impompo yepetroli
Umsebenzi wepompo yepetroli kukutsala ipetroli kwitanki yepetroli uze uyicinezele kwigumbi lokudada le-carburetor ngepayipi kunye nesihluzo sepetroli. Kungenxa yepompo yepetroli ukuba itanki yepetroli inokubekwa ngasemva kwemoto kude nenjini nangaphantsi kwenjini.
Iimpompo zepetroli zingahlulwahlulwa zibe luhlobo lwe-diaphragm oluqhutywa ngoomatshini kunye nohlobo oluqhutywa ngombane ngokweendlela ezahlukeneyo zokuqhuba.
Intshayelelo
Umsebenzi wepompo yepetroli kukutsala ipetroli kwitanki yepetroli uze uyicinezele kwigumbi lokudada le-carburetor ngepayipi kunye nesihluzo sepetroli. Kungenxa yepompo yepetroli ukuba itanki yepetroli inokubekwa ngasemva kwemoto kude nenjini nangaphantsi kwenjini.
Ulwahlulo
Iimpompo zepetroli zingahlulwahlulwa zibe luhlobo lwe-diaphragm oluqhutywa ngoomatshini kunye nohlobo oluqhutywa ngombane ngokweendlela ezahlukeneyo zokuqhuba.
Impompo yepetroli ye-diaphragm
Impompo yepetroli ye-diaphragm imele impompo yepetroli yoomatshini. Isetyenziswa kwinjini ye-carburetor kwaye ngokubanzi iqhutywa livili elingaqhelekanga kwi-camshaft. Iimeko zayo zokusebenza zezi:
① Ngexesha lokujikeleza kwe-camshaft yokufunxa ioyile, xa ivili elingaqhelekanga lityhala ingalo ye-rocker kwaye litsala intonga yokutsala i-diaphragm yepompo, i-diaphragm yepompo iyehla ukuze ivelise ukufunxa, kwaye ipetroli itsalwa kwi-tank yepetroli ize ingene kwi-pump yepetroli nge-oyile pipe, igumbi lesihluzi sepetroli.
②Ioyile yokupompa Xa ivili elingaqhelekanga lijikeleza ngekona ethile kwaye lingasayityhali ingalo yerocker, intwasahlobo yemembrane yepompo iyolula, ityhala imembrane yepompo phezulu, kwaye ipetroli ecinezelayo isuka kwivalvu yokuphuma kweoyile iye kwigumbi lokudada lekhabharetha.
Iimpompo zepetroli ze-diaphragm ziphawulwa ngesakhiwo esilula, kodwa ngenxa yokuba zichaphazeleka bubushushu benjini, kufuneka kunikwe ingqalelo ekhethekileyo ukuqinisekisa ukusebenza kokumpompa kumaqondo obushushu aphezulu kunye nokuqina kwe-diaphragm yerabha ngokuchasene nobushushu kunye neoyile.
Ngokubanzi, umbane ophezulu ofumaneka kwipompo yepetroli uphindwe kayi-2.5 ukuya kwi-3.5 kunombane ophezulu osetyenziswa kwinjini yepetroli. Xa umthamo weoyile yepompo ungaphezulu kunombane osetyenziswa kwinjini yepetroli kwaye ivalvu yenaliti kwigumbi lokudada lekhabharetha ivaliwe, uxinzelelo olukwipayipi ye-oyile yepompo yeoyile luyanda, oluthi luphendule kwipompo yeoyile, lufinyeze ukubetheka kwe-diaphragm okanye luyeke ukusebenza.
impompo yepetroli yombane
Ipompo yepetroli yombane ayixhomekekanga kwi-camshaft ukuze iqhube, kodwa ixhomekeke kumandla e-electromagnetic ukuze ifunxe i-membrane yepompo ngokuphindaphindiweyo. Olu hlobo lwepompo yombane lunokukhetha ngokukhululekileyo indawo yokufakela, kwaye lunokuthintela isiganeko sokutshixa komoya.
Iintlobo eziphambili zokufakelwa kweepompo zepetroli zombane zeenjini zokujova ipetroli zifakelwa kumbhobho wokuhambisa ioyile okanye kwitanki yepetroli. Eyokuqala inoluhlu olukhulu loyilo, ayidingi itanki yepetroli eyenzelwe ngokukodwa, kwaye kulula ukuyifaka nokuyiqhaqha. Nangona kunjalo, icandelo lokufunxa ioyile kwipompo yeoyile lide, kulula ukuvelisa ukumelana nomoya, kwaye ingxolo yokusebenza nayo inkulu kakhulu. Ukongeza, kufuneka ukuba ipompo yeoyile ingavuzi. Olu hlobo alusetyenziswa rhoqo kwizithuthi ezintsha zangoku. Eyokugqibela inemibhobho yepetroli elula, ingxolo ephantsi, kunye neemfuno eziphantsi zokuvuza kwepetroli okuninzi, okuyindlela ephambili yangoku.
Xa usebenza, izinga lokuhamba kwepompo yepetroli akufuneki libonelele kuphela ngokusetyenziswa okufunekayo ekusebenzeni kwenjini, kodwa liqinisekise nokuhamba okwaneleyo kweoyile ukuqinisekisa uzinzo loxinzelelo kunye nokupholisa okwaneleyo kwenkqubo yepetroli.
