ʻO ke keleawe keleawe

1. Hōʻikeʻike

Bronze ʻaʻole hoʻokahi mea me ka paʻa paʻa hoʻokahi. I ka hana keleawe-alloy hou, ka ohana keleawe keleawe keleawe, nā keleawe kēpau, nā keleawe kiʻekiʻe alakaʻi, nā keleawe nickel-tin, a me nā keleawe aluminika, a he ʻokoʻa ka haku mele ʻana o kēlā me kēia hui a no laila he ʻokoʻa ka nui.

ʻO ia ke kumu i hoʻomaopopo maikaʻi ʻia ai ka "density of bronze" a Nā haʻona ma mua o ka waiwai hoʻokahi.

2. He aha ke ʻano o ka Density i kahi Alloy Bronze

ʻO ka Density ka nuipaʻa o kahi mea ma kēlā me kēia leo. I ke keleawe, ʻaʻole ia he helu helu helu; he hōʻike pololei ia o ka kemika a me ka microstructure o ka alloy.

ʻO nā mea hao keleawe ma muli o ke keleawe, akā ʻo ka hoʻohui ʻana i ke tini, zinc, aluminum, nickel, mang kāne, 'Eron, a i kekahi manawa, hoʻololi ke kēpau i ka mānoanoa hope loa mai ke keleawe maʻemaʻe.

Loaʻa i ke keleawe ponoʻī ka mānoanoa o 8.89 g / cm³, no laila, ʻoi aku ka māmā o kekahi mau keleawe ma mua o ke keleawe, aʻo nā mea ʻē aʻe e pili kokoke ana i ke keleawe a i ʻole ʻoi aku ka paʻakikī, ma muli o ka ʻohana alloy.

ʻO ia ke kumu he mea nui ka paʻa keleawe i ka ʻenekinia. Pili ia i ke kaumaha hapa, inertia, moku lawe moku, hana mālamaʻia, a me ke ʻano o ke ʻano o ka ʻāpana i ka wili ʻana, e hee ana, a i ʻole lawelawe lawe ukana.

I ka lawe ana a me ka noi moana, ʻo kahi laʻana, ʻAʻole pili wale ka paʻakikī i ka "kaumaha"; he hapa ia o ke koena mechanical a me ka wela o ka mea.

3. No ke aha e ʻokoʻa ai ka Density Bronze ma waena o nā ʻohana

He inoa ʻohana ʻo Bronze, ʻaʻole hoʻokahi kikoʻī alloy. Hoʻokaʻawale ʻia ka ʻohana i nā keleawe keleawe-tini, nā keleawe kēpau, nā keleawe kiʻekiʻe alakaʻi, nā keleawe nickel-tin, a me nā keleawe aluminika.

No ka mea, hoʻohana kēia mau ʻohana i nā ʻōnaehana hoʻohui like ʻole a me nā ʻāpana like ʻole o nā mea hoʻohui, ʻaʻole like ko lākou mau mānoanoa.

ʻO kēia ke kiko metallurgical kī: hoʻololi ka pāpaʻi no ka hoʻololi ʻana o ka alloying i ka nuipa ma kēlā me kēia ʻāpana leo o ka ʻōnaehana waiwai.

ʻAʻole hana like ke keleawe me ka zinc a i ʻole alumini me ke keleawe me ka nui a i ʻole ke kēpau, a ʻaʻole e like ke ʻano o ke keleawe nickel-aluminum me ke keleawe keleawe alakaʻi kiʻekiʻe..

Nā papa waiwai i paʻi ʻia no C90500, C93200, C86300, C95400, a ʻo C95500 e ʻike ʻia kēlā ʻokoʻa ma nā helu maoli ma mua o ke kumumanaʻo wale nō.

4. Nā Waiwai Kūʻai Makaʻāinana o nā Alloy keleawe maʻamau

Hoʻopili ʻia nā kumulāʻau paʻa mai nā ʻikepili alloy i paʻi ʻia ma 20°C / 68° F.

5. He aha ka Bronze Density i ka hoʻolālā a me ka hana ʻana

ʻO ka Density kahi hoʻololi hoʻolālā, ʻAʻole wale he helu Catalog

Ma ke koho keleawe, ʻAʻole he waiwai wehewehe wale nō ka paʻa.

He hoʻololi hoʻolālā e hoʻololi hapa nuipa, inertia, hana mālamaʻia, kaumaha hoʻouna, a me ka pane ikaika, ʻoi aku ka nui o ka ʻāpana, kawili ʻana, a i ʻole e hoʻokē pinepine ʻia a hoʻemi ʻia.

ʻO ia ke kumu e nīnau ʻole ai nā ʻenekinia "Pehea ka paʻa o ke keleawe?"Akā "He aha ka hana o kēia density i ka ʻāpana i pau i ka lawelawe?"

ʻO ka Bronze kahi ʻohana o nā mea hao i hoʻohana ʻia i nā pōʻai hana ʻokoʻa loa, no laila e unuhi mau ʻia ka nui o ka papa UNS i koho ʻia me ka ukana, wikiwiki, lubrication, a me ke kaiapuni.

Mamano, Inertia, a me ka Hana Hana

ʻO ke keleawe ʻoi aku ka ʻoi aku o ke kaumaha no ka geometry like. I ka lako paʻa, ʻAʻole pili a makemake ʻia paha inā hāʻawi ka nui i ka hoʻomoe a i ʻole ka paʻa paʻa.

I nā ʻāpana ʻōwili a pānaʻi paha, Akā naʻe,, hoʻololi ka nuipaʻa i ka inertia o ka ʻōnaehana, e pili ana i ka torque hoʻomaka, hana hooki, pane haʻalulu, a me ka ikehu e pono ai e hooikaika i ka mea.

ʻO kēia kekahi kumu nui o ka paʻa keleawe i nā mīkini, Nā Nele, hanakai, huakai, a me nā ʻāpana ʻē aʻe e pili ana i ka neʻe.

No laila, lilo ka koho density i ʻāpana o ka hoʻolālā mechanical, ʻaʻole wale ka ʻōlelo kikoʻī.

No ke aha he mea nui ka Density i nā Bearings

ʻO Bronze kekahi o nā ʻohana mea lawe maʻamau, akā, ua koho mua ʻia ka huila no kāna hiki ke hoʻouka wikiwiki, ʻano hoʻoluliluli, ʻano ʻaʻahu, a me ka launa pū me ke kumu, ʻaʻole no ka nui wale.

Hoʻomaopopo ka papa hana hoʻolālā keleawe keleawe e pili ana ka hana ʻana i ke ʻano o ka ʻōnaehana i ke kiʻiʻoniʻoni piha., hui-kiʻiʻoniʻoni, a i ʻole ka lubrication palena,

a ua hoʻohana mau ʻia nā bearings keleawe i nā kūlana lohi loa a i ʻole nā ​​​​hoʻouka nui ʻana kahi koʻikoʻi ka maikaʻi o ka lubrication..

Ma ia pōʻaiapili, pili ka pa'apa'a i ka nuipa pono a me ka inertia wela o ka bearing, akā, ʻaʻole ia e pani i nā nīnau koʻikoʻi o ka paʻakikī o ka lāʻau, lako lubricant, a me ke aupuni pili.

ʻO kahi ala kūpono e noʻonoʻo ai i kēia: hiki ke paʻa a paʻa i ka hana keleawe ʻoi aku ke kaumaha, akā, inā ʻilihune ka ʻōnaehana lubrication, ʻAʻole e mālama ka density i ka hoʻolālā.

ʻO ka palapala lawe keleawe ka mea maopopo i ka nui o ka lubrication, Viscosity, a pono ke pololei o ka bearing geometry no ka holo pono o ka bearing. He mea nui ka paʻa, akā i loko o kēlā ʻōnaehana tribological nui aʻe.

ʻO ka Density a me ka Pono Hana Hana

I ka hana ana, ʻoi aku ka nui o ka paona keleawe ma mua o ke kaumaha o ka hapa hope.

Hoʻopilikia pū mea hoohana, hua hoolei no ka pana a ninini paha, Uku kālā, lawe ukana, a me ka ukana machining downstream.

ʻO kahi hoʻoheheʻe nui i hana ʻia mai kahi keleawe ʻoi aku ka nui o ka nui no ka envelopp hoʻokahi, no laila, pono e hoʻoneʻe ka hale hana hale a me ka mīkini i nā metala hou aʻe i kēlā me kēia pae o ke kaʻina hana.

ʻAʻole ia e ʻoi aku ka maikaʻi a ʻoi aku ka maikaʻi o ke keleawe keleawe ma ia iho, akā, hoʻololi ia i ka hoʻokele waiwai o ka hana.

He mea koʻikoʻi kēia i nā mea e like me nā kino valve, mea hoolele, nahelehele, a me nā ʻāpana mīkini hana kaumaha, kahi i hoʻohana mua ʻia ai ka mea hao no ka mea hāʻawi ia i kahi hui maikaʻi o ka ikaika, Ke kū'ē neiʻo Corrosionion, a kau pale.

Nā keleawe alumini nikela, ʻo kahi laʻana, ua wehewehe ʻia he kūpaʻa maikaʻi loa i ka cavitation a me ka hana wai kai ikaika, ʻo ia ke kumu i hoʻokumu ʻia ai lākou i ka lawelawe kai.

Ma ia mau hihia, ʻae pinepine ʻia ka uku hoʻopaʻi no ka mea ʻoi aku ka nui o ka pono lawelawe ma mua o ke kumukūʻai kaumaha.

ʻO ka Density Versus Porosity: He Hooko Ko'iko'i

I ka hana keleawe, he maalahi ka huikau mānoanoa nui me ʻāpana ʻāpana.

ʻAʻole like lākou. ʻO ka paʻa o ka waiwai kahi waiwai o ka alloy ponoʻī; pili ka ʻāpana ʻāpana i ka alloy, ke ala kaʻina hana, a me kekahi porosity i loko o ka mea i pau.

He mea koʻikoʻi kēia ʻokoʻa i nā ʻāpana keleawe metalalurgy pauka, kahi i hoʻohaʻahaʻa ʻia ai ka mānoanoa sintered ma mua o ka piha piha i hiki i ka ʻāpana ke mālama i ka ʻaila.

Hoʻomaopopo ka palapala keleawe-alloy e hiki ke komo i nā ʻāpana keleawe P/M 10% i 30% ma ka nui o ka aila ma muli o ka nui o ka sintered, ʻo ia ke kumu e hana ai nā bearings keleawe ponoʻī i nā haʻahaʻa haʻahaʻa.

He waiwai kēlā wahi ma mua o ka pauda metallurgy. Hoʻomanaʻo ia i nā ʻenekinia ʻaʻole pili wale ka density i ke kaumaha; pili pū nō hoʻi i ka hale o loko, kaʻana like, a me ka porosity hana.

I nā'ōlelo'ē aʻe, ʻO ka "haʻahaʻa haʻahaʻa keleawe" he koho hoʻolālā paha a he kīnā paha, ma muli o ke ala kaʻina hana. He mea nui ka hoʻomaopopo ʻana i kēlā ʻokoʻa no ka mālama ʻana i ka maikaʻi.

Pehea e hoʻohana pono ai nā ʻenekinia i ka Density

He maʻalahi ke kaʻina hana kūpono akā ʻike pinepine ʻia.

Ka mua, hoakaka i ka pololei UNS pae keleawe. Ka lua, hōʻoia inā pili ka waiwai mea hoolei paa loa, mea i hanaia, a i ʻole nā ​​mea P/M sintered.

Ke kolu, e nānā inā pili ka hoʻolālā i ka lehulehu, inertia, Kauhini, a i ʻole ka paʻa ʻana o ka lubricant.

A laila pono e hoʻohana ʻia ka density ma ke ʻano o ka hoʻoholo koho. ʻO kēia wale nō ke ala e pale aku ai i ka hoʻohana ʻana i ka helu catalog me he mea lā he pane ʻenekinia piha.

6. Pehea e hoʻohana pono ai nā ʻenekinia i ka ʻikepili Density

ʻO ke ala kūpono o ka hoʻohana ʻana i ka density keleawe ʻo ia ke kuhikuhi i ka huikau pololei, ʻaʻole wale ka huaʻōlelo "bronze."

ʻO ke keleawe kalaiwa e like me C93200 he ʻokoʻa like ʻole mai kahi keleawe alumini e like me C95400, a hiki i kēlā mau ʻokoʻa ke hoʻololi i ka nui o ka ʻāpana i kahi hoʻolālā hana.

No laila, pono nā helu data ma luna wale nō ke hoʻopaʻa ʻia lākou i kahi helu UNS kikoʻī a me ke ʻano huahana.

Pono e hoʻomanaʻo nā ʻenekinia ʻaʻole i hoʻoholo ka density i ka hana ponoʻī.

ʻOkoʻa loa ke ʻano o nā keleawe ʻelua me nā ʻano like, Kuupuiawi, markinpalibility, a i ʻole hiki ke hoʻouka.

ʻo kahi laʻana, Aia ʻo C95500 a me C86300 ma kahi o 7.5–7.8 g/cm³., akā hoʻohana ʻia lākou i nā niches lawelawe koʻikoʻi no ka mea ʻokoʻa kā lākou chemistries a me nā profile mechanical.

7. Loko koho: Ke koho ʻana i ka Bronze Pono e ka Density a me ka hana

Inā pili ka ho'ēmi kaumaha, ʻO nā keleawe alumini e like me C95400 he mea maikaʻi loa ia no ka mea e noho ana lākou ma ka ʻaoʻao māmā o ke aniani keleawe ʻoiai e hāʻawi mau ana i ka corrosion ikaika a me ka hana hana..

No ka halihali kaumaha a i ʻole nā ​​lako kai, hiki i ka ʻenekinia ke ʻae i ke keleawe ʻoi aku ka nui, e like me C93200 a i ʻole C86300, no ka mea, ʻoi aku ka maikaʻi o ka lawelawe ma mua o ka hoʻopaʻi lehulehu.
Inā ʻo ka palapala noi he ʻoihana moana lawelawe koʻikoʻi a i ʻole nā ​​lako pili propeller, ʻO nā keleawe alumini nickel e like me C95500 e hāʻawi i kahi hoʻololi ikaika ma waena o ke kaumaha, ikaika, a me ke kū'ēʻana.

No laila, maʻalahi ka lula koho: mai koho i ke keleawe ma ka nui wale.

E koho i ka alloy nona ka nui, ikaika, E kāʻei i ke kū'ē, Ke kū'ē neiʻo Corrosionion, whola, a me ka machinability hui pu i ka hana o ka hapa.

He mea nui ka paʻa keleawe, akā, hoʻokahi wale nō axis i loko o ka hoʻoholo mea hoʻololi nui.

8. Bronze Density vs. Mea hoʻokūkū

9. Hopena

ʻOi aku ka maikaʻi o ka hoʻopaʻa ʻana o ke keleawe e like me a waiwai ʻohana me ka laulā ākea, ʻaʻole ma ke ʻano he waiwai paʻa hoʻokahi.

Loaʻa nā hui keleawe mai kahi kokoke 7.45 g / cm³ i ke keleawe aluminika i 9.25 g / cm³ i ke keleawe keleawe alakaʻi kiʻekiʻe, me kekahi mau keleawe maʻamau e noho ana ma waena.

Hōʻike ʻia kēlā laha i ka ʻoiaʻiʻo he ʻohana keleawe keleawe me nā ʻōnaehana hoʻohui like ʻole a me nā lawelawe lawelawe ʻē aʻe..

No nā Engineers, maopopo ka haawina hana: pili ka nui o ke keleawe i ka nuipa, inertia, Ka Hoʻoulu, a me ke kaulike, aka, e unuhi mau ia me ka ikaika, ʻano ʻaʻahu, Ke kū'ē neiʻo Corrosionion, a me ka mea hana.

ʻO ke keleawe "maikaʻi" ʻaʻole ia ka māmā a i ʻole ke keleawe kaumaha loa; ʻo ia ke keleawe i kūpono i ke koena o ka pōkole hoʻolālā.

 

FaqS

Ua ʻoi aku ke kaumaha o ke keleawe ma mua o ke keleawe?

Aole mau. Loaʻa i ke keleawe ka mānoanoa o 8.89 g / cm³, ʻoiai ke ʻano like ʻole ka density keleawe e ka alloy. ʻOi aku ka māmā o kekahi mau keleawe ma mua o ke keleawe, ʻOiai e kekahi, e like me C93200, ua oi iki aku.

ʻOi aku ka maikaʻi o ke keleawe?

ʻAʻole. Hiki ke kōkua i ka ho'ēmi kaumaha, akā, e noʻonoʻo pono ke koho keleawe i ka ikaika, E kāʻei i ke kū'ē, Ke kū'ē neiʻo Corrosionion, whola, a me ka hana machining.

No ke aha i loaʻa ai nā ʻano like ʻole o nā ʻāpana keleawe?

No ka mea, he ʻohana keleawe ka keleawe me nā ʻōnaehana hoʻohui like ʻole - tin, alakaʻi, nickel, aluminum, mang kāne, a me ka hao e hoʻololi i ka nui hope a me ka lawelawe lawelawe.
