apo piston.
Hoʻohana ʻia ke apo piston e hoʻokomo i ka piston groove i loko o ke apo metala, ua hoʻokaʻawale ʻia ke apo piston i ʻelua ʻano: ke apo kōmike a me ke apo ʻaila. Hiki ke hoʻohana ʻia ke apo hoʻopaʻa e hoʻopaʻa i ke kinoea hui pū ʻia i loko o ke keʻena puhi; Hoʻohana ʻia ke apo ʻaila e ʻohi ai i ka ʻaila nui mai ka cylinder. ʻO ke apo piston kahi ʻano apo elastic metala me ka nui o ka hoʻonui ʻana i waho, i ʻākoakoa ʻia i loko o ka ʻaoʻao a me kāna ʻāpana annular e pili ana. ʻO ka pānaʻi ʻana a me ka hoʻololi ʻana i nā apo piston e hilinaʻi i ka ʻokoʻa o ke kaomi o ke kinoea a i ʻole ka wai e hana ai i sila ma waena o ka pōʻai o waho o ke apo a me ka cylinder a me kekahi ʻaoʻao o ke apo a me ke apo apo.
Ka laulā o ka noi
Hoʻohana nui ʻia nā apo piston i nā ʻano mīkini mana, e like me nā ʻenekini mokuahi, nā mīkini diesel, nā mīkini ʻaila, compressors, hydraulic presses, etc., hoʻohana nui ʻia i nā kaʻa, nā kaʻaahi, nā moku, nā yachts a pēlā aku. ʻO ka maʻamau, hoʻokomo ʻia ke apo piston i loko o ke apo apo o ka piston, a ʻo ia a me ka piston, cylinder liner, cylinder head a me nā mea ʻē aʻe o ke keʻena e hana i ka hana.
ʻO ke apo piston ka mea nui i loko o ka mīkini wahie, ʻo ia a me ka cylinder, piston, cylinder wall e hoʻopau i ke sila o ka wahie kinoea. ʻO nā mīkini kaʻa maʻamau i hoʻohana ʻia he ʻelua mau ʻano o ka diesel a me nā ʻenekini, ma muli o kā lākou hana wahie like ʻole, ʻaʻole like ka hoʻohana ʻana i nā apo piston, ua hoʻokumu ʻia nā apo piston mua ma ka hoʻolei ʻana, akā me ka holomua o ka ʻenehana, ke kila kiʻekiʻe. Ua hānau ʻia nā apo piston, a me ka hana o ka ʻenekini, hoʻomau ka hoʻomaikaʻi ʻana i nā koi o ke kaiapuni, nā ʻano hana lapaʻau kiʻekiʻe kiʻekiʻe, e like me ka thermal spraying, electroplating, chrome plating, etc. Gas nitriding, physical deposition, surface coating, zinc manganese phosphating lapaʻau, etc., hoʻomaikaʻi nui i ka hana o ke apo piston.
ʻO ka hana o ke apo piston e pili ana i ka hoʻopaʻa ʻana, ka hoʻoponopono ʻana i ka ʻaila (ka mana ʻaila), ka lawe ʻana i ka wela (heat transfer), alakaʻi (kākoʻo) ʻehā mau kuleana. Sealing: e pili ana i ka hoʻopaʻa ʻana i ke kinoea, mai hoʻokuʻu i ka leaka o ke keʻena kuni i ka crankcase, hoʻomalu ʻia ka leakage kinoea ma ka liʻiliʻi, hoʻomaikaʻi i ka hana wela. ʻAʻole e hōʻemi wale ka leakage o ka ea i ka mana o ka mīkini, akā e hoʻohaʻahaʻa i ka ʻaila, ʻo ia ka hana nui o ke apo kinoea; Hoʻoponopono i ka aila (ʻaila hoʻomalu): ʻoki ʻia ka ʻaila lubricating keu ma ka paia cylinder, a ua uhi ʻia ka paia cylinder me kahi kiʻi ʻoniʻoni ʻoniʻoni e hōʻoia i ka lubrication maʻamau o ka cylinder a me ka piston a me ke apo, ʻo ia ka hana nui o ka. ke apo aila. I nā ʻenekini kiʻekiʻe kiʻekiʻe o kēia wā, ua uku ʻia ka manaʻo kūikawā i ka hana o ka piston ring control oil film; Ka lawe ʻana i ka wela: lawe ʻia ka wela o ka piston i ka cylinder liner ma o ke apo piston, ʻo ia hoʻi, ka hopena hoʻomaha. Wahi a ka ʻikepili hilinaʻi, 70 ~ 80% o ka wela i loaʻa e ka piston top o ka piston uncooled i hoʻopuehu ʻia ma o ke apo piston i ka paia cylinder, a ʻo 30 ~ 40% o ka piston hoʻoheheʻe ʻia e hoʻopuehu ʻia ma o ke apo piston i ka cylinder pā; Kākoʻo: Mālama ke apo piston i ka piston i loko o ka cylinder, pale i ka pilina pololei ma waena o ka piston a me ka paia cylinder, e hōʻoia i ka neʻe ʻana o ka piston, e hoʻemi i ka pale ʻana, a pale i ka piston mai ke kīkēkē ʻana i ka cylinder. ʻO ka maʻamau, hoʻohana ka piston o ka ʻenekini ʻaila i ʻelua apo kinoea a me hoʻokahi apo ʻaila, aʻo ka mīkini diesel e hoʻohana maʻamau i ʻelua apo ʻaila a hoʻokahi apo kinoea.
ʻIke maikaʻi a maikaʻi ʻole
ʻAʻole e loaʻa i ka ʻili hana o ke apo piston nā nicks, scratches, peeling, ka cylinder o waho a me nā ʻaoʻao o luna a me lalo o ka hopena paʻa, ʻaʻole i ʻoi aku ka nui o ka curvature deviation ma mua o 0.02-0.04 mm, ka subsidence maʻamau o ka. ʻAʻole iʻoi aku ka nui o ke apo i ka 0.15-0.25 mm, a me ka elasticity a me ka hoʻomaʻemaʻe o ke apo piston e hoʻokō i nā koi. Eia kekahi, pono mākou e nānā i ka leakage māmā o ke apo piston, ʻo ia hoʻi, ua pālahalaha ke apo piston i loko o ka cylinder, e kau i kahi kukui liʻiliʻi ma lalo o ke apo piston, e kau i kahi pale kukui ma luna, a laila e nānā i ka leakage māmā ma waena. ke apo piston a me ka paia cylinder, e hōʻike ana inā maikaʻi ka pilina ma waena o ke apo piston a me ka paia cylinder. Ma lalo o nā kūlana maʻamau, ʻaʻole pono e ʻoi aku ka liʻiliʻi o ka leak leak o ke apo piston i ana ʻia me kahi ana mānoanoa ma mua o 0.03 mm. ʻAʻole pono e ʻoi aku ka lōʻihi o ka leakage leakage māmā ma mua o 1/3 o ke anawaena cylinder, ʻaʻole pono e ʻoi aku ka lōʻihi o kekahi mau leakage leakage māmā ma mua o 1/3 o ke anawaena cylinder, a ʻo ka lōʻihi o ka nui o kahi helu. ʻAʻole pono ka leakage māmā ma mua o 1/2 o ke anawaena cylinder, i ʻole, pono e hoʻololi ʻia. Hōʻike ke apo piston e kaha ana i ka GB/T 1149.1-94 e kaha ʻia nā apo piston a pau e pono ai ke kau ʻana ma ka ʻaoʻao luna, ʻo ia hoʻi, ka ʻaoʻao kokoke i ke keʻena kuni. ʻO nā apo i kaha ʻia ma ka ʻaoʻao kiʻekiʻe: ke apo cone, chamfer i loko, ke apo papa ʻoki ʻoki waho, ke apo ihu, ke apo wedge a me ke apo aila e koi ana i ke kuhikuhi ʻana, a ua kaha ʻia ka ʻaoʻao o luna o ke apo.
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 iā mākou inā makemake ʻoe i ia mau huahana.
