Impompo yepetroli.
Umsebenzi wepompo yepetroli kukufunxa i-petroli ngaphandle kwetanki kwaye uyicinezele ngombhobho kunye nesihluzo sepetroli kwigumbi lokudada le-carburetor. Kungenxa yempompo yepetroli eyenza ukuba itanki yepetroli ibekwe ngasemva kwemoto, kude ne-injini, nangaphantsi kwe-injini.
Impompo yepetroli ngokwendlela eyahlukileyo yokuqhuba, inokwahlulwa ibe yi-mechanical drive diaphragm type kunye ne-electric drive type ezimbini.
Ipompo yepetroli yodidi lweDiphragm
Ipompo yepetroli yohlobo lwe-diaphragm ngummeli wempompo yepetroli yomatshini, esetyenziswa kwi-injini ye-carburetor, eqhutywa ngokubanzi livili le-eccentric kwi-camshaft, imeko yayo yokusebenza yile:
① Ukujikeleziswa kwe-oyile yokufunxa icamshaft, xa umphezulu we-eccentric ungcangcazela ingalo, utsale intonga yempompo yempompo, ifilimu impompe phantsi, ivelise ukufunxa, i-petroli iya kutsalwa etankini, kwaye ngombhobho weoyile, isihluzo sepetroli, singene kwigumbi leoli. impompo yepetroli.
② I-oyile yepompo Xa i-eccentric ijika i-Angle ethile kwaye ingasayi kuphakamisa ingalo yokugubha, i-spring yefilimu yepompo isoluliwe, ifilimu yepompo iphakama, kwaye i-petroli icinezelwe ukusuka kwi-valve yokuphuma kweoli ukuya kwigumbi lokudada le-carburetor.
Ipompo yepetroli yohlobo lwe-diaphragm ibonakaliswe ngesakhiwo sayo esilula, kodwa ngenxa yefuthe lobushushu le-injini, ingqwalasela ekhethekileyo kufuneka ihlawulwe ekuqinisekiseni ukusebenza kweoyile yempompo kumaqondo aphezulu obushushu, kunye nokuqina kwe-diaphragm yezinto zerabha ukutshisa kunye ioli.
Ukunikezelwa kweoli ephezulu yepompo yepetroli jikelele ngama-2.5 ukuya ku-3.5 amaxesha amakhulu kunobuninzi bokusetyenziswa kwamafutha enjini yepetroli. Xa i-oyile yepompo inkulu kunokusetyenziswa kwamafutha kunye ne-valve yenaliti ye-carburetor float chamber ivaliwe, uxinzelelo kumgca wokuphuma kwepompo yeoli luyanda, lusabela kwipompo yeoli, kwaye ukuhamba kwe-diaphragm kufutshane okanye ukuyeka ukusebenza.
Impompo yepetroli yombane
Impompo yepetroli yombane, engaqhutywa yicamshaft, kodwa ngamandla ombane ophindaphinda ifilimu yokufunxa impompo. Ipompo yombane inokukhetha ngokukhululekileyo indawo yokufakela, kwaye inokuthintela ukwenzeka kokumelana nomoya.
Iintlobo eziphambili zokufakela iimpompo zepetroli zombane kwiinjini ze-injection ye-petroli zifakwe kumgca we-oyile okanye kwi-tank ye-petroli. Eyangaphambili inesakhiwo esikhulu, ayifuni ukuyila okukhethekileyo kwetanki yepetroli, kwaye kulula ukuyifaka kunye nokuqhaqha. Nangona kunjalo, icandelo lokufunxa i-oyile yepompo lide, kulula ukuvelisa ukuchasana komoya, kwaye ingxolo esebenzayo inkulu, ngaphezu koko, ipompo yeoli ayifuni ukuvuza, kwaye olu hlobo lusetyenziswe kancinci kwizithuthi ezitsha zangoku. Umbhobho wepetroli wokugqibela ulula, ingxolo ephantsi, iimfuno zokuvuza kwamafutha amaninzi aziphezulu, yeyona ndlela iphambili yangoku.
Emsebenzini, ngaphezu kokubonelela ngokusetyenziswa okufunekayo ekusebenzeni kwe-injini, ukuhamba kwepompo yepetroli kufuneka kwakhona kuqinisekise ukuba kukho ukubuya okwaneleyo kokubuyisela ukuqinisekisa ukuzinza koxinzelelo lwenkqubo yamafutha kunye nokupholisa okwaneleyo.
Luluphi uphawu oluphuphumayo lwempompo yepetroli
1. Ubunzima bokuqala kwe-injini: Le yimbonakaliso eqhelekileyo yokungaphumeleli kwepompo yepetroli, kuba ipompo yepetroli ayikwazi ukusebenza ngokuqhelekileyo, okubangelwa ukunikezelwa kwepetroli okwaneleyo, kwaye isithuthi sinzima ngokwemvelo ukuqala.
2. Ukuvutha komlilo ngexesha lokuqhuba: Ngenxa yonikezelo lwamafutha olungazinzanga, isithuthi sinokuvutha ngequbuliso ngexesha lokuqhuba.
3. Ukunyuka kokusetyenziswa kwamafutha: Ukuba impompo yepetroli iyasilela, imoto inokusebenzisa amafutha amaninzi ukuhlangabezana neemfuno eziqhelekileyo zokusebenza.
4. Ukunciphisa ukusebenza kwe-injini: Ngenxa yokunikezelwa kwamafutha okungazinzanga, ukusebenza ngokukhawuleza kunye nesantya esiphezulu semoto kunokuchaphazeleka.
5. Isibane sesilumkiso sedeshibhodi sivuliwe: ukusilela kwempompo yamafutha kwezinye izithuthi kuya kuqhutywa sisibane sesilumkiso sedeshibhodi.
Umgaqo wokusebenza wepompo yepetroli
1, umgaqo wempompo yepetroli kukufunxa i-petroli ngaphandle kwetanki, kwaye ngombhobho kunye noxinzelelo lokucoca i-petroli kwigumbi lokudada le-carburetor. Kungenxa yempompo yepetroli eyenza ukuba itanki yepetroli ibekwe ngasemva kwemoto, kude ne-injini, nangaphantsi kwe-injini. Impompo yepetroli yombane, engaqhutywa yicamshaft, kodwa ngamandla ombane ophindaphinda ifilimu yokufunxa impompo.
I-2, umgaqo wepompo yepetroli kukufunxa i-petroli kwitanki kunye noxinzelelo ngombhobho kunye nesihluzo sepetroli kwigumbi lokudada le-carburetor. Oku kulandelayo yinxalenye yokuqaliswa kwepompo yepetroli: Kungenxa yempompo yepetroli ukuba itanki yepetroli inokubekwa kude ne-injini yemoto kwaye iphantsi kune-injini.
3, umgaqo wempompo yepetroli kukufunxa i-petroli kwitanki yemoto kwaye uyithumele kwigumbi lokudada le-carburetor ngombhobho kunye nesihluzo sepetroli. Ngenxa yempompo yepetroli, itanki yamafutha yemoto inokubekwa ngasemva kwimoto, kude ne-injini kwaye ingaphantsi kune-injini. Ipompo yepetroli yombane ayiqhutywa yi-camshaft, kodwa amandla e-electromagnetic aphindaphinda ifilimu yepompo.
1. Uxinzelelo olugqithisileyo lwepompo yepetroli luya kutshabalalisa iimeko eziqhelekileyo zokuthambisa. Okufana ne-oil viscosity inkulu kakhulu, i-gelatinization ye-metamorphic, i-filter element kunye ne-oil passage blockage, ukulungiswa kwe-pressure regulator okanye ayikwazi ukuvulwa kuya kubangela uxinzelelo lweoli ephezulu.
I-2, i-centrifugal pump impeller wear: uxinzelelo lwe-oyile luyancipha, ukukhawuleza kubuthathaka. Ukunxiba kwebrashi yeCarbon: Impompo yepetroli iyayeka, ayinakuqala, kule meko inokubetha emazantsi etanki, impompo isenokuqhuba. Ukungaphumeleli komatshini okufana ne-rotor ibambekile: ukusebenza kwangoku kwepompo yeoli kuyenyuka, kubangela umonakalo kwi-relay okanye i-inshurensi.
I-3, izizathu eziphambili zokungazinzi koxinzelelo lwe-automotive fuel: umonakalo wokulawula uxinzelelo lwe-fuel kwimpompo yamafutha, ukungonelanga kweoli yepompo okanye i-oil filter screen blockage ye-fuel fuel, uqhagamshelwano lwesekethe kunye ne-fuel filter element okanye i-fuel pipe blockage. Uxinzelelo lwepetroli aluzinzile, kwaye impembelelo kwimoto ikakhulu isantya esingasebenziyo asizinzanga, kwaye isebe lokusebenza kwe-injini libuthathaka ukukhawulezisa. Ndiyathemba ukuba uyifumene iluncedo.
I-4, uxinzelelo lweoyile luphantsi kakhulu: umonakalo wempompo yeoli, ukunqongophala kweoyile yepompo, isilawuli soxinzelelo lweoyile.
