Ke hōʻike ʻia e nā ʻenekinia 304 kila kila no nā valve hydraulic, nā hale pahū, a i ʻole nā ʻāpana winch waho, ʻaʻole lākou e koho wale i kahi mea - ke hana nei lākou i ka hoʻokō i ka pale ʻana i ka corrosion, ke kūpaʻa dimensional, a me ka hilinaʻi lōʻihi ma lalo o ke kaomi. Akā ʻaʻole lawa ka ʻimi ʻana i kēlā mea. ʻO ka mea nui ke ʻano o ka hoʻololi ʻia ʻana: ka pono o ka hoʻolei ʻana, ka pololei CNC, ka hoʻomaʻamaʻa ʻana i ka wela, ka hiki ke ʻike ʻia o kēlā me kēia melt batch. Ma laila kahi ʻoiaʻiʻo 304 hale hana kila kila hoʻokaʻawale iā ia iho - ʻaʻole ma ka helu helu, akā ma ke kaʻina hana.
No ke aha i ʻoi aku ai ka "Factory" ma mua o nā laina hana
A 304 hale hana kila kila Pono e hoʻomalu i ke kaulahao piha: nā billet maka i hōʻoia ʻia me nā hōʻike hoʻāʻo mill (ASTM A240, EN 10088-2), ka hoʻoheheʻe ʻana o ka lewa no nā koena sulfur haʻahaʻa a me ka oxygen, a me ka hoʻokaʻawale paʻa ʻana i ka wā o ka mīkini e pale ai i ka hoʻohaumia ʻana me ke kalapona a i ʻole ke kila kila. Ua ʻike mākou i nā ʻāpana he nui i hāʻule i ka lawelawe - ʻaʻole mai ka kemika alloy maikaʻi ʻole, akā mai ka passivation inconsistent ma hope o ka milling multi-axis, a i ʻole micro-cracking ma nā radii kūloko ʻoi aku ma muli o nā ala mea hana ikaika.
Ma QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., ke mālama nei mākou i ka 304 stainless ʻaʻole he waiwai, akā he ʻōnaehana hana. Loaʻa kēlā me kēia ʻāpana i ka hōʻoia spark spectrometry ma ka loaʻa. Ke hoʻohana nei ka mīkini i nā wili ʻano Swiss-like kiʻekiʻe a me nā wili 5-axis me ka hāʻawi ʻana i ka mea hoʻomaʻamaʻa-ma o ka mea hana-koʻikoʻi no ka hoʻokuʻu ʻana i nā puʻupuʻu i loko o nā lua hohonu e like me nā hale pahu piston pump cylinder. ʻAʻohe pōkole. ʻAʻohe "maikaʻi" hoʻopau ʻili. Inā makemake kāu kiʻi kiʻi iā Ra 0.4 µm ma kahi maka sila, ana mākou iā ia—ʻaʻole manaʻo ʻia—me nā profilometer tactile i hoʻopaʻa ʻia i nā kūlana NIST.
Kahi e hui ai ka Standard 304 i ka ʻenekinia Mission-Critical
Hana ʻo 304 maʻamau no nā pahu meaʻai. ʻAʻole ia e hana maʻalahi no nā hui ʻo AMS 5387 cobalt-alloy pump e hana ana ma 450°C a me 350 bar. Eia nō naʻe he nui nā mea kūʻai aku e noi mai iā mākou e mīkini i nā ʻāpana 304 * ma ka ʻaoʻao * T800 superalloys ma nā lako like. ʻO ia ke kumu e hoʻokō ai kā mākou hale hana i ka zoning koʻikoʻi: nā keena CNC stainless i hoʻolaʻa ʻia, nā wahi wili ʻē aʻe, a me nā pahu mea hana kala. Ua aʻo mākou i kēia ma ke ala paʻakikī - i ka wā o ka loiloi 2022, hoʻokahi i hoʻokomo ʻia i kahi carbide i waiho ʻia i ke koena hao ma kahi noho valve 304. Ua hala ka ʻāpana i nā loiloi dimensional—akā, ʻaʻole i hoʻāʻo ʻia ka paʻakai paʻakai ma 96 mau hola. Hoʻokomo ʻia ka haʻawina: hoʻomaka ka maʻemaʻe metallurgical ma mua o ka ʻoki mua ʻana.
ʻO kā mākou mau noi 304 pinepine e hōʻike i nā wahi koʻikoʻi o ka honua maoli: nā kino valve kaomi e koi ana i ka concentricity paʻa (<0.015 mm) ma waena o nā awa komo a me waho; nā kumu pahū e pono ai ka palahalaha ma loko o 0.05 mm ma luna o 600 mm; a me nā wili pahu waena winch i hoʻokau ʻia i nā haʻawe torsional cyclic. ʻAʻole kēia mau mea waiwai. ʻO GD&T-kaumaha lākou, me nā kūlana kūlana i kuhikuhi ʻia i nā hiʻohiʻona datum i mīkini ʻia i hoʻokahi hoʻonohonoho-ʻaʻole ʻekolu. E koi ana i ka hoʻolālā hoʻoheheʻe ʻana-machining i hoʻohui ʻia, ʻaʻole i nā handoffs sequential.
He aha ka "Hana Hana Kūʻai Pono" e hāʻawi maoli ai
"Hōʻoiaʻiʻo" ʻo ia hoʻi, hiki mai kāu prototype i nā lā 18—ʻaʻole "i loko o 3-4 pule." 'O ia ho'i, loa'a iā 'oe nā hō'ike CMM e hō'ike ana i ka 'oia'i'o vs. nominal no nā ana ko'iko'i a pau—'a'ole he pe'a ma ka papa inoa. ʻO ia ke ʻano o ka hae ʻana o kāu ʻenekinia i ka hoʻopili ʻana i ke kaha kiʻi hui, holo mākou i kahi simulation kūpono kikohoʻe *ma mua o ka ʻoki ʻana i ka metala—a manaʻo mākou i kahi hoʻoponopono radius 0.03 mm e mālama ai i $12,000 i ka hana hou ʻana.
ʻAʻole mākou e hoʻolei i waho, mālama wela, a i ʻole ka nānā hope ʻana. ʻO kā mākou mea hoʻokō ISO e mālama i ka hoʻolei kālā no nā hale 304 pā lahilahi, ka hoʻolei ʻana i ke one no nā kumu nui a hiki i ka 800 kg, a me ka hoʻoheheʻe ʻana i ka hopena ma hope o ka hoʻoheheʻe ʻana i nā umu i hoʻonohonoho ʻia me ± 3 ° C like. Loaʻa i kēlā me kēia hoʻolei ʻana ka nānā ʻana iā RT a i ʻole UT no ASTM E94/E165. Loaʻa i kēlā me kēia ʻāpana mīkini ka hōʻoia ʻike, ka nui, a me ka hoʻohana ʻana—me ka hoʻāʻo ʻana i ke kaomi ʻana i ka 1.5x kaomi hana no nā kino valve.
Hoʻoponopono kēia hoʻohui kūpaʻa i ka ʻeha nui loa a mākou e lohe ai mai nā hui kūʻai: kuhikuhi manamana lima ma waena o ka hale kūʻai, hale kūʻai mīkini, a me ka coater ke hāʻule kahi ʻāpana. Me hoʻokahi hoa kuleana, ʻo ka loiloi kumu kumu he mau hola-ʻaʻole mau mahina.
Ke koho ʻana ma waho o ka Pepa Papa
E nīnau i kekahi mea kūʻai aku: ʻo ka ʻokoʻa ma waena o ʻelua mau hale hana kila kila 304 e waiho pinepine ʻia i kā lākou mau moʻolelo hemahema - ʻaʻole kā lākou palapala. Ma QINGDAO QIANGSENYUAN, kā mākou kikowaena nonconformance database tracks kela a me keia deviation: 72% pili i ka operator-induced clamping distortion on thin flanges; 18% mai ka lawa ʻole o ka wela ma mua o ka hoʻoponopono ʻana i ka hoʻoheheʻe ʻana i nā mea hoʻolei; ʻO 10% e pili ana i ka wehewehe hewa ʻana i nā kāhea GD&T ma nā kiʻi hoʻoilina. Kaʻana like mākou i kēia mau ʻike—ʻaʻole ma ke ʻano he kūʻai aku, akā ma ke ʻano he ʻenekinia.
Inā loaʻa i kāu kauoha aʻe he 304 mau ʻāpana kila kila no nā ʻōnaehana hydraulic, nā ʻaila a me nā ʻea kinoea, a i ʻole nā winches kaʻa ʻenekinia, koi ʻoi aku ma mua o kahi ʻōlelo. E noi i: nā palapala wili me nā helu wela, nā faila papahana CMM no ka nānā ʻana i ka ʻatikala mua, a me nā hōʻike o ka calibration ʻaoʻao ʻekolu makahiki no nā lako metrology āpau. A laila hoʻohālikelike-ʻaʻole wale ke kumukūʻai, akā kaʻina hana.
A 304 hale hana kila kila ʻO ia ka mea nāna e mālama i ka hana o ka alloy ma lalo o ke kaumaha, e hoʻomalu i nā ʻano like ʻole mai ka heheʻe a hiki i ke ana ʻana, a mālama i kāu kaha kiʻi ma ke ʻano he ʻaelike - ʻaʻole he manaʻo - loaʻa nā kauoha hou. ʻAʻole ma o nā ʻōlelo hoʻohiki. Ma o ka hoʻokō ʻana i hōʻoia ʻia, palapala ʻia, hana hou ʻia.
