Iyini iphampu kaphethiloli futhi yiziphi izimpawu zepompo elibi likaphethiloli?
Ngaphambi kokufunda lesi sihloko,
khumbula ukuthi kunomehluko phakathi kwephampu yamafutha kanye nephampu yamafutha.
iphampu yomjovo. Kulesi sihloko, sixoxa ngepompo elilula likaphethiloli, futhi
eyaziwa ngokuthi i-lift noma iphampu yokudlulisa.
Umsebenzi oyinhloko wephampu yamafutha
uwukunikeza noma ukusunduza uphethiloli usuka ethangini likaphethiloli uye enjinini. Lawa mafutha akhiqizwa
Itholakalela i-carburetor, i-throttle body, i-port fuel injection noma idizili.
uhlelo lomjovo. Izinhlobo zamaphampu ezibalwe ngezansi zisetshenziswa kuye ngokuthi
izidingo zokucindezela, ukukhweza ukucupha/izindawo kanye nendlela yokusebenza
imijikelezo. Njengoba ubuchwepheshe buthuthuka, izinto zokwakha kanye nohlobo lwangempela lwepompo
nazo zithuthukisiwe.
Phakamisa iphampu - Njengomthetho, ipompo ye-booster "iphakamisa" uphethiloli.
kusuka ethangini bese uyimpompa enjinini ngengcindezi engu-3-8 psi. Iphampu ephakamisayo
iphampu engumshini, ngokuvamile eboshelwa eceleni kwebhulokhi yesilinda. Lolu hlobo
Iphampu iyiphampu ye-diaphragm esebenzisa i-lever esebenza ngekhamera
amacembe e-cam ahlinzeka ngokumunca okudingekayo ukuze kuqhutshekwe nokuhamba kukaphethiloli.
Dlulisa iphampu - Dlulisa iphampu ngencazelo
"ilahla" uphethiloli ukusuka ethangini ukuya lapho idingeka khona...ngokuvamile ngedizili
injini empompini yamafutha. Izinhlelo zokusebenza ezivame kakhulu zifakwe
ngaphandle enjinini noma empompini yamafutha e-high pressure ngokwayo futhi ishayelwa ngegiya
high pressure fuel futha. Njengoba uzobona esihlokweni sephampu yomjovo,
ezinye izinhlobo zamaphampu omjovo wedizili (ikakhulukazi ama-rotary) anezakhelwe ngaphakathi
dlulisa iphampu ngaphakathi kwepompo yomjovo ngokwayo.
iphampu kagesi - Iphampu yamafutha kagesi, kunjalo,
Uhlobo oluvame kakhulu lwepompo. Njengomthetho, lolu hlobo lwepompo lufakwe phakathi
ithangi likaphethiloli futhi "phusha" uphethiloli enjinini, noma ifakwe kuhlaka futhi
ekhipha uphethiloli ethangini...abe eseyiphusha ebheke enjinini. Lolu hlobo lwephampu
idala ingcindezi engu-30-80 psi futhi ifaneleka kangcono ezinjinini zanamuhla.
Izimpawu zephampu yamafutha ehlulekile:
1. Ukuqala okunzima…ngokweqile
ukugoba
2. Umsindo ethangini likaphethiloli noma ifremu
ujantshi (iphampu kagesi)
3. Injini iyaqala, kodwa bese iyama
4. Uwonga uphethiloli ompofu
5. Ukushintshashintsha kwesikali somfutho
