Chikamu 2: Mabasa eInjini Mafuta eCCEC Cummins Genset

Zvikamu zvinotevera zvinopihwa kune ruzivo rwakakwana.Kana oiri yeinjini ichiita zvakakwana, inofanirwa kuita zvinotevera mabasa:

Basa rekutanga remafuta einjini nderekuzora zvikamu zvinofamba zveinjini yedhiziri generator set . Oiri inoumba firimu rehydrodynamic pakati pesimbi.kudzivirira simbi - kusvika - simbi kusangana uye kuderedza friction.Kana iyo firimu yemafuta isina kukwana kudzivirira simbi - kune - metal kusangana, zvinotevera zvinoitika:

1. Kupisa kunogadzirwa kuburikidza nekukweshana.

2. Welding yemunharaunda inoitika.

3. Kutamisa simbi kunoguma nekukwenya kana kubata.

Yakanyanya Kudzvinyirira Wear Kudzora

Mafuta emazuva ano ane Extreme Pressure (EP) anti-wear additives.Izvi zvinowedzerwa zvinogadzira kemikari yakasungirirwa molecular firimu panzvimbo yesimbi pane yakanyanya kudzvanywa kudzivirira kubata zvakananga uye kupfeka kana mutoro pazvikamu wakakwira zvekubvisa iyo hydrodynamic firimu remafuta.

Kuchenesa

Oiri inoshanda semugadziri wekuchenesa muinjini nekutsvaira zvinosvibisa kubva kune zvakakosha zvinhu.Sludge, varnish uye oxidation buildup pamapistoni, zvindori, mavharuvhu stems, uye zvisimbiso zvinotungamira mukukuvadzwa kwakanyanya kweinjini kana ikasadzorwa nemafuta.Mafuta akagadzirwa neakanakisa ekuwedzera anozobata izvi zvinosvibisa zvimire kusvika zvabviswa neoiri filtration system kana panguva yekuchinja kwemafuta.

Dziviriro

Oiri inopa chipingamupinyi chinodzivirira, ichitsaura isina-yakafanana kudzivirira ngura.Corrosion sekupfeka mukubviswa kwesimbi kubva muzvikamu zveinjini.Corrosion inoshanda senge inononoka kuita kupfeka michina.

Kutonhodza

Injini dzinoda kutonhodzwa kwezvikamu zvemukati izvo yekutanga kutonhora system isingakwanise kupa.Mafuta ekuzora anopa yakanakisa kupisa kupisa svikiro.Kupisa kunoendeswa kuoiri kuburikidza nekusangana neyakasiyana-siyana, iyo inozoendeswa kune yekutanga kutonhora system pane inotonhorera oiri.

Kuisa chisimbiso

Oiri inoita sechisimbiso chinopisa ichizadza nzvimbo dzisina kuenzana dzecylinder liner piston, valve stem uye zvimwe zvinhu zvemukati injini.

Shock damping

Iyo firimu yemafuta pakati pekubata kumeso inopa cushioning uye kudenha kunotyisa.Iko kunyorovesa kwakakosha kunzvimbo dzakaremerwa zvakanyanya senge mabearings, pistons, tsvimbo dzekubatanidza uye chitima chegiya.

Hydraulic chiito

Oiri inoshanda senge inoshanda hydraulic media mukati meinjini.Mienzaniso yeizvi kushandiswa kweoiri kushandisa injini mabhureki uye STC injector tappets.

Mafuta anowedzera

Mafuta ekuzora anogadzirwa nezvinowedzerwa zvakagadzirirwa kurwisa zvakasvibiswa (zvakanyorwa muChikamu 6) mukati mehupenyu hwayo hunogona kushandiswa.Iwo ekuwedzera anoshandiswa anonyanya kukosha kune yakazara injini kuita pane iyo mafuta pachayo.Pasina zvinowedzera, kunyange iyo yepamusoro-soro oiri haizokwanisi kugutsa injini zvinodiwa.Additives zvinosanganisira:

1. Detergents kana dispersants, izvo zvinoramba zvisinganyunguriki zvakamiswa kusvikira mafuta achinjwa.Izvi zvakamiswa zvinhu hazvibviswe neoiri filtration system.Kunyanya kureba kwemafuta ekudonha kunokonzeresa kuumbwa kwedhipoziti muinjini.

2. Inhibitors inochengetedza kugadzikana kwemafuta, inodzivirira maasidhi kubva pakurwisa nzvimbo dzesimbi uye kudzivirira kuumbwa kwehutu kana injini isiri kushanda.

3. Zvimwe l mafuta ekuzora zvinowedzerwa zvinobatsira mafuta pakuzora nzvimbo dzakaremerwa kwazvo dzeinjini (senge mavharuvhu nechitima chejekiseni), kudzivirira kukwenya nekubata, kudzora kubuda furo uye kudzivirira kuchengetwa kwemhepo mumafuta.

Oiri yeinjini inofanirwa kugadzirwa nenzira yekuti haipuse furo semugumisiro weiyo mechanical agitation process ine chekuita nemabasa ayo akawanda.Oiri yakapupuma inokonzeresa kukuvadzwa kweinjini kwakafanana nekuziya kwemafuta, nekuda kwekusakwana kuchengetedza firimu remafuta.
