Kodi ntchito ya automobile crankshaft oil seal ndi chiyani
Ntchito yayikulu ya crankshaft oil seal ndikusindikiza crankcase ndikuletsa kutulutsa mafuta. Chisindikizo chamafuta a Crankshaft ndiye chinthu chofunikira kwambiri chosindikizira pagulu la injini, kusamata bwino kumapangitsa kuti mafuta amafuta azitsika, zomwe zimakhudza magwiridwe antchito a injini.
Chisindikizo chamafuta a crankshaft chimazindikira ntchito yake posindikiza mwamphamvu komanso kusindikiza pamitsempha. Kusindikiza kwamphamvu kumatheka ndi kukhudzana pakati pa milomo yosindikiza ndi pamwamba pa shaft yozungulira, yomwe ndi ntchito yofunika kwambiri ya chisindikizo cha mafuta; Chisindikizo chapabowo chimazindikirika poyika m'mphepete mwakunja kwa chisindikizo chamafuta pabowo.
Filimu yamafuta a hydrodynamic imapangidwa pakati pa milomo ya chisindikizo chamafuta ndi mawonekedwe a shaft. filimu yamafuta iyi sangangogwira ntchito yosindikiza, komanso imagwira ntchito yopaka mafuta.
Zida zosindikizira mafuta a Crankshaft nthawi zambiri zimaphatikizapo mphira wa nitrile, mphira wa fluorine, mphira wa silikoni, mphira wa acrylic, polyurethane ndi polytetrafluoroethylene. Posankha zinthu zosindikizira zamafuta, ndikofunikira kulingalira momwe zimayenderana ndi sing'anga yogwirira ntchito, kusinthasintha kwa kutentha komwe kumagwirira ntchito komanso kuthekera kwa milomo kutsatira shaft yozungulira pa liwiro lalikulu .
Kuphatikiza apo, kukhazikitsa ndi kukonza chisindikizo chamafuta a crankshaft ndikofunikira kwambiri. Mukayika, ndikofunikira kuthira mafuta pa mphete yosindikizira ndikuwonetsetsa kuti chisindikizo chamafuta a skeleton ndi perpendicular to axis kupewa kutayikira kwamafuta ndi kuvala kwa chisindikizo chamafuta.
Ngati chisindikizo chamafuta chikapezeka kuti chikukalamba kapena chikutuluka mafuta, chimayenera kusinthidwa munthawi yake kuti injiniyo igwire bwino ntchito ndikuwonjezera moyo wautumiki.
automobile crankshaft oil seal ndi mtundu wa chipangizo chosindikizira chomwe chimayikidwa pa crankshaft ya injini, chomwe chimagwiritsidwa ntchito makamaka kuletsa mafuta opaka mafuta kuti asatayike kuchokera ku crankshaft kupita ku chilengedwe. Zisindikizo zamafuta a Crankshaft nthawi zambiri zimakhala kutsogolo kapena kumbuyo kwa injini, kutengera kapangidwe kagalimoto ndi mtundu wa injini.
Ntchito ya crankshaft oil seal
Ntchito yayikulu ya crankshaft oil seal ndikusunga mafuta opaka mafuta mu injini kuti asatayike komanso kuteteza zonyansa zakunja kulowa mu injini. Imangiriridwa mwamphamvu pamwamba pa crankshaft kudzera mumilomo yake yofewa, kupanga chisindikizo chogwira ntchito ndikuletsa kutayikira kwamafuta. Kuphatikiza apo, chisindikizo chamafuta a crankshaft chingalepheretse kutayikira kwamafuta ndikuwonetsetsa kuti injini ikugwira ntchito bwino.
Zida ndi kapangidwe ka crankshaft oil seal
Chisindikizo chamafuta a crankshaft nthawi zambiri chimapangidwa ndi mphira, zitsulo ndi zinthu zina, zokhala ndi kukana kuvala, kukana kutentha kwambiri, kukana kwamafuta ndi zinthu zina, kuti athe kuthana ndi kusinthasintha kothamanga komanso kusintha kwa magwiridwe antchito a injini. Kapangidwe kake ka milomo yofewa kumatha kulumikizidwa mwamphamvu pamwamba pa crankshaft, kupanga chisindikizo chothandiza.
Malingaliro osinthira ndi kukonza
Chifukwa chisindikizo chamafuta a crankshaft chimakhala ndi gawo lalikulu mu injini, kuwonongeka kwake kapena kulephera kwake kungayambitse kutayikira kwamafuta, komwe kumakhudza momwe injiniyo imagwirira ntchito. Chifukwa chake, kuyang'anira nthawi zonse ndikusintha zisindikizo zamafuta a crankshaft ndi gawo la kukonza injini. Chisindikizo chamafuta chikapezeka kuti ndichokalamba kapena chikutuluka mafuta, chikuyenera kusinthidwa munthawi yake kuti chitsimikizire kudalirika komanso kulimba kwa injini.
Ngati mukufuna kudziwa zambiri, pitilizani kuwerenga zolemba zina patsamba lino!
Chonde tiyimbireni ngati mukufuna zinthu zotere.
Malingaliro a kampani Zhuo Meng Shanghai Auto Co., Ltd. adadzipereka kugulitsa zida zamagalimoto za MG&750 zolandilidwa kugula.
