Ke hāʻule ka pauma hydraulic i loko o kahi ʻaila aila waho—a i ʻole nahā ka pahu kaomi i ka wā o ka hoʻāʻo ʻana i ka pōʻaiapuni kiʻekiʻe—e hoʻi pinepine ke kumu kumu i hoʻokahi hoʻoholo: koho mea. ʻAʻole ʻo ia wale nō ka hōʻailona hoʻolako ʻana i nā ʻāpana mechanical alloy-Cobalt. He hōʻoia hana ia no nā ʻōnaehana kahi e hoʻopau ai ka haʻalulu wela, ka ʻaʻahu abrasive, a me nā ukana 20,000-psi mau i ka palena no ka hewa.
No ke aha e koi ai nā ʻāpana kobalt i ka hana kūikawā-ʻaʻole ka mīkini maʻamau
ʻAʻole "ʻoi aku ka paʻakikī o ka mīkini." He mea ʻino lākou: ʻoi aku ka wikiwiki o ka hana ma mua o ka ʻoki ʻana i ka mea paahana, hoʻokaʻawale i ka wela i mea e paʻa ai ka wela ma ke kikowaena, a me ka microstructurally sensitive i ke koena o ke koʻikoʻi a i ʻole ka ʻoluʻolu ʻole. Ua ʻike mākou i nā hale kūʻai e hoʻāʻo ana i nā nozzles T800 ma nā wili CNC maʻamau - e ʻoki wale i 60% o ka ʻatikala mua e holo ana mai ka micro-cracking i ka wā o ka mālama wela. Pono ka holomua ma mua o nā hoʻokomo carbide. Ke koi nei ia i nā kahe hana hoʻoheheʻe ʻia, ka hoʻoheheʻe ʻana i ka lewa ma mua o ka hoʻoulu ʻana, a me nā ala hana hoʻololi i alakaʻi ʻia e CMM e hahai ana i ka deflection i ka manawa maoli i loko o nā hale pāpaʻi lahilahi.
ʻO ia ke kumu e hoʻomaka ai ka hiki ʻana o nā ʻāpana mīkini paʻa kobalt maoli i ke kahawai—i ka hiki ʻana o nā mea. ʻO kēlā me kēia billet AMS 5387 a mākou e hana nei e lawe i nā hōʻike hoʻāʻo wili piha, me ka loiloi spectral i hōʻoia ʻia me ka ASTM E1099 a me ka nui o ka palaoa i hōʻoia ʻia no ASTM E112. ʻAʻohe pānaʻi pani. ʻAʻohe mea hoʻololi i ka "papa like". Inā hōʻike kāu kaha kiʻi i ka AMS 5387, loaʻa iā ʻoe ka AMS 5387—ʻaʻole like me ka 0.3% emi mai ka chromium a me ka paʻakikī wela.
ʻEhā mau mea hiki ʻole ke kūkākūkā ʻia ma hope o nā ʻāpana cobalt koʻikoʻi
Pono ka hoa paʻa pono e hoʻopuka i ke kūpaʻa-ʻaʻole hoʻokahi wale nō, akā ma waena o ka holo ʻana o 500-unit a me 10 mau makahiki i manaʻo ʻia ke ola. ʻO kēia nā mana a mākou e hōʻoia ai ma mua o ka haʻi ʻana:
- ʻO ke kūpaʻa nui ma o ka hana hybrid: ʻO nā puʻupuʻu hoʻoheheʻe kobalt i hoʻolei ʻia i ke one ke emi me ka manaʻo ʻole. ʻO kā mākou hoʻonā? ʻO nā cores hoʻolei kālā me nā ʻili hoʻopaʻa i hoʻopau ʻia e CNC—e paʻa ana i ± 0.015 mm ma nā anawaena 120-mm me ka ʻole o ka distortion post-machine.
- ʻO ka pono o ka ʻili ma luna o ka pau ʻana o ka ʻili: He mea ʻole ka Ra 0.4 µm inā hoʻomaka ka luhi. Hoʻohana mākou i ka RPM haʻahaʻa, ka hoʻopau ʻana i ka hānai kiʻekiʻe me nā mea hana cryogenically mālama ʻia-a hōʻoia i ka pono o lalo ma o ke kiʻi kiʻi SEM cross-sectioned ma nā ʻatikala mua.
- Ka hōʻoia ʻana ma mua o GD&T: ʻAʻole ʻae ʻia ka nozzle kobalt alloy ma hope o ka nānā ʻana o CMM. Ke hoʻomau nei ia i ka calibration kahe ma 350 ° C, ka hoʻāʻo ʻana i ka erosion me 80-grit silica slurry ma 12 m/s, a me ka nānā ultrasonic no ka porosity kūloko no ASTM E1961 Level 3.
- Hiki ke ʻimi i ka palapala ʻāina i ka nānā ʻole ʻana: Hoʻouna ʻia kēlā me kēia ʻāpana me kahi palapala hōʻoia QR-coded e hoʻopili ana i ka helu wela o nā mea maka, nā lāʻau o ka umu ahi, nā kaha manawa nānā, a me ka ID operator. Ke kū ʻole ka mahina ʻai, ʻaʻole manaʻo nā mea ʻenekinia - hoʻokaʻawale lākou i ke kumu i nā hola, ʻaʻole nā wiki.
Ma kahi i hāʻule ʻole ai nā mea hoʻolako maʻamau—a hāʻawi ka poʻe loea
Hana kekahi mau mea hana i nā ʻāpana kobalt ma ke ʻano he "mea hao ʻē aʻe." Kuhi lākou ma muli o ke kaumaha, ʻaʻole ka moʻolelo wela. Hoʻopuka lākou i ka hoʻolei ʻana i nā ʻāpana ʻaoʻao ʻekolu me ka ʻike ʻole o ka cobalt - a laila hakakā me ka ʻano dendritic inconsistent. Hoʻokuʻu lākou i ka hoʻoheheʻe ʻana i ke kaumaha ma mua o ka hana ʻana i ka mīkini hope, e hoʻoulu ai i ka warpage i loko o nā hale pahu piston pump cylinder ma hope o ka hui ʻana.
Ua loaʻa iā mākou nā mea kūʻai aku e hoʻololi i ka waena o ka papahana ma hope o ka ʻike ʻana i kā lākou mea hoʻolako mua i hoʻohana i ka ʻōpala cobalt recycled me nā ʻaoʻao o ka trace element i hōʻoia ʻole ʻia. Ka hopena? ʻO ka ʻāʻī ʻana o ka wā mua i nā ʻōwili pahu waena winch ma lalo o ka haʻawe torsional cyclic. ʻAʻole kā mākou pane i hoʻololi wale ʻia - ʻo ia ka loiloi metala hui, hoʻoponopono hou ʻia nā manawa hoʻomaʻamaʻa wela, a hoʻolālā hou i nā ala hoʻouna ʻoluʻolu ma ka papahana CNC. ʻO ia ka hoʻohui kūpaʻa: ka hoʻolei ʻana, ka mīkini, ka mālama ʻana i ka wela, a me ka NDT ma lalo o hoʻokahi hale, me ka ʻike kaʻina hana like ʻole - ʻaʻole nā lima.
Ke koho ʻana i kāu hale hana ʻāpana mīkini hoʻohui i ka cobalt: ʻekolu nīnau e hoʻokaʻawale i nā hoa mai nā mea kūʻai aku
Ma mua o kou kau inoa ʻana i kahi NDA, e nīnau i kēia—ʻaʻole no nā pane kūʻai aku, akā no nā hōʻike i kākau ʻia:
- “E hōʻike mai iaʻu i kāu mau ʻāpana AMS 5387 hope ʻekolu—nā palapala wili, nā lāʻau mālama wela, a me nā hōʻike CMM hope loa." Hōʻike ke kūpaʻa ma ka pepa, ʻaʻole nā ʻōlelo hoʻohiki.
- "He aha kou lōʻihi i kākoʻo ʻole ʻia no nā kumu T800 ma Ø45 mm—a pehea ʻoe e hoʻomalu ai i ka pololei i ka wā e huli ai?" Hōʻike nā palena honua maoli i ke kūlana oʻo.
- "Inā makemake kā mākou hoʻolālā hale pāpaʻi i kahi pā 0.8-mm kokoke i kahi kihi kūloko 90 °, he aha kāu kihi kikoʻī liʻiliʻi - a pehea ʻoe e hōʻoia ai i ka hoʻopiha piha ʻana i kēlā wahi?" Hoʻāʻo kēia i ka ʻike hoʻolei ʻana, ʻaʻole wale ka mākaukau mīkini.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. Hoʻohana ʻo ia i kahi hale hana ma Qingdao i hōʻoia ʻia i ka ISO 9001: 2015, me nā pūnaehana hana cobalt-alloy i hoʻolaʻa ʻia, i loko o ka hale optical emission spectrometry, a me ka calibrated coordinate ana mīkini e holo ana i ka polokalamu PC-DMIS. Aia i loko o kāna kōpili nā nozzles hoʻoheheʻe ʻia ʻo cobalt no nā pahū haʻihaʻi kiʻekiʻe, ʻo nā ʻāpana pauma AMS 5387 e hālāwai ana i nā koi API 6A, a me nā ʻāpana T800 maʻamau no nā modula mana subsea. Hāʻawi ka hui i nā mea kūʻai aku ʻoihana ma waena o ʻAmelika ʻAmelika, ʻEulopa, a me ʻAsia Hikina Hema - e hāʻawi ana i nā prototypes i nā lā 12, nā kauoha medium-volume i 6-8 mau pule, me ka hiki ke hoʻopaʻa ʻia a me ka hoʻokō dimensional i kūkulu ʻia i kēlā me kēia pae.
ʻAʻole i loko o nā mīkini ʻoi aku ka mana o ka cobalt-based alloy mechanical parts — akā i ka hoʻohui ʻoi aku ma waena o ka metallurgy, machining physics, a me ka hōʻoia hana. I ka piʻi ʻana o ka ʻōnaehana a hoʻonui ʻia nā manawa lawelawe, ʻaʻole e ana ʻia ka ʻokoʻa ma waena o ka ʻae ʻia a me ka ʻoihana koʻikoʻi i nā microns. E ana ʻia i ka manawa hana, nā palena palekana, a me nā kumukūʻai āpau o ka ʻona. E koho e like me.
