Mazgu ghakwamba ghachoko waka ghakuŵikamo mafuta

Pampu ya mafuta ni pampu yakupepuka na yakukhora, iyo yili na vigaŵa vitatu: mu -line, yakugaŵika na yimoza- thupi. Pampu ya mafuta yikukhumbikwira nkhongono yakugwiliskira ntchito, ndipo camshaft pa chigaŵa chake chapasi chikulongozgeka na magiya gha crankshaft gha injini.
Pampu ya mafuta yikukhumba kuti pampu ya mafuta yiŵe na nyumba yakupangika na aluminiyamu -ŵanzeru na chigaŵa icho chikupangika mu nyumba, umo chigaŵa icho chikupangika na kusunkhunyika chikupangika na chisulo cha sintentable - alure alloy iyo yili na austenite yimoza, ndipo umo chigaŵa chakupangika na chinthu chakupangika chili na coefficient yakusazgikira ya 60% ya . thermal kukuzga coefficity ya nyumba.
Chigaŵa chikuru cha pampu ya jekeseni ya mafuta ni plunger. Usange syringe yakumanyikwa mu chipatala yikugwiriskirika nchito nga ni ntharika, mbwenu pulagi yakusunthika yikuchemeka plunger, ndipo syringe yikuchemeka kuti plunger sleeve. Kughanaghana kuti spring yikuŵikika mu sirinji kuti yikhozgere kumapeto yimoza ya plunger, ndipo umaliro unyake wa plunger ukukhwaskana na camshaft, apo camshaft yikuzungulira mzere umoza wakuzungulira, plunger yizamukwera pachanya na pasi kamoza mu mkono wa plunger. Iyi ndiyo nthowa yakwamba yakusuntha ya plunger ya pampu ya jekeseni ya mafuta.
Ma plunger na plunger sleeve ni vigaŵa vyakuyana chomene ivyo vikupangika. Pali groove yakukhota pa plunger, ndipo mbuna yichoko pa mkono wa plunger yikuchemeka kuti doko la kunyamuka. Doko ili la kuyamwa lazura na dizilo. Para mtundu wa plunger ukulimbikira kukumana na doko lakuyamwira, dizilo yikunjira mu mkono wa plunger. Para plunger yikukankhika kufika pa msinkhu unyake na camshaft, mtundu wa plunger uwo ukupendera ukukhwaskika na doko lakuyamwira, ndipo doko lakuyamwira likujalirika, mwakuti dizilo yingayamwa yayi panji kuŵikikamo. Para plunger yikulutilira kukwera, yikuchichizga dizilo. Para nkhongono ya dizilo yikufika pa mlingo unyake, yizamukankhira kujura vavu yimoza na kuchimbilira kuwaro mu nozzle ya mafuta, ndipo pamanyuma pake munjire mu chipinda cha combustion cha silinda kufuma ku nozzle ya mafuta ghakuŵikamo mafuta. Nyengo yiliyose para plunger yikufumiska dizilo yinyake, chigaŵa chimoza pera icho chikuponyeka mu silinda, ndipo vinyake vyose vikudontha kufuma mu mbuna ya mafuta ghakuwelera, ndipo ndalama zakuŵikamo zikusinthika mwa kukwera panji kuchepeskako unandi wa mafuta ghakuwelera ghakuvundulika. Para plunger yikukwera ku "malo ghakukwera" ndipo yikuluta pasi, plunger iyo yikukhotakhota yizamukumana na doko la kuyamwaso, ndipo dizilo yikuyamwaso mu mkono wa plunger, kubwerezgaso ivyo vyayowoyeka pacanya apa. Gulu lililose la ndondomeko za plunger cha mu - jekeseni ya mafuta yikuyana na silinda yimoza, ndipo pali magulu 4 gha ndondomeko za plunger kwa masilinda 4, ntheura buku ili ndakuru chomene, ndipo likugwiriskirika nchito chomene mu magalimoto ghapakatikati ({13}}}}2 silized na ghakuru. Mwachiyelezgero, injini za dizilo pa mabasi na magalimoto ghanandi kanandi zikugwiriskira ntchito mu mapampu ghakuŵikamo majeleni ghakuŵikamo mabasi.
