Kutaya kwamafuta nthawi zambiri kumachitika pakugwira ntchito kwa turbocharger

Zifukwa za kutayika kwa mafuta zimafotokozedwa motere:

Pakadali pano, ma turbocharger amitundu yosiyanasiyana ya dizilo nthawi zambiri amakhala ndi mawonekedwe oyandama oyandama. Pamene shaft ya rotor imayenda mothamanga kwambiri, mafuta odzola omwe ali ndi mphamvu ya 250 mpaka 400MPa amadzaza mipata iyi, kuchititsa kuti choyandamacho chizizungulira mofanana ndi nthiti ya rotor pansi pa zigawo zamkati ndi zakunja za filimu yamafuta, koma liwiro lake. ndi yotsika kwambiri kuposa ya rotor shaft. . Chifukwa cha mapangidwe a filimu yamafuta awiri osanjikiza, ndikosavuta kuyambitsa kutayikira kwamafuta mu turbocharger, kufulumizitsa kuvala pakati pa mayendedwe, ma rotor shafts, ndi ma casings, zomwe zimapangitsa kuwonongeka kwa turbocharger ndikuchepetsa magwiridwe antchito a injini ya dizilo.

1. Kusindikiza mphete kuvala ndi kulephera

Chifukwa ndizovuta kusunga mafuta opaka mafuta ndi mpweya wolowa mu turbocharger kukhala zoyera, komanso kutulutsa kwa turbo shaft ndikokulirapo, kumapangitsa kuti mphete yosindikizira ndi ring groove iwonongeke kwambiri, ndipo kusindikiza kudzatayika. Kuphatikiza apo, mafuta opaka mafuta olephera amapangitsa kuti mphete yosindikizirayo iwonongeke pang'onopang'ono ntchito yake yosindikiza mpweya komanso yosindikiza mafuta, zomwe zimapangitsa kuti mafuta azituluka.

2. Kuyika kosayenera kapena kuwonongeka

Pali mphete ziwiri zosindikizira zomwe zimayikidwa muzolowera kumapeto kwa compressor ndi turbo impeller end. Ngati kutseguka kwa mphete ziwiri zoyandikana sikunagwedezeke ndi 180 ° wina ndi mzake panthawi ya msonkhano, zidzachititsa kuti mafuta azituluka mu turbocharger. Mphete yosindikizira ya turbocharger imakhazikika pabokosi ndi mphamvu zotanuka. Mphamvu zotanuka zikachepa, shaft ya turbocharger imasunthira mmbuyo ndi mtsogolo, kusintha kusiyana kwapakati pakati pa mphete yosindikizira ndi nsonga ya annular pa shaft yoyendetsa, zomwe zimapangitsa kuti nkhope ya mphete ikhale yovala, zomwe zimapangitsa kuti mafuta a turbocharger atayike.

3. Mphamvu yolowera ndiyokwera kwambiri

Nthawi zambiri, kukakamiza kolowera kwamafuta opaka turbocharger nthawi zambiri kumakhala 250-400kPa. Kuthamanga kwa mafuta olowera kukakhala kopitilira 600kPa, kupanikizika kwakukulu kumapangitsa kuti mafuta opaka mafuta atuluke kuchokera pachida chosindikizira mpaka kumapeto kwa turbo.

SHOUYUAN, monga katswiriwopanga turbochargerku China, katundu wathu ndi oyenera magalimoto osiyanasiyana. Timapangamapangidwe apamwambaturbocharger, katiriji, mawilo a turbine, mawilo a kompresa,ndi zida zokonzerakwa zaka zambiri. Tadzipereka kupereka makasitomala athu zinthu zapamwamba komanso ntchito yabwino kwambiri.
