Basa uye rudzi rwemhete yemafuta
2020-12-02
Basa remhete yemafuta nderekugovera zvakaenzana mafuta ekuzora achiputika pamadziro ecylinder apo piston inokwira kumusoro, iyo inobatsira pakuzora kwepiston, piston ring uye cylinder wall; piston painodzika pasi, inokwenya mafuta ekuzora akawandisa pamadziro ecylinder kudzivirira mafuta Kupwanya mukamuri rinopisa kuti upise. Zvinoenderana neyakasiyana chimiro, iyo mhete yemafuta yakakamurwa kuva marudzi maviri: yakajairika mhete yemafuta uye yakasanganiswa mhete yemafuta.
Ordinary mafuta mhete
Chimiro chemhete yeoiri yakajairwa kazhinji inogadzirwa nealloy cast iron. Gorofu inochekwa pakati pekunze kwedenderedzwa, uye maburi akawanda emafuta ekudonhedza kana slits anogadzirwa pazasi pegoro.
Yakasanganiswa mhete yemafuta
Iyo mhete yemafuta yakasanganiswa inoumbwa nepamusoro uye yakaderera scrapers uye yepakati lining spring. Iyo scrapers yakagadzirwa ne chrome-plated simbi. Munzvimbo yakasununguka, iyo dhayamita yekunze ye scraper yakaiswa pachitubu chemukati yakakura zvishoma kupfuura cylinder diameter. Nharaunda pakati pemashizha zvakare yakakura zvishoma kudarika upamhi hwemhete groove. Kana iyo mhete yemafuta yakasanganiswa uye piston zvaiswa mucylinder, liner chitubu chinomanikidzwa mune ese axial uye radial nzira. Pasi pekuita kwechitubu chesimba re liner spring, wiper inogona kusimbiswa. Kudzvanya kumadziro cylinder kunonatsiridza mafuta ekukwenya maitiro. Panguva imwecheteyo, iwo maviri scrapers zvakare akasimba abut pane ring groove. Iyo mhete yemafuta yakasanganiswa haina backlash, nekudaro ichidzikisa mafuta ekupomba mhedzisiro yepiston mhete. Rudzi urwu rwemhete yemafuta ine kudzvanywa kwepamusoro, kuchinjika kumadziro ecylinder, hombe yekudzoka kwemafuta, huremu hudiki, uye zviri pachena kukwesha mafuta. Naizvozvo, iyo yakasanganiswa mhete yemafuta inoshandiswa zvakanyanya mumainjini ekumhanya. Kazhinji, zvindori zviviri zvemafuta zvinoiswa papiston. Kana zvindori zviviri zvemafuta zvichishandiswa, iyo yakaderera inowanzoiswa pamucheto wezasi wepiston siketi.
