thepa e entsoeng ka mochini oa piston

1. 45 # tšepe
Tlas'a maemo a tloaelehileng, haeba mojaro oa molamu oa piston o se o moholo haholo, 45 # tšepe e atisa ho sebelisoa bakeng sa tlhahiso.Kaha 45 # tšepe ke ka tloaelo ho sebelisoa seaplane quenched le bohale tšepe sebopeho tšepe, e na le matla a phahameng le machinability e ntle, haholo-holo ha welded rolara foreime e fetisitse phekolo ea mocheso oa khase, e ka fumana khanyetso e itseng., polasetiki le ho hanyetsa ho roala, kahoo ke e 'ngoe ea lisebelisoa tse sebelisoang ka ho fetisisa bakeng sa ts'ebetso ea piston rod.

2. 40Cr tšepe
Haeba molamu oa piston o le tlas'a moroalo o boima, hangata o entsoe ka tšepe ea 40Cr.Kaha tšepe ea 40Cr ke tšepe e tingoeng ka har'a khabone e halefileng, e na le boima bo botle le ho hanyetsa mocheso o tlase.Haholo-holo ha e tingoa ebile e halefile, e ka ba le mekhoa e metle ea mochine ka kakaretso, 'me boima bo ka fihla pakeng tsa 32-36HRC, ke hore, pakeng tsa hoo e ka bang 301-340HB, e le hore molamu oa piston o ka ba le matla a sebetsang a khotsofatsang.Ka hona, lithupa tsa piston tse entsoeng ka tšepe ea 40Cr hangata li sebelisoa lithupeng tsa piston tse nang le tšusumetso e kholo le litlhoko tsa phetisetso e boima.

Litaba tse hlalositsoeng ka holimo ke lisebelisoa tse sebelisoang haholo bakeng sa ts'ebetso ea lithupa tsa piston.Leha ho le joalo, ntle le lisebelisoa tsena tse peli, tšepe ea GCr15, Sus304 ... joalo-joalo e boetse e sebelisoa ho etsa lisebelisoa tsa ho lokisa lithupa tsa piston.Ka hona, lisebelisoa tse sebelisetsoang ho lokisa lithupa tsa piston li khethoa haholo ho latela litlhoko tsa bona.Ka lebaka la lisebelisoa tse fapaneng, likarolong tse ling kapa litšoantšiso tse ling, li tla boela li be le melemo e fapaneng le lisebelisoa tse ling..
