Mafutawo amaikidwa pansi injini, yomwe imadziwikanso kuti ndi yotsika ya cranks. Tsopano, kumtunda kwa cylinder block ndi cylinder block, kuphatikiza gawo lotsika la poto wamafuta ndi crankcase. Cylinder block ndi crankcase iyenera kulumikizidwa.
Tsopano kusanthula kosavuta ndikukonza, kumtunda kwa crankshaft ndi cylinder block amaponyedwa limodzi, ndipo poto wamafuta amakhala gawo linalake, lolumikizidwa ndi zomangira.
Poto yamafuta imagwiritsidwa ntchito kusunga mafuta, ndipo, zoyambira zina, monga kusindikiza cranks kuti ikhale yoyera yopanga mafuta, malo othira mafuta odzola, etc.
Malo okhazikitsa poto wamafuta a poto
Ntchito yayikulu ya poto yamafuta ndi yosungira mafuta. Injiniya ikayima kuthamanga, gawo la mafuta mu injini limabwerera ku poto wamafuta ndi mphamvu yokoka. Mafuta akayamba, pampu yamafuta ikayamba mafuta ku malekezero onse a injini, ndipo mafuta ambiri nthawi zambiri amakhala mu poto yamafuta. Nthawi zambiri, gawo la poto lamafuta ndikusindikiza crankcase ngati chipolopolo cha thanki yosungirako, tsekani mafuta opangira mafuta, pewani kutentha, pewani mafuta othira mafuta ambiri.
Gulu la mafuta pansi
chonyowa sump
Magalimoto ambiri pamsika ndi poto yamafuta, chifukwa chake amatchedwa poto wamafuta, chifukwa cha poto wa injini, chifukwa cha mutu wa nguluweti, amagwira ntchito yopaka mafuta. Nthawi yomweyo, chifukwa chothamanga kwambiri kwa crankshaft, chilichonse chothamanga kwambiri kumitu yamafuta, chidzadzutsa maluwa ena ndi mafuta a mafuta a crankshaft ndi shaft, uwu ndiye wotchedwa wonyezimira. Izi zimafuna kuti madzi odzola mafuta odzola mu poto yamafuta. Ngati chotsika kwambiri, chokoleti cha crankshaft cronk ndi cholumikiza rod mutu sangathe kuthira mafuta odzola, chifukwa chosowa mafuta ndi kusalala kwa crankshaft, shaft. Ngati mafuta opangira mafuta ndi okwera kwambiri, zimayambitsa kumiza kwathunthu, kumawonjezera kukana kwa crankshaft, ndipo pamapeto pake kumachepetsa injini. Nthawi yomweyo, mafuta opangira mafuta ndiosavuta kulowa m'chipinda chophatikiza cha kuyamwa, chomwe chidzatsogolera injini yoyaka, kuweta kaboni kaboni ndi mavuto ena.
Makina opangidwa ndi mafutawa ndi osavuta pakupanga, osafunikira kukhazikitsa thanki ina, koma zomwe zimapangitsa kuti galimoto ikhale ikuluikulu, kapena ichotse ngozi yophwanya mafuta, yoyaka matayala ndikukoka ma cylinder. Donthonsi yamafuta pansi
pukuta dzuwa
Madzi owuma amagwiritsidwa ntchito mumiyala yambiri. Sizisunga mafuta mu poto yamafuta, kapena, palibe poto wamafuta. Izi zimayenda mu crankcase yochimwa pokakamiza kudzera mabowo. Chifukwa injini yowuma yamafuta imachotsa ntchito yosungirako mafuta, kotero kutalika kwa poto wamafuta wosungunuka kwambiri, ndipo kutalika kwa injiniyo kumafupikanso. Phindu la malo ochepetsedwa a mphamvu yokoka ndiyabwino kuti muthe kuwongolera. Ubwino waukulu ndikupewa chodabwitsa cha poto wamafuta wonyowa chifukwa cha kuyendetsa bwino.
Muyenera kupukuta mafuta mu poto yamafuta, osati zambiri osati zambiri. Ngati sichidzakhuta, ziyenera kutayidwa. Monga magazi aanthu, mafuta mu poto yamafuta imasefedwa kudzera mu pufwa yamafuta, kenako kumaso ogwiritsira ntchito mafuta, kenako mpaka ku poto wamafuta chifukwa chotsatira. Moyo wautumiki wa mafuta injini amafunikiranso, ndipo ziyenera kusinthidwa nthawi yake. Poto wa mafuta ambiri amapangidwa ndi malo opyapyala. Mafuta okhazikika amaikidwa mkati kuti apewe kudandaula koyenera ndipo kuwaza komwe kamayambitsidwa ndi madzi osokoneza thupi. Wolamulira wamafuta amaikidwa pambali kuti ayang'ane kuchuluka kwa mafuta. Kuphatikiza apo, pansi pa poto wapansi kumakhala ndi pulagi yamafuta yamafuta.
Muyenera kusamala ndi poto wamafuta mukamayendetsa, chifukwa poto wamafuta ali pansi pa injini. Ngakhale kuti mbale ya injini imatetezedwa, ndiyosavuta kuyika poto wamafuta omwe amatsogolera ku kutaya mafuta. Osadandaula ngati poto wamafuta. Onani nkhani iyi patsamba lino momwe limakhalira - limachita ndi mafuta poto.
