Isitofu se-Diesel se-Fuel Injector 0445120254 Bosch

Ukuhlolwa kunye nokulungiswa komkhono we-injector plunger

(1) Qwalasela ukukrazuka kumngxuma womkhono weplunger wesitofu sesibaso. Ukuba i-injector iphumelele uvavanyo lwe-tightness kwi-tester, ngoko umkhono we-plunger uyafumaneka. Ukuba ukuvuza kukhulu, umkhono weplunger kunye neplunger kufuneka kutshintshwe.

(2) Sebenzisa iglasi yokukhulisa amandla aphezulu ukujonga i-burr, i-carbon accumulation kunye ne-deformation kumngxuma wokulinganisa. Xa umngxuma wokulinganisa wonakalisiwe, i-fuel injector ayikwazi ukusebenza ngokuqhelekileyo. Ungazami ukucoca ngocingo lwensimbi, i-plug gauge, njl., kufuneka isebenzise ukucoca i-solvent.

(3) Jonga ukukhululeka kweplagi ye-oyile ye-oyile kunye nokuba kukho ukuqhekeka kumkhono weplunger. Qwalasela umphezulu we-injector plunger sleeve umonakalo kunye ne-flatness kwindawo yoqhagamshelwano eqhubekayo yomkhono we-plunger (indawo yebhanti elimnyama). Coca ngokucokisekileyo kwaye uvuthele yomise yonke ifilimu yeoli kumkhono weplunger phambi kokuba ube bluing. Jonga ukuba mcaba komphezulu osicaba ngepleyiti ethe tyaba (ekukhethwa ukuba ipleyiti yokusila) kunye ne "bluing agent". Ukuba umonakalo okanye ukungalingani kufunyenwe, kufuneka kube phantsi kwaye kulungiswe. Musa ukusebenzisa ilaphu le-emery okanye ibrashi yocingo kumphezulu woqhagamshelwano phakathi komkhono weplunger kunye nentloko yomlomo.

(4) Ukuba i-injector ishushu ngokugqithiseleyo, i-gasket yokutywina phakathi komkhono we-plunger kunye nomzimba wesitofu unokunyibilika. Intloko yomlomo eqinile iya kukhululeka. Ngenxa yoko, ioli yokuthambisa isenokuhlanjululwa, imingxuma yesitofu ivaleke, kwaye konakaliswe imikhono yesitofu okanye iiplunger.

(5) Isiziba se-oyile kunye nemingxuma yokubuyisela kumkhono omkhulu weplunger imalunga ne-1.27 ~ 1.65 mm ukuphakama kunemingxuma yeoli kumkhono oqhelekileyo weplunger. Ii-injection ze-fuel eziqhelekileyo kunye ne-injection enkulu yamafutha ayinakuxutywa kwi-injini ye-diesel enye.
