Iimpazamo eziqhelekileyo kunye nezisombululo zeNkqubo yeFuel yeSeti yeGenereyitha

Inkqubo ye-fuel ye-diesel generator set yeyona ndawo ingundoqo.Ukongeza kokunxiba kwangaphambili kweendawo ezintathu zokudityaniswa okuchanekileyo kwenkqubo yamafutha, okukhokelela ekunciphiseni amandla ejenereyitha, ukwanda kokusetyenziswa kwamafutha kunye nokukhupha umsi, kukho iindidi ezimbini zeempazamo ezinokuthi zenzeke kwinkqubo yamafutha: enye. yimpazamo ebangelwa kukufakelwa ngokungafanelekanga kwempompo yokutofa kwamafutha, kwaye enye yimpazamo ekusebenziseni.

A.Ukusilela okubangelwa kukufakelwa ngokungafanelekanga kwempompo yokutofa kwamafutha iseti yejenereyitha yedizili

1. Iqhosha le-semicircular alifakwanga endaweni

Kwimpompo yokutofa kwepetroli edityaniswe ngeflange, xa indawo yofakelo lwesitshixo semisetyhula phakathi kwegiya yexesha lokubonelela ngamafutha kunye nolawulo oluzenzekelayo lwe-angle yonikezelo lwamafutha kwangaphambili kunye necamshaft yempompo yokutofa kwamafutha ayichanekanga, kuya kubakho ukungahambi kakuhle kwexesha lokubonelela ngamafutha. , ukuqala kwe-injini enzima, umsi kunye nobushushu obuphezulu bamanzi.Ukuba ayinakulungelelaniswa kumngxuma we-arc kwi-flange, impompo yesitofu se-fuel kufuneka isuswe kwaye ifakwe kwakhona.Emva kokususwa, ukunyuswa okucacileyo kunokubonwa kwiqhosha le-semicircular.

2. I-oyile yokungena kunye nezikrufu zokubuyisela zifakwe ngokungalunganga

Xa udibanisa umbhobho weoli, ukuba i-oyile yokubuyisela i-screw ifakwe ngokungalunganga kwi-oil inlet pipe joint of the fuel injection pump, ngenxa yesenzo se-valve yokukhangela kwi-screw yokubuyisela ioli, i-fuel ayikwazi ukungena okanye ingena kuphela inani elincinci. i-oil inlet room yepompo ye-injection ye-fuel, ukwenzela ukuba isethi ye-diesel generator ayikwazi ukuqaliswa okanye ayikwazi ukufakwa i-refueled emva kokuqala ukunyusa isantya.Ngeli xesha, impompo yesandla inokumelana okukhulu nokumpompa ioyile, kwaye ayinakukwazi ukucinezela impompo yesandla.Ngeli xesha, impazamo inokupheliswa nje ukuba izikhundla zofakelo lwe-oyile yokungena kunye nezikrini zokubuyisela zitshintshwa.

B.Iimpazamo eziqhelekileyo ekusebenziseni iseti yejenereyitha yedizili

1. Unikezelo lwe-oyile engalunganga yesekethe yeoli yoxinzelelo oluphantsi

Isingeno se-oyile kunye nemibhobho yokubuyisela ijenereyitha yedizili eseti ukusuka kwitanki yeoli ukuya kwigumbi lokungena ioyile yempompo yokutofa ngamafutha yeyesekethi ye-oyile enoxinzelelo oluphantsi.Xa umbhobho we-oyile edibeneyo, i-gasket kunye ne-oyile ivuza ngenxa yomonakalo, umoya uya kungena kwisekethe yeoli ukuvelisa ukuxhathisa komoya, okukhokelela kubonelelo lwe-oyile olulambathayo, ukuqala kwe-injini enzima, ukukhawulezisa okucothayo kunye nezinye iimpazamo, kwaye ngokuzenzekelayo kuya kuvalwa ngokuzenzekelayo. iimeko.Xa indawo enqamlezayo yombhobho we-oyile iyancipha ngenxa yokuguga, ukuguqulwa kunye nokungcola, okanye isikrini sokucoca i-oyile kunye ne-diesel filter element ivaliwe ngenxa yongcoliseko lwe-oyile, iya kubangela ukunikezelwa kweoli eyaneleyo kunye nokunciphisa amandla enjini. kwaye wenze kube nzima ukuqala.Pump i-oyile kuxinzelelo oluthile ngempompo yesandla kwaye ukhulule isikrufu sokuphuma.Ukuba kukho amaqamza aphuphumayo kwaye ukukhutshwa akugqitywanga lonke ixesha, kuthetha ukuba isiphaluka seoli sizaliswe ngumoya.Ukuba akukho amaqamza, kodwa i-oyile ye-diesel iphuphuma kwi-screw ye-bleeder, i-oil circuit ivaliwe.Into eqhelekileyo kukukhulula kancinci isikrufu somoya ovulekileyo kwaye ngokukhawuleza utshize ikholamu yeoli ngoxinzelelo oluthile.Indlela yokusombulula ingxaki kukufumana i-gasket eyonakeleyo okanye egugayo, i-joint or oil pipe kwaye uyitshintshe.Indlela yokuthintela ezo mpazamo kukucoca isihluzo se-oyile yesihluzi se-oyile kunye nesixhobo sokucoca idizili rhoqo, jonga umbhobho rhoqo, kwaye uzisombulule iingxaki ngexesha xa zifunyenwe.

2. Ipiston yempompo yokuhanjiswa kweoyile yaphukile

Ijenereyitha ye-diesel iseti ngokukhawuleza izitali ngexesha lokusebenza kwaye ayikwazi ukuqaliswa.Khulula i-screw ye-bleed kwaye ukhangele ukuba akukho mafutha amancinci kwigumbi le-oyile yoxinzelelo oluphantsi lwempompo yokutofa kwamafutha, pompa i-oyile ngempompo yesandla de igumbi lonke eliphantsi koxinzelelo lweoyile lizaliswe yioyile, khupha umoya. kwaye uqale kabusha injini.I-injini ibuyela kwesiqhelo, kodwa iya kuzivala ngokuzenzekelayo kwakhona emva kokuqhuba umgama othile.Le mpazamo inokwenzeka ukuba i-piston spring yepompo yokuhambisa ioyile yaphukile.Le mpazamo inokupheliswa ngokuthe ngqo.Khulula isikrufu kwaye ubuyisele intwasahlobo.

3. I-valve yokutshekisha yepompo yokuhambisa ioli ayivalwanga ngokuqinileyo

Iseti yejenereyitha yedizili isebenza ngokwesiqhelo emva kokuqalisa, kodwa kunzima ukuqalisa emva kokutsha kwedangatye ixesha elithile.Kukho iqamza eliphuphumayo xa ukhulula isikrufu sokungena.Inokuqaliswa kuphela emva kokuba umoya ukhutshiwe kwakhona.Le mpazamo ibangelwa kakhulu kukutywinwa okuxekethileyo kwevalve yokutshekisha yempompo yokuhambisa ioyile.Indlela yokuhlola kukukhulula isikrufu sokuphuma kwe-oyile sempompo yokuhanjiswa kwe-oyile kunye nokumpompa impompo ye-oyile ukuze igcwalise umngxuma we-oyile wejoyini yokuphuma kwe-oyile.Ukuba inqanaba leoli kwi-joint yehla ngokukhawuleza, libonisa ukuba i-valve yokutshekisha ayivalwanga kakuhle.Susa ivalve yokutshekisha kwaye ujonge ukuba isitywina sichanekile na, nokuba ispringi sevalve yokukhangela yophukile okanye ikhubazekile, kwaye ingaba kukho ukungcola okukuyo kwindawo yokutywina.Ngokwemeko ethile, gaya indawo yokutywina kwaye utshintshe i-valve yokutshekisha okanye ukhangele i-valve spring ukuphelisa impazamo.Ngokuqhelekileyo, inqanaba leoli aliyehli ngaphezu kwemizuzu engama-3, kwaye ikholamu yeoli yempompo ikhutshwe ngamandla kwi-oil outlet joint.

4. Umbhobho we-oyile woxinzelelo oluphezulu uvaliwe

Xa umbhobho we-oyile woxinzelelo oluphezulu we-cylinder uvaliwe ngenxa yokuguqulwa okanye ukungcola, kunokubakho isandi esicacileyo sokunkqonkqoza kumbhobho weoyile emva kokuqala. Iijenereyitha zedizili zaseYuchai , kwaye amandla esethi ye-diesel generator ayancipha ngenxa yokuba i-cylinder ayikwazi ukusebenza ngokuqhelekileyo.Indlela yokuhlola kukukhulula i-nut kwi-oil inlet end of the high-pressure oil pipe cylinder by cylinder.Xa isandi sokunkqonkqoza sinyamalala emva kokukhulula i-cylinder, kunokugqitywa ukuba i-cylinder i-cylinder ephosakeleyo, kwaye impazamo inokupheliswa emva kokutshintshwa kombhobho weoli.

5. Ukudityaniswa kwesitofu se-fuel kubambekile

Xa ivelufa yenaliti yokutofa ibambeke kwindawo evaliweyo, kukho isandi sokunkqonkqoza rhoqo kufutshane nentloko yesilinda.Ibangelwa yimpembelelo yoxinzelelo lwamaza epompo yokutofa ngamafutha kwi-injector yamafutha.Indlela yokugweba kukukhulula umbhobho we-oyile woxinzelelo oluphezulu oludityaniswe nesiphelo se-injector.Ukuba isandi sokunkqonkqoza siyanyamalala ngokukhawuleza, kunokugqitywa ukuba i-valve yenaliti ye-injector yale cylinder ibambekile.
