Iphampu likaphethiloli.
Umsebenzi wepompo likaphethiloli ukumunca uphethiloli ethangini bese uwucindezela ngepayipi kanye nesihlungi sikaphethiloli egumbini lokuntanta le-carburetor. Kungenxa yephampu kaphethiloli okwenza ithangi likaphethiloli libekwe ngemuva kwemoto, kude nenjini, nangaphansi kwenjini.
Iphampu kaphethiloli ngokuya ngemodi yokushayela ehlukile, ingahlukaniswa ngohlobo lwe-diaphragm yemishini kanye nohlobo lwe-electric drive.
Iphampu kaphethiloli yohlobo lwe-diaphragm
Iphampu kaphethiloli yohlobo lwe-Diaphragm imele iphampu kaphethiloli engumshini, esetshenziswa enjinini ye-carburetor, evame ukushayelwa isondo le-eccentric ku-camshaft, isimo sayo sokusebenza sithi:
① Ukushintshwa kwe-camshaft yokumunca uwoyela, lapho i-eccentric top inyakazisa ingalo, idonsela phansi i-pump film rod, futha ifilimu phansi, ikhiqize ukumunca, uphethiloli uzomuncwa ethangini, futhi ngepayipi likawoyela, isihlungi sikaphethiloli, ungene egumbini likawoyela iphampu kaphethiloli.
② Uwoyela wepompo Uma i-eccentric iphenduka i-Angle ethile futhi ingasaphakamisi ingalo yokunyakazisa, isiphethu sefilimu yepompo siyelulelwa, ifilimu yepompo iyakhuphuka, futhi uphethiloli ucindezelwa ukusuka ku-valve yokukhipha uwoyela kuya egumbini lokuntanta le-carburetor.
Iphampu kaphethiloli yohlobo lwe-diaphragm ibonakala ngesakhiwo sayo esilula, kodwa ngenxa yemiphumela eshisayo yenjini, ukunakwa okukhethekile kufanele kukhokhwe ukuze kuqinisekiswe ukusebenza kukawoyela wephampu emazingeni okushisa aphezulu, kanye nokuqina kwe-diaphragm yezinto zenjoloba ekushiseni nasekushiseni. amafutha.
Ukunikezwa kukawoyela okuphezulu kwephampu kaphethiloli jikelele kuyizikhathi ezi-2.5 kuye kwezingu-3.5 ezinkulu kunokusetshenziswa okuphezulu kukaphethiloli wenjini kaphethiloli. Lapho uwoyela wepompo mkhulu kunokusetshenziswa kukaphethiloli futhi i-valve yenaliti yegumbi lokuntanta le-carburetor ivaliwe, ingcindezi emgqeni wokuphuma kwepompo kawoyela iyanda, isabela kupompo likawoyela, futhi ukuhamba kwe-diaphragm kufinyezwa noma kuyeka ukusebenza.
Iphampu likaphethiloli kagesi
Iphampu kaphethiloli kagesi, engashayelwa i-camshaft, kodwa ngamandla kazibuthe kagesi okuphindaphinda ifilimu yepompo yokumunca. Iphampu kagesi ingakhetha ngokukhululekile indawo yokufaka, futhi ingavimbela into yokumelana komoya.
Izinhlobo eziyinhloko zokufakwa kwamaphampu kaphethiloli kagesi wezinjini zomjovo kaphethiloli zifakwa kulayini wokuphakela uwoyela noma ethangini likaphethiloli. Eyokuqala inesakhiwo esikhulu, ayidingi umklamo okhethekile wethangi likaphethiloli, futhi kulula ukuyifaka nokuhlakaza. Kodwa-ke, isigaba sokudonsa ipompo likawoyela side, kulula ukukhiqiza ukumelana komoya, futhi umsindo osebenzayo mkhulu, ngaphezu kwalokho, ipompo likawoyela akufanele livuze, futhi lolu hlobo lusetshenziswe kancane ezimotweni ezintsha zamanje. Ipayipi lakamuva likaphethiloli lilula, umsindo ophansi, izidingo zokuvuza kwamafutha amaningi aziphezulu, iwona mkhuba wamanje oyinhloko.
Emsebenzini, ngaphezu kokuhlinzeka ukusetshenziswa okudingekayo ekusebenzeni kwenjini, ukugeleza kwepompo likaphethiloli kufanele futhi kuqinisekise ukuthi kukhona ukugeleza okwanele kokubuyisela ukuze kuqinisekiswe ukuzinza kwengcindezi yesistimu kaphethiloli kanye nokupholisa okwanele.
Iluphi uphawu lapho iphampu kaphethiloli iphuka
1. Ubunzima bokuqalisa injini: Lokhu ukubonakaliswa okuvame kakhulu kokuhluleka kwepompo likaphethiloli, ngoba iphampu kaphethiloli ayikwazi ukusebenza ngokujwayelekile, okuholela ekunikezeni uphethiloli okwanele, futhi imoto inzima ngokwemvelo ukuyiqala.
2. Ukuvutha komlilo ngesikhathi sokushayela: Ngenxa yokungahlali kahle kukaphethiloli, imoto ingase ishe kungazelelwe lapho ushayela.
3. Ukwenyuka kokusetshenziswa kukaphethiloli: Uma iphampu kaphethiloli ihluleka, imoto ingase idle uphethiloli owengeziwe ukuze ihlangabezane nezidingo ezivamile zokusebenza.
4. Ukusebenza kwenjini okuncishisiwe: Ngenxa yokunikezwa kukaphethiloli okungazinzile, ukusebenza kokusheshisa kanye nesivinini esiphezulu semoto kungathinteka.
5. Ilambu lesexwayiso ledeshibhodi livuliwe: ukwehluleka kwephampu yamafutha kwezinye izimoto kuzobangelwa ilambu eliyisixwayiso ledeshibhodi.
Isimiso sokusebenza sephampu kaphethiloli
1, umgomo wephampu kaphethiloli ukumunca uphethiloli ethangini, futhi ngepayipi kanye nokucindezela kwesihlungi sikaphethiloli egumbini lokuntanta le-carburetor. Kungenxa yephampu kaphethiloli okwenza ithangi likaphethiloli libekwe ngemuva kwemoto, kude nenjini, nangaphansi kwenjini. Iphampu kaphethiloli kagesi, engashayelwa i-camshaft, kodwa ngamandla kazibuthe kagesi okuphindaphinda ifilimu yepompo yokumunca.
2, umgomo wepompo likaphethiloli ukumunca uphethiloli ethangini kanye nokucindezela ngepayipi nesihlungi sikaphethiloli egumbini lokuntanta le-carburetor. Lokhu okulandelayo kuyingxenye yokwethulwa kwephampu kaphethiloli: Kungenxa yepompo likaphethiloli ukuthi ithangi likaphethiloli lingabekwa kude nenjini yemoto futhi libe phansi kunenjini.
3, umgomo wepompo likaphethiloli ukumunca uphethiloli ethangini lemoto bese uwuthumela egumbini lokuntanta le-carburetor ngepayipi kanye nesihlungi sikaphethiloli. Ngenxa yepompo likaphethiloli, ithangi likaphethiloli lemoto lingabekwa ngemuva kwemoto, kude nenjini futhi libe ngaphansi kunenjini. Iphampu kaphethiloli kagesi ayishayelwa i-camshaft, kodwa amandla kazibuthe kagesi amunca ifilimu yepompo ngokuphindaphindiwe.
1. Ukucindezela okukhulu kwepompo likaphethiloli kuzobhubhisa izimo ezivamile zokugcoba. Okufana ne-viscosity kawoyela inkulu kakhulu, i-gelatinization ye-metamorphic, isici sokuhlunga kanye nokuvinjelwa kwamaphaseji kawoyela, ukulungiswa kwesilawuli sokucindezela noma akukwazi ukuvulwa kuzodala umfutho ophakeme kawoyela.
I-2, i-centrifugal pump impeller wear: ingcindezi yokunikezwa kukawoyela iyancipha, ukusheshisa kubuthakathaka. Ukugqokwa kwebhulashi le-Carbon: Ipompo likaphethiloli liyama, alikwazi ukuqala, kulokhu lingashaya phansi ethangini, iphampu isengakwazi ukusebenza. Ukwehluleka kwemishini njengokunamathela kwe-rotor: amandla okusebenza epompo kawoyela ayakhuphuka, abangele ukulimala kokudluliswa kwemali noma umshwalense.
I-3, izizathu eziyinhloko zokungazinzi kwengcindezi kaphethiloli wezimoto yilezi: ukulimala kwesilawuli sokucindezela uphethiloli kwipompo likaphethiloli, uwoyela wepompo onganele noma ukuvinjwa kwesikrini sesihlungi sikawoyela sepompo likaphethiloli, ukuthintana kwesekethe nesici esingesihle sesihlungi sikaphethiloli noma ukuvinjwa kwepayipi likaphethiloli. Umfutho kaphethiloli awuzinzile, futhi umthelela wemoto ngokuyinhloko ijubane lokungenzi lutho alizinzile, futhi umnyango wokusebenza kwenjini awunamandla ukuze usheshe. Ngethemba ukuthi ukuthole kuwusizo.
I-4, ingcindezi kawoyela iphansi kakhulu: ukulimala kwepompo likawoyela, ukushoda kukawoyela wepompo, isilawuli sokucindezela uwoyela.
