He mea koʻikoʻi ka ʻōnaehana kānana i nā mīkini i hele mai kekahi mai ka hale hana.Akā ʻokoʻa nā kūlana hana, a i ke ʻano o nā mīkini nui, he mea maʻamau ia e pili pū me nā kūlana koʻikoʻi.Hoʻokomo ʻia i loko o nā ao ʻeleʻele o ka lepo pōhaku- e like me ka mining-a me ka honua i loko o nā mīkini mahiʻai a me nā ululāʻau a i ʻole nā koena ohu mai ka puhi ʻana o ka ʻenekini- e like me nā kaʻa a me nā kaʻa kaʻa- noi ʻia kēia mau waiwai ma nā ʻano he nui ʻole e ka lewa a me ka hana ponoʻī.
No ka hōʻoia i ka holo ʻana o ka ʻōnaehana ma nā pae maikaʻi loa, pono e loaʻa nā ʻōnaehana kānana like ʻole.E ʻike ma lalo he aha ka ʻokoʻa ma waena o kahi kānana ʻili a me kahi kānana hohonu a me ke kuleana o kēlā me kēia mea e kōkua iā ʻoe e hoʻokō i kāu mau hopena.
He aha ke kānana ili?
Ua ʻike mua mākou ʻo nā kānana no nā mīkini nui nā mea pili i nā ʻōnaehana kahe wai like ʻole: ea, lubricant a me ka wahie.No laila, no ka hoʻokō pono ʻana o ke kaʻina kānana, pono ke ʻano kānana, ʻo ia hoʻi, ka mea e hoʻopaʻa ai i nā mea hoʻohaumia.
Nui nā ʻano mea e hana ai i nā mea kānana: cellulose, polymers, fiberglass, a me nā mea ʻē aʻe.Pili ka mea i ke kumu.I ka kānana ʻana i nā lubricants i nā ʻenekini puhi, no ka laʻana, maʻamau ka hoʻohana ʻana i nā kānana pepa.Ma ka microfiltration, ma ka ʻaoʻao ʻē aʻe, hoʻohana nui ʻia ka microfiber aniani.
I ka pōkole, ʻo ka kānana ke kaʻina hana e koi ai i ka hele ʻana o kahi wai a i ʻole ke kinoea ma o kahi mea porous i mea e wehe ai i nā mea paʻa i hoʻokuʻu ʻia ma laila.Inā like ka mānoanoa o ka mea kānana me ka nui o nā ʻāpana e unuhi ʻia, ua kapa ʻia ke kaʻina hana filtration ili, no ka mea ua paʻa ka mea ma ka ʻili kānana.He mea maʻamau ka loaʻa ʻana o nā kānana ea o kēia ʻano hoʻohālike.
ʻO kekahi hiʻohiʻona maʻamau o ka kānana ili he sieves.I kēia hihia, hoʻopaʻa ʻia nā ʻāpana ma luna o ka ʻili, hana i ka keke a ʻae i nā ʻāpana liʻiliʻi e hele i loko o ka pūnaewele kānana.Nui nā ʻano o nā kānana ili.
He aha ke kānana hohonu?
I loko o ka kānana hohonu, ʻokoʻa i ka kānana ʻili, ua hoʻokaʻawale ʻia nā ʻāpana paʻa ma ka waiho ʻana i loko o nā pores o ke kānana kānana, hiki ke komo i:
1. ʻO kahi moena o nā ʻanoʻano coarser (no ka laʻana, 0.3 a 5 mm ka hohonu o ke one).
2.A few centimeters layer of fiber (cartridge filters i silaʻia me resins, no ka laʻana).
3.Leaves he mau millimeters manoanoa (no ka laʻana, kānana media i hana ʻia me ka cellulose).
4. ʻO kahi papa kākoʻo granular i ka kānana nui (ka papa hana mua, no ka laʻana).
Ma kēiaʻano,ʻo ka mānoanoa o ka mea kānana ma kahi o 100 manawaʻoi aʻe ma mua o ka nui o ka'āpana e hoʻopiliʻia, i ka wā e pili ana i nā kānana hohonu.Hiki iā lākou ke lilo i pahu uea, fiber agglomerates, porous plastic a me nā metala sintered.No laila, hoʻokumu ʻia nā kānana hohonu e kahi ʻupena microfibers o ka granulometry liʻiliʻi loa, a hiki i kahi e paʻa ai nā ʻāpana microscopic.ʻO kēia hiʻohiʻona ka mea e hōʻoiaʻiʻo ai ʻaʻole hiki ke kānana ma ka ʻili wale nō, akā i ka hohonu ma o nā media kānana āpau.Hiki i kēia ke komo i nā polymers, cellulose a i ʻole fiberglass, i hoʻokaʻawale ʻia a i haku ʻia.
No laila, ma ka kānana hohonu, hele nā mea haumia i kahi ʻano "labyrinth" i loko o ka hāmeʻa, e hoʻopili ʻia i loko o nā microfibers interlaced i hana i ka ʻupena kānana.ʻO nā kānana hohonu he mau pepa i pelu ʻia i nā mānoanoa like ʻole, no laila e hana ana i kahi ʻili kānana nui aʻe ma kahi like, ke hoʻohālikelike ʻia me nā kānana ʻili o ka nui like.
ʻO kēia ka pōmaikaʻi nui o ka kānana hohonu, no ka mea e lōʻihi ka hoʻopiha ʻana (clog).I loko o ka kānana hohonu, ua hoʻokumu ʻia ka keke kānana, pono e hoʻoneʻe ʻia i kēlā me kēia manawa e pale ai i ka clogging, leaks a i ʻole ka hāʻule ʻana i ke kaʻina hana.E hoʻokumu ʻia ka pai a hiki i ke kānana i ka saturation.Ma kekahi mau hiʻohiʻona kānana wahie, hiki ke hoʻomaʻemaʻe i kekahi mau manawa me ka ea paʻa a i ʻole ka aila diesel ma mua o ka hoʻololi ʻana iā lākou.
He aha ka ʻokoʻa ma waena o lākou?
Ma nā hihia ʻelua, ʻo nā kaʻina hana kino e pili ana: ka interception pololei, ka hopena inertial, diffusion a me ka sedimentation.I loko o ka kānana ili, akā naʻe, ʻo ka hui ʻana o nā mīkini kānana he hui a kānana paha.I ka hihia o ka kānana hohonu, he entanglement.
ʻOiai ʻoi aku ka maikaʻi o nā kānana hohonu, ʻo ka hōʻike ʻana o ka kānana ʻoi aku ka maikaʻi ma kēlā me kēia hihia.No ka mea he ʻenehana ʻoi aku ka maikaʻi, ʻoi aku ka maikaʻi o ka hoʻohana ʻana i nā kānana hohonu i ke ʻano o nā ʻōnaehana i ʻoi aku ka maʻalahi o ka haumia, e like me nā ʻōnaehana hydraulic.
