Ke hōʻike nei nā mea ʻenekinia i nā ʻāpana hao ductile a hina paha no nā ʻōnaehana hydraulic, nā lako ʻaila, a i ʻole nā pauma hana kaumaha, ʻaʻole pono lākou i ka hoʻolei ʻana - pono lākou. paʻa dimensional ma lalo o 300+ bar kaomi, microstructure maʻamau ma waena o 500 mau ʻāpana, a ka hoʻomanawanui ʻole no ka emi ʻana o ka porosity i nā flanges lawe ukana. ʻO ia ke kumu e loaʻa ai mai kahi ʻoiaʻiʻo hale hana hao-ʻaʻole kahi mea kūʻai kālepa a i ʻole mea hoʻokumu nui - ʻaʻole hiki ke kūkākūkā. Ua ʻike mākou i nā papahana he nui i hoʻopaneʻe ʻia e nā helu nodule graphite like ʻole, ka paʻakikī Brinell like ʻole (HBW 180–220 vs. koi ʻia 210–240), a i ʻole nā hemahema o ka ʻili i koi ʻia e hana hou ma hope o ka mīkini. ʻO ka hoa kūpono e mālama i ka metallurgy e like me ke aʻo ʻana - ʻaʻole ka manaʻo hope.
No ke aha e hoʻomaka lōʻihi ai ka pono waiwai ma mua o ka ninini ʻana
ʻO ka hapa nui o nā hemahema e hoʻihoʻi i ka hoʻokele waiwai maka-ʻaʻole ka ʻenehana hoʻolei. Ma QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., hoʻomaka kēlā me kēia pūʻulu o EN-GJS-400-15 me ka hao puaʻa i hōʻoia ʻia a me ka ferrosilicon mai ISO 9001-hōʻoia ʻia nā smelters. Hōʻoia lākou i ka carbon equivalent (CE) ma ka hōʻea ʻana me ka hoʻohana ʻana i ka loiloi hoʻoheheʻe LECO-ʻaʻole wale nā palapala hōʻoia. Ua ana mākou i ka hoʻoheheʻe ʻana o CE a hiki i ka ± 0.15% i nā ʻāpana i hōʻoia ʻole ʻia, e hoʻopiʻi pololei ana i ka nodularity i nā hale ʻāpana mānoanoa. Hoʻohana ʻia kā lākou lab i ka hōʻoia ASTM A536 i kēlā me kēia wela: ka ikaika tensile, elongation, a me ka paʻakikī - ua hoʻopaʻa ʻia me ka ID umu, ka manawa ninini, a me ka nui o ka hoʻoilo. ʻAʻohe puka "representative sample". ʻAʻole ʻoi loa kēia - ʻo ia ke ʻano o ka mālama ʻana i nā hale cylinder no nā paila piston a ± 0.02 mm ka pōʻai ma hope o ka mālama ʻana i ka wela.
Kahi e hui ai ka hoolei one i ke a'o CNC
ʻO nā ʻāpana hao hina e like me nā kumu pahū a i ʻole nā kino valve e koi i ka palahalaha (<0.05 mm ma luna o 600 mm) a me nā lua mīkini pololei. ʻAʻole hiki i ka hoʻolei ʻana i ke one wale nō ke hāʻawi. Hoʻopili ʻo QINGDAO QIANGSENYUAN i ka ʻāpana me ka mana kaʻina hana i hoʻohui ʻia: hoʻohana kā lākou mea hoʻokumu i nā lepo lepo i hoʻopaʻa ʻia i ka resin me ka nānā ʻana i ka wai i ka manawa maoli, a laila hoʻololi pololei i nā kiola i loko o ka hale 5-axis CNC cell. ʻAʻohe lima lima waho. ʻAʻohe mea kolo ma waena o ka hoʻolei ʻana a me ka mīkini hoʻopau. Mīkini lākou i nā wahi hoʻopaʻa koʻikoʻi i ka wā e hoʻomaha mau ana ka hoʻolei ʻana - e ʻoki ana i ka distortion thermal e 40% versus post-annealing machining. No nā kiwi puʻe e koi ana i ka passivation AMS 2700 Class 2, hoʻohui lākou i ka peening pana a me ka hoʻomaʻemaʻe nitric acid ma mua o ka nānā hope ʻana. ʻAʻole ia he "casting + machining." ʻO ia kahi kaʻina hana ʻenehana.
ʻO ka hōʻoia ʻana o ka honua: ʻo ka mea e hoʻāʻo maoli ai nā mea kūʻai aku
ʻAʻole ʻae nā mea kūʻai ʻaila o ʻAmelika ʻĀkau i nā hōʻike hoʻāʻo - hōʻoia lākou i ka hana. Ua hoʻāʻo kekahi mea kūʻai i 12 winch center shaft rollers ma lalo o 120,000-cycle fatigue loading ma -20°C. Ua hala nā mea a pau. Ua holo kekahi i nā nozzles cobalt-alloy (AMS 5387) e kūʻē i ka slurry abrasive no 72 mau hola—ʻeleʻele ʻole ma mua o 0.03 mm hohonu. ʻAʻole kēia he mau ʻike lab. ʻO lākou nā ʻāpana hana i hoʻouna ʻia me ka traceability piha: ka helu wela, ka paʻi ʻana i ke kemika, ka hōʻike CMM no nā kelepona GD&T āpau, a me ka micrograph e hōʻike ana i ka morphology graphite no ISO 945-1. I ka wā i koi aku ai kekahi ʻElepa pāma OEM i ka ʻikepili paʻakikī paʻakikī paʻa ISO 13003 no ka hao hina hina EN-GJL-250, ua hāʻawi lākou i nā waiwai hopena Charpy V-notch—ʻaʻole wale nā kikoʻī tensile. Pēlā ʻoe e pale aku ai i nā mea kupanaha "ua maikaʻi ia i ke kiʻi".
Ke koho ʻana i kāu hale hana hao hao: ʻekolu mau hōʻoia hiki ʻole ke kūʻai aku
- E noi i kā lākou mau moʻolelo pūʻulu hope ʻekolu—aole palapala. E hōʻoia inā hoʻopaʻa ʻia ka paʻakikī, ka ikaika tensile, a me ka hoʻohui kemika i kēlā me kēia wela, ʻaʻole i ka hailona.
- Pono e hōʻoia i ka hoʻohana ʻana i ka CMM-ʻaʻole wale ka nānā hope. Pono e nānā ʻia nā ana koʻikoʻi ma hope o ka hana ʻana a ma mua o ka ʻoki ʻana.
- E hōʻoia iā lākou nona nā waiwai hoʻolei a me ka mīkini. Hoʻohui nā kaʻina hana i waho i 7-12 mau lā alakaʻi a hoʻokomo i nā hewa alignment ʻaʻole hiki ke hoʻoponopono i ka leka GD&T.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. halawai me na mea ekolu. Hoʻohana ʻia kā lākou hale hana ma Qingdao ma lalo o ISO 9001:2015 a mālama i nā kaʻina hana i kākau ʻia no kēlā me kēia hana—mai ka hoʻomākaukau ʻana i ke one a hiki i ka ʻeke hope. Hoʻouna lākou i ʻAmelika ʻĀkau, ʻEulopa, a me Asia Hikina Hema me nā palapala kuʻuna piha a me ka hoʻokō RoHS/REACH i kūkulu ʻia i loko o nā kikoʻī waiwai. Inā pono e ola kou hale hao ductile hou i 20 mau makahiki i loko o ka mea hoʻokele valve subsea—a i ʻole e hoʻomāluulu kou kumu pahū hao hina i ka haʻalulu ma 3,600 RPM—e hoʻomaka me ka ikaika metallurgical, ʻaʻole nā koi kūʻai. ʻO ka ikaika loa hale hana hao ʻaʻole hoʻohiki i ka hemolele. Hōʻike ia i ke kūlike—hoʻokahi wela, hoʻokahi hoʻolei ʻana, hoʻokahi ana i ka manawa.
