Ukuhlukaniswa kweqembu lenduku yokuxhuma i-piston
Uma imoto yakho imile emanzini, sicela ungayiphoqi ukuthungela, ngoba uma amanzi ephakeme kunomoya wenjini, amanzi azongena ngqo kwisilinda, akhe ingxube yamanzi athambile, igesi ingacindezelwa, futhi amanzi awakwazi ukucindezelwa. Uma injini isemanzini futhi i-crankshaft isunduza induku yokuxhuma ukuze icindezelwe ibheke episton, amanzi awakwazi ukucindezelwa. Ngemva kokuba induku yokuxhuma ibhekene nokumelana kwamanzi, izoshintsha isimo futhi igobe, noma iphuke.
1. Izinyathelo zokuphepha zokuqaqa
① Uthuli lwangaphandle kufanele lususwe ngaphambi kokuhlakazwa, luqaphelisise futhi lukhumbule indawo kanye nophawu lwengxenye ngayinye ehlakaziwe.
② Ngaphambi kokukhipha induku yokuxhuma ye-piston, isinyathelo sekhabhoni engxenyeni engenhla ye-cylinder liner kumele siklwebhe ukuze kugwenywe ukulimaza i-piston kanye nendandatho ye-piston.
③ Uma uthatha iqembu lenduku yokuxhuma ye-piston, induku yokhuni ingacindezelwa ngqo ngaphandle. Ngemva kokuba iqembu lenduku yokuxhuma ye-piston selikhishwe, isembozo senduku yokuxhuma, ithayela kanye nebhawodi yenduku yokuxhuma kufanele kufakwe endaweni ngokushesha.
④ Uma ususa i-cylinder liner, kufanele kusetshenziswe i-cylinder liner puller noma induku yokhuni. Ungashayi i-cylinder liner ngqo ngenduku yensimbi.
⑤ Indandatho yepiston esusiwe kufanele ibekwe ngokulandelana. Ama-gasket esilinda kanye nama-gasket ephepha kufanele agcinwe kahle.
⑥ Uma kudingeka ukususa isondo eliyindilinga, kufanele kusetshenziswe i-puller yesondo eliyindilinga, futhi amabhawodi amabili e-puller kufanele ajikelezwe ngokushintshana, futhi akuvunyelwe ngokuphelele ukusebenzisa isando sesandla ukuze ushaye ngamandla. Lapho ususa isondo eliyindilinga, ukuze uvimbele ukulimala kwesondo eliyindilinga ngokuzumayo, ungasheshi ukususa inathi lesondo eliyindilinga ngemva kokulikhulula.
2. Izinyathelo zokufaka
① Izingxenye kumele zihlanzwe ngaphambi kokufakwa, kuhlolwe indawo evulekile, bese kwenziwa ukuhlolwa kobuchwepheshe. Izingxenye ezingahlangabezani nezidingo zobuchwepheshe kumele zilungiswe noma zishintshwe.
② Umgodi wegumbi le-vortex phezulu kwe-piston kanye nomgodi kawoyela wokugcoba ekugcineni okuncane kwenduku yokuxhuma kufanele kube ohlangothini olufanayo, futhi kumele kube phezulu.
③ Uma ushintsha i-liner entsha yesilinda, isethi yesilinda kufanele ifakwe emgodini wokufaka ngaphambi kokufaka indandatho yokumelana namanzi, hlola ukuphakama komzimba ovundlile, futhi ingafakwa ngokusemthethweni ngemuva kokuhlangabezana nezidingo. I-liner yesilinda yenjini yedizili ye-S195 ingajikeleziswa ngo-90° uma ukuguguleka kungekukhulu. I-liner yesilinda yenjini yedizili ye-S195 ayikwazi ukuphendulwa.
④ Uma ufaka indandatho yepiston, qaphela ukuthi ungayiklwebhi i-piston bese uphula indandatho yepiston. Indandatho efakwe i-chrome kufanele ifakwe emgodini wokuqala wendandatho. Uma unqenqema lwangaphakathi lwendandatho yesibili neyesithathu yegesi inemifantu, imifantu kufanele yenziwe phezulu; Uma unqenqema lwangaphandle lunemifantu, imifantu kufanele yenziwe phansi. I-chamfer enqenqemeni langaphandle lendandatho kawoyela kufanele ibe phezulu. Amasongo amabili namathathu egesi endandatho yepiston enezindandatho ezine ayizindandatho eziyindilinga, kanti uhlangothi olune "department" noma "┬" endandatho kufanele lube phezulu uma lufakwa. Uma ufaka indandatho kawoyela ehlanganisiwe, indandatho ye-lining kufanele ifakwe kuqala, futhi iziphetho zayo ezimbili akufanele zihlangane futhi zigobe, bese ufaka indandatho elandelayo eyisicaba, ukuze icindezele ukuvuleka kwendandatho ye-lining, bese ufaka indandatho ye-waveform kanye namasongo amabili ayisicaba angenhla. Uma usebenzisa amasongo episton anezindandatho ezine noma amasongo kawoyela ahlanganisiwe, indandatho kawoyela kufanele ilayishwe emgodini wokuqala wendandatho kawoyela. Inhlangano yenduku yokuxhuma yepiston kufanele igcotshwe ngamafutha amasha ebusweni bepiston kanye ne-cylinder liner ngaphambi kokufaka ku-cylinder. Uma ulayisha, ukuvuleka kwendandatho yepiston kufanele kubekwe eceleni ngo-120° komunye nomunye, futhi ugweme umgodi wamanje we-eddy kanye nomgodi wephini lepiston, ugweme indawo yepiston ngaphansi kwengcindezi eseceleni. Amathuluzi akhethekile (ama-clamp ensimbi) kufanele asetshenziswe lapho indandatho yepiston ilayishwa ku-cylinder liner.
Ngemva kokusetshenziswa, amabheringi amakhulu kwesobunxele nakwesokudla awavunyelwe ukushintshwa, futhi amathayili enduku yokuxhuma ephezulu nengezansi awakwazi ukufakwa ngendlela engafanele. Ithayili lenduku yokuxhuma kufanele libe nokuqina okuthile ngemva kokucindezela esihlalweni sethayili, futhi liphakame kancane kunesihlalo sethayili.
6. Unqenqema lwephedi yesilinda kufanele lubheke ohlangothini lwekhanda lesilinda, futhi imigodi kufanele iqondaniswe nemigodi yomzimba. Uma uqinisa i-nut yekhanda lesilinda, kufanele iqiniswe ngokulinganayo ngezigaba ezivundlile ngokwe-torque echaziwe. Ikhululekile kakhulu kulula ukuyivuza futhi iyishise iphedi yesilinda; Iqine kakhulu kulula ukwenza iphedi yesilinda ilahlekelwe ukuqina, okuholela ekusheleleni kwembobo noma imbobo yezikulufo. Shintsha i-gasket yesilinda entsha, bese uqinisa i-nut yekhanda lesilinda futhi ngemva kwamahora angama-20 yokusebenza.
I-Zhuo Meng Shanghai Auto Co., Ltd. izibophezele ekuthengiseni izingxenye zezimoto ze-MG&MAUXS futhi wamukelekile ukuzithenga.
