Ogwira ntchito auto ndi eni ayenera kumvetsetsa chidziwitso chamafuta!

Za mafuta, mafunso awa, mwina mukufuna kudziwa kwambiri.

1 Kodi kuya kwa utoto wamafuta kumawonetsa magwiridwe antchito?

Mtundu wamafuta umatengera mawonekedwe a mafuta oyambira ndi zowonjezera, mafuta osiyanasiyana ndi zowonjezera zimapangitsa mafuta kukhala akuwonetsa mawonekedwe osiyanasiyana.

Kuchita kwamafuta kumawunikidwa kudzera kumayesedwa angapo a benchi ndi mayeso enieni a pamsewu, omwe amayesa magwiridwe antchito am'madzi, kututa, mphete, sludes, kuvala ndi zina.

2 Zosavuta kutembenuka mafuta akuda kuyenera kukhala zoyipa?

Osati kwenikweni, mafuta ena abwino ali ndi zowonjezera zomwe zimatha kusungunula za kaboni mkati mwa injini, kotero ndizosavuta kukhala zakuda, koma sizikukhudzanso magwiridwe antchito.

3 Chifukwa chiyani ndiyenera kusintha mafuta nthawi zonse?

Mafuta amaika pang'onopang'ono pakugwiritsa ntchito, zifukwa zazikulu ndi izi:

① Kuphatikiza zopangidwa ndi zinthu: monga madzi, asidi, soot, kaboni, ndi zina;

② Mafuta amafuta;

③ Kutentha kwambiri kwa oxidation kuwonongeka kwa mafutawo;

④ fumbi ndi zitsulo.

Zinthu izi zimapezeka mu mafuta, nthawi yomweyo, zowonjezera mu mafuta zidzathenso kugwiritsa ntchito njirayi. Ngati mafuta sanasinthidwe pakapita nthawi, kumachepetsa kwambiri chitetezo cha mafuta pa anti-kuvala.

Kusintha mafuta sikungangotulutsa zodetsa mu mafuta, komanso onetsetsani kuti kapangidwe ka mafuta kumasungidwa moyenera.

4 Mukasintha mafuta, bwanji mafuta amasulidwa kwambiri?

Mafuta akasinthidwa, nthawi zambiri amapangidwa mugalimoto yotentha, ndipo ma vinyayo amachepetsa kutentha, motero mamasukidwe a mafuta okhala ndi mafayilo ochulukirapo kuposa mawonekedwe a firin, yomwe ndi yotentha.

Komabe, kutentha kwa kutentha kwa chipinda, ma virus akumafuta akadali otsika kwambiri, omwe amayamba chifukwa cha kuchepetsedwa kwa mafuta panthawi yogwiritsa ntchito mafuta.

5 Kodi Mungasankhe Mafuta?

① Kulimbikitsidwa ndi depot kapena malo ogwiritsira ntchito;

② Malinga ndi vuto lagalimoto;

Malinga ndi kutentha kozungulira.

6 Momwe mungayang'anire kuchuluka kwa mafuta omwe amagwiritsidwa ntchito?

Maonekedwe:

Sample ya mafuta ndi mkaka kapena nkhungu, chosonyeza kuti mafuta alowa m'madzi;

② Mafuta amasuntha mafuta ndipo akhoza kuipitsidwa ndi mafuta;

③ Kusanduka zakuda, zomwe zimayambitsidwa ndi zomwe sizingatheke.

Fungo:

Kununkhira kosadetsa kumawonekera, kuwonetsa kuti mafuta ayatsidwa ozizira pamtunda wokwera;

② Kununkhira kolemera kwambiri kwa mafuta, kuwonetsa kuti mafutawo amasungunuka kwambiri (amagwiritsidwa ntchito mafuta ochepa amakola thupi).

Mayeso a mafuta amaponya:

Tengani dontho la mafuta papepala ndikuwona kusintha kwa mawanga.

① Kuphatikizika kwa mafuta mwachangu, popanda phula pakati, lomwe likuwonetsa mafuta abwino;

② Difviition yamafuta imachedwa, ndipo pali malo osungirako pakati, kuwonetsa kuti mafutawo achita chonyansa ndipo ayenera kusinthidwa.

Kuyesa kwa Bust:

Phazi lachitsulo loonda limakonzedwa mpaka 110 ° C, ponyani dontho la mafuta, monga mafuta kuphulika kutsimikizira kuti mafuta ali ndi madzi, njira iyi imatha kudziwa zamadzi zoposa 0,2%.

7 Zifukwa ziti za alamu yamafuta?

Kuwala kwamafuta kumachitika makamaka chifukwa chosakwanira kwa mafuta m'madzi, nthawi zambiri pazifukwa zotsatirazi:

Kuchuluka kwa mafuta mu poto poto sikukwanira, ndikuwona ngati pali chidindo cholimba chomwe chimayamba chifukwa cha kutayikira kwamafuta.

Mafuta amaphatikizidwa ndi mafuta kapena katundu wa injini ndi wolemera kwambiri ndipo kutentha kumakhala kwakukulu kwambiri, kumapangitsa kuti magazi wamafuta ukhale wowonda.

Pulogalamu yamafuta imatsekedwa kapena mafuta ndi yodetsedwa kwambiri, chifukwa cha kuchuluka kwa mafuta osayenera.

④ Pampu yamafuta kapena mafuta othamanga kapena ma valve valavu okakamira akugwira ntchito molakwika.

⑤ Kuyeretsa kwamatumbo ndikokulirapo, monga crankshaft yonyamula khosi komanso chitsamba cholumikizira, ndikupangitsa kuti chitsamba chikuchepetsetsa kwambiri, ndikupangitsa kusiyana kwa mafuta ndikuchepetsa kuthamanga kwa mafuta mu gawo lamafuta.

⑥ sensor yamafuta siyikuyenda bwino.

7 Palibe chisankho cholondola cha mamasukidwe amafuta malinga ndi nyengo ndi injini zogwirira ntchito.

Kusankhidwa kwa mafuta otsika kwambiri kukuwonjezera kutaya kwamafuta yopaka mafuta odzola, kupangitsa kukakamizidwa kwa gawo lalikulu kuti likhale lotsika. Kusankhidwa kwa mafuta okwera kwambiri (makamaka nthawi yozizira), komwe kumapangitsa pampu yamafuta kuti ikhale yovuta kapena yolusa mafuta kapena kuwononga mafuta ochepa m'dongosolo.
