Nā Nīnau i Nīnau Pinepine ʻia (FAQ) - Cryogenic Globe Valve (-196°C)
Q: He aha ka ʻokoʻa ma waena o kahi kiwikā poepoe cryogenic a me kahi kiwikā poepoe maʻamau?
A: Loaʻa i nā kiwikā poepoe cryogenic kekahi mau hiʻohiʻona koʻikoʻi i loaʻa ʻole i nā kiwikā maʻamau: ka pāpale i hoʻolōʻihi ʻia me ka pā drip e pale i nā sila kumu; ka mālama cryogenic hohonu o nā ʻāpana āpau; nā mea noho kūikawā (PCTFE, PEEK) no nā mahana haʻahaʻa; ka hoʻopili ʻana i ka hoʻokuʻu mahuka haʻahaʻa; a me ka hoʻāʻo hana cryogenic mandatory e like me BS 6364.
Q: He aha ka mahana lawelawe haʻahaʻa loa no kāu mau kiwikā poepoe cryogenic?
A: Ua helu ʻia kā mākou mau kiwikā poepoe cryogenic maʻamau no ka lawelawe -196°C e like me BS 6364. No ka lawelawe hydrogen wai (-253°C) a i ʻole ka lawelawe helium wai (-269°C), hāʻawi mākou i nā hoʻolālā kūikawā.
Q: He aha ka lapaʻau cryogenic hohonu a no ke aha e pono ai?
A: ʻO ka mālama ʻana i ka cryogenic hohonu ke kaʻina hana o ka hoʻomaʻalili ʻana i nā ʻāpana valve i -196°C no ka liʻiliʻi he 8 mau hola. Hoʻololi kēia i ka austenite i mālama ʻia, hoʻomaha i nā koʻikoʻi koena, a hōʻoia i ke kūpaʻa dimensional ma ka mahana lawelawe.
Q: He aha nā mea noho āu e ʻōlelo ai no ka lawelawe -196°C?
A: No ka lawelawe -196°C, paipai mākou iā PCTFE ma ke ʻano he mea noho mua. Mālama ʻo PCTFE i kona mau waiwai mechanical a hāʻawi i ka sila maikaʻi loa i nā mahana cryogenic.
Q: He mea koi ʻia ka hoʻāʻo hana cryogenic?
A: E like me BS 6364 a me ISO 28921-1, he mea koi ka hoʻāʻo ʻana i ka hana cryogenic no nā valves i hoʻohana ʻia i ka LNG a me ka lawelawe cryogenic. Hana ʻo Womic i ka hoʻāʻo hana cryogenic 100%.
Q: Ke hāʻawi nei ʻoe i ka sila bellows no nā noi leaka ʻole?
A: ʻAe. No nā noi koʻikoʻi e koi ana i ka liki ʻole o ke kumu (e like me nā wai weliweli a pipiʻi paha), hāʻawi mākou i ka hoʻolālā sila bellows me ka noho hope lua.
Q: He aha ka manawa alakaʻi maʻamau no nā kiwikā poepoe cryogenic?
A: ʻO ka manawa alakaʻi maʻamau he 8-12 mau pule no nā hoʻonohonoho maʻamau. No nā nui nui (> 12") a i ʻole nā mea kūikawā, ʻo ka manawa alakaʻi he 12-16 mau pule.
