He aha kaʻu e makaʻala ai i ka nānā ʻana i nā pahu mālama wai cryogenic?

Ua māhele ʻia ka nānā ʻana o ka pahu mālama wai cryogenic i ka nānā ʻana o waho, ka nānā ʻana o loko a me ka nānā ʻana i nā ʻaoʻao he nui. Pono e hoʻoholo ʻia ka nānā ʻana o nā pahu mālama cryogenic i kēlā me kēia manawa e like me nā kūlana loea o ka hoʻohana ʻana i nā pahu mālama.

 Ma ke ʻano laulā, ʻo ka nānā ʻana o waho ma ka liʻiliʻi hoʻokahi manawa i ka makahiki, ʻo ka nānā ʻana o loko ma ka liʻiliʻi hoʻokahi manawa i kēlā me kēia 3 mau makahiki, a ʻo ka nānā ʻana i nā ʻaoʻao he nui ma ka liʻiliʻi hoʻokahi manawa i kēlā me kēia 6 mau makahiki. Inā ʻoi aku ka lōʻihi o ke ola lawelawe o ka pahu mālama haʻahaʻa ma mua o 15 mau makahiki, e hana ʻia kahi nānā ʻana o loko a me waho i kēlā me kēia ʻelua makahiki. Inā he 20 mau makahiki ke ola lawelawe, e hana ʻia kahi nānā ʻana o loko a me waho ma ka liʻiliʻi hoʻokahi manawa i kēlā me kēia makahiki.

1. Nānā kūloko

 1). Inā paha he ʻaʻahu ʻino ma ka ʻili o loko a me ka pahu mālama pilina manhole, a inā paha he mau māwae i loko o ke kuʻi wili, kahi hoʻololi o ke poʻo a i ʻole nā ​​wahi ʻē aʻe kahi i kau nui ʻia ai ke kaumaha;

 2). Ke loaʻa ka pala ma nā ʻili o loko a me waho o ka pahu, pono e hana ʻia nā ana mānoanoa o ka paia he nui ma nā ʻāpana i manaʻo ʻia. Inā emi ka mānoanoa o ka paia i ana ʻia ma mua o ka mānoanoa o ka paia liʻiliʻi i hoʻolālā ʻia, pono e nānā hou ʻia ka hōʻoia ikaika, a me nā manaʻo no ka hiki ke hoʻomau ʻia ka hoʻohana ʻana a pono e waiho ʻia ke kaomi hana kiʻekiʻe i ʻae ʻia;

 3). Ke loaʻa nā hemahema o ka paia o loko o ka pahu e like me ka decarburization, ka palaho stress, ka palaho intergranular a me nā māwae luhi, pono e hoʻokō ʻia ka nānā ʻana i ka metallographic a me ke ana ʻana o ka paʻakikī o ka ʻili, a e waiho ʻia kahi hōʻike nānā.

2. Nānā waho

 1). E nānā inā paʻa ka papa anti-corrosion, ka papa insulation a me ka papa inoa lako o ka pahu mālama, a inā paha ua piha, ʻike a hilinaʻi hoʻi nā mea pono palekana a me nā mea hoʻomalu;

 2). Inā he mau māwae, deformation, overheating kūloko, a pēlā aku ma ka ʻili waho;

 3). Inā paha e liki ana ke kuʻina wili o ka paipu hoʻohui a me nā ʻāpana kaomi, inā paha e paʻa ana nā ʻūmiʻi hoʻopaʻa, inā paha e piholo ana ke kumu, e hili ana a i ʻole nā ​​kūlana ʻē aʻe.

3, Nānā piha

 1). E hana i kahi nānā ʻole i hōʻino ʻia ma ka weld nui a i ʻole ka pūpū, a ʻo ka lōʻihi o ka nānā kiko he 20% o ka lōʻihi holoʻokoʻa o ka weld;

 2). Ma hope o ka hala ʻana i nā nānā kūloko a me waho, e hana i kahi hoʻāʻo hydraulic ma 1.25 mau manawa o ke kaomi hoʻolālā o ka pahu mālama a me kahi hoʻāʻo airtight ma ke kaomi hoʻolālā o ka pahu mālama. I ke kaʻina hana nānā ma luna, ʻaʻohe leaka o ka pahu mālama a me nā wili o nā ʻāpana āpau, a ʻaʻohe deformation ʻē aʻe i ʻike ʻia o ka pahu mālama e like me ka mea i kūpono;

 Ma hope o ka pau ʻana o ka nānā ʻana o ka pahu mālama haʻahaʻa haʻahaʻa, pono e hana i kahi hōʻike e pili ana i ka nānā ʻana o ka pahu mālama, e hōʻike ana i nā pilikia a me nā kumu e hiki ke hoʻohana ʻia a i ʻole hiki ke hoʻohana ʻia akā pono e hoʻoponopono ʻia a ʻaʻole hiki ke hoʻohana ʻia. Pono e mālama ʻia ka hōʻike nānā ma ka faila no ka mālama ʻana a me ka nānā ʻana i ka wā e hiki mai ana.
