Iyini ipompo yemoto kaphethiloli
Iphampu yemoto kaphethiloli iyingxenye ebalulekile yohlelo lokuhlinzekelwa kwamafutha ezimotweni. Umsebenzi wayo oyinhloko ukuncela uphethiloli ngaphandle kwethangi bese ucindezela kuyo egumbini le-carburetor float yasenjini ngepayipi kanye nesihlungi sikaphethiloli. Umgomo osebenzayo wepompo kaphethiloli ufaka izinhlobo ezimbili zohlobo lwe-mechanical drive diaphragm nohlobo lwedrayivu kagesi:
I-Mechacted Diaphragm yohlobo lwePhetro Pheroli Phepha: Lolu hlobo lwepompo kaphethiloli luqhutshwa isondo le-eccentric kwi-camshaft. Lapho i-camshaft ijikeleza, ingalo ephezulu yokuthuthumela phezulu idonsa induku yokudonsa ifilimu lepompo, futhi ifilimu lepompo liwela ukukhiqiza ukumunca, ukuncela uphethiloli kusuka ethangini, bese ungena ethangini lamafutha ngepayipi kaphethiloli. Lapho i-eccentric ingaseyona ikonakalisa ingalo, intwasahlobo yepompo yenyuka inwebeka futhi iphoqe ulwelwesi lwepompo ukucindezela uphethiloli kusuka ku-outlet valve kugumbi le-carburetor float. Inzuzo yale ndlela ukuthi ukwakheka kulula, kepha kuthinteka kakhulu ekushiseni kwenjini.
Ipompo kaphethiloli kagesi kagesi: Lolu hlobo lwepompo kaphethiloli aluthembeli kwi-camshaft, kepha luthembele kumandla we-electromagnetic aphinda adonse ifilimu lepompo. Iphampu kagesi ingakhetha ngokukhululekile isikhundla sokufaka, futhi ingavimba ukumelana komoya. Kunezindlela ezimbili ezijwayelekile zokufaka amaphampu kaphethiloli kagesi: Kufakwe emugqeni wokuhlinzekwa kawoyela, kanti enye ifakwe ethangini likaphethiloli. Iphampu kagesi efakwe epayipi lokuhlinzekwa ngowoyela kulula ukuyifaka futhi ihlukanise, kepha isigaba se-oyili sokumisa isikhathi eside futhi kulula ukumelana nomoya, futhi umsindo osebenzayo mkhulu; Ipayipi likaphethiloli likagesi kagesi elifakwe ethangini likaphethiloli lilula, linomsindo ophansi, liyinto ejwayelekile yamanje.
Umgomo osebenzayo wepompo kaphethiloli: Lapho ipompo kaphethiloli isebenza, ukugeleza kudinga ukufeza ukusetshenziswa kokusebenza kwenjini kanye nokufunwa kokugeleza kwamafutha okubuyisa ukugeleza kohlelo lwamafutha nokupholisa okwanele. Ukuhlinzekwa kawoyela okuphezulu kwephampu kaphethiloli elijwayelekile kungama-2,5 kuya ku-3.5 izikhathi ezinkulu kunokusetshenziswa okuphezulu kwenjini. Lapho uwoyela wepompo mkhulu kunokwenziwa ngophethiloli, i-valve ye-valve ye-carburetor float igumbi livaliwe, futhi ingcindezi yomugqa wepompo wamaphampu enyuka, onganciphisa i-diaphragm ukuhamba noma ukuyeka ukusebenza.
Ukulungiswa kanye nokubuyiselwa kwempompo kaphethiloli: Ngemuva kweminyaka emibili noma emithathu yokusebenzisa imoto, ngenxa yokungcola kawoyela nokugqoka nezinye izizathu, amandla wepompo kaphethiloli angancishiswa, futhi adinga ukuhlanzwa noma ukushintshwa. Ukukhetha iphampu ye-petroline efanele kunomthelela obalulekile emsebenzini wokusebenza wenjini nokusetshenziswa kwamafutha.
Iqhaza eliphambili lepompo ye-automobile kaphethiloli ukuncela uphethiloli ngaphandle kwethangi bese uyidlulisela enjini ngemuva kokucindezela ukuqinisekisa ukuthi uhlelo lwamafutha lunganikeza amafutha aqinile. Ngokukhethekile, ipompo kaphethiloli, eqhutshwa yimoto kagesi, idonsa futhi inqameze uphethiloli ethangini, bese iyithumela ngemigqa nokuhlunga kophethiloli ku-ntambama yokudla ye-carburetor, noma ngokuqondile ku-injini ukuze iqhume imoto phambili.
Isebenza kanjani amaphampu kaphethiloli
Iphampu kaphethiloli ivame ukuqhutshwa yimoto, esebenzisa ukujikeleza okusheshayo kwemoto ukushayela umlohlisi ukujikeleza, ngaleyo ndlela kwamukelwe indawo ethangiwe emzimbeni wepompo, futhi uphethiloli ethangini lingena emzimbeni wepompo bese lihanjiswa enjini entanjeni. Ukuze ubhekane nobunzima bokuvalwa kwamafutha lapho izinga lamafutha liphansi, i-oyili motor motor inamandla athile agcwele ngokweqile, angakhulisa amandla ngokuzenzakalela lapho kuncishiswa uphethiloli ukuze aqinisekise ukunikezwa uphethiloli oqhubekayo.
Izinhlobo nezinhlobo zezimpawu zamaphampu kaphethiloli
Amaphampu kaphethiloli angahlukaniswa ngezinhlobo ezimbili ngokuya ngezindlela ezahlukahlukene zokushayela: uhlobo lwe-mechanical drive diaphragm nohlobo lwedrayivu kagesi. Izimoto zanamuhla zisebenzisa kakhulu amaphampu kagesi kagesi, anezinzuzo zenani elikhulu lamafutha epompo, umfutho wempompo ephezulu, ukuqina okuhle, impilo ephansi, impilo ephansi nokunye. Ngaphezu kwalokho, ipompo kaphethiloli ibuye ibe nemisebenzi ehlukahlukene yokulawula, njengokusebenza kwangaphambi kokusebenza, umsebenzi wokusebenza wejubane, njll., Ukuqinisekisa ukuthi injini ingathola ukutholakala kwamafutha aqinile ngaphansi kwezimo eziqinile zokusebenza.
