Ke haki ka hale o ka pauma hydraulic ma 450°C, a i ole ia, a i ole ia, e pau ana ka nozzle kobalt alloy ma lalo o ka cyclic thermal shock, oki ka "hale hana pale wela ki'eki'e" i hua'ōlelo hulina—e lilo ia i manawa pau. Ua ʻike mākou iā ia ma nā ʻaelike lawelawe ʻaila ʻAmelika ʻAmelika, i ka hoʻihoʻi hou ʻana o ka valve waho waho o ʻEulopa, a ma waena o nā mea kanu desalination ʻo ʻAsia Hema. ʻO ka mea e paʻa ai, ʻaʻole ia he pale wela wale nō - ʻo ia ke kūlike metala, ke kūpaʻa dimensional ma hope o ka hoʻokele wela, a me ka ʻae ʻole no ka hoʻokaʻawale microstructural. ʻO ia ke kumu i kuhikuhi ai nā ʻenekinia - ʻaʻole wale nā mea waiwai - akā ʻo ka kiʻekiʻe-mehana kū'ē 'āpana hale hana mahope o lakou.
Hoʻomaka ka hana honua maoli ma mua o ka hana ʻana. Ma QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., e hoʻomaka ana kēlā me kēia AMS 5387 cobalt alloy me ka hōʻoia ʻana i ka ʻike maka—i lalo i ka helu wela a me ka hōʻike hōʻike wili. ʻAʻole mākou e ʻae i nā palapala hōʻoia "kūpono"; hōʻoia mākou i ka hāʻawi ʻana i ka nui o ka palaoa ma nā bila e hiki mai ana me ka hoʻohana ʻana i nā protocols ASTM E112. No ke aha mai? No ka mea hiki i ka 5% deviation i ka carbide dispersion ke ʻoki i ke ola lawelawe e 60% i nā hui pahū lole kiʻekiʻe. I loko o kahi papahana hou no ka OEM kaʻa ʻenekinia Kelemania, ua loaʻa i kā mākou loiloi spectral i loko o ka hale i ka neʻe ʻana o ka maʻiʻo nickel marginal i loko o kahi pūʻulu alloy T800-ma mua o ka hoʻolei ʻana. Ua pale ʻia kēlā ʻike ʻana i ka 120 i hāʻule ʻole i nā wili kumu waena ma nā ʻōnaehana winch e hana ana ma 520°C ka wela o ka ʻili a me 120 MPa hoʻouka manawaleʻa.
ʻAʻole he huaʻōlelo ʻo ka hoʻohui ʻana i ke kūpaʻa ma ʻaneʻi-ʻo ia ke ʻano o kā mākou hoʻomalu ʻana i ka mea nui loa: ka hana hoʻololi ʻana i ka wā hoʻomaha. ʻO nā hale hao hoʻoheheʻe one no nā pamu piston e hoʻokele ʻia i loko o kā mākou mau kapuahi hoʻomaʻamaʻa wela-ʻaʻole i waho. ʻO ia ke ʻano o ka helu nodule graphite hiki ke wānana (ASTM A247 Class 3), ka paʻakikī like ʻole (220–260 HBW), a ʻaʻohe koena i hoʻoulu ʻia i ke kaumaha ma hope o ka pau ʻana o CNC. I kēia manawa, loaʻa iā HIP'd (hoʻopiʻi isostatic wela) nā nozzles hoʻolele hoʻolimalima i ka hoʻolei ʻana no ka hoʻopau ʻana i ka microporosity - koʻikoʻi ke hāʻule ka mānoanoa o ka pā ma lalo o 2.3 mm a ʻoi aku ke kaomi hana ma mua o 350 bar. Nīnau nā mea kūʻai: "Hiki iā ʻoe ke hoʻopaʻa i ka ± 0.015 mm ma kahi hale cylinder 320 mm anawaena ma hope o 3 mau hola ma 480°C?" ʻAe—no ka mea, ke hōʻoia nei mākou i nā koena ulu wela ma nā geometries laʻana ma mua o ka hana piha ʻana, ʻaʻole ma hope.
Manaʻo kekahi poʻe e hiki mai ana ka mana kiʻekiʻe mai nā alloy exotic wale nō. Akā ʻike mākou i nā hemahema mai ka hoʻokō GD&T maikaʻi ʻole ma mua o ke kemika hewa. Hiki ke hoʻohana ʻia ke kila kīwila F22 maʻamau i ke kino kīpē paʻi—akā inā ʻaʻohe mana kūpono o kona wahi hoʻopaʻa noho e pili ana i ka ʻau, piʻi ka leakage ma 300°C. ʻO ia ke kumu ʻaʻole i alakaʻi ʻia kā mākou nānā ʻana. Loaʻa i kēlā me kēia mea koʻikoʻi ka hōʻoia CMM e kūʻē i ke kumu hoʻohālike CAD mua-ʻaʻole wale i nā ana inoa wale nō-a me ka profileometry optical ma nā maka sila e hōʻoia i ka Ra ≤ 0.4 µm ma hope o ka passivation. No nā ʻāpana T800 maʻamau ʻole, holo mākou i ka hōʻoia ʻana o ka pōʻai wela: ʻekolu mau pōʻaiapuni piha mai ka ambient a 550°C, a laila hoʻāʻo hana ma ka helu kiʻekiʻe. ʻAʻohe ʻokoʻa. ʻAʻohe waivers.
Inā ʻoe e ʻimi nei i nā hoa hana hale hana i kēia lā, e nānā ma waho o nā palapala hōʻoia ma ka paia. Nīnau: No lākou kā lākou mālama wela? Hiki iā lākou ke hōʻike iā ʻoe i nā kiʻi microstructure mai ka nui o AMS 5387 o ka mahina i hala? E nānā pū anei lākou i kāu GD&T callouts ma mua o ka haʻi ʻana—a me ka hae kahi e hoʻonui ai ka hoʻomanawanui ʻoi aku ka uku akā ʻaʻohe hana? QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. hana kēia ʻano no ka mea ʻaʻole hāʻawi ʻia ka hilinaʻi i loko o kahi pahu hoʻouna. Hoʻokumu ʻia i kēlā me kēia helu wela, kēlā me kēia ala hana, kēlā me kēia moʻolelo nānā. ʻO ka manawa aʻe e wela ai kāu ʻōnaehana, ʻaʻole pono e ola kāu mau ʻāpana - pono lākou e hana. Hoʻomaka kēlā me ke koho ʻana i ka mea nāna e mālama i nā ʻano mea nui.
