He aha ka hoʻohana ʻana i kahi liner turbocharger kaʻa
ʻO ka hana nui o ka turbocharger automotive ka hoʻonui ʻana i ka lawe ʻana o ka mīkini, ma laila e hoʻonui ai i ka mana puka a me ka torque o ka mīkini, i loaʻa ai i ke kaʻa ka mana hou . Ma keʻano kikoʻī, hoʻohana ka turbocharger i ka ikehu kinoea hoʻopau mai ka mīkini e hoʻokele i ka compressor, a hoʻopaʻa i ka ea i loko o ka paipu intake, e hoʻonui ai i ka nui o ka intake, e hiki ai i ka mīkini ke puhi i ka wahie hou aʻe, e hoʻonui ai i ka mana .
Pehea ka hana ʻana o ka turbocharger
ʻO ka Turbocharger ka mea nui i ʻelua ʻāpana: turbine a me ka compressor. Ke hana nei ka ʻenekini, hoʻokuʻu ʻia ke kinoea hoʻopau ma o ka paipu hoʻopau, e hoʻokuke ana i ka turbine e milo. ʻO ka hoʻololi ʻana o ka turbine e hoʻoneʻe i ka compressor a hoʻopaʻa i ka ea i loko o ka paipu intake, ma laila e hoʻonui ai i ke kaomi intake a me ka hoʻomaikaʻi ʻana i ka pono o ka puhi ʻana a me ka mana.
ʻO nā pono a me nā pōʻino o nā turbochargers
Pōmaikaʻi:
Hoʻonui i ka mana : Hiki i nā Turbocharger ke hoʻonui i ka lawe ʻana i ka ea, e ʻae i ka mīkini e hana hou i ka mana a me ka torque no ka neʻe like ʻana.
ʻOi aku ka maikaʻi o ka hoʻokele waiwai : ʻOi aku ka maikaʻi o nā ʻenekini me ka turbocharged, e mālama maʻamau i ka 3%-5% o ka wahie, a he hilinaʻi kiʻekiʻe, nā hiʻohiʻona kūpono maikaʻi a me ka pane transient .
hoʻololi i ke kiʻekiʻe kiʻekiʻe : hiki i ka turbocharger ke hana i ka mīkini e mālama i ka mana kiʻekiʻe ma ke kiʻekiʻe kiʻekiʻe, e hoʻonā i ka pilikia o ka oxygen lahilahi ma ke kiʻekiʻe .
Nā hemahema:
Turbine hysteresis : ma muli o ka inertia o ka turbine a me ka halihali waena, i ka wā e piʻi koke ai ke kinoea hoʻopau, ʻaʻole e piʻi koke ka wikiwiki o ka turbine, e hopena i ka mana hysteresis .
ʻAʻole maikaʻi ka hopena haʻahaʻa haʻahaʻa : inā he haʻahaʻa haʻahaʻa a i ʻole kaʻa kaʻa, ʻaʻole maopopo ka hopena o ka turbocharger, ʻoi aku ka maikaʻi ma mua o ka mīkini aspirated kūlohelohe .
Hana ʻia nā turbochargers automotive i nā mea like ʻole e like me nā huila, nā bearings, nā pūpū a me nā impellers. Hana ʻia nā huila me nā mea superalloy, e like me Inconel, Waspaloy, etc., e hoʻokō i nā koi o ke kiʻekiʻe kiʻekiʻe a me ke kaomi .
Hana pinepine ʻia nā bearings i ka cermet a me nā mea ʻē aʻe e hoʻomaikaʻi ai i ka lole a me ke kūpaʻa corrosion .
No ka ʻāpana pūpū, ʻo ka pūpū compressor ka hapa nui o ka alumini alumini a i ʻole ka magnesium alloy e hōʻemi i ke kaumaha a hoʻomaikaʻi i ka pono, ʻoiai ʻo ka turbine shell ka hapa nui o ke kila .
Hoʻohana nui ʻia ka impeller a me ka shaft i ke kila, ʻoi aku ka hoʻohana pinepine ʻana o ka impeller compressor i ka superalloy, nona ke kūpaʻa kiʻekiʻe kiʻekiʻe o ka oxidation, ikaika a me ke kūpaʻa corrosion .
Nā lako o nā ʻāpana like ʻole a me kā lākou hana
huila huila : ka hoʻohana ʻana i nā mea hoʻoheheʻe wela kiʻekiʻe, e like me Inconel, Waspaloy, etc., e hoʻokō i nā koi o ka wela kiʻekiʻe a me ke kaomi .
amo : hoʻohana maʻamau i ka metala seramika a me nā mea ʻē aʻe e hoʻomaikaʻi ai i ka ʻaʻahu a me ka pale ʻana i ka corrosion.
pūpū:
compressor shell : ʻo ka hapa nui o ka alumini alumini a i ʻole ka magnesium alloy, e hōʻemi i ke kaumaha a hoʻomaikaʻi i ka pono .
ʻo ka huila turbine: ʻo ka nui o nā mea kila i hoʻolei ʻia.
impellers a me shafts : ʻo ka hapa nui o ke kila, ʻoi aku ka nui o nā impeller compressor e hoʻohana pinepine i ka superalloy, ʻoi aku ka maikaʻi o kēia alloy i ke kiʻekiʻe kiʻekiʻe o ka oxidation resistance, ikaika a me ka corrosion resistance .
Nā kumu hoʻololi o ke koho mea
ʻO ke koho ʻana i nā mea turbocharger e noʻonoʻo nui i nā kumu aʻe:
ʻO ka wela kiʻekiʻe a me ke kiʻekiʻe kiʻekiʻe : kiʻekiʻe ka wela o loko a me ke kaomi o ka turbocharger, a pono e koho i nā mea me ka wela kiʻekiʻe a me ke kūpaʻa kiʻekiʻe.
ʻaʻahu pale : pono nā ʻāpana koʻikoʻi e loaʻa i kahi pale lole e hoʻomaikaʻi ai i ke ola lawelawe .
mau waiwai : pono nā mea i lawa ka ikaika a me ka paʻakikī e hoʻokō i nā pono o ka hana wikiwiki .
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.
ʻO Zhuo Meng Shanghai Auto Co., Ltd. ua kūpaʻa e kūʻai aku i nā ʻāpana kaʻa MG&750 e kuai.
