I-Assembly of Engine Fasteners for Diesel Generators

1.I-cylinder head nut.Lapho uqinisa i-cylinder head nut, kufanele iqiniswe isinyathelo ngesinyathelo ku-torque eshiwo izikhathi eziningana, futhi uqhubeke ngokuvumelana nesimiso sokuqala phakathi nendawo, bese izinhlangothi ezimbili, kanye nokuwela nge-diagonally.Lapho uqaqa isilinda, kufanele futhi ukhululwe kancane kancane ngendlela enqunyiwe.Uma i-cylinder head nut iqiniswa ngokungalingani noma ingalingani, izokwenza ukuthi indiza yekhanda le-cylinder iguqe futhi ishintshe.Uma nati liqina ngokweqile, ibhawodi lizonwetshwa futhi likhubazeke, futhi umzimba nentambo nakho kuzolimala.Uma inati lingaqiniswa ngokwanele, isilinda sizovuza umoya, amanzi, namafutha, futhi izinga lokushisa eliphezulu legesi kusilinda liyoshisa igesi. i-cylinder gasket .

2. Flywheel nut.Isibonelo, i-flywheel ne-crankshaft yenjini ye-diesel ye-S195 ixhunywe endaweni eqoshiwe kanye nokhiye oyisicaba.Lapho ufaka, i-flywheel nut kumele iqiniswe futhi ikhiywe nge-thrust washer.Uma i-flywheel nut ingaqiniswa ngokuqinile, umsindo oshayayo uzokhishwa lapho injini ye-diesel isebenza.Ezimweni ezimbi kakhulu, izolimaza ikhoni ye-crankshaft, inqume ukhiye, isonte i-crankshaft, futhi ibangele izingozi ezimbi.Qaphela futhi ukuthi amakhona e-thrust washer angagoqwa kanye kuphela.

3. Amabhawodi wezinduku zokuxhuma.Izintambo zokuxhuma ezenziwe ngensimbi yekhwalithi ephezulu zinomthelela omkhulu ngesikhathi somsebenzi, futhi azikwazi ukushintshwa ngamabholithi ajwayelekile.Lapho uqiniswa, i-torque kufanele ifane, futhi amabhawodi enduku amabili axhumayo kufanele aqiniswe kancane kancane ku-torque eshiwo ngokuphenduka okuningana, futhi ekugcineni akhiywe ngocingo lwensimbi.Uma i-torque yokuqinisa ibhawudi yenduku inkulu kakhulu, ibholidi izokwelulwa futhi ikhubazeke noma iphuke, kubangele ingozi ye-cylinder ramming;uma i-torque ye-bolt yokuqinisa induku yokuxhuma incane kakhulu, igebe elithwalayo lizokhula, umsindo oshayayo kanye nomthwalo womthelela uzokwenzeka ngesikhathi somsebenzi, noma kwenzeke Ingozi ye-bushing ephukile kanye nezinduku zokuxhuma.

4. Amabhawodi okuthwala amakhulu.Ukunemba kokufakwa kwe-bearing eyinhloko kufanele kuqinisekiswe ngaphandle kokuxega.Lapho uqinisa ama-bolts athwalayo ayinhloko (okwe-crankshaft yamasilinda amane asekelwe ngokugcwele), ama-bearings angu-5 amakhulu kufanele abe ngokulandelana okuphakathi, bese kuba ngu-2, 4, bese kuba 1, 5, futhi aqinise ngokulinganayo ezingeni elishiwo ku-2. kuze 3 izikhathi.Umzuzwana.Hlola ukuthi ingabe i-crankshaft ijikeleza ngokujwayelekile ngemva kokuqiniswa ngakunye.Izingozi ezibangelwa i-torque eqina ngokweqile noma encane yamabholithi athwalayo ayinhloko ayafana nalawo abangelwa i-torque eqina ngokweqile noma encane yamabholithi enduku yokuxhuma.

5. Balance isisindo bolts.Amabhawodi esisindo sebhalansi kufanele aqiniswe ku-torque eshiwo ngezinyathelo ezimbalwa ngokulandelana.Isisindo sokulinganisa kufanele sifakwe endaweni yokuqala, ngaphandle kwalokho izolahlekelwa umsebenzi wayo webhalansi.

6. I-rocker arm seat nut.Ngenati lengalo ye-rocker, kufanele ihlolwe njalo futhi ihlanganiswe njalo nokugcinwa ngesikhathi sokusetshenziswa.Uma i-rocker arm seat nut ixega, ukuphuma kwe-valve kuzokwanda, ukuvuleka kwe-valve kuzobambezeleka, ukuvalwa kwe-valve kuzothuthukiswa, futhi isikhathi sokuvula i-valve sizofinyezwa, okuzoholela ekungeneni komoya okwanele wenjini ye-diesel, ukuphelelwa amandla. , amandla ancishisiwe, nokwanda kokusetshenziswa kukaphethiloli.

7. Inadi yokukhiya umlomo womjovo kaphethiloli.Lapho ufaka i-fuel injector, i-lock nut yayo kufanele iqiniswe ku-torque ecacisiwe.Ngesikhathi esifanayo, qinisa kabusha izikhathi eziningana, hhayi ngesikhathi esisodwa.Uma inati lokukhiya lomjovo kaphethiloli liqiniswa kakhulu, inati lokukhiya lizokhubazeka futhi ivalvu yenaliti izovimbeka kalula;uma iqiniswe ngokuxekethile, izobangela ukuthi i-injector kaphethiloli ivuze, ukucindezela komjovo kaphethiloli kuzokwehla, futhi i-atomization izoba mbi.Ukwenyuka kokusetshenziswa kukaphethiloli.

8. I-valve yokukhipha uwoyela ihlezi iqinile.Lapho ufaka isihlalo esiqinile sokuhambisa iphampu yomjovo kaphethiloli, kufanele futhi senziwe ngokuya ngetorque eshiwo.Uma isihlalo sevalvu yokukhipha uwoyela siqiniswe ngokweqile, umkhono we-plunger uzokhubazeka, i-plunger izovinjelwa emkhonweni, futhi umhlangano we-plunger uzoguga kusenesikhathi, ukusebenza kokuvala kuzokwehla, futhi amandla azobe enganele;Uma isihlalo esiqinile sixega kakhulu, kuzodala ukuthi ipompo yomjovo kaphethiloli ivuze uwoyela, umfutho kawoyela awukwazi ukutholakala, isikhathi sokunikezwa kukaphethiloli sibambezeleka, kanye nokunikezwa kukaphethiloli kuncipha, okuthinta kakhulu ukusebenza kwenjini.

9. I-injector pressure plate nut.Lapho ufaka i-injector assembly ekhanda le-cylinder lenjini ye-diesel generator diesel , ngaphezu kokukhipha ukungcola okufana ne-carbon deposits esihlalweni sokufaka umhlangano we-injector, ipuleti yokucindezela yomhlangano we-injector akufanele ifakwe ngokuphambene, futhi ubukhulu be-gasket yensimbi kufanele bufanele futhi bungaphuthelwa., Futhi naka i-torque eqinisayo ye-pressure plate nut yomhlangano womjovo.Uma i-torque eqinisayo ye-pressure plate nut inkulu kakhulu, umzimba we-valve we-injector uzokhubazeka, okubangele ukuthi i-injector ibe jam, futhi injini ye-diesel ngeke isebenze;uma i-torque yokuqinisa incane kakhulu, i-injector izovuza umoya, okuholela ekucindezelekeni okunganele kwesilinda kanye nobunzima bokuqalisa injini ye-diesel., Igesi lokushisa eliphezulu lizophinde liphume ngokushesha futhi lishise umjovo kaphethiloli.

Ngaphezu kwalokho, lapho ufaka i-vane rotor eshelelayo yepompo yokusabalalisa kanye namajoyinti epayipi kawoyela anomfutho ophezulu ku-casing yepompo yokusabalalisa, i-torque edingekayo nayo iyenziwa.
