Njira zosamalira pampu ya injini ya dizilo yojambulira mafuta

(5) Yang'anani chilolezo cha camshaft nthawi zonse
Chilolezo cha axial cha camshaft cha pampu ya jekeseni yamafuta ndizovuta kwambiri, nthawi zambiri pakati pa 0.03 ndi 0.15mm. Ngati chilolezocho ndi chachikulu kwambiri, zotsatira za magawo otumizira odzigudubuza pazitsulo zogwirira ntchito zidzakulirakulira, motero zimawonjezera kuvala koyambirira kwa cam pamwamba ndikusintha njira yoperekera Mafuta; Kutulutsa kochulukirapo kwa axial ndi ma radial kwa mayendedwe a camshaft kungapangitse camshaft kuyenda mosakhazikika, ndodo yosinthira kuchuluka kwa mafuta kunjenjemera, komanso kuchuluka kwamafuta kumasintha nthawi ndi nthawi, kupangitsa injini ya dizilo kusakhazikika. Choncho, m'pofunika kufufuza nthawi zonse ndi Kusintha. Pamene chilolezo cha axial cha camshaft ndi chachikulu kwambiri, chingasinthidwe powonjezera shims kumbali zonse; pamene chilolezo cha radial ndi chachikulu kwambiri, nthawi zambiri chimakhala chofunikira kuti chisinthe ndi china chatsopano.

(6) Yang'anani nthawi zonse momwe kusindikizira kwa msonkhano wa valve wotulutsa mafuta pamakina
Pambuyo popopera jekeseni wamafuta kwa nthawi yayitali, chigamulo chokhwima chikhoza kupangidwa pa kuvala kwa plunger ndi momwe ntchito ya pampu yamafuta imagwirira ntchito poyang'ana momwe kusindikizira kwa valavu yotulutsira mafuta, komwe kumapindulitsa kudziwa. njira zokonzera ndi kukonza. Poyang'anira, masulani maunyolo a mapaipi amafuta othamanga kwambiri pa silinda iliyonse, ndikupopera mafuta ndi pampu yamafuta pamanja ya pampu yoperekera mafuta. Ngati pali mafuta otuluka m'magulu a mapaipi amafuta pamwamba pa mpope wa jekeseni wa mafuta, zikutanthauza kuti valavu yotulutsira mafuta sichimasindikizidwa bwino (zowonadi, idzawonongekanso pamene kasupe wa valve wotuluka mafuta wathyoka. zochitika). Ngati ma silinda angapo sanasindikizidwe bwino, pampu yojambulira mafuta iyenera kusamalidwa bwino ndi kusamalidwa bwino, ndipo mbali zake zonse ziyenera kusinthidwa.
