ʻO ka ikaika elastic o ke apo piston kahi mea nui e pili ana i ka ʻaila ʻaila o ka paipu hoʻopau. Hiki ke nānā ʻia ka elasticity o ke apo piston me kahi mea hōʻike puna a i ʻole ke ʻano hoʻohālikelike. I kēia manawa, hiki ke kūkulu pū ʻia ke apo piston kahiko a me ke apo piston, a hiki ke hoʻopili ʻia ke kaomi mai luna ma ka lima. Inā hui nā awa apo kahiko a he ʻokoʻa ko nā puka apo hou, ʻo ia hoʻi, ʻaʻohe elasticity o ke apo piston. E nānā i ke ʻano o ka hoʻopili ʻana a me ka sila ʻana o ke apo piston a me ka liner cylinder: E kau i ke apo piston flat i loko o ka liner cylinder, e kau i kahi ʻōpuʻu kukui ma lalo o ke apo piston, a kau i kahi pale kukui ma luna e nānā i ka leaka māmā a me ke degere hoʻopaʻa. ke apo piston ma ka liner cylinder.

ʻO ke koi maʻamau ʻo ia ke ana ʻana i ka leakage māmā o ke apo piston me kahi ana mānoanoa, ʻaʻole pono ia ma mua o 0.03mm. Holoi ke apo piston ma muli o ka haʻalulu i ka wā e hana ai. He mea maʻamau kēia. Ua hoʻokomo ka ʻenekini i kahi liner cylinder hou i ke kau ʻana i ka hui piston connecting rod. ʻOiai ka lōʻihi o ka hoʻokaʻawale ʻia ʻana o nā apo piston ma kahi kihi i kuhikuhi ʻia, ʻaʻole e hoʻohuli ʻia nā puka o nā apo piston e uhi kekahi i kekahi. Ke hoʻopuka ka liner cylinder i ka ellipse a me ka taper ma muli o ka ʻaʻahu hapa a i ʻole ke komo ʻana o ka piston, hiki ke hoʻohuli ʻia nā puka o ke apo piston i ka ʻaoʻao like a hiki i ka ellipse. No ka mea i kēia manawa, ma muli o ka ellipse o ka cylinder liner, ua pale ʻia ka hoʻolōʻihi ʻia o ka puka piston apo mai ka ʻōwili ʻana, e hoʻoneʻe mālie ana nā puka apo, kahe ke kinoea i lalo, a pakele ka ʻaila ʻenekini i luna a hoʻokuʻu ʻia.

I ka wā e wili ʻia ai ke koʻokoʻo hoʻohui, ʻoi aku ka nui o ka wehe ʻana ma waena o ka piston a me ka cylinder set, a ʻoi aku ka nui o ka wehe ʻana o ke apo piston, hiki ke hoʻoheheʻe ʻia ka ea, e hoʻoneʻe ai i ke apo piston e hana i kahi. pālua. EQ6100-1 engine piston apo manawa pani: ma waena o nā overhauls ʻelua o ka ʻenekini, hele ka kaʻa ma kahi o 80,000 km, ʻo ia ka mea like me ka 0.15mm o ka ʻauʻau cone cylinder, a i ʻole ka ʻāpana hope o ke apo piston ma mua o 2mm; ka mana engine Ua emi nui ka hana, e pi'i nui ana ka ho'ohana 'ana i ka wahie a me ka aila lubricating, ua ma'alahi ka pulupulu i ka waiho kalapona, a nahaha ke apo piston. Ke koho ʻana i ke apo piston, pono e hoʻohana ʻia kahi apo piston o ka pae like me ka piston.
