Lesale la piston.
Lesale la piston le sebedisetswa ho kenya mokoti wa piston ka hare ho lesale la tshepe, lesale la piston le arotsoe ka mefuta e mmedi: lesale la kgatello le lesale la oli. Lesale la kgatello le ka sebedisetswa ho kwala kgase ya motswako e ka tukang ka phapusing ya ho tuka; Lesale la oli le sebedisetswa ho hula oli e ngata ho tswa silindareng. Lesale la piston ke mofuta wa lesale la tshepe le nang le phetoho e kgolo ya katoloso ya kantle, e kopantsweng profil le mokoti wa yona o tsamaellanang. Mehele ya piston e kgutlisanang le e potolohang e itshetlehile ka phapang ya kgatello ya kgase kapa mokelikeli ho etsa tiiso pakeng tsa selikalikoe se ka ntle sa lesale le silindara le lehlakore le leng la lesale le mokoti wa lesale.
Sebaka sa ts'ebeliso
Masale a piston a sebelisoa haholo mechineng e fapaneng ea motlakase, joalo ka lienjene tsa mouoane, lienjene tsa diesel, lienjene tsa peterole, li-compressor, mechine ea hydraulic, jj., a sebelisoa haholo likoloing, litereneng, likepeng, likepeng tsa likepe le tse ling. Ka kakaretso, lesale la piston le kentsoe ka har'a lesale la piston, 'me lona le piston, liner ea silindara, hlooho ea silindara le likarolo tse ling tsa kamore li tla sebetsa.
Lesale la piston ke karolo ea bohlokoa ka hare ho enjene ea mafura, eona le silindara, piston, lebota la silindara hammoho ho phethela tiiso ea khase ea mafura. Lienjene tsa likoloi tse sebelisoang hangata li na le mefuta e 'meli ea lienjene tsa disele le peterole, ka lebaka la ts'ebetso ea tsona e fapaneng ea mafura, ts'ebeliso ea masale a piston ha e tšoane, masale a piston a pele a thehoa ka ho betsa, empa ka tsoelo-pele ea theknoloji, masale a piston a tšepe a matla a phahameng a hlahile, 'me ka ts'ebetso ea enjene, litlhoko tsa tikoloho li ntse li ntlafala, mefuta e fapaneng ea lits'ebetso tse tsoetseng pele tsa kalafo ea bokaholimo, joalo ka ho fafatsa ka mocheso, ho betla ka motlakase, ho betla ka chrome, jj. Ho betla ka khase, ho betla ka 'mele, ho koahela bokaholimo, kalafo ea zinc manganese phosphating, jj., ho ntlafatsa haholo ts'ebetso ea lesale la piston.
Mosebetsi oa lesale la piston o kenyelletsa ho tiisa, ho laola oli (taolo ea oli), ho tsamaisa mocheso (phetisetso ea mocheso), tataiso (tšehetso) mesebetsi e mene. Ho tiisa: ho bolela ho tiisa khase, u se ke ua lumella khase ea kamore ea ho tuka hore e lutle ho ea ka har'a crankcase, ho lutla ha khase ho laoloa bonyane, ho ntlafatsa katleho ea mocheso. Ho lutla ha moea ho ke ke ha fokotsa matla a enjene feela, empa hape ho tla etsa hore oli e senyehe, e leng mosebetsi o ka sehloohong oa lesale la khase; Lokisa oli (taolo ea oli): oli e ngata e tlotsang leboteng la silindara e ea hohloa, 'me lebota la silindara le koahetsoe ka filimi e tšesaane ea oli ho netefatsa ho tlotsa ho tloaelehileng ha silindara le piston le lesale, e leng mosebetsi o ka sehloohong oa lesale la oli. Lienjineng tsa sejoale-joale tse lebelo le phahameng, tlhokomelo e khethehileng e lebisoa karolong ea filimi ea oli ea taolo ea lesale la piston; Ho tsamaisa mocheso: mocheso oa piston o fetisetsoa ho liner ea silindara ka lesale la piston, ke hore, phello ea ho pholisa. Ho ya ka data e tshepahalang, 70 ~ 80% ya mocheso o amohelwang ke karolo e ka hodimo ya piston ya piston e sa phodiswang e hasana ka lesale la piston ho ya leboteng la silindara, mme 30 ~ 40% ya piston e phodisang e hasana ka lesale la piston ho ya leboteng la silindara; Tshehetso: Lesale la piston le boloka piston ka silindara, le thibela ho kopana ka ho toba pakeng tsa piston le lebota la silindara, le netefatsa motsamao o boreleli wa piston, le fokotsa kganyetso ya kgohlano, mme le thibela piston ho kgorometsa silindara. Ka kakaretso, piston ya enjene ya peterole e sebedisa masale a mabedi a kgase le lesale le le leng la oli, ha enjene ya disele hangata e sebedisa masale a mabedi a oli le lesale le le leng la khase.
