Kodi chopangira mafuta pampu ndi chiyani?
Kuphatikizika kwa pampu yamafuta ndiye gawo lalikulu mu injini lomwe limayang'anira kupereka mafuta a injini. Lili ndi nyumba, chivundikiro chakumapeto, shaft yoyendetsera pampu yamafuta, seti ya giya ndi valavu yochepetsera kupanikizika, ndi zina zotero. Mfundo yake yogwirira ntchito ndi yakuti shaft yoyendetsera imayendetsa seti ya giya kuti izungulire, kukoka mafuta a injini kuchokera mu poto yamafuta ndikuyikankhira kumalo osiyanasiyana opaka mafuta a injini kuti zitsimikizire kuti makina opaka mafuta akugwira ntchito bwino.
Ntchito yaikulu
Chopangira mafuta pampu chimasunga kukhazikika kwa mphamvu ya injini kudzera mu ntchito yopopera mafuta, kuteteza kuwonongeka kwa zigawo kapena kutentha kwambiri chifukwa cha kupanikizika kosakwanira kwa mafuta. Ntchito yake imakhala ndi magawo awiri: kuyamwa mafuta ndi kupanikizika kwa mafuta.
Gawo loyamwa mafuta la Youdaoplaceholder0: Shaft yoyendetsera imazungulira giya, ndikupanga mphamvu ya centrifugal kuti itenge mafuta a injini kuchokera mu poto yamafuta kupita ku chipinda chopopera.
Gawo la Youdaoplaceholder0 Kupanikizika kwa mafuta: Giya limakankhira mafuta a injini kenako limadutsa munjira yamafuta kupita kumalo aliwonse opaka mafuta a injini.
Zigawo zazikulu
Youdaoplaceholder0 Nyumba ndi chivundikiro chakumapeto : kupereka chithandizo cha kapangidwe kake ndikuletsa kutayikira kwa mafuta;
Youdaoplaceholder0 Seti ya shaft ndi giya yoyendetsera : Ntchito yopopera mafuta imachitika kudzera mu kutumiza kwa ma meshing;
Youdaoplaceholder0 Valavu yoletsa kupanikizika : Imalamulira kupanikizika kwa mafuta kuti kusapitirire mtengo womwe wakhazikitsidwa ndikuteteza chitetezo cha dongosolo.
Kuphatikizika kwa pampu yamafuta ndiye gawo lalikulu la makina opaka mafuta a injini. Ntchito yake yayikulu ndikunyamula mafuta a injini kuchokera mu poto yamafuta kupita ku zigawo zokangana za injini kudzera mu kupanikizika, kuonetsetsa kuti mafuta opaka, kuziziritsa ndi kuyeretsa zikugwira ntchito bwino.
Youdaoplaceholder0 Core function
Mafuta ozungulira mpweya wa Youdaoplaceholder0: Pampu yamafuta imagonjetsa kukana kwa dera lamafuta kudzera mu supercharging yamakina (kupanikizika nthawi zambiri kumakhala 150-600 kpa), kulola mafuta a injini kusuntha kuchokera mu poto yamafuta kudzera mu fyuluta kupita kuzinthu zoyenda mwachangu monga crankshaft ndi piston, ndikupanga filimu yamafuta kuti achepetse kukangana.
Youdaoplaceholder0 Chithandizo choziziritsa ndi kuyeretsa : Mafuta a injini ozungulira amachotsa kutentha komwe kumachitika chifukwa cha kukangana ndikusefa zinyalala monga zitsulo zodulidwa kudzera mu fyuluta, ndikusunga ukhondo wa makina opaka mafuta.
Youdaoplaceholder0 Zowonjezera
Youdaoplaceholder0 Chitetezo choletsa kupanikizika : Valavu yolumikizira yoletsa kupanikizika (valavu yochepetsera kupanikizika) imatulutsa kupanikizika pamene kupanikizika kwa mafuta kuli kwakukulu kwambiri kuti payipi isawonongeke.
Youdaoplaceholder0 Kusungira mafuta : Mapangidwe ena amatha kusunga mafuta kwakanthawi kuti akwaniritse zosowa zamafuta kwakanthawi kochepa.
Kulephera kwa kusonkhana kwa pampu ya mafuta nthawi zambiri kumaonekera ngati zizindikiro monga kuyamba kovuta, kuthamanga kofooka, phokoso losazolowereka komanso kugwedezeka. Zizindikiro zenizeni zimagwirizana kwambiri ndi chomwe chachititsa kulephera.
Zizindikiro zodziwika bwino
Youdaoplaceholder0 Zovuta kuyambitsa : Zimafunika kuyatsa kangapo kuti ziyambe, limodzi ndi phokoso la "putt-putt", lomwe nthawi zambiri limayamba chifukwa cha kupanikizika kosakwanira kwa mafuta kuchokera ku pampu yamafuta (kupanikizika kwabwinobwino kwamafuta 2.5-3.5MPa).
Youdaoplaceholder0 Kuthamanga kofooka : Kugwedezeka kumachitika pamene galimoto ikuthamanga mwadzidzidzi, ndipo mphamvu ya galimotoyo imachepa kwambiri, makamaka ikakwera mapiri kapena ikanyamula katundu wolemera.
Phokoso losazolowereka: Phokoso lopitirira "kugwedezeka" pa thanki yamafuta, lomveka bwino pa liwiro lopanda ntchito, lingayambitsidwe ndi kuwonongeka kwa mabearing kapena kusintha kwa impeller.
Youdaoplaceholder0 Kugwiritsa ntchito mafuta molakwika : Kugwiritsa ntchito mafuta kumawonjezeka mwadzidzidzi ndi malita 1-2 pa makilomita 100. Pambuyo pochotsa zinthu monga kuthamanga kwa matayala, ndikofunikira kuyang'ana kwambiri pakuwona momwe pampu yamafuta imatsekerera.
Nyali ya fault yayatsidwa: ECU imazindikira mafuta osakhala bwino ndipo imayambitsa nyali yochenjeza.
Chifukwa cha vuto
Youdaoplaceholder0 Kuwonongeka kwa makina : Kukalamba ndi kusweka kwa diaphragm mkati mwa pampu yamafuta kumapangitsa kuti mphamvu yoperekera mafuta ichepe (yomwe imawoneka kawirikawiri pambuyo pa makilomita 60,000).
Kutseka kwa fyuluta ya Youdaoplaceholder0 : Zodetsa zomwe zimatseka fyuluta zimakakamiza pampu yamafuta kugwira ntchito mopitirira muyeso, zomwe zimapangitsa kuti iwonongeke mwachangu.
Youdaoplaceholder0 Kuthamanga kwa mafuta kosazolowereka : Ngati kuthamanga kwa mafuta kuli kotsika kuposa 1.8MPa, kukonza ndikofunikira; apo ayi, kungayambitse kuwonongeka kwa injini.
Cholakwika cha Youdaoplaceholder0 solenoid valve : Kuchuluka kwa okosijeni kwa ma relay contacts kungayambitse ma short circuits kapena ma open circuits, zomwe zimapangitsa kuti mafuta asamayende bwino.
Kuyankha mwadzidzidzi
Dinani pang'onopang'ono poyikirapo pompo ya mafuta kuti muyese ngati ikugwira ntchito
Gwiritsani ntchito chida chodziwira vuto la OBD kuti muwerenge khodi yolakwika
Yang'anani kuchuluka kwa kuthamanga kwa mafuta (kuyenera kufika pa 3.0MPa mkati mwa masekondi atatu mutayamba kugwiritsa ntchito)
Sinthani valavu ya solenoid kapena diaphragm yomwe yawonongeka (zida zoyambirira za fakitale zimafunika)
Ndikoyenera kusintha fyuluta nthawi zonse (makilomita 20,000 aliwonse) ndikuyesa kuthamanga kwa mafuta kuti mupewe kugwiritsa ntchito zowonjezera mafuta zosafunikira.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
Malingaliro a kampani Zhuo Meng Shanghai Auto Co., Ltd. yadzipereka kugulitsa MG&MAXUSzida zamagalimoto zalandiridwa kugula.
