Indima yendandatho yophawu lwe-Camshaft.
Okokuqala, iyini indandatho yokuvala ye-camshaft?
I-camshaft iyingxenye ebaluleke kakhulu yenjini yemoto, iqhuba ukuvulwa nokuvalwa kwevalvu ngokujikeleza kwe-CAM, ukuze ilawule ukungena nokuphuma kwesilinda. Indandatho yokuvala ye-camshaft iyingxenye emise okwendandatho efakwe phakathi kokuphela kwe-camshaft kanye nesembozo segumbi levalvu, evikela uhlelo lwamafutha enjini ikakhulukazi ngokuvimbela ukuvuza kwamafutha enjini.
Okwesibili, iyini indima yendandatho yokuvala ye-camshaft?
Indima yendandatho yokuvala ye-camshaft ibaluleke kakhulu, futhi indima yayo eyinhloko ifaka phakathi izici ezilandelayo:
1. Vimbela ukuvuza kwamafutha: indandatho yokuvala ye-camshaft itholakala phakathi kwe-camshaft kanye nesembozo segumbi le-valve, engavimbela ngempumelelo ukuvuza kwamafutha enjini futhi iqinisekise ukusebenza okuvamile kwenjini.
2. Vimbela uthuli nokungcola ukuthi kungangeni enjinini: indandatho yokuvala i-camshaft ingavimbela ngempumelelo uthuli nokungcola ukuthi kungangeni enjinini ukuqinisekisa ukusebenza okuhlanzekile nokujwayelekile kwenjini.
3. Vikela uhlelo lwamafutha enjini: uphawu lwe-camshaft lungavikela uhlelo lwamafutha enjini ukuze kugwenywe ukuvuza kwamafutha, ngaleyo ndlela kuthuthukiswe impilo yenkonzo kanye nokuthembeka kwenjini.
4. Nciphisa umthelela wokushisa: indandatho yokuvala i-camshaft inganciphisa umthelela wokushisa okuphezulu enjinini, ukuze injini ikwazi ukumelana nokuhlolwa kokushisa okuphezulu ngezinga elithile.
Ezintathu, ukulungiswa kanye nokufakwa esikhundleni kwendandatho yokuvala ye-camshaft
Indandatho yokuvala i-camshaft ivame ukwenziwa ngerabha noma irabha ye-silicone nezinye izinto, ngokukhula kwesikhathi sokusetshenziswa, izobonakala iguga, iqina nezinye izinto, ngaleyo ndlela inciphise ukuvalwa, okuholela ekuvuza kwamafutha nezinye izinkinga. Ngakho-ke, ukuhlolwa njalo kanye nokufakwa esikhundleni kwezimbobo ze-camshaft kungenye yezixhumanisi ezibalulekile zokugcina ukusebenza okuvamile kwenjini.
Isifinyezo se-Iv.
Indandatho yokuvala ye-camshaft iyingxenye ebaluleke kakhulu yenjini yemoto, indima yayo ngokuyinhloko ukuvikela uhlelo lwesekethe kawoyela wenjini, ukuvimbela ukuvuza kukawoyela, kodwa futhi nokuvimbela uthuli nokungcola enjinini. Ukuze kuqinisekiswe ukusebenza okuvamile kwenjini, kuyadingeka ukuhlola nokushintsha indandatho yokuvala ye-camshaft njalo.
Indandatho yokuvala yemoto ye-camshaft iphukile, ukuvuza kukawoyela emotweni kuyini umphumela?
Indandatho yokuvala ye-camshaft yemoto iphukile futhi ukuvuza kukawoyela kunomthelela omkhulu emotweni.
Ukuvuza kwamafutha endandatho yokuvala ye-camshaft kuyinkinga okudingeka inakwe. Okokuqala, ukuvuza kwamafutha kuzoholela ekugcotshweni kabi kwenjini, bese kusheshisa ukuguguleka, kungase kuholele ngisho nemiphumela emibi njengokubamba umgodi kanye nethayela. Lokhu akugcini nje ngokuphazamisa ukusebenza okuvamile kwenjini, kungase futhi kube yingozi ekuphepheni kokushayela. Okwesibili, ukuvuza kwamafutha kulula ukunciphisa uwoyela, kuholela ekuqongeleleni kwamafutha amaningi ebhodini lokuvikela injini, akugcini nje ngokwandisa umthwalo wenjini, kungabangela nezinkinga ezinkulu njengokushiswa kwamathayela, ukudonsa isilinda. Ngaphezu kwalokho, uma ukuvuza kwamafutha kukubi kakhulu, uwoyela osebhokisini uzophela maduze, kungaholela ekulimaleni kwamabhere, ukuguguleka kwegiya, ngisho nasesikhaleni segiya.
Ngakho-ke, uma ukuvuza kukawoyela we-camshaft seal sekutholiwe, kufanele uye esitolo sokulungisa ochwepheshe ngokushesha ukuze kuhlolwe futhi kulungiswe. Nakuba ukuchitheka kukawoyela okuncane kungase kungabangela izinkinga ezisheshayo ukuchitheka kukawoyela okukhulu kumele kulungiswe ngesikhathi ukuze kugwenywe ukulimaza injini. Ngesikhathi esifanayo, ukuze kugwenywe ukubhebhetheka kwesimo sokuvuza kukawoyela, kutuswa ukugwema ukushayela ngesivinini esikhulu isikhathi eside, ukusheshisa okusheshayo, ukubhuleka okungazelelwe kanye nokunye ukuziphatha okunolaka, ukuze kuncishiswe umthwalo nokuguguleka kwenjini.
Uma ufuna ukwazi okwengeziwe, qhubeka ufunda ezinye izihloko ezikulesi siza!
Sicela usishayele ucingo uma udinga imikhiqizo enjalo.
I-Zhuo Meng Shanghai Auto Co., Ltd. izibophezele ekuthengiseni izingxenye zezimoto ze-MG&MAUXS futhi wamukelekile ukuzithenga.
