Dhizaini Manual yeDiesel Jenareta Kamuri

Dhizaini uye kuisirwa dhiziri jenareta imba inofanirwa kusangana pazasi zvinodiwa :

1.Ita ruzha rwekudzivirira kwekamuri ye diesel jenareta kuita ruzha kunze kwekamuri kusangana nemiganhu yezvipi zvacho zvakatemwa.

2.Nhepfenyuro yemhepo uye kupera kwakadzikama, uye mhepo yemhepo uye kupisa kwekushisa kunooneka.

3.Sound absorption kurapwa.Madziro mashanu mukamuri yemuchina kunze kwepasi anogona kushandiswa kurapa kunyudzwa kwenzwi.

4.Gense ine vibration yekuzviparadzanisa nevamwe.

5.Reasonably gadzirisa hurongwa hwekuvhenekera.

Diesel generator set foundation:

Diesel jenareta seti basa rinofanira kusangana pazasi zvinodiwa:

1.Inofanirwa kukwanisa kutsigira huremu hwese hwejenareta seti, kusanganisira yekubatsira michina uye mvura yemuchina (inotonhorera, mafuta uye mafuta)

2.Kuchengetedza uye kudzikamisa nzvimbo yekuisa pakati pejini, jenereta uye midziyo yekubatsira.

3.Isolate kukanganisa kwejenereta set vibration pane zvakakomberedza zvivakwa.

Kana chigadziko chekongiri chichidikanwa, maitiro ekutanga ekugadzira ndeaya anotevera:

1.Simba rinofanira kukwanisa kutsigira uremu hwakanyorova hwejenereta dizeli, pamwe ne25% yemutoro wesimba.Kana jenareta ichishanda zvakafanana, inofanira kutakura uremu hwakanyorova kaviri.

2.The dimension yose inofanira kuwedzera zvishoma 300mm kupfuura kumucheto kwejenareta seti.

3.Kudzika kwechigadziko chejini kunofanira kunge kwakakura kudarika kudzika apo injini inogona kutakura uremu hwakanyorova hwejini.

Iyo inotevera fomula inogona kushandiswa kufungidzira kudzika kwebhesi iyo inogona kutakura huremu hwejenareta seti:

FD=Kudzika kwepasi, chikamu: M

W= huremu hwakazara hwegenset, unit: KG

D=Kuwanda kwekongiri, chikwata: kg/m3 (2402.8kg/m3)

L=kureba kwehwaro, chikwata: mita

B=hupamhi hwehwaro, chikamu: mita

Iyo yakasimbiswa kongiri hwaro inofanirwa kuve nechokwadi cheimwe nguva yekurapa iyo michina isati yave munzvimbo.

Kana ivhu rekamuri yemuchina riri pasi slab kana kongiri chimiro, hwaro hwechimiro chinoratidzwa mumufananidzo uri pazasi chinogona kugamuchirwa.Iyo kongiri nheyo 100mm ~ 200mm yakakwirira kupfuura pasi ichave yakabatana nepasi slab.Kubatana nefloor:

1.Kunyange welding nekusimbisa pasi.

2.Embedded bar welding.

3.Kuwedzera sikuruu welding.

Machine room ventilation system:

Kufefetedza kwekamuri yemuchina kunonyanya kupa mweya unotonhorera wakakwana kuti ubvise kupisa kweseti yejenareta, uye zvakare kupa mweya wakakwana wekupisa.Zvisinei, mhepo inoyerera inofanirawo kudzorwa kuitira kuti irege kukanganisa kunyaradza kwevashandi.

V = Vhoriyamu yekufema (m3/min)

H = Radiant kupisa kubva kujenareta yakaiswa kune muchina kamuri (kW), (Pa25 ℃, inogona kuwanikwa kubva kune tekinoroji parameter tafura)

Correction factor pane dzimwe tembiricha DCF = -.011* TER +1.3187 (TER = Chaiyo muchina tembiricha yemukamuri°C)

Kupisa Mhepo = Kupisa kudiwa kwemhepo (m3/min)

D = Kuwanda kwemhepo, 1.099 kg/m3 (38℃ 时）

CP = Mhepo chaiyo kupisa (0.017 kw* min/kg℃)

ΔT = Inobvumirwa tembiricha inokwira yekamuri yemuchina (° C) (Cherechedza: tembiricha yepamusoro yekamuri yemuchina ndeye 49 ° C)

F = Ventilation routing coefficient (sezvinoratidzwa mumufananidzo uri pazasi):

Nekuisirwa kwakabatanidzwa kweradiator uye injini, izvo zvinodikanwa zvekufemesa zvekamuri yemuchina ndizvo zvinotevera:

V = kuyerera kwemhepo yeradiator fan + kupisa kudiwa kwemhepo.

Iyo yekumashure kumanikidzwa kwemhepo inoyerera pakubuda kwetangi yemvura inotonhorera haipfuure 0.1275kPa.

Iyo nharaunda yeradiator yemhepo inovhara chivharo kazhinji yakakura ka1.5 pane iyo yeradiator musimboti.

Injini yekutonhora system:

Heat chiyero cheinjini system:

40%—Basa

30-40% - kupera mweya

20-40% - kutonhora

6-8% -Kukwenya uye nemwaranzi

Kupisa kunotorwa neinotonhodza system kunobva kune zvinotevera zvikamu zvitatu:

1.Cylinder liner water circuit

2.Lubricating mafuta inotonhorera

3.Turbocharger aftercooler

Main cooling circuit mode:

1.Separate kutonhodza dunhu (kureva imwe neimwe yeatatu ari pamusoro ekutonhodza masisitimu anoumba dunhu)

2.Hybrid cooling circuit (kureva kuti ari pamusoro apa matatu kana maviri masisitimu anoumba dunhu)

3.Air to air post post cooling circuit (kureva kuti mhepo inopisa kana turbocharging yatonhodzwa nemhepo yefeni)

Fomu yekutonhora system:

1.Open cooling system: kusanganisira kutonhora shongwe (pasina kupisa exchanger), spray pool uye yakawanda yemvura.(hazvikurudzirwi).

2.Yakavharwa kutonhora system: kusanganisira kutonhora shongwe (kusanganisira kupisa kupisa) kana fan radiator, kupisa kunopisa, evaporative inotonhorera, nezvimwe.

Kukamurwa kwema radiators:

1. Injini yakaiswa radiator.

2. Remote radiator: haifanire kunge iri 17.4 m yakakwirira kupfuura pombi yemvura yeinjini kudzivirira kubuda kunokonzerwa nekudzvinyirira kwakanyanya kunokuvadza chisimbiso chepombi yemvura.

Kana urefu uhwu hwapfuura, mutsinhanisi wekupisa unogona kushandiswa kana tangi yemvura yekushandura (inopisa tsime) inogona kuiswa munharaunda yekutenderera kwemvura.

Vertical kure kure radiator: iyo inotonhorera feni inovhuvhuta yakatwasuka.

Horizontal remote radio r: iyo inotonhorera fan inovhuvhuta kumusoro (teerera kudzivirira mvura, chando uye Frost).

Heat exchangers : shell uye chubhu uye ndiro.

Cooling tower:

Kana iyo yekutonhodza ichida tembiricha yakaderera (semuenzaniso, iyo post kutonhora wedunhu dzimwe nguva inoda 54 ℃ kana 32 ℃), inogona kutariswa kugadzira.

Shandisa shongwe yekutonhodza, kana kuda kushandisa mvura yerwizi, mvura yemudhamu yekutonhodza, nezvimwe.

Kune shongwe dzekutonhodza dzakavhurika uye dzakavharwa.

Pamusoro pechikamu 1 chekugadzira bhuku re best standby jenareta , nokuda kwenguva shoma, tinogona chete kugovera zvimwe zvikamu.Tichagovera chikamu 2 zuva rinotevera, ndapota tevera chinyorwa chedu chinotevera kuti uwane rumwe ruzivo nezve dhiziri jenareta kamuri.
