Gulu la piston:
Popeza ma pistoni a injini zoyatsira mkati zimagwira ntchito pansi pa kutentha kwambiri, kuthamanga kwambiri komanso kulemedwa kwakukulu, zofunikira za pistoni ndizokwera kwambiri, kotero timalankhula makamaka za gulu la pistoni za injini zoyaka moto.
1. Malinga ndi mafuta omwe amagwiritsidwa ntchito, amatha kugawidwa m'mapistoni a injini ya petulo, ma pistoni a injini ya dizilo, ndi ma pistoni a gasi.
2. Malingana ndi pisitoniyo, ikhoza kugawidwa kukhala pisitoni yachitsulo, pisitoni yachitsulo, aluminium alloy piston ndi pistoni yophatikizana.
3. Malinga ndi ndondomeko yopanga pisitoni yopanda kanthu, imatha kugawidwa kukhala pisitoni yokoka, pisitoni yofinya ndi pisitoni.
4. Malingana ndi momwe pisitoni ikugwirira ntchito, ikhoza kugawidwa m'magulu awiri: pistoni yosakanizidwa ndi pisitoni yopanikizika.
5. Malinga ndi kugwiritsa ntchito ma pistoni, akhoza kugawidwa mu pisitoni zamagalimoto, ma pistoni amagalimoto, ma pistoni a njinga yamoto, ma pistoni apamadzi, ma pistoni a tank, ma pistoni a thirakitala, ma pistoni a lawnmower, ndi zina zotero.
Zofunika Zaukadaulo:
1. Payenera kukhala mphamvu zokwanira, kuuma, kulemera kwazing'ono ndi kulemera kochepa kuti kuwonetsetse mphamvu yochepa ya inertial.
2. Kutentha kwabwino kwa kutentha, kutentha kwapamwamba, kuthamanga kwapamwamba, kukana kwa dzimbiri, mphamvu yokwanira yotaya kutentha, ndi malo ochepa otentha.
3. Payenera kukhala kagawo kakang'ono kotsutsana pakati pa pisitoni ndi khoma la pistoni.
4. Pamene kutentha kumasintha, kukula ndi kusintha kwa mawonekedwe kuyenera kukhala kochepa, ndipo kusiyana kochepa kuyenera kusungidwa ndi khoma la silinda.
5. Coefficient yowonjezera kutentha ndi yaying'ono, mphamvu yokoka yeniyeni ndi yaying'ono, ndipo imakhala ndi kuchepetsa kuvala bwino komanso mphamvu zotentha.
Zogwirira ntchito:
Pistoni imagwira ntchito potentha kwambiri, kuthamanga kwambiri, kuthamanga kwambiri komanso kusapaka bwino.Pistoni imalumikizana mwachindunji ndi mpweya wotentha kwambiri, ndipo kutentha kwanthawi yomweyo kumatha kufika kupitilira 2500K.Choncho, kutentha kumakhala koopsa ndipo kutentha kwa kutentha kumakhala kosauka kwambiri, kotero kutentha kwa pistoni kumakhala kokwera kwambiri panthawi yogwira ntchito, pamwamba pake ndi 600-700K, ndipo kugawa kwa kutentha kumakhala kosiyana kwambiri;pamwamba pa pisitoni imagonjetsedwa Kuthamanga kwa mpweya ndi kwakukulu kwambiri, makamaka kupanikizika kwa sitiroko ndi kwakukulu kwambiri, injini ya mafuta ndi yokwera kwambiri mpaka 3-5MPa, ndipo injini ya dizilo ndi yokwera kwambiri mpaka 6-9MPa, zomwe zimapangitsa pisitoni imatulutsa mphamvu ndikunyamula zotsatira za kukakamiza kwa mbali;~ 12m / s) kuyendayenda kobwerezabwereza, ndipo liwiro limasintha nthawi zonse, zomwe zimapanga mphamvu yaikulu ya inertial, yomwe imapangitsa pisitoni kukhala ndi katundu wambiri wowonjezera.Pamene pisitoni imagwira ntchito movutikira chonchi, imapunduka ndikufulumizitsa kuvala, komanso imatulutsanso katundu wowonjezera komanso kupsinjika kwamatenthedwe, ndipo nthawi yomweyo imatenthedwa ndi mpweya.
Kuyang'anira pisitoni makamaka kuyeza kwa siketi ya siketi, kutalika kwa piston ring groove ndi kukula kwa dzenje la piston:
①Kusankhidwa kwa pistoni kuyenera kutsimikiziridwa molingana ndi kukula kwa silinda.Nthawi zambiri, kukula kokulirapo kumayikidwa pamwamba pa pistoni;
②Mu mndandanda womwewo wa zodyetsa nsomba, kapangidwe ka ma pistoni sikufanana kwenikweni.Chifukwa chake, pogula ma pistoni, mitundu yofananira ya pistoni iyenera kusankhidwa molingana ndi mtundu wa injini.Pa injini yomweyi, mtundu womwewo, gulu lomwelo kapena Pistons yokhala ndi code yofananira;chitsanzo chomwecho chiyenera kugwiritsa ntchito ma pistoni omwe ali ndi mankhwala omwewo kuti awonetsetse kuti kusiyana kwapakati ndi ubwino wa pisitoni sikudutsa kusiyana komwe kumatchulidwa ndi fakitale yoyamba.Kupanda kutero, zipangitsa injini kuyaka moyipa, kugwira ntchito movutikira, ndikuchepetsa chuma ndi mphamvu..Chifukwa chake, posankha pisitoni, mtundu wofananira wa pisitoni uyenera kusankhidwa molingana ndi mtundu wa injini.
