Isigaba sesi-2: Imisebenzi Yamafutha Enjini ye-CCEC Cummins Genset

Izigaba ezilandelayo zihlinzekelwe ngolwazi olujwayelekile.Uma uwoyela wenjini uzosebenza ngokwanele, kufanele enze imisebenzi elandelayo:

Umsebenzi oyinhloko wamafutha enjini ukugcoba izingxenye ezihambayo zenjini ye-diesel isethi yejeneretha . Amafutha akha ifilimu ye-hydrodynamic phakathi kwezindawo zensimbi.ukuvimbela ukuxhumana kwensimbi nokunciphisa ukungqubuzana.Lapho ifilimu yamafutha inganele ukuvimbela ukuxhumana kwensimbi kuya kwensimbi, okulandelayo kwenzeka:

1. Ukushisa kukhiqizwa ngokungqubuzana.

2. Welding Local kwenzeka.

3. Ukudluliswa kwensimbi kubangela ukugwaza noma ukubamba.

Ukulawula Ukugqoka Okucindezela Kakhulu

Izithambisi zesimanje ziqukethe izithasiselo zokulwa nokugqokwa kwe-Extreme Pressure (EP).Lezi zithasiselo zakha ifilimu yamangqamuzana ehlanganiswe ngamakhemikhali ezindaweni zensimbi ezicindezelwayo eziphakeme ukuvimbela ukuthintana okuqondile nokugqoka lapho umthwalo ezingxenyeni uphakeme ngokwanele ukuqeda ifilimu kawoyela we-hydrodynamic.

Ukuhlanza

Uwoyela usebenza njenge-ejenti yokuhlanza enjinini ngokukhipha ukungcola ezingxenyeni ezibalulekile.I-sludge, ivanishi kanye ne-oxidation buildup kuma-pistons, izindandatho, iziqu ze-valve, kanye nezimpawu kuzoholela ekulimaleni okukhulu kwenjini uma kungalawulwa uwoyela.Amafutha akhiwe ngezithasiselo ezifanele azobamba lokhu kungcola kumiswe okwesikhashana kuze kube yilapho esuswa uhlelo lokuhlunga uwoyela noma phakathi nokushintsha kukawoyela.

Ukuvikelwa

Uwoyela unikeza umgoqo ovikelayo, uhlukanise okungefani ukuze uvimbele ukugqwala.Ukugqwala njengokuguga ekukhishweni kwensimbi ezingxenyeni zenjini.I-Corrosion isebenza njengomshini wokugqoka osebenza kancane.

Ukupholisa

Izinjini zidinga ukupholiswa kwezingxenye zangaphakathi isistimu yokupholisa eyinhloko engakwazi ukukunikeza.Amafutha okugcoba ahlinzeka ngendlela enhle kakhulu yokudlulisa ukushisa.Ukushisa kudluliselwa emafutheni ngokuthintana nezingxenye ezihlukahlukene, ezibe sezidluliselwa ohlelweni oluyinhloko lokupholisa endaweni yokupholisa uwoyela.

Ukubeka uphawu

Amafutha asebenza njengophawu oluvuthayo olugcwalisa izindawo ezingalingani ze-cylinder liner piston, isiqu se-valve nezinye izingxenye zenjini zangaphakathi.

Ukuthuthumela kuyadambisa

Ifilimu kawoyela phakathi kwezindawo ezithintanayo inikeza i-cushioning kanye ne-shock damping.Umthelela wokudambisa ubalulekile ezindaweni ezilayishwe kakhulu njengama-bearing, ama-piston, izinduku zokuxhuma kanye nesitimela segiya.

Isenzo se-hydraulic

Amafutha asebenza njengemithombo ye-hydraulic esebenzayo ngaphakathi kwenjini.Izibonelo zalokhu ukusetshenziswa kwamafutha ukuze kusetshenziswe amabhuleki enjini kanye namatapethi omjovo we-STC.

Izithasiselo zamafutha

Amafutha okugcoba akhiwe ngezithasiselo eziklanyelwe ukulwa nokungcola okuthile (okusohlwini lweSigaba 6) kukho konke ukuphila kwawo okusebenzisekayo.Izithasiselo ezisetshenzisiwe zibaluleke kakhulu ekusebenzeni kwenjini iyonke kunowoyela uqobo.Ngaphandle kwezithasiselo, ngisho nowoyela wekhwalithi ephezulu kakhulu ngeke akwazi ukwanelisa izidingo zenjini.Izithasiselo zihlanganisa:

1. Izihlanzi noma izisabalalisi, ezigcina izinto ezingancibiliki zimisiwe kuze kushintshwe uwoyela.Lezi zinto ezimisiwe azisuswa uhlelo lokuhlunga uwoyela.Izikhawu ezinde kakhulu zokudonsa uwoyela ziphumela ekwakhekeni kwediphozithi enjinini.

2. Ama-inhibitors agcina ukuqina kwamafutha, avimbela ama-acids ekuhlaseleni izindawo zensimbi futhi avimbele ukwakheka kokugqwala lapho injini ingasebenzi.

3. Okunye l ubricating oil izithasiselo zisiza uwoyela ekugcobiseni izindawo zenjini ezigcwele kakhulu (njengamavalvu kanye nesitimela somjovo ), zinqande ukushwibeka nokubamba, zilawule ukukhihliza amagwebu futhi zinqande ukugcina umoya kuwoyela.

Amafutha enjini kufanele akhiwe ngendlela yokuthi angakhihlizi igwebu ngenxa yenqubo yokunyakaza kwemishini ehambisana nemisebenzi yawo eminingi.Uwoyela onegwebu uphumela ekulimaleni kwenjini okufana nendlala kawoyela, ngenxa yokuvikelwa kwefilimu kawoyela okwanele.
