Izimo Zokuvuza Kawoyela kanye Nezindlela Zokwelashwa Zokuqhunyiswa Okubalulekile

Ukuvuza kwamafutha kuma-laminations ayisisekelo kubonakala ngezindlela ezihlukahlukene, ngakho-ke izindlela zokwelashwa kufanele zinqunywe ngokusekelwe ezimweni ezithile. I-fuel injector iyingxenye yokunemba. Uma injini isebenzisa udizili ongahlanzekile noma isinesevisi isikhathi eside, ukubuyiswa kukawoyela kungase kwenzeke ngenxa yokuguga komjovo kaphethiloli.

Kodwa-ke, njengoba ukufaka esikhundleni somjovo kaphethiloli kubiza futhi kungenamali, uwoyela obuyisiwe ungaqondiswa kabusha ethangini likaphethiloli ngepayipi elibuyisela emuva noma uhanjiswe kusihlungi sikadizili ukuze kuvinjelwe ukumoshakala. Uma ipayipi elibuyayo lonakele, ingxenye yepayipi lepulasitiki ingasetshenziswa ukuqondisa amafutha esitsheni esihlukile, lapho angase ahlungwe khona ngaphambi kokuba aphinde athululelwe ethangini.

Okwesibili, ukuvuza kukawoyela ohlelweni lokulethwa kukaphethiloli kungaphathwa ngendlela efanele ngokusekelwe esimweni esithile: Uma iwasha kusikulufu esingenalutho sepayipi likaphethiloli singalingani, singasuswa, sishaye phansi, futhi sifakwe kabusha. Uma lokhu kungayixazululi inkinga, iwasha ingashintshwa kufakwe entsha, noma ugqinsi oluthambile lwepulasitiki lungasikwa lube yi-gasket esikhundleni.

Ukuvuza kwamafutha esihlanganisi phakathi kwepayipi likaphethiloli lepulasitiki nesixhumi sensimbi ngokuvamile kubangelwa ukuqina noma ukuqhekeka kwepayipi lepulasitiki. Ingxenye eqinile noma eqhekekile inganqunywa, futhi ipayipi esele ingathambisa ngamanzi ashisayo. Ngenkathi kushisa, ingafakwa kusixhumi sensimbi futhi iboshwe ngokuvikelekile ngentambo yensimbi. Ukuze uthole ipayipi yensimbi ephukile, indawo ephukile ingalungiswa ngokusebenzisa i-copper brazing. Ukwengeza, ukuvimbela ipayipi likaphethiloli ekuqhekekeni ngesikhathi sokufakwa, i-angle yokugoba kufanele ifanele; akufanele iphoqwe endaweni, futhi umzimba wepayipi akufanele uhlangane nebhulokhi yenjini ukugwema ukuguga.

Lapho ufaka isembozo se-valve, amandla okuqinisa ngokweqile angabangela kalula ukuthi siwohloke futhi avuze uwoyela. Kulesi simo, ikhava ye-valve evuzayo kufanele isuswe, igaywe ngokucophelela futhi ihlelwe kabusha ngenduku yokhuni ukuze kubuyiselwe ukukhanya kwendawo yokuxhumana. Ngemva kwalokho, kungasetshenziswa i-gasket entsha ngaphambi kokuyifaka kabusha. Izingxenye ezihlukene ze-laminations eziyinhloko zidinga izindlela ezahlukene zokwelashwa zokuvuza kwamafutha, futhi ukunakekelwa kufanele kuthathwe phakathi nenqubo ukugwema ukubangela umonakalo emshinini.
