Ukuhlakazwa kweqembu lenduku yokuxhuma i-piston
Uma imoto yakho imile emanzini, sicela ungaphoqi ukuthungela, ngoba lapho amanzi engaphezulu kokungenisa umoya wenjini, amanzi azongena ngqo kusilinda, enze ingxube yamanzi athambile, igesi ingacindezelwa, namanzi. ayikwazi ukucindezelwa. Lapho injini isemanzini futhi i-crankshaft isunduza induku yokuxhuma ukuze iminyanise ibheke episton, amanzi awakwazi ukucindezelwa. Ngemuva kokuthi induku yokuxhuma ibhekene nokumelana kwamanzi, izokhubaza futhi igobe, noma iphule.
1. Izinyathelo zokuqapha zokuqaqa
① Uthuli lwangaphandle kufanele lususwe ngaphambi kokuhlakazwa, qaphela ngokucophelela futhi ukhumbule indawo nomaka wengxenye ngayinye ehlakaziwe.
② Ngaphambi kokukhipha induku yokuxhuma ipiston, isitebhisi sekhabhoni engxenyeni engenhla yesilinda liner kufanele sicijwe ukugwema ukulimaza ipiston neringi.
③ Uma uthatha iqembu lenduku yokuxhuma i-piston, induku yokhuni ingaphushelwa ngaphandle. Ngemuva kokuthi iqembu lenduku yokuxhuma i-piston likhishwe, isembozo senduku yokuxhuma, i-tile kanye ne-bolt yenduku yokuxhuma kufanele ifakwe endaweni ngokushesha.
④ Uma ukhipha i-cylinder liner, i-cylinder liner puller noma induku yokhuni kufanele isetshenziswe. Ungashayi i-cylinder liner ngqo ngentonga yensimbi.
⑤ Indandatho yepiston ekhishiwe kufanele ibekwe ngokulandelana. Ama-cylinder gaskets nama-gaskets wephepha kufanele agcinwe kahle.
⑥ Uma kudingekile ukususa i-flywheel, i-flywheel puller kufanele isetshenziswe, futhi amabhawodi amabili esidonsayo kufanele asontwe ngokushintshana, futhi kwenqatshelwe ngokuphelele ukusebenzisa isando sesandla ukuze ushaye kakhulu isando. Lapho ususa i-flywheel, ukuze uvimbele ukulimala kokuwa ngokuzumayo kwe-flywheel, ungasheshi ukususa i-flywheel nut ngemuva kokukhululeka.
2. Izinyathelo zokuphepha zokufakwa
① Izingxenye kufanele zihlanzwe ngaphambi kokufakwa, uhlole imvume, futhi wenze ukuhlolwa kobuchwepheshe. Izingxenye ezingahlangabezani nezidingo zobuchwepheshe kufanele zilungiswe noma zishintshwe.
② Umgodi wegumbi le-vortex phezulu kwepiston kanye nembobo yamafutha okugcoba ekugcineni okuncane kwenduku yokuxhuma kufanele kube ohlangothini olufanayo, futhi kufanele kube phezulu.
③ Uma ushintsha umugqa omusha wesilinda, isethi yesilinda kufanele ifakwe embotsheni yokufaka ngaphambi kokufaka iringi yokumelana namanzi, hlola ubude bomzimba oqhuqhayo, futhi ingafakwa ngokusemthethweni ngemva kokuhlangabezana nezidingo. I-cylinder liner yenjini kadizili i-S195 ingazungeziswa ngo-90° uma ukuguga kungekukhulu. I-cylinder liner ye-S195 injini ye-diesel ayikwazi ukushintshwa.
④ Uma ufaka iringi yepiston, qaphela ukuthi ungaklwebhi ipiston bese uphula iringi yepiston. Iringi ye-chrome-plated izofakwa ku-ring groove yokuqala. Uma unqenqema lwangaphakathi lwendandatho yegesi yesibili neyesithathu lunemifantu, imifantu kufanele yenziwe phezulu; Uma unqenqema lwangaphandle lunemifantu, ama-grooves kufanele enziwe abheke phansi. I-chamfer emaphethelweni angaphandle endandatho yamafutha kufanele ibe phezulu. Izindandatho zegesi ezimbili nezintathu zendandatho yephiston enezindandatho ezine zingama-conical, futhi uhlangothi oluno "department" noma "┬" eringini kufanele lube phezulu uma lufakiwe. Lapho ufaka indandatho kawoyela ehlanganisiwe, indandatho yocingo kufanele ifakwe kuqala, futhi iziphetho zayo ezimbili akufanele zidlulele futhi zigobe, bese ifaka indandatho elandelayo eyisicaba, ukuze icindezele ukuvulwa kwendandatho yomugqa, bese ifaka indandatho ye-waveform kanye ngaphezu kwamasongo amabili ayisicaba. Uma usebenzisa izindandatho ezine-ring piston noma izindandatho zikawoyela ezihlanganisiwe, indandatho kawoyela kufanele ilayishwe endaweni yokuqala kawoyela eyindandatho. Umhlangano wenduku yokuxhuma i-piston kufanele ugcotshwe ngamafutha amasha ebusweni be-piston kanye ne-cylinder liner ngaphambi kokulayisha ku-cylinder. Lapho ulayisha, ukuvulwa kweringi yepiston kufanele kugxambuke ngo-120° ukusuka komunye nomunye, futhi ugweme umgodi wamanje we-eddy kanye nembobo yephinikhodi ye-piston, gwema indawo yepiston ngaphansi kwengcindezi eseceleni. Amathuluzi akhethekile (izinsimbi zensimbi) kufanele zisetshenziswe lapho indandatho yepiston ilayishwa ku-cylinder liner.
Ngemuva kokusetshenziswa, ama-bearings ayinhloko angakwesokunxele nangakwesokudla awavunyelwe ukushintshwa, futhi amathayili wenduku yokuxhuma engenhla nangaphansi ayikwazi ukufakwa ngokungalungile. Ithayela lenduku yokuxhuma kufanele libe nokuqina okuthile ngemva kokucindezela esihlalweni sethayela, futhi libe phezulu kancane kunendiza yesihlalo sethayela.
6. I-roll edge ye-cylinder pad kufanele ibhekane nohlangothi lwekhanda le-cylinder, futhi imigodi kufanele ihambisane nezimbobo zomzimba. Lapho uqinisa nati lekhanda le-cylinder, kufanele liqiniswe ngokulinganayo ezingxenyeni eziphambano ze-diagonal ngokusho kwe-torque ecacisiwe. Ukuxega kakhulu kulula ukuvuza futhi kushise i-cylinder pad; Ukuqina kakhulu kulula ukwenza iphedi yesilinda ilahlekelwe ukunwebeka, okuholela ekusheleleni kwe-bolt noma i-screw hole. Faka esikhundleni isilinda gasket esisha, bese uqinisa nathi lekhanda lesilinda futhi ngemva kwamahora angu-20 wokusebenza.
UZhuo Meng Shanghai Auto Co., Ltd. uzibophezele ekuthengiseni izingxenye zezimoto ze-MG&MAUXS wamukelekile ukuzithenga.
