Ntchito ya pini ya pistoni
Ntchito yaikulu ya pini ya pistoni ndikulumikiza pistoni ndi ndodo yolumikizira kuti isamutse mphamvu ya mpweya yonyamulidwa ndi pistoni. Pini ya pistoni ndi pini yozungulira yomwe imayikidwa pamphepete mwa pistoni, yomwe gawo lake limadutsa m'bowo laling'ono la ndodo yolumikizira. Imagwiritsidwa ntchito kulumikiza pistoni ndi ndodo yolumikizira, ndikusamutsa mphamvu ya mpweya yonyamulidwa ndi pistoni kupita ku ndodo yolumikizira.
Kapangidwe ndi mfundo yogwirira ntchito
Ma pini a pistoni nthawi zambiri amaikidwa mu mawonekedwe oyandama kapena oyandama pang'ono. Pini yonse yoyandama ya pistoni imatha kuzungulira momasuka pakati pa mutu waung'ono wa ndodo yolumikizira ndi mpando wa pistoni, pomwe pini yoyandama pang'ono imakhazikika pamutu waung'ono wa ndodo yolumikizira. Pini ya pistoni imakhudzidwa ndi mphamvu nthawi ndi nthawi ikakhala ikugwira ntchito, ndipo imayenda ndi pendulum, kotero imafunika kukhala ndi mphamvu zabwino komanso kukana kuwonongeka.
Zipangizo ndi njira zopangira
Pofuna kuchepetsa kulemera, ma pini a pistoni nthawi zambiri amapangidwa ndi chitsulo chapamwamba kwambiri cha alloy ndipo nthawi zambiri amapangidwa ndi kapangidwe kopanda kanthu. Kapangidwe kameneka sikuti kamangochepetsa kulemera kokha, komanso kamawonjezera kukana kwake kutopa.
Kodi pini ya pistoni nthawi zambiri imapangidwa ndi zinthu ziti?
Chitsulo chotsika cha kaboni, chitsulo chotsika cha aloyi cha kaboni
Ma pini a pistoni nthawi zambiri amapangidwa ndi chitsulo chopanda mpweya kapena chitsulo chopanda mpweya. Mwachitsanzo, zitsulo za 15, 20, 15Cr, 20Cr ndi 20Mn2 zimagwiritsidwa ntchito kwambiri m'mainjini omwe ali ndi katundu wochepa; Mu injini yolimbikitsidwa, kugwiritsa ntchito chitsulo chopanda mpweya chapamwamba, monga 12CrNi3A/18CrMnTi2 ndi 20SiMnVB, nthawi zina kungagwiritsidwenso ntchito chitsulo chapakati cha kaboni cha 45.
Kusankha zinthu za pini ya piston kumadalira kwambiri momwe imagwirira ntchito komanso zofunikira pa kapangidwe kake. Pini ya piston imakhudzidwa kwambiri nthawi ndi nthawi ndi kutentha kwambiri, ndipo chifukwa chakuti ngodya yozungulira ya pini ya piston mu dzenje la pini si yayikulu, zimakhala zovuta kupanga filimu yopaka mafuta, kotero kuti mafuta ake ndi oipa. Kuti akwaniritse zofunikirazi, pini ya piston iyenera kukhala yolimba, yolimba komanso yolimba mokwanira. Kusankha zipangizo kuyenera kuonetsetsa kuti pamwamba pa pini ya piston pali kuuma kwakukulu kuti ikwaniritse zosowa za mphamvu yayikulu yamakina komanso kukana kutopa.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
