Umsesane wepiston ubuyisela kunye nepiston kwi-cylinder, ebangela ukuba indawo yokusebenza yangaphandle yeringi yepiston inxibe, ubukhulu be-radial bomsesane buyancipha, kwaye umsantsa phakathi kokuvuleka kokusebenza komsesane wepiston uyanda; Umphezulu wesiphelo esisezantsi ugugile, ukuphakama kwe-axial kwindandatho kuncipha, kwaye i-gap phakathi kwendandatho kunye ne-groove ye-ring, oko kukuthi, i-gap yendiza iyanda. Ngokuqhelekileyo, izinga lokunxiba eliqhelekileyo leringi yepiston lingaphakathi kwe-0.1-0.5mm/1000h xa injini yedizili isebenza ngokuqhelekileyo, kwaye ubomi beringi yepiston ngokuqhelekileyo 8000-10000h. Iringi yepiston edla ngokunxitywa inxiba ngokulinganayo ecaleni kwendlela ejikelezayo kwaye isancanyathiselwe ngokupheleleyo kudonga lwesilinda, ngoko ke umsesane wepiston oqhele ukunxitywa usenesiphumo sokutywinwa. Kodwa eneneni, umphezulu wokusebenza wesangqa sangaphandle seringi yepiston ubukhulu becala inxitywa ngokungalingani.
Phambi kokulinganisa umsantsa phakathi kokuvuleka kweringi yepiston, ① khupha ipiston kwicylinder, susa umsesane wepiston kwaye ucoce umsesane wepiston kunye necylinder liner. ② Faka amakhonkco episton kwikhonkco yepiston kwindawo encinci enxitywayo yecandelo elisezantsi le-cylinder liner okanye indawo enganxibanga yendawo ephezulu ye-cylinder liner ngokomyalelo wamakhonkco episton kwipiston, kwaye ugcine. amakhonkco ipiston kwindawo ethe tye.
③ Sebenzisa igeyiji yokulinganisa ukuvuleka kweringi yepiston nganye ngokulandelelanayo. ④ Thelekisa ixabiso le-gap elilinganisiweyo kunye neenkcukacha okanye umgangatho. Xa ixabiso lokuvunyelwa komda ligqithisiwe, oko kuthetha ukuba umphezulu wangaphandle weringi yepiston ugqitywe ngokugqithiseleyo kwaye kufuneka utshintshwe ngokutsha. Ngokuqhelekileyo kuyafuneka ukuba ixabiso lokuvula i-piston ring likhulu kunokuba okanye lilingana nokukhutshwa kwendibano kwaye lingaphantsi kwemvume elinganiselweyo. Qaphela ukuba i-gap yokuvula incinci kakhulu, ayikwazi ukulungiswa ngokufaka i-piston ring open.
