Pampu yamagalimoto ndi chiyani
Pampu yamagetsi pampu ndi gawo lofunikira pazinthu zamagetsi zamagetsi. Ntchito yake yayikulu ndikuyamwa mafuta kuchokera mu thankiyo ndikumukanikizani ku carburetor tort chipinda cha injini kudzera pa mapaipi ndi fyuluta ya mafuta. Mfundo yogwira ntchito pampu yamafuta imaphatikizapo mitundu iwiri yamakina a diaphragm ndi mtundu wamagetsi:
Makina oyendetsedwa ndi diaphragm mtundu mafuta phula: pampu iyi yamatumbo imayendetsedwa ndi gudumu la eccentric pamwamba pa camshaft. Pamene camsaft imazungulira, mkono wapamwamba wogwedezeka amakoka ndodo ya filimu, ndipo filimu yampu imagwera kuti ituluke, ndikuyamwa mafuta m'chiuno, ndikupanga fyuluta yamafuta ndi fyuluta yamafuta. Pamene eccentric sakulumira mkono, kampu ya kampu imafalikira ndikuyika mulu wa mutu kuti akanikizire mafuta kuchokera ku chipinda chofutirira to carbaat m'chipinda chofutira. Ubwino wa njirayi ndikuti mawonekedwe ndi osavuta, koma amakhudzidwa kwambiri ndi kutentha kwa injini.
Pampu yoyendetsedwa ndi mafuta a mafuta opopera: mpweya wamtunduwu sudalira kampu, koma pamtengowo umadalira mphamvu yamagetsi kuti ikoke mobwerezabwereza. Pup yamagetsi imatha kusankha mwaufulu kukhazikitsa, ndipo imatha kuletsa kukana mpweya. Pali njira ziwiri zogwiritsira ntchito mapampu a petulo: imodzi imayikidwa mu mzere wamafuta, ndipo winayo adayikidwa mu thanki ya mafuta. Mpukutu yamagetsi yokhazikitsidwa mu dipi la mafuta ndiosavuta kukhazikitsa ndikusinthana, koma gawo loikika lamafuta ndi lalitali komanso losavuta kukhazikika kwa mpweya, ndipo phokoso lantchito ndi lalikulu; Mapaipi yamagetsi yamagetsi yokhazikitsidwa mu thanki ya mafuta ndi yosavuta, phokoso lotsika, ndiye akuyamba.
Mfundo yogwira ntchito pampu mafuta: pomwe pampu ya mafuta ikugwira ntchito, yotuluka imafunikira kukwaniritsa ntchito ya injini ndikufuna kuti mafuta abwerere kukhazikika kwa dongosolo la mafuta komanso kuzizira kokwanira. Kuchuluka kwa mafuta kwapampu ya mafuta ndi 2,5 mpaka 3.5 mpaka 3.5 kokulirapo kuposa kuphika kwa mafuta. Mafuta ampipi ndi akulu kuposa momwe mafuta ogwiritsira ntchito amagetsi amatseka chipinda cha carbare, ndipo kupsinjika kwa mzere wamafuta kumachulukitsa, komwe kumachepetsa kuyenda kwa diaphragm kapena kusiya kugwira ntchito.
Kusamalira ndi kusintha kwa pampu yamafuta: patatha zaka ziwiri kapena zitatu kugwiritsa ntchito galimoto, chifukwa cha utoto wamafuta ndi kuvala ndi zifukwa zina, pampu ya mafuta amatha kutsukidwa kapena kusinthidwa. Kusankha pampu yoyenera ya mafuta ali ndi chofunikira kwambiri pakugwira ntchito kwa injini ndi mafuta.
Gawo lalikulu la pampu yamagetsi ndikuyamwa mafuta kuchokera mu thankiyo ndikuzisandutsa injini pambuyo pa kukanikiza kuti mutsimikizire kuti dongosolo la mafuta limatha kupereka mafuta okhazikika. Makamaka, pampu yamafuta, yoyendetsedwa ndi galimoto yamagetsi yamagetsi, imakoka ndikusintha matupi a nyama, ndipo kenako ndikusefa kwa chipinda cha injini kuti ipangitse galimoto patsogolo.
Mapampo amagwira ntchito bwanji
Pampu ya mafuta nthawi zambiri imayendetsedwa ndi galimoto, yomwe imagwiritsa ntchito njira yothamanga kwambiri ya mota kuti ichotsere, potero ndikupanga malo ozungulira mu thupi la pompo ndikuyenda ku injini kudzera mu mzere wamalonda. Pofuna kuthana ndi vuto la kuwononga mafuta kwa mafuta pomwe mafuta a mafuta ali otsika, pompo mapa pamtunda, omwe amatha kumawonjezera mphamvu pomwe mafuta amachepetsedwa kuti athetse mafuta.
Mitundu ndi mawonekedwe opangira mapapompu ya mafuta
Mapampu a petulo amatha kugawidwa m'magulu awiri malinga ndi njira zosiyana zoyendetsa: makina oyendetsa diaphragm ndi mtundu wamagetsi. Magalimoto amakono amagwiritsa ntchito mapampu amagetsi kwambiri, omwe ali ndi maubwino ambiri mafuta, kuponderezedwa kwakukulu, kukhazikika kwamphamvu, phokoso lotsika, moyo wautali, moyo wautali, moyo wautali, moyo wautali, moyo wautali, moyo wautali, moyo wautali ndi zina zambiri. Kuphatikiza apo, pampu yamafuta imakhalanso ndi ntchito zosiyanasiyana zogwirira ntchito, monga ntchito yothamanga, ntchito yothamanga, etc., kuonetsetsa kuti injini ikhoza kupeza mafuta okhazikika pansi pamachitidwe okhazikika.
Ngati mukufuna kudziwa zambiri, pitilizani kuwerenga nkhani zina patsamba lino!
Chonde ndiyitane ngati mukufuna zinthu ngati izi.
