Ntchito yomanga makina zosefera mpweya
Ntchito yamakina opangira makina ojambulira mpweya ndikusefa zonyansa mumafuta, kuchepetsa kukana kwamafuta, kuonetsetsa kuti mafuta amafuta, ndikuchepetsa kuvala kwazinthu panthawi yogwira ntchito.
Ntchito ya zinthu zosefera mafuta ndikusefa bwino zonyansa monga fumbi, fumbi lachitsulo, ma oxide achitsulo, ndi matope mumafuta amafuta, kuteteza dongosolo lamafuta kuti lisatseke, kuwongolera kuyatsa bwino, ndikuwonetsetsa kuti injini ikuyenda bwino; Chosefera chimakhala munjira yolowera injini, ndipo ntchito yake yayikulu ndikusefa mpweya womwe umalowa mu silinda, potero kuchepetsa kuvala koyambirira kwa silinda, pisitoni, mphete ya piston, valavu, ndi mpando wa valve, kuteteza utsi wakuda. , ndikuwongolera magwiridwe antchito a injini. Kutulutsa mphamvu kumatsimikizika.
Zotsatira za kafukufuku zikuwonetsa kuti zovuta zovala za injini zimaphatikizanso mitundu itatu yosiyana: kuvala kowononga, kuvala kolumikizana ndi kuvala kwa abrasive, ndipo kuvala kwa abrasive kumawerengera 60% -70% ya mtengo wovala. Zosefera zamakina omanga nthawi zambiri zimagwira ntchito m'malo ovuta kwambiri. Ngati sitipanga chinthu chosefera chabwino choteteza chidziwitso, silinda ndi pisitoni mphete ya injini imakula ndikutha mwachangu. Ntchito yayikulu ya "ma cores atatu" ndikuchepetsa kuwonongeka kwa ma abrasives ku injini mwa kukonza bwino kusefera kwa mpweya, mafuta ndi mafuta, ndikuwonetsetsa kuti kasamalidwe ka injini zamagalimoto akuyenda bwino.
Nthawi zambiri, fyuluta yamafuta a injini imasinthidwa maola 50 aliwonse, ndiye maola 300 aliwonse akugwira ntchito, ndipo fyuluta yamafuta imasinthidwa maola 100 aliwonse, kenako maola 300, kutengera mtundu wamafuta odzaza ndi mafuta chifukwa cha kusiyana kwamafuta, wopanga amalimbikitsa moyenerera kukulitsa kapena kufupikitsa kuzungulira kwa m'malo mwa fyuluta ya mpweya. Kuzungulira kosinthira kwa fyuluta ya mpweya yomwe imagwiritsidwa ntchito ndi mitundu yosiyanasiyana imasiyana malinga ndi momwe mpweya umagwirira ntchito. Kuzungulira kosinthira kwa fyuluta ya mpweya kudzasinthidwa momwe kuli koyenera. Sinthani zosefera zamkati ndi zakunja.
