Gawo 2: Ntchito za Engine Mafuta a CCEC Cummins Genset

Magawo otsatirawa aperekedwa kuti mudziwe zambiri.Kuti mafuta a injini agwire bwino ntchito, ayenera kuchita izi:

Ntchito yayikulu yamafuta a injini ndikupaka magawo osuntha a injini ya dizilo generator set . Mafutawa amapanga filimu ya hydrodynamic pakati pa zitsulo.kuteteza kukhudzana kwachitsulo ndi zitsulo ndikuchepetsa kukangana.Pamene filimu yamafuta sikwanira kuteteza kukhudzana kwachitsulo ndi zitsulo, zotsatirazi zimachitika:

1. Kutentha kumapangidwa chifukwa cha kukangana.

2. kuwotcherera m'deralo kumachitika.

3. Kusintha kwachitsulo kumabweretsa scuffing kapena kulanda.

Kuwongolera Kuthamanga Kwambiri Kwambiri

Mafuta odzola amakono amakhala ndi zowonjezera zoletsa kuvala za Extreme Pressure (EP).Zowonjezera izi zimapanga filimu yomangika ndi mamolekyu pazitsulo zachitsulo pazovuta kwambiri kuti ziteteze kukhudzana ndi kuvala pamene katundu pazigawozo ndi wokwanira kuthetsa filimu yamafuta a hydrodynamic.

Kuyeretsa

Mafuta amagwira ntchito ngati choyeretsera mu injini pochotsa zonyansa kuchokera kuzinthu zofunika kwambiri.Sludge, varnish ndi oxidation buildup pa pisitoni, mphete, valavu zimayambira, ndi zosindikizira zidzabweretsa kuwonongeka kwakukulu kwa injini ngati sikuyendetsedwa ndi mafuta.Mafuta opangidwa ndi zowonjezera zowonjezera amasunga zonyansazi kuyimitsidwa mpaka zitachotsedwa ndi makina osefera mafuta kapena panthawi yakusintha kwamafuta.

Chitetezo

Mafuta amapereka chotchinga choteteza, kudzipatula osafanana kuti ateteze dzimbiri.Kuwonongeka ngati kuvala pakuchotsa zitsulo ku magawo a injini.Kuwonongeka kumagwira ntchito ngati njira yovala pang'onopang'ono.

Kuziziritsa

Injini zimafunikira kuziziritsa kwazinthu zamkati zomwe makina ozizirira oyambira sangathe kupereka.Mafuta opaka mafuta amapereka njira yabwino kwambiri yotumizira kutentha.Kutentha kumasamutsidwa ku mafuta pokhudzana ndi zigawo zosiyanasiyana, zomwe zimasamutsidwa kumalo oyambirira ozizira ozizira pa mafuta ozizira.

Kusindikiza

Mafuta amakhala ngati chisindikizo choyaka moto chomwe chimadzaza malo osagwirizana a cylinder liner piston, tsinde la valve ndi zida zina zamkati za injini.

Shock damping

Filimu yamafuta pakati pa malo olumikizirana imapereka kutsitsa komanso kutsitsa.Mphamvu yonyowa ndiyofunikira kumadera odzaza kwambiri monga ma fani, ma pistoni, ndodo zolumikizira ndi sitima yamagetsi.

Zochita za Hydraulic

Mafuta amagwira ntchito ngati ma hydraulic media mkati mwa injini.Zitsanzo za izi ndikugwiritsa ntchito mafuta poyendetsa mabuleki a injini ndi matepi ojambulira a STC.

Mafuta owonjezera

Mafuta opaka mafuta amapangidwa ndi zowonjezera zomwe zimapangidwira kuti zithetse zowonongeka (zomwe zalembedwa mu Gawo 6) pa moyo wake wonse.Zowonjezera zomwe zimagwiritsidwa ntchito ndizofunikira kwambiri pakuchita bwino kwa injini kuposa mafuta omwewo.Popanda zowonjezera, ngakhale mafuta apamwamba kwambiri sangathe kukwaniritsa zofunikira za injini.Zowonjezera zikuphatikizapo:

1. Detergents kapena dispersants, zomwe zimasunga zinthu zosasungunuka mpaka mafuta atasinthidwa.Zida zoyimitsidwazi sizimachotsedwa ndi makina osefera mafuta.Kutaya mafuta kwanthawi yayitali kumapangitsa kuti injiniyo isungidwe.

2. Zoletsa zomwe zimasunga kukhazikika kwa mafuta, zimalepheretsa ma asidi kuti asawononge malo azitsulo ndikuletsa kupanga dzimbiri pamene injini sikugwira ntchito.

3. Zina l mafuta odzola zowonjezera zimathandizira mafuta kuti azipaka malo odzaza kwambiri a injini (monga mavavu ndi njanji ya jekeseni), kuteteza kusweka ndi kugwira, kuwongolera kutuluka thovu ndikuletsa kusungidwa kwa mpweya mumafuta.

Mafuta a injini amayenera kupangidwa m'njira yoti samatulutsa thovu chifukwa cha kusokonezeka kwamakina komwe kumayenderana ndi ntchito zake zambiri.Mafuta a thovu amabweretsa kuwonongeka kwa injini mofanana ndi njala yamafuta, chifukwa chosakwanira kuteteza filimu yamafuta.
