Pompo ya mafuta.
Ntchito ya pampu yamafuta ndikutulutsa mafuta mu thanki ndikuyikankhira kudzera mu chitoliro ndi fyuluta yamafuta kupita ku chipinda choyandama cha carburetor. Chifukwa cha pampu yamafuta, thanki yamafuta imatha kuyikidwa kumbuyo kwa galimoto, kutali ndi injini, komanso pansi pa injini.
Pampu ya petulo malinga ndi njira zosiyanasiyana zoyendetsera galimoto, ikhoza kugawidwa m'magulu awiri: mtundu wa diaphragm drive ndi mtundu wachiwiri wa electric drive.

Pampu ya petulo ya mtundu wa diaphragm
Pampu yamafuta ya mtundu wa diaphragm ndi yoyimira pampu yamafuta yamakina, yomwe imagwiritsidwa ntchito mu injini ya carburetor, nthawi zambiri imayendetsedwa ndi gudumu lozungulira pa camshaft, momwe imagwirira ntchito ndi:
① Kuzungulira kwa camshaft yoyamwa mafuta, pamene mkono wogwedeza wa eccentric pamwamba, kukoka pansi ndodo ya filimu ya pampu, kupompa filimu pansi, kutulutsa kuyamwa, mafuta adzatengedwa kuchokera mu thanki, ndipo kudzera mu chitoliro cha mafuta, fyuluta ya mafuta, kupita ku chipinda cha mafuta cha pampu ya mafuta.
② Mafuta a pampu Pamene chinthu chosiyana chikusintha ngodya inayake ndipo sichikukwera pamwamba pa mkono wogwedeza, kasupe wa filimu ya pampu umatambasulidwa, filimu ya pampu imakwera, ndipo mafuta amakanikizidwa kuchokera ku valavu yotulutsira mafuta kupita ku chipinda choyandama cha carburetor.
Pampu ya petulo ya mtundu wa diaphragm imadziwika ndi kapangidwe kake kosavuta, koma chifukwa cha kutentha kwa injini, chisamaliro chapadera chiyenera kuperekedwa kuti zitsimikizire kuti mafuta a pampu akugwira ntchito bwino kutentha kwambiri, komanso kulimba kwa diaphragm ya zinthu za rabara kuti itenthe ndi mafuta.
Mafuta ambiri omwe amapezeka pa pampu yamafuta ndi ochulukirapo nthawi 2.5 mpaka 3.5 kuposa mafuta ambiri omwe injini yamafuta imamwa. Mafuta a pampu akachuluka kuposa mafuta omwe amagwiritsidwa ntchito ndipo valavu ya singano ya chipinda choyandama cha carburetor ikatsekedwa, kuthamanga kwa mpweya wa pampu yamafuta kumawonjezeka, kumayankha pa pampu yamafuta, ndipo kuyenda kwa diaphragm kumafupikitsidwa kapena kumasiya kugwira ntchito.
Pampu yamagetsi ya petulo
Pampu yamagetsi ya petulo, osati yoyendetsedwa ndi camshaft, koma ndi mphamvu yamagetsi mobwerezabwereza. Pampu yamagetsi imatha kusankha momasuka malo oikira, ndipo imatha kuletsa vuto la kukana mpweya.
Mitundu yayikulu yoyika mapampu amagetsi amafuta a injini zolowetsa mafuta imayikidwa mu mzere woperekera mafuta kapena mu thanki yamafuta. Yoyamba ili ndi kapangidwe kake kakakulu, sikufuna kapangidwe kapadera ka thanki yamafuta, ndipo ndi yosavuta kuyiyika ndikuyichotsa. Komabe, gawo loyamwa pampu yamafuta ndi lalitali, losavuta kupanga kukana mpweya, ndipo phokoso logwira ntchito ndi lalikulu, kuphatikiza apo, pampu yamafuta siyenera kutayikira, ndipo mtundu uwu sunagwiritsidwe ntchito kwambiri pamagalimoto atsopano omwe alipo. Paipi yomaliza yamafuta ndi yosavuta, phokoso lotsika, kutayikira kwamafuta ambiri sikokwera, ndiye njira yayikulu yomwe ilipo pano.
Kuntchito, kuwonjezera pa kupereka mphamvu yogwiritsira ntchito injini, kuyenda kwa pampu ya petulo kuyeneranso kuonetsetsa kuti pali mphamvu yobwerera yokwanira kuti pakhale kukhazikika kwa mphamvu ya mafuta komanso kuziziritsa kokwanira.
Kodi zizindikiro za kulephera kwa pampu ya petulo ndi ziti?
Zizindikiro za kulephera kwa pampu ya petulo ndi izi, koma sizimangokhala izi:
Galimotoyo ndi yovuta kuyiyatsa ndipo ingafunike kuyatsa kangapo kuti iyatse.
Kuthamanga kwake ndi kofooka, ndipo galimoto singathe kupatsidwa mafuta poyendetsa, kapena kuzimitsa.
Injini imagwedezeka ndipo nyali yolakwika imayatsa.
Pali kukhumudwa mukathamanga mofulumira.
Injini imakhala ndi phokoso lachilendo ikayendetsa, monga phokoso la kung'ung'udza.
Kugwiritsa ntchito mafuta molakwika, mwina kuwonjezeka.
Zizindikiro za kupanikizika kochepa mu pampu yakale ya petulo ya Bora zingaphatikizepo kufunika kwa kuyatsa kangapo kuti galimoto iyambitse, kuthamanga pang'ono poyendetsa, komanso kugwedezeka kwa injini ndi magetsi ovuta. Zizindikirozi zikusonyeza kuti pampu ya petulo singathe kupereka mphamvu yokwanira ya mafuta, zomwe zimakhudza magwiridwe antchito abwinobwino a injini.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
Zhuo Meng Shanghai Auto Co., Ltd. yadzipereka kugulitsa zida zamagalimoto za MG&MAUXS zomwe zikulandiridwa kugula.
