ʻAʻole hoʻouna wale nā mea hoʻolako hale hana QT400-18 i ka hoʻolele moku - hāʻawi lākou i ka hilinaʻi o ke kūkulu. I ka wā e paʻa ai kāu pahu hydraulic i ka 350 bar, i ka wā e hoʻomau ai kāu kumu winch center i ka haʻalulu torsional i kēlā me kēia lā i nā kūlana o waho o Arctic, a i ʻole ke alo o ka hale pahū i ka slurry abrasive ma 120°C, ʻaʻole he footnote ka papa hao ductile. ʻO ia ke kumu. ʻAʻole ʻo QT400-18 ka hao hina hina. He microstructure graphite spheroidal me ka liʻiliʻi o ka ikaika tensile o 400 MPa a me ka elongation o 18% - kahi koena o ka ikaika, ductility, a me ka machinability i hiki i kekahi mau foundries ke hoʻokō mau i nā ʻāpana nui mai 5 a 500 mau ʻāpana.
No ke aha i hāʻule ʻole ai ka QT400-18-ʻaʻole i loko o ke keʻena, akā ma ka papahele hale kūʻai
Ua ʻike mākou i ʻekolu mau ʻano hemahema i ka honua maoli QT400-18 noi: helu nodule inconsistent ma lalo o 120/mm², ferrite/pearlite ratio e neʻe ana ma mua o 85/15%, a me ke koena o ke koʻikoʻi-induced warpage ma hope o ka pau ʻana o CNC. ʻAʻole kēia mau pilikia theoretical. ʻIke ʻia lākou e like me nā māhā luhi mua i loko o nā hale pahu pahu piston pump, ma ke ʻano o ka ʻae ʻole ʻana i loko o nā kino valve kaomi, a i ʻole he micro-cracking i ka wā o ka pana ʻana. ʻO ke kumu kumu? ʻO ka hapa nui o nā papa inoa "QT400-18" ma ka pūnaewele e kuhikuhi wale ana i ka kemika inoa wale nō - ʻaʻole ka mana o ka hoʻolei ʻana. ʻO ka hoʻokō ʻoiaʻiʻo e koi i ka mana koʻikoʻi ma luna o ka manawa lapaʻau magnesium, ka wela inoculation, ka nui o ka hoʻoluʻu ʻana i ka mold, a me nā pōʻai hoʻomaha ma hope o ka hoʻolei ʻana. Ma kā mākou hale Qingdao, ʻo kēlā me kēia QT400-18 wela ka nānā ʻana i ka spectral analysis, nodule morphology verification ma o ASTM E2399, a me ka hoʻāʻo tensile no ISO 6892-1-ʻaʻole wale ma nā pahu hoʻāʻo, akā ma nā kākika ʻelele i ʻoki ʻia mai ka ʻāpana mānoanoa o ka hoʻolei ʻana.
Hoʻoponopono ka hoʻohui kū pololei i ka mea huna o nā lau kikoʻī
Nui nā mea kūʻai mai QT400-18 castings mai kahi mea kūʻai aku a hoʻopau iā lākou ma kekahi. Hoʻokumu kēlā handoff i nā wahi makapō. Mīkini mākou i kēlā me kēia ʻāpana QT400-18 i loko o ka hale-ma hope koke o ka hoʻomaha ʻana i ke kaumaha, ma mua o ka hoʻomaka ʻana o ka hoʻoheheʻe ʻana. ʻOki pololei ʻia kā mākou mau ʻāpana ʻelima CNC mai ka hoʻolei ʻana i ke one ʻōmaʻomaʻo me ka hoʻohana ʻana i ka mea hana carbide i hoʻopaʻa ʻia no ka hao ductile ferritic. No ke aha la keia? No ka mea, ʻo ka hana ʻana i ka QT400-18 me ka ʻole o ka helu ʻana i kāna 12-15% ka haʻihaʻi leo graphite ke kumu i kūkulu ʻia ai ke kamaʻilio ʻana, ka ʻoki ʻoki ʻana, a me ka micro-tearing subsurface. Hoʻoponopono mākou i ka nui o nā meaʻai ma 18% haʻahaʻa ma mua o nā palena hao maʻamau a hoʻohana i nā nozzles hāʻawi hoʻoluʻu i hoʻonoho ʻia i loko o 12 mm o ka ʻoki ʻoki. ʻO ka hopena: ʻo ka ʻeleʻele ʻili Ra ≤ 0.8 μm ma nā ʻaoʻao hoʻopaʻa paʻa koʻikoʻi, ʻaʻohe hana hou ma ka concentricity bore no nā kiwi wai hydraulic.
ʻAʻole ʻo Traceability ka pepa - he physics
I ka hōʻike ʻana o kahi mea kūʻai aku ma Kelemania i ka lole i manaʻo ʻole ʻia ma ke kahua pāpaʻi QT400-18, ua ʻimi mākou i ka pilikia ʻaʻole i ka hoʻolei ʻana - akā i ka hoʻoheheʻe ʻana o ka mea hoʻoheheʻe mīkini ma lalo o 7.2% i ka wā o ka hopena pule. ʻO ka hiki ke huli piha ʻo ia ka hoʻopili ʻana i kēlā me kēia ʻāpana i kāna helu wela waiwai, ka pahu manawa log umu, ka pihi hoʻomaha hoʻomaha hoʻomaha, ka hōʻike nānā CMM, a me ka pūʻulu hoʻoluʻu kikoʻī i hoʻohana ʻia i ka wā hoʻopau.

Hoʻomaka kāu papahana QT400-18 ma mua o ke kauoha
ʻAʻole mākou e ʻōlelo i nā hoʻolei. Hoʻopili pū mākou i nā hoʻonā. Ke hoʻouna aku nei ʻoe i kahi hoʻohālike CAD o kahi kino valve kiʻekiʻe, e nānā kā mākou metallurgists i nā neʻe ʻana o ka mānoanoa o ka pā no ka pilikia paʻa. ʻO kā mākou machinists hae i lalo e koi ana i nā mea hana maʻamau.
