Imanuwali yokudizayina yeGumbi leGeneretha yeDizili

Ukwakhiwa nokufakwa kwegumbi lokuphehla udizili kumele kuhlangabezane nezidingo ezingezansi :

1.Yenza ukuvala umsindo kwegumbi lejeneretha likadizili ukuze wenze umsindo ngaphandle kwegumbi uhlangabezane nemikhawulo yanoma yiziphi izincazelo.

I-2.I-air inlet kanye ne-exhaust ilinganisela, futhi umphumela wokungenisa umoya nokushisa uyabonakala.

3.Ukwelashwa kokumunca umsindo.Izindonga ezinhlanu ekamelweni lomshini ngaphandle kwenhlabathi zingasetshenziselwa ukwelashwa kokumuncwa komsindo.

I-4.Gense inokuhlukaniswa kokudlidliza.

5.Lungisa ngokunengqondo uhlelo lokukhanyisa.

Isisekelo se-Diesel generator set:

Isethi yejeneretha yedizili umsebenzi kufanele uhlangabezane nezimfuneko ezingezansi:

I-1.Kumelwe ikwazi ukusekela sonke isisindo esimanzi sesethi ye-generator, kuhlanganise nemishini eyisizayo kanye noketshezi lomshini (okupholile, uwoyela kanye nophethiloli)

2.Londoloza futhi uzinzise indawo yokufaka phakathi kwenjini, ijeneretha kanye nezinto ezisizayo.

3.Hlukanisa umthelela wokudlidliza kwesethi yejeneretha ezakhiweni ezizungezile.

Uma kudingeka isisekelo sikakhonkolo, imibandela yokuklama eyisisekelo yilena elandelayo:

1.Amandla kumele akwazi ukusekela isisindo esimanzi sejeneretha yedizili, kanye no-25% womthwalo oguqukayo.Uma ijeneretha isebenza ngokuhambisana, kufanele ithwale isisindo esiphindwe kabili kunesisindo esimanzi.

2.Ubukhulu obuphelele kufanele bunwebe okungenani ngo-300mm ngaphezu konqenqema lwesethi yejeneretha.

3.Ukujula kwesizinda senjini kumele kube kukhulu kunokushona lapho isizinda senjini singathwala isisindo esimanzi senjini.

Ifomula elandelayo ingasetshenziswa ukulinganisa ukujula kwesisekelo esingathwala isisindo sesethi yejeneretha:

FD=Ukujula kwesisekelo, iyunithi: M

W= isisindo esiphelele se-genset, iyunithi: KG

D=Ukuminyana kukakhonkolo, iyunithi: kg/m3 (2402.8kg/m3)

L=ubude besisekelo, iyunithi: imitha

B=ububanzi besisekelo, iyunithi: imitha

Isisekelo sikakhonkolo esiqinisiwe kufanele siqinisekise isikhathi esithile sokuphulukisa ngaphambi kokuba okokusebenza kube khona.

Lapho inhlabathi yegumbi lomshini i-slab yaphansi noma isakhiwo sikakhonkolo, isisekelo sesakhiwo esiboniswe esithombeni esingezansi singamukelwa.Isisekelo sikakhonkolo esingu-100mm ~ 200mm ukuphakama kunomhlaba sizoxhunywa ne-floor slab.Ukuxhumana nesitezi:

1.Ngisho ukushisela nge-floor reinforcement.

2.Embedded ibha welding.

3.Ukushisela isikulufu sokunweba.

Isistimu yokungenisa umoya yegumbi lomshini:

Ukungena komoya ekamelweni lomshini ngokuyinhloko ukunikeza umoya opholile owanele ukuze kususwe ukuchithwa kokushisa kwesethi ye-generator, kanye nokuhlinzeka ngomoya owanele wokuvutha.Nokho, ukugeleza komoya kufanele futhi kulawulwe ukuze kungathinti ukunethezeka kwabaqhubi.

V = Ivolumu yokungenisa umoya (m3/min)

H = Ukushisa okukhazimulayo okuvela kujeneretha kusethwe egumbini lomshini (kW), (Ku-25 ℃, kungatholakala kuthebula lepharamitha yezobuchwepheshe)

Isici sokulungisa kwamanye amazinga okushisa DCF = -.011* TER +1.3187 (TER = Iqondo lokushisa langempela legumbi lomshini°C)

I-Combustion Air= Isidingo somoya ovuthayo(m3/min)

D = Ukuminyana komoya , 1.099 kg/m3 (38℃ 时)

CP = Ukushisa okuqondile komoya (0.017 kw*min/kg℃)

ΔT = Ukukhuphuka kwezinga lokushisa okuvumelekile kwegumbi lomshini (°C)(Qaphela: izinga lokushisa eliphezulu legumbi lomshini ngu-49°C)

F = I-coefficient yomzila wokungenisa umoya (njengoba kukhonjisiwe esithombeni esingezansi):

Ukufakwa okuhlanganisiwe kwe-radiator nenjini, izidingo zokungenisa umoya zegumbi lomshini zimi kanje:

V = ukugeleza komoya kwe-radiator fan + isidingo somoya ovuthayo.

Umfutho wangemuva wokugeleza komoya lapho uphuma khona ithangi lamanzi okupholisa akufanele udlule u-0.1275kPa.

Indawo yekhava yomhlahlandlela womoya werediyetha ngokuvamile inkulu ngokuphindwe ka-1.5 kunaleyo yomgogodla werediyetha.

Isistimu yokupholisa injini:

Ibhalansi yokushisa yesistimu yenjini:

40%—Umsebenzi

30-40% - umoya wokuqeda

20-40% - ukupholisa

6-8% - Ukungqubuzana kanye nemisebe

Ukushisa okuthathwa yisistimu yokupholisa kuvela ezingxenyeni ezintathu ezilandelayo:

I-1.Cylinder liner water circuit

2.Isipholile samafutha okugcoba

3.I-Turbocharger aftercooler

Imodi yesekethe yokupholisa eyinhloko:

1.Isekhethi yokupholisa ehlukene (okungukuthi isistimu ngayinye yokupholisa emithathu engenhla yenza isekethe)

2.Isekhethi yokupholisa yeHybrid (okungukuthi amasistimu amathathu noma amabili angenhla enza isekethe)

3.Isekhethi yokupholisa komoya kuye emoyeni (okungukuthi, umoya oshisayo ngemuva kwe-turbocharging upholiswa ngumoya wefeni)

Ifomu lesistimu yokupholisa:

1.Isistimu yokupholisa evulekile: kufaka phakathi umbhoshongo wokupholisa (ngaphandle kwesishintshi sokushisa), ichibi lokufutha kanye nenani elikhulu lamanzi.(akunconyiwe).

2.Isistimu yokupholisa evaliwe: okufaka umbhoshongo wokupholisa (okuhlanganisa isishintshi sokushisa) noma irediyetha yefeni, isishintshi sokushisa, isipholile esihwamukayo, njll.

Izigaba zama-radiator:

1. Irediyetha efakwe injini.

2. Irediyetha yesilawuli kude: akufanele iphakame ngo-17.4 m kunepompo yamanzi enjini ukuze kugwenywe ukuvuza okubangelwa ukucindezela okukhulu okulimaza uphawu lwepompo yamanzi.

Uma lokhu kuphakama kudlula, isishintshi sokushisa singasetshenziswa noma ithangi lamanzi elishintshayo (umthombo oshisayo) lingafakwa kumjikelezo wokujikeleza kwamanzi.

Irediyetha yesilawuli kude esime mpo: ifeni yokupholisa iphuma ivundlile.

Irediyo eyirimothi evundlile r: isiphephetha-moya esipholile siphephezela phezulu (naka ukuze uvimbele imvula, iqhwa nesithwathwa).

Izishintshi zokushisa : igobolondo neshubhu nepuleti.

Umbhoshongo wokupholisa:

Lapho isistimu yokupholisa idinga izinga lokushisa eliphansi (isibonelo, isekethe yokupholisa okuthunyelwe ngezinye izikhathi idinga u-54 ℃ noma 32 ℃), ingacatshangwa ukuthi yenza

Sebenzisa umbhoshongo wokupholisa, noma udinga ukusebenzisa amanzi omfula, amanzi echibi ukupholisa, njll.

Kunemibhoshongo yokupholisa evuliwe nevaliwe.

Ngaphezulu kwengxenye 1 yemanuwali yokuklama ye best standby generator , ngenxa yesikhathi esilinganiselwe, singaba izingxenye ezithile kuphela.Sizokwabelana ngengxenye yesi-2 ngosuku olulandelayo, sicela ulandele isihloko sethu esilandelayo ukuze uthole ulwazi olwengeziwe mayelana negumbi lokuphehla udizili.
