Ukuhlolwa kunye noTshintsho lomlomo wesitofu

Ukudityaniswa kwevalve yenaliti ikwabizwa ngokuba luqhagamshelo lombhobho we-injector.Yenziwe ngevalve yenaliti kunye nomzimba wevalve yenaliti ukwenza ukudibanisa okuchanekileyo.Emva kokuba igutywe ngababini, ayitshintshi.Impazamo enkulu yendibano yevalve yenaliti kukuba umngxuma womlomo uvalekile kwaye isitywina asiqinile.

1 Indlela yovavanyo lobugcisa

(1) Indlela yokujonga ngaphandle.Ubume bobugcisa bendibano ye-injector ye-fuel inokugwetywa kumgangatho we-atomization yamafutha.Emva kokulungelelanisa uxinzelelo lwenaliti, xa kukho amabala enkungu okanye imigca yeoli enobunzima obungalinganiyo kwisitshizi, ngokuqhelekileyo sisitofu se-fuel.I coupler inxitywe kakhulu;xa inkungu yeoli isasazwa ngokungafaniyo okanye umgca ophakathi womgca weoyile uphikisiwe, ubonisa ukuba umngxuma we-nozzle awucocekanga;xa kukho ioli ethontsizayo emva kokutshiza, oko kuthetha ukuba ikhowuni yokutywina yevalve yenaliti ayivalwanga ngokuqinileyo.

(2) Uvavanyo lokutywina.Lungisa i-injection ye-fuel injector ye-fuel injector ibe yi-3-5MPa ephezulu kunoxinzelelo oluqhelekileyo, kwaye ukhangele ixesha elidlulayo xa i-fuel pressure yehla ukusuka kwi-20Pa ukuya kwi-18Pa, engafanele ibe ngaphantsi kwe-9-12s.

2 Imiqathango yokutshintshwa

Ukutshintshwa kwendibano ye-injector kufuneka kuqhutywe ngolu hlobo kunye nendlela elandelayo: (1) Susa i-cap ye-injector kunye ne-lock nut, kwaye ukhulule i-screw yokulungelelanisa.(2) Khupha intwasahlobo, isihlalo se-spring kunye ne-ejector pin ngokulandelelana.(3) Gxininisa indawo yokuhlala yesitofu samafutha kwi-vise, khulula ikepusi eqinileyo yesitofu samafutha, kwaye ususe isitofu samafutha.4Kuyimfuneko ukuba intonga ye-ejector ayigobekanga, ibhola yensimbi ye-ejector intonga ayijikelezi okanye ihlulwe, kwaye iindawo zokudibanisa zegobolondo zihamba kakuhle kwaye zingenawo amanqaku okugqwala.(5) Gubha i-oyile entsha yesitofu se-fuel kwi-oyile ye-diesel ukususa i-oyile enqanda umhlwa kwaye wenze indlela ye-oyile, umlomo kunye negumbi le-oyile lingavalwa.(6) Izinyuko zendibano zichasene nezo disassembly.Xa ufaka indibano ye-injector, ayivumelekanga ngokupheleleyo ukuba iqhutywe phantsi koxinzelelo lwentwasahlobo.(7) Qinisa ikepusi ngokwetorque echaziweyo, emva koko ubeke intonga ye-ejector, isihlalo sasentwasahlobo, kunye noxinzelelo olulawula intwasahlobo kwiqokobhe ngokutshintshana, kwaye ujije isikrufu sokulungisa.Lungisa uxinzelelo kwi-nozzle tester, kwaye emva koko utshixe ikepusi eqinileyo emva kokuphumelela uvavanyo.
