Indandatho ye-piston ibuyelana ne-piston kusilinda, okubangela ukuthi indawo yokusebenza yangaphandle yeringi ye-piston igqoke, ukushuba kwe-radial kwehla, futhi igebe phakathi kwezimbobo zokusebenza ze-piston liyakhula; Indawo ephansi yokugcina igugile, ukuphakama kwe-axial kwendandatho kuncipha, futhi igebe phakathi kwendandatho ne-groove ring, okungukuthi, igebe lendiza liyakhula. Ngokuvamile, izinga lokuguga elivamile leringi ye-piston lingaphakathi kuka-0.1-0.5mm/1000h lapho injini kadizili isebenza ngokujwayelekile, futhi ukuphila kweringi ye-piston ngokuvamile kuba ngu-8000-10000h. Indandatho yepiston evamise ukugqokwa igqoka ngokulinganayo eduze nendawo eyindilinga futhi isanamathele ngokugcwele odongeni lwesilinda, ngakho indandatho yepiston evamise ukugqokwa isenomphumela wokuvala. Kodwa empeleni, indawo yokusebenza yendilinga yangaphandle yeringi ye-piston igqokwa kakhulu ngokungalingani.
Ngaphambi kokulinganisa igebe phakathi kokuvuleka kweringi yepiston, ① khipha ipiston kusilinda, khipha iringi yepiston bese uhlanza indandatho yepiston kanye nesilinda liner. ② Faka amasongo e-piston eringini ye-piston engxenyeni engaphansi ye-cylinder liner noma ingxenye engagqokile engxenyeni engenhla ye-cylinder liner ngokohlelo lwamasongo e-piston ku-piston, futhi ugcine i-piston ikhala endaweni evundlile.
③ Sebenzisa igeji yokuzwa ukukala ukuvuleka kweringi yepiston ngayinye ngokulandelana. ④ Qhathanisa inani legebe elilinganiselwe lokuvula nesicaciso noma indinganiso. Uma inani lokuvunyelwa komkhawulo leqiwe, kusho ukuthi indawo engaphandle yeringi yepiston isigqokwe ngokweqile futhi kufanele kushintshwe entsha. Ngokuvamile kudingeka ukuthi inani lokuvula indandatho yepiston libe likhulu noma lilingane nemvume yomhlangano futhi lingaphansi komkhawulo wokuvunyelwa. Qaphela ukuthi uma igebe lokuvula lilincane kakhulu, alikwazi ukulungiswa ngokufaka ukuvulwa kweringi yepiston.
