Izindandatho ze-Piston eziphukile! Lezi imvamisa zibangela.

Izimbangela ezijwayelekile ze-Piston Riston izindandatho: Ngaphezu kweziphambeko ezibonakalayo kanye nekhwalithi yemishini engenzi kahle, ukunakekelwa okungekuhle kanye nomhlangano kuyimbangela enkulu.

Ukuvunyelwa kwe-Overlap kuncane kakhulu.

Lapho imvume yokugcwala incane ukwedlula ukukhishwa komhlangano, indandatho ye-piston ishisa ngesikhathi sokusebenza, ishiya indawo enganele yokunwetshwa kwensimbi ekwandiseni. Lokhu kubangela ukuphela kokugcwala kugoqeke ngokumelene komunye nomunye bese uhlukana eduze kokugqekeza.

Idiphozi yekhabhoni endabeni yendandatho.

Ukuvutha okumpofu, ukugcwala ngokweqile kodonga lwe-cylinder, oxidation of the uwoyela wokuthambisa, noma ukushiswa konke kungaholela kumadiphozi kakhudlwana ekhabhoni kwisilinda. Idiphozi enzima yekhabhoni ithinte ukunyakaza kwendandatho, okubangela ukuxhumana okuqinile phakathi kwendandatho nodonga lwesilinda. Ukuxubana okugcoba ukuxutshwa kwamafutha ngama-metal chips ngama-metal chips, futhi igesi yokuphelelwa yi-efter ekhishini yekhabhoni eyakhiwe endaweni ephansi yokuphela kokuphela kwendandatho. Idiphozi yekhabhoni eyakhiwe endaweni ephansi yendandatho ephansi yendandatho yepiston ingathinteka ngokucindezela kwegesi ngezikhathi ezithile, okwenza ukuthi i-piston riston iphule ngenxa yokukhathala kokugoba.

Ukunyakaza okuhlobene isikhathi eside phakathi komhlangano wePiston kanye ne-cylinder liner kungadala ukuthi i-cylinder liner ukugabha, okuholele ekutheni kube ngu-slab endaweni engenhla ye-cylinder liner. Lapho i-piston ifinyelela esikhungweni esifile esiphezulu, indandatho yokuqala ye-piston ishayisa itafula lokugaya, liphule ngenxa yomthelela.

Ukugqoka ngokweqile kwe-groove yendandatho

Ukugqoka ngokweqile kwendawo ephansi yokuphela kwendandatho groove kubangela ukuthi igange (yavutha). Lapho i-piston iseduze nendawo ephezulu efile, i-combustion gesi ingcindezi iphoqa ukuthi indandatho icindezele ngokumelene nendawo ephansi ephansi ye-groove, okwenza ukuthi indandatho yepiston ihlasele.
