5 mau hōʻailona o ka haʻihaʻi turbocharger

Ua ʻōlelo pinepine ʻia ua make ka pahu turbocharger a ʻaʻole puhi. ʻO kēia ʻōlelo ʻakaʻaka o ka mechanics ʻaʻole ia e hoʻolilo i nā mea nona nā kaʻa kahi i hāʻule ai ka turbocharger - ʻo ka hoʻololi ʻana i ka turbine maʻamau e hōʻemi i ka ʻeke ma kahi mau tausani. Eia naʻe, maʻalahi ka ʻike ʻana i nā hemahema o kēia mea. E ʻike i ke kumu ʻaʻole ʻo ia i pahū ma mua o kona make ʻana!

He aha kāu e aʻo ai mai kēia pou?

• Pehea e ʻike ai inā ʻaʻole hana pono ka turbocharger?

I ka pōkole

Hana ka turbocharger i nā kūlana paʻakikī. Ma kekahi ʻaoʻao, ua hoʻouka nui ʻia - ua wili kona rotor a hiki i 250 mau kipi. rpm. Ma ka ʻaoʻao ʻē aʻe, pono ia e hoʻopaʻa i nā wela nui - ʻo nā kinoea hoʻopau e hele i loko ona e wela a hiki i nā haneli degere Celsius. ʻOiai ua hana ʻia nā turbines me nā mea paʻa a hoʻolālā ʻia e hoʻomau i ke ola o nā ʻenekini, he mea maʻamau ka hāʻule ʻole o ka ʻenekini.

Eia nō naʻe, ʻoi aku ka maikaʻi ma mua o nā hōʻailona ʻike: he hāʻule i ka mana mīkini, ka uahi polū a ʻeleʻele paha mai ka paipu hoʻopau, hoʻonui ʻia ka ʻai ʻana i ka ʻaila a me nā leo ʻokoʻa (nā hōkū, uwē, ka walaʻau metala).

1. Hoemi i ka mana

ʻO ka hōʻailona koʻikoʻi o ka hāʻule ʻana o ka pahu compressor ʻo ia ka hāʻule ʻana o ka mana mīkini. E ʻike maoli ʻoe i kēia manawa - e manaʻo ʻoe ua nalowale ke kaʻa i ka wikiwikia e kahaha auanei oe i ka hamau koke. ʻO ka nalo mau ʻana o ka mana ke kumu pinepine ʻia e nā leaks ma waena o ka turbocharger a me ka intake a i ʻole ka ʻōnaehana exhaust, a me ke komo ʻana i kēia mea.

Aia kekahi hōʻailona e hōʻike ana ua hewa ka turbo hana ripple, i.e. hāʻule manawa i ka mana engine. Hoʻokomo pinepine ʻia lākou me ka hoʻokomo ʻana i kahi hōʻailona hewa ma ka dashboard. Ke pili nei kēia pilikia nā mīkini hoʻololi geometry... Hoʻokumu ʻia kēia ma muli o ka hoʻopaʻa ʻia ʻana o nā lau rotor neʻe, no ka laʻana, ma muli o nā waihona i hōʻiliʻili ʻia ma waena o lākou.

2. Uahi polū

ʻO ke kala o ka uahi e hele mai ana mai ka paipu hoʻopau e haʻi nui iā ʻoe e pili ana i ke kūlana o ka turbocharger. Inā he uliuli a, eia kekahi, ua hele pū ʻia me kahi ʻala wela ʻole, a laila Leaka ʻana o ka ʻaila ʻenekini i loko o ke keʻena puhi.... Hiki iā ia ke haʻalele i ka ʻōnaehana lubrication ma nā ʻano like ʻole (no ka laʻana, ma o nā apo piston pōʻino a i ʻole nā ​​sila valve). Ma ke kumumanaʻo, ʻaʻole hiki ke kahe i nā ʻāpana o ka turbine. Noho ʻia i loko o kahi keʻena i pale ʻia e nā sila metala, ʻaʻole like me nā puʻupuʻu lāʻau, ʻaʻole koʻikoʻi a haki ʻia. Eia kekahi, aia ka nui o ke kaomi i loko o ka hale turbocharger - ʻo ia ka mea e hoʻomau ai i ka hana, a ʻo ia ka mea e ʻae ʻole ai i ka ʻaila e kahe i waho o ke keʻena.

Pono e ʻike ʻia ke kumu o nā leaks ʻaʻole i loko o ka turbocharger ponoʻī e like me ka turbocharger ponoʻī. i ka hemahema o ka ʻōnaehana lubrication... ʻO ka pilikia he pahu DPF a i ʻole EGR lepo, nā laina i hoʻopaʻa ʻia e lawe ai i ka aila ma loko o ke keʻena turbine, a i ʻole ka aila nui i loko o ka mīkini.

E nānā i ka holo ʻana o ka ʻenekini!

ʻOiai he mea liʻiliʻi nā kumu, hiki i ka hana liʻiliʻi o nā kaʻa me kahi ʻāpana diesel e pau i kahi haki nui - ka mea i kapa ʻia ʻo ka wikiwiki engine. Hele mai ia ia i ka wā no laila ka nui o ka ʻaila ʻenekini i komo i loko o nā pahu pahu a lilo ia i mea hou o ka wahie. Hoʻomaka ka mīkini e hoʻomaka - hele i nā wikiwiki kiʻekiʻe a kiʻekiʻe, kahi e hoʻonui ai i ka turbocharging. Hāʻawi ka turbine i nā kumu o ka ea i loko o ke keʻena hoʻopau, a me lākou pū kekahi o ... aila, e hoʻonui ai i ka wikiwiki. ʻAʻole hiki ke pani ʻia kēia spiral. Oi aku pinepine ʻaʻole kōkua ka hoʻopau ʻana i ke ahi – Hoʻopau pinepine ʻia nā ʻenekini diesel ma ka ʻoki ʻana i ka lako wahie. A i ka wā e lilo ai kēlā wahie i ʻaila ʻenekini...

ʻO ka hāʻule ʻole o ke kaʻa i ka hapa nui o nā hihia e hopena i ka hemahema o ka ʻāpana hoʻokele.

Hiki iā ʻoe ke heluhelu hou aʻe e pili ana i ka hoʻopuehu ʻenekini ma ʻaneʻi: He maʻi maʻi diesel pupule ʻo Engine scatter. He aha ia a no ke aha ʻaʻole ʻoe makemake e ʻike iā ia?

3. Ka makewai i ka aila a me ke kahe.

Hiki i nā kaʻa supercharged "lawe" i kahi ʻaila hou aʻe - he kūlohelohe kēia. Eia nō naʻe, inā koi pinepine ʻia ka hoʻopiha piha ʻana ma mua o ka mea maʻamau, e nānā pono a loaʻa i kahi mīkini hilinaʻi e nānā i ka ʻōnaehana lubrication. ʻO ka turbine paha ka mea hewa. ʻO kēlā me kēia ʻāpana o ka ʻaila ma nā laina pono e hopohopo. ʻO ka turbocharger lubricated a i ʻole intercooler—ka radiator e hoʻohaʻahaʻa i ka mahana o ka lewa ma mua o ke komo ʻana i ka cylinder—ʻo ia ka hōʻailona hope loa o kahi pilikia ʻenekini koʻikoʻi.

4. Uahi ʻeleʻele

I nā kaʻa turbocharged, i kekahi manawa ke kū ʻē aʻe - a hiki i nā cylinders ʻaʻole lawa ka ea no ka puhi wahie kūpono. Hōʻike ʻia kēia e ka uahi ʻeleʻele a me ka hāʻule o ka mana mīkini. ʻO ka pilikia maʻamau maʻemaʻe mechanical - hiki mai ma muli o ka pōʻino i ka rotor.

5. Kani

Noho mālie nā ʻōnaehana turbocharging o kēia manawa a ʻike wale nā ​​mea hoʻokele iā lākou ke hoʻomaka lākou e hāʻule a no laila e holo nui ai. ʻO nā walaʻau ʻē aʻe i hana koke ʻia e ka ʻenekini ke kumu e hopohopo ai, akā aia kekahi mau leo puana, uwo a i ʻole ke kani ʻana o ka metala e hamo ana i ka metala - maʻamau no ka turbine hāʻule... Hōʻike lākou i ka wā e hoʻokani ʻia ai ka ʻenekini i ka rpm kiʻekiʻe (mai kahi o 1500 rpm) a hoʻonui ʻia me ka hoʻonui ʻana i ka ukana. Hiki ke kumu mai ka liki ʻana o ka paipu a me ka lubrication pilikia, nā hale nahae a me nā bearings ʻeleʻele, i kahi DPF i hoʻopaʻa ʻia a i ʻole catalytic converter.

Pehea e pale aku ai i ka hemahema turbocharger koʻikoʻi? E mālama pono i ka lubrication. Loaʻa iā mākou kahi ʻike no ka mālama ʻana i kāu turbo i kahi kūlana maikaʻi - mai kā mākou blog e aʻo ai ʻoe pehea e hana ai ka turbocharger a pehea e hoʻokele ai i kahi kaʻa turbocharged i ʻole e hoʻonui i ka ʻōnaehana a ma kā mākou hale kūʻai kaʻa .com e ʻike ʻoe i ka ʻaila ʻaila maikaʻi loa. E nānā - e holo mālie ka turbine i kāu kaʻa!
