ʻO Sinotruk KC1560030012 336/371HP pahu hoʻoponopono ʻenekini Sinotruk Howo ʻāpana ʻenekini liner cylinder, piston a me nā apo piston pahu mīkini.

ʻIke pili

Hoʻopili pololei ka hoʻonohonoho ʻana o kēia mau ʻāpana ʻehā i ka pāʻani piha o ka hana ʻenekini, a me ke ola lawelawe a me ka hilinaʻi o ka mīkini.ʻEhā hoʻohālikelike he hui kūpono i hoʻokumu ʻia ma o ke koho ʻana, ʻaʻole ia e mālama wale i ka pilikia o ke kūʻai ʻana i nā ʻāpana like ʻole, akā hoʻopau pū kekahi i nā kumu kūpono ʻole ma muli o ke koho ʻana o nā ʻāpana like ʻole, hiki ke hōʻemi nui i ka ulia pōpilikia o ka mīkini a hoʻonui i ka mana. o ka enekini, i mea e hooloihi ai i ke ola lawelawe.Ua aloha ʻia a makemake ʻia e ka hapa nui o nā mea hoʻohana ma ka mākeke ma hope o ke kūʻai aku.

ʻO nā kūlana hana o ka piston he paʻakikī loa.Hoʻopili ka luna me ke kinoea wela kiʻekiʻe a kau i ka hopena kiʻekiʻe kiʻekiʻe a me ka ikaika inertial i hoʻokumu ʻia e ka wikiwiki reciprocating motion.Hoʻopili ʻia nā ʻāpana āpau o ka piston holoʻokoʻa i ka ikaika piha a me ka torque o ka ʻāʻī, ka hoʻopiʻi a me ke kuʻi ʻana, a ʻaʻole kūlike ka hoʻomehana.No laila, koi ʻia ka piston e loaʻa ka liʻiliʻi liʻiliʻi, ka hoʻonui ʻana i ka wela liʻiliʻi, ka hoʻoili wela maikaʻi a me ke kūpaʻa ʻana.ʻO ka piston i hana ʻia e mākou he alumini alumini, ʻo ia ka mea i koho ʻia no ka piston kaʻa i kēia manawa.Pono ka piston e pili pono me ka paia cylinder.ʻO ka hoʻokomo ʻana i ke apo piston ma ka piston ke ana i hana ʻia e hoʻoponopono i kēia pilikia.Hoʻokaʻawale ʻia ke apo piston i ke apo kinoea a me ke apo ʻaila.ʻO ka mea mua ke pale aku i ka hui ʻana mai ke kahe ʻana i loko o ka pahu crankcase;Hana ʻia ka mea hope i ka hao hoʻoheheʻe ʻia, me ka waha inclined a me ka elasticity.Ke hoʻopaʻa lima ʻia ma ka piston, loaʻa iā ia nā hiʻohiʻona o ka hohola i waho a pili i ka paia cylinder.No laila, hana ʻia kā mākou piston apo i ka alumini alumini e hōʻoia i kona elasticity.ʻAʻole pono e lawa ka ikaika mechanical a me ka wela ka mea o ka cylinder liner, akā loaʻa nō hoʻi ke kūpaʻa maikaʻi, ka pale ʻana i ka corrosion, ka paʻa ʻana o ka aila a me ka lubricity, ʻo ia ka mea nui loa ka pale ʻana.I kēia manawa, ʻo nā mea maʻamau i hoʻohana ʻia o ka cylinder liner he nodular cast iron, high phosphorus cast iron and alloy cast iron.ʻO ka mea maʻamau o ka piston pin he kila kalapona haʻahaʻa a i ʻole ke kila kalapona haʻahaʻa.Hoʻohana mau ʻia nā kila 15, 20, 15Cr, 20Cr a me 20Mn2 i nā ʻenekini me ka haʻahaʻa haʻahaʻa.ʻO nā kila kila kila kiʻekiʻe, e like me crni3a, 18cr mnti2 a me 20si MnVB, hoʻohana ʻia no nā ʻenekini hoʻoikaika.I kekahi manawa hiki ke hoʻohana ʻia he 45 kila kalapona.I mea e paʻakikī a paʻakikī ka papa o waho o ka pine piston, pono ka lāʻau wela.E hoʻomoe a kinai i ka ʻili o waho o ka pine piston i hana ʻia me ke kila kalapona haʻahaʻa.E like me ka nui o ka piston pin, ʻo ka hohonu o ka papa carburized ma ke ʻano he 0.5-2mm.No ka 45 kila piston pine, hoʻokō ʻia ka hoʻopau ʻana i ka ʻili, a ʻo ka hohonu o ka papa quenching he 1-1.5mm.
