Nā sila mechanical

Mea hana mechnical sila hana yiwu nui wepa laholio huahana huahana poe

Ke hilinaʻi nei nā sila mechanical e hana ana i ka wai waena wai i ke kiʻi wai i hoʻokumu ʻia e ka wai waena ma waena o nā papa hakakā o ka neʻe a me nā kū paʻa no ka lubrication. No laila, pono e mālama i ke kiʻi ʻoniʻoni ma waena o nā papa hakakā e hōʻoia i ka hana paʻa o ka sila mechanical a hoʻolōʻihi i kona ola lawelawe.

Wahi a nā kūlana ʻokoʻa, ʻo ka hakakā ma waena o nā apo ikaika a kūpaʻa o ka sila mechanical e like me kēia:

(1) paio maloʻo:

ʻAʻohe wai e komo i ka ʻāneʻe gesure, no laila ʻaʻohe kiʻi ʻoniʻoni, ʻo ka lepo wale nō, ʻāpana oxide a me nā mole kinoea adsorbed. Ke holo nei nā apo neʻe a kūpaʻa hoʻi, ʻo ka hopena e wela ka ʻili friction a mae, a hopena i ka liu ʻana.

(2) lubrication palena:

Ke piʻi aʻe ke kaomi ma waena o ke kani o ka neʻe a me ke kū a i ʻole hiki i ka wai ke hana i kahi kiʻi ʻoniʻoni ma ka ʻaoʻao friction he maikaʻi ʻole, e huki ʻia ka wai mai ka hakahaka. Ma muli o ka pālahalaha ʻole o ka ʻili, akā kaulike ʻole, aia ka launa pū i ka puʻupuʻu, ʻoiai ke mālama ʻia nei ka hana lubrication o ka wai i ka hoʻomaha, a ʻo ka hopena ka lubrication palena. ʻO ke komo a me ka wela o ka lubrication palena he kaulike.

(3) Semi-wai lubrication:

Aia kahi wai i ka lua o ka papa heʻe, a mālama ʻia kahi kiʻi ʻoniʻoni lahilahi ma waena o nā papa hoʻopili, no laila maikaʻi nā hoʻomehana a me nā ʻaʻahu. Ma muli o ke kiʻi ʻoniʻoni ma waena o ke kani o ka neʻe a me ke kū i ke kūpaʻa o ka ʻilikai ma kāna puka, ua kaupalena ʻia ka liu ʻana o ka wai.

(4) Hoʻopiha wai piha:

Ke lawa ʻole ke kaomi ma waena o nā kūpeʻe neʻe a kūpaʻa hoʻi, a hoʻonui ka hakahaka, mānoanoa ke kiʻi ʻoniʻoni, a ʻaʻohe pilina paʻa i kēia manawa, no laila ʻaʻohe hanana friction. Eia nō naʻe, i kēia hihia, nui ka hakahaka ma waena o ke apo neʻe a me ke apo kūpaʻa, no laila ʻaʻole hiki ke hoʻokō ʻia ka hopena sila a koʻikoʻi ka liu. ʻAʻole ʻae ʻia kēia ʻano kūlana i ka noi hana (koe wale no ka sila mechanical o ka membrane kāohi ʻia).

ʻO ka hapa nui o nā kūlana hana ma waena o nā apo ikaika a kūpaʻa hoʻi o ka sila mechanical i ka lubrication palena a me ka lubrication semi-wai, a hiki i ka lubrication semi-wai ke loaʻa i ka hopena sila maikaʻi loa ma lalo o ke kūlana o ka coefficient liʻiliʻi loa, ʻo ia hoʻi, nā lole a me ka wela maikaʻi. hanauna.

I mea e hana ai ka sila sila mechanical ma lalo o nā kūlana lubrication maikaʻi, nā mea e like me ke ʻano waena, kaomi, ka mahana a me ka wikiwiki wikiwiki e noʻonoʻo pono ʻia. Eia nō naʻe, ke koho ʻana i ke kaomi kūpono ma waena o nā apo neʻe a kūpaʻa hoʻi, ka hana lubrication kūpono a me ka hoʻomaikaʻi ʻana i ka maikaʻi o ka pae o ka hoʻoneʻe a me nā kūpaʻa paʻa kekahi mau mea nui e hōʻoia i ka hana pono o ka sila.

Nā kūkulu he nui no ka hoʻoikaika ʻana i ka lubrication

1. Pau ka maka eccentricity:

I nā sila mechanical maʻamau, ke kikowaena o ke apo e neʻe ana, ke kikowaena o ke apo kū a me ka laina waena o ka ʻau i kahi laina pololei. Inā ke kikowaena waena o kekahi o nā apo e neʻe a i ʻole ke apo paʻa e hana ʻia e offset ʻia mai ka laina waena o ka lāʻau e kahi mamao, hiki ke lawe mau ʻia ka wai lubricating i loko o ka pae kahe ke hoʻololi ke apo no ka lubrication.

Pono e kuhikuhi ʻia ʻaʻole e nui ka nui o ka eccentricity, keu hoʻi no ke kaomi kiʻekiʻe, e hoʻonāukiuki ka eccentricity i ka maka o ka hopena a me ka lole kaulike ʻole. No nā sila wikiwiki, ʻaʻole kūpono e hoʻohana i ke apo neʻe e like me ke apo eccentric, inā ʻaʻole e haʻalulu ka mīkini ma muli o ke kaulike o ka centrifugal force.

2. Ke kau ʻana i ka maka hope:

He paʻakikī no nā mīkini kiʻekiʻe a me ka wikiwiki e mālama i ke kiʻi ʻoniʻoni ma waena o nā papa kūpikipiki, kahi e luku pinepine ʻia e ka wela kūpikipiki i hoʻokumu ʻia e ke kiʻekiʻe kiʻekiʻe a me ka wikiwiki wikiwiki. I kēia hihia, maikaʻi loa e lawe i ka grooving e hoʻoikaika i ka lubrication. Hiki ke hoʻopili ʻia ke apo neʻe a me ke apo kūpaʻa, i hana mau ʻia i nā mea pale-pale. ʻAʻole pono e hoʻokuʻu ʻia ke apo neʻe a me ke apo paʻa i ka manawa like, no ka mea e hoʻoliʻiliʻi kēia i ka hopena lubrication. I mea e pale aku ai i ka lepo a ʻaʻahu paha i nā ʻōpala mai ke komo ʻana i ka ʻāpana kūpikipiki e like me ka hiki, a e sila i ka wai e kahe ana i ka ʻaoʻao centrifugal force (ʻano outflow), e wehe ʻia ke uka ma ke apo kūpaʻa e pale i ka lepo mai ka hoʻokomo ʻia ʻana i loko. ka ʻāpana kūpikipiki e ka centrifugal force. Ma ka ʻokoʻa, ke kahe ka wai i ka ikaika centrifugal (kahe o loko), e wehe ʻia ke ana ma ke apo e neʻe ana, a he mea kōkua ka centrifugal force e hoʻolei i ka lepo mai ka lua.

ʻO nā uka liʻiliʻi ma ka ʻili o ka hakina he huinahā like, ʻano like, a me nā kinona ʻē aʻe. ʻAʻole pono ka Groove a hohonu a hohonu paha, i ʻole e hoʻonui ʻia ka liu.

3. ʻO ka lubrication puʻe kūpaʻa:

ʻO ka lubrication hydrostatic i kapa ʻia ʻo ia e hoʻolauna pololei i ka wai lubricating pressurized i loko o ka ʻāpana no ka lubrication. Hāʻawi ʻia ka wai hoʻoheheʻe i hoʻolauna ʻia e kahi kumuwai wai ʻokoʻa, e like me ka pauma uila. Me kēia kaomi lubricating kaomi, ua kūʻē ʻia ke kaomi wai i ka mīkini. Kāhea ʻia kēia palapala i ka sila hydrostatic pressure seal.

Pono e hana i nā ana e hoʻokumu i ka lubrication kiʻi ʻoniʻoni no ka sila mechanical o ka medium kinoea, e like me ka ʻae ʻana i ke kaomi kūmole i kāohi ʻia i ke kiʻina mechanical a i ʻole ka lubrication paʻa, ʻo ia hoʻi, e hoʻohana ana i nā mea lubricating ponoʻī e like me ke komo ʻana i ke komo lima a i ʻole ke apo static. I ka wā e ʻae ai nā kūlana, pono e hoʻololi i ke ʻano o ke kinoea i loko o ke kūlana waena wai e like me ka hiki, kahi maʻalahi no ka lubrication a me ke sila.
