Pampu ya Mafuta a Magalimoto: "Mtima Wopaka Mafuta" wa Injini ndi Kasamalidwe ka Zolakwika
Mu dongosolo lovuta la injini ya galimoto, pampu ya mafuta ingawoneke ngati yopanda ntchito, koma ndi chimodzi mwa zigawo zazikulu zomwe zimatsimikizira kuti injini ikugwira ntchito bwino, ndipo ikhoza kuonedwa ngati "mtima wothira mafuta" wa injini. Kugwira ntchito kwake kokhazikika ndiye maziko a ntchito yogwira mtima komanso yokhalitsa ya zigawo zosiyanasiyana za injini.
Ntchito yaikulu ya pampu yamafuta
Udindo waukulu wa pampu yamafuta ndikupereka mafuta okhazikika komanso osalekeza ku ziwalo zoyenda mkati mwa injini. Pa nthawi ya injini, zida monga ma pistoni, ma crankshaft, ndodo zolumikizira, ndi ma camshaft zimayenda mofulumira kwambiri, zomwe zimapangitsa kukangana kwakukulu. Popanda mafuta ofunikira, kukangana mwachindunji pakati pa zida zachitsulo kumabweretsa kuwonongeka kwakukulu komanso ngakhale zolakwika zazikulu monga kutentha kwambiri ndi kugwira. Pampu yamafuta imakakamiza mafuta kuchokera mu poto yamafuta ndikutumiza kumadera osiyanasiyana opaka mafuta, ndikupanga filimu yamafuta pamwamba pa zida, monga kuyika "buffer pad" yosalala pakati pa malo okangana, kuchepetsa kwambiri friction coefficient ndikuchepetsa friction component, motero kukulitsa moyo wa ntchito ya injini.
Kuwonjezera pa kudzola mafuta, pampu yamafuta imagwiranso ntchito zoziziritsa, kuyeretsa, ndi kutseka. Mafuta ozungulira amatha kuchotsa kutentha komwe kumachitika chifukwa cha kukangana kwa zigawo, kuteteza kutentha kwambiri kwa injini ndikusunga kutentha koyenera. Nthawi yomweyo, mafutawo akamayenda amanyamula zinyalala zachitsulo ndi zonyansa zomwe zimapangidwa ndi injini, zomwe zimachotsedwa ndi fyuluta yamafuta kuti mkati mwa injini mukhale oyera. Filimu yamafuta yomwe imapangidwa ndi mafuta pakati pa pistoni ndi khoma la silinda ingathandizenso kutseka chipinda choyaka moto, kupewa kutulutsa kwa mpweya ndikuwonetsetsa kuti mphamvu ya injini ikugwira ntchito bwino.
Poganizira mfundo yogwirira ntchito, pampu yamafuta imapanga kuyamwa kudzera mu kusintha kwa voliyumu ndikuyamwa mafuta kuchokera mu poto yamafuta, kenako nkuwakakamiza ndikutumiza ku fyuluta yamafuta ndi njira zosiyanasiyana zoyeretsera. Pakadali pano, mitundu yayikulu ya mapampu amafuta ndi mtundu wa giya ndi mtundu wa rotor. Pampu yamafuta yamtundu wa giya imagwiritsidwa ntchito kwambiri m'mainjini ambiri chifukwa cha kapangidwe kake kosavuta, magwiridwe antchito odalirika, komanso kuthamanga kwamafuta okhazikika pampu; pampu yamafuta yamtundu wa rotor, yokhala ndi zabwino monga phokoso lochepa, kusweka kochepa, komanso kusinthasintha kwa liwiro, ikukula pang'onopang'ono mukugwiritsa ntchito m'mainjini omwe amaika patsogolo bata ndi magwiridwe antchito apamwamba.
Zizindikiro zodziwika bwino za kulephera kwa pampu yamafuta
Ngati pampu yamafuta yalephera, idzakhudza mwachindunji magwiridwe antchito abwinobwino a injini ndikuyambitsa zizindikiro zingapo zosazolowereka. Choyamba, mphamvu ya injini imachepa. Pampu yamafuta yolephera imabweretsa mafuta osakwanira, kukana kukangana pakati pa zigawo, komanso kuchuluka kwa katundu wogwirira ntchito ya injini. Mukaponda accelerator, liwiro la injini limakwera pang'onopang'ono, ndipo pamakhala kusowa kwakukulu kwa mphamvu pothamanga kapena kukwera mapiri, kapena ngakhale kugwedezeka. Chachiwiri, kuyambitsa kumakhala kovuta. Pampu yamafuta singathe kupompa mafuta mwachizolowezi, ndipo injini imayamba ndi mafuta osakwanira, kukangana kwakukulu, zomwe zimapangitsa kuti nthawi yoyatsira ikhale yayitali, ndipo pamafunika kuyesera kangapo kuti iyambitse, makamaka injini ikakhala yozizira. Chachitatu, phokoso losazolowereka la injini. Kusakwanira kwa mafuta kumayambitsa kukangana kouma kwa zigawo, zomwe zimapangitsa kuti phokoso "lizime" kapena phokoso "logwedezeka" la kukangana kwachitsulo, zomwe zimakhudza kwambiri kuyendetsa galimoto ndipo zimasonyeza kuti zigawo za injini zikuwonongeka. Chachinayi, kuthamanga kwa mafuta kosazolowereka ndi alamu. Pampu yamafuta yolephera imayambitsa kuchepa kwa kuthamanga kwa mafuta, ndipo choyezera kuthamanga kwa mafuta chidzawonetsa mitengo yochepera pamlingo wabwinobwino. Nthawi yomweyo, njira yowunikira kuthamanga kwa mafuta a galimoto idzayambitsa kuwala kwa cholakwika, kudziwitsa dalaivala kuti ayang'ane nthawi. Chachisanu, kugwedezeka kwa injini ndi utsi wakuda wochokera mu chitoliro chotulutsa utsi. Kukangana kwakukulu pakati pa zigawo kumasokoneza kukhazikika kwa ntchito ya injini, zomwe zimapangitsa kuti kugwedezeka kukhale kosagwira ntchito kapena panthawi yoyendetsa; mafuta osakwanira amasokonezanso njira yoyatsira mafuta, zomwe zimapangitsa kuti mafuta asayaka bwino, ndipo mafuta osayaka amatuluka, zomwe zimayambitsa utsi wakuda wochokera mu chitoliro chotulutsa utsi.
Zifukwa ndi njira zothetsera vuto la kulephera kwa pampu yamafuta
Zomwe zimayambitsa kulephera kwa pampu yamafuta makamaka ndi kutha, kutsekeka, kusalumikizana bwino, ubwino wa mafuta, ndi mavuto ndi zida zoyendetsera. Kugwiritsa ntchito nthawi yayitali kungayambitse kutha kwa magiya amkati, ma shaft, ndi zina zotero mu pampu yamafuta, zomwe zimakhudza magwiridwe antchito; zinyalala mumafuta zitha kutseka fyuluta kapena njira zamafuta, kulepheretsa kuyenda kwamafuta; kusalumikizana bwino panthawi yokonza kudzapangitsa kuti pampu yamafuta isagwire ntchito bwino; Kugwiritsa ntchito mafuta a injini otsika mtengo kudzawonjezera ntchito ya pampu yamafuta, ndikuwonjezera kuwonongeka kwake; maunyolo omasuka kapena osweka kapena malamba omwe amayendetsa pampu yamafuta nawonso adzakhudza kutumiza kwa mphamvu.
Mukawona zizindikiro zilizonse za kulephera kwa pampu yamafuta, muyenera kuchitapo kanthu mwachangu. Choyamba, sankhani pampu yamafuta yodalirika kuti muyikenso ndikuwonetsetsa kuti yayikidwa bwino. Mukasintha pampu yamafuta, yeretsani dera lonse lamafuta, chotsani zotsalira, yang'anani unyolo woyendetsera kapena lamba, fyuluta yamafuta ndi zina zokhudzana nazo kuti muwonetsetse kuti zili bwino. Pakukonza tsiku ndi tsiku, gwiritsani ntchito mafuta a injini apamwamba omwe akugwirizana ndi zofunikira zagalimoto, sinthani mafuta ndi fyuluta nthawi zonse, samalani momwe kuwala kwa mafuta kumayendera, yang'anirani mosalunjika momwe pampu yamafuta imagwirira ntchito, ndikuyang'ana magawo ofunikira monga kuyera kwa thupi la pampu ndi digiri ya meshing ya giya panthawi yokonza akatswiri kuti apewe mavuto asanachitike.
Pompu yamafuta ndi gawo lofunika kwambiri la injini, ndipo ntchito yake singathe kusinthidwa. Kumvetsetsa ntchito zake, zizindikiro za cholakwika ndi njira zoyankhira kungathandize eni magalimoto kuzindikira mavuto pakapita nthawi, kuonetsetsa kuti injini ikugwira ntchito bwino, ndikuwonjezera nthawi ya moyo wa galimotoyo.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
