Iphampu likaphethiloli.
Umsebenzi wepompo likaphethiloli ukumunca uphethiloli ethangini bese uwucindezela ngepayipi kanye nesihlungi sikaphethiloli egumbini lokuntanta le-carburetor. Kungenxa yephampu kaphethiloli okwenza ithangi likaphethiloli libekwe ngemuva kwemoto, kude nenjini, nangaphansi kwenjini.
Iphampu kaphethiloli ngokuya ngemodi yokushayela ehlukile, ingahlukaniswa ngohlobo lwe-diaphragm yemishini kanye nohlobo lwe-electric drive.
Iphampu kaphethiloli ngokuya ngemodi yokushayela ehlukile, ingahlukaniswa ngohlobo lwe-diaphragm yemishini kanye nohlobo lwe-electric drive.
Iphampu kaphethiloli yohlobo lwe-diaphragm
Iphampu kaphethiloli yohlobo lwe-Diaphragm imele iphampu kaphethiloli engumshini, esetshenziswa enjinini ye-carburetor, evame ukushayelwa isondo le-eccentric ku-camshaft, isimo sayo sokusebenza sithi:
① Ukushintshwa kwe-camshaft yokumunca uwoyela, lapho i-eccentric top inyakazisa ingalo, idonsela phansi i-pump film rod, futha ifilimu phansi, ikhiqize ukumunca, uphethiloli uzomuncwa ethangini, futhi ngepayipi likawoyela, isihlungi sikaphethiloli, ungene egumbini likawoyela iphampu kaphethiloli.
② Uwoyela wepompo Uma i-eccentric iphenduka i-Angle ethile futhi ingasaphakamisi ingalo yokunyakazisa, isiphethu sefilimu yepompo siyelulelwa, ifilimu yepompo iyakhuphuka, futhi uphethiloli ucindezelwa ukusuka ku-valve yokukhipha uwoyela kuya egumbini lokuntanta le-carburetor.
Iphampu kaphethiloli yohlobo lwe-diaphragm ibonakala ngesakhiwo sayo esilula, kodwa ngenxa yemiphumela eshisayo yenjini, ukunakwa okukhethekile kufanele kukhokhwe ukuze kuqinisekiswe ukusebenza kukawoyela wephampu emazingeni okushisa aphezulu, kanye nokuqina kwe-diaphragm yezinto zenjoloba ekushiseni nasekushiseni. amafutha.
Ukunikezwa kukawoyela okuphezulu kwephampu kaphethiloli jikelele kuyizikhathi ezi-2.5 kuye kwezingu-3.5 ezinkulu kunokusetshenziswa okuphezulu kukaphethiloli wenjini kaphethiloli. Lapho uwoyela wepompo mkhulu kunokusetshenziswa kukaphethiloli futhi i-valve yenaliti yegumbi lokuntanta le-carburetor ivaliwe, ingcindezi emgqeni wokuphuma kwepompo kawoyela iyanda, isabela kupompo likawoyela, futhi ukuhamba kwe-diaphragm kufinyezwa noma kuyeka ukusebenza.
Iphampu likaphethiloli kagesi
Iphampu kaphethiloli kagesi, engashayelwa i-camshaft, kodwa ngamandla kazibuthe kagesi okuphindaphinda ifilimu yepompo yokumunca. Iphampu kagesi ingakhetha ngokukhululekile indawo yokufaka, futhi ingavimbela into yokumelana komoya.
Izinhlobo eziyinhloko zokufakwa kwamaphampu kaphethiloli kagesi wezinjini zomjovo kaphethiloli zifakwa kulayini wokuphakela uwoyela noma ethangini likaphethiloli. Eyokuqala inesakhiwo esikhulu, ayidingi umklamo okhethekile wethangi likaphethiloli, futhi kulula ukuyifaka nokuhlakaza. Kodwa-ke, isigaba sokudonsa ipompo likawoyela side, kulula ukukhiqiza ukumelana komoya, futhi umsindo osebenzayo mkhulu, ngaphezu kwalokho, ipompo likawoyela akufanele livuze, futhi lolu hlobo lusetshenziswe kancane ezimotweni ezintsha zamanje. Ipayipi lakamuva likaphethiloli lilula, umsindo ophansi, izidingo zokuvuza kwamafutha amaningi aziphezulu, iwona mkhuba wamanje oyinhloko.
Emsebenzini, ngaphezu kokuhlinzeka ukusetshenziswa okudingekayo ekusebenzeni kwenjini, ukugeleza kwepompo likaphethiloli kufanele futhi kuqinisekise ukuthi kukhona ukugeleza okwanele kokubuyisela ukuze kuqinisekiswe ukuzinza kwengcindezi yesistimu kaphethiloli kanye nokupholisa okwanele.
Yiziphi izimpawu zokuhluleka kwepompo likaphethiloli
Izimpawu zokuhluleka kwephampu kaphethiloli zihlanganisa, kodwa azikhawulelwe ku:
Imoto inzima ukuyiqalisa futhi ingase idinge ukuthungela okuningi ukuze iqale.
I-acceleration ibuthakathaka, futhi imoto ayikwazi ukufuthelwa uma ishayela, noma ivaliwe.
Injini iyanyakaza futhi ukukhanya okungalungile kuyakhanya.
Kunomuzwa wokukhungatheka lapho usheshisa ngokushesha.
Injini inomsindo ongavamile lapho ushayela, njengomsindo ovungamayo.
Ukusetshenziswa kukaphethiloli okungavamile, ukwanda okungenzeka.
Izimpawu zokucindezela okuphansi empompini endala kaphethiloli yase-Bora zingase zihlanganise isidingo sokubasa okuningi ukuze uqalise imoto, ukusheshisa okubuthakathaka ngenkathi ushayela, kanye namajita enjini angenzeka kanye nezibani zezinkinga. Lezi zimpawu zibonisa ukuthi iphampu kaphethiloli ingase ingakwazi ukunikeza ukucindezela okwanele kwamafutha, okuthinta ukusebenza okuvamile kwenjini.
