Udindo wa pampu yamafuta.
Ntchito ya pampu yamafuta ndikukweza mafuta kufika pa mphamvu inayake, ndikukakamiza mphamvu ya pansi kupita pamwamba pa ziwalo za injini kuti apange filimu yamafuta, yomwe imapereka malo ogwirira ntchito odalirika a zinthu zopanikizika.
Kapangidwe ka pampu yamafuta kangagawidwe m'magulu awiri: mtundu wa giya ndi mtundu wa rotor. Pampu yamafuta yamtundu wa giya imagawidwa m'magulu awiri: mtundu wa giya wamkati ndi mtundu wa giya wakunja, womwe nthawi zambiri umatchedwa pampu yamafuta yamtundu wa giya womaliza. Pampu yamafuta yamtundu wa giya ili ndi mawonekedwe odalirika ogwirira ntchito, kapangidwe kosavuta, kapangidwe kosavuta komanso kuthamanga kwambiri kwa pampu, kotero imagwiritsidwa ntchito kwambiri.
Mfundo yogwirira ntchito ya pampu yamafuta ndikugwiritsa ntchito kusintha kwa voliyumu kuti musinthe mafuta otsika mphamvu kukhala mafuta okwera mphamvu, motero imatchedwanso kuti positive displacement oil pump. Injini ikamagwira ntchito, giya yoyendetsera pa camshaft imayendetsa giya yotumizira ya pampu yamafuta, kotero kuti giya yoyendetsera yomwe ili pa shaft ya giya yoyendetsera imazungulira, motero imayendetsa giya yoyendetsedwa kuti ibwerere mmbuyo, ndipo mafuta amatumizidwa kuchokera m'chitseko cha mafuta kudzera pa backlash ndi khoma la pampu kupita m'chitseko cha mafuta. Izi zimapangitsa kuti pakhale kupanikizika kochepa pa chipinda cholowera, zomwe zimapangitsa kuti mafuta atuluke kuchokera mu poto yamafuta kupita kuchipinda. Ndi kuzungulira kosalekeza kwa giya yoyendetsera ndi giya yoyendetsedwa, mafuta amakanikizidwa nthawi zonse pamalo omwe mukufuna.
Kusuntha kwa pampu yamafuta kungagawidwe m'mitundu iwiri: kusuntha kosalekeza ndi kusuntha kosinthasintha. Kuthamanga kwa mpweya wa pampu yamafuta yosalekeza kumawonjezeka ndi kuchuluka kwa liwiro la injini, ndipo pampu yamafuta yosalekeza imatha kusintha kuthamanga kwa mafuta, kuchepetsa mphamvu yotulutsa, kuchepetsa kukana ndikuchepetsa kugwiritsa ntchito mafuta pokhapokha ngati mafutawo akuchulukirachulukira.
Ngati pampu yamafuta yalephera, monga kuthamanga kwa mafuta sikukwanira kuwonetsa alamu ya kuthamanga kwa mafuta ndi zina zotero, zingayambitse kuwonongeka kwa ziwalo zoyenda za injini chifukwa cha mafuta osakwanira, zinthu zopanikizika sizingafike pamalo abwino ogwirira ntchito, ndipo kuwala kwa injini sikuli bwino, zomwe zingayambitse kuwonongeka kwa injini kwambiri.
Mfundo yogwirira ntchito ya pampu yamafuta
Mfundo yogwirira ntchito ya pampu yamafuta ndi yakuti injini ikagwira ntchito, giya yoyendetsera pa camshaft imazungulira ndi giya yoyendetsera ya pampu yamafuta, kenako imayendetsa giya yoyendetsera yomwe ili pa shaft ya giya yoyendetsera kuti izungulire, kuti itumize mafuta kuchokera m'malo olowera mafuta kudzera pa backlash ndi khoma la pampu kupita ku malo otulutsira mafuta. Njira yozungulirayi imapangitsa kuti pakhale kupanikizika kochepa pa chipinda cholowera, zomwe zimapangitsa kuti mafutawo atuluke m'chidebe chamafuta kupita ku chipindacho. Chifukwa cha kuzungulira kosalekeza kwa magiya akuluakulu ndi oyendetsedwa, mafuta amatha kukanikiza nthawi zonse ku gawo lofunikira. Malinga ndi kapangidwe ka pampu yamafuta, pampu yamafuta imatha kugawidwa m'magulu awiri amitundu yamagetsi ndi mitundu ya rotor, yomwe pampu yamafuta yamtundu wamagetsi imatha kugawidwa m'mitundu yamagetsi akunja ndi mitundu yamagetsi amkati.
Mfundo yogwirira ntchito ya pampu yamafuta yamkati ya giya ndi yofanana ndi yomwe ili pamwambapa, ndipo kudzera mu giya yoyendetsera pa camshaft imazungulira giya yoyendetsera yokhazikika pa shaft ya giya yoyendetsera, ndikuyendetsa giya yoyendetsedwa kuti izungulire mbali ina, ndipo mafuta amatumizidwa kuchokera m'khola lolowera mafuta motsatira kumbuyo ndi khoma la pampu kupita ku khola lotulutsira mafuta. Kupopera kwamphamvu kochepa kumapangidwa pamalo olowera a chipinda chamafuta, ndipo mafuta omwe ali mu poto yamafuta amayamwa kulowa mu chipinda chamafuta. Chifukwa magiya akuluakulu ndi oyendetsedwa amakhala akuzungulira nthawi zonse, mafuta amakanikizidwa nthawi zonse ku gawo lofunikira.
Mfundo yogwirira ntchito ya pampu yamafuta a injini imayendetsedwa ndi injini kuti iyendetse giya kapena chozungulira chomwe chili m'thupi la pampu kuti chizungulire, kotero kuti mafuta amatumizidwa kuchokera ku chipinda cholowera mafuta motsatira kumbuyo ndi khoma la pampu kupita ku chipinda chotulutsira mafuta. Ubwino wa pampu yamafuta a injini ndikuti kuthamanga ndi kuyenda kwa mafuta kumatha kulamulidwa mwa kusintha liwiro la mota, zomwe ndizoyenera nthawi zina pomwe makina opaka mafuta amafunika kuwongoleredwa bwino.
