Impompo yepetroli.
Umsebenzi wepompo yepetroli kukutsala ipetroli etankini uze uyicinezele ngepayipi kunye nesihluzo sepetroli ukuya kwigumbi lokudada lekhabharetha. Kungenxa yepompo yepetroli ukuba itanki yepetroli inokubekwa ngasemva kwemoto, kude nenjini, nangaphantsi kwenjini.
Impompo yepetroli ngokwendlela eyahlukileyo yokuqhuba, ingahlulwahlulwa ibe yi-diaphragm yokuqhuba ngoomatshini kunye ne-electric drive uhlobo lwesibini.
Impompo yepetroli yohlobo lwe-diaphragm
Impompo yepetroli yohlobo lwe-diaphragm imele ipompo yepetroli yoomatshini, esetyenziswa kwinjini ye-carburetor, ngokubanzi iqhutywa livili elingaqhelekanga kwi-camshaft, imeko yayo yokusebenza yile:
① Ukujikeleza kwe-camshaft yokufunxa ioyile, xa ingalo yokushukumisa ephezulu ingaqhelekanga, itsalwa intonga yefilimu yepompo, ipompe ifilimu phantsi, ivelise ukufunxa, ipetroli iya kutsalwa etankini, ize idlule kumbhobho weoyile, ihluze ipetroli, iye kwigumbi leoyile lepompo yepetroli.
② Ioyile yepompo Xa i-eccentric ijika i-Engile ethile kwaye ingasasebenzi phezu kwengalo yokushukumisa, intwasahlobo yefilimu yepompo iyolulwa, ifilimu yepompo iyaphakama, kwaye ipetroli icinezelwe ukusuka kwivalvu yokuphuma kweoyile ukuya kwigumbi lokudada lekhabharetha.
Ipompo yepetroli yohlobo lwe-diaphragm ibonakaliswa bulwakhiwo lwayo olulula, kodwa ngenxa yefuthe lobushushu benjini, kufuneka kunikwe ingqalelo ekhethekileyo ekuqinisekiseni ukusebenza kweoyile yepompo kumaqondo obushushu aphezulu, kunye nokuqina kwe-diaphragm yento yerabha ukuya kubushushu nakwioyile.
Ubuninzi beoyile kwipompo yepetroli eqhelekileyo bukhulu ngokuphindwe kayi-2.5 ukuya kwi-3.5 kunobuninzi beoyile esetyenzisiweyo kwinjini yepetroli. Xa ioyile yepompo ingaphezulu kunobungakanani beoyile esetyenzisiweyo kwaye ivalvu yenaliti yegumbi lokudada le-carburetor ivaliwe, uxinzelelo kumgca wokuphuma kwepompo yeoyile luyanda, lusabela kwipompo yeoyile, kwaye ukuhamba kwe-diaphragm kuyafinyezwa okanye kuyeke ukusebenza.
Impompo yepetroli yombane
Impompo yepetroli yombane, ayiqhutywa yi-camshaft, kodwa ngamandla e-electromagnetic iphindaphinda ifilimu yempompo yokufunxa. Impompo yombane inokukhetha ngokukhululekileyo indawo yokufakela, kwaye inokuthintela isiganeko sokuxhathisa umoya.
Iintlobo eziphambili zokufakelwa kweempompo zepetroli zombane zeenjini zokujova ipetroli zifakelwa kumgca wokubonelela ngeoyile okanye kwitanki yepetroli. Eyokuqala inoyilo olukhulu, ayifuni uyilo olukhethekileyo lwetanki yepetroli, kwaye kulula ukuyifaka nokuyiqhaqha. Nangona kunjalo, icandelo lokufunxa ipompo yeoyile lide, kulula ukuvelisa ukumelana nomoya, kwaye ingxolo yokusebenza inkulu, ukongeza, ipompo yeoyile akufuneki ivuze, kwaye olu hlobo alusetyenziswanga kakhulu kwizithuthi ezintsha zangoku. Umbhobho wamafutha wokugqibela ulula, ingxolo ephantsi, iimfuno zokuvuza kwamafutha amaninzi aziphezulu, yeyona ndlela iphambili yangoku.
Emsebenzini, ukongeza ekunikezeni ukusetyenziswa okufunekayo ekusebenzeni kwenjini, ukuhamba kwepompo yepetroli kufuneka kuqinisekise ukuba kukho ukuhamba okwaneleyo kokubuya ukuqinisekisa uzinzo loxinzelelo lwenkqubo yepetroli kunye nokupholisa okwaneleyo.
Yeyiphi impawu ephulwe yipompo yepetroli
1. Ubunzima bokuqalisa injini: Olu lolona phawu luqhelekileyo lokungasebenzi kakuhle kwepompo yepetroli, kuba ipompo yepetroli ayikwazi ukusebenza ngokuqhelekileyo, nto leyo ebangela ukungabikho kwamafutha aneleyo, kwaye imoto ngokwemvelo kunzima ukuyiqalisa.
2. Ukutshaya umlilo ngexesha lokuqhuba: Ngenxa yokunikezelwa kwepetroli okungazinzanga, imoto inokutsha ngequbuliso ngexesha lokuqhuba.
3. Ukusetyenziswa kwepetroli okwandileyo: Ukuba ipompo yepetroli ayisebenzi, imoto ingasebenzisa ipetroli eninzi ukuhlangabezana neemfuno eziqhelekileyo zokusebenza.
4. Ukusebenza kwenjini okunciphileyo: Ngenxa yokunikezelwa kwamafutha okungazinzanga, ukusebenza kokukhawulezisa kunye nesantya esiphezulu semoto kunokuchaphazeleka.
5. Isibane sesilumkiso sedeshibhodi sivuliwe: ukungasebenzi kakuhle kwepompo yepetroli kwezinye izithuthi kuya kubangelwa sisibane sesilumkiso sedeshibhodi.
Umgaqo wokusebenza wepompo yepetroli
1, umgaqo wepompo yepetroli kukutsala ipetroli etankini, kwaye idlule kwipayipi kunye noxinzelelo lwefiltha yepetroli ukuya kwigumbi lokudada le-carburetor. Kungenxa yepompo yepetroli ukuba itanki yepetroli inokubekwa ngasemva kwemoto, kude nenjini, nangaphantsi kwenjini. Ipompo yepetroli yombane, ayiqhutywa yi-camshaft, kodwa ngamandla e-electromagnetic ngokuphindaphindiweyo ifilimu yepompo yokufunxa.
2, umgaqo wepompo yepetroli kukufunxa ipetroli etankini kunye noxinzelelo oludlula kwipayipi kunye nesihluzo sepetroli ukuya kwigumbi lokudada le-carburetor. Oku kulandelayo yinxalenye yokungeniswa kwepompo yepetroli: Kungenxa yepompo yepetroli ukuba itanki yepetroli inokubekwa kude nenjini yemoto ize ibe ngaphantsi kunenjini.
3, umgaqo wepompo yepetroli kukutsala ipetroli ekwitanki yemoto uze uyithumele kwigumbi lokudada le-carburetor ngepayipi kunye nesihluzo sepetroli. Ngenxa yepompo yepetroli, itanki yepetroli yemoto inokubekwa ngasemva kwemoto, kude nenjini kwaye ibe ngaphantsi kunenjini. Ipompo yepetroli yombane ayiqhutywa yi-camshaft, kodwa amandla e-electromagnetic adla ngokutsala ifilimu yepompo.
1. Uxinzelelo olugqithisileyo lwepompo yepetroli luya kutshabalalisa iimeko zokuthambisa eziqhelekileyo. Njengokuba i-oyile i-viscosity inkulu kakhulu, i-metamorphic gelatinization, i-filter element kunye ne-oyile passage blockage, ukulungiswa komlawuli woxinzelelo okanye ukungavulwa kuya kubangela uxinzelelo oluphezulu lweoyile.
2, ukuguguleka kwe-impeller yepompo ye-centrifugal: uxinzelelo lwe-oyile luyancitshiswa, ukukhawulezisa kubuthathaka. Ukuguguleka kwebrashi yekhabhoni: Ipompo yepetroli iyayeka, ayikwazi ukuqala, kule meko ingabetha ezantsi kwetanki, ipompo isakwazi ukusebenza. Ukusilela koomatshini okufana nokunamathela kwe-rotor: umsinga osebenzayo wepompo yeoyile uyaphakama, nto leyo ebangela umonakalo kwi-relay okanye kwi-inshurensi.
3, izizathu eziphambili zokungazinzi koxinzelelo lwepetroli yeemoto zezi: umonakalo womlawuli woxinzelelo lwepetroli kwimpompo yepetroli, ukuvaleka kwepompo yepetroli okwaneleyo kwi-oyile yepompo okanye isihluzi seoyile, ukudibana kwesekethe nesixhobo sesihluzi sepetroli esibi okanye ukuvaleka kombhobho wepetroli. Uxinzelelo lwepetroli aluzinzanga, kwaye impembelelo emotweni ikakhulu kukuba isantya sokungaqhubi kakuhle asizinzanga, kwaye icandelo lokusebenza kwenjini libuthathaka ukukhawulezisa. Ndiyathemba ukuba ukufumene kuluncedo.
4, uxinzelelo lweoyile luphantsi kakhulu: umonakalo kwimpompo yeoyile, ukunqongophala kweoyile kwimpompo, umlawuli woxinzelelo lweoyile.
