Kushandiswa kweTekinoroji Yekuchengetedza Mafuta Kune Majenareta eDiesel

5) Chengetedza jekiseni mberi Angle ye dhiziri jenareta

Diesel jenareta inonzwa zvakanyanya kune jekiseni mberi kweAngle, saka iyo jekiseni yenguva mucherechedzo wedhiziri jenareta inomakwa paflywheel uye jekiseni pombi.Iva nechokwadi chekuenzanisa zviratidzo paunenge uchiverenga.Nekudaro, nekuda kwekupfeka uye deformation yezvikamu zvekutapurirana, iko kurongeka kwejekiseni nguva kunokanganisa.Naizvozvo, zvinodikanwa kuitisa bvunzo bvunzo kururamisa mushure mekuongorora kuti ive nechokwadi chekuti simba rejenareta seti rakakwana uye kwete rough.

6) Ita shuwa kuvharwa kwedhiziri jenareta jekiseni jekiseni pombi plunger

7) Bvisa zvikanganiso zvinotevera zvemajenareta edhiziri:

Bvisa zvikanganiso zvinotevera nenguva.Dzivisa dhiziri jenareta utsi, kugogodza uye kusagadzikana kushanda kwechinhu chisingadikanwi.

Kushaikwa kwemhepo nekuda kwekuvharika kwesefa yemhepo.

Low jekiseni pressure.Hunhu husina kunaka hwejekiseni.Kukonzera yakaipa mafuta atomization.

Injector inodonha mafuta.

Jekiseni nekukurumidza kana kunonoka.

Jekiseni remafuta rakawandisa.

8) Simbisa kucheneswa kwemafuta edhiziri jenareta

Inopfuura hafu ye diesel jenareta kutadza kuri mumafuta ekupa system.Mhinduro ndeyekutenga mafuta edhiziri kwemazuva 2-4 uye wozoshandisa.91% - 98% yetsvina inogona kudonha.Kana ukachitenga iko zvino, isa mitsara miviri yejira resirika kana bepa rechimbuzi pasefa yetangi remafuta rejenareta redhiziri.Inogona kusefa dhayamita inodarika 0. OOlmm tsvina.

9) Kusarudzwa kwakaringana kwedhiziri jenareta mafuta emafuta uye mafuta ekuzora

Diesel mafuta akanyorwa nechando.Mafuta edhiziri akareruka anogadzirwa muChina haana.0, kwete.10, No. 20 neNo. 35 (chando chiri 0 ℃, -10 ℃, -20 ℃ uye -35 ℃ zvichiteerana. Kuti uve nechokwadi chekupihwa kwemafuta anotsvedzerera, tembiricha yepakati inofanira kunge iri 5 ℃ yakakwirira kupfuura nzvimbo yechando. .

Iyo viscosity yemafuta edhiziri inofanirwawo kuve yakakodzera, iyo viscosity yakanyanya, kuitira kuti atomization iite zvishoma, kupisa hakuna kuchengetedzeka, pombi yekupedza inoburitsa utsi hwakasviba, kushandiswa kwemafuta kunowedzera.Zvinoenderana nebvunzo: zvichienzaniswa neyakajairika viscosity yakapetwa kaviri, kushandiswa kwemafuta kwakawedzera 15g/(KWH).Asi iyo viscosity yakadzikira, kubuda kwemafuta ejekiseni pombi plunger kunowedzera, iyo plunger lubrication inova isina kunaka, uye kupfeka kwakakomba, saka viscosity yemafuta edhiziri inofanirwa kudzorwa mumhando yakakodzera.

The compression reshiyo uye kupisa mutoro wejenareta dhiziri yakakwirira kwazvo kupfuura iyo yeinjini yepeturu, uye kukora kwedhiziri kwakakura kupfuura iyo peturu, saka jenareta redhiziri rinoshandisa mafuta ekuzora epamusoro ane zvinowedzera.

Cummins Chigadzirwa chekuita maitiro:

Compact dizeli jenareta set

Belt drive system: ine otomatiki tensioning michina, kuitira kuti bhandi risachengetedzwe

Kubatanidza tsvimbo: Forged yekubatanidza tsvimbo ine yakanyanya kusimba simba

Crankshaft: Induction yakadzima simbi crankshaft kune yakanyanya simba uye akawanda kudzokorora kugona

Cylinder block: Iyo nyowani yepamusoro-simba dhizaini inowedzera kuomarara kwecylinder block ne32%, ichipa kusimba kwakanyanya.

Cylinder liner: Patented stopper dhizaini yekuomarara liner uye yakawedzera piston hupenyu hwemhete.

Fuel system: Bosch mhando in-line plunger kana rotor yakakwira kumanikidza pombi uye majekiseni ehupfumi hwemafuta huri nani.

Turbocharger: Holset turbocharger, HX40 mhando ine yakakosha kupera gasi bypass valve, inowedzera kunatsiridza kuderera kwekuita uye kushanda kwesimba.

Mapistoni: Aluminium alloy pistons ane maviri asingadziviriri epamusoro nickel cast iron ring grooves anowedzera piston uye hupenyu hwemhete, uye anodized piston tops anobatsira kuvandudza kusimba.

Oiri sefa: yakasanganiswa yakazara kuyerera uye bypass Frejag brand, kusefa mhedzisiro inenge yakakwana, inovandudza kusimba kweiyo switchboard.
