1. 45# insimbi
Ngaphansi kwezimo ezijwayelekile, uma umthwalo wenduku ye-piston ungemkhulu kakhulu, insimbi engu-45# ngokuvamile isetshenziselwa ukukhiqiza.Njengoba insimbi engu-45# iyinsimbi evamise ukusetshenziswa ephakathi nendawo ecishiwe futhi enomoya ophansi, inamandla aphezulu kanye nokusebenza kahle komshini, ikakhulukazi uma ifreyimu ye-roller eshiselwe idlule ukwelashwa kokushisa kwegesi, ingathola ukumelana okuthile., ipulasitiki nokumelana nokugqoka, ngakho-ke ingenye yezinto ezisetshenziswa kakhulu ekucubunguleni induku ye-piston.
2. 40Cr insimbi
Uma induku yepiston ingaphansi komthwalo osindayo, ngokuvamile yenziwa ngensimbi engu-40Cr.Njengoba insimbi engu-40Cr iyinsimbi ecishiwe ephakathi nendawo, inokuqina okuhle kanye nokumelana nomthelela ophansi wokushisa.Ikakhulukazi lapho icishwa futhi ithukuthele, ingaba nezakhiwo ezinhle kakhulu zemishini evamile, futhi ubulukhuni bungafinyelela phakathi kuka-32-36HRC, okungukuthi, phakathi kwe-301-340HB, ukuze i-piston rod ibe namandla okusebenza agculisayo.Ngakho-ke, izinti ze-piston ezenziwe ngensimbi engu-40Cr zivame ukusetshenziswa ezindongeni zepiston ezinamandla amakhulu omthelela kanye nezidingo zokudlulisa umthwalo osindayo.
Okuqukethwe okuchazwe ngenhla yizinto ezisetshenziswa kakhulu zokucubungula i-piston rod.Kodwa-ke, ngaphezu kwalezi zinto ezimbili, i-GCr15 steel, i-Sus304… njll. iphinde isetshenziswe ukwenza izinto zokucubungula induku ye-piston.Ngakho-ke, izinto ezisetshenziselwa ukucutshungulwa kwezinduku ze-piston zikhethwa ngokuyinhloko ngokwezidingo zabo.Ngenxa yezinto ezihlukene, kwezinye izici noma okunye ukusebenza, bazoba nezinzuzo ezithile ezihlukile kwezinye izinto..
