Kufunika Kwa Mafuta Opaka Mafuta Ndi Volvo Penta Generator Special Mafuta

Kodi mafuta opangira injini ndi ofunikira?Ndikuganiza kuti anthu ambiri adzayankha: zofunika, zofunika kwambiri.Nanga n’cifukwa ciani?Mwachidule, mafuta a injini ndi mafuta opaka injini, omwe amatha kudzoza, kuyeretsa, kuziziritsa, kusindikiza komanso kuchepetsa kuwonongeka kwa injini.Injini ndi gawo la makina ovuta kwambiri, omwe amapangidwa ndi zigawo zambiri zofunika zosuntha, monga pisitoni, crankshaft, camshaft ndi rocker arm assembly.Zigawozi zimakhala ndi liwiro loyenda mwachangu komanso malo osauka, ndipo kutentha kwa ntchito kumatha kufika 400 ℃ mpaka 600 ℃ kapena kupitilira apo.M'mikhalidwe yovuta yotereyi, mafuta a injini amagwira ntchito ngati chitetezo kuteteza mbali zonse za injiniyo kuti zigwire ntchito bwino. Ntchito zazikulu zamafuta a injini ndi:

Ntchito zonse: kuchepetsa kuvala ndi kusunga ukhondo.Kuziziritsa, kupewa dzimbiri, kusindikiza ndi kudzipatula kunjenjemera.

Ntchito yapadera: kuteteza tinthu kudzikundikira, kupewa yamphamvu kukoka, bwino mafuta pa kutentha ndi kuyamba pa kutentha otsika.

Kupewa kuyika kwa kaboni: piston ring groove, siketi ya pistoni, valavu ya mpweya.

Popeza udindo wa mafuta a injini ndizofunika kwambiri ndipo ziyenera kukwaniritsa ntchito zambiri, zimachita bwanji?Mafuta a injini ndi chinthu chosavuta kupanga.Wopanga mafuta amasankha mafuta apamwamba kwambiri ndikuwonjezera zowonjezera zosiyanasiyana malinga ndi ntchito zomwe mafuta a injini amafunikira kuti akwaniritse, kuti apeze chinthu chopangidwa ndi sayansi komanso chololera.Mafuta a injini apamwamba kwambiri komanso oyenerera amatha kukwaniritsa kuyika kwa injini pang'ono, kuchepa kwa zinthu zosiyanasiyana komanso magwiridwe antchito okhalitsa a injini.

Ndiye pali mitundu yambiri yamafuta, ndisankhe mafuta otani?Kodi kusankha bwino injini mafuta?Kusankhidwa kwa mafuta a injini kuyenera kuganizira magawo awiri ofunikira a index: kalasi yapamwamba ndi kalasi ya viscosity, yomwe ingapezeke pa chizindikiro chakunja cha mbiya ya mafuta.

1. Makhalidwe abwino

Pali miyeso iwiri yapadziko lonse lapansi yamafuta a injini ya dizilo:

API giredi (API muyezo), monga CG-4 \ CH-4 \ CI-4.

Muyezo wa ACEA (European Automobile Manufacturers Association standard), monga E3 \ E5 \ E7.

Kukwera mtengo, kumapangitsanso kuchuluka kwamafuta a injini.Posankha, muyenera kusankha mafuta a injini omwe amakumana ndi muyezo malinga ndi malangizo a injini yanu.Mafuta apamwamba a injini amatha kukhala ogwirizana pansi.Komabe, ngati musankha mafuta a injini otsika mukafuna mafuta a injini ya giredi yapamwamba, zingakhudze kugwiritsa ntchito injiniyo ndipo zingawononge injini yanu.

2. Kukhuthala kwa kalasi

Kukhuthala kwa mafuta a injini imodzi kumakhudzidwa kwambiri ndi kusintha kwa kutentha.Kutentha kwapamwamba, mafuta a injini amachepa, komanso kutentha kwapansi, mafuta a injini amawonekera kwambiri.Kuti mukwaniritse ntchito zosiyanasiyana za injini, ntchito yabwino ya kondomu imatha kupezeka pazigawo zosiyanasiyana zotentha komanso kutentha kozungulira.Mafuta a injini amagwiritsa ntchito mafuta okhala ndi mawonekedwe ophatikizika, omwe amawonetsedwa ndi XX W - YY molingana ndi muyezo wapadziko lonse lapansi, Nambala yomwe ili kutsogolo kwa W ikuwonetsa magwiridwe antchito otsika, ndipo nambala pambuyo pa W ikuwonetsa kutentha kwambiri kwa mafuta.Monga momwe chithunzi chotsatirachi chikusonyezera: mwachitsanzo, kutentha kochepa kozungulira komwe mafuta a injini ya 15W-40 akhoza kupirira m'nyengo yozizira ndi madigiri 15.Choncho, posankha mafuta a injini, onetsetsani kuti mumaganizira za malo enieni a malo ogwiritsira ntchito ndikusankha mafuta a injini ndi viscosity yoyenera yomwe ingakwaniritse kutentha kwanyengo yozizira.Ngati kalasi yolakwika ya viscosity yasankhidwa, injiniyo imakhala ndi vuto la mafuta osakwanira m'nyengo yozizira, kuwononga injini pazovuta kwambiri.

Monga tanena kale, pali specifications zosiyanasiyana ndi zofunika posankha injini mafuta.Ogwiritsa ntchito mapeto ayenera kukhala ndi chidziwitso chambiri kuti asankhe mafuta a injini oyenerera.Ndizomvetsa chisoni kuti pali zolakwika zambiri zosafunikira za injini chifukwa cha kusankha molakwika kwamafuta a injini.Kwa ogwiritsa ntchito atsopano ndi akale a jenereta ya dizilo ya Volvo PENTA, timalimbikitsa ndikukulimbikitsani kuti mugwiritse ntchito mafuta a injini ya Volvo PENTA okhala ndi chitsimikizo chapamwamba komanso chapamwamba kwambiri.

Mafuta apadera a Volvo PENTA ndi chiyani?Mafuta apadera a Volvo PENTA ndi mulingo wovuta kwambiri wamafuta a VDS wokhazikitsidwa ndi Volvo Gulu Kutengera miyezo yoyambirira yamakampani a API ndi ACEA komanso kutengera kapangidwe ka injini ya Volvo PENTA.Kuphatikiza pa mayeso omwe adanenedwa ndi API kapena ACEA, mafuta apadera a Volvo opangidwa molingana ndi muyezo uwu alinso ndi mayeso ena apadera a Volvo, monga kuyesa kwa piston sedimentation control, kuyesa kozungulira kwamafuta ndi mayeso angapo okhwima.Mafuta opangidwa motsatira mulingo uwu samangogwira ntchito kwambiri kuposa mafuta amtundu womwewo.Komanso, ndi oyenera Volvo PENTA injini.

Mafuta apadera a Volvo PENTA VDS ali ndi mitundu itatu yamafuta: VDS-2, VDS-3 ndi VDS-4.5.Chonde funsani katswiri wovomerezeka wa Volvo PENTA kuti asankhe mafuta oyenerera a injini yanu.Ndikukhulupirira mafuta apadera a Volvo PENTA akhoza kusamalira bwino zanu Jenereta ya dizilo ya Volvo ndikupereka mphamvu zolimba komanso zopitilira zida zanu.
