Keleawe i hoʻoheheʻe ʻia: Nā Waiwai Mechanical Kiʻekiʻe no nā Valves, Fittings, a me nā Lako Paʻa

Ma nā ʻoihana ʻenekinia kikoʻī e koi ana i nā ʻāpana e kū i ke kaomi kiʻekiʻe, ka ʻaʻahu, a me nā wahi ʻino,keleawe i hoʻoheheʻe ʻia (ʻo C37700/CZ108 keleawe hana mua a i ʻole C46400 keleawe moana) ua hoʻokumu iā ia iho ma ke ʻano he mea i koho ʻia. ʻO nā kaʻina hana hana wela—make-open, make-closed, a i ʻole impression-die—hoʻomaʻemaʻe i ka microstructure keleawe alpha-beta, e hoʻohālikelike ana i ke kahe o ka palaoa no ka ikaika kupaianaha, ka ductility, a me ke kū'ē ʻana i ka luhi. I ka hoʻopaʻa ʻana o nā kūlana honua i ka hoʻokō ʻole ʻana i ke kēpau (NSF/ANSI 372) a me ke kūpaʻa, hāʻawi ke keleawe hana mua i ka hana RoHS-compliant me ka hiki ke hana hou maikaʻi loa, e lilo ia i mea nui no ka kaohi wai koʻikoʻi a me nā noi kūkulu.

Hōʻike kēia ʻatikala i nā ʻano maʻamau o ke keleawe i hoʻoheheʻe ʻia, ko lākou mau pono hana, nā ʻoihana mua, nā pono waiwai, a no ke aha e hiki ʻole ai ke hoʻololi ʻia ke keleawe i hoʻoheheʻe ʻia i nā hiʻohiʻona e koi ana i ka mīkini kūpono a me ka lōʻihi.

Nā ʻāpana keleawe i hoʻoheheʻe ʻia e like me nā kino valve, nā mea hoʻopili, nā kaola, a me nā lako mīkini no ka plumbing, moana, a me nā noi ʻoihana.

Nā ʻAno Maʻamau o ke keleawe i hoʻoheheʻe ʻia a me kā lākou mau kuleana ʻenekinia

Kūlike ke keleawe i hoʻoheheʻe ʻia me nā kūlana ASTM B283/B283M a me EN 12420, e hoʻokō ana i nā densities >99% me nā nui o ka palaoa i kāohi ʻia (ASTM E112 No. 5–7):

1. Nā Kaola a me nā Koʻokoʻo i Hoʻoheheʻe ʻiaʻO nā ʻāpana poepoe, hexagonal, a pālahalaha paha i hoʻohana ʻia ma ke ʻano he preforms no ka mīkini lua. Hoʻonui ke kahe ʻana o ka palaoa kuhikuhi i ka ikaika tensile (400–550 MPa) a me ke kū'ē torsional i loko o nā ʻau a me nā mea hoʻohui.
2. Nā Kino a me nā Mea Hana Valve i Hoʻoheheʻe ʻiaNā hana hoʻopaʻa make pani ʻia no nā kiwikā pōpō, nā kiwikā puka, nā kuʻekuʻe lima, a me nā tees. ʻOi aku ka paʻa o ke kaomi (a hiki i ka 1000 psi) a me ka kūpaʻa pale leak i nā hui wili a i ʻole brazed.
3. Nā Apo a me nā Flanges i Hoʻoheheʻe ʻiaʻO nā forgings i ʻōwili ʻia a i ʻole i hoʻokiʻekiʻe ʻia e hāʻawi ana i ka ikaika hoop like. He mea koʻikoʻi no nā sila, nā couplings, a me nā lako moana ma lalo o ka ukana cyclic.
4. Nā ʻāpana i hana ʻia ma ke ʻano maʻamauNā ʻāpana kokoke i ke ʻano ʻupena e like me nā cylinders laka, nā kia, a me nā synchronizers kaʻa me nā hiʻohiʻona paʻakikī a me ka liʻiliʻi o ka ʻōpala mea.

ʻO kēia mau ʻano, me nā kiwikā keleawe i hoʻoheheʻe ʻia,nā mea hana keleawe i hoʻoheheʻe ʻia, a menā ʻāpana keleawe i hana ʻia ma ke ʻano maʻamau, kākoʻo i ka pololei kiʻekiʻeʻO ka mīkini CNCno nā hoʻomanawanui paʻa.

Nā ʻoihana koʻikoʻi e hilinaʻi nei i ke keleawe i hoʻoheheʻe ʻia

ʻOi aku ka maikaʻi o ke keleawe i hoʻoheheʻe ʻia ma nā ʻāpana koi:

• Ka Mana Wai a me ka Paipu→ Nā kiwikā wai inu, nā mea hoʻopaʻa kaomi, a me nā manifolds.
• Moana a me ke Kai Kūʻono→ Nā mea hana keleawe moana i kū i ka dezincification wai kai.
• Kaʻa a me ka Halihali→ Nā apo Synchro, nā ʻāpana ʻōnaehana wahie, a me nā mea hoʻopaʻa paleki.
• Nā Lako Hana ʻOihana→ Nā laka, nā ʻami, a me nā mea paʻa kūkulu hale.
• ʻAila a me ke Kinoea→ Nā kino kiwikā haʻahaʻa-kaomi a me nā mea hana.

Nā Pōmaikaʻi Koʻikoʻi a me ka Hiki ʻole ke Hoʻololi

Hoʻololi ka hana ʻana i ke keleawe i loko o kahi metala hana kiʻekiʻe:

• Ka Makini Kūikawā→ ʻO nā waiwai ʻoki manuahi (ʻano C36000) e hāʻawi i nā hoʻopau ʻili maikaʻi loa a me ka kaohi ʻāpana, e hōʻemi ana i nā kumukūʻai hana.
• Ka ikaika a me ke kūpaʻa i hoʻonui ʻia→ Ikaika huahua 150–350 MPa me ke kūpaʻa hopena maikaʻi loa i hoʻohālikelike ʻia me ke keleawe i hoʻolei ʻia.
• Ke kū'ē ʻana i ka palaho a me ke komo ʻana→ Ua kāohi ʻia ka dezincification ma nā pae admiralty/moku; ʻoi aku ka maikaʻi o ka alumini i nā kūlana saline.
• Hoʻokō ʻole me ke alakaʻi→ Hoʻokō nā mea hoʻohuihui haʻahaʻa-kēpau a i ʻole bismuth-alloyed i nā lula wai inu.
• Nā Waiwai Nani a me ke Kani→ Hoʻopau gula i wili ʻia a me ke ʻano leo no nā hana hoʻonaninani a me nā mele.

No ke aha e mau ai ke keleawe i hoʻoheheʻe ʻiaʻO nā koho ʻē aʻe i hoʻolei ʻia e loaʻa ka porosity a me nā waiwai kūlike ʻole, ʻoiai ʻo ka waihona ʻauamo mīkini e hoʻopau i ka mea. ʻAʻohe paʻakikī o ke keleawe maʻemaʻe no nā pilina wili, a hoʻonui ke kila kila i ke kaumaha/kumukūʻai me ka conductivity thermal haʻahaʻa. I loko o nā kino valve, nā lako moana, a i ʻole nā ​​​​​​mīkini laka e pono ai ke kaula pololei, ka pono o ke kaomi, a me ke kūpaʻa ʻana i ka corrosion lōʻihi ma lalo o ke kaumaha mechanical, hāʻawi ke keleawe i hoʻoheheʻe ʻia i ka hui kū hoʻokahi o ka formability, ka ikaika, a me ka hoʻokele waiwai ʻaʻole e kūlike kekahi pani me ka ʻole o ka hoʻolālā hou ʻana a i ʻole nā ​​​​​​kūʻai hana.

Nānā: Keleawe i hoʻoheheʻe ʻia i ka hana pololei a me ka hoʻomau

I ka hoʻohana ʻana o nā ʻoihana i nā hybrids hana hoʻohui a me nā kauoha zero-lead, ua lilo ke keleawe i mea kumu no nā ʻāpana hilinaʻi a hana hou ʻia.

Hāʻawi mākou i nā hiki ākea i nā kaola keleawe i hoʻoheheʻe ʻia me ka wela, nā kiwikā, nā mea hoʻopili, a me nā ʻāpana maʻamau me ka palapala hōʻoia piha a me nā lawelawe hoʻopau. E ʻimi i kā mākoupapa inoa keleawe i hoʻoheheʻe ʻia or e hoʻokaʻaʻike aku i kā mākou hui ʻenekiniano nā hoʻonā kūikawā i nā ʻōnaehana wai a i ʻole nā ​​​​papahana lako.

Ke hoʻomau nei ke keleawe i hoʻoheheʻe ʻia i ka hāʻawi ʻana i ka hana i hōʻoia ʻia kahi e pono ai ka pololei a me ke kūpaʻa.
