Ungayiqinisekisa Kanjani Impilo Yesevisi Ye-Cummins Supercharger

Ngenxa yokuthi isivinini esilinganiselwe sokusebenza se-supercharger yenjini ye-Cummins singaphezu kuka-130,000 rpm, futhi isendaweni lapho kuphuma khona amandla amaningi, izinga lokushisa liphezulu kakhulu (ngaphezu kuka-800°C), kanti ne-inlet ne-exhaust pressure nayo inkulu, iphakeme. izinga lokushisa, umfutho ophezulu kanye nesivinini esikhulu.Ngakho-ke, izidingo zokugcoba, ukupholisa kanye nokufaka uphawu kwe-supercharger ziphakeme kakhulu.

Ukuze uqinisekise impilo yesevisi ye-supercharger ye Cummins injini generator , kuyadingeka ukuqinisekisa ukugcotshwa nokupholisa kwe-turbocharger ezintantayo.Ngesikhathi esifanayo, ukusetshenziswa kuyadingeka:

a.Injini kufanele ingasebenzi imizuzu engu-3-5 ngemva kokuqala.Ungangezi umthwalo ngokushesha ukuze uqinisekise ukugcoba okuhle kwe-supercharger.Isizathu esikhulu ukuthi i-supercharger itholakala phezulu enjinini.Uma i-supercharger iqala ukusebenza ngesivinini esikhulu ngokushesha ngemva kokuba injini iqalile, kuyobangela umfutho kawoyela ukuba wehluleke ukukhuphuka ngesikhathi ukuze unikeze uwoyela emshinini wokushaja, okuholela ekulimaleni kokushoda kwamafutha e-supercharger, futhi kushise ngisho ne-supercharger yonke. .

b.Isikhathi sokungenzi lutho akufanele sibe side kakhulu, ngokuvamile singabi ngaphezu kwemizuzu eyi-10.Uma isikhathi sokungenzi lutho siside kakhulu, sizobangela kalula ukuvuza kwamafutha ekugcineni kwe-compressor.

c.Ungayivali injini ngokushesha ngaphambi kokuma.Kufanele ibambe imizuzu emi-3-5 ukuze kuncishiswe ijubane le-supercharger kanye nezinga lokushisa le-exhaust system ukuze kuvinjwe ukubuyiswa kokushisa—i-coking kawoyela—ukuvutha okuthwalayo namanye amaphutha.Ukusebenzisa okungalungile njalo kungalimaza ishaja enkulu.

d.Izinjini ezingasetshenziswa isikhathi eside (ngokuvamile ezingaphezu kwezinsuku ezingu-7), noma izinjini ezinamashaja amasha, kufanele zigcwaliswe ngamafutha endaweni yokungena yeshaja ngaphambi kokusetshenziswa, ngaphandle kwalokho ukuphila kungase kuncishiswe noma ishaja enkulu ilimale ngenxa yokungagcobi kahle.

e.Hlola njalo ukuthi izingxenye zokuxhuma zikhululekile yini, ziyavuza, zivuza uwoyela, nokuthi ipayipi elibuyayo alivimbekile yini, uma likhona, kufanele lisuswe ngesikhathi.

f.Gcina isihlungi somoya sihlanzekile futhi usishintshe njalo njengoba kudingeka.

g.Shintsha njalo isihlungi sikawoyela namafutha.

h.Hlola njalo i-radial axial clearance ye-turbocharger shaft.Ukucaciswa kwe-axial akufanele kube ngaphezu kuka-0.15 mm.I-radial clearance iwukuthi: imvume phakathi kwe-impeller negobolondo lokucindezela akufanele ibe ngaphansi kuka-0.10 mm.Uma kungenjalo, kufanele ilungiswe ochwepheshe ukugwema ukulahlekelwa.
