Amaphutha Avamile kanye Nezixazululo Zesistimu Yamafutha Yesethi Ye-Generator

Uhlelo lukaphethiloli lwesethi yejeneretha yedizili luyingxenye eyinhloko.Ngaphezu kokuguga kwangaphambi kwesikhathi kwezingxenye ezintathu ezihlanganisa ukunemba zesistimu kaphethiloli, okuholela ekwehlisweni kwamandla ejeneretha, ukwanda kokusetshenziswa kukaphethiloli kanye nentuthu ekhipha umoya, kunezinhlobo ezimbili zamaphutha okungenzeka kakhulu zenzeke ohlelweni lukaphethiloli: eyodwa. iphutha elibangelwa ukufakwa okungafanele kwephampu yomjovo kaphethiloli, kanti elinye iphutha elisetshenziswayo.

A.Ukwehluleka okudalwe ukufakwa ngendlela engafanele kwephampu yomjovo kaphethiloli we isethi ye-diesel generator

1. Ukhiye we-semicircular awufakiwe endaweni

Ngephampu yomjovo kaphethiloli exhunywe nge-flange, lapho indawo yokufaka ukhiye we-semicircular phakathi kwegiya lesikhathi lokunikezwa kukaphethiloli kanye nesilawuli esizenzakalelayo se-angle yokuphakela uphethiloli kusengaphambili kanye nekhamera yepompo yomjovo kaphethiloli ingalungile, kuzoba nokungahambi kahle kwesikhathi sokunikezwa kukaphethiloli. , ukuqala kwenjini okunzima, intuthu kanye nokushisa kwamanzi okuphezulu.Uma ingakwazi ukulungiswa ngembobo ye-arc ku-flange, iphampu yomjovo kaphethiloli idinga ukukhishwa futhi ifakwe kabusha.Ngemuva kokususwa, ukuhlehlisa okusobala kungabonwa kukhiye we-semicircular.

2. I-oil inlet kanye nezikulufu zokubuya zifakwe ngokungalungile

Lapho uxhuma ipayipi likawoyela, uma isikulufu sokubuyisela uwoyela sifakwe ngokungalungile endaweni ehlangene yepayipi yokufaka uwoyela yephampu yomjovo kaphethiloli, ngenxa yesenzo se-valve yokuhlola esikulukweni sokubuyisela uwoyela, uphethiloli awukwazi ukungena noma kungena inani elincane kuphela. i-oil inlet chamber yepompo yomjovo we-fuel, ukuze isethi ye-generator diesel ayikwazi ukuqaliswa noma ayikwazi ukufakwa i-refueled ngemva kokuqala ukwandisa isivinini.Ngalesi sikhathi, iphampu yesandla inokumelana okukhulu nokupompa uwoyela, futhi ayikwazi ngisho nokucindezela iphampu yesandla.Ngalesi sikhathi, iphutha lingaqedwa inqobo nje uma izikhundla zokufakwa kwe-oyili yokungena nezikulufu zokubuyisela zishintshaniswa.

B. Amaphutha avamile ekusebenziseni isethi yejeneretha yedizili

1. Ukunikezwa kawoyela okungekuhle kwesekethe yamafutha anengcindezi ephansi

Amapayipi okungenisa uwoyela namapayipi abuyayo ejeneretha kadizili asethwe esuka ethangini likawoyela eya endaweni yokufaka uwoyela yepompo yomjovo kawoyela ayingxenye yesekethe kawoyela enengcindezi ephansi.Lapho ipayipi elihlangene, i-gasket kanye nepayipi likawoyela livuza ngenxa yomonakalo, umoya uzongena kumjikelezo kawoyela ukuze ukhiqize ukumelana komoya, okuholela ekungabini kahle kukawoyela, ukuqala kanzima kwenjini, ukusheshisa kancane kanye namanye amaphutha, futhi kuzovala ngokuzenzakalelayo kubucayi obukhulu. amacala.Lapho indawo ephambanayo yepayipi likawoyela incishisiwe ngenxa yokuguga, ukuwohloka nokuvinjwa kokungcola, noma isikrini sokuhlunga uwoyela kanye nesici sokuhlunga udizili zivimbekile ngenxa yokungcoliswa kukawoyela, kuzodala ukutholakala kukawoyela okwanele futhi kunciphise amandla enjini. nokwenza kube nzima ukuqala.Gcoba uwoyela ekucindezelweni okuthile ngephampu yesandla bese ukhulula isikulufu sokungenisa umoya.Uma kukhona ama-bubbles echichima futhi ukukhishwa akuqedi ngaso sonke isikhathi, kusho ukuthi isifunda samafutha sigcwele umoya.Uma engekho amabhamuza, kodwa uwoyela wedizili uchichima ku-screw ye-bleeder, umjikelezo kawoyela uyavinjwa.Into evamile ukukhulula kancane isikulufu somoya ovulekile bese ufafaza ngokushesha ikholomu kawoyela ngengcindezi ethile.Indlela yokuxazulula inkinga ukuthola i-gasket eyonakele noma egugile, ipayipi elihlangene noma likawoyela bese ulibuyisela esikhundleni.Indlela yokuvimbela amaphutha anjalo iwukuhlanza isikrini sesihlungi esingenisa uwoyela kanye nesici sokuhlunga udizili njalo, hlola ipayipi njalo, futhi uxazulule izinkinga ngesikhathi lapho zitholakala.

2. Ipiston yepompo yokulethwa kwamafutha iphukile

Ijeneretha yedizili isetha izitebele ngokuzumayo ngesikhathi sokusebenza futhi ayikwazi ukuqaliswa.Khulula isikulufu sokopha futhi uhlole ukuthi uma kungekho noma uphethiloli omncane egumbini likawoyela elinengcindezi ephansi yepompo yomjovo kaphethiloli, pompa uwoyela ngepompo yesandla kuze kube yilapho lonke igumbi likawoyela elinengcindezi ephansi ligcwala uwoyela, khipha umoya. bese uqala kabusha injini.Injini ibuyela kwesijwayelekile, kodwa izozivala futhi ngemuva kokushayela ibanga elithile.Lesi sigameko sephutha kungenzeka ukuthi isiphethu se-piston sepompo yokudlulisa uwoyela siphukile.Leli phutha lingaqedwa ngokuqondile.Khipha isikulufu bese ushintsha isiphethu.

3. I-valve yokuhlola yepompo yokudlulisa uwoyela ayivalwanga ngokuqinile

Isethi yejeneretha kadizili isebenza ngokujwayelekile ngemva kokuqala, kodwa kunzima ukuyiqala ngemva komlilo isikhathi esithile.Kukhona ukuchichima kwebhamuza lapho kuthukululwa isikulufu sokungenisa umoya.Ingaqalwa kuphela ngemva kokuba umoya usukhishiwe futhi.Leli phutha libangelwa kakhulu ukuvaleka okuxekethile kwevalvu yokuhlola yephampu yokudlulisa uwoyela.Indlela yokuhlola iwukuqaqa isikulufu se-oil outlet sephampu yokulethwa kukawoyela bese umpompa iphampu kawoyela ukuze ugcwalise umgodi kawoyela wejoyinti lokuphuma likawoyela.Uma izinga lamafutha ekuhlanganyeleni lehla ngokushesha, libonisa ukuthi i-valve yokuhlola ayivaliwe kahle.Khipha i-valve yokuhlola bese uhlola ukuthi uphawu luqinile yini, ukuthi i-valve yokuhlola iphukile noma ikhubazekile, nokuthi kukhona yini ukungcola okuyingxenye endaweni yesihlalo sokuvala.Ngokwesimo esithile, gaya indawo yokuvala bese ushintsha i-valve yokuhlola noma hlola i-valve spring ukuze uqede iphutha.Ngokuvamile, izinga likawoyela alehli phakathi nemizuzu engaphezu kwengu-3, ​​futhi ikholomu kawoyela yephampu ikhishwa ngokuqinile ekuhlanganyeleni kokukhipha uwoyela.

4. Ipayipi likawoyela elinomfutho ophezulu livinjiwe

Lapho ipayipi likawoyela elinomfutho ophezulu we-cylinder livinjiwe ngenxa yokuguquguquka noma ukungcola, kungase kube nomsindo ongqongqozayo osobala epayipini likawoyela ngemva kokuqala. Yuchai diesel generator , futhi amandla esethi yejeneretha yedizili ayancipha ngoba isilinda asikwazi ukusebenza ngendlela evamile.Indlela yokuhlola iwukukhulula inati ekugcineni kwe-oyili yepayipi le-high-pressure oil pipe cylinder.Lapho umsindo ongqongqozayo unyamalala ngemva kokukhulula isilinda, kungaphetha ngokuthi isilinda siyisilinda esinephutha, futhi iphutha lingaqedwa ngemva kokufaka ipayipi likawoyela.

5. Ukuhlangana komjovo wesibaseli kubhajwe

Lapho i-valve yenaliti yomjovo ibambeke endaweni evaliwe, kuzwakala umsindo wokungqongqoza ovamile eduze kwekhanda lesilinda.Kubangelwa umthelela wegagasi lokucindezela lephampu yomjovo kaphethiloli kumjovo kaphethiloli.Indlela yokwahlulela iwukukhulula ipayipi likawoyela elinomfutho ophezulu oxhunywe ekugcineni komjovo.Uma umsindo ongqongqozayo uphela ngokushesha, kungaphetha ngokuthi i-valve yenaliti ye-injector yalesi silinda ibanjiwe.
