Kodi chisindikizo cha mafuta chakutsogolo cha crankshaft ya galimoto ndi chiyani?
Chisindikizo cha mafuta chakutsogolo cha crankshaft ya galimoto ndi chinthu chofunikira kwambiri chotseka injini, chomwe chimagwiritsidwa ntchito makamaka poletsa kutuluka kwa mafuta opaka (mafuta a injini) kuchokera kumapeto kwa crankshaft ndikuletsa fumbi, madzi ndi zinyalala kuti zisalowe mkati mwa injini.
Ntchito zazikulu
Kutseka mafuta a injini: Mukazungulira crankshaft mwachangu, zimaonetsetsa kuti mafuta a injini satuluka m'malo omwe ali pakati pa crankshaft ndi chivundikiro cha injini.
Kupewa fumbi ndi dothi: Kuletsa zinthu zodetsa zakunja kuti zisalowe mkati mwa injini, kuteteza zigawo zofunika monga ma bearing.
Kusunga kukhazikika kwa dongosolo lopaka mafuta: Kuonetsetsa kuti kayendedwe ka mafuta mkati mwa injini kakugwira ntchito bwino komanso kupewa zolakwika zazikulu monga kugwidwa kwa silinda ndi kutentha kwa mabearing chifukwa cha kusowa kwa mafuta.
Ili kumapeto kwa injini, makamaka pakati pa crankshaft ndi chivundikiro cha injini, nthawi zambiri kumbali ya choyendetsera lamba (monga lamba wa nthawi kapena mbali ya lamba wa jenereta).
Kapangidwe ndi Zipangizo
Mitundu yodziwika bwino: Zomatira zamafuta zambiri zimakhala zamtundu wa chimango (monga mtundu wa TC), zomwe zimakhala ndi chimango chachitsulo, mlomo womatira wa rabara, ndi kasupe wodzilimbitsa wokha.
Zipangizo Zodziwika:
Rabala ya Nitrile (NBR)
Mpira wa Fluoro (FKM)
Rabala ya silikoni (VMQ)
Polytetrafluoroethylene (PTFE), ndi zina zotero.
Kukana Kutentha: Nthawi zambiri -40°C mpaka 180°C, yoyenera malo ogwirira ntchito a injini omwe amatentha kwambiri komanso mwachangu.
Kuwonetsa Zolakwa
Madontho a mafuta kapena kutayikira kwa mafuta pamalo opangira injini kapena kutsogolo kwa crankshaft
Kuchuluka kwa mafuta kotsika kwambiri
Fungo loyaka limatha kudziwika mukayambitsa injini yozizira (chifukwa cha mafuta omwe amathira pazigawo zotentha)
Malangizo Osinthira
Mukangozindikira kuti pali kutayikira, kuyenera kusinthidwa mwachangu momwe zingathere kuti kupewe kugwira ntchito kwa nthawi yayitali zomwe zimapangitsa kuti mafuta asakwanire.
Njira yosinthira imafuna kugwiritsa ntchito zida zapadera (monga chokokera mafuta, makina opondereza), ndipo ndikofunikira kuyeretsa pamwamba pa crankshaft, kuyika mafuta okwanira a injini musanayike mafuta atsopano.
Chosindikizira mafuta chakutsogolo cha crankshaft ndi chaching'ono koma ndi "choteteza chosaoneka" chofunikira chomwe chimatsimikizira kuti makina opaka mafuta a injini amagwira ntchito bwino.
Ntchito yaikulu ya chisindikizo cha mafuta chakutsogolo cha galimoto ndikutseka mbali yakutsogolo ya chisindikizo kuti mafuta a injini asatuluke ndikuletsa zinyalala kuti zisalowe.
Kuletsa Kutayikira kwa Mafuta: Chosindikizira mafuta chakutsogolo cha crankshaft chimayikidwa kumapeto kwa crankshaft (nthawi zambiri kumbali ya pulley ya injini), ndipo ntchito yake yayikulu ndikutseka crankshaft yozungulira, kuletsa mafuta a injini kutuluka kuchokera ku crankcase kupita kunja kwa injini, motero kusunga magwiridwe antchito abwinobwino a makina opaka mafuta ndikupewa kuipitsidwa kwa mafuta m'chipinda cha injini.
Kupatula Zigawo Zopaka Mafuta: Zimachotsa crankshaft yopaka mafuta ndi zigawo zina zamkati kuchokera ku zigawo zakunja zotulutsa mafuta (monga pulley) kuti zitsimikizire kuti mafuta opaka mafuta satuluka.
Kuletsa Zinyalala Kulowa: Chotsekera mafuta chingalepheretsenso fumbi, matope, nthunzi ya madzi, ndi zina zotero, kulowa mkati mwa injini, kuteteza mabearing a crankshaft ndi zigawo zina zofunika, komanso kuchepetsa kuwonongeka.
Njira Yokwaniritsira Kutseka: Filimu yopyapyala yamafuta othamanga imapangidwa pakati pa mlomo wa chisindikizo chamafuta ndi pamwamba pa crankshaft yozungulira, yomwe imatha kutseka mafuta a injini ndikuyika mafuta pamwamba pa mlomo ndi shaft, potero imapangitsa kuti kutseka kukhale kogwira mtima.
Zomwe Zimayambitsa Vuto la Crankshaft Front Oil Seal ya Galimoto ndi limodzi mwa mavuto omwe injini ikukumana nawo, makamaka chifukwa cha kutayikira kwa madzi. Ngati sizingathetsedwe pakapita nthawi, zingayambitse mafuta ochepa a injini, kuchepetsa mphamvu, komanso chiopsezo chodziyatsa yokha. Izi ndi mfundo zazikulu zochokera ku deta yaposachedwa yovomerezeka ya anthu onse:
Zomwe Zimayambitsa Vuto Lofala
Mavuto a chisindikizo cha mafuta: Zipangizo za rabara zosagwira ntchito bwino zomwe sizigwira ntchito bwino ndi mafuta, sizigwira ntchito bwino, kapena sizimakalamba bwino, zimatha kusokonekera mosavuta, komanso zimasweka.
Kukhazikitsa kosayenera: Chosindikizira mafuta chimapendekeka, sichili pamalo ake, kapena sichigwiritsa ntchito zida zapadera, zomwe zimapangitsa kuti milomo iwonongeke kapena kusweka kosagwirizana;
Pakuyika, zinthuzo sizimatsukidwa, ndipo zinthu zosafunika zimakanda chisindikizo cha mafuta kapena pamwamba pa crankshaft.
Kuvala kwa Crankshaft: Pamwamba pa khosi la crankshaft pali mikwingwirima, ellipticity, kapena kusinthasintha kwakukulu, zomwe zimawononga kutseka komwe kumayikidwa ndi chosindikizira cha mafuta.
Malo ogwirira ntchito injini molakwika:
Kugwira ntchito kwa nthawi yayitali komanso kutentha kwambiri kumathandizira kukalamba kwa chisindikizo cha mafuta;
Zolakwika mu makina opumira mpweya a crankcase zimapangitsa kuti kupanikizika kwamkati kukhale kwakukulu kwambiri, zomwe zimapangitsa kuti chisindikizo cha mafuta chitsegulidwe.
Kugwiritsa ntchito mafuta a injini molakwika: Kugwiritsa ntchito mafuta a injini omwe si apachiyambi kapena osatchulidwa, zomwe zimapangitsa kuti filimu yopaka mafuta isapangidwe bwino ndikuwonjezera kuwonongeka kwa chisindikizo cha mafuta.
Kukalamba mwachilengedwe: Ndi kuwonjezeka kwa nthawi yogwira ntchito (nthawi zambiri kupitirira zaka 5), rabala imataya kusinthasintha ndipo imapanga ming'alu.
Zizindikiro Zachizolowezi Zolakwika
Madontho a mafuta kapena kutayikira kwa mafuta kumapeto kwa injini (pafupi ndi pulley);
Kugwiritsa ntchito mafuta mwachangu, pomwe kuchuluka kwa mafuta oyeretsera mafuta kumatsika kwambiri;
Kuwala kwa alamu ya kuthamanga kwa mafuta kumayatsa mukayamba (mavuto aakulu);
Mukachotsa poto yamafuta, madontho atsopano amafuta amatha kuoneka pafupi ndi crankshaft.
Mayankho
Sinthani zomatira zamafuta zapamwamba kwambiri: Sankhani zinthu zoyambirira kapena zodalirika, ndikuwonetsetsa kuti zinthuzo ndi kukula kwake zikugwirizana.
Njira zokhazikika zokhazikitsira:
Gwiritsani ntchito chida chosindikizira chokha, kusunga chisindikizo cha mafuta mofanana;
Musanayike, ikani mafuta okwanira osagwiritsa ntchito mafuta (kuti mupewe kutsekeka kwa mafuta);
Tsukani bwino malo oyikapo kuti zinyalala zisalowe.
Yang'anani ndi kukonza crankshaft:
Kuwonongeka pang'ono kumatha kupukutidwa ndi kupukutidwa;
Kuwonongeka kwakukulu kumafuna kusintha crankshaft.
Kufufuza ndi kuthetsa mavuto a injini:
Yang'anani ngati makina opumira mpweya a crankcase sakutsekedwa;
Onetsetsani kuti makina oziziritsira ali bwino kuti injini isatenthe kwambiri;
Gwiritsani ntchito mafuta a injini omwe akugwirizana ndi zomwe wopanga akufuna.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
