Mafutawo amaikidwa pansi pa injini, yomwe imadziwikanso kuti crankcase yotsika. Tsopano, gawo lapamwamba la cylinder block ndi cylinder block, kuphatikizapo gawo la pansi la mafuta ndi crankcase. Cylinder block ndi crankcase ziyenera kulumikizidwa pamodzi.
Tsopano kuti zikhale zosavuta kupanga ndi kukonza, gawo lapamwamba la crankshaft ndi silinda zimaphatikizidwa, ndipo poto yamafuta imakhala gawo losiyana, lolumikizidwa ku crankcase ndi zomangira.
Chidebe cha mafuta chimagwiritsidwa ntchito kusungiramo mafuta, komanso, ntchito zina, monga kutseka chidebe cha mafuta kuti chikhale malo abwino ogwirira ntchito, kusunga dothi, kuyeretsa kutentha mu mafuta odzola, ndi zina zotero.
Malo oyikapo chidebe cha mafuta Ntchito ya chidebe cha mafuta
Ntchito yaikulu ya poto yamafuta ndi kusunga mafuta. Injini ikasiya kugwira ntchito, gawo lina la mafuta mu injini limabwerera ku poto yamafuta ndi mphamvu yokoka. Injini ikayamba, pampu yamafuta imatenga mafutawo kupita ku ziwalo zonse zodzoladzola za injini, ndipo mafuta ambiri nthawi zambiri amakhala mu poto yamafuta. Kawirikawiri, ntchito ya poto yamafuta ndikutseka crankcase ngati chipolopolo cha thanki yosungiramo zinthu, kutseka crankcase, kupewa zinyalala kulowa mu thanki, kusonkhanitsa ndikusunga mafuta odzola chifukwa cha pamwamba pa kukangana, kutulutsa kutentha pang'ono, kupewa kusungunuka kwa mafuta odzola.
Kugawa chipolopolo cha mafuta pansi
madzi onyowa
Magalimoto ambiri pamsika ndi onyowa mafuta, motero amatchedwa poto wonyowa mafuta, chifukwa cha crankshaft ya injini crankshaft ndi link head, crankshaft idzamizidwa mu mafuta odzola mafuta kamodzi, imasewera gawo la mafuta. Nthawi yomweyo, chifukwa cha kuthamanga kwa crankshaft, crank iliyonse yothamanga kwambiri yomwe imamizidwa mu thanki yamafuta, idzayambitsa duwa lamafuta ndi mafuta enaake kuti idzole mafuta a crankshaft ndi shaft tile, iyi ndi yomwe imatchedwa mafuta opopera. Izi zimafuna kutalika kwa madzi kwa mafuta odzola mu poto yamafuta. Ngati ili yotsika kwambiri, crankshaft crankshaft ndi connecting rod big head sizingamizidwa mu mafuta odzola, zomwe zimapangitsa kuti crankshaft, connecting rod ndi shaft tile zisakhale zosalala. Ngati mafuta odzola ali okwera kwambiri, amayambitsa kumiza konse kwa bearing, kuwonjezera kukana kozungulira kwa crankshaft, ndipo pamapeto pake kuchepetsa magwiridwe antchito a injini. Nthawi yomweyo, mafuta odzola ndi osavuta kulowa mchipinda choyaka cha silinda, zomwe zingayambitse kuyaka kwa injini, spark plug carbon ndi mavuto ena.
Njira yothira mafuta iyi ndi yosavuta, palibe chifukwa chokhazikitsa thanki ina yamafuta, koma momwe galimotoyo imayendera siyenera kukhala yayikulu kwambiri, apo ayi ingayambitse ngozi yophwanya mafuta otayikira, kuyaka matailosi ndi kukoka silinda. Kapangidwe kake ka mafuta pansi pa chipolopolocho kamanyowa.
madzi ouma
Ma sump owuma amafuta amagwiritsidwa ntchito m'mainjini ambiri othamanga. Sisunga mafuta mu poto yamafuta, kapena, palibe poto yamafuta. Malo osunthawa omwe ali mu crankcase amathiridwa mafuta pokanikiza m'mabowo oyezera. Chifukwa injini ya poto yamafuta yowuma imachotsa ntchito yosungira mafuta mu poto yamafuta, motero kutalika kwa poto yamafuta osakonzedwa kumachepa kwambiri, ndipo kutalika kwa injini kumachepanso. Ubwino wa pakati pa mphamvu yokoka ndi wabwino powongolera. Ubwino waukulu ndikupewa vuto la poto yamafuta yonyowa yosiyanasiyana yomwe imachitika chifukwa choyendetsa mwamphamvu.
Mafuta ambiri omwe ali mu poto yamafuta amafunika kuumitsidwa, osati ambiri kapena ochepa. Ngati sali odzaza, ayenera kutayidwa. Monga magazi a anthu, mafuta omwe ali mu poto yamafuta amasefedwa kudzera mu pampu yamafuta kupita ku fyuluta, kenako kupita kumaso komwe kumafunika mafuta, ndipo pamapeto pake kupita ku poto yamafuta kuti agwiritsidwe ntchito nthawi ina. Moyo wamafuta a injini nawonso umafunika, ndipo uyenera kusinthidwa nthawi ikakwana. Mafuta ambiri amapangidwa ndi chitsulo chopyapyala. Chotsukira mafuta chokhazikika chimayikidwa mkati kuti chipewe kugwedezeka koyenera ndi kupopera komwe kumachitika chifukwa cha kugwedezeka kwa makina amafuta, komwe kumathandiza kuti mafuta odzola asalowe. Cholamulira chamafuta chimayikidwa m'mbali kuti chiwone kuchuluka kwa mafuta. Kuphatikiza apo, gawo la pansi la poto yapansi lili ndi pulagi yamafuta yosinthira mafuta.
Muyenera kusamala ndi poto yamafuta mukayendetsa, chifukwa poto yamafuta imakhala pansi pa injini. Ngakhale kuti mbale yapansi pa injini imatetezedwa, ndiyonso yosavuta kukanda poto yamafuta zomwe zimapangitsa kuti mafuta atuluke. Musachite mantha ngati poto yamafuta ituluka. Onani nkhani iyi patsamba lino yokhudza momwe —— imakhudzira kutayikira kwa poto yamafuta.
