Ungawabona Kanjani AmaGeneretha Kadizili angamanga

Njengoba sonke sazi, isethi generator diesel ikakhulukazi ihlukaniswe izingxenye ezine: injini diesel, generator, uhlelo lokulawula kanye izesekeli.Inqobo nje uma enye yazo ingumkhiqizo womgunyathi, ingase ithinte inani eliphelele kanye nokusebenza kokusebenza kwesethi yejeneretha likadizili.Ngakho kufanele sifunde ukuhlukanisa.Namuhla, i-Dingbo Power ikufundisa ukukhomba amasethi ejeneretha e-diesel mbumbulu.

1.Injini kadizili

Injini ye-diesel iyingxenye yamandla eyunithi yonke, ibalwa ku-70% wezindleko zesethi ye-generator diesel.Yisixhumanisi abanye abakhiqizi ababi abathanda ukukhohlisa.

1.1 Injini ye-diesel engelona iqiniso

Njengamanje, iningi lezinjini zikadizili ezaziwayo emakethe zinabakhiqizi bokulingisa.Isibonelo, i-Volvo, injini ye-diesel ekhiqizwa inkampani ifana ncamashi nenjini ye-Volvo.Basebenzisa isihlungi somoya sakwaVolvo sokuqala, bese bemaka uphawu lwe-VOLVO enjinini kadizili.Isibonelo, i-Cummins, injini yedizili ekhiqizwa inkampani, ithi isikulufu ngasinye siyafana ne-Cummins, futhi ngisho nemodeli ifana kakhulu.Manje sekunemikhiqizo eminingi mbumbulu emakethe, ngakho kunzima ukuhlukanisa phakathi kweqiniso namanga.

Abakhiqizi ababi basebenzisa le mishini yomgunyathi enesimo esifanayo ukuze bazenze abadumile, basebenzise namapuleti mbumbulu, izinombolo zoqobo, ukuphrinta izinto zasembonini zomgunyathi nezinye izindlela zokudida leyo mbumbulu neyangempela, ukuze kube nzima ngisho nochwepheshe ukuhlukanisa. .

Umkhiqizi ngamunye omkhulu wenjini kadizili uneziteshi zesevisi ngemuva kokuthengiswa ezweni lonke.Kushiwo kwinkontileka ne Umkhiqizi wesethi ye-generator   ukuthi uMdayisi uqinisekisa ukuthi injini kadizili iyinjini kadizili entsha sha futhi eyiqiniso esetshenziswa isitshalo sokuqala sesitshalo esithile, futhi imodeli ayiphazanyiswa.Uma kungenjalo, owamanga uzonxeshezelwa ngeshumi.Umphumela wokulinganisa wesiteshi sesevisi sangemva kokuthengisa sefekthri ethile kanye nendawo ethile uyosebenza, futhi umthengi uzothinta izindaba zokulinganisa, futhi izindleko zizokhokhwa umthengi.Bhala phansi igama eliphelele lomkhiqizi.Uma nje uphikelela ekubhaleni lesi sihloko kwinkontileka futhi uthi kufanele wenze i-appraisal, abakhiqizi ababi abasoze balokotha ukuthatha le ngozi.Iningi labo lizokwenza ikhotheshini entsha futhi likunikeze inani langempela eliphakeme kakhulu kunekhotheshini yangaphambilini.

1.2 ukulungiswa kwemishini emidala

Zonke izinhlobo zinemishini emidala elungiswe kabusha.Ngokufanayo, ababona ochwepheshe, okunzima ukuhlukanisa.Kodwa ngaphandle kokunye, akukho nhlobo ukuhlonza.Isibonelo, abanye abakhiqizi bangenisa ukuvuselelwa kwenjini endala yamasethi e-generator brand diesel avela kwamanye amazwe, ngoba lelo zwe linabakhiqizi abadumile bomkhiqizo.Laba bakhiqizi ababi bathi bangamasethi akhiqiza udizili ohlobo lwangempela angenisiwe, futhi banganikeza nezitifiketi zeCustoms.

1.3 ukudida umphakathi ngamagama emboni afanayo

Laba bakhiqizi ababi banamahloni kancane, abalokothi benze ideski kanye nokuvuselela, futhi badide umphakathi namagama ezinjini zikadizili zabakhiqizi abafanayo.

Indlela endala isasetshenziswa ukubhekana nabakhiqizi abanjalo.Igama eliphelele lenjini yokuqala kadizili libhaliwe kwinkontileka, kanti isiteshi sesevisi sangemuva kokuthengisa siyakuhlonza.Uma kuwumgunyathi, abayishumi ngekhefu elilodwa bazohlawuliswa.Abakhiqizi abanjalo banamahloni.Abaningi babo bashintsha amagama abo ngokushesha nje lapho usho.

1.4 inqola encane edonsa amahhashi

Ukudida ubudlelwane phakathi kwe-KVA ne-kW.Phatha i-KVA njenge-kW, yenza ihaba amandla futhi uwadayisele amakhasimende.Eqinisweni, i-KVA ingamandla asobala futhi i-kW ingamandla asebenzayo.Ubudlelwano phakathi kwabo 1kVA = 0.8kw.Amayunithi angenisiwe ngokuvamile avezwa nge-KVA, kuyilapho okokusebenza kukagesi wasekhaya ngokuvamile kuvezwa nge-kW, ngakho-ke lapho kubalwa amandla, i-KVA kufanele iguqulelwe ku-kW.

Amandla enjini kadizili ahlelwe abe makhulu njengawejeneretha ukuze kwehliswe izindleko.Eqinisweni, imboni ngokuvamile ibeka ukuthi amandla enjini kadizili angu-≥ 10% wamandla e-generator, ngoba kukhona ukulahleka kwemishini.Okubi nakakhulu, abanye babikele umthengi amandla ehhashi lenjini kadizili njenge-kW, futhi balungisa iyunithi ngenjini kadizili engaphansi kwamandla e-generator, okuholele ekunciphiseni ukuphila kweyunithi, ukulondolozwa njalo kanye nezindleko ezikhulayo.

Ukuhlonza kudinga kuphela ukubuza mayelana namandla aphambili kanye namandla okulinda enjini kadizili.Ngokuvamile, abakhiqizi besethi yamajeneretha abalokothi bafake lezi datha ezimbili mbumbulu, ngoba abakhiqizi benjini yedizili bashicilele idatha yenjini yedizili.Amandla aphambili kuphela kanye nawokubekwe eceleni enjini kadizili aphezulu ngo-10% kunalawo esethi yejeneretha.

2. I-alternator

Umsebenzi we-alternator ukuguqula amandla enjini ye-diesel ibe ugesi, okuhlobene ngokuqondile nekhwalithi kanye nokuzinza kukagesi ophumayo.Abakhiqizi besethi ye-Diesel generator banamajeneretha amaningi azenzelayo, kanye nabakhiqizi abaningi abaziwayo abasebenza ngokukhiqiza kuphela amajeneretha.

Ngenxa yomkhawulo ophansi wobuchwepheshe bokukhiqiza wama-alternator, generator diesel abakhiqizi ngokuvamile bakhiqiza ama-alternator abo.Ukuze kucatshangelwe ukuncintisana kwezindleko, ama-alternator amabhrendi amaningana adumile emhlabeni nawo amise izimboni e-China ukuze afeze ukwenziwa kwasendaweni okuphelele.

2.1 stator core silicon steel sheet

I-stator core yenziwe nge-silicon steel sheet ngemuva kokugxiviza nokushisela.Izinga le-silicon steel sheet lihlobene ngokuqondile nosayizi we-stator magnetic field circulation.

2.2 impahla yekhoyili ye-stator

Ikhoyili ye-stator ekuqaleni yayakhiwe ngazo zonke izintambo zethusi, kodwa ngokuthuthuka kobuchwepheshe bokwenza izintambo, kwavela intambo yomgogodla ye-aluminium ene-copper-clad.Ihlukile kuntambo ye-aluminiyamu ene-copper-plated, i-copper-clad aluminium core wire isebenzisa isipesheli.Lapho ucingo lokuhlala lwakhiwe, ungqimba lwe-aluminium olugqoke ithusi lushubile kune-copper-plated.Ikhoyili ye-jeneretha ye-stator isebenzisa i-copper-clad aluminium core wire, enomehluko omncane ekusebenzeni, kodwa impilo yayo yesevisi ifushane kakhulu kunayo yonke ikhoyili ye-stator yethusi.

Indlela yokuhlonza: i-copper clad aluminium core wire ingasebenzisa kuphela 5/6 pitch kanye nezikhala ezingu-48 kustator ye-copper-plated aluminium wire kanye ne-copper-plated aluminium wire.Intambo yethusi ingafinyelela ku-2/3 pitch kanye nezikhala ezingama-72.Vula ikhava yangemuva yenjini bese ubala inani lezikhala ze-stator core.

2.3 ukuphakama nokuphenduka kwekhoyili ye-stator

Zonke izintambo zethusi nazo ziyasetshenziswa, futhi ikhoyili ye-stator nayo ingenziwa ibe yi-5/6 pitch kanye namajika angama-48.Ngenxa yokuthi ikhoyili ingaphansi kokuphenduka okungama-24, ukusetshenziswa kocingo lwethusi kuyancishiswa, futhi izindleko zingancishiswa ngo-10%.I-2/3 pitch, i-72 turn stator ithatha i-diameter yocingo lwethusi oluncane, ukuphenduka okungu-30% ngaphezulu, amakhoyili amaningi ngokujika ngakunye, i-waveform yamanje ezinzile futhi akulula ukuyishisa.Indlela yokuhlonza iyafana nengenhla, kubalwa inani lezikhala ze-stator core.

2.4 i-rotor bear

I-rotor bearing yiyona kuphela ingxenye yokugqoka ku-generator.Ukuvunyelwa phakathi kwe-rotor ne-stator kuncane kakhulu, futhi ukuthwala akusetshenzisiwe kahle.Ngemuva kokugqoka, kulula kakhulu ukuthi i-rotor iguqe ngokumelene ne-stator, eyaziwa ngokuthi i-rubbing bore, ezokhiqiza ukushisa okuphezulu futhi ishise i-generator.

2.5 imodi yokuvusa

Imodi ye-excitation ye-generator ihlukaniswe yaba uhlobo lwe-excitation yesigaba kanye nohlobo lwe-brushless self excitation.Ukuzithokozisa okungenasisekelo sekuyinto evamile ngezinzuzo zokuvusa usinga ezinzile nokunakekelwa okulula, kodwa abanye abakhiqizi basalungisa amajeneretha avusa amadlingozi wesigaba kumayunithi akhiqiza ugesi angaphansi kuka-300kW ukuze kucatshangelwe izindleko.Indlela yokuhlonza ilula kakhulu.Ngokusho kwethoshi endaweni yokukhipha ukushisa yejeneretha, leyo enebhulashi iwuhlobo lokuvusa inhlanganisela yesigaba.

Ngenhla kukhona ezinye izindlela zokuhlonza amajeneretha edizili mbumbulu, vele, ngenhla yizindlela ezithile kuphela, ezingaphelele.Sethemba ukuthi lesi sihloko siwusizo kuwe uma uthenga amajeneretha edizili.
