Piston mphete.
Piston mphete (mphete ya piston) imagwiritsidwa ntchito poyambira pistoko mkati mwa mphete yachitsulo, mphete ya piston imagawidwa m'mitundu iwiri: kuphatikizika mphete ndi mphete yamafuta. Nnenete yosokoneza imatha kugwiritsidwa ntchito kusindikiza osakaniza mu chipinda cha kuyaka; Mphete yamafuta imagwiritsidwa ntchito popukutira mafuta owonjezera kuchokera pa silinda. Mphete ya piston ndi mtundu wa mphete yachitsulo yotupa yokhala ndi kuphatikizika kwakukulu kwakunja, komwe kumasonkhana mu mbiriyo ndi poyambira poofare. Kubwezeretsanso mphete za piston kudalira pang'onopang'ono kusiyana kwa mpweya kapena madzi kuti mupange chidindo pakati pa mphete yakunja ndi sing'anga ndi mbali imodzi ya mphete ndi poyambira mphete.
Ntchito ya mphete ya piston imaphatikizapo kusindikiza, mafuta oyendetsera mafuta (kuwongolera mafuta), kuphatikiza kutentha (kusamutsa kutentha), chitsogozo (chitsogozo) maudindo anayi. Kusindikizidwa: Kunena za kusindikiza mpweya, musalole kuyamwa kwa chipinda cha mpweya ku crankcase, kutulutsa kwa gasi kumayendetsedwa pang'ono, kusintha mphamvu ya mafuta. Kutulutsa kwa mpweya sikungangochepetsa mphamvu ya injini, komanso kumapangitsa kuwonongeka kwa mafuta, komwe ndi ntchito yayikulu ya mphete yamagesi; Sinthani mafuta (mafuta opangira mafuta) Mafuta owonjezera pa khoma la siliva amakambasulidwa ndi filimu yopyapyala kuti muwonetsetse kuti mafuta a silinda ndi pisitoni, yomwe ndi ntchito yayikulu ya mphete ya mafuta. M'matsenga amakono othamanga, chidwi chapadera chimalipira gawo la fiston mphete yowongolera mafuta; Kutentha kwa kutentha: Kutentha kwa pistoni kumafalikira kwa cylinder kuyamwa mphete ya piston, ndiye kuti, zotsatira zabwino. Malinga ndi deta yodalirika, 70 ~ 80% ya kutentha komwe adalandiridwa ndi piston pisiton yolumikizidwa ndi pisitoni yozizira imabalalitsidwa ndi mphete ya cugen; Chithandizo: Mphete ya piston imasunga pisitoni mu silindayo, imalepheretsa kulumikizana mwachindunji ndi khoma la cylinder, amalitse chipika cha pisitoni, ndipo chimalepheretsa pisitoni kugwetsa silinda. Nthawi zambiri, piston ya injini ya mafuta imagwiritsa ntchito mphete ziwiri ndi mphete imodzi yamafuta, pomwe injiniyo imagwiritsa ntchito mphete ziwiri ndi mphete imodzi yamafuta.
Njira yokonzanso mphete ya piston ili motere:
1. Choyamba muyenera kukhazikitsa mphete yamafuta, ndiye mphete yamafuta, dongosolo lili pansi;
2. Mphete iliyonse ikaikidwa, kutsegulidwa kwa mphete ya piston sikuyenera kuwonjezera kwambiri, kungokwanira kulowa mu piston;
3. Ikani mphete yophatikizidwa:
Ikani mphete ya little mu piston mafuta mphete, samalani ndi kutseguka kwa mphete ya Liner sikungatanga; Ikani mbale zam'munsi komanso zapamwamba popanda kugwiritsa ntchito zida zotsegula zotseguka. Mukakhazikitsa, kuyambira koyamba kwa mbale yotsika mu mphete, akanikizire malo otseguka ndi chala chanu, ndikupukutira chala cha dzanjali m'mphepete mwa mbaleyo, kenako ndikukweza mbale yachitsulo chimodzimodzi. Osakhazikitsa mbale zapamwamba kwambiri komanso zotsika mbali imodzi ya mphete ya limer; Pofuna kupewa kufikitsa zotseguka za limer pomwe piston amakankhidwira mu silinda, yozungulira kumtunda ndi kutsika kwa madigirimita 90 mpaka 120. Pambuyo pa kukhazikitsa, pang'onopang'ono kuzungulira mphete yamafuta yophatikizika ndi dzanja, ndipo ziyenera kukhala zosalala popanda.
4. Kukhazikitsa kwa mpweya:
Gwiritsani ntchito zida zapadera kukhazikitsa mphete ziwiri ndi mphete imodzi, musasinthe mphete yoyamba ya gasi ndi mphete yachiwiri; Mukayika, kumbali yalembedwa (hyr, hyr, csr, tlk, als, h, r, etc.). Ayenera kuyang'anana (piston mutu); Kubzala kutsegulidwa kwa mphete yamagesi 180, osatembenuzira kutsegulira kolowera pinsosani.
5. Musanapange mphete ya piston mu silinda, ndikofunikira kusintha malo otsegulira mphete iliyonse.
Ntchito ya RAPTON REFT:
1. Zotsatira
Mphete ya piston imatha kusunga chisindikizo pakati pa piston ndi khoma la cylinder, ndipo kutayikira kumayendetsedwa pang'ono, komwe kumanyamula mphete ya mpweya. Imatha kuletsa silinda ndi piston kapena silinder ndi mphete ya piston chifukwa cha kutaya kwa mpweya pakati pa kuluma; Zimatha kupewa zolephera zoyambitsidwa ndi kuthira mafuta kuwonongeka.
Gawo 2 pangani kutentha
Mphete ya piston imatha kusamutsa ndi kufalitsa kutentha kwakukulu komwe amapangidwa ndi khoma la silinda, ndipo amatha kutenga gawo pozizira piston.
3..
Mphete ya piston imatha kuloza mafuta opangira mafuta ophatikizidwa ndi khoma la silinda kuti lizikhala bwinobwino, zomwe zimanyamulidwa ndi mphete yamafuta.
4. Kuthandiza
Mphete ya piston imasunthika ndikutsika mu silinda, ndipo pomwepo malo ake oyenda amakulira mphete ya piston, kupewa pisitoni kuti igwirizane ndi silinda mwachindunji ndikugwira ntchito yothandiza.
Pali mitundu iwiri ya mphete za piston: mphete zamagesi ndi mphete zamafuta. Mphete yamagesi imagwiritsidwa ntchito kuonetsetsa chidindo pakati pa piston ndi silinda ndikusindikiza mpweya wothinikizidwa m'chipinda cha oyaka. Mphete yamafuta imagwiritsidwa ntchito potulutsa mafuta owonjezera pa silinda yowonjezera, yomwe imaletsa mafuta kuti asachokere mu silinda ndikuyaka.
Ngati mukufuna kudziwa zambiri, pitilizani kuwerenga nkhani zina patsamba lino!
Chonde ndiyitane ngati mukufuna zinthu ngati izi.
