impompo yepetroli
Umsebenzi wempompo yepetroli kukufunxa i-petroli ngaphandle kwetanki yamafutha kwaye uyicinezele kwigumbi lokudada lekhabhuretha ngombhobho kunye nesihluzo sepetroli. Kungumbulelo kwimpompo yepetroli ukuba itanki yepetroli ibekwe ngasemva kwemoto kude ne-injini nangaphantsi kwe-injini.
Iimpompo zepetroli zinokwahlulwa zibe luhlobo lwediaphragm oluqhutywa ngoomatshini kunye nohlobo oluqhutywa ngombane ngokweendlela ezahlukeneyo zokuqhuba.
Intshayelelo
Umsebenzi wempompo yepetroli kukufunxa i-petroli ngaphandle kwetanki yamafutha kwaye uyicinezele kwigumbi lokudada lekhabhuretha ngombhobho kunye nesihluzo sepetroli. Kungumbulelo kwimpompo yepetroli ukuba itanki yepetroli ibekwe ngasemva kwemoto kude ne-injini nangaphantsi kwe-injini.
Ukuhlelwa
Iimpompo zepetroli zinokwahlulwa zibe luhlobo lwediaphragm oluqhutywa ngoomatshini kunye nohlobo oluqhutywa ngombane ngokweendlela ezahlukeneyo zokuqhuba.
Impompo yepetroli yeDiphragm
Ipompo yepetroli yeDiphragm imele impompo yepetroli yoomatshini. Isetyenziswa kwi-injini ye-carburetor kwaye ngokubanzi iqhutywa livili le-eccentric kwi-camshaft. Iimeko zayo zokusebenza zezi:
① Ngexesha lokujikeleza kwecamshaft yokufunxa ioyile, xa ivili le-eccentric lityhala ingalo ye-rocker kwaye ikhuphe intonga yokutsala i-oyile, i-diaphragm yempompo iyehla ikhuphe ukufunxa, kwaye i-petroli ikhutshiwe kwitanki yamafutha kwaye ingene kwimpompo yepetroli. ngombhobho weoyile, igumbi lokucoca ipetroli.
②I-oyile yokumpompa Xa ivili le-eccentric lijikeleza nge-engile ethile kwaye lingasayityhali ingalo yerocker, intwasahlobo yembrane yempompo iyolula, ityhala i-membrane yempompo phezulu, kunye noxinzelelo lwepetroli ukusuka kwivalve yokuphuma yeoli ukuya kwigumbi elidadayo le-carburetor.
Iipompo zepetroli ze-diaphragm zibonakaliswe ngesakhiwo esilula, kodwa ngenxa yokuba zichatshazelwa kubushushu be-injini, ingqwalasela ekhethekileyo kufuneka ihlawulwe ekuqinisekiseni ukusebenza kokupompa kumaqondo aphezulu kunye nokuqina kwe-diaphragm yerabha ngokuchasene nokushisa kunye neoli.
Ngokuqhelekileyo, ukunikezelwa kwamafutha aphezulu kwipompo yepetroli ngama-2.5 ukuya ku-3.5 amaxesha amakhulu kunobuninzi bokusetyenziswa kwamafutha enjini yepetroli. Xa umthamo weoyile yempompo mkhulu kunokusetyenziswa kwamafutha kunye nevalve yenaliti kwigumbi lokudada lekhabhuretha ivaliwe, uxinzelelo kumbhobho ophumayo wempompo yeoyile luyenyuka, oluthi luchaphazele impompo yeoyile, lucuthe ukubetha kwe-oyile. i-diaphragm okanye ukuyeka umsebenzi.
impompo yepetroli yombane
Ipompo yepetroli yombane ayithembeli kwi-camshaft ukuqhuba, kodwa ixhomekeke kumandla ombane we-electromagnetic ukumunca ngokuphindaphindiweyo i-membrane yempompo. Olu hlobo lwempompo yombane lunokukhetha ngokukhululekileyo indawo yofakelo, kwaye lunokuthintela ukutshixa umoya.
Iintlobo eziphambili zokufakela iimpompo zepetroli zombane kwiinjini ze-injection ye-petroli zifakwe kwipayipi ye-oyile okanye kwitanki yepetroli. Eyangaphambili inoluhlu olubanzi loyilo, ayifuni itanki yepetroli eyenzelwe ngokukodwa, kwaye kulula ukuyifaka kunye nokuqhaqha. Nangona kunjalo, icandelo lokufunxa i-oyile yempompo yeoli lide, kulula ukuvelisa ukuxhathisa umoya, kwaye ingxolo yokusebenza nayo inkulu kakhulu. Ukongeza, kuyafuneka ukuba impompo yeoli mayingavuzi. Olu hlobo alufane lusetyenziswe kwiimoto ezintsha zangoku. Le yokugqibela inemibhobho yepetroli elula, ingxolo ephantsi, kunye neemfuno ezisezantsi zokuvuza kwamafutha amaninzi, eyona ndlela iphambili yangoku.
Xa usebenza, izinga lokuhamba kwepompo yepetroli akufanele libonelele kuphela ukusetyenziswa okufunekayo ekusebenzeni kwe-injini, kodwa kwakhona kuqinisekiswe ukuhamba okwaneleyo kokubuyisela ioli ukuze kuqinisekiswe ukuzinza koxinzelelo kunye nokupholisa okwaneleyo kwenkqubo yamafutha.
