Assembly of Engine Fasteners for Diesel Generators

1.Mtedza wamutu wa silinda.Mukamangitsa nati wamutu wa silinda, uyenera kumangirizidwa pang'onopang'ono ku torque yotchulidwa kangapo, ndikupitilira molingana ndi mfundo yoyamba pakati, kenako mbali ziwiri, ndikuwoloka diagonally.Pochotsa silindayo, iyeneranso kumasulidwa pang'onopang'ono mu dongosolo lolembedwa.Ngati nati wamutu wa silindayo waumitsidwa mosagwirizana kapena mosagwirizana, zipangitsa kuti ndege yamutu wa silinda ikhale yopindika ndi kupunduka.Mtedzawo ukathithikana kwambiri, bawutiyo imatambasulidwa ndi kupunduka, ndipo thupi ndi ulusi zidzawonongekanso.Ngati mtedzawo sunawumitsidwe mokwanira, silinda imataya mpweya, madzi, ndi mafuta, ndipo mpweya wotentha kwambiri mu silinda udzawotcha. cylinder gasket .

2. Mtedza wa Flywheel.Mwachitsanzo, flywheel ndi crankshaft injini dizilo S195 olumikizidwa kwa pamwamba tapered ndi kiyi lathyathyathya.Mukayika, mtedza wa flywheel uyenera kumangidwa ndikutsekedwa ndi thrust washer.Ngati mtedza wa flywheel sunawunikidwe mwamphamvu, phokoso logogoda lidzapangidwa pamene injini ya dizilo ikugwira ntchito.Zikavuta kwambiri, zimatha kuwononga kondomu ya crankshaft, kudula makiyi, kupotoza chikwapu, ndikuyambitsa ngozi zazikulu.Dziwaninso kuti ngodya za thrust washer zitha kupindidwa kamodzi.

3. Kulumikiza ndodo mabawuti.Maboti olumikizira opangidwa ndi zitsulo zapamwamba amakhala ndi mphamvu yayikulu panthawi yantchito, ndipo sangathe kusinthidwa ndi mabawuti wamba.Mukalimbitsa, torque iyenera kukhala yofanana, ndipo zomangira ziwiri zolumikizira ziyenera kumangika pang'onopang'ono ku torque yomwe yatchulidwa mosinthana kangapo, ndipo pamapeto pake kutsekedwa ndi waya wachitsulo.Ngati cholumikizira cholumikizira bawuti ndi chachikulu kwambiri, bawutiyo imatambasulidwa ndikupunduka kapena kusweka, kuchititsa ngozi ya silinda;ngati cholumikizira cholumikizira bawuti chomangitsa torque ndi chocheperako, kusiyana kumawonjezeka, kugogoda kwa phokoso ndi kukhudzidwa kudzachitika panthawi ya ntchito, kapena ngakhale kuchitika Ngozi yosweka ndi mabawuti olumikizira ndodo.

4. Mabawuti akuluakulu.Kuyika kolondola kwa chigawo chachikulu kuyenera kutsimikiziridwa popanda kutayikira.Mukamangitsa mabawuti akulu (kwa crankshaft yothandizidwa kwathunthu ndi ma silinda anayi), ma bere 5 akulu ayenera kukhala mu dongosolo lapakati, kenako 2, 4, kenako 1, 5, ndikumangirira molingana mpaka mulingo womwe wafotokozedwa mu 2. ku 3x.Mphindi.Yang'anani ngati crankshaft imazungulira bwino mukangolimbitsa.Zowopsa zomwe zimayambitsidwa ndi torque yayikulu kapena yaying'ono yomangirira ma bolts akuluakulu amakhala ofanana ndi omwe amayambitsidwa ndi torque yayikulu kapena yaying'ono yomangirira ma bawuti olumikizira ndodo.

5. Kulinganiza mabawuti olemetsa.Mabawuti olemetsa ayenera kumangika ku torque yomwe yatchulidwa m'magawo angapo motsatizana.Kulemera kwapakati kuyenera kukhazikitsidwa pamalo oyamba, apo ayi kudzataya ntchito yake.

6. Mpando wa mtedza wa rocker arm.Kwa mtedza wa rocker arm, uyenera kuwunikiridwa pafupipafupi komanso kuphatikiza nthawi zonse ndikuwukonza pakagwiritsidwa ntchito.Ngati mtedza wa rocker arm seat utayikira, chilolezo cha valve chidzawonjezeka, kutsegula kwa valve kudzachedwa, kutsekedwa kwa valve kudzakhala kopita patsogolo, ndipo nthawi yotsegulira valve idzafupikitsidwa, zomwe zimapangitsa kuti injini ya dizilo ikhale yosakwanira, kutulutsa mpweya wosakwanira. , kuchepa kwa mphamvu, ndi kuchuluka kwa mafuta.

7. The mafuta jakisoni nozzle loko nati.Mukayika jekeseni wamafuta, nati yake yotsekera iyenera kumangirizidwa ku torque yomwe yatchulidwa.Panthawi imodzimodziyo, limbitsaninso kangapo, osati nthawi imodzi.Ngati loko nati ya jekeseni wamafuta imangiriridwa mwamphamvu kwambiri, nati ya loko imapunduka ndipo valavu ya singano imatsekeka mosavuta;ngati itayimitsidwa momasuka, imapangitsa kuti jekeseni wamafuta atayike, kuthamanga kwa jekeseni wamafuta kumatsika, ndipo atomization idzakhala yosauka.Kuchuluka kwamafuta.

8. Vavu yotulutsa mafuta imakhala yolimba.Mukakhazikitsa valavu yoperekera pampu yamafuta, iyeneranso kuchitidwa molingana ndi torque yomwe yatchulidwa.Ngati mpando wa valve wotulutsa mafuta wakhazikika mopitilira muyeso, mkono wa plunger udzakhala wopunduka, plunger idzatsekedwa m'manja, ndipo gulu la plunger lidzatha msanga, ntchito yosindikiza idzachepa, ndipo mphamvu sizikhala zokwanira;Ngati mpando wothina umakhala wotayirira kwambiri, zipangitsa kuti pampu yojambulira mafuta itsike mafuta, kukakamiza kwamafuta sikungakhazikitsidwe, nthawi yoperekera mafuta ikucheperachepera, komanso kuchuluka kwamafuta kumachepetsedwa, zomwe zimakhudza kwambiri magwiridwe antchito a injini.

9. Injector kuthamanga mbale mtedza.Pamene khazikitsa msonkhano jekeseni pa yamphamvu mutu wa injini dizilo jenereta ya dizilo , kuwonjezera pa kuchotsa dothi monga ma carbon deposits mu mpando wopangira jekeseni wa jekeseni, mbale yoponderezedwa ya msonkhano wa jekeseni sayenera kuikidwa mobwerezabwereza, ndipo makulidwe a gasket zitsulo ayenera kukhala oyenera komanso osasowa., Komanso tcherani khutu kumangirira makokedwe a nati woponderezedwa wa mbale ya jekeseni.Ngati makokedwe omangirira a nati woponderezedwa ndi wamkulu kwambiri, thupi la valavu la jekeseni lidzakhala lopunduka, zomwe zimapangitsa kuti jekeseniyo ikhale yodzaza, ndipo injini ya dizilo sigwira ntchito;ngati torque yomangirira ndi yaying'ono kwambiri, jekeseniyo imataya mpweya, zomwe zimapangitsa kuti pakhale kuthamanga kwa silinda kosakwanira komanso kuvutikira kuyambitsa injini ya dizilo., Gasi wotentha kwambiri adzathamangiranso ndikuwotcha jekeseni wamafuta.

Kuphatikiza apo, pakuyika chowongolera chowongolera chapampu yogawa ndi mapope amafuta othamanga kwambiri pamapaipi ogawa, torque yofunikira imachitikanso.
