Umsesane wepiston ubhekisa kumsesane wentsimbi ofakwe kwi-piston groove kwizincedisi zeforklift. Kukho iintlobo ezininzi zamakhonkco episton ngenxa yezakhiwo ezahlukeneyo, ngakumbi amakhonkco oxinzelelo kunye nemisesane yeoli. Ukuqhekeka kweringi yepiston yindlela yomonakalo eqhelekileyo yamakhonkco episton. Enye, ngokuqhelekileyo, iipaseji zokuqala nezesibini zeringi yepiston zezona ziqhekekileyo ngokulula, kwaye uninzi lwamacandelo aphukileyo asondele kumjikelo.

Iringi yepiston inokohlulwa ibe ngamacandelo amaninzi, kwaye isenokwaphulwa okanye ide ilahleke. Ukuba umsesane wepiston wophukile, oko kuya kukhokelela ekwandeni kokuguga kwesilinda, kwaye iringi eyaphukileyo ye-injini inokuvuthelwa kumbhobho wokukhupha okanye kwibhokisi yomoya emdaka, okanye nakwi-turbocharger. kunye nokuphela kweinjini yomoya, zonakalisa iincakuba ze-iturbine kwaye kubangele iingozi ezimandundu!

Ukongeza kwiziphene eziphathekayo kunye nomgangatho ophantsi wokulungisa, izizathu zokuqhekeka kwamakhonkco episton ikakhulu zezi zizathu zilandelayo:

1. Umsantsa welap phakathi kweringi zepiston umncinci kakhulu. Xa i-gap ye-lap ye-piston incinci kune-gap phakathi kwee-assemblies, i-piston ring esebenzayo iya kutshisa kwaye iqondo lokushisa liya kunyuka, ngoko akukho ndawo eyaneleyo ye-lap gap. Intsimbi ephakathi idumba kwaye iziphelo zeelaps zigoba ukuya phezulu kwaye ziphuke kufuphi nedolo.

2. Iidiphozithi zekhabhoni kwi-piston ring groove Ukutsha kakubi kwamakhonkco episton kukhokelela ekugqithiseni kodonga lwe-cylinder, okwenza ukuba i-oyile yokuthambisa i-oxidize okanye itshise, ekhokelela ngakumbi ekuqokeleleni okukhulu kwekhabhoni kwi-cylinder. Ngenxa yoko, i-piston ring kunye nodonga lwe-cylinder lunobudlelwane obuqinileyo, i-oyile yokukrazula kunye nenkunkuma yensimbi ixutywe, kwaye iidiphozithi ezinzima zendawo zenziwe kwindawo ephantsi ye-groove ye-ring groove, kwaye kukho ithuba lekhabhoni elinzima lendawo phantsi. umsesane wepiston. Uxinzelelo lwerhasi ejikelezayo yenza ukuba iiringi zepiston zigobe okanye ziphuke.

3. I-ring groove yeringi yepiston inxitywe ngokugqithisileyo. Emva kokuba i-ring groove yeringi yepiston inxitywe ngokugqithiseleyo, iya kwenza imilo yophondo. Xa i-piston ring isondele kwisiphelo esisezantsi se-ring groove ethambekele ngenxa yesenzo soxinzelelo lomoya wokumisa, i-piston ring iya kuguqulwa kwaye ikhubazeke, kwaye ipiston iya kuba yinto engafanelekanga. I-ring groove iya kunxitywa kakhulu okanye itshatyalaliswe.

4. Ukunxitywa okunzulu kweringi yepiston kunye ne-cylinder liner kwindawo ephezulu kunye nesezantsi amaziko afileyo kwindandatho yepiston, kwaye kulula ukuvelisa ukunxiba okunyathelweyo kwaye kubangele amagxa. Xa isiphelo esikhulu sentonga yokudibanisa sigqitywe okanye isiphelo sokuqala sentonga yokudibanisa silungiswa, indawo yokuqala yokufa iya konakaliswa. Isikhundla sitshintshile kwaye i-shock ring ibangelwa amandla angenayo.
