Icandelo 2: Imisebenzi ye-Oli ye-Engine ye-CCEC Cummins Genset

La macandelo alandelayo abonelelwe ngolwazi ngokubanzi.Ukuba i-oyile ye-injini kufuneka isebenze ngokufanelekileyo, kufuneka yenze le misebenzi ilandelayo:

Umsebenzi ophambili we-oyile ye-injini kukuthambisa iindawo ezihambayo ze-injini ye-diesel iseti yejenereyitha . Ioyile yenza ifilimu ye-hydrodynamic phakathi kwemigangatho yesinyithi.ukuthintela isinyithi - ukuya ku-metal contact kunye nokunciphisa ukukhuhlana.Xa ifilimu yeoli ingonelanga ukukhusela isinyithi ukuya kwintsimbi, oku kulandelayo kwenzeka:

1. Ubushushu buveliswa ngokukhuhlana.

2. I-welding yendawo iyenzeka.

3. Ukudluliselwa kwesinyithi kubangela ukukhuhla okanye ukuhlutha.

Ulawulo lokuNxitywa koxinzelelo olugqithisileyo

Izithambisi zale mihla zinezongezo ezichasene nokunxitywa koxinzelelo olugqithisileyo (EP).Ezi zongezo zenza ifilimu yemolekyuli ebopheleleke kwimichiza kwindawo yentsimbi kuxinzelelo oluphezulu ukuthintela ukunxibelelana ngokuthe ngqo kunye nokunxiba xa umthwalo kumalungu uphezulu ngokwaneleyo ukuphelisa ifilimu yeoli ye-hydrodynamic.

Ukucoca

I-oyile isebenza njenge-arhente yokucoca kwi-injini ngokugungxula izinto ezingcolileyo ezivela kwizinto ezibalulekileyo.I-Sludge, ivanishi kunye ne-oxidation buildup kwiipiston, imisesane, iziqu zevalve, kunye ne-seals ziya kukhokelela kumonakalo omkhulu we-injini ukuba awulawulwa yi-oyile.I-oyile eyenziwe ngezongezo ezifanelekileyo iya kubamba ezi zingcolisi ekumisweni zide zisuswe yinkqubo yokucoca ioli okanye ngexesha lokutshintsha kweoli.

Ukhuseleko

Ioyile ibonelela ngomqobo okhuselayo, ukwahlula okungafaniyo nokuthintela ukubola.Ukonakala njengokuguga ekukhutshweni kwentsimbi kumalungu enjini.Ukonakala kusebenza njengesixhobo sokunxiba esicothayo.

Ukupholisa

Iinjini zifuna ukupholisa kwamalungu angaphakathi ukuba inkqubo yokupholisa ephambili ayinako ukubonelela.I-oyile yokuthambisa ibonelela ngendlela ebalaseleyo yokudlulisa ubushushu.Ubushushu bukhutshelwa kwi-oyile ngokudibana namalungu ahlukeneyo, athi ke adluliselwe kwisixokelelwano sokuqala sokupholisa kwi-oyile yokupholisa.

Ukutywinwa

I-oyile isebenza njengetywina lokutsha elizalisa iindawo ezingalinganiyo zepiston ye-cylinder liner, i-valve stem kunye nezinye izinto zangaphakathi ze-injini.

Umothuko uyadambisa

Ifilimu yeoli phakathi kweendawo zokunxibelelana ibonelela nge-cushioning kunye ne-shock damping.Umphumo wokudambisa ubalulekile kwiindawo ezilayishwe kakhulu ezifana neebheringi, iipistoni, iirodi zokudibanisa kunye nololiwe wegiya.

Isenzo se-hydraulic

I-oyile isebenza njengesixhobo sosasazo lwe-hydraulic ngaphakathi kwe-injini.Imizekelo yoku kukusetyenziswa kwe-oyile ekusebenziseni iziqhoboshi ze-injini kunye neetapethi zokutofa ze-STC.

Izongezo zeoyile

Ioli yokuthambisa iqulunqwe kunye nezongezo ezenzelwe ukulwa nezingcolisi ezithile (ezidweliswe kwiCandelo lesi-6) kubo bonke ubomi bayo obusebenzisekayo.Izongezo ezisetyenzisiweyo zibaluleke ngakumbi ekusebenzeni kwe-injini iyonke kuneoyile ngokwayo.Ngaphandle kwezongezo, neyona oyile ikumgangatho ophezulu ayinakukwazi ukwanelisa iimfuno zenjini.Izongezo ziquka:

1. I-detergents okanye i-dispersants, ezigcina izinto ezingenayo i-insoluble ekumisweni de ioli iguqulwe.Ezi zinto zimisiweyo azisuswanga yinkqubo yokucoca ioli.Amathuba amade ngokugqithisileyo e-oyile aphumela ekwenziweni kwediphozithi enjinini.

2. Ii-inhibitors ezigcina ukuzinza kweoli, zithintela i-acids ekuhlaseleni iindawo zetsimbi kwaye zithintele ukubunjwa kwe-rust xa injini ingasebenzi.

3. Okunye l ubricating ioli izongezo zinceda i-oyile ekuthambiseni iindawo ezithwele kakhulu injini (ezifana neevalvu kunye ne-injector train) , zithintele ukukrwaqula nokubamba, zilawule ugwebu kwaye zithintele ukugcinwa komoya kwi-oyile.

I-oyile ye-injini kufuneka yenziwe ngendlela yokuba ingabi namagwebu ngenxa yenkqubo yokuphazamiseka koomatshini eyayanyaniswa nemisebenzi yayo emininzi.I-oyile enegwebu ibangela umonakalo we-injini ofana nendlala yeoli, ngenxa yokungonelanga kokhuselo lwefilimu yeoli.
