Iimfuno zobugcisa zepiston

1. Iya kuba namandla aneleyo, ukuqina, ubunzima obuncinci, kunye nobunzima obulula ukuqinisekisa ubuncinci amandla angenayo.
2. Ukuqhuba kakuhle kwe-thermal, ukumelana nobushushu obuphezulu, uxinzelelo oluphezulu, ukuxhathisa kwe-corrosion, ukukwazi ukutshabalalisa ubushushu okwaneleyo, kunye nommandla omncinci wokufudumeza.
3. Kufuneka kubekho i-coefficient encinci ye-friction phakathi kwepiston kunye nodonga lwepiston.
4. Xa iqondo lokushisa litshintsha, ubukhulu kunye noshintsho lwemilo kufuneka lube luncinci, kwaye ubuncinci bokucoceka phakathi kodonga lwe-cylinder kunye ne-cylinder kufuneka lugcinwe.
5. I-coefficient ephantsi yokwandiswa kwe-thermal, i-gravity ethile encinci, ukunciphisa ukugqoka okulungileyo kunye namandla okushisa.

Indima yepiston
Ngeemfuno ezingqongqo ngakumbi zamandla, uqoqosho, ukukhuselwa kwendalo, kunye nokuthembeka kwenjini kwimoto yonke, ipiston iye yaphuhliswa yaba yimveliso yobuchwepheshe obuphezulu obudibanisa ubuchwephesha obuninzi obufana nobulula kunye nokuqina okuphezulu kwezixhobo ezintsha, ezikhethekileyo. -imigangatho ehlanganisiweyo ye-cylindrical, kunye nemingxuma ye-pin enemilo ekhethekileyo, ukuqinisekisa ukuxhathisa ukushisa, ukuxhathisa ukunxiba, isikhokelo esizinzile, kunye nomsebenzi wokutywina kakuhle wepiston, ukunciphisa ukulahleka komsebenzi we-injini, kunye nokunciphisa ukusetyenziswa kwamafutha Ingxolo kunye nokukhutshwa.
Ukuze kuhlangatyezwane nezi mfuno zingasentla zokusebenza, isangqa sangaphandle sepiston ngokuqhelekileyo siyilwe njengesangqa sangaphandle esinemilo ekhethekileyo (i-convex ukuya kwi-elliptical), oko kukuthi, icandelo lomnqamlezo li-perpendicular kwi-axis yepiston yi-ellipse okanye i-ellipse eguqulweyo, kunye nokuguquka kwe-ovality ecaleni kolwalathiso lwe-axis ngokomgaqo othile (njengoko kuboniswe kuMzobo 1), ngokuchaneka kwe-ovality ye-0.005mm;I-contour yangaphandle yecandelo le-piston longitudinal yi-curve efanelekileyo yomsebenzi womyalelo ophezulu, kunye nokuchaneka kwe-contour ye-0.005 kwi-0.01 mm;Ukuze kuphuculwe umthamo wokuthwala wepiston kunye nokunyusa amandla e-injini, umngxuma we-pin wepiston yomthwalo ophezulu udla ngokuyilwa njengohlobo lwekhowuni yangaphakathi encinci okanye uhlobo oluqhelekileyo lomphezulu olugobileyo (umngxuma wepin omilise okhethekileyo), kunye ukuchaneka kobungakanani bomngxuma we-IT4 kunye nokuchaneka kwe-contour ye-0.003mm.
I-Piston, njengecandelo eliphambili leemoto, ineempawu eziqinileyo zetekhnoloji kumatshini.Kumzi-mveliso wepiston wasekhaya, imigca yokuvelisa ngoomatshini idla ngokuqulunqwa zizixhobo zoomatshini ezisetyenziselwa iinjongo eziqhelekileyo kunye nezixhobo ezikhethekileyo ezidibanisa iimpawu zobugcisa bepiston.
Ngoko ke, izixhobo ezikhethekileyo ziye zaba zixhobo eziphambili ze-piston machining, kwaye umsebenzi wayo kunye nokuchaneka kuya kuchaphazela ngokuthe ngqo izikhombisi zekhwalithi zeempawu eziphambili zemveliso yokugqibela.
