Indlela yokuqinisekisa uBomi beNkonzo yeCummins Supercharger

Ngenxa yokuba isantya sokusebenza esilinganisiweyo se-injini ye-Cummins supercharger ingaphezulu kwe-130,000 rpm, kwaye ikwindawo yokukhupha i-exhaust manifold, iqondo lobushushu liphezulu kakhulu (ngaphezu kwama-800 ° C), kwaye i-inlet kunye noxinzelelo lokuphuma likhulu, liphezulu. ubushushu, uxinzelelo oluphezulu kunye nesantya esiphezulu.Ngoko ke, iimfuno zokuthambisa, ukupholisa kunye nokutywinwa kwe-supercharger ziphezulu kakhulu.

Ukuze kuqinisekiswe ubomi benkonzo ye-supercharger ye Cummins generator injini , kuyimfuneko ukuqinisekisa ukuthambisa kunye nokupholisa kwe-turbocharger edadayo.Ngexesha elifanayo, ekusebenziseni, kuyafuneka ukuba:

a.I-injini kufuneka ingasebenzi imizuzu emi-3-5 emva kokuba iqalile.Musa ukongeza umthwalo ngokukhawuleza ukuqinisekisa ukuthambisa okulungileyo kwe-supercharger.Isizathu esiphambili kukuba i-supercharger ibekwe phezulu kwi-injini.Ukuba i-supercharger iqala ukusebenza ngesantya esiphezulu emva kokuba injini iqalile, oko kuya kubangela ukuba uxinzelelo lwe-oyile lusilele ukunyuka ngexesha lokubonelela nge-oyile kwi-supercharger, okukhokelela kumonakalo wokunqongophala kwe-oyile ye-supercharger, kunye nokutshisa yonke i-supercharger. .

b.Ixesha lokungasebenzi akufanele libe lide kakhulu, ngokubanzi lingabi ngaphezu kwemizuzu eyi-10.Ukuba ixesha lokungenzi nto lide kakhulu, kuya kubangela ukuvuza kweoyile ngokulula ekupheleni kwecompressor.

c.Musa ukuyicima i-injini ngoko nangoko phambi kokuba ime.Kufuneka ibe idling imizuzu emi-3-5 ukunciphisa isantya se-supercharger kunye nobushushu benkqubo yokukhupha ukushisa ukukhusela ukubuyiswa kobushushu-i-oyile yokupheka-i-oyile yokutshisa kunye nezinye iimpazamo.Ukusetyenziswa okungalunganga rhoqo kunokonakalisa i-supercharger.

d.Ii-injini ezingasetyenziswanga ixesha elide (ngokuqhelekileyo ngaphezu kweentsuku ezi-7), okanye iinjini ezineetshaja ezintsha, kufuneka zizaliswe ngeoli kwindawo yokungena ye-supercharger ngaphambi kokusetyenziswa, ngaphandle koko ubomi buya kuncitshiswa okanye i-supercharger yonakaliswe ngenxa yokungacoceki kakuhle.

e.Hlola rhoqo ukuba ngaba iinxalenye zokudibanisa zikhululekile, zivuza, ukuvuza kweoli, kunye nokuba umbhobho wokubuyisela awuphazamiseki, ukuba kukho, kufuneka ususwe ngexesha elifanelekileyo.

f.Gcina isihluzo somoya sicocekile kwaye rhoqo usibuyisele njengoko kufuneka.

g.Ukutshintsha rhoqo ioli kunye neoli yokucoca.

h.Rhoqo jonga i-radial axial clearance yeshaft ye-turbocharger.Ukukhutshwa kwe-axial akufanele kube ngaphezu kwe-0.15 mm.Ukukhutshwa kwe-radial kukuba: ukucocwa phakathi kwe-impeller kunye negobolondo yoxinzelelo akufanele kube ngaphantsi kwe-0.10 mm.Ngaphandle koko, kufuneka ilungiswe ngabachwephesha ukuphepha ilahleko.
