Ke kuhikuhi nei nā mea ʻenekinia i nā ʻāpana mechanical ductile hao no nā ʻōnaehana hydraulic, nā kīwaha ʻaila, a i ʻole nā hui winch hana koʻikoʻi, ʻaʻole lākou e koho wale i kahi mea - ke koho nei lākou i ke kūpaʻa dimensional ma lalo o 300+ bar pressure, ka pale ʻana i ka luhi ma hope o 10⁶ ka hoʻouka ʻana, a me ka hoʻomanawanui ʻole no ka micro-shrinkage ma nā wahi hoʻopaʻa koʻikoʻi. ʻO ia ke kumu i kumu ʻole ai nā OEM alakaʻi ma ʻAmelika ʻAmelika a me ʻEulopa i nā hoa hana hale hana ductile hao ma ka catalog — nānā lākou i nā kaʻina hana hoʻoheheʻe, hōʻoia i ka kūlike o ka nodularity ma waena o nā wela, a hōʻoia i nā kiʻi koʻikoʻi koʻikoʻi ma mua o ke kau inoa ʻana i nā PO.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. Hoʻohana ʻo ia i hoʻokahi o ia ʻano hana-ISO-certified, one-and-investment casting-hiki, me nā cell CNC calibrated i ± 2 µm repeatability ma nā hiʻohiʻona ma lalo o 0.5 mm mānoanoa pā. Ua hana mākou ma luna o 17,000 mau hale hao ductile no nā mea hana piston pump mai 2019. Ma kēlā me kēia pūʻulu, ana mākou i ka helu nodular (ASTM A247), ka ikaika tensile (ka liʻiliʻi 415 MPa), a me ka elongation (≥10%) - ʻaʻole hoʻokahi wale nō ma ka pā, akā ma ʻekolu mau kūlana axial no ka hoʻolei ʻana. No ke aha mai? No ka mea, hiki i kahi wahi ma lalo o ka nodular i loko o ka flange hale cylinder ke hoʻomaka i ka hoʻolaha ʻana o ka luhi ma ka 180 rpm hana mau. Ua ʻike mākou i ka hana ʻana. A ua hoʻolālā hou mākou i nā ʻōnaehana gating e hoʻopau iā ia.
Hoʻokaʻawale ʻo Vertical integration i nā mea hoʻolako hilinaʻi mai nā mea kūʻai kālepa. Ma QINGDAO QIANGSENYUAN, ʻaʻole haʻalele nā mea hoʻolei hao ductile i ka hale a hiki i ka nānā hope ʻana. Loaʻa nā mea maka i hōʻoia mua ʻia: FCD450 a i ʻole FCD600 ka hao, hiki ke ʻike ʻia i ka helu wela o ka umu a me ka loiloi ladle. Hana ʻia ka hoʻoheheʻe ʻana i loko o nā bay hoʻoheheʻe ʻia i ke aniau; kālua ʻia nā cores i nā kikoʻī maʻamau (≤0.8%); Hoʻopaʻa ʻia ka manawa shakeout i kēlā me kēia pōʻai hoʻolei. A laila hele mai ka mīkini-ʻaʻole ma ke ʻano he ʻanuʻu kaʻawale, akā ma ke ʻano he hoʻonui wela o ke kaʻina hana. Hoʻopaʻa paʻa mākou i nā kelepona GD&T ma ka concentricity (± 0.015 mm) a me ka hoʻopau ʻana o ka ʻili (Ra ≤1.6 µm) ma nā maka hoʻopaʻa ʻana no ka mea ʻo ka misalignment ma waena o ka noho valve a me ke kino hao ductile e pili pono i ka leakage ma ka hoʻāʻo API 598. Hoʻouna mai nā mea kūʻai mai iā mākou i nā kiʻi me ka hoʻomanawanui kūlana ʻoi aku ka paʻakikī ma mua o kā lākou hui ponoʻī—a hui pū mākou me lākou.
Hiki i kekahi ke hoʻopaʻapaʻa ʻo ka hoʻolei ʻana i waho e lawe i ka pilikia o ke kaulahao lako. Akā ʻaʻole i wehewehe ʻia ka hilinaʻi e ka palapala honua - ua hōʻoia ʻia i ka kūlike metala. I ka hoʻololi ʻana o ka OEM pauma ʻEulopa i kā mākou hale hana ʻāpana ʻāpana hao ductile no AMS 5387 cobalt-alloy pump rotors *a me ka hoʻohālikelike ʻana i nā hale hao ductile, pono lākou i nā coefficient hoʻonui wela ma waena o nā mea ʻelua. Hoʻokumu pū mākou i kahi protocol inoculation maʻamau me kā mākou mea hoʻolako maka—e hoʻohui i ka ferrosilicon rare-earth-modified i nā wela hoʻoheheʻe pololei—e hoʻololi i ka graphite nodule morphology me ka ʻole o ka hoʻohaumia ʻana i ka ikaika tensile. Ka hopena? Pākuʻi helu i loko o 0.3×10⁻⁶/°C ma waena o 20–200°C. ʻAʻohe hana hou. ʻAʻohe hemahema o ke kahua. Hana hou wale.
Hāʻawi mākou i nā ʻāpana hao ductile pololei inā ʻaʻole hiki ke koho ʻia: ʻo nā kīwī kaomi e holo ana i 12 manawa i kēlā me kēia minuke no 15 mau makahiki, winch center shaft rollers e kākoʻo ana i nā ukana ikaika 8-ton i nā wahi paʻakai paʻakai, nā kumu paʻa e hoʻopaʻa ana i nā kaʻa 300 kW ma nā kahua o waho. Hāʻawi kēlā me kēia ʻāpana i ka hiki ke ʻike piha ʻia—helu wela, ka loiloi kemika, nā hopena hōʻike paʻakikī, nā loulou hōʻike CMM. Loaʻa i kēlā me kēia hoʻouna ka hōʻoia dimensional e kūʻē i nā koi o ka mea kūʻai aku-ʻatikala mua-ʻaʻole nā ʻae ISO maʻamau. Inā koi kāu noi hale hana ʻāpana mīkini hao ductile hiki ke mālama i ka ASTM A536 Grade 65-45-12 ma ke ʻano he hoʻomaka—ʻaʻole he kaupaku—pono ʻoe i ka mana nodularity i hōʻoia ʻia, ka ʻike kaʻina hana hoʻoheheʻe ʻia, a me ka palapala QA hoʻopaʻapaʻa ʻole. ʻAʻole kēlā ʻōlelo kūʻai. ʻO ia ka pepa kikoʻī a mākou e hāʻawi ai i nā mea kūʻai aku ma mua o ka haʻi ʻana.
