Kodi Pini Ya Piston Pa Piston Imagwira Ntchito Bwanji?
2021-12-24
Ntchito ya pistoni ndi kugwirizanitsa pisitoni ndi mapeto ang'onoang'ono a ndodo yolumikizira, ndikufalitsa mphamvu pakati pa pisitoni ndi ndodo yolumikizira.
Piston imanyamula katundu wodabwitsa nthawi ndi nthawi, ndipo imadzizungulira yokha, ndipo imagwira ntchito pansi pa mafuta osakwanira. Chifukwa chake, pini ya pisitoni imayenera kukhala ndi mphamvu zokwanira komanso kulimba, kulimba kwapamwamba, kukana kuvala bwino, komanso kulemera kopepuka. Zikhomo za pistoni nthawi zambiri zimapangidwa ndi masilinda opanda kanthu, opangidwa ndi chitsulo chochepa cha carbon and low carbon alloy steel. Kunja kwakunja ndi carburized ndi kuzimitsidwa kuonjezera kuuma. Akamaliza, amapukutidwa kuti akhale olondola kwambiri komanso omaliza.
Mapangidwe a piston ya piston ndi thupi lolimba lokhala ndi mipanda, ndipo ena amakhala ndi magawo osinthika molingana ndi zofunikira za mphamvu zofanana.
Pali njira ziwiri zolumikizira piston ku dzenje la mpando wa pisitoni ndi ndodo yolumikizira yaing'ono kumapeto kwa bowo: kulumikizana koyandama komanso kulumikizana koyandama.
Kulumikizana koyandama kumatanthauza kuti injini ikakhala pa kutentha kwanthawi zonse, pini ya pistoni imatha kuzungulira momasuka mu dzenje la mpando wa piston ndi ndodo yolumikizira kabowo kakang'ono kamutu. Monga momwe tawonetsera pachithunzichi, ndi kugwirizana koyandama, pini ya pistoni imatha kupirira katundu wambiri, kuvala mofanana, ndikukhala ndi moyo wautali wautumiki, koma ndondomeko ya msonkhano imakhala yovuta kwambiri. Mukasonkhanitsa pisitoni ya aluminium alloy piston ndi piston, piston iyenera kutenthedwa m'madzi kapena mafuta pa kutentha kwa 70-90 ℃ kukulitsa dzenje la mpando wa piston musanayike piston. Pofuna kupewa kuzungulira kwa axial kwa pini ya pistoni, mphete zowonongeka zimayikidwanso kumapeto kwa mpando wa pini.
Kulumikizana koyandama kumatanthauza kuti malo amodzi amakhazikika pakati pa piston ndi bowo la mpando wa piston ndi ndodo yolumikizira kabowo kakang'ono komaliza. Pini ya pistoni yokhazikika imayikidwa ku ndodo yolumikizira mapeto ang'onoang'ono.Mabotolo omwe amasonyezedwa amakonzedwanso ndi pini ya pistoni ndi mapeto ang'onoang'ono a ndodo yolumikizira mwa kusokoneza koyenera. Popeza palibe kusuntha kwapakati pakati pa piston ndi ndodo yolumikizira, palibe chifukwa choti mphete yolumikizira iletse malo a axial a piston, ndiko kuti, piston yoyandama yolumikizana ilibe mphete, ndipo pamenepo. palibe bushing kumapeto kwakung'ono kwa ndodo yolumikizira. Pini ya piston yoyandama imatha kuchepetsa phokoso la injini ndikuchotsa ngozi zomwe zingachitike chifukwa cha mphete yojambulira. Amagwiritsidwa ntchito kwambiri pamainjini opepuka othamanga kwambiri, monga Cherokee ndi Cheetah, ndi zina zambiri magalimoto amatengera mawonekedwe awa.
