Umphezulu wangaphakathi we-cylinder liner uchaphazeleka ngokuthe ngqo kubushushu obuphezulu kunye noxinzelelo oluphezulu lwegesi, kwaye uhlala une-speed sliding friction kunye ne-piston ring kunye ne-piston skirt.Umphezulu udibana namanzi okupholisa, okukhokelela kuxinzelelo olunzima lwe-thermal phantsi komlinganiselo omkhulu weqondo lokushisa, kwaye uhlanjululwe ngamanzi okupholisa.Ukutyhala kwecala kwepiston kwi-cylinder liner ayinyusi nje ukukhuhlana komphezulu wangaphakathi, kodwa ikwabangela ukuba igobe.I-piston iphinda ibethe i-cylinder liner xa i-thrust esecaleni itshintsha indlela.Ukongeza, ixhomekeke kufakelo olukhulu lwangaphambili.
Uxinzelelo lwegesi luvelisa uxinzelelo lwe-tangential kunye noxinzelelo lwe-radial compressive eludongeni lwesilinda, kwaye yeyona inkulu kumphezulu ongaphakathi, zonke ezi ziluxinzelelo oluphezulu lwe-pulsating.
Ngenxa yoxinzelelo olukhulu lwe-thermal olubangelwa ngumahluko weqondo lokushisa phakathi kwangaphakathi nangaphandle kwodonga lwe-cylinder, uxinzelelo oluxinzelelekileyo lwenzeka kwindawo yangaphakathi kunye noxinzelelo lwe-tensile lukhona kwindawo yokupholisa phantsi kobushushu obuqhelekileyo.Nangona kunjalo, phantsi kobushushu obuphezulu kakhulu, isinyithi esikufutshane nomgangatho ongaphakathi siya kutyhutyha iplastiki, kwaye emva kokupholisa, uxinzelelo olushiyekileyo luya kwenziwa kumphezulu ongaphakathi.Olu xinzelelo lwe-frequency ephantsi olubangelwa ukuqala kunye nokuyeka utshintsho luya kubangela ukudinwa kwezinto.
I-cylinder liner kufuneka ibe namandla okwaneleyo, ukuqina kunye nokumelana nokushisa, kunye nokumelana nokunxiba kakuhle.Kufuneka kubekho ukuthambisa okulungileyo kunye nokupholisa ngexesha lomsebenzi.
I-cylinder liner ngokuqhelekileyo yenziwe nge-alloy-resistant alloy cast iron cast equkethe i-phosphorus okanye i-boron, efana ne-HT25-47, HP-CuCrMo, njl njl. Umphezulu wangaphakathi we-cylinder liner ngamanye amaxesha uphathwa nge-chrome plating (i-chrome plating kwimingxuma evulekileyo; i-chrome plating kwiindawo zokugcina ioli), i-nitriding okanye i-phosphating ukuphucula ukuxhathisa ukunxiba.Ubulukhuni bangaphakathi bomphezulu we-cylinder liner ngokuqhelekileyo bufuneka ukuba bube bukhulu kune-HB200, kwaye buhambelana kakuhle nobunzima beringi yepiston.Umphezulu wangaphakathi kufuneka ube noburhabaxa obufanelekileyo, ukuze ube nomthamo othile wokugcina ioyile kunye nokusebenza okusebenzayo.Umphezulu wangaphakathi kufuneka ube nokujikeleza okwaneleyo kunye nokuchaneka kwe-cylindricity, kunye nenkxaso yokunyuka ejongene nombindi womngxuma wangaphakathi kufuneka ibe nokuchaneka okuphezulu kwesikhundla.
