Mosi oa Exhaust System le Fuel System ea jenereithara ea China

1.Mosi oa ho ntša mosi

Sebopeho sa sistimi:

Haholo-holo e kenyelletsa mefuta e mengata ea ho ntša metsi, turbocharger, bellows, pipe ea ho ntša mosi, silencer, joalo-joalo.

1.1 Khokahano e bonolo ea exhaust.

Arola boima ba phala ea ho ntša metsi e sebelisoang ho enjene 'me u monye ho sisinyeha ha likarolo tsa sistimi ea ho tsoa.

1.2.Mothodisi

Mofuta oa indasteri (ho theoha ha lerata 12-18 dB)

Mofuta oa bolulo (lerata le theoha 18-25 dB)

Mofuta o phahameng oa ts'ebetso (lerata le theoha 25-35 dB)

1.3.Peipi ea ho ntša mosi

Se ke oa feta khatello e lumelletsoeng ea ho ntša metsi ka morao ea enjene.Feteletseng exhaust back pressure e tla ama ts'ebetso ea enjene, e fokotse matla a enjene le ho eketsa tšebeliso ea mafura, mocheso oa ho tima le ho tsoa.Ka kakaretso, khatello ea morao ea tsamaiso ea ho qeta nako e ka tlaase ho halofo ea boleng bo phahameng bo amohelehang.

Arola bonyane 229mm ho tsoa linthong tse ka chesoang.

Qetello ea phala ea ho ntša mosi e khaotsoe ka mokhoa oblique ka lehlakoreng la 30 ° ho isa ho 45 °.

Thibela metsi a pula ho kena tsamaisong ea liphaephe.

1.4.Tekanyo ea khatello ea morao ea ho tsoa.

Hangata, khatello ea morao ea ho tima e lekantsoe ka moroalo o felletseng le lebelo le lekantsoeng la enjene.

Palo ea khatello ea morao ea exhaust

P=khatello ea morao (KPa)

L=bolelele ba peipi ya ho tima (m)

S=Boemo ba moea (kg/m3)

Q=Ho phalla ha khase (m3/min)

D=Karolo e ka hare ea phala (mm)

Ps=Ho theoha ha khatello ea silencer / sekoaelo sa pula (kPa)

2. Tsamaiso ea mafura

Ka kakaretso, sistimi ea phepelo ea mafura e na le sistimi ea polokelo ea mafura, sistimi ea phepelo ea mafura le sistimi ea ho hloekisa mafura.

2.1.Tanka ea polokelo ea mafura a diesel (tanka e kholo)

Tanka e kholo ke tanka e kholo ea ho boloka mafura.Mafura a tsamaisoa ho tloha tanka e kholo ho ea tanka e nyenyane ea thuso kapa ka ho toba ho enjene.

Tanka ea oli e tlameha ho finyella litlhoko tse latelang:

Sebelisa tšepe e tlaase ea carbon kapa lisebelisoa tse ntšo tsa tšepe.Qoba manonyeletso a masenke, liphaephe le litanka tsa oli.

Tanka ea oli e ka kenngoa ka holimo kapa ka tlas'a mobu, empa boemo bo phahameng ba oli ha boa lokela ho feta bophahamo ba enjene ea enjene.Sena se ka qoba monyetla oa ho lutla ha mafura ho silindara.

Netefatsa hore metsi le sediment li lula li tsoa ka tlase ho tanka.

Bakeng sa tanka ea oli e kentsoeng ka tlas'a fatše, pompo ea metsi e ka sebelisoa ho ntša metsi ho tloha tlaase ho tanka ea oli kamehla.

Setsi sa tanka se ka lokolla khatello ea moea e hlahisoang ke ho tlatsa mafura le ho thibela vacuum nakong ea tšebeliso ea mafura.

2.2.Tanka e thusang ea mafura (kapa tanka ea letsatsi le letsatsi ea mafura)

Tanka ea oli e thusang e hloka ho eketsoa maemong a latelang.

Tanka e kholo ea oli e behiloe ho feta 3.7m ka tlase ho pompo ea mafura ea enjene.

Tanka e kholo ea oli e behiloe ho feta 15m hole le enjene.

Bophahamo ba tanka e kholo bo feta bophahamo ba enjene ea enjene.

2.3.Peipi ea mafura

Pipe ea mafura e lokela ho etsoa ka tšepe e ntšo.Leha ho le joalo, bakeng sa liphaephe tse nyenyane tsa oli tse bophara ba liphaephe tse ka tlaase ho 13mm, lipeipi tsa koporo li ka sebelisoa ho e-na le hoo.Li-valve le likhokahano li ka etsoa ka tšepe kapa boronse.U se ke ua sebelisa koporo (hobane e na le zinki).

Peipi ea mafura e tla kengoa hole le mehloli ea mocheso (joalo ka manifold exhaust le turbocharger) ho qoba ho futhumala ho feteletseng ha mafura le likotsi tse ka bang teng.Mocheso o moholo o kenang mocheng oa peterole oa enjene o ke ke oa feta 66 ° C. e 'ngoe le e' ngoe ea 6 ° C ka holimo ho boleng ba mocheso ona o tla fokotsa matla ka 1%.

Li-valve li se ke tsa sebelisoa pompong ea ho khutlisa mafura ho qoba tšenyo ea sefe ea mafura.Peipi e khutlisetsang oli e tla kena ka holim'a tanka.

Khokahano e bonolo e tla amoheloa lipakeng tsa enjene, peipi ea mafura le tanka ea oli ho arola ho thothomela.

Bophara ba liphaephe tse kenang le tse khutlang ha lia lokela ho ba ka tlase ho boholo bo lumellanang ba enjene.

Boemo ba ho kenya tanka ea oli e thusang bo tla etsa hore boemo bo phahameng ba oli ba tanka ea oli bo be tlase ho feta bophahamo ba molomo oa enjene ea mafura, e le ho qoba monyetla oa ho lutla ha mafura ho silindara nakong ea ho koala.

Khatello ea ka ntle sebakeng sa ho khutlisa mafura a enjene ha ea lokela ho feta 27kpa.

2.4.Tanka e tlase ea mafura ea jenereithara ea diesel

Tlhophiso e tloaelehileng ea letoto la Dingbo Power jenereithara ea matla e khutsitseng ka matla a ka tlase ho 440kw ke tanka ea mafura e ka sebelisoang lihora tse 8 tsa ts'ebetso e felletseng ea yuniti, e ka tlas'a setsi sa jenereithara mme e kentsoe sete e felletseng pele e tloha fekthering.

2.5. Sebaka sa tanka ea mafura

Bakeng sa ho ntlafatsa polokeho ea basebetsi le ho thibela mollo o bakoang ke tlhase e ka hare ea motlakase nakong ea ho tlatsa mafura, tanka e kholo ea oli le tanka ea oli e thusang li tlameha ho theoa.Tanka ea oli ea motheo e ka thehoa ka sete ea jenereithara.

3. Motlakase le tsamaiso ea taolo

Bakeng sa ho netefatsa mabone, moea le tšebeliso ea matla ea lisebelisoa tse thusang tsa jenereithara ka phaposing ea mochini, ho tlameha ho fanoe ka sistimi e ikemetseng ea taolo ea motlakase.

Matla le mabone a kamore ea mochini a amohela moralo oa ho fetola matla a mabeli.

Boloka matla a terata ea 380V ea mekhahlelo e meraro, 'me u bale matla ho latela lisebelisoa tse hlokahalang.

Mokhoa o tsoang oa jenereithara: thapo kapa khokahano ea bese, le tataiso e tsoang e ka khethoa kamoo ho hlokahalang.

Mohala oa taolo ea yuniti: modbus, mohala oa lets'oao la ho qala le mohala oa lets'oao la sistimi e ts'oanang.

Mohlomong u boetse u rata sengoloa se ka tlase:

Mokhoa oa ho kenya Tanka ea Mafura ea Sete ea Jenereithara ea Dizeli

Tsebo ea ho Pholosa Mafura ea Sete ea Jenereithara ea Dizeli
