pompa mafuta
Ntchito ya pampu ya petulo ndikuyamwa mafuta mu thanki yamafuta ndikukankhira muchipinda choyandama cha carburetor kudzera papaipi ndi fyuluta yamafuta.Ndi chifukwa cha mpope wa petulo kuti thanki ya petulo ikhoza kuikidwa kumbuyo kwa galimoto kutali ndi injini ndi pansi pa injini.
Mapampu a petulo amatha kugawidwa mumitundu yoyendetsedwa ndi ma diaphragm ndi mtundu woyendetsedwa ndi magetsi molingana ndi njira zosiyanasiyana zoyendetsera.

Pampu ya petulo ya diaphragm
Pampu ya petulo ya diaphragm imayimira pampu yamakina yamafuta.Imagwiritsidwa ntchito mu injini ya carburetor ndipo nthawi zambiri imayendetsedwa ndi gudumu la eccentric pa camshaft.Mikhalidwe yake yogwirira ntchito ndi:
① Pakusinthasintha kwa camshaft yoyamwa mafuta, gudumu la eccentric likakankhira mkono wa rocker ndikugwetsa ndodo yapampu, diaphragm imatsika kuti ipange kuyamwa, ndipo petulo imayamwa mu thanki yamafuta ndikulowa mupope yamafuta. kudzera papaipi yamafuta, chipinda chosefera mafuta.
②Kupopa mafuta Pamene gudumu la eccentric limayenda mozungulira mbali ina ndipo silikukankhiranso mkono wa rocker, kasupe wa pampu wamadzi amatambasuka, kukankhira nembanemba ya mpope mmwamba, ndi kukakamiza mafuta kuchokera ku valve yotulutsira mafuta kupita ku chipinda choyandama cha carburetor.
Mapampu a petulo a diaphragm amadziwika ndi mawonekedwe osavuta, koma chifukwa amakhudzidwa ndi kutentha kwa injini, chidwi chapadera chiyenera kuperekedwa pakuwonetsetsa kuti kupopera kumatentha kwambiri komanso kulimba kwa diaphragm ya mphira motsutsana ndi kutentha ndi mafuta.
Nthawi zambiri, kuchuluka kwamafuta a pampu yamafuta ndi 2.5 mpaka 3.5 kuposa kuchuluka kwamafuta a injini yamafuta.Pamene kuchuluka kwa mafuta a pampu ndi kwakukulu kuposa kugwiritsira ntchito mafuta ndipo valavu ya singano m'chipinda choyandama cha carburetor ikatsekedwa, kupanikizika kwa payipi yotulutsira mafuta papampu yamafuta kumawonjezeka, komwe kumakhudzidwa ndi mpope wamafuta, kufupikitsa kugunda kwa mpweya. diaphragm kapena kuyimitsa ntchito.
pampu yamagetsi yamagetsi
Pampu yamagetsi yamagetsi sadalira camshaft kuti iyendetse, koma imadalira mphamvu yamagetsi kuti iyamwe mobwerezabwereza pampu.Pampu yamagetsi yamtunduwu imatha kusankha mwaufulu malo oyika, ndipo imatha kuletsa chodabwitsa cha loko ya mpweya.
Mitundu yayikulu yoyika mapampu amagetsi amagetsi amagetsi ojambulira mafuta amayikidwa mupaipi yamafuta kapena mu tanki yamafuta.Yoyamba ili ndi masanjidwe okulirapo, safuna tanki yamafuta opangidwa mwapadera, ndipo ndiyosavuta kuyiyika ndikuyika.Komabe, gawo loyamwa mafuta la pampu yamafuta ndi lalitali, ndilosavuta kupanga kukana kwa mpweya, ndipo phokoso logwira ntchito ndilokulirapo.Kuphatikiza apo, pamafunika kuti pampu yamafuta isatayike.Mtundu uwu sugwiritsidwa ntchito kawirikawiri m'magalimoto atsopano.Yotsirizirayi ili ndi mapaipi osavuta amafuta, phokoso lochepa, komanso zofunikira zochepa pakutha kwamafuta angapo, zomwe ndizomwe zikuchitika masiku ano.
Pogwira ntchito, kuthamanga kwa pampu ya petulo sikuyenera kungopereka zomwe zimafunikira kuti zigwiritsidwe ntchito pa injini, komanso kuonetsetsa kuti mafuta akuyenda bwino kuti atsimikizire kukhazikika kwamphamvu komanso kuzizira kokwanira kwamafuta.
