Ke kuhikuhi nei nā mea ʻenekinia i nā ʻāpana kila kila no nā valve hydraulic, nā hale pahū, a i ʻole nā winch shaft - nā ʻāpana e pono e ola i ka 300+ bar pressure, abrasive slurry flow, a i ʻole cyclic thermal stress - ʻaʻole lākou e nīnau "He aha ke ʻano o ka hoʻolei ʻana?" Nīnau lākou: "E paʻa anei kēia ʻāpana i ka hoʻomanawanui ± 0.02 mm *a me ka pale ʻana i ka corrosion i loko o ka lawelawe wai kai *a me ka moku i 6 pule?" Ma laila kahi ʻoiaʻiʻo hale hana kila kuhiliʻole nalowale loaʻa kona wahi-ʻaʻole ma ke ʻano he mea kūʻai aku, akā ma ke ʻano he hoʻonui hoʻolālā.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ke hoʻohana nei i kekahi o ia ʻano hana ma Qingdao. Ua hoʻolei mākou i nā kino valve AISI 316L no nā modules control subsea subsea kahi kahi kīnā microporosity e hoʻomaka ai ka hōʻole piha. Ua hana mākou i ka mīkini AMS 5387 cobalt alloy nozzles no nā paila wahie hoʻoheheʻe kiʻekiʻe—ʻoi aku ka paʻakikī o nā mea hana carbide ma mua o ka mea i manaʻo ʻia—a hāʻawi i nā ʻāpana ʻatikala mua me ka ʻokoʻa mānoanoa o ka pā i hōʻoia ʻia e CMM ma lalo o 0.015 mm. ʻAʻole kēia he mana theoretical. Hiki ke hana hou ʻia ma waena o 127 hana i ka makahiki i hala wale nō.
ʻEkolu mau mea ʻenehana i hoʻokaʻawale i ka hoʻoheheʻe ʻana i ka wax mai nā hale kūʻai maʻamau "hoʻoheheʻe kālā" - a no ke aha lākou i mea nui ai i kāu kaʻina manawa papahana a me ka hilinaʻi o ka māla:
- Hoʻomaka ka traceability ma mua o ka hana ʻana: Hoʻokumu mākou i nā ingots stainless steel i hōʻoia ʻia i ka ASTM A743/A744 Grade CF8M a me EN 1.4408—me nā palapala hōʻoia wela piha, nā hōʻike loiloi spectrographic, a me nā hopena hoʻokolohua intergranular corrosion i waiho ʻia i kēlā me kēia ʻāpana. ʻAʻohe pānaʻi pani. ʻAʻohe mea hoʻololi i ka "papa like" me ka ʻole o ka hōʻailona ʻenehana.
- Noho ka mana ana ma ke kumu, ʻaʻole ka hōʻike nānā: ʻO kā mākou mau hiʻohiʻona wax he CNC-machined mai POM paʻa, ʻaʻole resin paʻi 3D. No ke aha mai? No ka mea, paʻa ka POM i ka ± 0.01 mm ma luna o 200 mm ma 22°C ambient—a emi i ka wānana i ka wā dewaxing. ʻAʻole i manaʻo ʻia nā kumu i paʻi ʻia ma luna o 150 mm. Hōʻoia mākou i kēlā me kēia ʻano me ka nānā ʻana i ka contour optical *ma mua o ka hoʻomaka ʻana o ke kūkulu ʻana.
- ʻAʻole hiki ke hoʻopaʻa ʻia ka pono o ka ʻili no ka sila hana: ʻAʻole hoʻomaʻamaʻa ʻia kahi noho valve kaomi no ka nānā ʻana. Hoʻopili ʻia i ka Ra ≤0.4 µm *ma hope o ka mālama ʻana i ka wela—no ka mea, ʻo ke koʻikoʻi koʻikoʻi i loko o ka ʻili i hoʻolei ʻia ke kumu o ka micro-cracking ma lalo o ka ukana cyclic. Hoʻohui mākou i ka annealing solution (1050°C + water quench) a me ka wili hoʻomaha hoʻomaha i hoʻokahi kaʻina mana. ʻAʻole ʻelua mau hana kaʻawale.
Hiki i kekahi ke hoʻopaʻapaʻa e loaʻa i ke kumu kūʻai like no nā ʻāpana kulika nui. Akā inā makemake kāu hale pahu pahu piston pump i nā ala hoʻoluʻu o loko me 3.2 mm ka mānoanoa o ka paia, concentricity ma lalo o 0.05 mm ma waena o 320 mm ka lōʻihi, a ʻaʻohe lua o loko - ʻaʻole hiki ke hoʻolei ʻia ke one. Hāʻawi ka wax nalowale. Ua ana mākou i ka loaʻa ʻole o ka lua ma ka 94.7% no nā hale ma lalo o 12 kg, me ka 61% no nā mana hoʻohālikelike one-cast i kā mākou hōʻailona kūloko. ʻO ka ʻokoʻa? Ka hoʻomalu ʻia ʻana o ka shell mold permeability, precise preheat ramp rate, and vacuum-kōkua i ka ninini ʻia—ua hoʻopalike ʻia nā mea a pau no kēlā me kēia papa alloy a me ka mānoanoa ʻāpana.
He aha ke ʻano o kēia no kāu hoʻoholo kūʻai? ʻO ka mea mua, ka hoʻopili manawa alakaʻi. Hoʻohui kā mākou lean workflow i ka loiloi GD&T * i ka wā o ka hoʻonohonoho ʻana i ke ʻano wax - ʻaʻole ma hope o ke kūkulu ʻia ʻana o nā mea hana. Hoʻopaʻa mākou i nā pilikia kiʻi kikoʻī, nā kaha poho, a i ʻole ka hoʻopilikia ʻana i kāu faila STEP i loko o 48 mau hola. ʻO ka lua, hoʻemi pilikia. Loaʻa kēlā me kēia hoʻoheheʻe kila kuhili ʻole i ka 100% MPI (ka nānā ʻana i nā ʻāpana magnetik) * a me ka hoʻāʻo ultrasonic no nā hemahema o lalo. ʻO ke kolu, scalability. Ke holo nei mākou i nā laina hoʻopaʻa paʻa paʻa-hoʻokahi no nā prototypes wikiwiki (7-10 mau lā), ʻo kekahi no nā kauoha medium-volume (50-500 pcs) me nā pōʻai kapuahi paʻa a me nā pūʻulu mālama wela ma hope o ka hoʻolei ʻana. ʻAʻole pono ka hoʻoponopono hou ʻana ma waena o nā hailona.
E nānā i mua: ʻO ka palena aʻe ʻaʻole ʻoi aku ka paʻa o ka hoʻomanawanui - ʻo ia ka hana hybrid. Hoʻokomo pololei mākou i nā hiʻohiʻona ʻimi mīkini i loko o ke ʻano hoʻoheheʻe kālā. Ua hiki mai ke kahua pahū me kona mau puka kau, nā wili pine dowel, a me nā wahi hoʻopaʻa paʻa i hoʻopau ʻia e CNC—e hoʻemi ana i nā hana lua e 68%. No ka T800 cobalt-based superalloys, hoʻohui mākou i ka paʻa kuhikuhi i ka wā o ka hoʻolei ʻana me ka cryogenic machining e mālama i ka pono o ka hale palaoa. ʻAʻole kēia mau manaʻo R&D. Ke holo nei lākou i ka hana ʻana no ʻekolu ʻEulopa OEM i kēia lā.
Inā makemake ʻoe i nā ʻāpana kila kila kahi i koho ʻole ʻia ka hāʻule - a ma kahi o ka "pololei" ʻo ia ka mea hiki ke ana, hiki ke hana hou ʻia, ka hana i kākau ʻia - a laila e hui pū me kahi hale hana kila kuhiliʻole nalowale ʻO ka mālama ʻana i ka metallurgy e like me ka physics, ʻaʻole folklore, hoʻololi i nā mea āpau. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ʻaʻole hoʻolei wale i ka metala. Hōʻoia i ka hana.
