Pump: idivayisi iphinde izinguqulo

Isifutho sophethiloli umfutho ophakeme - ingenye izakhi eziyinhloko kohlelo umjovo we izinjini ezisebenza diesel. Le divayisi imisebenzi emibili - ngesikhathi yokucindezela isilinganiso esifanele diesel bese ilungisa edingekayo sokuqala Umjovo.

Inhloso futha iyunithi

Ngesisekelo lena ekhethekile futha plunger pair, ngokuhlanganisa piston (plunger) nge isilinda (emikhonweni). Le ndlela yokwenza yenziwa ngokuphelele insimbi engagqwali. Phakathi plunger kanye emkhonweni Kunegebe encane. Lokhu ukubhanqa ukunemba.

Kubalulekile ukuphawula ukuthi i-yamuva okwandile fuel futha elawula isikhathi umjovo ne injectors electronic.

Kuye Umklamo izinhlobo eziningana fuel amaphampu:

• Umugqa.
• Distribution.
• Wendlovu.

Ngokuvumelana kudivayisi umjovo futha kanje. Yena sifaka diesel ku uMbhalo esebenzisa ehlukile futha isici. Ngu design, kuba elula kakhulu. Ngokwesibonelo, amaphampu kagesi ube isakhiwo zabo plunger ambalwa. Bona ukumpompa futhi ukusabalalisa ukukhwezelwa zonke amasilinda.

Ngokuvamile, futha ukusatshalaliswa igcwaliswe nge pair of plungers. Ngenxa-ke ukulethela iyunifomu ngaphezulu nophethiloli. Ngokuphambene, e-line, lezi amaphampu kukhona ohlukaniswa ukukhanya kwabo nobukhulu ezincane. Ngakho-ke, imininingwane futha ukusatshalaliswa ngokuvamile abakwazi ukumelana imithwalo futhi behluleka. Lezi amaphampu ngokuvamile igcwele izimoto egijima ku-diesel.

Wendlovu umjovo futha

kudivayisi futha main sihluke kakhulu imiklamo odlule. futha umjovo okunjalo asetshenziswe uhlelo "Common Ryle," lapho enze umsebenzi ujova diesel phakathi wesitimela. Wendlovu amaphampu ukukhiqiza ingcindezi eliphakeme ohlelweni. Amanye amadivayisi ukunikeza umjovo ukucindezela 190 MPA. futha Kudivayisi "Mercedes Aktros" isibonelo, kufaka khona kuze 3 namabhuzu plungers. idrayivu yabo kwenziwa ngumuntu ekhethekile cam indandatho noma shaft.

Wawunodonga zonke izinhlobo futha yesimanje. I-apharathasi ngamunye wabo, njengoba sesibonile, kufaka khona okungenani oyedwa isici futha, lemali nezici zazo kuncike ukufana ukunikezela fuel uhlelo umjovo.

Uma futha ayisebenzi, supply fuel egumbini amandla omlilo liyaphela. Ngakho-ke kubalulekile ukuqapha isimo indlela. Futhi ekugcineni, siphawula ezinye zezimpawu esingasondela ngazo ukucacisa iphutha umjovo futha:

1. Idivayisi ine ezosetshenziswa umsindo wanda phakathi ukusebenza.
2. Nge futha igiya umba off ibhande.
3. Kusukela siyabhubha uphethiloli supply futha kuya injectors.
4. Kunzima sokuqala.
5. fuel Ukwandiswa ukusetshenziswa.
6. Kusukela ipayipi qeda nokubhamuka obukhulu black intuthu. Ngokuvamile, lokhu kubonisa isihlungi odla, kodwa ngemva esikhundleni, hlola futha yakho.
