Kuchotsa gulu la ndodo yolumikizira pisitoni
Ngati galimoto yanu yaima m'madzi, chonde musakakamize kuyatsa, chifukwa madzi akakhala okwera kuposa mpweya womwe injini imatenga, madziwo amalowa mwachindunji mu silinda, ndikupanga madzi ofewa, mpweyawo ukhoza kukakamizidwa, ndipo madziwo sangakanikizidwe. Injini ikalowa m'madzi ndipo crankshaft ikankhira ndodo yolumikizira kuti ikanikize molunjika ku pistoni, madziwo sangakanikizidwe. Ndodo yolumikizira ikagonjetsedwa ndi madzi, imapindika ndikupindika, kapena kusweka.
1. Malangizo opewera kusokoneza
① Fumbi lakunja liyenera kuchotsedwa musanalichotse, yang'anirani mosamala ndikukumbukira malo ndi chizindikiro cha gawo lililonse lochotsedwa.
② Musanachotse ndodo yolumikizira pistoni, sitepe ya kaboni pamwamba pa silinda iyenera kukwezedwa kuti isawononge pistoni ndi mphete ya pistoni.
③ Mukatenga gulu la ndodo yolumikizira pistoni, ndodo yamatabwa ikhoza kukankhidwira kunja mwachindunji. Gulu la ndodo yolumikizira pistoni litatulutsidwa, chivundikiro cha ndodo yolumikizira, matailosi ndi botolo la ndodo yolumikizira ziyenera kuyikidwa pamalopo nthawi yomweyo.
④ Mukachotsa chogwirira cha silinda, chogwirira cha silinda kapena ndodo yamatabwa ziyenera kugwiritsidwa ntchito. Musagunde chogwirira cha silinda mwachindunji ndi ndodo yachitsulo.
⑤ Mphete ya pistoni yochotsedwa iyenera kuyikidwa motsatizana. Ma gasket a silinda ndi ma gasket a pepala ziyenera kusungidwa bwino.
⑥ Ngati pakufunika kuchotsa flywheel, chokokera cha flywheel chiyenera kugwiritsidwa ntchito, ndipo mabotolo awiri a chokokeracho ayenera kupotozedwa motsatizana, ndipo ndikoletsedwa kugwiritsa ntchito nyundo yamanja kuti mumenye mwamphamvu. Mukachotsa flywheel, kuti mupewe kuvulala mwadzidzidzi kwa flywheel, musafulumire kuchotsa nati ya flywheel mutamasula.
2. Malangizo okhazikitsa
① Zigawo ziyenera kutsukidwa musanaziike, kuyang'ana malo otseguka, ndikuchita kuwunika kwaukadaulo. Zigawo zomwe sizikukwaniritsa zofunikira zaukadaulo ziyenera kukonzedwa kapena kusinthidwa.
② Dzenje la chipinda cha vortex pamwamba pa pistoni ndi dzenje la mafuta odzola kumapeto kwa ndodo yolumikizira ziyenera kukhala mbali yomweyo, ndipo ziyenera kukhala mmwamba.
③ Mukasintha choyikapo chatsopano cha silinda, choyikapo cha silinda chiyenera kuyikidwa mu dzenje loyikira musanayike mphete yolimbana ndi madzi, yang'anani kutalika kwa thupi lozungulira, ndipo chikhoza kuyikidwa mwalamulo mutakwaniritsa zofunikira. Choyikapo cha silinda cha injini ya dizilo ya S195 chikhoza kuzunguliridwa 90° ngati kuwonongeka si kwakukulu. Choyikapo cha silinda cha injini ya dizilo ya S195 sichingazunguliridwe.
④ Mukayika mphete ya piston, samalani kuti musakanda piston ndikuswa mphete ya piston. Mphete yophimbidwa ndi chrome iyenera kuyikidwa mu groove yoyamba ya mphete. Ngati m'mphepete mwa mphete yachiwiri ndi yachitatu ya gasi muli mipata, mipata iyenera kupangidwa mmwamba; Ngati m'mphepete mwakunja muli mipata, mipata iyenera kupangidwa pansi. Chamfer yomwe ili m'mphepete mwakunja kwa mphete ya mafuta iyenera kukhala mmwamba. Mphete ziwiri ndi zitatu za gasi za mphete ya piston ya mphete zinayi ndi mphete zozungulira, ndipo mbali yokhala ndi "dipatimenti" kapena "┬" pa mphete iyenera kukhala mmwamba ikayikidwa. Mukayika mphete yamafuta yophatikizana, mphete yamkati iyenera kuyikidwa kaye, ndipo malekezero ake awiri sayenera kugwerana ndikupindika, kenako ikani mphete yotsatira yathyathyathya, kuti ikanikizire kutsegula kwa mphete yamkati, kenako ikani mphete ya waveform ndi mphete ziwiri zathyathyathya zomwe zili pamwambapa. Mukagwiritsa ntchito mphete za piston ya mphete zinayi kapena mphete zamafuta zophatikizana, mphete yamafuta iyenera kuyikidwa mu groove yoyamba ya mphete yamafuta. Cholumikizira ndodo ya piston chiyenera kupakidwa ndi mafuta atsopano pamwamba pa piston ndi silinda liner musanayike mu silinda. Mukatsegula, kutsegula kwa mphete ya pistoni kuyenera kuzunguliridwa 120° kuchokera kwa wina ndi mnzake, ndipo pewani dzenje la eddy current ndi dzenje la pistoni, pewani malo a pistoni pansi pa kupanikizika kwa mbali. Zida zapadera (zomangira zitsulo) ziyenera kugwiritsidwa ntchito mphete ya pistoni ikalowetsedwa mu silinda.
Mukatha kugwiritsa ntchito, mabearing akuluakulu akumanzere ndi kumanja saloledwa kusinthidwa, ndipo matailosi a ndodo yolumikizira apamwamba ndi apansi sangaikidwe molakwika. Matailosi a ndodo yolumikizira ayenera kukhala olimba pang'ono akakanikiza pampando wa matailosi, komanso okwera pang'ono kuposa malo a mpando wa matailosi.
6. Mphepete mwa silinda iyenera kuyang'ana mbali ya mutu wa silinda, ndipo mabowo ayenera kugwirizana ndi mabowo a thupi. Mukamangirira nati ya mutu wa silinda, iyenera kumangidwa mofanana m'magawo opingasa molingana ndi mphamvu yomwe yaperekedwa. Yomasuka kwambiri ndi yosavuta kutulutsa ndikuwotcha silinda; Yolimba kwambiri ndi yosavuta kupangitsa silinda kutaya kulimba, zomwe zimapangitsa kuti bolt kapena screw hole igwe. Sinthani gasket yatsopano ya silinda, ndikumanga nati ya mutu wa silinda kamodzinso patatha maola 20 ikugwira ntchito.
Zhuo Meng Shanghai Auto Co., Ltd. yadzipereka kugulitsa zida zamagalimoto za MG&MAUXS zomwe zikulandiridwa kugula.
