iphampu kaphethiloli
Umsebenzi wephampu kaphethiloli ukumunca uphethiloli ethangini likaphethiloli bese uwucindezela ungene ekamelweni elintantayo le-carburetor ngepayipi kanye nesihlungi sikaphethiloli. Kungenxa yephampu kaphethiloli ukuthi ithangi likaphethiloli lingabekwa ngemuva kwemoto kude nenjini nangaphansi kwenjini.
Amaphampu kaphethiloli angahlukaniswa ngohlobo lwe-diaphragm oluqhutshwa ngomshini kanye nohlobo oluqhutshwa ngogesi ngokwezindlela ezahlukene zokushayela.
Isingeniso
Umsebenzi wephampu kaphethiloli ukumunca uphethiloli ethangini likaphethiloli bese uwucindezela ungene ekamelweni elintantayo le-carburetor ngepayipi kanye nesihlungi sikaphethiloli. Kungenxa yephampu kaphethiloli ukuthi ithangi likaphethiloli lingabekwa ngemuva kwemoto kude nenjini nangaphansi kwenjini.
Ukuhlukaniswa
Amaphampu kaphethiloli angahlukaniswa ngohlobo lwe-diaphragm oluqhutshwa ngomshini kanye nohlobo oluqhutshwa ngogesi ngokwezindlela ezahlukene zokushayela.
Iphampu kaphethiloli ye-diaphragm
Iphampu kaphethiloli ye-diaphragm imele iphampu kaphethiloli yomshini. Isetshenziswa enjinini ye-carburetor futhi ngokuvamile iqhutshwa yisondo elingavamile ku-camshaft. Izimo zayo zokusebenza yilezi:
① Ngesikhathi sokujikeleza kwe-camshaft yokumunca uwoyela, lapho isondo eliyindilinga lisunduza ingalo ye-rocker futhi lidonsa phansi induku yokudonsa ye-diaphragm yephampu, i-diaphragm yephampu iyehla ukuze ikhiqize ukumunca, bese uphethiloli ukhishwa ethangini likaphethiloli bese ungena ephampini likaphethiloli ngepayipi likaphethiloli, igumbi lokuhlunga uphethiloli.
②Uwoyela wokupompa Lapho isondo eliyindilinga lijikeleza nge-engeli ethile futhi lingasaphushi ingalo ye-rocker, intwasahlobo ye-membrane ye-pump iyanwebeka, isunduze i-membrane ye-pump phezulu, bese uphethiloli ocindezelayo usuka ku-valve yokuphuma kawoyela uye ekamelweni elintantayo le-carburetor.
Amaphampu kaphethiloli e-diaphragm abonakala ngesakhiwo esilula, kodwa ngenxa yokuthi athintwa ukushisa kwenjini, kufanele kuqashelwe ngokukhethekile ukuqinisekisa ukusebenza kahle kokupompa emazingeni okushisa aphezulu kanye nokuqina kwe-diaphragm yerabha ngokumelene nokushisa namafutha.
Ngokuvamile, ukunikezwa kukaphethiloli okuphezulu kwephampu kaphethiloli kukhulu ngokuphindwe kabili kuya kathathu kunesilinganiso esiphezulu sokusetshenziswa kukaphethiloli kwenjini kaphethiloli. Uma umthamo kaphethiloli wephampu ukhulu kunesilinganiso esiphezulu sokusetshenziswa kukaphethiloli futhi ivalvu yenalidi ekamelweni lokuntanta le-carburetor ivaliwe, ingcindezi epayipini lokuphuma kukaphethiloli lephampu kaphethiloli iyanda, okuthi kuphendule ephampu kaphethiloli, kufinyeze ukushaywa kwe-diaphragm noma kumise umsebenzi.
iphampu kaphethiloli kagesi
Iphampu kagesi kaphethiloli ayinciki ku-camshaft ukuze ishayele, kodwa inciki kumandla kagesi ukuze imunce ulwelwesi lwephampu ngokuphindaphindiwe. Lolu hlobo lwephampu kagesi lungakhetha ngokukhululekile indawo yokufaka, futhi lungavimbela ukwenzeka kokukhiya komoya.
Izinhlobo eziyinhloko zokufakwa kwamaphampu kaphethiloli kagesi ezinjini zokujova uphethiloli zifakwa epayipini lokuphakelwa kukaphethiloli noma ethangini likaphethiloli. Eyokuqala inobubanzi obukhulu bokuhlela, ayidingi ithangi likaphethiloli eliklanywe ngokukhethekile, futhi kulula ukuyifaka nokuyiqaqa. Kodwa-ke, ingxenye yokumunca uwoyela yephampu kaphethiloli inde, kulula ukukhiqiza ukumelana nomoya, futhi umsindo osebenzayo nawo mkhulu kakhulu. Ngaphezu kwalokho, kuyadingeka ukuthi iphampu kaphethiloli ingavuzi. Lolu hlobo aluvamile ukusetshenziswa ezimotweni ezintsha zamanje. Eyokugcina inamaphampu kaphethiloli alula, umsindo ophansi, kanye nezidingo eziphansi zokuvuza kaphethiloli okuningi, okuyisitayela esiyinhloko samanje.
Uma usebenza, izinga lokugeleza kwephampu kaphethiloli akufanele nje linikeze ukusetshenziswa okudingekayo ekusebenzeni kwenjini, kodwa futhi liqinisekise ukugeleza okwanele kokubuya kukawoyela ukuqinisekisa ukuqina kwengcindezi kanye nokupholisa okwanele kohlelo lukaphethiloli.
