mini Tank i hāʻawi ʻia e mākou e kū nei i nā kūlana kiʻekiʻe loa o ka honua.
