Impompi yokutofa iFuel 3975701/4941066/4988593/0445020122/0445020043 Foton Isf3.8 Amacandelo eNjini

Iindlela zogcino lwempompo yokutofa kwe-injini ye-diesel

(5) Jonga ukucocwa kwecamshaft rhoqo
Ukukhutshwa kwe-axial ye-camshaft yempompo yokutofa kwamafutha kungqongqo kakhulu, ngokubanzi phakathi kwe-0.03 kunye ne-0.15mm. Ukuba ukucocwa kukhulu kakhulu, impembelelo yeengxenye zokuhambisa i-roller kwindawo yokusebenza yekhamera iya kuba nzima, ngaloo ndlela ikhulise ukunxiba kwangaphambili kwendawo yekhamera kunye nokutshintsha i-oil supply angle advance; Ukukhutshwa okugqithisileyo kwe-axial kunye neradial clearance yeebheringi zecamshaft ngokulula kunokubangela ukuba icamshaft iqhube ngokungazinzanga, intonga yohlengahlengiso lobungakanani be-oyile ingcangcazele, kunye nobungakanani bokubonelela ngeoyile ukuba butshintshe ngamaxesha athile, nto leyo eyenza ukuba injini yedizili iqhube ingazinzanga. Ngoko ke, kuyimfuneko ukujonga rhoqo kunye noLungiso. Xa ukukhutshwa kwe-axial ye-camshaft kukhulu kakhulu, kunokulungelelaniswa ngokongeza i-shims kumacala omabini; xa ukukhutshwa kwe-radial kukhulu kakhulu, ngokuqhelekileyo kuyimfuneko ukuyibuyisela entsha.

(6) Jonga rhoqo imeko yokutywinwa kwendibano yevalve yeoyile kumatshini
Emva kokuba impompo yokutofa kwepetroli isebenze ixesha elide, isigwebo esiqatha sinokwenziwa ekunxityweni kweplunger kunye nemeko yokusebenza yempompo yamafutha ngokujonga imeko yokutywinwa kwevalve yokukhupha amafutha, enenzuzo ukumisela. iindlela zokulungisa kunye nokugcina. Ngethuba lokuhlola, khulula i-oyile ye-high-pressure joints of cylinder nganye, kunye ne-oyile yepompo kunye nempompo ye-oyile yesandla yepompo yokuhambisa ioli. Ukuba kukho i-oyile ephumayo kumbhobho we-oyile kumphezulu wempompo yokutofa ngamafutha, oko kuthetha ukuba ivalve yokuphuma kwe-oyile ayivalwanga kakuhle (kakade, iya konakaliswa xa isibonda sevalvu yokuphuma kwe-oyile saphukile. imeko iyenzeka). Ukuba kukho ukutywinwa okungahambi kakuhle kweesilinda ezininzi, impompo yokutofa ngamafutha kufuneka icocwe kwaye igcinwe, kwaye iindawo ezilinganayo kufuneka zitshintshwe.
