Ke hōʻike ʻia e nā ʻenekinia hale hana hoolei waiwai waiwai hiki i nā pahu wai hydraulic koʻikoʻi a i ʻole nā hale paʻa lole kiʻekiʻe, ʻaʻole lākou e ʻimi wale ana i kahi hale kūkulu - ke ʻimi nei lākou i ke kūpaʻa dimensional ma lalo o 200 MPa kaomi, microstructure consistency ma waena o AMS 5387 cobalt alloy batches, a me ka hoʻomanawanui ʻole no ka porosity i nā nozzles-based T800. ʻO ia ka hana maoli a mākou e ʻike ai i kēlā me kēia lā ma QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ʻO ia ke kumu no nā ʻāpana i hāʻule wale ke hāʻule ka ʻōnaehana.
No ke aha i lawa ʻole ai ka hoʻolei kālā—a he aha ia
He nui nā mea hoʻolako e hoʻopaʻa inoa i ka "hoʻoili kālā" ma kā lākou pūnaewele. He kakaikahi ka mea e hoomalu ana i ke kaulahao piha: ka pono o ka wax ma ± 0.05 mm, ua hoopiliia na profiles puhi ahi i ka ± 3°C, ka manawa ninini i kokuaia i ka vacuum i loko o 0.8 kekona o ka pahu hopu, a me ka malama ana i ka wela ma hope o ka hooleleia i ± 5°C ma na 4-hola paa. Ua ʻike mākou i ʻekolu mau ʻatikala mua i hāʻule ʻole mai nā hale hana kaulana ʻē aʻe - ua ʻike ʻia nā mea āpau i ka hoʻomaloʻo ʻole ʻana o ka pūpū. Ma kā mākou hale Qingdao, hoʻomaka kēlā me kēia pūʻulu me ka ASTM E1951-compliant surface roughness verification on master patterns, a ukali ʻia e ka X-ray CT scanning of shell thick distribution before dewaxing. Pēlā mākou e paʻa ai i ka mānoanoa o ka pā i ka ≤±0.3 mm ma nā hale pahu pahu piston 120-mm-diameter—ʻoiai ke hāʻule ka pā i ka 4.2 mm.
Kahi e koi aku ai ka Cobalt Alloys ma mua o ka pale wela
ʻAʻole paʻakikī i ka mīkini ʻo Cobalt-nickel superalloys e like me AMS 5387 a me T800 - paʻakikī lākou e * wānana *. ʻO kā lākou hana paʻakikī e piʻi i ka 300% ma hope o 0.15 mm o ka hohonu o ka ʻoki. Hāʻule nā hiʻohiʻona ola mea hana maʻamau. ʻO kā mākou hoʻonā? E hoʻolei i ke ʻano geometry kokoke i ka ʻupena me ka ʻae mīkini mīkini 0.8–1.2 mm, a laila e hoʻohana i nā mea hoʻokomo CBN maʻamau me nā kihi rake 12° a me nā ʻaoʻao honed 0.03 mm—hōʻoia ʻia ma SEM i kēlā me kēia hoʻololi mea hana. No nā pahu hoʻoheheʻe kobalt i hoʻohana ʻia i loko o nā paila hoʻoheheʻe subsea, ʻoki kēia i ka manawa pōʻai e 41% ma mua o ka carbide maʻamau ʻoiai e hoʻonui ana i ke ola mea hana mai 8 a 27 mau ʻāpana i kēlā me kēia lihi. ʻO ka mea koʻikoʻi, mālama mākou i ka traceability piha: lawe kēlā me kēia ʻāpana i nā hōʻike hōʻike wili, nā palapala hōʻoia spectrographic, a me ka hōʻoia ʻana i ka nui o ka palaoa no ASTM E112. ʻAʻohe moku moku me ka ʻole o ka palapala hōʻoia o ka maʻiʻo δ-phase ≤0.5%—he mea hiki ʻole ke kūʻai ʻia no ke kūpaʻa luhi i ka hoʻouka ʻana.
Hoʻohui Kūʻokoʻa e hāʻawi maoli i ke kūpaʻa
ʻO kekahi mau mea hana i waho i ka hoʻopau ʻana. ʻO nā mea ʻē aʻe i waho i ka mālama wela. ʻAʻole mākou e hana no nā mea koʻikoʻi. ʻO kā mākou ISO 9001-hōʻoia ʻia nā hale kikowaena CNC machining me 5-axis simultaneous contouring, vacuum furnaces me ± 2 ° C like ʻole ma waena o 1.2 m³ ukana, a me nā pahu electropolishing calibrated iā Ra ≤0.1 μm ma nā kumu pahū kila kila. No ke aha la keia? No ka mea, ʻo ka hoʻoheheʻe ʻana i ka wela i ka wā e hoʻomaha ai i ke koʻikoʻi e pili pono ana i nā kāhea GD&T i nā kino valve kaomi. I ka wā i hoʻouna mai ai kahi mea kūʻai mai iā mākou i kahi kiʻi e hōʻike ana i ke kūpaʻa kūlana o Ø0.05 mm ma nā awa 10-mm-diameter ʻehā, ua holo mākou i ka hoʻohālike wela ma mua o ka hoʻolei ʻana - a laila hoʻoponopono i ka hoʻokomo ʻana i ka riser a me nā helu hoʻoluʻu e kaupalena i ke koʻikoʻi i koe. <120 MPa. Ua hala ka ʻatikala mua i ka nānā ʻana CMM ma Ø0.042 mm. Loaʻa kēlā pae mana i ka wā e hana ai ka hoʻolei ʻana, ka mīkini, a me ka mālama wela ma lalo o hoʻokahi ʻōnaehana maikaʻi-me hoʻokahi keʻena metrology like.
ʻO nā mea e pono ai nā ʻenekinia honua—a loaʻa
Ke koi nei nā OEM ʻAmelika ʻAmelika i ka palapala PPAP Level 3. Pono nā ʻoihana hydraulics ʻEulopa i ka palapala hōʻoia EN 15085-2 no nā hui welded. Ke koi nei ka poʻe ʻaelike ikehu Hikina Hema i ka hoʻāʻo paʻakai i ISO 9227 (NSS) no 1,000 mau hola. Hālāwai mākou i nā mea ʻekolu-ʻaʻole ma ke ʻano he mea hoʻohui, akā ma ke ʻano he māka i kūkulu ʻia. Loaʻa i kēlā me kēia kauoha hale hana hoʻoheheʻe waiwai hoʻoheheʻe ʻia: ka hōʻoia ʻana o nā mea maka e kūʻē i nā palapala hoʻolako hōʻoia; nā mākaʻikaʻi CMM i ka hana ma 30%, 60%, a me 90% o ka hana; ʻO ka hoʻāʻo hana hope loa (e laʻa, 1.5x helu kaomi paʻa no 30 mau minuke ma nā valve āpau); a me ka ʻike kikohoʻe piha a hiki i ka helu umu ahi a me ka ID mea hoʻohana. Hōʻike nā mea kūʻai iā mākou e hoʻopau kēia i nā lā 7-11 o ka loiloi ʻenekinia i hope a i waho. Ua ʻoki kekahi mea hana pauma Kelemania i kāna kaʻina hoʻomaka huahana hou mai 22 a 13 mau pule ma hope o ka hoʻololi ʻana i kā mākou kaʻina hana-no ka mea, ke kiʻi ʻana i ka hōʻoia, GD&T wehewehe, a me nā manaʻo hana hana i hana ʻia i hoʻokahi manawa 90 mau minuke, ʻaʻole ʻeono mau leka uila.
Inā koi kāu noi hale hana hoolei waiwai waiwai pololei—ʻaʻole i ka hoʻolei wale ʻana, akā hiki ke wānana, hiki ke hoʻopaʻa ʻia, hiki ke hana hou ʻia ka pololei—QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. Hāʻawi iā ia i kahi mea nui loa: i ke ola luhi o ka ʻāpana, kūpaʻa sila, a me ke kūpaʻa lōʻihi. ʻAʻole mākou hana i nā ʻāpana. Hana mākou i ka hilinaʻi i ka neʻe.
