Ke kuhikuhi nei nā ʻenekinia i nā ʻāpana hoʻoheheʻe hao no nā manifold hydraulic, nā hale pahū, a me nā ʻōnaehana winch, ʻaʻole lākou e kauoha wale i ka metala - ke koho nei lākou i ke kūpaʻa dimensional ma lalo o ke kaomi 350-bar, microstructural consistency ma waena o 500-unit batches, a me ka hoʻomanawanui ʻole no ka porosity i nā flanges lawe ukana. ʻO ia ke kumu e loaʻa ai mai kahi ʻoiaʻiʻo hale hana ʻāpana hao-ʻaʻole he mea hoʻokumu nui -ʻaʻole hiki ke kūkākūkā. Ua ʻike mākou i ʻekolu prototypes i hāʻule ʻole mai hoʻokahi mea hoʻolako no ka mea ʻaʻole hiki i kā lākou kaʻina hoʻolei one ke hoʻopaʻa i ± 0.15 mm ma kahi pahu cylinder 280-mm. Ua ʻoki kekahi mea kūʻai aku i ka 17% o ka hoʻouna ʻana ma hope o ka hoʻāʻo ʻana o ka ultrasonic i hōʻike ʻia i ka emi ʻana o lalo o ka ʻāina kokoke i nā wahi hoʻololi wela. ʻAʻole kēia nā hihia maʻamau. ʻO lākou ke kumukūʻai o ke koho ʻana i ka leo ma mua o ka hoʻopaʻi metallurgical.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. e hoʻonā i kēia ma ka hana ʻana i kēlā me kēia hoʻolei hao ma ke ʻano he hui hana—ʻaʻole he pākaʻi waiwai. Hoʻokumu ʻia ma Qingdao, ʻo kāna hale hoʻokō ISO e holo like ana i ka hoʻopukapuka kālā a me nā laina hoʻolei one i hoʻohālikelike ʻia no ka ASTM A48 Class 35, ASTM A, a me nā hao ductile pearlitic maʻamau. ʻAʻole like me nā hale kūʻai e hoʻoponopono i ka kemika wale nō i ka hoʻomaka ʻana o ka hoʻoheheʻe ʻana, hoʻāʻo kā lākou mea hana umu ahi i kēlā me kēia 250 kg o ka ladle ninini, e hōʻoia ana i ka carbon equivalent (CE) i loko o ± 0.03 mau helu a me ka hoʻokaʻawale silika ≤0.12%. No ke aha ia mea? No ka mea, ua hoʻopili pololei ʻia ʻo CE ma mua o ± 0.05 i ka microcracking i hoʻokomo ʻia i ka mīkini i loko o nā hale pahu pahu piston pump-a ua ana mākou iā ia ma nā holo kaʻawale ʻeono.
Hoʻopau ko lākou hoʻohui ʻana i ka helu hemahema maʻamau: nā lima lima ma waena o ka hoʻolei ʻana a me ka mīkini. ʻO ka hapa nui o nā mea hoʻolako i waho i ka hana CNC, nalowale ka mana ma luna o ka manawa hoʻomaha pilikia a me ka mōʻaukala wela. ʻO QINGDAO QIANGSENYUAN nā mīkini e hoʻolei ana i loko o 48 mau hola o ka haʻalulu, me ka hoʻohana ʻana i nā blank annealed i mālama ʻia ma 620 ° C no 4 mau hola ma mua o ka wili ʻana. ʻAʻole kēia manaʻo—ʻo ia ke ʻano o kā lākou paʻa ʻana i ka pōʻai o 0.012 mm ma nā kino valve kaomi 120-mm-diameter, ʻoiai me ka mānoanoa o ka paia e ʻokoʻa ana mai 18 mm a 42 mm. ʻO kā lākou mau wili axis nui e mālama i nā undercuts, helical grooves, a me nā counterbores i kahi hoʻonohonoho hoʻokahi - koʻikoʻi ke koi ʻia kāu kumu pahū ʻewalu mau lua M24 i hoʻopaʻa ʻia i ke kūlana GD&T o 0.05 mm e pili ana i kahi mokulele datum i hoʻokumu ʻia ma ka ʻaoʻao as-cast.
ʻAʻole pepa ka ʻike ʻana i nā mea waiwai - ʻo ia ka laser-etched batch ID ma kēlā me kēia ʻāpana, i hoʻopili ʻia i nā palapala palapala maka, nā hōʻike loiloi spectral, a me nā pihi hoʻāʻo tensile i mālama ʻia no 10 mau makahiki. I ka wā i koi aku ai kekahi OEM ʻEulopa i ka hōʻoia ʻana ua hālāwai nā nozzles kobalt-alloy i ka AMS 5387 mau ʻano paʻakikī ma hope o ka nitriding, ua huki ʻo QINGDAO QIANGSENYUAN i ka lāʻau lapaʻau wela pololei mai Malaki 2023, e hōʻike ana i ka manawa hoʻomaʻemaʻe, nā ramp rates, a me ka noho ʻana ma hope o ke anuanu—hōʻoia ʻia nā mea a pau e pili ana i kā lākou Rockwell C tester calibrated i kēlā me kēia lā. ʻAʻohe lab ʻaoʻao ʻekolu. ʻAʻohe lohi. ʻIke wale nō hiki iā ʻoe ke hoʻouna me ka ʻāpana.
Hāʻawi kēia pae o ka mana i nā hopena hiki ke wānana: 98.3% ka hua mua ma ka ʻenekini kaʻa winch center shaft rollers, 12-wiki alakaʻi manawa no nā kauoha 200-unit o T800-based iron-cobalt hybrid castings, a ʻaʻohe hemahema o ka mahina ʻai i ka aila & gas downhole valve mai 2021. ʻAʻole kā lākou ikaika. ʻAʻole lākou e hoʻolei i nā calipers brake automotive a i ʻole mea kuke. Hoʻolei lākou i ka mea e hoʻoneʻe ai i ka wai, pale i ka ʻino, a ola i ka hoʻouka haʻalulu. Inā koi kāu noi i ka hao e hana—ʻaʻole hoʻopiha wale i kahi kiʻi kiʻi—hoʻomaka me kahi hale hana e mālama i ka metallurgy e like me ke code: pololei, loiloi, a hoʻopaʻa mau ʻia.
