Kukho iintlobo ezimbini zemisesane yepiston yokulungisa injini:ubungakanani obuqhelekileyo kunye nobukhulu obandisiweyo. Kufuneka sikhethe umsesane wepiston ngokwesayizi yangaphambili yokusetyenzwa kwe-cylinder. Ukuba i-piston ring yesayizi engalunganga ikhethiwe, isenokungafanelanga, okanye isithuba phakathi kwamacandelo sikhulu kakhulu. Kodwa kule mihla uninzi lwazo zinobungakanani obuqhelekileyo, ezimbalwa zazo zandisiwe.

Ukuhlolwa kwe-elasticity yeringi yepiston:I-elasticity yeringi yepiston yenye yeemeko ezibalulekileyo zokuqinisekisa ukuqina kwe-cylinder. Ukuba i-elasticity inkulu kakhulu okanye incinci kakhulu, ayilungile. Kufuneka ihlangabezane neemfuno zobugcisa. Umvavanyi weringi wepiston usetyenziselwa ukubonwa. Ngokwesiqhelo sisebenzisa isandla ukugweba ngokurhabaxa, logama nje singakhululekanga kakhulu, sinokusetyenziswa.

Ukuhlolwa kokuvuza kokukhanya kweringi yepiston kunye nodonga lwesilinda:Ukuze uqinisekise isiphumo sokutywinwa kweringi yepiston, indawo yangaphandle yeringi yepiston iyafuneka ukuba idibane nodonga lwesilinda kuyo yonke indawo. Ukuba ukuvuza kokukhanya kukhulu kakhulu, indawo yokunxibelelana yendawo yeringi yepiston incinci, enokuthi ikhokelele ngokulula ekuvuthelweni ngokugqithisileyo kwerhasi kunye nokusetyenziswa kakhulu kweoyile. Kukho izixhobo ezikhethekileyo zokubona ukuvuza kokukhanya kweringi yepiston. Iimfuno jikelele zezi: akukho kuvuza ukukhanya kuvunyelwe ngaphakathi kwe-30 ° yesiphelo esivulekileyo seringi yepiston, kwaye akukho kuvuza kokukhanya okungaphezulu kwesibini kuvunyelwe kwiringi yepiston efanayo. I-engile yeziko ehambelanayo kufuneka ingadluli i-25 °, i-engile yeziko elipheleleyo elihambelana nobude be-arc yokuvuza kwi-arc efanayo yepiston kufuneka ingadluli i-45 °, kwaye isithuba sokuvuza kokukhanya kufuneka singadluli i-0.03mm. Ukuba ezi mfuno zingasentla azifezekanga, kufuneka ukhethe kwakhona i-piston ring okanye ulungise isilinda.

Kubalulekile ukuba uqaphele ukuba ngaphambi kokuba i-piston ring ifakwe, kuyimfuneko ukugqiba ukuba i-cylinder liner nayo i-chrome-plated.Ukuba ubuso be-piston ring kunye ne-cylinder liner ziye zafakwa nge-chrome-plated, kulula ukuvelisa i-phenomenon. yamanqaku eSilinda.
