Ke kuhikuhi nei nā ʻenekinia i nā lawelawe ʻoihana hoʻoheheʻe kila, ʻaʻole lākou e kauoha wale i nā ʻāpana - ke hoʻopaʻa nei lākou i ke kūpaʻa dimensional ma lalo o nā ukana hydraulic 300-bar, microstructure integrity ma hope o ka mālama ʻana i ka wela, a me ka hoʻopau ʻana i ka ʻili e hoʻohua ʻole i ka cavitation i nā hale pahū kiʻekiʻe. Ma QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., ua hoʻolei mākou ma luna o 12,000 mau mea kila a me nā mea kila kila no nā kiwi puʻupuʻu, nā hale pahu pahu piston pump, a me nā wili pahu winch center - paʻa kēlā me kēia i ± 0.05 mm GD&T tolerances ma nā hiʻohiʻona datum koʻikoʻi. ʻAʻole hiki mai kēlā pae o ka hana hou ʻana mai nā mea hana wale nō. Mai ka hoomalu ana i ke kaulahao piha: AMS 5387 cobalt alloy feedstock, one casting molds valided with thermal simulation, CNC machining that reference as-cast datums-aole theoretical models—a CMM inspection before and after stress-relief annealing.
No ke aha ke koi ʻana o ka hoʻolei ʻana i ke kila kila i ka hoʻohui pū ʻana—ʻaʻole he mea hana wale
Manaʻo ka hapa nui o nā mea kūʻai aku "ka hoʻolei pololei ʻana" ʻo ia hoʻi ka paʻa ʻana i ka hoʻomanawanui. ʻOi aku ka paʻakikī o ka ʻoiaʻiʻo. Hiki ke paʻa i ± 0.3 mm ke kahua hoʻoheheʻe kila 316 i hoʻolei ʻia i ke one—akā, ʻo kona ʻauwaʻa e kau ana e pono ke pā i ka ± 0.03 mm ka holo ʻana *ma hope o ka mālama ʻana i ka wela a me ka mīkini hope. ʻO ia kahi e hāʻule ai nā kaulahao hāʻawi ʻāpana. Hoʻokahi mea kūʻai aku. Nā mīkini ʻē aʻe. Hana ke kolu i ka NDT. Hiki i kēlā me kēia lima ke kuhi hewa ʻole, ka hoʻololi ʻana i ka datum, a i ʻole nā microcracks i hōʻike ʻole ʻia.
Holo mākou i nā laina hoʻopukapuka a me nā laina hoʻolei one * i loko o ka hale ISO 9001 like * kahi e hana ai kā mākou pūnaewele CNC 5-axis. Ke hoʻouna ka mea kūʻai i kiʻi kiʻi no ka T800 cobalt alloy nozzle, nānā kā mākou mea ʻenekini kaʻina hana * ma mua o ka haʻi ʻana: Ua lawa anei ka mānoanoa o ka pā e pale i ka haehae wela i ka wā paʻa? Hiki i ke kiko kikoʻī ke hoʻokuʻu maʻemaʻe me ka ʻole o ka wili ʻana ma hope o ka hoʻolei ʻana i mea e hoʻopilikia ai i ka ʻili o ka corrosion? Hiki ke hoʻopaʻa ʻia ka ʻāpana i ka mīkini i nā papa hana āpau i hoʻokahi hoʻonohonoho - e hoʻopau i ka hewa kumulative?
ʻAʻole kēia he manaʻo. I ka makahiki i hala aku nei, ua hoʻouna mai kahi ʻEulopa hydraulics OEM iā mākou i kahi hoʻolālā kino valve i hoʻoponopono ʻia me kahi iwi ʻaoʻao 2.5-mm-mānoanoa. Ua hōʻailona kā mākou hui hoʻokumu ʻana iā ia ma ke ʻano he hiki ke emi i ka porosity. Ua noi mākou i kahi paʻi koʻikoʻi kūloko a hoʻoponopono i ka ʻōnaehana gating. Ka hopena: ʻaʻohe ʻōpala ma waena o 420 mau ʻāpana, kūʻē i ka 27% hōʻole i kā lākou mea hoʻolako mua.
ʻO ke kumu kūʻai maoli o "E hoʻolei wale iā ia"—A no ke aha ʻaʻole koho ʻia ka hiki ʻana o nā mea waiwai
ʻO kekahi mau huaʻōlelo o ka hale hana hoʻoheheʻe kila me ka manaʻo ikaika-a ʻike ʻoe i nā palapala palapala. Pono mākou i nā hōʻike hoʻāʻo wili (MTRs) no kēlā me kēia wela, i hoʻopaʻa ʻia me nā helu pūʻulu ma kā mākou ERP. I ka wā i kuhikuhi ai ka mea kūʻai aku iā AMS 5387 no kahi plug wela kiʻekiʻe, ua ʻimi mākou i ka ingot maka i ka umu hoʻoheheʻe arc ma Kelemānia-ʻaʻole wale i ka pepa a ka mea hoʻolaha. No ke aha mai? No ka mea, ola a make paha nā alloys cobalt-nickel ma ka puʻunaue carbide. ʻO ka hoʻololi ʻana he 5°C i loko o ka hopena annealing e hoʻololi i ka paʻakikī e 8 HRB. Me ka ʻole o ka ʻike kemika a me ka mōʻaukala wela, ke pāʻani nei ʻoe i ke ola luhi.
Hōʻole pū mākou i nā ʻaoʻao pōkole "maʻamau". Inā ʻike kou hale pahū i ka hoʻouka ʻana ma luna o 150 MPa, ʻaʻole e ʻoki ʻia e 304 stainless—no ka maikaʻi o ka hoʻolei ʻana. Hoʻohālikelike mākou i ka ASTM A743 CF8M a i ʻole 17-4PH i hoʻololi ʻia me ka H1150 ʻelemakule, ma muli o ke kūlana koʻikoʻi a me ka hoʻohālikelike ʻana i ka wai. ʻO ka hoʻopaʻi ʻana he 12-18% ʻoi aʻe ma mua. Akā, hoʻopau ia i nā hemahema o ke kahua e kūʻai ana i ka 30 × ʻoi aʻe i ka wā haʻahaʻa, nā ʻōlelo hōʻoia, a me ka hōʻino maikaʻi.
He aha ka mea maoli ma waena o kāu kaha kiʻi a me ka hoʻouna ʻana
ʻAʻole linear kā mākou kaʻina hana - he mea hoʻololi:
- pule 1: Hōʻoia GD&T + manaʻo hana hana. Hōʻike mākou i nā hiʻohiʻona e like me ka radii pā lahilahi ma lalo o 0.8 mm a i ʻole nā puka makapō i ʻoi aku ka hohonu ma mua o 8x anawaena—a laila e hōʻike i nā mea ʻē aʻe e mālama ai i ka hana akā e ʻoki i ka manawa pōʻai e 35%.
- wiki 2–3: Ka hana ʻana i ka mold + ka hoʻolei ʻana i ka ʻatikala mua. Hoʻouna mākou i nā kiʻi radiographic a me ka nānā ʻana kemika—ʻaʻole nā hōʻike dimensional wale nō.
- wiki 4: ʻO ka mīkini me nā loiloi CMM i ka hana i kēlā me kēia hana. ʻAʻohe "nānā hope wale nō."
- wiki 5: ʻO ka hoʻāʻo hana hope loa: nā hoʻāʻo ʻana i ka pōʻino a hiki i ka 400 bar, ka hōʻoia ʻana i ka ʻeleʻele o ka ʻili no ISO 4287, a me nā palapala traceability piha.
Hoʻouna mākou i nā prototypes i nā lā 18. ʻO nā kauoha liʻiliʻi liʻiliʻi (50-500 pcs) e hāʻawi i loko o 6-8 mau pule-me nā lā paʻa i laka ʻia ma ke kākau ʻana, ʻaʻole nā kuhi leka uila.
ʻO ka hale hana hoʻoheheʻe kila ma ke ʻano he hui ʻenehana—ʻaʻole hana wale
Inā makemake ʻoe i kahi hale hana hoʻoheheʻe kila e hana ana i kāu kaha kiʻi ma ke ʻano he ʻaelike - ʻaʻole he manaʻo - e ʻike ʻoe i ka alignment ma QINGDAO QIANGSENYUAN. ʻAʻole mākou e alualu i ka leo haʻahaʻa. Hoʻoponopono mākou i nā ʻano hana ʻole: ka ʻāʻī ʻana i nā nozzles cobalt alloy, ka ʻāʻī ʻana i loko o nā ʻōpuʻu kila stainless steel, distortion i ka hoʻolei hao ʻāpana nui ma hope o ka mīkini.
ʻO kā mākou hana aʻe e hōʻoiaʻiʻo ana iā AS9100 no nā hoʻolei kila aerospace a me ka hoʻonui ʻana i kā mākou kelepona hoʻolei-machining hybrid no nā ʻāpana superalloy kokoke i ka upena. Akā, ʻaʻole ka waiwai o kēia lā i nā hoʻolālā e hiki mai ana - aia ma ka 99.2% mua-pass yield ma AMS 5387 ʻāpana pamu, ka 0.02 mm palahalaha ma 400-mm-diameter stainless steel flanges, a me ka ʻoiaʻiʻo ua hoʻohana mākou i ka 73% o kā mākou mea kūʻai hou iā mākou no ʻelima mau makahiki.
Inā ʻaʻole hiki ke kūʻai ʻia ka pololei o ka dimensional, ka pono waiwai, a me ka ʻoiaʻiʻo o ka lawe ʻana - e hoʻomaka me ka hale hana hoʻoheheʻe kila kila e ana i ka kūleʻa i nā microns, ʻaʻole nā palena.
