Kungani I-Diesel Generator Crankshaft Ablated

Ngesikhathi sokusebenzisa generator diesel , i-crankshaft sliding bearing iyanqanyulwa, eyaziwa ngokuthi "ithayela elivuthayo".Isizathu esiyinhloko salokhu kwehluleka ukuthi lapho umthwalo wemishini kanye nomthwalo oshisayo wenjini kadizili kukhulu kakhulu, futhi ukunikezwa kukawoyela kunganele, ifilimu yamafutha okugcoba ephumelelayo ayikwazi ukwakhiwa phakathi kwejenali ye-crankshaft kanye nesihlahla esithwalayo, okuholela ekuqondeni okuqondile. ukungqubuzana phakathi kwejenali ye-crankshaft kanye nesihlahla esithwalayo.

1. Izimbangela eziqondile zokukhishwa kwe-crankshaft

(1) Izinga likawoyela elingelihle

a.Izinga lamafutha enjini liphansi;uthuli oluningi luxubene emafutheni enjini ngesikhathi sokusetshenziswa isikhathi eside, futhi uwoyela wenjini uyakhishwa nge-oxid futhi wonakaliswe ngenxa yokushisa okuphezulu kokusebenza kwenjini ye-diesel.

b.Kukhona amanzi axutshwe emafutheni enjini.Imifantu ebhantshini lamanzi noma ibhantshi lamanzi inamabhamuza, okuvumela amanzi okupholisa ukuthi angene emafutheni enjini.

c.Amafutha enjini aba mncane.Ngenxa yokuthi amanye amaphampu omjovo kaphethiloli wenjini kadizili asebenzisa ukuthambisa ngomfutho, lapho iphampu yomjovo kaphethiloli kanye nephaseji likawoyela wokugcoba sekuvaliwe ukuze kuhluleke, uwoyela wedizili ungena ephasejini likawoyela wokugcoba ukuze ahlambulule futhi wonakalise uwoyela wokugcoba wenjini kadizili.

(2) Umthamo kawoyela onganele kanye nomfutho ophansi kawoyela

a.Amandla kawoyela awanele.Ukwehluleka ukwengeza uwoyela okwanele ngokusho komthamo oshiwo kuzoholela ekugelezeni kwamafutha okugcoba okwanele enjini ye-diesel, futhi ukwakheka kwefilimu yamafutha okugcoba akukwazi ukuqinisekiswa.

b.Umfutho kawoyela uphansi.Ngenxa yengcindezi kawoyela ephansi, akukho filimu kawoyela wokugcoba okwakhiwa phakathi kwejenali ye-crankshaft kanye nesihlahla esithwalayo.

c.Ngenxa yokungahlanzeki kahle kwamafutha enjini, indawo kawoyela wokuthambisa noma imbobo kawoyela ivinjiwe, noma kukhona uwoyela wenjini onganele noma onganele phakathi kwejenali ye-crankshaft kanye nesihlahla esithwalayo.

(3) Igebe eliphakathi kwejenali ye-crankshaft nesihlahla esithwalayo likhulu kakhulu noma lincane kakhulu.

a.Ukuvunyelwa phakathi kwejenali ye-crankshaft kanye nesihlahla esithwalayo kukhulu kakhulu ukwenza umfutho kawoyela ube phansi futhi akunakwenzeka ukwenza ifilimu yamafutha okugcoba eyanele.

b.Igebe eliphakathi kwejenali ye-crankshaft kanye nesihlahla esithwalayo lincane kakhulu, okuholela ekushuleni kwefilimu kawoyela okwanele noma ukungabikho kwefilimu kawoyela wokugcoba phakathi kwejenali ye-crankshaft kanye nesihlahla esithwalayo.

c.Isihlahla esithwalayo (i-camshaft bushing) sihamba nge-axially.Ngenxa ye-axial displacement yesihlahla esithwalayo (i-camshaft bushing), ukwakheka kwekamelo lokucindezela kwamafutha kubhujiswa, ukucindezela kwamafutha akukwazi ukukhiqizwa, futhi ifilimu yamafutha okugcoba ayikwazi ukwakhiwa.

(4) Ubukhulu bejiyomethri be-crankshaft noma ibhulokhi yesilinda abubekezeleleki.

A. I-crankshaft radial runout (i-crankshaft bending) inkulu kakhulu, kangangokuthi igebe phakathi kwejenali nesihlahla esithwalayo lincane noma alikho igebe, futhi ubukhulu befilimu kawoyela wokuthambisa abanele noma alikho ifilimu kawoyela wokugcoba.

B. Ama-engeli angalingani ejenali ye-crankshaft exhumayo yezinduku nama-engeli angalingani we-crankshaft yokuxhuma amajenali enjini ye-dizili enamasilinda amaningi enza igebe phakathi kwejenali ye-rod yokuxhuma ne-bearing bush libe lincane kakhulu noma lingabibikho igebe, futhi ubukhulu befilimu kawoyela wokuthambisa buyisici. ayanele noma ayikho ifilimu yamafutha okugcoba.

C. Ukubumbana kwembobo yokuthwala eyinhloko yebhulokhi yesilinda kubi kakhulu, okubangela igebe elincane kakhulu noma lingabibikho phakathi kwejenali eyinhloko nesihlahla esithwalayo, ukushuba kwefilimu kawoyela wokugcoba okwanele noma ukungabikho kwefilimu kawoyela wokugcoba.

D.Ukuma kwembobo yesilinda kanye nembobo eyinhloko kubi kakhulu, okwenza ijenali yenduku yokuxhuma kanye nokuvunyelwa kwejenali ye-shaft enkulu kube kuncane kakhulu noma kungabi khona imvume, ukushuba kwefilimu kawoyela wokugcoba okwanele noma kungabibikho ifilimu kawoyela wokuthambisa.

(5) Ukunemba kwebhalansi eguquguqukayo ye-crankshaft, i-flywheel ne-clutch akusabekezeleleki.

Uma ukunemba kwebhalansi okuguquguqukayo kungabekezeleleki, ukuzungezisa ngesivinini esiphezulu kwe-crankshaft kuzodala amandla amaningi angasebenzi, okuzolimaza ukucaciswa phakathi kwejenali ye-crankshaft kanye nesihlahla esithwalayo.Ezimweni ezimbi kakhulu, ijenali kanye nesihlahla esithwalayo kuzogubha ngokuqondile ku-crankshaft futhi kubangele ukukhishwa kwe-crankshaft.

(6) Ukugcinwa ngendlela engafanele.

Ngemuva kokuthi injini ye-diesel isinesikhathi eside isebenza, uma ukunakekelwa okufanele kungenziwanga ngesikhathi, kuzobangela ukuthi i-valve yokunciphisa umfutho wepompo likawoyela, iphampu kawoyela nezinye izingxenye ziguge, zihluleke futhi ziwohloke.Isici sokuhlunga sesihlungi sikawoyela sizovinjwa ukungcola kwamafutha kanye nodaka, okuzonciphisa umfutho kawoyela futhi kubangele ukuphuma kwe-crankshaft.
