Iyini ipompo likaphethiloli lemoto
Iphampu kaphethiloli yemoto iyingxenye ebalulekile yesistimu yokuphakelwa kukaphethiloli yemoto. Umsebenzi wayo oyinhloko ukumunca uphethiloli ethangini bese uwucindezela uye ekamelweni lokuntanta le-carburetor lenjini ngepayipi kanye nesihlungi sikaphethiloli. Umgomo wokusebenza wephampu kaphethiloli uhlanganisa izinhlobo ezimbili zohlobo lwe-diaphragm yokushayela ngomshini kanye nohlobo lwe-electric drive:
Iphampu kaphethiloli yohlobo lwe-diaphragm eqhutshwa ngomshini : Lolu hlobo lwephampu kaphethiloli luqhutshwa yisondo elingavamile ku-camshaft. Lapho i-camshaft ijikeleza, ingalo eshisayo ephezulu engavamile idonsa induku yokudonsa yefilimu yephampu, bese ifilimu yephampu iwela ukuze ikhiqize ukumunca, imunce uphethiloli ethangini, bese ingena egumbini likaphethiloli ngepayipi likaphethiloli kanye nesihlungi sikaphethiloli. Lapho i-eccentric ingasakwazi ukushukumisa ingalo, isiphethu se-membrane yephampu siyakhula futhi sisunduze i-membrane yephampu ukuze sicindezele uphethiloli kusuka ku-valve yokuphuma uye ekamelweni lokuntanta le-carburetor. Inzuzo yale ndlela ukuthi isakhiwo silula, kodwa sithinteka kakhulu ukushisa kwenjini .
Iphampu kaphethiloli eqhutshwa ngogesi: Lolu hlobo lwephampu kaphethiloli aluncikile ku-camshaft, kodwa luncikile emandleni kagesi ukuze ludonse ifilimu yephampu ngokuphindaphindiwe. Iphampu kaphethiloli ingakhetha ngokukhululekile indawo yokufaka, futhi ingavimbela ukumelana nomoya. Kunezindlela ezimbili ezivamile zokufaka amaphampu kaphethiloli kagesi: eyodwa ifakiwe emgqeni wokuphakelwa kaphethiloli, kanti enye ifakiwe ethangini likaphethiloli. Iphampu kaphethiloli efakwe ephayiphini lokuphakelwa kaphethiloli kulula ukuyifaka nokuyiqaqa, kodwa ingxenye yokumunca kaphethiloli inde futhi kulula ukuyiphakelwa emoyeni, futhi umsindo osebenzayo mkhulu; Iphampu kaphethiloli yephampu kaphethiloli efakwe ethangini likaphethiloli ilula, umsindo ophansi, iyona eyinhloko yamanje.
Umgomo wokusebenza wephampu kaphethiloli: lapho iphampu kaphethiloli isebenza, ukugeleza kudingeka kuhlangatshezwane nokusetshenziswa kokusebenza kwenjini kanye nesidingo sokugeleza kokubuya kukaphethiloli ukuqinisekisa ukucindezela okuzinzile kohlelo lukaphethiloli kanye nokupholisa okwanele. Ukunikezwa kukaphethiloli okuphezulu kwephampu kaphethiloli evamile kukhulu ngokuphindwe kabili kuya kathathu kunokusetshenziswa kukaphethiloli okuphezulu kwenjini. Lapho uwoyela wephampu ungaphezu kokusetshenziswa kukaphethiloli, ivalvu yenaliti yegumbi lokuntanta le-carburetor ivaliwe, futhi ukucindezela komugqa wokukhipha iphampu kaphethiloli kuyanda, okungafinyeza ukuhamba kwe-diaphragm noma kuyeke ukusebenza.
Ukugcinwa kanye nokufakwa esikhundleni kwephampu kaphethiloli: Ngemva kweminyaka emibili noma emithathu yokusebenzisa imoto, ngenxa yokungcola kukawoyela kanye nokuguguleka nezinye izizathu, amandla ephampu kaphethiloli angancipha, futhi kudingeka ihlanzwe noma ishintshwe. Ukukhetha iphampu kaphethiloli efanele kunomthelela obalulekile emphumeleni wokusebenza kwenjini kanye nokusetshenziswa kukaphethiloli.
Indima eyinhloko yephampu kaphethiloli yemoto ukumunca uphethiloli ethangini bese uwudlulisela enjinini ngemva kokucindezela ukuqinisekisa ukuthi uhlelo lukaphethiloli lungahlinzeka ngophethiloli ozinzile. Ngokukhethekile, iphampu kaphethiloli, eqhutshwa yimoto kagesi, idonsa futhi icindezele uphethiloli ethangini, bese iwuthumela ngemigqa kanye nesihlungi sikaphethiloli ekamelweni lokuntanta le-carburetor, noma ngqo ku-intake manifold noma isilinda senjini ukuze imoto iqhubekele phambili.
Indlela amaphampu kaphethiloli asebenza ngayo
Iphampu kaphethiloli ivame ukuqhutshwa yinjini, esebenzisa ukujikeleza kwesivinini esikhulu senjini ukushayela i-impeller ukuze ijikeleze, ngaleyo ndlela kudala indawo enomfutho ophansi emzimbeni wephampu, bese uphethiloli osethangini udonswa emzimbeni wephampu bese uthuthwa uye enjinini ngomugqa wokuphuma. Ukuze ibhekane nobunzima bokumuncwa kwamafutha lapho izinga lamafutha liphansi, imoto yephampu kaphethiloli inomthamo othile wokulayisha ngokweqile, ongakhulisa amandla ngokuzenzakalelayo lapho uphethiloli uncishisiwe ukuqinisekisa ukunikezwa okuqhubekayo kukaphethiloli.
Izinhlobo kanye nezici zokuklama zamaphampu kaphethiloli
Amaphampu kaphethiloli angahlukaniswa ngezinhlobo ezimbili ngokwezindlela ezahlukene zokushayela: uhlobo lwe-diaphragm yokushayela ngomshini kanye nohlobo lwe-electric drive. Izimoto zanamuhla zisebenzisa kakhulu amaphampu kaphethiloli kagesi, anezinzuzo zenani elikhulu lamafutha ephampu, umfutho ophezulu wephampu, ukuzinza okuhle, umsindo ophansi, impilo ende njalo njalo. Ngaphezu kwalokho, iphampu kaphethiloli nayo inemisebenzi ehlukahlukene yokulawula, njengomsebenzi wangaphambi kokusebenza, umsebenzi wokusebenza ngesivinini esingaguquki, njll., ukuqinisekisa ukuthi injini ingathola ukunikezwa kukaphethiloli okuzinzile ngaphansi kwezimo zokusebenza ezahlukene.
