Ahlelwa kanjani ama-injection epompo ezinjinini zikadizili?

Njengoba igama liphakamisa, ama-injector epompo ayinhlanganisela yepompo kanye nomjovo. Yiqiniso, lokhu kulula kakhulu futhi akutsheli konke ngalesi sinqumo, kodwa kuseduze kakhulu neqiniso. Umjovo ngamunye unomhlangano wawo wamafutha omfutho ophezulu. Lesi sixazululo sinezinzuzo zaso, kodwa futhi kukhona nezinkinga ezinkulu. Asebenza kanjani ama-injection epompo nokuthi angawavuselela kanjani? Bheka izimpendulo embhalweni wethu!

Pump nozzles - design izixazululo design

Le divayisi iyingxenye yamandla eyinhloko ezinjinini zikadizili. Iqukethe umlomo wombhobho ohlanganiswe nesilinda. Lona wakamuva unesibopho sokwandisa umfutho kaphethiloli okhona kuwo. Ama-injection ephampu ama-injection ama-injection anesigaba sepompo esengeziwe esisebenza ngesimiso esifanayo njengasempompini yokucindezela okuphezulu. I-nozzle ngayinye inesigaba sayo. Ngaphezu kwalokho, ithimba lihlome ngalezi zinto ezilandelayo:

• imigqa yokucindezela okuphezulu nokuphansi;
• i-valve yokuvala i-dosing;
• i-spire;
• iziphethu;
• ukufutheka;
• i-valve yokusiza.

Pump nozzles - isimiso sokusebenza

Ezinjinini zendabuko ezinamaphampu kaphethiloli anomfutho ophezulu, ukunyakaza okujikelezayo kwesondo legiya kudluliselwa kumongo wemishini yomjovo. Lokhu kuvezwa emsebenzini wezakhi ngazinye. Ngakho-ke, ukucindezelwa kukaphethiloli kwakhiwa, okuthi ngendlela ecindezelwe kungena emibhobho. Ama-injection amayunithi asebenza ngendlela ehlukile ngoba ukunyakaza okunikeza amandla okuwasebenzisa kuvela ku-camshaft lobes. Nasi isimiso sokusebenza: 

• ukugxuma okusheshayo kwamakhamera kubangela ukuthi i-piston ihambe esigabeni sikaphethiloli futhi idale ukucindezela okufunayo;
• amandla e-spring tension adluliwe futhi inaliti ye-nozzle iphakanyisiwe;
• umjovo kaphethiloli uyaqala.

Amaphampu omjovo - isimiso sokusebenza kanye nezinzuzo

Ubuhle obungangabazeki bokusebenzisa amayunithi ama-injection yingcindezi ephezulu kakhulu ye-atomized diesel fuel. Kwezinye izimo, ifinyelela ibha engu-2400, engaqhudelana nohlelo lwamanje lwe-Common Rail. Ama-injection epompo anciphisa nokuba khona kwezinye izingxenye zenjini ezihambayo, okunciphisa izindleko zokuyigcina (okungenani ngombono).

Isebenza kanjani injini yepompo yomjovo? Isixazululo Ububi

Lapha siphendukela kokungalungi kwalesi sixazululo, ngoba idizili isebenza kanzima futhi inomsindo. Ukucindezela esigabeni sepompo kuphakama kancane futhi ngokushesha, okubangela umsindo. Ukwengeza, amayunithi okujova awakwazi ukwenza izigaba ezingaphezu kwezimbili zomjovo. Lokhu kwenza kube nzima ukuthulisa ukusebenza kwedivayisi yokushayela. Amayunithi anjalo awahlangabezani nezindinganiso zokukhipha umoya oqinile, ngakho-ke izinjini ezintsha zikadizili zifakwe amasistimu kaloliwe ajwayelekile.

Ingabe ama-injection ephampu ahlala isikhathi eside emotweni?

Kumele kuvunywe ukuthi umklamo ubhekwa ochwepheshe njengosebenza kakhulu futhi uhlala isikhathi eside. Uma umshayeli enakekela i-refueling ngophethiloli wekhwalithi ephezulu kanye nokushintshwa okujwayelekile kwesihlungi sikaphethiloli, i-mileage yamakhilomitha ayizinkulungwane ezingama-250-300 ngaphandle kokuvuselelwa ingokoqobo. Kukhona enye inkinga ebalulekile, i.e. shintsha amafutha kulawo anconywe umenzi. Ama-injection epompo aqhutshwa yi-camshaft enamakhamera amaningi kunamanye amamodeli. Ukugcwalisa uhlobo oluhlukile lwamafutha kungaholela ekuhlulekeni kwezakhi ezibhekene nokudlulisa amandla ku-piston yesigaba sikaphethiloli.

Ama-injection ephampu kanye nomklamo wekhanda lenjini

Lapha kuvela obunye ubunzima. Eyunithi yamandla, izintambo zikagesi ezinde kanye nayo yonke iphampu kaphethiloli enengcindezi ephezulu nokushayela kwayo kunqanyuliwe. Ukwakheka okuyinkimbinkimbi kwekhanda lenjini akusizi, okuphoqa umshayeli ukuthi alawule kahle imoto. Kubaluleke kakhulu ukunakekela izikhathi ezivamile zokushintsha amafutha. Esinye sezilonda sikhipha izidleke lapho kuthengiswa khona iphampu yomjovo. Khona-ke kuzodingeka uqale ama-socket bushings noma ushintshe ikhanda lonke.

Umjovo wephampu - ukuvuselelwa kwezinto zokunikezwa kukaphethiloli ezilimele

Uhamba kanjani umsebenzi? Ekuqaleni, uchwepheshe uhlola idivayisi futhi uyayiqaqa. Ukuhlanza okunembile kanye nemishini yokuxilonga kumvumela ukuthi anqume izinga lokugqoka kwezingxenye. Ngokusekelwe kulokhu nangemva kokucacisa izindleko nekhasimende (ngokuvamile kufanele kube), kuyadingeka ukucacisa ububanzi bokulungisa. Ezimweni ezibucayi, lapho ukuvuselelwa kungenakwenzeka, kuyadingeka ukushintsha ama-injection amayunithi amasha noma avuselelwe.

Iphampu yomjovo noma iphampu yomjovo - iyiphi injini ongayikhetha

Injini esebenza kahle efakwe izijovo zamayunithi ayisebenzi kahle. Nokho, imakethe ibuswa yiCommon Rail solutions, kanti ubuchwepheshe esibuchazayo buzophela kancane kancane. Uma unethezekile ngokusebenza kwenjini esindayo, ungakhetha inketho ngamayunithi ama-injection. Ngokuqinisekile banezakhi ezimbalwa ezingalimala. Emayunithi anamaphampu kaphethiloli anengcindezi ephezulu, akhona impela amaningi, kepha athethelela ukunganaki okuncane, isibonelo, endabeni yokuthulula amafutha.

Ukulungiswa kwe-chip yenjini ne-pump injector - kuyafaneleka?

Njenganoma yimuphi udizili wesimanje, ukwanda okukhulu kwamandla kungafinyelelwa ngokushintsha imephu yenjini. Ukushunwa kwe-chip okwenziwa ngobungcweti akuthinti ukusebenza kwamayunithi okujova. Ngeke kube ne-contraindications eyakhayo ekusetshenzisweni kwayo. Umbuzo wesibili, yiqiniso, izinga lezingxenye ngokwazo ngesikhathi sezinguquko. Ngokuvamile, njengoba amandla enyuka, izinga lokusebenza kwenjini liyanda, okungaba nomthelela omubi empilweni yayo yesevisi.

Umjovo wepompo uyisixazululo sezobuchwepheshe, okuthi, nokho, esingahlangabezani nezindinganiso zokukhishwa kwephampu futhi sizofiphala ngemuva. Ingabe kuwufanele ukuthenga imoto efakwe ngayo? Lokhu kuthonywa kakhulu isimo senjini kanye nama-unit injection uqobo. Kala zonke izinzuzo nezingozi esizibalile futhi wenze isinqumo esihlakaniphile.
