Iringi yepiston isebenza kubushushu obuphezulu, uxinzelelo oluphezulu, isantya esiphezulu, kunye nemeko yokusebenza engasebenzi kakuhle. Kwangaxeshanye, kufuneka ibe nomsebenzi omhle wokutywina, ukukhuhla kweoli, kunye nemisebenzi yokuqhuba ubushushu. Kufuneka iqinisekise ukusebenza kwayo kokutywinwa kwaye ithintele umsesane wepiston ukuba ungabambeki kwiiGrooves kunye neesilinda, ngoko ke kufuneka kubekho izikhewu ezintathu xa ufaka umsesane wepiston.

Kukho izikhewu ezithathu eziza kulinganiswa xa i-piston ring ifakiwe, ezizezi, izithuba ezithathu zeringi yepiston ngokufutshane. Eyokuqala yi-gap yokuvula, eyesibini yi-axial gap (i-calo clearance), kwaye eyesithathu yi-gap ye-radial (i-gap yangasemva). Makhe sazise indlela yokulinganisa yeringi yepiston izikhewu ezithathu:

Umsantsa wokuvula
Ukuvulwa ngumsantsa weringi yepiston kunye nokuvulwa emva kokuba i-piston ring ifakwe kwi-cylinder ukuthintela umsesane wepiston ukuba ubambeke emva kokufudumeza kunye nokwandisa. Xa ujonga umsantsa wokuphela kweringi yepiston, faka umsesane wepiston kwicylinder kwaye uyityhale ngomphezulu wepiston. Emva koko linganisa isithuba kwindawo yokuvula ngegeyiji yobukhulu, ngokuqhelekileyo ngu-0.25 ~ 0.50mm. Ngenxa yobushushu obuphezulu bokusebenza, i-gap yokuphela kwendandatho yokuqala inkulu kuneyezinye iindandatho.

Umsantsa osecaleni
Umsantsa osecaleni ubhekiselele kumsantsa ongaphezulu nangaphantsi weringi yepiston kumjelo weringi. Umsantsa omninzi kakhulu wecala uya kuchaphazela isiphumo sokutywinwa kwepiston, umsesane omncinci kakhulu we-gap osecaleni uya kuncamathela kwi-ring groove. Ngexesha lokulinganisa, iringi yepiston ifakwa kwigroove yeringi kwaye ilinganiswe ngegeyiji yobukhulu. Ngenxa yobushushu obuphezulu bokusebenza, ixabiso leringi yokuqala ngokuqhelekileyo li-0.04 ~ 0.10mm, kwaye lelinye amakhonkco erhasi ngokuqhelekileyo li-0.03 ~ 0.07mm.I-gap esecaleni yeringi yeoli eqhelekileyo incinci, idla ngokuba yi-0.025 ~ 0.07mm, kwaye akukho msantsa osecaleni weringi yeoli edibeneyo.

Umva umsantsa
Umsantsa ongemva ubhekisa kumsantsa phakathi komva weringi yepiston kunye nomzantsi wepiston ring groove emva kokuba ipiston ifakwe kwicylinder. Ngokuqhelekileyo ibonakaliswa ngumahluko phakathi kobunzulu begroove kunye nobukhulu be-ring, obuyi-0.30 ~ 0.40mm ngokubanzi. Umsantsa ongemva wamakhonkco oyile oqhelekileyo mkhulu ngokwentelekiso. Umkhuba jikelele kukufaka iringi yepiston kwi-groove yeringi. Ukuba ingaphantsi kunebhanki yeringi, inokujikelezwa ngokukhululekileyo ngaphandle kokuziva ihlaba.
