Disassembly wa piston yolumikiza ndodo gulu
Ngati galimoto yanu yayimitsidwa m'madzi, chonde musakakamize kuyatsa, chifukwa madzi akakhala apamwamba kuposa mpweya wa injini, madziwo amalowa mwachindunji mu silinda, kupanga madzi osakaniza osakaniza, mpweya ukhoza kupanikizidwa, ndi madzi. sungakhoze kupanikizidwa.Injini ikakhala m'madzi ndipo crankshaft ikankhira ndodo yolumikizira kuti ikanikizire pisitoni, madzi sangapanikizidwe.Pambuyo pa ndodo yolumikizirayo ikakumana ndi kukana kwa madzi, imapunduka ndikupindika, kapena kusweka.
1. Njira zodzitetezera ku disassembly
① Fumbi lakunja liyenera kuchotsedwa musanayambe disassembly, yang'anani mosamala ndikukumbukira malo ndi chizindikiro cha gawo lililonse lomwe lasokonekera.
② Musanatulutse ndodo yolumikizira pisitoni, chopondapo cha kaboni chakumtunda kwa cylinder liner chiyenera kupaladwa kuti zisawononge pisitoni ndi mphete ya pistoni.
③ Mukatenga gulu la ndodo yolumikizira pisitoni, ndodo yamatabwa imatha kukankhidwira kunja.Gulu la ndodo yolumikizira pisitoni litatulutsidwa, chivundikiro cha ndodo, matailosi ndi bawuti yolumikizira ziyenera kuyikidwa mu situ nthawi yomweyo.
④ Mukachotsa silinda, chokokera cha silinda kapena ndodo yamatabwa iyenera kugwiritsidwa ntchito.Osagunda chingwe cha silinda mwachindunji ndi ndodo yachitsulo.
⑤ Mphete ya pistoni yochotsedwa iyenera kuyikidwa motsatira.Ma cylinder gaskets ndi gaskets zamapepala ayenera kusungidwa bwino.
⑥ Ngati kuli kofunika kuchotsa gudumu la ntchentche, chokokeracho chiyenera kugwiritsidwa ntchito, ndipo mabawuti awiri a chokoka ayenera kupindika mosinthana, ndipo ndikoletsedwa kugwiritsa ntchito nyundo yamanja kumenya mwamphamvu.Mukachotsa flywheel, kuti muteteze flywheel kutayika mwadzidzidzi kugwa, musathamangire kuchotsa mtedza wa flywheel mutatha kumasula.
2. kusamala unsembe
① Zigawo ziyenera kutsukidwa musanayike, fufuzani chilolezo, ndikuwunika mwaukadaulo.Zigawo zomwe sizikukwaniritsa zofunikira zaukadaulo ziyenera kukonzedwa kapena kusinthidwa.
② Dzenje la chipinda cha vortex pamwamba pa pisitoni ndi dzenje la mafuta opaka kumapeto kwa ndodo yolumikizira liyenera kukhala mbali imodzi, ndipo liyenera kukhala pamwamba.
③ Mukasintha chingwe chatsopano cha silinda, silinda iyenera kuyikidwa mu dzenje loyika musanayike mphete yoletsa madzi, yang'anani kutalika kwa thupi loyenda, ndipo ikhoza kukhazikitsidwa mutakwaniritsa zofunikira.Silinda ya injini ya dizilo ya S195 imatha kuzunguliridwa ndi 90 ° ngati kuvala sikuli kwakukulu.Silinda laling'ono la injini ya dizilo S195 silingatembenuzidwe.
④ Mukayika mphete ya pisitoni, samalani kuti musakanda pisitoni ndikuphwanya mphete.Mphete ya chrome-yokutidwa iyenera kuyikidwa mumzere woyamba wa mphete.Ngati nsonga yamkati ya mphete yachiwiri ndi yachitatu ya gasi ili ndi poyambira, mizereyo iyenera kukwezera mmwamba;Ngati m'mphepete mwakunja muli grooves, grooves ayenera kutsika pansi.Chamfer pamphepete mwakunja kwa mphete yamafuta iyenera kukhala yokwera.Mphete ziwiri ndi zitatu za mphete ya pisitoni ya pisitoni zinayi ndi mphete zowoneka bwino, ndipo mbali yokhala ndi "dipatimenti" kapena "┬" pa mpheteyo iyenera kukhala m'mwamba ikayikidwa.Mukayika mphete yamafuta ophatikizika, mpheteyo iyenera kukhazikitsidwa poyamba, ndipo mbali zake ziwiri siziyenera kupindika ndikupindika, kenako ndikuyika mphete yotsatizana, kuti ikanikize kutseguka kwa mphete, kenako ndikuyika mphete ya waveform ndi pamwamba pa mphete ziwiri zafulati.Mukamagwiritsa ntchito mphete zinayi za pisitoni kapena mphete zamafuta ophatikizika, mphete yamafuta iyenera kuyikidwa mumsewu woyamba wamafuta.Gulu lolumikizira ndodo la pisitoni liyenera kuthiridwa ndi mafuta atsopano pamwamba pa pisitoni ndi cylinder liner musanalowe mu silinda.Mukatsegula, kutsegula kwa mphete ya pistoni kuyenera kugwedezeka 120 ° wina ndi mzake, ndipo pewani dzenje lamakono ndi dzenje la piston, pewani malo a pistoni pansi pa kukanikiza mbali.Zida zapadera (zitsulo zachitsulo) ziyenera kugwiritsidwa ntchito pamene mphete ya pistoni yalowetsedwa muzitsulo za silinda.
Pambuyo pakugwiritsa ntchito, mayendedwe akuluakulu akumanzere ndi kumanja saloledwa kusinthidwa, ndipo matailosi a ndodo apamwamba ndi otsika sangathe kuikidwa molakwika.Matailo olumikizira ndodo ayenera kukhala ndi zolimba zina pambuyo pokankhira pampando wa matailosi, ndikukwera pang'ono kuposa ndege yapampando wa matailosi.
6. Mphepete mwa mpukutu wa silinda iyenera kuyang'anizana ndi mutu wa silinda, ndipo mabowo ayenera kugwirizana ndi mabowo a thupi.Mukamangitsa nati wamutu wa silinda, uyenera kumangirizidwa mofanana m'magawo opingasa a diagonal molingana ndi torque yomwe yatchulidwa.Kumasuka kwambiri ndikosavuta kutayikira ndikuwotcha pad silinda;Kuthina kwambiri ndikosavuta kupangitsa kuti cylinder pad iwonongeke, zomwe zimapangitsa kuti bolt kapena screw hole itsetsereka.Bwezerani gasket yatsopano ya silinda, ndikumangitsanso mtedza wa silinda pambuyo pa maola 20.
Zhuo Meng Shanghai Auto Co., Ltd. yadzipereka kugulitsa zida zamagalimoto za MG&MAUXS zolandiridwa kuti mugule.
