Incwadi yoYilo yeGumbi leGenereyitha yeDizili

Uyilo kunye nokufakelwa kwegumbi le-diesel generator kufuneka lihlangabezane neemfuno ezingezantsi :

1.Yenza ukugquma kwesandi kwigumbi le-diesel generator ukwenza ingxolo ngaphandle kwegumbi ukuhlangabezana nemida yazo naziphi na iinkcukacha.

2.I-air inlet kunye ne-exhaust ilungelelaniswa, kwaye i-ventilation kunye ne-heat dissipation effect ibonakala.

3.Unyango lokufunxa isandi.Iindonga ezintlanu kwigumbi lomatshini ngaphandle komhlaba zingasetyenziselwa unyango lokufunxa isandi.

I-4.Gense ine-vibration yodwa.

5.Yilungise ngokufanelekileyo inkqubo yokukhanyisa.

Isiseko sejeneretha yedizili:

Iseti yejenereyitha yedizili umsebenzi kufuneka uhlangabezane neemfuno ezingezantsi:

I-1.Kufuneka ikwazi ukuxhasa bonke ubunzima obumanzi besethi ye-generator, kubandakanywa izixhobo ezincedisayo kunye nolwelo lomatshini (olupholileyo, ioli kunye namafutha)

2.Gcina kwaye uzinzise indawo yokufakela phakathi kwe-injini, i-generator kunye nezixhobo ezincedisayo.

3.I-Isolate impembelelo ye-generator set vibration kwizakhiwo ezijikelezileyo.

Ukuba isiseko sekhonkrithi siyafuneka, iindlela zoyilo ezisisiseko zezi zilandelayo:

1.Amandla kufuneka akwazi ukuxhasa ubunzima obumanzi bejeneretha ye-diesel, kunye ne-25% yomthwalo oguqukayo.Xa ijenereyitha isebenza ngokufanayo, kufuneka ithwale kabini ubunzima obumanzi.

2.I-dimension iyonke kufuneka yandise ubuncinane i-300mm ngaphaya komphetho wesethi ye-generator.

3. Ubunzulu besiseko se-injini kufuneka bube bukhulu kunobunzulu xa isiseko se-injini sinokuthwala ubunzima obumanzi be-injini.

Le fomula ilandelayo ingasetyenziselwa ukuqikelela ubunzulu besiseko esinokuthwala ubunzima beseti yejenereyitha:

FD=Ubunzulu besiseko, iyunithi: M

W= ubunzima bubonke be-genset, iyunithi: KG

D=Ubuninzi bekonkrithi, iyunithi: kg/m3(2402.8kg/m3)

L=ubude besiseko, iyunithi: imitha

B=ububanzi besiseko, iyunithi: imitha

Isiseko sekhonkrithi esomeleziweyo kufuneka siqinisekise ixesha elithile lokunyanga ngaphambi kokuba isixhobo sibe nendawo.

Xa umhlaba wegumbi lomatshini i-slab yomgangatho okanye isakhiwo sekhonkrithi, isiseko sesakhiwo esiboniswe kumzobo ongezantsi singamkelwa.Isiseko sekhonkrithi 100mm ~ 200mm ukuphakama kunomhlaba siya kudityaniswa ne slab yomgangatho.Uqhagamshelwano nomgangatho:

1.Nokuba i-welding kunye nokuqiniswa komgangatho.

2.Embedded bar welding.

3.Ukwandiswa kwe-screw welding.

Inkqubo yokungenisa umoya yegumbi lomatshini:

Ukungena komoya kwigumbi lomatshini ubukhulu becala kukubonelela komoya owaneleyo wokupholisa ukususa ubushushu besethi yejeneretha, kunye nokubonelela ngomoya owaneleyo wokutsha.Nangona kunjalo, ukuhamba komoya kufuneka kulawulwe ukuze kungachaphazeli intuthuzelo yabaqhubi.

V = Umthamo wokungenisa umoya (m3/min)

H = Ubushushu obukhanyayo obuvela kwi-generator iseti kwigumbi lomatshini (kW), (Kwi-25 ℃, inokufumaneka kwitheyibhile yeparameter yobugcisa)

Ukulungiswa kwemeko kwamanye amaqondo obushushu DCF = -.011* TER +1.3187 (TER = Olona bushushu bomatshini umatshini °C)

Umoya ovuthayo= Imfuno yomoya wokutsha (m3/min)

D = Uxinzelelo lomoya , 1.099 kg/m3 (38℃ 时）

CP = Ubushushu obukhethekileyo bomoya (0.017 kw*min/kg℃)

ΔT = Ukunyuka kwamaqondo obushushu avumelekileyo kwigumbi lomatshini (°C)(Qaphela: ubushushu obuphezulu begumbi lomatshini yi-49°C)

F = I-coefficient yendlela yokungenisa umoya (njengoko kubonisiwe kulo mfanekiso ungezantsi):

Ufakelo oludibeneyo lwe-radiator kunye ne-injini, iimfuno zomoya zegumbi lomatshini zimi ngolu hlobo lulandelayo:

V = ukuhamba komoya kwefeni yeradiyetha + imfuno yomoya yokutsha.

Uxinzelelo lwangasemva lokuhamba komoya kwindawo yokuphuma kwitanki lamanzi okupholisa aluyi kuba ngaphezu kwe-0.1275kPa.

Indawo yesigqubuthelo somoya weradiyetha ikholisa ukuba mkhulu ngokuphindwe kayi-1.5 kunondoqo weradiyetha.

Inkqubo yokupholisa injini:

Ibhalansi yobushushu kwisixokelelwano se-injini:

40%—Emsebenzini

I-30-40% -ukukhupha umoya

20-40% -ukupholisa

I-6-8% -I-Friction kunye ne-radiation

Ubushushu obuthathwe yinkqubo yokupholisa buvela kula malungu mathathu alandelayo:

1.I-Cylinder liner water circuit

2.I-oyile yokuthambisa i-cooler

3.Turbocharger aftercooler

Imowudi yesekethe yokupholisa engundoqo:

1.Isekethi yokupholisa eyohlukeneyo (oko kukuthi isixokelelwano ngasinye kwezi zintathu zingentla zenza isekethe)

2.I-Hybrid cooling circuit (okt ezi sistim ezintathu okanye ezimbini zingasentla zenza isekethe)

3.Isekethi yokupholisa yomoya ukuya kumoya (oko kukuthi umoya oshushu emva kwe-turbocharging upholiswe ngumoya wefeni)

Uhlobo lwesixokelelwano sokupholisa:

1.Inkqubo yokupholisa evulekileyo: kuquka inqaba yokupholisa (ngaphandle kokutshintsha ubushushu), ichibi lokutshiza kunye nomthamo omkhulu wamanzi.(ayinconywa).

2.Isixokelelwano sokupholisa esivaliweyo: kubandakanywa inqaba yokupholisa (kuquka i-heater) okanye i-radiator ye-fan, i-heat exchanger, i-evaporative cooler, njl.

Ukuhlelwa kweeradiyetha:

1. Iradiyetha efakwe kwi-injini.

2. Irediyetha ekude: ayisayi kuba yi-17.4 m ukuphakama kunempompo yamanzi ye-injini ukunqanda ukuvuza okubangelwa luxinzelelo olugqithisileyo olonakalise itywina lempompo yamanzi.

Xa lo mphakamo ugqithiswa, utshintshiselwano lokushisa lunokusetyenziswa okanye itanki yamanzi eguqukayo (iqula elishushu) linokufakwa kwisekethe yokujikeleza kwamanzi.

Irediyetha ethe nkqo: ifeni yokupholisa ivuthela ngokuthe tye.

Iradio ethe tye ekude r: ifeni yokupholisa ivuthela phezulu (nikela ingqalelo ukuthintela imvula, ikhephu kunye neFrost).

Izitshintshi zobushushu : iqokobhe kunye ityhubhu kunye nepleyiti.

Inqaba yokupholisa:

Xa inkqubo yokupholisa idinga ubushushu obuphantsi (umzekelo, i-post yokupholisa isiphaluka ngamanye amaxesha idinga i-54 ℃ okanye i-32 ℃), inokuqwalaselwa ukwenza.

Sebenzisa inqaba yokupholisa, okanye kufuneka usebenzise amanzi omlambo, amanzi echibi ukupholisa, njl.

Kukho iinqaba zokupholisa ezivulekileyo nezivaliweyo.

Ngaphezulu kwecandelo loku-1 lemanyuwali yoyilo ye best standby generator , ngenxa yexesha elilinganiselweyo, sinokubelana kuphela ngeenxalenye ezithile.Siza kwabelana ngenxalenye yesi-2 ngosuku olulandelayo, nceda ulandele inqaku lethu elilandelayo ukuze ufumane ulwazi oluthe kratya malunga negumbi le-diesel generator.
