Kodi pampu ya petulo ya galimoto ndi chiyani?
Pampu ya petulo ya galimoto ndi gawo lofunika kwambiri pa dongosolo loperekera mafuta a galimoto. Ntchito yake yayikulu ndikutulutsa petulo mu thanki ndikuyikankhira ku chipinda choyandama cha carburetor cha injini kudzera mu payipi ndi fyuluta ya petulo. Mfundo yogwirira ntchito ya pampu ya petulo imaphatikizapo mitundu iwiri ya mtundu wa diaphragm drive ya makina ndi mtundu wa drive yamagetsi:
Pampu ya petulo ya mtundu wa diaphragm yoyendetsedwa ndi makina: Mtundu uwu wa pampu ya petulo umayendetsedwa ndi gudumu losawoneka bwino pa camshaft. Pamene camshaft ikuzungulira, mkono wogwedezeka pamwamba umakoka ndodo yokoka ya filimu ya pampu, ndipo filimu ya pampu imagwa kuti ipange kuyamwa, kuyamwa petulo kuchokera mu thanki, ndikulowa mchipinda chamafuta kudzera mu chitoliro chamafuta ndi fyuluta yamafuta. Pamene eccentric sikugwiranso dzanja, kasupe wa nembanemba ya pampu umakula ndikukankhira nembanemba ya pampu kuti ikanikizire petulo kuchokera ku valavu yotulukira kupita ku chipinda choyandama cha carburetor. Ubwino wa njira iyi ndikuti kapangidwe kake ndi kosavuta, koma kamakhudzidwa kwambiri ndi kutentha kwa injini.
Pampu yamafuta yoyendetsedwa ndi magetsi: Mtundu uwu wa pampu yamafuta sudalira camshaft, koma umadalira mphamvu yamagetsi kuti ukokere filimu yapampu mobwerezabwereza. Pampu yamagetsi imatha kusankha momasuka malo oikira, ndipo imatha kuletsa kukana kwa mpweya. Pali njira ziwiri zodziwika bwino zoyikira mapampu amafuta amagetsi: imodzi imayikidwa mu mzere woperekera mafuta, ndipo inayo imayikidwa mu thanki yamafuta. Pampu yamagetsi yomwe imayikidwa mu payipi yoperekera mafuta ndi yosavuta kuyiyika ndikuyichotsa, koma gawo loyamwa mafuta ndi lalitali komanso losavuta kukana mpweya, ndipo phokoso logwira ntchito ndi lalikulu; Pampu yamafuta yapampu yamagetsi yomwe imayikidwa mu thanki yamafuta ndi yosavuta, phokoso lotsika, ndiye chinthu chachikulu chomwe chimagwiritsidwa ntchito pano.
Mfundo yogwirira ntchito ya pampu yamafuta: pamene pampu yamafuta ikugwira ntchito, kayendedwe ka mafuta kamayenera kukwaniritsa kugwiritsidwa ntchito kwa injini komanso kufunika kwa kayendedwe ka mafuta kuti zitsimikizire kuti mphamvu ya mafuta ikukhazikika komanso kuziziritsa kokwanira. Mafuta ambiri a pampu yamafuta ndi ochulukirapo nthawi 2.5 mpaka 3.5 kuposa mafuta ambiri a injini. Mafuta a pampu akapitirira kuchuluka kwa mafuta omwe amagwiritsidwa ntchito, valavu ya singano ya chipinda choyandama cha carburetor imatsekedwa, ndipo kuthamanga kwa mzere wotulutsira mafuta kumawonjezeka, zomwe zingafupikitse kuyenda kwa diaphragm kapena kusiya kugwira ntchito.
Kukonza ndi kusintha pampu ya petulo: Pambuyo pa zaka ziwiri kapena zitatu galimoto ikugwiritsidwa ntchito, chifukwa cha dothi la mafuta ndi kuwonongeka ndi zifukwa zina, mphamvu ya pampu ya petulo ingachepe, ndipo iyenera kutsukidwa kapena kusinthidwa. Kusankha pampu yoyenera ya petulo kumakhudza kwambiri momwe injini imagwirira ntchito komanso momwe mafuta amagwiritsidwira ntchito.
Ntchito yaikulu ya pampu ya mafuta a galimoto ndikutulutsa mafuta mu thanki ndikusamutsa ku injini pambuyo pokakamizidwa kuti zitsimikizire kuti dongosolo la mafuta likhoza kupereka mafuta okhazikika. ...
Momwe mapampu a petulo amagwirira ntchito
Pampu ya mafuta nthawi zambiri imayendetsedwa ndi mota, yomwe imagwiritsa ntchito kuzunguliza kwa mota mwachangu kuti iyendetse impeller kuti izungulire, motero imapanga malo otsika mphamvu m'thupi la pampu, ndipo mafuta omwe ali mu thanki amalowa m'thupi la pampu ndikusamutsidwa kupita ku injini kudzera mu mzere wotulutsira. Pofuna kuthana ndi vuto la kuyamwa mafuta pamene mafuta ali ochepa, mota ya pampu ya mafuta imakhala ndi mphamvu inayake yochulukirapo, yomwe imatha kuwonjezera mphamvu yokha mafuta akachepa kuti zitsimikizire kuti mafuta akupitilizabe kupezeka.
Mitundu ndi mawonekedwe a mapampu a petulo
Mapampu a petulo amatha kugawidwa m'mitundu iwiri malinga ndi njira zosiyanasiyana zoyendetsera: mtundu wa diaphragm yoyendetsera makina ndi mtundu wa magetsi. Magalimoto amakono nthawi zambiri amagwiritsa ntchito mapampu amagetsi, omwe ali ndi ubwino wokhala ndi mafuta ambiri a pampu, kuthamanga kwambiri kwa pampu, kukhazikika bwino, phokoso lochepa, moyo wautali ndi zina zotero. Kuphatikiza apo, pampu yamafuta ilinso ndi ntchito zosiyanasiyana zowongolera, monga ntchito isanayambe kugwira ntchito, ntchito yogwira ntchito mwachangu, ndi zina zotero, kuti zitsimikizire kuti injini imatha kupeza mafuta okhazikika pansi pa mikhalidwe yosiyanasiyana yogwirira ntchito.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
