iphampu kaphethiloli
Umsebenzi wephampu kaphethiloli ukumunca uphethiloli ethangini likaphethiloli bese uwucindezela ungene egumbini lokuntanta le-carburetor ngepayipi kanye nesihlungi sikaphethiloli. Kungenxa yepompo likaphethiloli ukuthi ithangi likaphethiloli lingabekwa ngemuva kwemoto kude nenjini nangaphansi kwenjini.
Amaphampu kaphethiloli angahlukaniswa abe uhlobo lwe-diaphragm oluqhutshwa ngomshini kanye nohlobo olushayelwa ngogesi ngokwezindlela ezahlukene zokushayela.
Isingeniso
Umsebenzi wephampu kaphethiloli ukumunca uphethiloli ethangini likaphethiloli bese uwucindezela ungene egumbini lokuntanta le-carburetor ngepayipi kanye nesihlungi sikaphethiloli. Kungenxa yepompo likaphethiloli ukuthi ithangi likaphethiloli lingabekwa ngemuva kwemoto kude nenjini nangaphansi kwenjini.
Ukwahlukanisa
Amaphampu kaphethiloli angahlukaniswa abe uhlobo lwe-diaphragm oluqhutshwa ngomshini kanye nohlobo olushayelwa ngogesi ngokwezindlela ezahlukene zokushayela.
Iphampu ye-diaphragm kaphethiloli
Iphampu kaphethiloli ye-diaphragm imele iphampu yemishini kaphethiloli. Isetshenziswa enjinini ye-carburetor futhi imvamisa ishayelwa isondo le-eccentric ku-camshaft. Izimo zayo zokusebenza yilezi:
① Ngesikhathi sokuzungezisa kwe-camshaft yokumunca uwoyela, lapho isondo elingenasici liphusha ingalo ye-rocker futhi lidonsela phansi i-pump diaphragm pull rod, i-pump diaphragm yehla ukuze ikhiqize ukumunca, bese uphethiloli ukhishwa ethangini likaphethiloli bese ungena empompini kaphethiloli. ngepayipi likawoyela, igumbi lokuhlunga likaphethiloli.
②Uwoyela wokumpompa Lapho isondo elingenasici lizungeza nge-engeli ethile futhi lingasasunduzi ingalo ye-rocker, isiphethu solwelwesi lwepompo siyelula, siphushele ulwelwesi lwepompo lukhuphuke, futhi lucindezela uphethiloli osuka ku-valve yokukhipha uwoyela uye egumbini elintantayo le-carburetor.
Amaphampu kaphethiloli we-diaphragm abonakala ngesakhiwo esilula, kodwa ngenxa yokuthi athinteka ukushisa kwenjini, ukunakwa okukhethekile kufanele kukhokhwe ukuze kuqinisekiswe ukusebenza kokupompa emazingeni okushisa aphezulu kanye nokuqina kwe-diaphragm yerabha ngokumelene nokushisa namafutha.
Ngokuvamile, umthamo omkhulu kaphethiloli wephampu kaphethiloli uphindwe izikhathi ezingu-2.5 kuya kwezingu-3.5 kunomthamo omkhulu wokusetshenziswa kukaphethiloli wenjini kaphethiloli. Lapho umthamo kawoyela wepompo mkhulu kunokusetshenziswa kukaphethiloli kanye ne-valve yenaliti egumbini lokuntanta le-carburetor ivaliwe, ingcindezi epayipini lokuphuma likawoyela lepompo likawoyela liyakhuphuka, elisabela epompo likawoyela, lifinyeze ukushaywa i-diaphragm noma ukumisa umsebenzi.
iphampu kaphethiloli kagesi
Iphampu kaphethiloli kagesi ayincikile ku-camshaft ukuthi ishayele, kodwa incike emandleni kagesi ukumunca ngokuphindaphindiwe ulwelwesi lwepompo. Lolu hlobo lwephampu kagesi lungakhetha ngokukhululekile indawo yokufaka, futhi lungavimbela into yokukhiya umoya.
Izinhlobo eziyinhloko zokufakwa kwamaphampu kaphethiloli kagesi wezinjini zomjovo kaphethiloli zifakwa epayipini lokuhambisa uwoyela noma ethangini likaphethiloli. Eyangaphambili inobubanzi obukhulu besakhiwo, ayidingi ithangi likaphethiloli eliklanywe ngokukhethekile, futhi kulula ukulifaka nokuliqaqa. Kodwa-ke, ingxenye yokumunca uwoyela yephampu kawoyela yinde, kulula ukukhiqiza ukumelana komoya, nomsindo osebenzayo nawo mkhulu kakhulu. Ngaphezu kwalokho, kuyadingeka ukuthi ipompo likawoyela akumele livuze. Lolu hlobo aluvamile ukusetshenziswa ezimotweni ezintsha zamanje. Eyakamuva inamapayipi kaphethiloli alula, umsindo omncane, kanye nezidingo eziphansi zokuvuza kaphethiloli kaningi, okuwumkhuba wamanje oyinhloko.
Lapho usebenza, izinga lokugeleza kwepompo likaphethiloli akufanele linikeze kuphela ukusetshenziswa okudingekayo ekusebenzeni kwenjini, kodwa futhi kuqinisekiswe ukugeleza okwanele kokubuyisela uwoyela ukuze kuqinisekiswe ukuzinza kwengcindezi nokupholisa okwanele kwesistimu kaphethiloli.
