Iphampu kaphethiloli.
Umsebenzi wephampu kaphethiloli ukumunca uphethiloli ethangini bese uwucindezela ngepayipi kanye nesihlungi sikaphethiloli uye ekamelweni lokuntanta le-carburetor. Kungenxa yephampu kaphethiloli ukuthi ithangi likaphethiloli lingabekwa ngemuva kwemoto, kude nenjini, nangaphansi kwenjini.
Iphampu kaphethiloli ngokwemodi yokushayela ehlukene, ingahlukaniswa ngohlobo lwe-diaphragm yedrayivu yemishini kanye nohlobo lwedrayivu kagesi lwesibili.
Iphampu kaphethiloli ngokwemodi yokushayela ehlukene, ingahlukaniswa ngohlobo lwe-diaphragm yedrayivu yemishini kanye nohlobo lwedrayivu kagesi lwesibili.
Iphampu kaphethiloli yohlobo lwe-diaphragm
Iphampu kaphethiloli yohlobo lwe-diaphragm imele iphampu kaphethiloli yomshini, esetshenziswa enjinini ye-carburetor, ngokuvamile eqhutshwa yisondo elingavamile ku-camshaft, isimo sayo sokusebenza siyilokhu:
① Ukujikeleza kwe-camshaft yokumunca uwoyela, lapho ingalo yokushukumisa ephezulu engavamile idonswa phansi induku yefilimu yepompo, ipompe ifilimu phansi, ikhiqize ukumunca, uphethiloli uzomuncwa ethangini, bese kuthi ngepayipi likawoyela, isihlungi sikaphethiloli, singene ekamelweni likawoyela lepompo kaphethiloli.
② Uwoyela wephampu Lapho i-eccentric ijika i-Engela ethile futhi ingasaphezi ingalo yokuxubha, isipilingi sefilimu yephampu siyanwebeka, ifilimu yephampu iyaphakama, bese uphethiloli ucindezelwa kusuka ku-valve yokuphuma kawoyela uye ekamelweni elintantayo le-carburetor.
Iphampu kaphethiloli yohlobo lwe-diaphragm ibonakala ngesakhiwo sayo esilula, kodwa ngenxa yemiphumela yokushisa kwenjini, kufanele kuqashelwe ngokukhethekile ukuqinisekisa ukusebenza kahle kukawoyela wephampu emazingeni okushisa aphezulu, kanye nokuqina kwephampu yento yerabha ekushiseni namafutha.
Ukunikezwa kukawoyela okuphezulu kwephampu kaphethiloli evamile kukhulu ngokuphindwe kabili kuya kathathu kunesilinganiso esiphezulu sokusetshenziswa kukaphethiloli kwenjini kaphethiloli. Uma uwoyela wephampu ungaphezu kokusetshenziswa kukaphethiloli futhi ivalvu yenalidi yegumbi lokuntanta le-carburetor ivaliwe, ingcindezi emgqeni wokukhipha iphampu kawoyela iyanda, isabela ephampu kawoyela, futhi ukuhamba kwe-diaphragm kuyafinyezwa noma kuyeke ukusebenza.
Iphampu kaphethiloli kagesi
Iphampu kagesi kaphethiloli, ayiqhutshwa yi-camshaft, kodwa ngamandla kagesi iphinda ifuthwe ifilimu yokufutha. Iphampu kagesi ingakhetha ngokukhululekile indawo yokufaka, futhi ingavimbela isimo sokumelana nomoya.
Izinhlobo eziyinhloko zokufakwa kwamaphampu kaphethiloli kagesi ezinjini zokujova uphethiloli zifakwa emgqeni wokuphakelwa kukaphethiloli noma ethangini likaphethiloli. Eyokuqala inokwakheka okukhulu, ayidingi ukwakheka okukhethekile kwethangi likaphethiloli, futhi kulula ukuyifaka nokuyiqaqa. Kodwa-ke, ingxenye yokumunca iphampu kaphethiloli inde, kulula ukukhiqiza ukumelana nomoya, futhi umsindo osebenzayo mkhulu, ngaphezu kwalokho, iphampu kaphethiloli akumele ivuze, futhi lolu hlobo alusetshenziswanga kakhulu ezimotweni ezintsha zamanje. Iphayiphi kaphethiloli yokugcina ilula, umsindo ophansi, izidingo zokuvuza kwamafutha amaningi aziphezulu, yinkambiso yamanje eyinhloko.
Emsebenzini, ngaphezu kokunikeza ukusetshenziswa okudingekayo ekusebenzeni kwenjini, ukugeleza kwephampu kaphethiloli kufanele futhi kuqinisekise ukuthi kukhona ukugeleza okwanele kokubuya ukuqinisekisa ukuzinza kwengcindezi yesistimu kaphethiloli kanye nokupholisa okwanele.
Yiziphi izimpawu zokwehluleka kwephampu kaphethiloli
Izimpawu zokwehluleka kwephampu kaphethiloli zifaka phakathi, kodwa azigcini nje kulokhu:
Imoto kunzima ukuyiqala futhi ingadinga ukuthungwa okuningi ukuze iqale.
Ukusheshisa kubuthakathaka, futhi imoto ayikwazi ukufakwa uphethiloli uma ishayela, noma icishe.
Injini iyazamazama bese kukhanya isibani sephutha.
Kuba nomuzwa wokukhungatheka uma usheshisa ngokushesha.
Injini inomsindo ongajwayelekile ngesikhathi sokushayela, njengomsindo wokuvungazela.
Ukusetshenziswa kukaphethiloli okungavamile, ukwanda okungenzeka.
Izimpawu zokucindezela okuphansi kuphampu kaphethiloli endala yeBora zingafaka phakathi isidingo sokushiswa okuningi ukuze imoto iqale, ukusheshisa okubuthakathaka ngenkathi ushayela, kanye nokushaqeka kwenjini okungenzeka kanye nezibani eziyinkinga. Lezi zimpawu zibonisa ukuthi iphampu kaphethiloli ingase ingakwazi ukunikeza ukucindezela okwanele kukaphethiloli, okuthinta ukusebenza okuvamile kwenjini.
Uma ufuna ukwazi okwengeziwe, qhubeka ufunda ezinye izihloko ezikulesi siza!
Sicela usishayele ucingo uma udinga imikhiqizo enjalo.
I-Zhuo Meng Shanghai Auto Co., Ltd. izibophezele ekuthengiseni izingxenye zezimoto ze-MG&MAUXS futhi wamukelekile ukuzithenga.
