Ukuqhaqha iqela lentonga yokudibanisa i-piston
Ukuba imoto yakho imile emanzini, nceda ungayinyanzeli i-ignition, kuba xa amanzi ephezulu kunomoya ongenayo injini, amanzi aya kungena ngqo kwisilinda, enze umxube wamanzi athambileyo, igesi inokucinezelwa, kwaye amanzi akanakucinezelwa. Xa injini ingaphakathi emanzini kwaye i-crankshaft ityhala intonga yokudibanisa ukuze icinezele kwicala lepiston, amanzi awanakucinezelwa. Emva kokuba intonga yokudibanisa iphantsi kokumelana namanzi, iya kuguquka ize igobe, okanye ide iqhekeke.
1. Amanyathelo okuzikhusela xa kuqhekeka
① Uthuli lwangaphandle kufuneka lususwe ngaphambi kokuba luqhekeke, luqwalasele ngononophelo kwaye ukhumbule indawo kunye nophawu lwenxalenye nganye eqhekekileyo.
② Ngaphambi kokuba kukhutshwe intonga yokudibanisa i-piston, inyathelo lekhabhoni kwinxalenye ephezulu ye-cylinder liner kufuneka likhuhlwe ukuze kungalimazi i-piston kunye neringi ye-piston.
③ Xa uthatha iqela lentonga yokudibanisa i-piston, intonga yomthi ingatyhalelwa ngaphandle ngokuthe ngqo. Emva kokuba iqela lentonga yokudibanisa i-piston likhutshiwe, isigqubuthelo sentonga yokudibanisa, ithayile kunye nebholiti yentonga yokudibanisa kufuneka zifakwe kwindawo ngoko nangoko.
④ Xa ususa i-cylinder liner, kufuneka kusetyenziswe i-cylinder liner puller okanye intonga yomthi. Musa ukuyibetha ngqo i-cylinder liner ngentonga yesinyithi.
⑤ Iringi yepiston esusiweyo mayibekwe ngokulandelelana. Iigasket zesilinda kunye neegasket zephepha mazigcinwe kakuhle.
⑥ Ukuba kuyimfuneko ukususa i-flywheel, kufuneka kusetyenziswe i-flywheel puller, kwaye iibholithi ezimbini ze-puller mazijijeke ngokutshintshana, kwaye akuvumelekanga ukusebenzisa isando sesandla ukurhawula ngamandla. Xa ususa i-flywheel, ukuze uthintele ukuba i-flywheel ingawi ngequbuliso, musa ukungxama ukususa i-flywheel nati emva kokuba ikhululekile.
2. Amanyathelo okufaka
① Iindawo mazicocwe phambi kokuba zifakwe, zijongwe ukuba zicocekile na, kwaye kwenziwe uvavanyo lobuchwephesha. Iindawo ezingahlangabezani neemfuno zobugcisa mazilungiswe okanye zitshintshwe.
② Umngxuma wegumbi le-vortex phezulu kwepiston kunye nomngxuma weoyile yokuthambisa kwisiphelo esincinci sentonga yokudibanisa kufuneka ube kwicala elinye, kwaye kufuneka ube phezulu.
③ Xa kutshintshwa i-liner entsha yesilinda, iseti yesilinda kufuneka ifakwe emngxunyeni wokufakela ngaphambi kokufaka iringi yokumelana namanzi, jonga ukuphakama komzimba ophumayo, kwaye ingafakwa ngokusesikweni emva kokuhlangabezana neemfuno. I-liner yesilinda yenjini yedizili ye-S195 ingajikeleziswa ngama-90° ukuba ukuguguleka akubalulekanga. I-liner yesilinda yenjini yedizili ye-S195 ayinakujikwa.
④ Xa ufaka iringi yepiston, lumka ungayikrweli ipiston uze uphule iringi yepiston. Iringi ene-chrome-plated mayifakwe kwi-groove yokuqala yeringi. Ukuba umphetho wangaphakathi weringi yesibini neyesithathu yegesi ine-grooves, imijelo mayifakwe phezulu; Ukuba umphetho wangaphandle une-grooves, imijelo mayifakwe ezantsi. I-chamfer kumphetho wangaphandle weringi yeoyile mayibe phezulu. Imijelo yegesi emibini neyesithathu yeringi yepiston eneeringi ezine yi-conical rings, kwaye icala eline "department" okanye "┬" kwiringi kufuneka libe phezulu xa lifakwa. Xa ufaka iringi yeoyile edibeneyo, iringi ye-lining kufuneka ifakwe kuqala, kwaye iziphelo zayo ezimbini akufuneki zigqubane kwaye zigobe, uze ufake iringi elandelayo ethe tyaba, ukuze icinezele ukuvuleka kweringi ye-lining, uze ufake iringi ye-waveform kunye nemijelo emibini ethe tyaba engentla. Xa usebenzisa imijelo yepiston eneeringi ezine okanye imijelo yeoyile edibeneyo, iringi yeoyile mayifakwe kwi-groove yokuqala yeringi yeoyile. Indibano yentonga yokudibanisa ipiston mayigqunywe ngeoyile entsha kumphezulu wepiston kunye ne-cylinder liner ngaphambi kokuba ingeniswe kwi-cylinder. Xa ulayisha, ukuvulwa kweringi yepiston kufuneka kubekwe ecaleni nge-120° ukusuka kwenye, kwaye kuthintelwe umngxuma we-eddy current kunye nomngxuma wepiston pin, kuthintelwe indawo yepiston phantsi koxinzelelo olusecaleni. Izixhobo ezikhethekileyo (ii-iron clamps) mazisetyenziswe xa iringi yepiston ifakwa kwi-cylinder liner.
Emva kokusetyenziswa, iibheringi eziphambili zasekhohlo nasekunene azivumelekanga ukuba zitshintshwe, kwaye iithayile zentonga yokudibanisa eziphezulu nezisezantsi azinakufakwa ngokuchanekileyo. Ithayile yentonga yokudibanisa kufuneka ibe nokuqina okuthile emva kokucinezela kwisihlalo sethayile, kwaye iphakame kancinci kuneplani yesihlalo sethayile.
6. Umphetho we-roll ye-cylinder pad kufuneka ujonge kwicala lentloko yesilinda, kwaye imingxuma mayihambelane nemingxuma yomzimba. Xa uqinisa i-cylinder head nut, kufuneka iqiniswe ngokulinganayo kwiindawo ezinqamlezileyo ezi-diagonal ngokwe-torque echaziweyo. Ikhululekile kakhulu kulula ukuyivuza kwaye iyitshise i-cylinder pad; Iqinile kakhulu kulula ukwenza i-cylinder pad ilahlekelwe bubuthambile, nto leyo ebangela ukuba i-bolt okanye i-screw hole slip ityibilike. Buyisela i-cylinder gasket entsha, kwaye uyiqinise i-cylinder head nut kwakhona emva kweeyure ezingama-20 zokusebenza.
I-Zhuo Meng Shanghai Auto Co., Ltd. izimisele ukuthengisa iinxalenye zeemoto ze-MG&MAUXS kwaye wamkelekile ukuzithenga.
