Kudziwa zina za pistoni

Piston ndi kayendedwe kobwerezabwereza mu thupi la silinda la injini yamagalimoto. Mapangidwe a pistoni amatha kugawidwa pamwamba, mutu ndi siketi. Pamwamba pa pisitoni ndi gawo lalikulu la chipinda choyaka moto, ndipo mawonekedwe ake amagwirizana ndi mawonekedwe osankhidwa a chipinda choyaka moto. Ma injini a petulo nthawi zambiri amagwiritsa ntchito pisitoni yosalala pamwamba, yomwe ili ndi mwayi wamalo ang'onoang'ono amayamwitsa kutentha. Pistoni ya injini ya dizilo nthawi zambiri imakhala ndi maenje osiyanasiyana, mawonekedwe ake enieni, malo ake ndi kukula kwake ziyenera kukhala ndi mapangidwe osakaniza a injini ya dizilo ndi zofunikira kuyaka.

Chifukwa pisitoni ya injini yoyaka yamkati imagwira ntchito pansi pa kutentha kwambiri, kupanikizika kwambiri komanso kulemedwa kwakukulu, zofunikira za pisitoni ndizokwera kwambiri, motero pisitoni ya injini yoyaka mkati imakambidwa makamaka.
1. Malingana ndi mafuta omwe amagwiritsidwa ntchito, amatha kugawidwa mu pistoni ya injini ya petulo, pistoni ya injini ya dizilo, pistoni ya gasi.
2. Malinga ndi zida za pisitoni, imatha kugawidwa kukhala pisitoni yachitsulo, pisitoni yachitsulo, aluminium alloy piston ndi pistoni yophatikizika.
3. Malinga ndi ndondomeko yopangira pisitoni zosowekapo, zitha kugawidwa kukhala pisitoni yokoka, pisitoni yoponyera pisitoni ndi pisitoni yabodza.
4. Malingana ndi momwe pisitoni ikugwirira ntchito, ikhoza kugawidwa m'magulu awiri: pistoni yosakanizidwa ndi pistoni yopanikizidwa.
5. Malinga ndi cholinga cha pisitoni, ikhoza kugawidwa mu pisitoni yagalimoto, pisitoni yagalimoto, pisitoni yamoto, Marine piston, tank piston, thirakitala piston, lawn mower piston, etc.

Ndi mphamvu ya injini yamagalimoto, chuma, chitetezo cha chilengedwe komanso kudalirika ndizofunikira kwambiri, pisitoni yasanduka chinthu chamakono chophatikizira zida zatsopano zopepuka komanso zamphamvu kwambiri, mawonekedwe apadera a cylindrical composite surface, mapini ooneka ngati apadera. ndi matekinoloje ena atsopano kuti atsimikizire kukana kutentha, kukana kuvala, kuwongolera bwino komanso ntchito yabwino yosindikiza pisitoni. Chepetsani kuwonongeka kwa ntchito ya injini, kuchepetsa kugwiritsa ntchito mafuta, phokoso komanso kutulutsa mpweya. Kuti akwaniritse zofunikira zomwe zili pamwambazi, bwalo lakunja la pisitoni nthawi zambiri limapangidwa ngati mawonekedwe apadera akunja (convex variable ellipse), ndiye kuti, gawo la mtanda loyang'ana mbali ya pisitoni ndi ellipse kapena ellipse yokonzedwa, ndi elliptical amasintha motsatira axis malinga ndi lamulo linalake (monga momwe tawonetsera pa Chithunzi 1), ndipo kulondola kwa ellipticity ndi 0.005mm; Mzere wakunja wa gawo lotalikirapo la pistoni ndi wokhotakhota woyenera wa magwiridwe antchito apamwamba, ndipo kulondola kwa contour ndi 0.005 ~ 0.01mm. Pofuna kupititsa patsogolo mphamvu ya pistoni ndikuwonjezera mphamvu ya lita imodzi ya injini, mabowo a piston a pistoni yodzaza kwambiri nthawi zambiri amapangidwa kukhala mtundu wamkati wamkati wamkati kapena mtundu wokhazikika wopindika (mabowo apadera a pini), kukula kwake. Mabowo a pini ndi mulingo wa IT4, ndipo kulondola kwa contour ndi 0.003mm. Monga mbali yofunika kwambiri yagalimoto, piston ili ndi ukadaulo wamphamvu pakudula. Makampani opanga pisitoni nthawi zambiri amakhala ndi zida zamakina ndi zida zapadera zomwe zimaphatikizidwa ndi mawonekedwe a piston process Machining line, chifukwa chake, zida zapadera zakhala zida zofunika kwambiri pakudulira pisitoni, ndipo ntchito yake ndi kulondola kwake zidzakhudza mwachindunji zizindikiro za khalidwe la makhalidwe ofunikira a chinthu chomaliza.
