Ntchito ya chinthu chosefera mafuta a galimoto
Chosefera mafuta, chomwe chimadziwikanso kuti chotsukira mafuta. Chimagwiritsidwa ntchito kuchotsa zinthu zodetsa monga fumbi, tinthu tachitsulo, mpweya woipa ndi tinthu ta soya kuchokera ku mafuta a injini, kuteteza injini.
Zosefera zamafuta zitha kugawidwa m'magulu amitundu yonse yoyendera mafuta ndi yodutsa mafuta. Chosefera chamafuta chimalumikizidwa motsatizana pakati pa pampu yamafuta ndi njira yayikulu yamafuta, motero chimatha kusefa mafuta onse olowetsa mafuta omwe amalowa mu njira yayikulu yamafuta. Chotsukira chosinthira mafuta chimalumikizidwa motsatizana ndi njira yayikulu yamafuta ndipo chimasefa gawo limodzi la mafuta odzola omwe amatumizidwa ndi pampu yamafuta.
Pa nthawi yogwira ntchito ya injini, zitsulo, fumbi, carbon deposits zomwe zimasungunuka kutentha kwambiri, zinthu zonga gel, madzi ndi zinthu zina zimasakanizidwa nthawi zonse mu mafuta opaka mafuta. Ntchito ya fyuluta ya mafuta ndikusefa zonyansa ndi chingamu izi, kusunga mafuta opaka mafuta kukhala oyera ndikuwonjezera moyo wake wautumiki. Fyuluta ya mafuta iyenera kukhala ndi mphamvu yosefera yamphamvu, kukana kuyenda bwino komanso moyo wautali wautumiki. Mu dongosolo lopaka mafuta, mafyuluta angapo okhala ndi mphamvu zosiyanasiyana zosefera amayikidwa - chotsukira, fyuluta yosalala ndi fyuluta yosalala - zomwe zimalumikizidwa motsatizana kapena motsatizana mu njira yayikulu yamafuta. Imodzi yolumikizidwa motsatizana ndi njira yayikulu yamafuta imatchedwa fyuluta yosalala, yomwe mafuta onse opaka mafuta amasefedwa panthawi yogwira ntchito ya injini; yomwe yolumikizidwa motsatizana nayo imatchedwa fyuluta yosalala. Pakati pawo, fyuluta yosalala imalumikizidwa motsatizana mu njira yayikulu yamafuta ndipo ndi yamtundu wamtundu wathunthu wamafuta. Fyuluta yosalala imalumikizidwa motsatizana mu njira yayikulu yamafuta ndipo ndi yamtundu wamtundu wamtundu wagawo. Mainjini amakono agalimoto nthawi zambiri amakhala ndi chotsukira ndi fyuluta yamafuta yosalala. Fyuluta yopyapyala imachotsa zonyansa zokhala ndi kukula kwa tinthu tating'onoting'ono ta 0.05mm kapena kuposerapo kuchokera mu mafuta a injini, pomwe fyuluta yopyapyala imagwiritsidwa ntchito kuchotsa zonyansa zokhala ndi kukula kwa tinthu tating'onoting'ono ta 0.001mm kapena kuposerapo.
Ntchito yaikulu ya chinthu chosefera mafuta a galimoto ndikusefa zinyalala mu mafuta a injini ndikuteteza makina opaka mafuta a injini. Mfundo yake yogwirira ntchito imachitika makamaka kudzera mu kusefera mapepala osefera ndi njira zodutsa ma valve.
Ntchito yosefera
Chosefera cha mafuta chimateteza zinyalala monga tinthu tachitsulo, fumbi ndi mpweya woipa mu mafuta a injini kudzera m'mapepala ambiri osefera (monga pepala losefera lokhala ndi mipope yaying'ono), zomwe zimawaletsa kulowa mkati mwa injini ndikupangitsa kuti awonongeke.
Njira yodutsa valavu
Pamene chinthu chosefera chatsekedwa ndi zinthu zosafunikira, zomwe zimapangitsa kuti mafuta azipanikizika kwambiri, valavu yolowera mkati imatseguka yokha, zomwe zimathandiza kuti mafuta a injini osasefedwa abwerere mwachindunji ku injini, motero kupewa kulephera kwa mafuta chifukwa cha mafuta osakwanira. Komabe, panthawiyi, mafuta a injini amatha kunyamula zinthu zosefedwa, zomwe zimapangitsa kuti mafutawo awonongeke.
Kugawa ndi Kupanga
Chosefera cha mafuta oyenda bwino: Cholumikizidwa motsatizana pakati pa pampu yamafuta ndi njira yayikulu yamafuta, chimasefa mafuta onse a injini.
Chosefera chogawanika: Cholumikizidwa motsatira njira yayikulu yamafuta, chimasefa gawo limodzi la mafuta a injini.
Kulephera kugwira ntchito bwino kwa chinthu chosefera mafuta cha galimoto kungayambitse mavuto monga kuchepa kwa kuthamanga kwa mafuta, phokoso la injini losazolowereka, komanso mphamvu yofooka. Ndikofunikira kuyang'ana ndikuyikanso nthawi yake.
Zochitika zachizolowezi zolakwika
Kutsika kwa kuthamanga kwa mafuta: Chosefera chomwe chatsekeka kapena chowonongeka chingayambitse mafuta osakwanira kuchokera ku pampu yamafuta, zomwe zimayambitsa alamu ya kuwala kwamafuta.
Phokoso losazolowereka la injini: Mafuta osakwanira angayambitse kuwonongeka kosazolowereka kwa zinthu monga crankshaft ndi zipolopolo zolumikizira ndodo, zomwe zimapangitsa kuti pakhale phokoso lachitsulo.
Mphamvu yofooka: Kuchepa kwa mafuta kumapangitsa kuti mphamvu ya injini ichepe, zomwe zimaonekera ngati kuyendetsa mofooka kapena kusuntha giya movutikira.
Chifukwa cha vuto
Kutsekeka: Kuchuluka kwa zinyalala kapena kukalamba kwa pepala losefera kumapangitsa kuti mafuta atsekedwe.
Mavuto okhazikitsa: Kukalamba kwa mphete yotsekera, ulusi wosagwirizana kapena mphamvu yolimba kwambiri kungayambitse kutayikira kwa mafuta kapena kuwonongeka kwa chipolopolo.
Kusankha mafuta a injini molakwika: Kusagwirizana kwa kukhuthala kapena mafuta a injini otsika kumawonjezera kutsekeka kwa chinthu chosefera.
Yankho
Kuyeretsa kapena kusintha: Nthawi zonse sinthani chinthu chosefera (chomwe chimalimbikitsidwa pa mtunda wa makilomita 5,000 mpaka 10,000 aliwonse) ndikutsuka zonyansa zomwe zili mu poto yamafuta.
Yang'anani momwe kutsekera kumagwirira ntchito: Sinthani mphete yotsekera yakale ndikuwonetsetsa kuti mphamvu yoyikira ikukwaniritsa muyezo.
Kufananiza mafuta a injini: Sankhani mtundu woyenera wa mafuta a injini malinga ndi buku la malangizo a galimoto.
njira yodzitetezera
Pewani kuyamba ndi kuyimitsa mtunda waufupi pafupipafupi kuti muchepetse mphamvu ya kuyamba kozizira pa chinthu chosefera.
Gwiritsani ntchito zinthu zoyambirira za fakitale kapena zovomerezeka kuti mupewe kusefa koyipa kwa zinthu zabodza.
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.
