Ingaphakathi le-cylinder liner lithinteka ngokuqondile izinga lokushisa eliphezulu kanye negesi yokucindezela okukhulu, futhi lihlale linesivinini sokuslayida ngendandatho ye-piston kanye nesiketi se-piston.Ingaphezulu lithintana namanzi okupholisa, okuholela ekucindezelekeni okukhulu kokushisa ngaphansi komehluko omkhulu wezinga lokushisa, futhi kugqwelwe amanzi apholisayo.I-side thrust ye-piston ku-cylinder liner ayikhulisi nje kuphela ukungqubuzana kwendawo yangaphakathi, kodwa futhi ibangela ukuthi igobe.I-piston iphinde ishaye i-cylinder liner uma i-thrust eseceleni ishintsha indlela.Ngaphezu kwalokho, ingaphansi kokulayisha kuqala kokufakwa okukhulu.
Ingcindezi yegesi ikhiqiza ingcindezi ye-tangential tensile kanye ne-radial compressive stress odongeni lwesilinda, futhi inkulu kakhulu endaweni engaphakathi, konke okuyingcindezi yokushaya ngamandla kwe-high-frequency.
Ngenxa yengcindezi enkulu yokushisa ebangelwa umehluko wezinga lokushisa phakathi kwangaphakathi nangaphandle kodonga lwesilinda, ingcindezi ecindezelayo ivela endaweni engaphakathi futhi ingcindezi eqinile ikhona endaweni epholile ngaphansi kwezinga lokushisa elivamile.Kodwa-ke, ngaphansi kwezinga lokushisa eliphakeme kakhulu, insimbi eseduze nendawo engaphakathi izoshintshashintsha, futhi ngemva kokupholisa, ukucindezeleka okusalayo kuyokwakhiwa endaweni engaphakathi.Lokhu kucindezeleka kwemvamisa ephansi okubangelwa ukuqala nokumisa izinguquko kuzodala ukukhathala kwezinto.
I-cylinder liner kufanele ibe namandla anele, ukuqina nokumelana nokushisa, kanye nokumelana okuhle kokugqoka.Kufanele kube nokugcotshwa okuhle nokupholisa ngesikhathi somsebenzi.
I-cylinder liner ngokuvamile yenziwe ngensimbi engagugi ye-alloy cast equkethe i-phosphorus noma i-boron, efana ne-HT25-47, HP-CuCrMo, njll. Indawo engaphakathi ye-cylinder liner ngezinye izikhathi iphathwa nge-chrome plating (i-chrome plating ezimbotsheni ezivulekile, i-chrome plating ezindaweni zokugcina uwoyela), i-nitriding noma i-phosphating ukuthuthukisa ukumelana nokugqoka.Ubulukhuni bobuso bangaphakathi be-cylinder liner ngokuvamile budingeka bube bukhulu kune-HB200, futhi buhambisana kahle nobulukhuni beringi ye-piston.Indawo engaphakathi kufanele futhi ibe nobuhwaqaqe obufanele, ukuze ibe nomthamo othile wokugcina uwoyela kanye nokusebenza okusebenzayo.Indawo engaphakathi kufanele ibe nendingilizi eyanele kanye nokunemba kwe-cylindricity, futhi isisekelo sokukhweza esibheke phakathi nendawo yembobo yangaphakathi kufanele sibe nokunemba okuphezulu kokuma.
