He aha ka mea ea aila

 

Hāpai, Ke manaʻoʻiʻo nei au e kamaʻāina nā mea a pau, ʻo kā mākou bearing wili i hoʻohana pinepine ʻia ka mea maʻamau loa, he ʻāpana koʻikoʻi ia o nā mīkini a me nā lako o kēia wā. No laila he aha ka bearing ea?

 

Ke kūlou kinoeaʻO ka ea ka mea hoʻoluʻu kinoea i hoʻohana pinepine ʻia, akā hiki ke hoʻohana ʻia ka naikokene, argon, hydrogen, helium a i ʻole carbon dioxide e like me ka mea e pono ai.

 

I loko o nā compressors gas, nā mea hoʻonui a me nā circulators, hoʻohana pinepine ʻia ka mea hana e like me ka lubricant.

 

ʻO ke ea e pili ana i ke ea e kākoʻo ana i ka ukana me ke kōkua o ke kiʻiʻoniʻoni ea kaomi i hoʻokumu ʻia ma waena o ka ʻili o ka pālua paheʻe ea, a ua hoʻokaʻawale loa ʻia ka ʻili o ka pālua paheʻe e ke kiʻiʻoniʻoni ea i ka wā e hana ana.

 

No nā bearings ea nā bearings paheʻe wai i loko o nā bearings paheʻe, kahi i lubricated wai ʻia i ka wā e hana ana, a ʻo kā lākou mea lubricating medium he ea.

 

Ka hoʻokaʻawale ʻana o nā bearings ea

Wahi a ke ʻano hana o ka ʻili ea kaomi, ua māhele ʻia nā bearings ea i ʻelua mau ʻāpana: nā bearings aerodynamic a me nā bearings aerostatic.

 

Hoʻokumu ʻia ka ʻili ea kaomi o ka bearing aerodynamic ma ka lawe ʻana mai i ka ea i loko o ka wahi o ka hui ʻana ma waena o nā ʻili o nā hui paheʻe ma o ka neʻe like ʻana o nā hui paheʻe, a he ʻano wedge ke ʻano o ka ʻili ea. ʻOiai ʻaʻole pono nā bearings aerodynamic i kahi kumu ea o waho, ua kapa ʻia lākou he "mau bearings hana ponoʻī".

 

Hoʻokumu ʻia ka ʻili ea kaomi o ka bearing aerostatic e ka ea i hoʻopaʻa ʻia o waho e hoʻokomo ʻia ana ma o ka throttle ma waena o ka ʻili o ka pālua paheʻe. Pono nā bearings aerostatic i kahi lako ea waho maʻemaʻe.

 

Nā hiʻohiʻona o ka ea

(1) Ke kū'ē haʻalulu haʻahaʻa loa

 

ʻOiai ʻoi aku ka haʻahaʻa o ka mānoanoa o ke kinoea ma mua o ka wai, ʻo ka mānoanoa o ka ea ma ka mahana o ka lumi he 1/5000 wale nō o ka ʻaila mechanical No. 10, a ʻo ke kūpaʻa friction o ka bearing e pili pono ana i ka viscosity, no laila ʻoi aku ka haʻahaʻa o ka friction o nā bearings kinoea ma mua o nā bearings lubricated wai.

 

(2) ʻO ka laulā o nā wikiwiki kūpono

 

Haʻahaʻa ke kūpaʻa ʻana o ka bearing kinoea, haʻahaʻa ka piʻi ʻana o ka mahana, a ʻaʻole iʻoi aku ka piʻi ʻana o ka mahana ma mua o 20 ~ 30 °C ke kiʻekiʻe ka wikiwiki i 50,000 rpm, a ʻoi aku ka wikiwiki i 1.3 miliona rpm. Hiki ke hoʻohana ʻia nā bearings hydrostatic no nā wikiwiki haʻahaʻa loa, a hiki i ka wikiwiki ʻole.

 

(3) ʻO ka laulā o nā mahana kūpono

 

Noho kinoea i loko o ke kinoea ma luna o nā ʻano mahana like ʻole, a ʻo kona mānoanoa ua hoʻopilikia iki ʻia e ka mahana (piʻi iki ka mānoanoa i ka piʻi ʻana o ka mahana, e laʻa me 20°C a i 100°C, piʻi ka mānoanoa o ka ea ma 23%), no laila hiki ke hoʻohana ʻia nā bearings kinoea ma kahi pae mahana o -265°C a i 1650°C.

 

(4) Ka hiki ke hāpai haʻahaʻa

 

Ua like pololei ka mana o ke kaulahao hydrodynamic me ka viscosity, a ʻo ka mana o ke kaulahao pneumatic he mau tausani wale nō o ka nui like o ke kaulahao hydrodynamic. Ma muli o ke kaomi ʻana o ke kinoea, aia kahi palena i ka mana o ke kaulahao kinoea dynamic, a hiki ke hoʻonui ʻia ka ukana ma kēlā me kēia ʻāpana i manaʻo ʻia i 0.36 MPa wale nō.

 

(5) Nā koi pololei o ka hana kiʻekiʻe

 

I mea e hoʻomaikaʻi ai i ka hiki ke halihali ukana a me ka paʻakikī o ka ʻili ea o nā bearings kinoea, hoʻohana pinepine ʻia ka ʻokoʻa o ka bearing (emi ma mua o 0.015 mm) ma mua o nā bearings i hoʻoluʻu ʻia i ka wai, a pono e hoʻomaikaʻi ʻia ka pololei o nā ʻāpana.

 

Ka hoʻohana ʻana o nā bearings ea

ʻO ka ea bearing kahi ʻano hou o ka bearing e hoʻohana ana i ka ikehu hiki ke ea e hoʻokani i kahi hana kākoʻo.

 

ʻO ka ea wale nō ka lubricant i hoʻohana ʻia; No laila, kūpono ka ʻenehana hali ea no nā ʻāpana hana e pono e kaʻawale mai ka haumia a i ʻole no nā wahi hana.

 

I loko o nā bearings ea, ua pani ʻia nā pōpō e nā uluna ea. ʻO kekahi paha o nā noi kaulana loa no nā bearings ea ʻo ia ka hovercraft.

 

Puhi ka peʻahi nui i ka ea ma lalo o ka mokulele hovercraft, e ālai ana i ka puka ʻana o ka ea ma o kahi "ʻaʻahu" laholio elastic. Kākoʻo ke kaomi ea kiʻekiʻe i hana ʻia ma lalo o ka mokulele hovercraft i ke kaumaha o ka ʻili a pēlā e lana ai ma luna o ka uluna ea.

 

Ke lilo nei ka hoʻohana ʻana o nā bearings kinoea i mea ākea a ua aʻo nui ʻia. I kēia manawa, hiki ke hoʻohana ʻia nā bearings kinoea i nā mīkini lole, nā mīkini uwea, nā mea hana mīkini, nā gyroscopes, nā mea hoʻokaʻawale centrifugal wikiwiki, nā wili niho, nā pahu hau e holo ana i nā mahana haʻahaʻa, nā mea hoʻonui hydrogen a me nā mea hoʻopuni kinoea e holo ana i nā mahana kiʻekiʻe.
