Chiyambi cha Zosefera Mafuta

Pa ntchito injini, zinyalala zitsulo, fumbi, madipoziti mpweya oxidized pa kutentha kwambiri, colloidal zinyalala, ndi madzi mosalekeza kulowa mafuta lubricating. Ntchito ya sefa yamafuta ndikuchotsa zonyansa zamakina ndi zinthu za colloidal, kusunga mafuta opaka mafuta kukhala oyera ndikukulitsa moyo wake wautumiki. Zosefera zamafuta ziyenera kukhala ndi mphamvu zosefera mwamphamvu, kukana kuyenda kochepa, komanso moyo wautali wautumiki. Makina opaka mafuta amagwiritsa ntchito zosefera zingapo za kuthekera kosiyanasiyana-kusonkhanitsa zosefera, zosefera zowoneka bwino, ndi zosefera zabwino-zolumikizidwa motsatana kapena motsatizana mugawo lalikulu lamafuta. (Zosefera zolumikizidwa motsatizana ndi nyumba yayikulu yamafuta zimatchedwa zosefera zonse-zosefera, momwe mafuta onse opaka mafuta amadutsa injini ikugwira ntchito; zosefera zolumikizidwa molumikizana zimatchedwa zosefera zogawanika{7}}zosefera.) Sefa yokhotakhota yolumikizidwa motsatizana ndi nyumba yayikulu yamafuta imakhala-sefa yodzaza; fyuluta yabwino yolumikizidwa molumikizana ndi malo opangira mafuta ndi gawo logawanika-sefa. Ma injini amakono amagalimoto onyamula anthu nthawi zambiri amakhala ndi zosefera ndi zosefera imodzi yokha-yodzaza mafuta. Chosefera chowoneka bwino chimachotsa zonyansa zokhala ndi tinthu tating'ono 0.05mm kapena kupitilira apo mumafuta a injini, pomwe fyuluta yabwino imagwiritsidwa ntchito kuchotsa zonyansa zokhala ndi tinthu tating'ono 0.001mm kapena kupitilira apo.
