Ke kuhikuhi nei nā mea ʻenekinia i nā ʻāpana mea hana galvanizing, ʻaʻole pono lākou i nā ʻāpana wale nō - pono lākou i ka kūpaʻa o ke kūkulu ʻana ma lalo o ka haʻalulu wela, ka paʻa ʻana o ka dimensional ma hope o ka hoʻokomo ʻana i ka zinc, a me ke kūpaʻa ʻana i ka corrosion e mau ana i 25+ mau makahiki i nā kaiapuni ʻoihana ikaika. ʻO ia ke kumu i loaʻa ʻole ai nā kumu paʻa paʻa pololei, nā kino valve kaomi, a me nā wili pahu winch center shaft mai nā kumu kumu nui. No nā hale hana i kūkulu ʻia no ka mana metallurgical-ʻaʻole ka leo.
He aha ka mea e hana ai i kahi hale hana lako lako Galvanizing maoli?
Hana ʻia kahi hale hana mea hana galvanizing maoli ma ke kuʻekuʻe o ka ʻepekema alloy, ka hoʻopaʻa ʻana i ka wela, a me ka geometry hana. ʻAʻole lawa ka hoʻolei ʻana i ka hao a i ʻole ke kila mīkini. Pono ʻoe e wānana i ke ʻano o ka AMS 5387 cobalt alloy i ka wā o ka hoʻoheheʻe ʻana i ka wela: kahi e komo ai ka zinc i ka micro-porosity, kahi e hoʻoulu ai ke koʻikoʻi koena i ka warpage i loko o kahi hale cylinder 120-mm-mānoanoa, pehea e mālama ai nā nozzles-based T800 i ka pololei o ke ala kahe ma hope o 450°C zinc bath.
Ua ʻike mākou i ka poʻe kūʻai e hōʻole i ka 37% o nā ʻāpana ʻāpana mua-ʻaʻole ma muli o ka hewa o ka mīkini, akā no ka mea i hoʻopaʻa ʻia ka ʻili o ke one i ka wai, e hoʻohū ai i ka wā o ka galvanizing. Ua hoʻohana hewa kekahi poʻe i nā kelepona GD&T: e hōʻike ana i ka palahalaha ± 0.05 mm ma ke kahua pahū 600-mm me ka helu ʻole ʻana no ka distortion post-galvanizing. ʻAʻole kali ka hale hana maoli no ka hāʻule. Hoʻohālike ia i ka pōʻaiapuni wela o ka laina galvanizing i ka wā o ka loiloi hoʻolālā - a hoʻoponopono i nā kihi kikoʻī, nā kūlana puka, a me nā kaʻina hana wela e like me ia.
ʻEhā mau mea hiki ʻole ke kūkākūkā
Hāʻawi kahi hale hana mea hana galvanizing pono i kēia mau mana ʻehā - ʻaʻole ma ke ʻano he ʻōlelo kūʻai aku, akā e like me ka mea i kākau ʻia, nā hana hou.
- Hiki ke hiki i ka helu wela: ʻO kēlā me kēia pahu cobalt-nickel, kēlā me kēia hoʻolei hao, kēlā me kēia kumu pāpaʻi kila kila e lawe ana i ka nānā ʻana i nā kemika piha (ASTM E353), nā hōʻike ʻana i ka palaoa, a me ka ʻikepili tensile pre-galvanizing-ʻaʻole wale nā palapala wili.
- Hoʻomalu kaʻina hana ʻano: Ka hoolei one no ka nui geometry + CNC machining no ka sila ili + pana kiʻi ma mua o ka galvanizing no ka pani ʻana i nā pores o ka ʻili—i hana ʻia ma lalo o hoʻokahi hale me nā mea hana like ʻole a me ka hoʻomau ʻana o ka datum i ana CMM.
- Galvanizing-ʻike hoʻopau: ʻAʻohe wili ma hope o ka uhi ʻana i ka zinc. ʻO nā ana koʻikoʻi a pau—nā kaula milo, nā ʻāwīwī O-ring, nā mea pili—ua mālama ʻia *ma mua o ka hoʻoulu ʻia ʻana, me nā ʻae ʻia i hōʻoia ʻia me ka mānoanoa zinc maoli (ana ʻia ma ka ASTM B602 ma nā kākika hoʻāʻo e holo pū ana me ka hana ʻana).
- Ka hōʻoia hana ma mua o nā kaha kiʻi: ʻAʻole "hana" kahi kino valve kaomi i ka wā e hala ai i ka CMM. Ua hōʻoia ʻia me ka hoʻāʻo hydrostatic ma 1.5 × kaomi hana, a laila nānā ʻia no ka zinc adhesion me ka hoʻohana ʻana i nā hoʻāʻo cross-hatch tape (ASTM D3359) ma nā ʻāpana mīkini a me as-cast.
No ke aha e hoʻomalu ai ʻo Cobalt Alloys i nā noi Galvanizing koʻikoʻi
ʻAʻole koho ʻia nā ʻāpana Cobalt-nickel no ka hanohano. Hōʻike ʻia lākou i kahi o ka hāʻule ʻana i ka manawa hoʻomaha, ka pilikia palekana, a i ʻole ka hoʻokuʻu ʻana i ke kaiapuni. Mālama ʻo AMS 5387 cobalt alloy 6 i ka ikaika ma luna o 450 MPa ma hope o 500 mau hola ma 600°C—koʻikoʻi no nā kiwi holo kaʻa ma waena o ka wai kaʻina hana wela a me ka ea ambient ma mua o ka galvanizing. Kū'ē nā nozzles hoʻokumu ʻia ma T800 i ka wā e hoʻopaʻa ʻia ai i nā hui winch vibration kiʻekiʻe, e pale ana i nā micro-cracks i lilo i mau ʻāwaha paʻa zinc.
Akā, koi nā kobalt alloys i ka ʻike - ʻaʻole nā mea hana wale nō. Ua ʻike mākou i nā hale kūʻai e hoʻāʻo e mīkini AMS 5387 me nā mea hoʻokomo carbide maʻamau. Ka hopena? Ua hāʻule ke ola o ka mea hana i ka 80%, ua piʻi ka ʻeleʻele o ka ʻili i Ra 3.2 µm, a ua hana nā micro-tearing i nā hemahema o lalo. ʻAʻole "mea hana maikaʻi aʻe" ka hoʻoponopono. ʻOi aku ka lohi o ka hānai ʻana, ka hāʻawi ʻana i ka mea hoʻoheheʻe cryogenic, a me ka hoʻomaha ʻana i ke kaumaha ma hope o ka mīkini ma 920°C ma mua o ka pau ʻana. Hoʻokaʻawale kēlā pae o ke kaʻina hana i nā loea mai nā mea hoʻolako.
Ke koho ʻana i kāu hoa: Nā nīnau e hōʻike ana i ka hiki maoli
Mai nīnau "Ke hana nei ʻoe i nā ʻāpana galvanizing?" E nīnau i kēia:
- “E hōʻike mai iā mākou i kāu mau hōʻike hoʻāʻo hoʻopaʻa zinc ʻekolu hope loa no nā kumu puna hao hao—ʻo ia hoʻi nā hopena cross-hatch ma nā ʻāpana riser-fed vs.
- "Pehea ʻoe e hōʻoia ai i ke kūpaʻa ʻana o kahi pahu pahu piston pump 420-mm-diameter ma hope o ke galvanizing? Ke hoʻohana nei ʻoe i nā ana kumu i hoʻopaʻa ʻia i nā ana ma hope o ka galvanizing-a i ʻole hilinaʻi i nā ana mua o ke kapa wale?"
- "He aha kāu ʻike silika i ʻae ʻia i loko o ka hao ductile no ka hoʻoheheʻe ʻana i ka pae galvanizing-a pehea ʻoe e hōʻoia ai i kēlā me kēia wela?"
Inā hōʻike nā pane i ka ʻae ʻana i ka ISO 1461 me ka ʻole o ka ʻōlelo ʻana i nā ʻano hōʻoia mānoanoa zinc ASTM A123/A153, e haʻalele. Inā haʻi lākou i ka "hana wela maʻamau" me ka ʻole o ka inoa ʻana i nā pihi manawa / wela wela no kāu huila kikoʻī, e nānā mau.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD.: Kahi e hui ai ka Precision i ka ʻoiaʻiʻo o ka hana.
Ma muli o Qingdao, QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. kūkulu ʻia nā ʻāpana lako hana galvanizing kahi e hālāwai ai ke kumumanaʻo i ka ʻoiaʻiʻo wela. ʻO kāna keʻena hoʻokō ISO e holo ana i ka hoʻopukapuka kālā a me ka hoʻolei ʻana i ke one ma ka ʻaoʻao me ka multi-axis CNC machining-no laila hiki ke hoʻolei ʻia ka nozzle kobalt alloy, hoʻomaʻamaʻa wela, hoʻopau mīkini, a hoʻāʻo zinc me ka ʻole o nā lima lima. Loaʻa i kēlā me kēia kino kīpē puʻe ka hiki ke hoʻopaʻa ʻia. Loaʻa kēlā me kēia kumu paʻa i ka CMM i ka nānā ʻana ma mua a ma hope o ka hoʻohālikelike ʻana. Hoʻouna ʻia kēlā me kēia ʻāpana AMS 5387 me ka palapala ʻāina mānoanoa zinc-ʻaʻole wale nā peʻa paʻa.
ʻAʻole wehewehe ʻia kā lākou hana e nā helu catalog. Ua wehewehe ʻia e ka mea e ola nei: he T800 winch center shaft roller e hana ana i nā hola 18,000 ma nā pahu pahu awa o Asia Hema; he plug AMS 5387 e hoʻopaʻa ana i nā kaapuni hydraulic ma ke Kai ʻĀkau a me ke kinoea skid; he kahua pahū kila kila e paʻa ana i ka pono ma hope o ʻelima mau pōʻaiapili hou i loko o nā mea kanu wai ʻino ʻEulopa.
No ka poʻe ʻenekinia e ʻimi nei i nā mea hana hoʻomeamea i nā hoa hana, ʻaʻole ʻo ka metric ka haʻahaʻa haʻahaʻa loa - ʻo ia ka lōʻihi o ke ola pōʻaiapuni i hōʻoia ʻia. Hoʻomaka ia me ka hoʻopaʻi metallurgical, ʻaʻole ka wikiwiki machining. Ma laila e hoʻomaka ai ka pololei—a ma laila ʻo QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. hāʻawi.
