He aha nā apo piston
ʻO nā apo piston he mau apo metala i hoʻokomo ʻia i loko o nā ʻauwaha piston. Ma ke ʻano he mau ʻāpana koʻikoʻi o ka ʻenekini, hana nui lākou i nā hana e like me ke sila ʻana, ka hoʻoili wela, a me ka ʻōpala ʻaila. Ua māhele ʻia lākou i ʻelua ʻano: nā apo kinoea a me nā apo ʻaila.
ʻO Youdaoplaceholder0 Ka wehewehena a me ka hana o nā apo piston
ʻO nā apo piston he mau ʻāpana apo hao i hoʻokomo ʻia i loko o nā ʻauwaha piston. ʻO kā lākou mau hana nui:
Hana sila ʻo Youdaoplaceholder0: No ka pale ʻana i ke kinoea kiʻekiʻe i loko o ke keʻena kuni mai ka leaka ʻana i loko o ka crankcase, e hōʻoiaʻiʻo ana i ka hana pono o ka ʻenekini.
Ka hopena hoʻoili wela Youdaoplaceholder0 : ʻO ka wela i omo ʻia e ka piko o ka piston e alakaʻi ʻia i ka paia cylinder a hoʻopuehu ʻia ma o ka ʻōnaehana hoʻoluʻu.
ʻO Youdaoplaceholder0 Ka ʻoki ʻana i ka ʻaila a me ka hoʻolaha ʻana i ka ʻaila : ʻO ke apo ʻaila ke kuleana no ka ʻoki ʻana i ka ʻaila keu ma ka paia o ka cylinder a me ka hana ʻana i kahi ʻili ʻaila like e hōʻemi i ka friction a me ke komo ʻana.
ʻO Youdaoplaceholder0 ʻAno a me ka hoʻokaʻawale ʻana
ʻO ke apo kinoea Youdaoplaceholder0 (apo sila) :
Aia maʻamau ia ma nā ʻauwaha apo mua a me ka lua o ka piston a hoʻopaʻa nui i ke kinoea kuni.
Pono nā mea hana e loaʻa ke kūpaʻa wela kiʻekiʻe a me ka ikaika kiʻekiʻe, e like me ka hao hoʻolei ʻia a i ʻole ka hao ductile.
ʻO ke apo ʻaila Youdaoplaceholder0 :
Aia ma ke awāwa apo ʻekolu, hoʻihoʻi ʻia ka ʻaila mīkini keu ma o ka lua o ka mea ʻoki ʻaila e pale aku ai i ka hanana "puhi ʻaila".
Ka ʻano hana a me nā waiwai o nā mea
Hana nā apo piston ma lalo o nā kūlana friction wela kiʻekiʻe, kaomi kiʻekiʻe a me ka wikiwiki kiʻekiʻe a pono e hoʻokō i nā koi aʻe:
He elasticity maikaʻi kona a hōʻoia i kahi kūpono paʻa me ka paia cylinder.
He kiʻekiʻe kona kūpaʻa ʻana i ka ʻaʻahu e kū ai i ka haʻalulu paheʻe lōʻihi.
He kūpaʻa wela ikaika kona a hiki ke pale i ka deformation a me ka hāʻule ʻana i nā mahana kiʻekiʻe.
ʻO nā hana nui o ke apo piston e pili ana i ka sila ʻana i ke kinoea kuni, ka hoʻomalu ʻana i ka ʻili ʻaila lubricating, ka hoʻokele ʻana i ka wela a me ke kākoʻo ʻana i ka neʻe ʻana o ka piston. He ʻāpana koʻikoʻi ia no ka hana paʻa o nā mīkini kuni kūloko.
ʻO ka hana nui o ke apo piston ʻo ia
ʻO ka hopena sila ʻo Youdaoplaceholder0.
I mea e pale aku ai i ke kinoea wela kiʻekiʻe a me ke kaomi kiʻekiʻe i loko o ke keʻena kuni mai ke komo ʻana i loko o ka pahu crankcase a hōʻoia i ka pono o ke kaomi ʻana a me ka hahau mana (ka hana nui o ke apo kinoea).
E pale i ka ʻaila ʻenekini mai ke komo ʻana i loko o ke keʻena kuni ma o ka hakahaka ma waena o ka piston a me ka cylinder e komo i ka puhi ʻana (hana kōkua apo ʻaila).
ʻO Youdaoplaceholder0 Ka hopena kaohi ʻaila.
ʻO ke apo aila, ma o kahi ʻano i hoʻolālā kūikawā ʻia, e ʻoki ana i ka aila mīkini keu ma ka paia o ka cylinder, e hōʻemi ana i ka hoʻohana ʻana i ka aila a me ke kūkulu ʻia ʻana o nā waihona kalapona.
I ka manawa like, ua hana ʻia kahi ʻili aila like ma ka paia o ka cylinder e hōʻoia i ka hopena lubrication ma waena o ka piston a me ka cylinder.
Ka hopena hoʻoili wela o Youdaoplaceholder0.
Ma kahi o 70% a 80% o ka wela i omo ʻia e ke poʻo piston e alakaʻi ʻia i ka paia cylinder a hoʻokuʻu ʻia ma o ka ʻōnaehana hoʻoluʻu e pale aku i ka piston mai ka wela nui a me ka deforming.
ʻO ka hopena kākoʻo ʻo Youdaoplaceholder0.
E hoʻēmi i ke kū'ē ʻana o ka friction ma waena o ka piston a me ka paia cylinder e mālama i ke kūpaʻa o ka neʻe linear o ka piston.
E pale i ka ʻaʻahu kūpono ʻole i hoʻokumu ʻia e ka pilina pololei ma waena o ka piston a me ka paia cylinder (i ʻike nui ʻia ʻo "knocking").
ʻO ke ʻano hana hoʻokō o ka hana
Hoʻolālā kaulike kaomi Youdaoplaceholder0 : Hoʻokō ʻia ka sila ʻana ma o ka hui pū ʻana o ke kaomi kinoea a me ka ikaika elastic, e mālama ana i ka sila pono ʻoiai inā e ʻaʻahu ʻia.
ʻO ka hui pū ʻana o nā apo he nui ʻo Youdaoplaceholder0: ʻO ke ʻano maʻamau he 2 mau apo kinoea a me 1 apo ʻaila, e kālele ana i ka sila ʻana i ke kinoea a me ka kaohi ʻana i ka ʻili ʻaila.
ʻO Youdaoplaceholder0 ʻenehana mālama ʻili : Hoʻonui i ke kūpaʻa ʻana i ka ʻaʻahu a hoʻolōʻihi i ke ola lawelawe ma o ka hoʻohana ʻana i nā kaʻina hana e like me ka chromium plating a me ka nitriding.
ʻO nā hemahema o ke apo piston e hōʻike nui ʻia e like me ka puhi ʻana o ka ʻaila mīkini (e like me ka uahi polū e puka mai ana mai ka paipu hoʻopau), ka hoʻonui ʻia ʻana o ka hoʻohana ʻana i ka wahie, ka emi ʻana o ka mana a me ka hāʻule ʻana o ka sila cylinder, a pēlā aku. ʻO ke kumu nui o kēia mau hemahema ʻo ia ka pale ʻana i nā waihona kalapona, ka ʻaʻahu ʻana a i ʻole ke kau pono ʻole ʻana. Pono ka ʻike loea a me ka lawelawe manawa kūpono e pale aku i ka pōʻino nui o ka mīkini.
Nā hanana hewa maʻamau
ʻO ka hemahema o ke apo piston e alakaʻi pinepine i nā hōʻailona i ʻike ʻia:
ʻO Youdaoplaceholder0 Ka hanana ʻā ʻana o ka ʻaila : puka mai ka uahi polū mai ka paipu hoʻopau, a piʻi nui ka hoʻohana ʻana i ka ʻaila (no ka laʻana, ʻoi aku ma mua o 0.5 lita no 1,000 kilomita).
ʻO Youdaoplaceholder0 Ka emi ʻana o ka hana : Hoʻonāwaliwali ʻia ka mana o ka ʻenekini, nāwaliwali ka wikiwiki, me ka piʻi ʻana o 30%-50% o ka hoʻohana ʻana i ka wahie.
ʻO Youdaoplaceholder0 ʻAno ʻē o ka mīkini: ʻo ka liki ʻana o ka cylinder ke kumu o ka piʻi ʻana o ka mahana o ka hoʻopau ʻana, ka mahana wai ʻē i loko o ka liner cylinder, a i ʻole ka walaʻau a me ka haʻalulu ʻē.
Ka nānā ʻana i nā kumu nui o
ʻO nā kumu nui o ka hewa e komo pū ana me:
ʻO Youdaoplaceholder0 Ka pale ʻana o ka waihona kalapona : ʻO ka hoʻohana lōʻihi ʻana i ka wahie haʻahaʻa a i ʻole ka hoʻokele pōkole e hiki ke hoʻopili i nā waihona kalapona i loko o nā hakahaka o nā apo piston, e helu ana no 60% a 70% o nā hihia hewa, e ʻae ana i ka ʻaila mīkini e komo i loko o ke keʻena kuni a puhi.
ʻO Youdaoplaceholder0 Ka ʻaʻahu a haki paha o ke apo Piston : ʻO ka mālama pono ʻole ʻana i ka kānana ea e hoʻokomo i ka lepo, e hana ana i ka ʻaʻahu o ke awāwa apo a i ʻole ka haki luhi o ke kino apo, e hōʻemi ana i ka hana sila.
ʻO Youdaoplaceholder0 Ke kīnā o ka hoʻonohonoho ʻana a i ʻole ka hoʻolālā:
Ua liʻiliʻi loa ka hakahaka o ke apo piston, a ua paʻa ia i loko o ka cylinder ma hope o ka hoʻonui ʻia ʻana o ka wela.
ʻO ke kūlou ʻana o ke koʻokoʻo hoʻohui e hoʻohuli ai i ka piston i ka wā o ka hana, e hopena ana i ka ʻaʻahu like ʻole.
ʻO Youdaoplaceholder0 Nā ʻano hana hōʻoia a me ka hoʻāʻo ʻana
Pono kahi hōʻoia i hōʻoia ʻia i ka hui pū ʻana o nā ʻano hana loea:
Youdaoplaceholder0 Nānā mua : E hoʻopaʻa i ka hoʻohana ʻana i ka ʻaila a nānā inā ua puka mai ka uahi polū a i ʻole ke kinoea hoʻopau ʻawaʻawa i ka wā hoʻomaka anu.
ʻIke ʻana i ka mea hana Youdaoplaceholder0:
Nānā endoscopic o nā waihona kalapona ma ka paia cylinder a i ʻole ke komo ʻana o ke apo piston.
E ana i ke kaomi o ka cylinder (ʻo ka maʻamau, pono ia e ʻoi aku ma mua o 10bar). Inā haʻahaʻa ia, hōʻike ia ua hāʻule ka sila.
?Inā makemake ʻoe e ʻike hou aku, e hoʻomau i ka heluhelu ʻana i nā ʻatikala ʻē aʻe ma kēia pūnaewele!
E ʻoluʻolu e kelepona mai iā mākou inā makemake ʻoe i kēlā mau huahana.
ʻO Zhuo Meng Shanghai Auto Co., Ltd. ua kūpaʻa ʻo ia i ke kūʻai aku ʻana iā MG&MAXUShoʻokipa ʻia nā ʻāpana kaʻa e kūʻai.
