Chifukwa Chachikulu Chowonongeka kwa Turbocharger
2021-07-26
Zolephera zambiri za turbocharger zimachitika chifukwa chogwiritsa ntchito molakwika ndikukonza njira. Magalimoto amagwira ntchito m'malo osiyanasiyana komanso nyengo, ndipo malo ogwirira ntchito a turbocharger ndi osiyana kwambiri. Ngati sichikugwiritsidwa ntchito ndikusamalidwa bwino, ndizosavuta kuwononga turbocharger yosiyidwa.
1. Kusakwanira kwa mphamvu yamafuta ndi kuthamanga kwa kuthamanga kunapangitsa kuti turbocharger iyake nthawi yomweyo. Injini ya dizilo ikangoyambika, imagwira ntchito mothamanga kwambiri komanso kuthamanga kwambiri, zomwe zimapangitsa kuti mafuta azikhala osakwanira, zomwe zimapangitsa: ① kusakwanira kwamafuta amtundu wa turbocharger ndi thrust bear; ②pa magazini ya rotor ndi kunyamula Pali mafuta osakwanira kuti magazini ikhale yoyandama; ③Mafuta samaperekedwa ku ma fani mu nthawi yomwe turbocharger ikugwira ntchito kale pa liwiro lachilendo. Chifukwa cha mafuta osakwanira pakati pa awiriawiri osuntha, pamene turbocharger imazungulira pa liwiro lalikulu, mayendedwe a turbocharger amawotcha ngakhale kwa masekondi angapo.
2. Kuwonongeka kwamafuta a injini kumapangitsa kuti mafuta azikhala ochepa. Kusankhidwa kosayenera kwamafuta a injini, kusakaniza mafuta a injini zosiyanasiyana, kutayikira kwamadzi ozizira mu dziwe lamafuta a injini, kulephera kusintha mafuta a injini munthawi yake, kuwonongeka kwa cholekanitsa mafuta ndi gasi, ndi zina zotere, kungayambitse mafuta a injini kuti awonongeke ndikuwonongeka. kupanga madipoziti sludge. Dothi lamafuta limaponyedwa pakhoma lamkati la chipolopolo cha riyakitala pamodzi ndi kasinthasintha wa turbine ya kompresa. Zikachulukana pamlingo wina, zimakhudza kwambiri kubwerera kwamafuta kwa khosi lonyamula la turbine kumapeto. Kuphatikiza apo, matopewo amawotchedwa mu gelatinous yolimba kwambiri chifukwa cha kutentha kwambiri kuchokera ku gasi wotulutsa. Pambuyo pochotsa gelatinous flakes, ma abrasives amapangidwa, zomwe zimapangitsa kuti pakhale ma turbine end bearings ndi magazini.
3. Zinyalala zakunja zimalowetsedwa munjira yolowera kapena kutulutsa mpweya wa injini ya dizilo kuti iwononge chopondera. • Liwiro la ma turbine ndi ma compressor impellers a turbocharger amatha kufikira kupitilira kwa 100,000 pamphindi. Zinthu zakunja zikalowa mu injini ya dizilo komanso kutulutsa mpweya, mvula yamkuntho imawononga choponderacho. Zinyalala zing'onozing'ono zidzasokoneza choyimitsa ndikusintha kalozera wa mpweya wa tsamba; zinyalala zazikulu zidzapangitsa kuti tsamba la choyikapo liphwasuke kapena kusweka. Nthawi zambiri, bola zinthu zakunja zikalowa mu kompresa, kuwonongeka kwa gudumu la kompresa kumakhala kofanana ndi kuwonongeka kwa turbocharger yonse. Chifukwa chake, posamalira turbocharger, chosefera cha fyuluta ya mpweya chiyenera kusinthidwa nthawi yomweyo, apo ayi, pepala lachitsulo muzitsulo zosefera lingathenso kugwa ndikuwononga turbocharger yatsopano.
4. Mafuta ndi onyansa kwambiri ndipo zinyalala zimalowa mu dongosolo lopaka mafuta. Ngati mafuta agwiritsidwa ntchito kwa nthawi yayitali, chitsulo chochuluka, silt ndi zonyansa zina zidzasakanizidwa mmenemo. Nthawi zina chifukwa cha kutsekedwa kwa fyuluta, khalidwe la fyuluta silili bwino, ndi zina zotero, mafuta onse onyansa sangadutse mu fyuluta yamafuta. Komabe, imalowa munjira yamafuta molunjika kudzera pa valavu yodutsa ndikukafika pamwamba pa zoyandama zoyandama, zomwe zimapangitsa kuti ziwombankhanga ziwonongeke. Ngati particles zonyansa ndi zazikulu kwambiri kuti zitseke mkati mwa njira ya turbocharger, turbo booster idzapangitsa kuvala kwa makina chifukwa cha kusowa kwa mafuta. Chifukwa cha liwiro lapamwamba kwambiri la turbocharger, mafuta omwe ali ndi zonyansa adzawononga mayendedwe a turbocharger kwambiri.
